How we work?

Upon arrival, a member of the team surveys your property and assesses the type of insulation installed. 

There are three common types of cavity wall insulation: blown-in insulation (sometimes called cellulose insulation), polystyrene insulation, and urea formaldehyde foam insulation. 

Once your insulation expert has established the type of insulation they’re dealing with, the removal team prepares the area by setting up protective barriers to minimise dust and debris. 

The cavity wall extraction team will then create an access point on the external walls (if there isn’t already) and insert a specialised industrial vacuum inside the cavity. 

Upon turning on the machine, the industrial vacuum collects the loose insulation material from inside the cavity wall. 

The loose material will travel to the collection point, where it’s bagged and later removed. 

If your insulation specialists encounter obstructions in the cavity, such as piping or wiring, they will carefully navigate around them to ensure safe and thorough removal. 

In rare cases, the installer might temporarily have to move or adjust this obstruction. It entirely depends on how these obstructions are positioned and installed.

After the extraction, any holes that were made in the inner and outer walls of the home will be sealed with cement and painted over to match your home’s exterior finish. Your installer should then clean the work area and remove any remaining debris or particles. 

Before extraction is complete, a final inspection ought to be carried out to ensure that the cavity is clean and ready for any necessary repairs or re-insulation.
