Borescope cavity inspection in Portsmouth

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.

Borescope cavity inspection for Portsmouth properties

Portsmouth sits in Hampshire, roughly 16 miles south-east of Southampton. We work across the PO1 district, including nearby Gosport, Fareham and Havant.

Every inspection point in Portsmouth is photographed and logged, so you have a record to show a buyer, lender or contractor. Buyers and sellers in Portsmouth often book this check when a survey report or EPC raises questions about the walls.

Local weather affects which walls can be filled. Hampshire 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 Portsmouth, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
