Stormdry Brick Sealer & Application

Tue, 25 May 2021 00:00:00 +0000

Without proper protection, penetrating dampness and heat loss can be a major problem in many buildings. Solid brick and stone wall constructions are often favoured by homeowners for their authentic and attractive look but can be particularly vulnerable to the effects of flooding and poor weather conditions, due to the fact that they are more difficult to insulate.

At Extract Insulation, our specialists can offer advice on the best ways to overcome damp and heat loss in your home. In many cases, we recommend the Stormdry™ application to protect your home from penetrating dampness without sacrificing the aesthetic qualities of your masonry.

What Is Stormdry Brick Sealer?

Stormdry™ is a colourless cream that has been scientifically tested to protect the masonry from the effects of rain penetration for up to 30 years in a single application. The most advanced product of its kind on the market, the Stormdry™ application creates an invisible barrier against moisture, while allowing the masonry to breathe and retain its original looks and features.

In addition to protecting against dampness, Stormdry™ application also creates warmer walls – minimising heat loss and helping you to cut down on your carbon emissions and save money on your energy bills. It can also act as an effective flood barrier as part of a flood resilient system and encourages walls to dry out more quickly after flooding occurs.

How Can Extract Insulation Help?

At Extract Insulation, we offer a complete Stormdry™ installation service guaranteed to leave your home warmer, drier and better protected, with no impact on the overall appearance of your property. Our installation specialists will inspect your building to assess whether it is suitable for the Stormdry™ application. If you decide to go ahead, we will also conduct any necessary preparation work – such as drying, cleaning and repointing the surface – before applying the Stormdry™ mix. Once applied, the mix will penetrate the brickwork and become colourless, returning your masonry to its original colour within 24 to 48 hours.

Stormdry™ has been independently tested and certified to perform to EN ISO 15148, this is a direct equivalent to BS (British Standard). A single coat application can save up to 29% energy, effectively reducing your carbon emissions. It is the result of over 10 years of research and development and has been scientifically proven to outperform competing products, thanks to a unique Silane/Siloxane formula that has been extensively tested on a variety of masonry.

The Commonest Cavity Wall Insulation Problems?

Tue, 25 May 2021 00:00:00 +0000

It's true that Energy companies are gung–ho about cavity wall insulation and are even offering the service for free to septuagenarian homeowners. But our cavity wall insulation removal company receive a lot of emails where homeowners are requesting for pro–assistance to remove cavity wall insulation. Yes, the CIGA might be upholding CWI in a positive light but cavity wall insulation can cause damp problems – and the worst part is that many of the homeowners are unable to detect that it's the insulation problems that are actually causing it. As an expert in CWI removal, I am going to explain the typical issues with cavity wall insulation.

What is the damp issue?

In most cases, insulation is attached to the inner leaf of the cavity which leaves a very narrow gap for the rainwater which penetrates the outer brick–leaf. The insulation material is mostly manufactured from waterproof foam boards or semi-rigid glass fibre batts and mineral wool. The fibres stay vertically aligned allowing penetrating rainwater into the cavity but there is no means of transferring this across the outer leaf.

Now, BRE has found out that the single-leaf walls leak while exposed to wind-driven rain – leading to damp patches. This leakage takes place at vertical joints in between adjacent bricks given mortar shrinkage. Our prolonged experience in the industry has helped us understand that this problem is not due to poor workmanship but is an inevitable aspect of such constructions.

What's in your cavity wall?

Our recent project in Brighton had blown mineral-wool fibre as the basic cause for CWI issues. In fact, this material has been the cause of most of our client's insulation problems. Before elaborating – we should mention that CWI damp problem is especially prevalent in houses constructed before the 1980s.

It is claimed that mineral-wool fibre is water–repellant and it doesn't allow the penetrating rainwater across the cavity. However, my experience has proved that this material actually absorbs water. Our samples show a whopping 243% moisture in cavities installed with mineral–wool insulation fibre.

Increased condensation

One of our projects at Southampton showed us that CWI can even create dampness issues through heightened condensation – even if the insulation fibre is not resulting in rainwater penetration across the cavity. There is a wide range of homes around where cavity walls suffer from insulation gaps. Those voids lead to increased condensation and black moulds inside the house.

Do I have damp?

Tue, 25 May 2021 00:00:00 +0000

It's an unfortunate but inescapable fact that many British homes fall prey to dampness. Damp damage doesn't just look unpleasant. It can literally ruin years of the most careful property maintenance and decorating. And, somewhat worryingly, it can contribute to serious structural damage. But, perhaps more worrying than all of these issues: dampness is often a danger to health, making it an absolute priority to establish what kind of dampness you have and how best to treat it to eradicate the problem.

Rising Damp

Rising damp happens once water is soaked up via a building's brickwork, bypassing wherever the damp-proof course ought to be. This might simply be a result of faulty damp proofing; or it may be a result of having no damp–proof course in place at all (sadly, common in older buildings). Rising damp in a property is fairly easy to spot – it can be as obvious as a 'tide mark' on the external masonry.

Penetrating Damp

Penetrating damp happens once wetness soaks through the outer masonry, eventually reaching the interior gypsum layer. You will see damaged wallpaper which is peeling off or obvious plaster bubbles. You might even spot mould growing on the inner surfaces. This may merely be the result of constant wind and driving rain attacking an exceeding weather-exposed property. However, it can also be the result of defects within the roofline or the brickwork. Click here to find out how best to manage your property's maintenance by managing the threat of dampness occurring from driving rain. If the property suffers from penetrating dampness and has previously been treated with wall insulation then there's a risk that the wall insulation could become wet. If the wall becomes wet, drying it out can prove to be an immense task, which in all probability, will lead to the need for it to be removed completely.

Condensation

Condensation is frequently experienced by property owners. Put simply, it happens when a building has insufficient ventilation to deal with excess moisture.

In most cases, we'd recommend a professional property survey to identify the scale of the problem – a company specialising in moisture problems or if you suspect wall insulation damage, a cavity wall insulation removal specialist.

Local Authorities, Housing Associations, And Building Contractors

Tue, 25 May 2021 00:00:00 +0000

Here at Extract Insulation, we work with a variety of organisations to deliver insulation services across the whole of their property portfolios. Whether you're involved in building new properties to meet housing demand or need existing homes retrofitting to improve standards throughout your stock, our team guarantees to deliver a professional service that you can rely on.

Our services suit the needs of local authorities, housing associations, build contractors and other property organisations, giving complete control and flexibility.

Why Should You Be Considering Insulation?

Firstly, it's now a legal obligation for rented properties to have at least an EPC rating of E. That means properties need to consider measures that help homeowners to reduce the amount they're spending on energy. Loft and cavity wall insulation installations are one of the most cost-effective ways you can improve your EPC rating when compared to alternative methods. It makes insulation the go-to option for a range of organisations.

On top of the legal requirement, effective insulation can entice both renters and buyers who have become savvier to EPC ratings. It might mean an initial cost but it's one that will be paid back over the long term.

Extract Insulation Experience

Our team can be relied upon to complete a range of insulation services, whether you need poor insulation removing and replacing or a complete inspection of an entire portfolio. We've worked within the insulation space for almost two decades and it's our experience that sets us apart.

We've worked with numerous housing organisations to improve the EPC rating of their properties on time, within budget, and always to a high standard.

How Is Cavity Wall Insulation Removed?

Fri, 30 Jul 2021 00:00:00 +0000

Here at Extract Insulation, we believe cavity wall insulation (CWI) can be a wonderful thing – it’s a cost-effective way to keep your home warm in the winter months and homeowners can reap the benefits almost immediately. But, if not done properly, cavity wall insulation can create more problems than it solves. This is why we’ve dedicated our time to removing inadequate and ineffective CWI – but how exactly do we do it?

