Questions about room-in-roof insulation in Launceston

Can you visit Launceston outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

Is loft work in Launceston 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.

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

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

Will the room get smaller?

Slightly. Insulated plasterboard over the rafters takes a few centimetres off each slope.
