We begin by understanding the issues affecting your property, whether that is damp, mould, condensation, cold spots or concerns around failed cavity wall insulation. This helps us assess the likely cause and recommend the right next step.
Using the correct equipment and proven methods, we safely remove failed cavity wall insulation from the property. The aim is to remove the problematic material thoroughly while keeping disruption to a minimum.
Once the insulation has been extracted, the cavity is checked to ensure it has been cleared as effectively as possible. This is an important part of the process, helping confirm that leftover material is not continuing to cause problems.
After extraction, drilled access points are carefully filled and made good. We can also offer further advice on protecting the property, improving performance and deciding whether any additional work may be needed.

Have questions about failed cavity wall insulation or the extraction process? Here are some of the most common things homeowners ask when dealing with damp insulation, mould, cold spots and related property issues.
Cavity wall insulation extraction is the process of removing failed, damp or unsuitable insulation from within the wall cavity using specialist equipment. This helps address problems such as damp, mould, condensation and poor wall performance.
Common signs include damp patches on internal walls, black mould, peeling wallpaper, musty smells, cold spots and increased heating bills. In some cases, a professional survey is needed to confirm whether the insulation is causing the issue.
Yes. If cavity wall insulation becomes damp or has been installed incorrectly, it can trap moisture within the wall and contribute to damp problems inside the home.
Failure can happen for several reasons, including poor installation, unsuitable property conditions, exposure to driving rain, blocked airflow, penetrating damp or insulation that has slumped over time.
In many cases, yes. Different insulation materials can require different extraction methods, so the best approach depends on the type of insulation installed and the condition it is in.
