Questions about room-in-roof insulation in St Austell
Can a landlord in St Austell book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Will I get a written quote for work in St Austell?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Do you take on jobs outside St Austell?
Yes. We also work in Bodmin and Truro and elsewhere in Cornwall.
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.
