What is room-in-roof insulation?
Most rooms-in-roof are reached by stripping the existing plasterboard on the slopes, fitting insulation between and over the rafters, and re-boarding. Where there is access behind the knee walls, we insulate the eaves voids and the floor behind them too. More about room-in-roof insulation.
- Insulation to slopes, knee walls and flat ceiling
- Eaves voids insulated where accessible

Questions about room-in-roof insulation in Chertsey
Can a landlord in Chertsey 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 take on jobs outside Chertsey?
Yes. We also work in Weybridge and Staines-upon-Thames and elsewhere in Surrey.
Will I get a written quote for work in Chertsey?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
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.
