Questions about room-in-roof insulation in Hertford

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

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

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

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.

Is loft work in Hertford 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.

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.
