Borescope cavity inspection in Durham

A borescope inspection pushes a small camera through a hole about the size of a pencil into the cavity to see whether it is empty, partly filled or filled, what the fill is and whether there is debris. We cover Durham and the wider DH1 postcode district, and the price is confirmed before anyone visits.

Borescope cavity inspection for Durham properties

Durham is among the towns we cover in County Durham, alongside Chester-le-Street, Stanley and Bishop Auckland. Durham is one of the main towns we cover in County Durham.

A survey in Durham gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Where a Durham 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.

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