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 Eltham

Can you visit Eltham 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.

What do I need to do before you arrive in Eltham?

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.

Do you charge extra to travel to Eltham?

Not normally. Our guide prices include normal travel to Eltham. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

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.
