Using specialist tools and machinery, North West Insulation & Extractions can extract ineffective cavity wall insulation, causing little disturbance to the fabric of the building or to the occupant of the home. North West Insulation & Extractions can undertake the extraction of Rockwool, White wool, foam and bead insulation products from the cavity walls of domestic and commercial properties.

This cavity wall extraction process is carried out for a number of reasons including:


The cavity insulation gets wet, which breaks down the properties of the insulation. This can happen due to a number of reasons such as flooding, porous brickwork or mortar, or through a burst pipe in the attic.


Poorly installed cavity wall insulation, installed with an incorrect drilling pattern or at the wrong density can result in damp and condensation issues.
