Underfloor insulation in Great Yarmouth

Underfloor insulation in Great Yarmouth starts with a free survey of the property, then a written result and a fixed price before any work is booked. Underfloor insulation fits mineral wool or rigid boards between the joists of a suspended timber floor, supported on netting or battens, so cold air from the ventilated void below stops chilling the room.

Where a Great Yarmouth home also has empty cavity walls, we can survey those at the same time. In Great Yarmouth homes this is often done on the same visit as a cavity fill, which saves a second trip.

On the rules side, if cavity wall insulation follows in Great Yarmouth, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Keeping the void ventilated

Air bricks under a suspended floor must stay clear so the timbers stay dry. Insulation goes between the joists, not across the void, and gaps at skirtings are sealed to stop draughts.
