Cavity cleaning and debris removal for Seaford properties

Seaford is among the towns we cover in East Sussex, alongside Rottingdean, Eastbourne and Hailsham. It is roughly 11 miles east of Brighton.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Seaford properties, so you can choose who fixes them. Where a Seaford wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.

Before any material is chosen, exposure is checked. 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, if cavity wall insulation follows in Seaford, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

Why debris matters

A clean cavity lets water that gets through the outer leaf drain away. Debris piled at the base or caught on ties makes a bridge for that water. It is a common cause of damp low on walls and around ties, with or without insulation.
