Questions about room-in-roof insulation in Guildford

Do you cover all of GU1?

Yes, we cover the GU1 postcode district and the districts around Guildford.

Is loft work in Guildford different from anywhere else?

The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.

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

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.

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.

Will the room get smaller?

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