Where a Thornaby-on-Tees wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up. We never cold-call in Thornaby-on-Tees or anywhere else, and we do not work with doorstep claims companies.

Exposure matters for every cavity wall. 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.
