Questions about room-in-roof insulation in Pontypridd
Do you take on jobs outside Pontypridd?
Yes. We also work in Tonypandy and Rhondda and elsewhere in Mid Glamorgan.
Can a landlord in Pontypridd 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 charge extra to travel to Pontypridd?
Not normally. Our guide prices include normal travel to Pontypridd. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