To the uninitiated, the process may seem daunting, but here’s our step by step guide on how we remove CWI:

We start by pulling out a brick from the bottom of your property. This is done with a specialist tool, the Arbortech Allsaw, to ensure we can save the original brick and put it right back into place once the process is complete.
We then attach a large extraction hoover to the wall, which is an important part of the overall process.
A series of 22mm holes are drilled into the external walls of the property, using a strategic drill pattern.
An extra row of holes is then drilled three bricks above the property’s damp proof course. This ensures that all of the cavity wall fill is sucked out by the extraction machine, so no insulation remains above the point of the damp proof course.
This is where the fun really begins – starting at the hole closest to the hoover, we used compressed air to force the insulation toward the hoover. This works by causing a gap in the insulation, allowing the material to be sucked out. We’ll then move on to the level above, forcing the next section downward and so on until all the insulation has been sucked into the extraction hoover.
We will then bag up the extracted material for you, and remove it from your property under a waste carrier’s license.
To ensure the process has gone smoothly, we will check your property with a boroscope. We can even allow you to see our impressive work for yourself by connecting an iPhone to the boroscope and taking pictures and videos inside your cavity walls which you can keep for your records.
To finish off the job, all flues, chimneys, and gas vents will be checked by a competent and accredited professional to ensure your property is fine.

So there you have it, cavity wall extraction explained!

If your CWI is causing problems in your home such as dampness, get in touch with us today and we can help you extract it.

Why Wet Cavity Wall Insulation Occurs

Wed, 18 Aug 2021 00:00:00 +0000

Thanks to government policy more and more homes across the UK are having cavity wall insulation installed. While it can be beneficial to the homes installed when done correctly if it’s done on an unsuitable property or has been installed wrong it can lead to the insulation becoming damp, potentially causing both health and structural issues.

When cavity wall insulation is installed it can help cut heating bills. External walls account for around a third of the heat loss in the average home and some studies suggest that for every square metre of cavity wall insulation a tonne of carbon dioxide will be saved over the average building's life. Not only does this help the government achieve climate change goals but it can cut household bills.

While there are benefits, cavity wall insulation can also fail and cause additional problems, including when it becomes damp. One of the ways insulation becomes wet is if it’s installed in an unsuitable building, including those that regularly experience wind-driven rain. Mortar that is in a poor state of repair, properties experiencing flood damage and water tracking across rubble can also cause the insulation to become damp.

It can be difficult for issues with cavity wall insulation to be spotted early on, with some problems not showing any outwards signs until a few winters have passed. Signs that your insulation has become wet include plaster blistering and crumbling and mould growth. While at first the problems of wet wall cavity installation might be mild, if left unchecked they can have a serious impact. Not only does mould look unseemly it can have an impact on your health, being linked to cold-type symptoms, skin irritation and asthma attacks, and the structure of your home.

Should you suspect your cavity wall insulation has become damp there are a number of ways professionals can assess if you have any serious issues. The techniques include thermal imagery, moisture and damp meters and brick removal.

Should your insulation have become wet it is very difficult to dry out and will typically need to be removed. This not only means additional work taking place in your home but it can quickly result in costs mounting up, including the cost of hiring a professional company to do the work and repairing any damage that the damp has caused inside your home.

Cavity Wall Insulation Costs

Tue, 05 Oct 2021 00:00:00 +0000

Want to know the benefits of cavity wall insulation and how much it will cost you?

About a 1/3 of the heat lost from your home disappears through the uninsulated cavity walls. That's a significant proportion of your energy bill. So, if you insulate your walls, you'll save money and do your bit for helping the environment & planet.

Houses built from 1920 onwards will have cavity walls. But, how are they constructed? A cavity wall has two leaves of brickwork separated by a cavity, and the two leaves are held together with wall ties.

Its purpose is to prevent dampness from wind-driven rain from travelling from the outside surface to the inner plastered and decorated cover. Having a cavity precludes the onset of the various types of dampness common in houses older than this. To a certain extent, it also provides a degree of heat insulation as air is a worse heat conductor than brick.

However, to further insulate your walls, a specialist approved contractor injects one of the following materials into the cavity through small drilled holes.

Polystyrene beads
Mineral wool
Rockwool

Afterwards, the insulation contractor seals the holes with cement mortar.

How Much Does Cavity Wall Insulation Cost?

The cost of cavity wall insulation will vary depending on the size of your home. But, no matter how large your home is, you can usually recoup the insulation cost in about five years from the savings in your energy bills.

To put it in figures you can understand, it will cost about £12 m2 depending on the insulating material, glass wool is the cheapest. So, if you own a typical three-bedroom property in the UK, it'll usually cost between about £800 and £1200 in total.

To look at this in more detail, let's look at some more average estimated cavity wall insulation costs.

Type of house Estimated cost

Mid terraced £600 to £800

Semi-detached £800 to £1200

Detached At least £1200

Detached bungalow About £700

Unfortunately, if you live in a flat, it's a bit more complicated because your neighbours must also agree to share the cost.

House Cavity Insulation Cost Factors

A few factors determine the wall insulation costs and the type of insulation to install in your walls.

Wall type

Houses built before 1900 have solid walls that aren't suitable for cavity wall insulation. Homes built from about 1920 onwards will have cavity walls. The cavity should be a minimum of 50mm across and extend around the entire house above the damp proof course level and free from rubble.

Insulation material

Polystyrene beads are white, grey or black granules and are the best insulator—they cost from £18 to £22 per m2.

How Long Does The Job Take?

The entire job doesn't take very long to do, but it's worthwhile knowing the steps so you can appreciate what happens.

Preparation

Confirm you need insulation. If you already have insulation, you may need it removed if an older foam that doesn't meet standards today. Get a specialist borescope surveying company to drill a hole and insert a borescope camera. A borescope is a small camera and light source on the side end of a fixed wand. The boroscope can be inserted through a pre-drilled hole into the cavity. The assessor can then inspect the cavity wall and whatever is inside. The report will detail the condition of the cavity and whether it is suitable for injected insulation. Some wall types, those without a cavity or timber-framed buildings, will not suit cavity wall insulation.
We will check the condition of the walls and repair any obvious cracks or holes that might allow the insulation to escape the cavity.

Insulation

Drill 22mm holes at 2–metre horizontal intervals along the wall.
The insulation nozzle on a hose will be inserted into the holes.
Inject the insulation into each hole, in turn, keeping an eye on the back pressure.
When the wall is full of insulation, fill the holes with cement mortar and tidy up the area.

Completion

We will issue an independent 25 Guarantee.

How Much Can I Save On Energy Bills?

This depends on what type of insulation you decide to use and the kind of property—For example, a small bungalow will cost about £700, and you'll potentially save about £120 per year. While a detached house will cost about £1200 and you'll save about £350 per year. On average, however, you can usually make your money back in about five years or so. And, considering that the insulation doesn't usually need replacing for a very long time, this sounds like a good investment.

Cavity Wall Insulation Cost Q&A

Is there financial help towards having your walls insulated?

If you receive certain income-related or disabled benefits, there is money available to help with the cost.

How long does cavity wall insulation last?

The National Insulation Association and the Cavity Insulation Guarantee Agency (CIGA) both represent their members consisting of manufacturers and installers. CIGA issues an independent 25–year guarantee for cavity wall insulation installed by registered installers who are also members.

Usually, cavity wall insulation lasts anywhere from 25 years.

Will cavity wall insulation stop damp?

