What is blown loft insulation?
The machine stays outside or on the landing and the hose runs up to the loft. We hold a board or tray at the eaves so the loose fill cannot block the ventilation path. More about blown loft insulation.

Questions about blown loft insulation in Chertsey
Can you visit Chertsey outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
Do you take on jobs outside Chertsey?
Yes. We also work in Weybridge and Staines-upon-Thames and elsewhere in Surrey.
Will I get a written quote for work in Chertsey?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Is blown insulation better than rolls?
It performs about the same for the same depth. It is the faster and neater option in lofts that are awkward to work in, and rolls are better where you want boarding later.
Does blown insulation settle?
Mineral wool loose fill settles a little, which is allowed for in the depth we install. The depth markers let you check it later.
