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.

Why book with us in Shaftesbury

Fixed written price

The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.

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.

We measure before we quote

Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Questions about blown loft insulation in Shaftesbury

Can you visit Shaftesbury 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.

Do you take on jobs outside Shaftesbury?

Yes. We also work in Wimborne Minster and Ferndown and elsewhere in Dorset.

Will I get a written quote for work in Shaftesbury?

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

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.