Damp caused by cavity wall insulation is very rare, but it does happen. Usually, it occurs if there's a combination of the following factors.

The weather in your area is such that the house is exposed to severe wind-driven rain. Usually, this is in Northern Ireland, most of Wales, most of Scotland and the west of England.
You haven't got any trees or other buildings to shelter your building, and you live in an exposed location.
Your external walls are in poor condition, poorly built or sloppily maintained. Usually, this shows cracks in the brickwork or render.

How do you fix dampness in cavity wall insulation?

Houses with cavity wall insulation will usually become damp if the outside brick leaf isn't weatherproof and the damp condenses onto the insulation within the cavity. There are two methods you can use to fix this problem.

A resin-based textured wall coating for external walls. Firstly, the contractor does all visible repairs such as cracks, holes, loose rendering, repointing, etc. Then, apply the exterior coating. Your walls will be weatherproof and won't usually need painting for 20 to 25 years. Depending on the brand you choose, you'll also receive a guarantee for about 20 years.
A damp proof wall coating. This application protects the outside wall from rain. And, as it's colourless, it won't change your home's appearance. This is especially important if you live in a listed building.

What happens when cavity wall insulation gets wet?

If you have poorly maintained walls or the cavity wall insulation isn't installed correctly, you can often experience condensation and damp penetration. The rain soaks through the outside bricks and reaches the edge of the cavity getting the fibreglass insulation wet causing dampness on the inside walls.

Can I remove cavity wall insulation myself?

No, A specialist company like Extract Insulation will require you to know the procedures and have specialist equipment. Also, it's challenging to find a waste site that will accept a large amount of insulation material.

Bricks must be removed at intervals along the wall, and the insulation removed using a large and powerful vacuum machine. If you have mineral or glass fibre insulation, the vacuum machine sucks the fibres out of the cavity. However, if you have polystyrene beads or urethane foam, you must first break up the solid mass using a specialist machine before it's vacuumed out.

How much does cavity wall insulation removal cost?

This cost will vary depending on the type of insulation you wish to remove. On average, however, the price is between £20 and £25 per m2. For a typical semi-detached house of about 80m2, the price will be about £1,600 to £2,000 plus VAT. Remember, you'll have to pay a bit more if you live in London.

Why remove & replace cavity wall insulation?

Mon, 24 Jan 2022 00:00:00 +0000

Getting cavity wall insulation is a proven way of keeping your home warm and cutting your energy bills. However, there are instances when the existing cavity wall insulation in a property needs to be removed or replaced. For example, it may have suffered damage over time or perhaps the insulation used originally wasn’t suitable for your home in the first place. In this article, we will look at the key reasons why homeowners may decide to remove and replace their cavity wall insulation.

Why would I need to remove my cavity wall insulation?

There are several reasons why you may need to consider having your existing cavity wall insulation removed and replaced, including:

Poorly installed insulation is now causing damp and or cold spots internally
The insulation has become defective or is unsuitable
The insulation has got wet due to the property being poorly maintained
The insulation has suffered water damage due to a flood or fire
A leaking roof has damaged it
The existing insulation has been infested by vermin

In the 1980s, building regulations stipulated that all new build properties should have cavity wall insulation as standard. However, once the rules were in force, it became clear there was a huge market for insulating older properties, an initiative that the government backed. As a result, many homes were targeted and sold cavity wall insulation regardless of suitability. We are now seeing some problems arise with early cavity wall insulation installs. Below we outline some of the most common issues we see as a result of these early installs:

Incorrect materials used

Early cavity wall installations used a material called urea-formaldehyde, which breaks down and releases formaldehyde into the home. In addition, as it breaks down, it falls into the cavity meaning higher walls are no longer insulated.

Incorrectly installed insulation

When the cavity wall installer puts the insulation in the wall cavity between the two skins of brick, the wall needs to be drilled in various places to allow even distribution of the insulating material. If the distances drilled are incorrect, the cavity would not be fully insulated and cause cold spots/damp problems.

Unsuitable for property

It wasn’t until new technology was developed that insulation suitable for all properties became available. Some older wall insulation types were found to cause dampness, especially in coastal areas where heavy rain and winds are expected.

Most people who come to us to enquire about cavity wall insulation removal have noticed a build-up of dampness in their homes. If you notice a problem like this, your cavity wall insulation may be the root cause. However, before going ahead with any work, we always recommend getting a professional to assess the problem as it could be caused by something else.

In addition, if you have noticed any signs of vermin (mice, rats etc.) living within your cavity walls, they could be causing damage to the insulation and making it ineffective. If substantial damage has been caused, it may be advisable to remove and replace the existing cavity wall insulation.

Finally, some customers come to us to replace their cavity wall insulation simply because they want it to work more effectively and drive down their energy bills. A professional will be able to carry out a home insulation assessment to determine if an upgrade to a higher-performing cavity wall insulation could benefit them.

Why insulate commercial buildings like schools, hospitals, and care homes?

Tue, 25 Jan 2022 00:00:00 +0000

Many of us know that we should insulate our homes to reduce our carbon footprint and lower our monthly energy bills.

But these benefits don’t just apply to domestic properties, we think insulation should be installed in commercial buildings – like schools, hospitals, and care homes – too.

There is a whole range of reasons why insulating buildings is one of the most sustainable and cost-effective things we can do.

Buildings that are thermally efficient are better for everyone. They’re more comfortable for the people who live, work or study in them, better for the environment and more affordable for the landlords/businesses that operate from them.

Here’s why we think all commercial buildings should be insulated.

It’s cost-effective

We all notice the energy bills in our homes going up when the weather gets cold, this is normally because without proper insulation, hot air escapes and we have to use more energy to keep our homes at a comfortable level.

Imagine how much heat is being lost in buildings as big as schools, hospitals, and care homes – a lot more than in a domestic property, that’s for sure.

Insulating these types of commercial buildings will result in significant cost savings as there won’t be as much reliance on energy and heating.

The money that can be saved on heating bills is far better spent on other parts of the business that can make a real difference for the people working, living and studying in these commercial spaces.

Buildings should be comfortable for their residents

Comfort should be the priority for any business, especially in places like hospitals, schools and care homes.

People expect the room temperature to be regulated, and for spaces to feel comfortable when they have to spend long periods of time in them.

The temperature has a big impact on people’s overall well-being, and through effective insulation, you can ensure that residents are as comfortable as possible – at all times.

Companies should be more sustainably conscious

In modern times, companies are expected to be socially and environmentally conscious. People want to work for eco-friendly businesses, and trust sustainable brands more than others.

By insulating their buildings, companies are making a big step towards reducing their carbon footprint and taking critical steps towards energy efficiency.

In these larger spaces, it’s even more important for people to take the environment into consideration when it comes to their building choices and strategies.

So whether these buildings install floor insulation, loft insulation, or just more efficient ventilation systems, it can make a big difference.

Five Warning Signs to Look Out for When House Hunting

Thu, 24 Feb 2022 00:00:00 +0000

When looking for a new house, you might be tempted to get swept up in the excitement of finding your dream property. But, if you opt for a house with problems such as dampness, the reality could come crashing down pretty quickly. Here’s our level-headed guide for what you should look out for when you’re hunting for that perfect property.

1. Poor Windows

We’re always told not to judge a book by its cover, but with houses, you can usually tell a great deal about the rest of the property from the state of the windows. If these haven’t been taken care of, it’s a good indicator that the rest of the house hasn’t been given the TLC it needs either.

2. Big cracks

Subsidence means that small cracks appear in a lot of houses over time. However, we’re not talking about a hairline crack here and there – if you see any large cracks anywhere in the property it could mean that it’s not structurally sound, and you could be landed with jobs that require a lot of time, work, and money to fix.

