Cavity wall extraction refers to the process of removing material from the gap (or cavity) between the two layers of a cavity wall, typically in buildings with external walls consisting of two layers, a brick outer layer, and an inner block or brick layer.

The Outcome:

Frequently Asked Questions

How do I know if my cavity wall insulation needs to be removed?

Cavity wall insulation may need to be extracted if it has become damp, poorly installed, contaminated, or is causing issues such as mould, condensation, or cold spots. Properties exposed to driving rain or with older insulation materials are particularly at risk. We carry out professional assessments to determine whether removal is necessary.

Can cavity wall insulation be reinstalled after extraction?

Yes. Once the cavity has been fully cleaned, dried, and assessed, we can install a suitable, modern cavity wall insulation system where appropriate. We only recommend reinstallation when the property is suitable and the correct insulation type can be used safely.

How long do the works take?

Timescales depend on the service and size of the property. Many insulation and remedial works can be completed within one to three days, while roofing projects may take longer. We always provide clear timescales before work begins.
