Cavity wall insulation can be highly effective when installed correctly. However, when the wrong material is used, it is installed poorly, or it becomes wet and degraded, it can cause serious problems including damp, mould, cold spots and even structural issues.
At Extract Insulation we specialise in the safe, thorough extraction of failed cavity wall insulation across Hampshire and the South of England. With over 20 years of experience and our own purpose-built Extract Vac machines, we remove defective material cleanly and efficiently, leaving the cavity ready for modern insulation or simply clear.
