Questions about room-in-roof insulation in Dolgellau
Do you take on jobs outside Dolgellau?
Yes. We also work in Porthmadog and Pwllheli and elsewhere in Gwynedd.
Can a landlord in Dolgellau book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Can you visit Dolgellau outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
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.
