How do we remove failed insulation?

Following an initial inspection, if defects are found, a team will arrive on site and following their risk assessments will proceed to drill out the property. It will be drilled in a specialist pattern using original holes where possible. It will be necessary to open up vents and remove bricks at designated spots just above damp course level to allow exit points for the insulation to be removed.

Through the holes that are drilled, the operatives will drive compressed air through a rubber agitating whip and directional nozzle to break up and move the material to the exit points opened up.

An industrial vacuum then collects the material from the exit points and the operatives will work in a set pattern to move through the cavity ensuring that the material is removed.

The bricks are then replaced or vents installed dependent on our customers requirements

Why remove cavity wall insulation?

Removing cavity wall insulation is a complex process and should only be done by qualified professionals. They can assess the situation, determine if removal is essential, and then safely remove the material using specialised equipment.

In most cases, you would actually want to keep cavity wall insulation! It offers significant benefits for your home.

However, there are a few rare situations where removing it might be necessary. Here are the main reasons:

Improper Installation:

If the cavity wall insulation is installed incorrectly, it can trap moisture and lead to dampness, mould growth, or even damage the walls. In this case, removing and re-installing the insulation correctly would be necessary.

Unsuitable Property:

Certain types of properties, like timber-framed buildings, can be damaged by cavity wall insulation as it can trap moisture they need to release.

Defective Material:

Older insulation materials, particularly urea-formaldehyde foam used in the 70s and 80s, can break down and release harmful gases. If you suspect this type of insulation is present, it should be removed and replaced with a safe alternative.

Fire or Flood Damage:

If your home experiences fire or flood damage, the insulation may become saturated and need to be removed and replaced as part of the restoration process.
