Questions about room-in-roof insulation in Lewes

Is loft work in Lewes 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.

What do I need to do before you arrive in Lewes?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Do you charge extra to travel to Lewes?

Not normally. Our guide prices include normal travel to Lewes. 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.

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.
