Questions about room-in-roof insulation in Pwllheli
Do you take on jobs outside Pwllheli?
Yes. We also work in Porthmadog and Caernarfon and elsewhere in Gwynedd.
Is loft work in Pwllheli 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.
Will I get a written quote for work in Pwllheli?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
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.
