Cavity Wall Insulation Extraction
Say goodbye to old or insufficient insulation and make way for greater energy efficiency.
What is cavity wall insulation extraction?
Cavity wall insulation extraction is the process of removing insulation materials that have been installed within the cavity walls of your home.

Green benefits of cavity wall extraction + new insulation:
Greater energy efficiency
Cavity wall insulation boosts your energy efficiency and helps prevent up to 35% of heat escaping from your home. Good news for your comfort levels and your energy bills.
Lower carbon footprint
Improving your energy efficiency also means reducing your carbon footprint. Cavity wall insulation can help your home cut carbon emissions by up to 1.5 tonnes per year.
Enhanced air quality
Insulation eliminates damp, mould and condensation from your home. With proper ventilation, you’ll benefit from fresh air free of harmful pollutants and lingering odours.
Boosting renewable energy performance
A well insulated home allows renewable energy systems such as heat pumps and solar PV to last longer and perform at their best. That means even more money back in your pocket, plus greater gains for the environment.
