Underfloor insulation for Clevedon properties
We cover Clevedon and the BS21 postcode district, including nearby Nailsea, Portishead and Weston-super-Mare. It is roughly 31 miles north of Taunton.
Where a Clevedon home also has empty cavity walls, we can survey those at the same time. We check ventilation as carefully as insulation in Clevedon homes, because both matter for keeping a house dry.
For regulations, if cavity wall insulation follows in Clevedon, 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.
