Questions about room-in-roof insulation in Beckenham
Do you cover all of BR3?
Yes, we cover the BR3 postcode district and the districts around Beckenham.
What do I need to do before you arrive in Beckenham?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
Do you take on jobs outside Beckenham?
Yes. We also work in Bromley and Catford and elsewhere in Greater London.
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.
