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 Walthamstow
How do I pay for work in Walthamstow?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you take on jobs outside Walthamstow?
Yes. We also work in Leytonstone and Tottenham and elsewhere in Greater London.
What do I need to do before you arrive in Walthamstow?
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.
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 it messy?
The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
