Questions about room-in-roof insulation in Salisbury
How do I pay for work in Salisbury?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Will I get a written quote for work in Salisbury?
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 Salisbury?
Yes. We also work in Warminster and Devizes and elsewhere in Wiltshire.
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.
