What is different about insulating a flat's loft?

In most leasehold flats the loft belongs to the freeholder, so the managing agent or freeholder must agree to the work. We can quote for a single flat or the whole block, and work to the managing agent's access and insurance requirements. More about loft insulation for a flat.

Why book with us in Dorset

We measure before we quote

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

Photos of the finished loft

You see the work done without climbing the ladder.

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.
