Questions about room-in-roof insulation in Orpington

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

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

Is loft work in Orpington 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 take on jobs outside Orpington?

Yes. We also work in Sidcup and Bromley and elsewhere in Greater London.

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.

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.
