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 Southampton
Do you cover all of SO14?
Yes, we cover the SO14 postcode district and the districts around Southampton.
Can a landlord in Southampton book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
How soon can you visit a home in Southampton?
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.
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.
