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
- Boarding and finishing as agreed on the quote

The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.

We explain what we find in plain English, and say so when nothing needs doing.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Questions about room-in-roof insulation in Essex
Which council covers my address in Essex?
Councils in Essex include Essex, Southend-on-Sea and Thurrock. Your council matters for building control questions and some funding schemes.
Are your prices the same across Essex?
Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.
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.
