Borescope cavity inspection across Dorset
We cover 4 towns in Dorset: Bournemouth, Poole, Weymouth and Christchurch.
Wind-driven rain is the first thing the surveyor weighs up. Dorset has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
A survey in Dorset gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Buyers and sellers in Dorset 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.
