Cavity wall insulation for Rottingdean properties
If your property is in Rottingdean or the BN2 district or nearby Brighton, Hove and Seaford, it is within our East Sussex coverage. It is around 4 miles east of Brighton.
Most Rottingdean 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. If a wall in Rottingdean 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.
Exposure matters for every cavity wall. East Sussex has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
On compliance, in Rottingdean filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

What happens on the day?
Holes of around 22mm are drilled in the mortar joints in a set pattern, roughly a metre apart. The insulation is blown in from the bottom up until each section is full, then every hole is filled with colour-matched mortar. Air bricks and flues are protected, and a cavity barrier is fitted where your wall joins a neighbour's.
