Cavity wall suitability survey across Surrey
We cover 18 towns in Surrey, including Woking, Guildford, Esher, Redhill, Staines and more.
Before any material is chosen, exposure is checked. 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.
The written result for your Surrey property is plain English: what we found, what it means and what, if anything, to do next. Every inspection point in Surrey is photographed and logged, so you have a record to show a buyer, lender or contractor.
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
