Thermal imaging survey across County Durham

We cover 13 towns in County Durham, including Darlington, Hartlepool, Stockton-on-Tees, Durham, Chester-le-Street and more.

Wind-driven rain is the first thing the surveyor weighs up. County Durham 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.

Where a County Durham wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. The written result for your County Durham property is plain English: what we found, what it means and what, if anything, to do next.

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.

Useful for

Checking an old installation, planning a top-up, finding where an extension's insulation stops, and giving landlords evidence before and after works.
