Thermal imaging survey for Barnet properties

We cover Barnet and the EN5 postcode district, including nearby Hadley Wood, Finchley and Muswell Hill. It is roughly 11 miles north of London.

Every inspection point in Barnet is photographed and logged, so you have a record to show a buyer, lender or contractor. A survey in Barnet gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Wind-driven rain is the first thing the surveyor weighs up. 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.

In terms of approvals, if cavity wall insulation follows in Barnet, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
