Questions about room-in-roof insulation in Falmouth
Is loft work in Falmouth 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 do I pay for work in Falmouth?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Can a landlord in Falmouth 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.
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.
