Cavity wall insulation removal for Seaford properties

Our East Sussex coverage takes in Seaford (BN25) and nearby Rottingdean, Eastbourne and Hailsham. It is about 11 miles east of Brighton.

If your Seaford installation has a guarantee, we check it first; the guarantee route may cover the work. 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

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

Should I remove my cavity wall insulation?

Not always. Welsh Government guidance makes the point that extraction is not always the right remedy. Damp can come from blocked gutters, failed pointing, bridged damp-proof courses or condensation, none of which removal fixes. We start with a damp investigation and borescope checks, then recommend removal only where the fill itself is the problem.

What is included in Seaford

  • Camera check before rebuild
  • Waste disposal
  • Full extraction and cavity clean
  • Damp investigation and borescope diagnosis first
