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 Dorchester

Do you charge extra to travel to Dorchester?

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

Will I get a written quote for work in Dorchester?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

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

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.
