Borescope cavity inspection across Cornwall
We cover 8 towns in Cornwall, including Redruth, Falmouth, St Austell, Truro, Camborne and more.
Before any material is chosen, exposure is checked. Parts of Cornwall face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
The written result for your Cornwall property is plain English: what we found, what it means and what, if anything, to do next. Buyers and sellers in Cornwall often book this check when a survey report or EPC raises questions about the walls.
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.
