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
