Thermal imaging survey for Chester-le-Street properties

Our County Durham coverage takes in Chester-le-Street (DH2) and nearby Stanley, Durham and Seaham. It is around 6 miles north of Durham.

A survey in Chester-le-Street gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Buyers and sellers in Chester-le-Street often book this check when a survey report or EPC raises questions about the walls.

Local weather affects which walls can be filled. 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.

On the rules side, if cavity wall insulation follows in Chester-le-Street, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England
