Our insulation experts use specialist equipment to safely extract and remove the old insulation material.
Cavity wall insulation removal
Why consider cavity wall insulation removal?
Cavity insulation removal may be necessary for several reasons:
- Poor installation – Inadequate pre-installation surveys can lead to poorly installed cavity wall insulation. This can result in gaps, rubble in the cavity, and water penetration causing damp and condensation issues.
- Lack of property maintenance – Failure to maintain a property after cavity wall insulation installation can lead to moisture buildup, causing internal wall damage.
- Building modifications – Careless renovations, like putting in boiler flues or windows, can bring debris into the cavity. This can damage the insulation which may create a thermal bridge, leading to condensation and damp issues.
- New wall ties – Cavity wall insulation removal is essential before installing new wall ties.
- Pest infestations – Vermin can contaminate cavity wall insulation and create voids as well as cause bad smells. The only solution here is cavity insulation extraction. This prepares the area for new, clean insulation
- Outdated insulation materials – Older insulation materials, such as Urea Formaldehyde Foam, can degrade, leading to damp and condensation issues. In such cases, cavity wall insulation removal ensures the installation of more effective modern materials.
Cavity wall extraction process
Professional cavity insulation extraction follows key steps to ensure minimal disruption:
- Survey and assessment – A thorough inspection determines the condition of existing insulation and identifies problem areas.
- Drilling access points – Our qualified installers drill small holes in the outside walls to reach the cavity. They will carefully take out bricks and save them for later reinstatement.
- Vacuum extraction – Professional, industrial-grade vacuum equipment is used to safely remove all insulation material, preventing further damp and condensation issues.
- Cavity inspection – The cavity is inspected to confirm complete removal of insulation and debris.
- Reinstallation of bricks – Bricks are replaced and drill holes are filled with closely matching mortar.
