Do you charge extra to travel to Chelmsford?
Not normally. Our guide prices include normal travel to Chelmsford. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
