Cavity Wall Extraction

If a cavity that has been installed incorrectly may result in there being severe effects on the property causing complications such as damp.

Debris and materials such as sand can gather at the bottom of the cavity and allow moisture to penetrate through the walls showing signs of damp or mildew.

In some circumstances you may have received some advice from your insurance company identifying that the insulation needs removing as soon as possible due to the risk of flooding, fire or any impact damage. Such risks may cause serious damage to the structure of your house which can cause irreversible damage. 

The specially trained extraction team at Renew Energies Ltd will use industry standard, and specific equipment to remove the insulation by using high pressure to push and move the debris into an extraction point. 

Our team of highly trained professionals will carry out the cavity wall insulation extraction with minimal fuss. We pride ourselves on a job well done, and completed to our high standards. We always make sure that the area we work in is clean and tidy once we finish. Our main focus is that you as the customer are completely satisfied with our service and remain stress-free throughout our work on the project.
