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.

Why book with us in Clapham
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Questions about blown loft insulation in Clapham
Can a landlord in Clapham book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
How do I pay for work in Clapham?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Can you visit Clapham 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.
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.
