Questions about room-in-roof insulation in Lancing

Is loft work in Lancing 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 charge extra to travel to Lancing?

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

How do I pay for work in Lancing?

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

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.
