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?
Hiring a certified cavity wall insulation removal company 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 your 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 cause debris to fall 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 the material, create voids, and cause bad smells. The only solution here is cavity wall insulation extraction which prepares the area for new, clean insulation.
- Outdated insulation materials: Older insulation materials, such as urea formaldehyde foam, can degrade. In such cases, cavity wall insulation extraction ensures the installation of more effective modern materials.
Our cavity wall insulation extraction process
As a certified cavity wall insulation removal company, we follow several key processes and procedures to make sure there is minimal disruption to your home.
Our surveyor will have already carried out a quick assessment of the cavity walls to determine the condition of the existing insulation and identify any problem areas. Once our installation team arrives, they will drill small holes in the outside walls to enter the cavity. These holes are used for air injection which forces the insulation to the extraction points.
After creating these holes, the team will also carefully take out bricks by using a saw, specifically designed for brick removal, close to DPC (damp proof course) level – these are the extraction points. The bricks will then be saved for later reinstatement.
After all preparatory steps have been completed, they will use professional, industrial-grade vacuum equipment and air to safely extract all insulation material from the wall cavity. The cavity is then thoroughly inspected to confirm the complete removal of the old insulation.
To finalise the process, your installation team will reinstate the bricks that were previously taken out and fill the drill holes with mortar of a similar type and colour.
