Cavity Wall Insulation is an effective way of insulating your property – but it can go wrong if the property has been incorrectly surveyed and then installed.
Unfortunately, a badly installed cavity wall can cause damp issues and other problems in the property and if there were existing issues it can make the problem much, much worse. The Cavity Wall Clearance process removes not only old and failed insulation, but also rubble, sand or debris that has built up within the cavity.
We have specialist equipment that forces insulation and debris to specific points in the walls from where we extract the material. We have industrial air compressors with high pressure nozzles and bespoke extraction vacuums that collects the waste materials ready to be disposed of properly.
Poorly installed Cavity Wall Insulation causes:
- Damp, mould and condensation.
- Causes or increases structural problems such as wall damage.
These problems then cause a knock–on effect that can:
- Reduce the value of your property.
- Affect your health.
If you have existing damp or mould issues then there is the potential that this will be because of badly installed cavity wall insulation and your property may need to be assessed for a Cavity Wall Clearance
During our visit if we believe that damp or mould issues are due to bad cavity wall or that bad cavity wall insulation has made matters worse, we can carry out a specialist survey to try and establish this. We will locate areas of concern within the wall and use special cameras to look around to see what problems there may be.
If problems are found then a recommendation will be made in our Home Improvement Plan to carry out a Cavity Wall Clearance. The work involved can vary, in very extreme cases we would need to carry out multiple repairs to the wall externally and internally which may involve other works including; –
- New D.P.C. injection.
- Partial or full house re-pointing of mortar between brickwork.
- Damaged, frost damaged or flaky brick replacement.
- Gutters and drains cleared, repaired or replaced.
- Debris removal from the cavity wall.
- Sealing of or opening of existing vents – on a room by room basis.
- Removal of all existing cavity wall insulation.
- Mould treatment.
- Damp treatment.
- Removal and replacement of internal wall coverings including plaster and wallpaper.
- Removal of fixed/fitted storage such as kitchen units and cupboards.
- New mechanical ventilation systems.
Work of this nature is extensive and it is rare that our customers require all of the works above. Times vary from property to property and the extent of the damage; Cavity Wall Clearance work takes approximately 1-2 days to complete. Other essential works will increase this depending on the severity.
