Questions about room-in-roof insulation in Brentwood

Can you visit Brentwood outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

Can a landlord in Brentwood book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Do you take on jobs outside Brentwood?

Yes. We also work in Billericay and Basildon and elsewhere in Essex.

Will the room get smaller?

Slightly. Insulated plasterboard over the rafters takes a few centimetres off each slope.

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.
