Thermal imaging survey for Finchley properties

Finchley sits in Greater London, roughly 7 miles north-west of London. We work across the N3 district, including nearby Muswell Hill, Cricklewood and Kilburn.

A survey in Finchley gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Every inspection point in Finchley 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 Greater London 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.

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

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.
