Cavity Wall Installation


Save up to 30% on heat bills

Reduce your carbon footprint

Improve comfort of your home

What is cavity wall insulation? If your home has a cavity wall a series of small holes are drilled in the wall, at regular intervals, on the outside. The insulation is then pumped into the cavity through these holes, and the holes are filled in so that they match the rest of the wall.

You could reduce your energy bills by up to 30%. In less than a day.

Cavity insulation is pumped into the cavity of your walls and acts as a barrier. Preventing heat from escaping. Which leads to a more comfortable home and lower heating bills.

All holes are patched by our staff after the pumping is complete
