We are busy with Cavity Wall Insulation Removal presently. There were many under performing products used when the insulation was been done for free through grants and older materials that have degraded that we remove. Some of these are causing damp, others are simply not keeping the home warm. In some cases, after a home has received new windows and doors, or had an extension built, the insulation is lost, leaving voids in the cavity.
In all these cases, we can remove the insulation from the wall cavity and replace it again with Thermabead.
