Questions about room-in-roof insulation in Doncaster

How do I pay for work in Doncaster?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

Do you charge extra to travel to Doncaster?

Not normally. Our guide prices include normal travel to Doncaster. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Is loft work in Doncaster 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 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.
