Cavity wall suitability survey across East Sussex

We cover 9 towns in East Sussex, including Brighton, Eastbourne, Hastings, Hove, Bexhill-on-Sea and more.

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.

The written result for your East Sussex property is plain English: what we found, what it means and what, if anything, to do next. A survey in East Sussex gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Building Regulations in England

Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

What the surveyor checks

Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.

What is included

  • Photo-backed written result
  • Cavity width and debris check
  • Exposure assessment by elevation
  • Repairs list where needed
