What is rafter insulation?
Because the whole roof slope, the gables and the party walls now have to be insulated, this costs much more than insulating the floor and saves less heat for the money. It earns its place when you need a warm loft. More about rafter insulation.

We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.

Questions about rafter insulation in Wimbledon
How soon can you visit a home in Wimbledon?
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 do I pay for work in Wimbledon?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you take on jobs outside Wimbledon?
Yes. We also work in Morden and Mitcham and elsewhere in Greater London.
Is insulating between the rafters better than the loft floor?
Not for saving energy alone. Insulating the floor heats less space and costs far less. Rafter insulation is the right answer when the loft itself needs to be warm.
Will it cause condensation?
It can if the build-up is wrong for the roof. Old bitumen felt needs a ventilation gap behind the insulation; a modern breathable membrane may not. We check before we design it.
