Questions about room-in-roof insulation in Alton

How soon can you visit a home in Alton?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

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

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 cover all of GU34?

Yes, we cover the GU34 postcode district and the districts around Alton.

Can it be done without removing the plasterboard?

Sometimes the flat ceiling and eaves voids can be reached from behind. The slopes almost always need the boards off to insulate them properly.

Will the room get smaller?

Slightly. Insulated plasterboard over the rafters takes a few centimetres off each slope.
