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.

Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.
How long does room-in-roof insulation take?
