Questions about room-in-roof insulation in Harlow
Do you charge extra to travel to Harlow?
Not normally. Our guide prices include normal travel to Harlow. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Do you cover all of CM20?
Yes, we cover the CM20 postcode district and the districts around Harlow.
Is loft work in Harlow 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.
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.
