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.

Questions about room-in-roof insulation in Sinfin
Will I get a written quote for work in Sinfin?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Is loft work in Sinfin different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
How soon can you visit a home in Sinfin?
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.
How long does room-in-roof insulation take?
Usually three to six working days for one room, depending on how much is stripped and how it is finished.
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.
