Cavity wall suitability survey for Thornaby-on-Tees properties
Our County Durham coverage takes in Thornaby-on-Tees (TS17) and nearby Stockton-on-Tees, Billingham and Darlington. It is about 20 miles south-east of Durham.
Every inspection point in Thornaby-on-Tees is photographed and logged, so you have a record to show a buyer, lender or contractor. The written result for your Thornaby-on-Tees property is plain English: what we found, what it means and what, if anything, to do next.
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.
For regulations, in Thornaby-on-Tees filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
