Questions about room-in-roof insulation in Hayes
How soon can you visit a home in Hayes?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Can a landlord in Hayes 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 cover all of UB3?
Yes, we cover the UB3 postcode district and the districts around Hayes.
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.
