Bonded polystyrene bead insulation for Deal properties
We cover Deal and the CT14 postcode district, including nearby Dover, Ramsgate and Broadstairs. It is around 39 miles east of Maidstone.
If a wall in Deal is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. Most Deal houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.
Before any material is chosen, exposure is checked. Much of Kent sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
On the rules side, in Deal filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England
In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

What to know before you choose beads
Polystyrene is combustible, so beads are not the right choice for every building; height, use and nearby openings matter, and the system certificate sets the limits. PVC-sheathed cables in the cavity should be sleeved or kept out of contact with the beads where the certificate requires it. We check both at survey.