3. Foundation troubles

Similarly, problems with the foundation of your home can be a nightmare to repair. Inspect the foundation for cracks and bulges, as this can indicate that there are structural issues with the property.

4. Bad roofing

The roof of your home is extremely important, and a good, solid roof can last 30+ years. A poor one, however, can need replacing much sooner, with the time and money needed to carry out the job. Ask the seller how old the roof is, and have a look for yourself at parts of the roof you can see as well as the house’s gutter. And, if you’re serious about buying the house, get in a roofer to inspect its condition.

5. Signs of damp

If left untreated, dampness can be a huge problem for your house. Make sure you look closely for the signs – a strange smell, lack of ventilation, flaky plaster on the walls, watermarks on the walls or ceilings. You should even question the seller if a room has been recently painted as they may be trying to cover up the problem. Damp can be caused by several issues, including poor insulation throughout the home – so make sure you pay close attention to this one.

What Could be Causing Mould, Damp and Condensation in your Home?

Tue, 01 Mar 2022 00:00:00 +0000

If you’ve spotted the signs of mould, dampness or condensation within your home it’s vital that you address the issue straight away before the problem can cause any more damage. But there are many reasons why dampness occurs within buildings and identifying the cause can sometimes be difficult. Without knowing what is causing the issue the damp is likely to continue getting worse. This could have an impact on both your health and the structure of your home.

Lack of ventilation – We produce moisture in our homes all the time simply by breathing! Coupled with other everyday activities, such as cooking, taking a hot shower or drying clothing, the production of moisture increases quite rapidly. If your home isn’t adequately ventilated, it can lead to mould forming. Opening windows, using extractor fans or purchasing a dehumidifier can all help to reduce the moisture within the building.
High humidity – The higher the humidity within your home the more likely it is that dampness will form. Drying clothes indoors and cooking without using saucepan lids are just two examples of how daily routines can lead to more moisture within the home. In many cases, this can be tackled by improving ventilation.
Poorly installed cavity wall insulation – While cavity wall insulation should help to make your home warmer and more energy-efficient when it’s poorly installed, it can lead to water soaking into the insulation. With moisture held within the wall, it can quickly lead to damp and noticeable mould in the home.
Lack of building maintenance – Poorly maintained buildings can mean the risk of dampness, mould and condensation rising. From leaking pipes that lead to water pooling to missing roof tiles, keeping on top of your home’s maintenance can have a big impact. In many cases, it can be some time before these issues are spotted, such as if leaks are occurring within the walls, which can mean issues are already established and then harder to fix.
Water at the foundation – If the ground around your home slopes towards the building, it can lead to rainwater building up around the foundation and damp rising. If this is an issue your house is experiencing it’s likely you’ll need to add drains or landscape the ground so that water flows away from the building. Flooding can also cause a similar problem and an increase in mould forming.

If your property is suffering from penetrating dampness and mould, contact Extract Insulation to assess your existing cavity wall insulation. We will give you a free no-obligation survey.

The Guide to Tackling Damp in your Home

Fri, 04 Mar 2022 00:00:00 +0000

Damp in your home can not only look unsightly, but it can also have a negative impact on your health and affect the structure of the building. Whatever is causing the dampness, whether it’s cracks in the walls or poorly installed cavity wall insulation, tackling the issue as soon as possible is hugely important.

Assessing what is causing the dampness in your home is a good first step to tackling it. It will be impossible to rid your home of mould if this isn’t fixed. It could be as simple as clearing your gutters of blockages or you may need professional work doing, such as if you have missing tiles on your roof. As well as identifying the cause, there are plenty of steps you can take to reduce dampness within your home.

Regularly ventilate your rooms – Allowing air to freely move around can cut the chances of dampness occurring and help address the issue if it’s already caused mould. Rooms that are used regularly should be ventilated, leaving a window open for a while can help achieve this.
Dry clothes outdoors – Drying clothes indoors can increase the moisture within the home, leading to dampness. Where possible it’s a good idea to dry clothing and other items outdoors or if you use a tumble dryer to ensure the machine is properly ventilated.
Shut the doors – If you’re taking a hot shower or cooking shutting the doors between the rooms can prevent steam from entering colder rooms, which can then lead to condensation forming.
Use an extractor fan – If you have one, turning on an extractor fan can have a big impact on reducing dampness within your home. If dampness is a persistent issue in your house, installing an extractor fan in the kitchen and bathroom should be a step you consider.
Wipe down damp surfaces – Damp surfaces, such as window sills and kitchen counters after cooking, should be wiped down to get rid of the excess moisture.
Use a dehumidifier – Dehumidifiers draw the moisture out of the air and can be an excellent choice for properties that are not well ventilated or where damp and mould have already begun to form in certain rooms.
Pull furniture away from the walls – Trapping air between walls and furniture can lead to mould forming as the area isn’t well ventilated. Pulling furniture away from the walls slightly or placing it against internal walls, rather than external walls, can give ventilation within a room a boost.

If your property is suffering from penetrating dampness and mould, contact Extract Insulation to assess your existing cavity wall insulation. We will give you a free no-obligation survey.

What to Do When your Cavity Wall Insulation Fails

Mon, 07 Mar 2022 00:00:00 +0000

Cavity wall insulation should mean your home is kept warmer, reducing your energy bills and carbon footprint in the process. But if your installation has failed, it can lead to dampness in your home and the benefits not being felt. Knowing where to turn if your installation has failed can be difficult, but following our steps can help you get the issues resolved quickly and effectively.

It’s thought that thousands of homes across the UK have been affected by poorly installed insulation. However, the figure could be even higher as some of the defects remain hidden or are wrongly attributed to other factors. According to a survey conducted by thermal-imaging company IRT Surveys, as many as half of cavity wall insulations could be affected. The signs of cavity wall insulation failure could be as simple as noticing patches of dampness on external walls or could be recognising that the installation isn’t delivering the energy-saving benefits it should.

If you believe your cavity wall insulation installation has failed, either due to shoddy workmanship, the property being unsuitable or poor materials being used, these steps could help you:

Minimise the damage – If you notice dampness, condensation or another effect of poorly installed cavity wall insulation, you should seek to minimise the damage as soon as possible. This could involve ensuring the rooms are properly ventilated to reduce the risk of mould and using a dehumidifier to draw out moisture.
Contact CIGA – If you’re covered by the Cavity Insulation Guarantee Agency’s (CIGA) guarantee, you will be covered for 25 years after the insulation has been installed both for the materials and workmanship. The guarantee covers registered installers in the UK and Channel Islands. Contacting an independent agency could give you access to expertise and allow you to rectify the problem.
Extract the insulation – The insulation that has been installed within your walls can be removed, eliminating the root cause of the problem. Independent extractors, such as Extract Insulation, are often experienced in dealing with the problems poor quality or unsuitable cavity wall insulation has caused. They will be able to offer you advice and will understand the consequences it can have on your home.
Reach out to an alliance – The Cavity Wall Insulation Victims Alliance was formed by people that had suffered due to poor cavity wall insulation themselves. The alliance has been lobbying trading standards departments and MPs to support those affected by cavity wall insulations that have failed. The organisation can be contacted if you’re experiencing problems.

We at Extract Insulation have been working with a variety of customers to meet their insulation demands. If you're looking for peace of mind this winter, contact the UK's leading specialist in insulation removal for a free no-obligation survey.

Is your Home Suitable for Cavity Wall Insulation?

