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 Greater London

Are your prices the same across Greater London?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

Can you quote for several properties in Greater London?

Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.

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.

Is it messy?

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