Do you take on jobs outside Risca?
Yes. We also work in Newport (Gwent) and Cwmbran and elsewhere in Gwent.
Is loft work in Risca 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.
Can you visit Risca 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.
How long does room-in-roof insulation take?
Usually three to six working days for one room, depending on how much is stripped and how it is finished.
Will the room get smaller?
Slightly. Insulated plasterboard over the rafters takes a few centimetres off each slope.
