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.
