Questions about room-in-roof insulation in Carlisle

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

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.

Can a landlord in Carlisle book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Do you take on jobs outside Carlisle?

Yes. We also work in Penrith and Cockermouth and elsewhere in Cumbria.

Will the room get smaller?

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

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.
