Questions about room-in-roof insulation in Dorking
Will I get a written quote for work in Dorking?
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 Dorking 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.
Do you cover all of RH4?
Yes, we cover the RH4 postcode district and the districts around Dorking.
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.
Will the room get smaller?
Slightly. Insulated plasterboard over the rafters takes a few centimetres off each slope.
