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.

Boarding done properly

Storage boards go on loft legs, never straight onto the insulation.

Questions about blown loft insulation in Putney

How soon can you visit a home in Putney?

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.

Will I get a written quote for work in Putney?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Do you take on jobs outside Putney?

Yes. We also work in Fulham and Hammersmith and elsewhere in Greater London.

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.
