What is blown loft insulation?

The machine stays outside or on the landing and the hose runs up to the loft. Depth markers fixed to the joists or trusses show the installed depth, and the fibre settles into corners that rolls would bridge. More about blown loft insulation.

Questions about blown loft insulation in Guildford

What do I need to do before you arrive in Guildford?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Do you take on jobs outside Guildford?

Yes. We also work in Godalming and Woking and elsewhere in Surrey.

Will I get a written quote for work in Guildford?

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.

Is it messy?

The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
