What our customers say
A prompt response to the initial enquiry and a quick, tidy installation of Knauf product. I cannot believe how much quieter, warmer and snug the house felt immediately, and reasonably priced.

We recently had our roof insulation installed and could not be happier with the service. Communication was clear throughout and he arrived on time as promised. The work was carried out to a high standard, and everything was left clean and tidy.
JamieApril 2026
A great job installing insulation in my entire ceiling cavity, including the garage ceiling. Sonny quoted promptly and held the quote until I needed the work done. The team were punctual, friendly, efficient, and cleaned up afterwards.

Where we install Knauf Earthwool
Earthwool is used in ceilings and walls, in new builds and retrofits. It is a good option where a high R value is specified and thickness matters.
At the quote we confirm the R value your ceiling, walls or floor need, how many bales the job takes, and whether Earthwool or one of the polyester products is the better fit. Insulation only performs to its rated R value when it is cut to fit and installed with no gaps or compression, which is the part we take care over.
