Remove and refill across East Sussex

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

Local weather affects which walls can be filled. 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.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for East Sussex properties, so you can choose who fixes them. Where an East Sussex 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.

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.

Sources: Planning Portal: cavity wall insulation and building regulations; CIGA: CWISC competent person scheme.

Why refill at all?

Often the original problem was the wrong material for the exposure, poor installation or defects in the outer wall, not cavity insulation as such. Once the defects are fixed and the cavity is clean, a suitable certified system can usually go back in. Where the wall is too exposed for any fill, we say so and leave it empty.
