Underfloor insulation for Maidstone properties
We cover Maidstone and the ME16 postcode district, including nearby Chatham, Rochester and Gillingham. Maidstone is one of the main towns we cover in Kent.
We check ventilation as carefully as insulation in Maidstone homes, because both matter for keeping a house dry. Where a Maidstone home also has empty cavity walls, we can survey those at the same time.
On compliance, if cavity wall insulation follows in Maidstone, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

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.
