Cavity wall suitability survey for Walton-on-Thames properties

Walton-on-Thames is among the towns we cover in Surrey, alongside Sunbury-on-Thames, Esher and Staines. It is roughly 12 miles north-east of Guildford.

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

Every elevation is judged on its own exposure. Much of Surrey 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.

For regulations, in Walton-on-Thames filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
