Questions about room-in-roof insulation in Caernarfon
Is loft work in Caernarfon 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 you visit Caernarfon 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.
Do you charge extra to travel to Caernarfon?
Not normally. Our guide prices include normal travel to Caernarfon. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Will the room get smaller?
Slightly. Insulated plasterboard over the rafters takes a few centimetres off each slope.
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.