Thu, 10 Mar 2022 00:00:00 +0000

When you choose to have cavity wall insulation installed in your home, you should be able to rely on professional firms to offer you guidance. Unfortunately, this isn’t always the case and if your home isn’t suitable for the measure, it can lead to a whole raft of problems further down the line. This can be both time consuming and costly.

A survey conducted by Which? in 2011 proves that some cavity wall insulation firms are more focused on profit, recommending the energy-saving measure even when the property isn’t suitable. The consumer association asked eight separate firms to assess a house that was clearly unsuitable for cavity wall insulation and could have led to other negative effects, such as dampness within the home and cracks appearing in the walls if installed. Despite the unsuitability of the property, all the companies involved recommended cavity wall insulation.

If you’re considering cavity wall insulation, understanding whether or not your property is suitable can help you avoid installing an unsuitable solution.

Do you have cavity walls?

Obviously to have cavity wall insulation installed you need cavity walls. If your house was built after 1920 it’s likely to have cavity walls and unless it was built in the last two decades, these cavities are unlikely to be filled. If you’re unsure about your walls, you can tell by the brickwork: if the exposed bricks are all the same size, you have cavity walls.

Are the external walls accessible?

If your external walls are accessible, it makes it easier for the work to be conducted. While some installers may still be able to conduct the work even if this isn’t the case, it will add to the final cost.

How wide is the cavity in your wall?

The cavity between the two walls should be at least 50mm wide for cavity wall insulation to be installed.

Are your walls in good condition and internal walls dry?

Existing cracks, dampness or other issues with your home’s walls can be exacerbated by installing insulation. They can also cause the insulation to fail if damp gets into the cavity. Existing problems should be rectified before the work is undertaken.

Is your home regularly exposed to wind-driven rain?

Houses prone to dampness and that are regularly exposed to wind-driven rain are not suitable candidates for cavity wall insulation. There are some bad practices in the industry that means these unsuitable homes are being recommended for cavity wall insulation in some instances.

Does your home have steel or timber frames?

If your home has steel or timber frames, then cavities are needed to let moisture leave the building and the property is not suitable for cavity wall insulation.

If you need some expert advice, contact a professional to assess your existing cavity wall insulation. We at Extract Insulation will give you a free no-obligation survey.

Does the material for retrofitted cavity wall insulation matter?

Tue, 15 Mar 2022 00:00:00 +0000

When you choose to have cavity wall insulation installed in your home, there are a lot of different aspects the professionals should take into consideration, including the type of material they’ll use. Retrofitted cavity wall insulation that isn’t installed properly can cause long-term issues that the homeowner will need to resolve at a later date. These include damp and structural damage. Poorly selected material can have a serious negative impact.

Over the last 15 years, Extract Insulations has worked with many homeowners to remove their insulation as a result of it failing. Hence, we understand how the different material options can have an impact.

White wool – White wool fibre insulation is among the most commonly used materials for cavity wall insulation across the UK. In our experience, it’s also the material that is most likely to absorb and hold water, leading to unintended consequences, such as dampness and mould, and the need for it to be removed.

Yellow wool – Yellow wool is fibre insulation that was mostly blown during the 90s and isn’t installed as commonly now. Installers would use a nozzle to aim the insulation up and as the pressure increased it would blow the material left, right and, finally, downwards. While it’s used less now there are still examples of this insulation failing.

Rockwool – While all fibre insulation can cause problems, if this is the option you want, we’d recommend selecting Rockwool the majority of the time. While issues such as damp and cracked walls can still occur when Rockwool is used, in our experience it’s less likely to happen compared to white or yellow wool.

Bead insulation – Bead insulation is the option that we would recommend for homeowners considering cavity wall insulation. The material means that the beads bond together with PVA glue, creating insulation that is more robust and durable than other alternatives.

Urea-formaldehyde – This material often shrinks and deteriorates, meaning the benefits of cavity wall insulation aren’t felt for long by the homeowner. Those that have used urea-formaldehyde often find that it needs extracting and upgrading for a newer product if the property is suitable.

Polyurethane foam – At Extract Insulation, we wouldn’t recommend using polyurethane foam as it’s impossible to remove the insulation without also removing the wall should you encounter problems. The material is often used for homes in flood-prone areas.

If you need professional help to choose the cavity insulation that's right for you, contact us for a free, no-obligation survey. Extract Insulation has been working with a variety of customers to meet their insulation demands since 2013.

BRE shines a light on cavity wall insulation risks

Thu, 17 Mar 2022 00:00:00 +0000

The argument against poorly installed cavity wall insulation installations has been happening for years but a new report shines a light on how damaging the unintended consequences of the measure can be. A report looking at the impact cavity wall insulation has had on homes in Wales was conducted by the Building Research Establishment (BRE) and highlights some of the risks.

Focussing on homes across Wales that have been retrofitted with cavity wall or external wall insulation, the report indicates that thousands of homes could be negatively affected by the practice, including experiencing damp and cracked walls. The findings were enough for BRE to recommend that further surveys were undertaken to fully assess the scale of the problem and that steps are now taken to improve performance, promote best practices and share lessons learnt around ongoing refurbishment work.

It was found that many installations have been installed in unsuitable properties or without due regard for best practices in order to ensure that the insulation would provide the benefits to the dwellings it should. With over 900,000 homes in Wales having cavity walls and around half of these being insulated in 2008 it’s thought that the associated risks of cavity wall insulation can be affecting thousands of homes in the country.

BRE noted, “There is growing evidence which demonstrates that the industry has much work to do to improve the quality of site surveys and on-site workmanship. Furthermore, the industry needs to work with residents to educate and advise to support behaviour that avoids any unintended consequences of refurbishment, for example, poor ventilation leading to condensation, dampness and mould.”

The report builds on concerns raised by others and the growing number of homes that are choosing to have their insulation removed after experiencing problems. The number of homes affected could be much higher than estimates suggest, as many homeowners don’t realise what the root cause of their problem is, meaning they often mask the issue but don’t fully address it. For example, homeowners experiencing dampness may purchase a dehumidifier to remove the mould while not realising that it is their cavity wall insulation that is causing the problem.

The BRE findings highlight how important it is for homeowners to fully understand what cavity wall insulation involves and how to find an installer they can rely on to provide the correct recommendations and workmanship.

Top tips for insulating your home

Mon, 21 Mar 2022 00:00:00 +0000

The winter chill is biting. If you’re worried about your energy bill rising during the winter months, insulating your home could be a step to cutting them down. The UK’s set for a cold winter this year, with storms and snow already seen across the country. Many will be tempted to turn their heating up to keep the cold out of the home while they get cosy and watch their favourite TV shows, catch up with friends and family or simply relax. With some added insulation, however, you could avoid the extra heating costs.

Insulate your loft space – If you haven’t already, insulating your loft space could save you a significant amount on your energy bill. Heat rises and homes can lose up to a quarter of the heat produced through their roof. Adding insulation to the loft space can make sure your home stays warm throughout the year. While it does require an additional cost, it can last for decades. Over that time it will pay for itself many times over.

Consider wall insulation – Another quarter of your home’s heat is lost through the walls and floor. Insulation can be added to your walls, whether you have cavity or solid walls in your home. While it can save money, it’s vital to pick an installer that understands whether your home is suitable and adheres to best practices. Otherwise, you could face costly and time-consuming measures to rectify issues such as damp and cracked walls.

Think about your radiators – Radiator reflector panels are simply fixed behind radiators and will reflect heat from the radiator back into the room, ensuring you feel the benefit as much as possible. It’s a relatively low-cost option that homes with uninsulated walls can particularly benefit from.

