Thermal imaging survey for Portsmouth properties

If your property is in Portsmouth or the PO1 district or nearby Gosport, Fareham and Havant, it is within our Hampshire coverage. It is roughly 16 miles south-east of Southampton.

Every inspection point in Portsmouth is photographed and logged, so you have a record to show a buyer, lender or contractor. The written result for your Portsmouth 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. 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.
