Borescope cavity inspection for Thornaby-on-Tees properties
We cover Thornaby-on-Tees and the TS17 postcode district, including nearby Stockton-on-Tees, Billingham and Darlington. It is about 20 miles south-east of Durham.
A survey in Thornaby-on-Tees gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Where a Thornaby-on-Tees wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
Every elevation is judged on its own exposure. 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.
In terms of approvals, if cavity wall insulation follows in Thornaby-on-Tees, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