Invest in windows – Plenty of heat can escape out of your windows even when they’re shut, especially if they are single-glazed. Double or triple-glazing can make a big impact and if you choose windows with insulation material between the glass and a seal around the trim it will be even more beneficial. Investing in your windows could mean saving in the long term.

Use your curtains and blinds – While the type of windows you choose has an impact, so do your curtains and blinds. Throughout the day open them up and let the sunlight in before shutting them during the evening to cut the amount of heat leaking out. Thicker curtains or blinds that are lined can give this method a further boost.

Have things changed since parliament debate on cavity wall insulation?

Fri, 25 Mar 2022 00:00:00 +0000

Issues around cavity wall insulation have been raised for years, particularly around companies installing it to owners of unsuitable homes. Last year parliament debated the issues and noted key concerns but have things changed since the problems were raised to better protect homeowners?

Cavity wall insulation can help save homeowners money, by ensuring that less heat escapes, cutting down energy and heating bills. It’s estimated that the cost of installing the insulation could repay itself on the savings made on bills alone in as little as nine months. Cavity wall insulation has been one of the government's key policies for reducing energy consumption and carbon emissions.

While the evidence does suggest that cavity wall insulation does have some benefits, it isn’t suitable for all buildings. For example, homes regularly exposed to wind-driven rain are not suitable as it can lead to the insulation becoming damp. As well as being unsuitable other issues can arise, such as voids in the cavity, companies wrongly installing the insulation and deterioration of the materials used.

In February 2015 cavity wall insulations were debated in parliament. During the debate it was noted that in 2011 Which? asked eight companies to assess a house that was clearly unsuitable for cavity wall insulation. Despite this, all of the surveys conducted by the companies involved recommended installing cavity wall insulation. The debate also noted that while a routine independent inspection of the properties after work has taken place is required by Ofgem, it takes place only a few weeks after installation when problems are likely to occur more than a year after the work has been completed. The inspection also checks whether energy reduction targets are being met, not whether there are damp problems.

Concerns were also raised that the Department of Energy and Climate Change was somewhat sweeping the issue under the rug for fears that acknowledging the problems would discredit a key energy conservation policy. Despite this, news of cavity wall insulation having problems is still discrediting the policy and suggestions have been made that all retrofitted cavity wall insulations could encounter problems further down the line.

While Parliament recognising the problem was welcomed news it hasn’t translated into action yet. This means that homeowners still risk being affected by problems in the industry if they don’t have the survey and work completed by a company offering the standard of service expected which could mean that the insulation needs to be removed further down the line.

If you need some expert advice, contact a professional to assess your existing cavity wall insulation. We at Extract Insulation will give you a free no-obligation survey.

Energy bill rising, are you struggling?

Tue, 29 Mar 2022 00:00:00 +0000

In October 2021, Ofgem increased the price cap to £1277 across the UK. For the average consumer, this means most people saw their energy bill rise by £139 a year or more if they were on a pre-payment meter. Following this, on 3 February 2022 Ofgem announced the default tariff cap to rise by an eyewatering 54% from 1 April 2022.

This has put pressure on many households. We’ve put together this article to cover why energy prices have risen so steeply and what to do if you are struggling.

Why are energy prices rising?

Put simply; it’s down to an increase in the wholesale gas prices that the energy suppliers pay. These costs have been rising quickly since Ofgem updated its price cap in December 2020. Gas prices reached record highs as the world came out of lockdown and other economic factors affected the rising costs. As a result of the steep price rises, over twenty smaller energy companies went bust because they couldn’t survive the volatile energy market and the substantial wholesale price hikes.

Unfortunately, for consumers, it meant that the price increases suffered by the energy companies are now being passed on to households through energy bills.

Will my energy bill go up?

According to Ofgem, consumers on a standard variable tariff are likely to see a price increase of around £139 per year. If you are lucky enough to be on a fixed deal, your bills won’t go up until your contract ends. Until recently, it was common practice for consumers to switch energy suppliers when their bills increased. However, now energy prices have reached record highs, there are no longer any cheap energy deals to be had. Ofgem’s advice right now is to stick with your current supplier.

Help if you are struggling

If you are struggling to pay your energy bill, it’s advisable to contact your supplier sooner rather than later. Your energy supplier has an obligation to help you develop a payment plan that works for you both. Additional support is also available for the vulnerable. For example, your supplier can advise you of any grants available and charities that may be able to help.

Other ways to reduce your energy bills

Energy price rises have affected the whole nation. One way to reduce your energy bills is to make your home more energy-efficient. This can be done in several ways:

Improve your insulation
Upgrade your appliances and boiler
Install solar panels and other renewable technology

There are grants available to help with the above energy efficiency home improvements. However, even without grants, they are still surprisingly affordable and can save you a substantial amount of money in the long run.

Can Insulation Improve Property Value?

Fri, 01 Apr 2022 00:00:00 +0000

The Office for Budget Responsibility predicts that house prices across the UK will experience a steep fall in the post-pandemic landscape, showing no signs of returning to 2021 levels any time soon. For homeowners considering selling their house in the future, this means exploring possible ways to maximise the value of the property to ensure they’re receiving the best offers from their potential buyers.

How to Boost Property Value

There are multiple ways to increase the value of a property, including updating older decor and designs, renovating the kitchen or bathroom, or adding an extension. However, many of these techniques require significant initial outgoings, making them unsuitable for those who are unable or not willing to invest heavily in upgrades.

One way to improve property value that is often overlooked by homeowners is simply to boost energy efficiency. The Energy Saving Trust estimates that energy costs for the average semi-detached home could be reduced by £185 per year with cavity wall insulation. Buyers are willing to pay more for an efficient property that reduces heat loss and ultimately saves them money in the long term.

Energy Efficiency & Property Prices

The reduced energy costs, coupled with a growing desire to purchase ‘green’ homes, means that properties with the highest energy performance certificate (EPC) rating are valued at up to £40,000 more than properties with lower energy ratings.

Research shows that improving from a G rating to an F rating can improve property value by 3.8%. Similarly, moving from the F band to the E band can boost value by 2.9%, from E-D by 2.4%, from D-C by 2%, from C-B by 2%, and from B-A by 1.8%.

The average property in England has a D rating, which means that most properties could increase in value by almost 6% by incorporating energy-efficient measures.

Why Insulate?

Of course, there are many different ways to improve the energy efficiency of a home, from replacing an old boiler to installing double glazing. However, reports suggest that insulation could be key to increasing an EPC rating. One London-based EPC assessment firm estimates that an uninsulated 3 bedroom end terrace could add 15 points to its rating with 200mm insulation, or 16 points with 400mm insulation.

Insulate Tight, Ventilate Right!

Mon, 04 Apr 2022 00:00:00 +0000

There’s a common saying in the construction world: Build tight, ventilate right. However, we think that’s something that rings true in the insulation industry, too. Insulating tight and ventilating right is the foundation of any good installation.

Insulate Tight

A common misconception in the insulation landscape is that a home can be ‘too tight’; that it can have too much insulation, making it overly airtight. But the truth is that, when it comes to properties, there’s really no such thing as being ‘too airtight’; airtight is what you’re aiming for. Ultimately, the tighter the insulation, the better!

After all, insulation with gaps, or under-packed insulation, is problematic. It’s not going to be able to reduce heat loss to the extent needed unless it’s super tight. And with reports showing that more than one-third of heat escapes through the walls, having tight cavity wall insulation is critical if you’re going to see the desired results.

However, it is true that tight insulation can cause problems when it’s not paired with the right ventilation. Buildings need to ‘breathe’; they need to allow for water vapour from cooking, bathing, and simply breathing, to escape. Otherwise, moisture can’t go anywhere; it’s left building up condensation, leading to dampness and mould. That’s why ventilation is so important.

