Thermal imaging survey for Sevenoaks properties
Sevenoaks sits in Kent, about 14 miles west of Maidstone. We work across the TN13 district, including nearby Tonbridge, Swanley and Tunbridge Wells.
A survey in Sevenoaks gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Every inspection point in Sevenoaks is photographed and logged, so you have a record to show a buyer, lender or contractor.
Every elevation is judged on its own exposure. Much of Kent sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
In terms of approvals, if cavity wall insulation follows in Sevenoaks, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

What thermal images can and cannot show
They show patterns, not proof. A cooler stripe inside might be missing fill, a cold bridge at a lintel or simply a radiator switched off. That is why we pair the images with borescope checks before recommending any work.
