Cavity wall suitability survey for Bexley properties

Bexley sits in Greater London, roughly 12 miles east of London. We work across the DA5 district, including nearby Welling, Eltham and Thamesmead.

Where a Bexley wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Every inspection point in Bexley is photographed and logged, so you have a record to show a buyer, lender or contractor.

Local weather affects which walls can be filled. Much of Greater London sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

As for paperwork, in Bexley 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.