Ventilate Right

Insulation, ventilation, and airtightness form a pyramid. And you can’t have one without the other. If you increase one - insulation - you increase another by default: airtightness. So, you can’t afford to leave the other part of the triangle lagging behind; you must be prepared to boost ventilation with any new installation.

Unfortunately, many homes - especially older homes - don’t have adequate ventilation for the tight insulation that’s being retrofitted. So much so that the Committee on Climate Change is asking for ‘regulations around ventilation to evolve to keep pace with improvements in the energy efficiency of buildings'.

Ventilation Options

Fortunately, there are many options available for improving ventilation in tightly insulated homes. This includes natural ventilation techniques, such as airing rooms regularly by opening doors and windows, to mechanical ventilation options such as extractor fans in kitchens and bathrooms. There’s also the option to add air bricks, air vents, window vents, and roof ventilation tiles to enable improved airflow.

Do you still have questions about airtightness and ventilation? We’re here to answer them! Get in touch to find out more about insulating tight and ventilating right!

The Importance of Maintaining Your Property After Cavity Wall Insulation

Wed, 06 Apr 2022 00:00:00 +0000

Government estimations suggest that up to one-quarter of UK homeowners with retrofitted cavity wall insulation could experience problems with the installation in the future. In many cases, poor workmanship will be responsible for the issues. However, we need to remember that poor property maintenance won’t help.

Why Cavity Walls Experience Problems

The most common concern with cavity wall insulation is that moisture will cross the gap and cause dampness and mould to form inside a property. The main reason for this to happen is shoddy work. Maybe a cavity is underfilled, with the insulation carrying water from one side or another. Or perhaps the cavity hasn’t been cleared thoroughly, with leftover debris creating a link from the external to internal walls.

However, the quality of the installation isn’t always the main culprit. Even with the highest standards, the most skilled professionals, and the best materials, the homeowner must always ensure they’re properly maintaining their property after the installation.

Property Maintenance & Insulation Efficiency

External walls that are exposed to wind-driven rain can significantly affect the performance of cavity wall insulation. Any cracks or vulnerabilities in the external brickwork or rendering can allow directional water jets to penetrate the outer wall, increasing the likelihood of moisture transfer across the cavity to the inner walls. Maintaining the exterior walls of the property is essential following an installation.

Another factor to consider is condensation. While the insulated walls themselves will feel warm, surrounding uninsulated areas will feel cold. This means that, should there be a lot of water vapour in the air, this can hit the cold walls and produce condensation which then becomes a risk factor for dampness around the cavity walls.

Following an installation, you should ensure that any kitchen extractors, bathroom fans, or other forms of ventilation are working well to minimise a vapour build-up.

What Happens if a Property Isn’t Maintained?

Without regular maintenance, it’s possible that dampness and mould could form inside the property. This brings with it its own set of problems, such as a loss of structural integrity, challenges in selling a property, and even health concerns. Not only will this require treatment of the mould and dampness, but also a removal of the compromised insulation inside the cavity wall, and the complete replacement of the insulation.

At Extract Insulation, we’re here to remove damp insulation and provide a new installation as needed. However, prevention is always better than cure. Get in touch for more advice on maintaining your property to get the most from your insulation.

Will a Mortgage Provider Lend on an Uninsulated House?

Mon, 11 Apr 2022 00:00:00 +0000

If you’ve got your heart set on a certain property, but it’s currently uninsulated, you may be wondering whether or not you’d be able to secure a mortgage to buy it.

Will a lender provide a mortgage on an uninsulated home? The simple answer is ‘yes’, although you should be aware that the number of lenders willing to do so is dropping rapidly as more and more embrace the concept of ‘green’ mortgages.

A Shift to ‘Green’ Mortgages?

Not all providers will agree to lend on an uninsulated home. In fact, it’s reported that upwards of 90% of lenders consider energy consumption when making a decision. And it’s easy to see why, with a Bank of England study showing that payments on homes with a lower EPC rating are more likely to be in arrears than payments on more energy-efficient homes. This is sparking a shift towards ‘green’ mortgages.

Green mortgages are mortgages that are tied to energy efficiency. The concept behind them is that those living in more energy-efficient homes will spend less on energy bills, thereby lowering their outgoings and making them a more attractive investment. Green mortgages may have lower rates than a standard mortgage or benefits such as additional lending opportunities for energy efficiency upgrades.

Government Goals

It is expected that lending on uninsulated homes and homes with poor energy efficiency will reduce even further following a recent announcement by the Government that mortgage providers will be expected to play a role in helping the country edge closer towards its goal of achieving net-zero emissions by 2050.

‘Mortgage lenders could play a vital role in driving the home energy performance improvements required to meet our Carbon Budgets and net-zero target. They are uniquely placed to influence mortgagors at critical trigger points, such as home purchase, renovation or re-mortgage’, notes a 2021 report.

What to Look Out For

It’s important to remember that not all insulation was created equal, and that even if the property appears to be insulated, it may still be difficult - if not impossible - to secure a mortgage on some types of property. In fact, it has been suggested that up to 250,000 UK homes may be unmortgageable because of older spray foam loft insulation that is now understood to affect the structural integrity of a building.

Lenders like Aviva already consider this to be ‘not acceptable’ for consideration.

It is widely being recommended that spray foam loft insulation is removed prior to listing a property for sale, removing obstacles that could emerge later in the sales process. At Extract Insulation, we offer efficient removal and clearing services, leaving your space ready for a new installation and maximising its value to potential buyers.

Is having cavity wall insulation worth it?

Thu, 14 Apr 2022 00:00:00 +0000

If your house was built after the 1920s, you may have cavity walls. This is where there are two brick walls with a gap in the middle.

Although they’re commonly found in homes, they’re actually one of the leading causes of energy inefficiency in domestic properties. In fact, they are often responsible for up to ⅓ of heat loss in uninsulated houses.

The more heat loss that you experience in the house, the more energy you’ll have to use heating your space to keep you and your family warm and comfortable – which can lead to significant increases in your monthly energy bills.

To avoid this heat loss and keep your energy bills down, one of the simplest things you can do is pay a professional to install cavity wall insulation.

How does cavity wall insulation work?

A specialist approved contractor can easily install cavity wall insulation with minimal disruption to your home.

They will simply inject either polystyrene beads, mineral wool or rock wool into the cavity through small, drilled holes. After, the holes will be filled in with cement mortar.

How much does cavity wall insulation cost?

It will normally cost around £12 per m2 to install cavity wall insulation, which amounts to between £800 and £1200 for the typical three-bedroom property.

What are the benefits of cavity wall insulation?

There are many benefits that come with installing cavity wall insulation, but here are some of the most important:

It’s a cheap energy-saving method

Compared to other energy-saving methods, the cost of this type of insulation is relatively cheap.

Quick and simple to install

The process of getting a professional to install your insulation is incredibly quick and simple.

Get in touch with us today to see how long it would take Extract Insulation to install this in your home.

Long-lasting solution

On average, cavity wall insulation should last you from 25 years.

If you get your insulation installed by a registered installer, you’ll also benefit from a 25-year guarantee, so its maintenance is not something you have to constantly keep in your mind.

Keeps your home warmer and more comfortable

Cavity wall insulation prevents air from escaping out of your walls, which keeps your home at a more comfortable temperature – even when it’s icy cold outside.

Reduces your energy bills significantly

Depending on the size of your house, you could be looking at saving between £150–£350 a year, quickly making back the initial cost that you paid for the insulation.

