Questions about room-in-roof insulation in Wiltshire

How do I book a survey in Wiltshire?

Send the form or call us. We call back to agree a time and confirm it in writing.

Are your prices the same across Wiltshire?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

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.

How long does room-in-roof insulation take?

Usually three to six working days for one room, depending on how much is stripped and how it is finished.
