Borescope cavity inspection across Surrey
We cover 18 towns in Surrey, including Woking, Guildford, Esher, Redhill, Staines and more.
Local weather affects which walls can be filled. 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.
Every inspection point in Surrey is photographed and logged, so you have a record to show a buyer, lender or contractor. Where a Surrey wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
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.