So, looking at how much it costs to install cavity wall insulation and all the benefits you can enjoy as a result of it – yes, having cavity wall insulation is definitely worth it!

Who are retrofit coordinators and assessors?

Mon, 18 Apr 2022 00:00:00 +0000

The UK has recently started to become more serious when it comes to making our homes and buildings more eco-friendly.

In an effort to meet global carbon emission reduction commitments, the Government has begun the process of tackling the issues of domestic and commercial retrofit. This is where new technology and systems are added to existing, older properties to make them more efficient and sustainable.

In defining the new retrofit process in the UK, which is governed by PAS 2035, the regulations identified several key roles that are crucial in any retrofit process.

Two of the most important roles are retrofit coordinators and retrofit assessors. Here’s everything you need to know about these two roles:

Retrofit coordinators

In order to comply with the PAS 2035 regulations, a retrofit coordinator is required on all domestic retrofit projects.

These people will play an important project management role and will work to ensure that the project protects both the clients and the public.

They will be involved in the retrofit project at all stages, from the time that the project starts to take form, up to when it is finally completed. This will include organising building owners, and other stakeholders to ensure that the project runs smoothly and effectively.

Retrofit assessors

Retrofit assessors are also required to be part of the retrofit purpose under the PAS 2035 regulations. They are trained professionals who will perform a retrofit assessment for the project.

This assessment will include things like a RDSAP assessment, a detailed floor plan, a condition report, and an occupancy assessment.

The retrofit assessor will then pass this information on to the retrofit coordinator for the project, this will feed into their Medium-Term Improvement Plan.

Six-stage process of a retrofit project

The retrofit assessor and coordinator are both crucial parts of any retrofit project which, under the PAS 2035 regulations, is a six-stage process that’s made up of the following steps:

Intended outcomes
Risk assessment
Whole Dwelling Assessment
Design and coordination
Installation
Monitoring and evaluating

Professional contractors

At Extract Insulation, we’re trusted contractors that can help you with your retrofit project.

With expert insulation installation services, we can help you transform homes and commercial properties into spaces that are more environmentally friendly and cost-effective.

Why insulate commercial buildings like schools, hospitals and care homes?

Thu, 21 Apr 2022 00:00:00 +0000

Many of us know that we should insulate our homes to reduce our carbon footprint and lower our monthly energy bills. But these benefits don’t just apply to domestic properties, we think insulation should be installed in commercial buildings – like schools, hospitals, and care homes – too.

There is a whole range of reasons why insulating buildings is one of the most sustainable and cost-effective things we can do.

Here’s why we think all commercial buildings should be insulated.

It’s cost-effective

Imagine how much air is being lost in buildings as big as schools, hospitals and care homes – a lot more than in a domestic property, that’s for sure.

Insulating these types of commercial buildings will result in significant cost savings as there won’t be as much reliance on energy and heating.

The money that can be saved on heating bills is far better spent on other parts of the business that can make a real difference for the people working, living and studying in these commercial spaces.

Buildings should be comfortable for their residents

Comfort should be the priority for any business, especially in places like hospitals, schools and care homes.

People expect the room temperature to be regulated, and for spaces to feel comfortable when they have to spend long periods of time in them.

The temperature has a big impact on people’s overall well-being, and through effective insulation, you can ensure that residents are as comfortable as possible – at all times.

Companies should be more sustainably conscious

In modern times, companies are expected to be socially and environmentally conscious. People want to work for eco-friendly businesses, and trust sustainable brands more than others.

By insulating their buildings, companies are making a big step towards reducing their carbon footprint and taking critical steps towards energy efficiency.

In these larger spaces, it’s even more important for people to take the environment into consideration when it comes to their building choices and strategies.

So whether these buildings install floor insulation, loft insulation, or just more efficient ventilation systems, it can make a big difference.

What are the best ways to insulate a house?

Insulating your home is one of the most efficient ways to keep your energy bills as low as possible and reduce your home’s carbon footprint. Insulation helps to keep the cosy, warm air inside your house while keeping the cold air where it should be – outside.

Incorporating simple fixes around your home can rack up some pretty significant savings, but, you’re in safe hands with us!

We can help you with a number of jobs around the house using industry-leading equipment, professionals who know how and affordable insulation options.

Here are some of the best ways that you could insulate a house.

Cavity wall insulation

Did you know that almost a third of all the heat that’s lost in an insulated home escapes through the walls? A common issue comes from cavity walls, typical in buildings post-1920 where there are two walls and a gap in between.

These types of walls can be insulated by injecting cavity wall insulation material into the cavity from the outside. It only takes a couple of hours for a professional to complete this task but could reduce your monthly heating bills by 35%.

Using tested, premium materials we’re able to deliver long-lasting results that will help save you money for years to come.

Loft insulation

Investing in good quality loft insulation is another foolproof way to reduce your energy bills and reduce heat loss.

It’s one of the simplest yet effective ways to make your property more efficient, which can end up saving you thousands of pounds – more than making up for the initial investment.

As long as your loft doesn’t have any dampness, and is easy to access, there should be no issues with installing your insulation.

Floor insulation

Finally, we recommend investing in floor insulation. This is a great way to keep your property warm, even on the coldest winter days.

Although you generally only need to insulate the ground floor of your house, if there are any floors that are above unheated spaces – like a garage – you should consider insulating these too.

Using materials like mineral wool, rigid boards or foam, professionals are able to install the insulation to your house at the appropriate thickness for your room.

All your insulation needs

At Extract Insulation, we’ve been working in the industry for years, so we’re able to give professional advice and solutions to all your insulation needs.

Whether you need previous insulation removed, or brand-new material installed – you can come to us with whatever you need.

Why upgrade your heating system

Fri, 13 May 2022 00:00:00 +0000

Many properties still use older style heating and boiler systems. While the thought of completely replacing your heating system may seem costly and daunting, it’s well worth upgrading to more modern technology. Not sure why? Simple. To save money.

Older systems are less efficient, which means your present boiler or central heating could be costing you a lot more than you would like. Especially over the cold winter months when your heating is likely to be running day and night. Replacing a heating system is a substantial investment. However, the benefits of upgrading far outweigh the costs and here's why:

Less frequent repairs and maintenance

One of the tell tale signs it’s time to upgrade your heating system is when you encounter frequent problems. If you have to call out a professional on a regular basis to fix ongoing or numerous issues, the cost can soon add up. It will be more cost-effective to get a new system installed in the long term instead of forking out for more unexpected repairs.

Better energy efficiency

The initial cost of getting a new boiler installed is often a barrier many people can’t get over. In truth, the savings you’ll make by investing in a new boiler will far outweigh your initial outlay. New boilers are more energy efficient. Therefore, they cost a lot less to run than an older style heating system. For families looking to reduce their utility bills, installing a new boiler could significantly reduce energy costs

You’ll have much better control

Smart technology has revolutionalised how we heat our homes. You can now control heating levels in different rooms or turn on your heating on the way home from work. (More importantly, you can also turn it off if you forget to do so before you leave)! Modulating room controls, outdoor sensors, and thermostatic radiator valves all help improve the energy efficiency of your home.

New boilers are quieter

Only boiler systems are large, clunky and take up a lot of space. Take a look at a new system, and you’ll find that they are quieter, smaller and generally more attractive than the older style you are used to.

Help the environment

Are you interested in doing your bit to tackle climate change? Older boiler systems are renowned for wasting lots of energy. Upgrading to a newer, energy-efficient model will help you reduce your carbon footprint. In addition, if you combine your new heating system with high-performance cavity wall insulation, less heat will escape into the atmosphere, keeping you warm and your CO2 emissions down.
