Cavity Wall Insulation Removal

Initial Enquiry & Assessment

We start by discussing the issues you are experiencing — whether that's damp patches, mould growth, condensation, cold spots or general concerns about your existing cavity wall insulation. This helps us understand the property and advise on the most suitable next step.

Inspection & Free Quote

Once we have an idea of the problem, we carry out a full inspection of the property and assess the condition of the cavity wall insulation, often using a borescope camera. From there we provide honest advice, explain our findings clearly and offer a free, no-obligation quote for the recommended work.

Specialist Extraction

Using the correct equipment and proven methods, we carry out the safe extraction of failed cavity wall insulation — whether that's blown mineral fibre, polystyrene bead or urea formaldehyde foam. Our aim is to remove the problematic material thoroughly while keeping disruption to a minimum and maintaining high standards throughout the work.

Making Good & Next Steps

After extraction, all access points are carefully filled and made good to match the surrounding brickwork. We then provide guidance on any recommended next steps — including repointing, waterproofing or re-insulation — helping you protect the property and move forward with greater peace of mind.

Signs Your Cavity Wall Insulation May Have Failed

• Damp patches or tide marks on internal walls, particularly on exposed elevations.
• Black mould growth around windows, in corners or on cold external walls.
• Persistent condensation on walls and windows.
• Cold spots and higher-than-expected heating bills.
• A musty smell inside the property that won't shift.
• Insulation was installed more than 10–15 years ago and has never been checked.
