Questions about room-in-roof insulation in Woolwich
What do I need to do before you arrive in Woolwich?
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.
Can you visit Woolwich 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.
Do you take on jobs outside Woolwich?
Yes. We also work in Welling and Eltham 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.
