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 Nailsea

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

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.

How soon can you visit a home in Nailsea?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

Do you take on jobs outside Nailsea?

Yes. We also work in Portishead and Clevedon and elsewhere in Somerset.

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.

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.
