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 Gainsborough
Will I get a written quote for work in Gainsborough?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
How do I pay for work in Gainsborough?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you cover all of DN21?

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