HOW DOES CAVITY WALL INSULATION EXTRACTION WORK?
We use the latest specialist tools and machinery and have a team of insulation extraction experts that can extract defective cavity wall insulation, causing little disruption to the fabric of the building or to the occupier of the home. Our Insulation extraction specialists can undertake the extraction of all types of insulation products from the cavity walls of all types of building.
WHY EXTRACT CAVITY WALL INSULATION?
The cavity wall insulation extraction process is carried out for a number of reasons including:
- Defective cavity insulation material (such as Urea-formaldehyde) can break-down and release toxic gasses. Early foam insulation had this risk and was not covered by the same stringent BBA certification licenses or given the same 30 year guarantee through the Cavity Insulation Guarantee Agency (CIGA) as modern insulation materials.
- The cavity insulation gets wet, which breaks down the properties of the insulation. This can happen due to a number of reasons such as flooding, porous brickwork or mortar, or through a burst pipe in the attic.
- Poorly installed cavity wall insulation, installed with an incorrect drilling pattern or at the wrong density, can result in damp and condensation issues.

THE PROCESS OF CAVITY WALL INSULATION EXTRACTION
The defective cavity wall insulation material is removed as unobtrusively and cleanly as possible. Compressed air is blown into the cavity while an industrial vacuum collects the damaged insulation from the bottom of the wall through strategically removed bricks. A borescope is used to inspect the cavity throughout the process to ensure all damaged insulation has been completely removed. The old insulation is then bagged up and removed, while all the brickwork is made good.
The cavity wall insulation extraction process will take two days to complete in an average three-bedroom detached property. Once your defective cavity wall insulation has been extracted we can, if required, replace it with new cavity wall insulation.
Below is a list of materials that can be extracted from cavity walls:
- Expanded polystyrene
- Loose and/or bonded Urea Formaldehyde Insulation
- Rockwool Mineral Fibre
- Whitewool Glass Mineral Fibre
