Why Should I get Cavity Wall Insulation?

In most cases, the cost to you will be as little as a couple of hundred pounds. So, with your new annual energy savings, any cost of insulation will have paid for itself within 1 or 2 years. However, the cavity wall insulation grants provided by the Government through various energy companies means that there may be no cost at all to eligible homeowners throughout the UK. Westville can help access this funding directly to help minimise or even completely cover your cavity wall insulation cost. Contact us to find out if you qualify.

One of our fully trained installers will drill small holes in the outside wall of your home. They will then blow the specialised insulation product into your property cavity using our special equipment (see images above). Once your walls have been filled with insulation, we will fill in the holes in your brickwork, leaving you barely able to notice them. We can often get the job done in around 2 hours depending on the size of your property and all of our installers are fully trained as part of our customer care policy to insure any mess made is cleaned up, leaving your property as you would expect….spotless.
