Thermal imaging survey for Farnham properties

Farnham is among the towns we cover in Surrey, alongside Godalming, Camberley and Guildford. It is roughly 10 miles west of Guildford.

Every inspection point in Farnham is photographed and logged, so you have a record to show a buyer, lender or contractor. A survey in Farnham 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 Surrey 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 compliance, if cavity wall insulation follows in Farnham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

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.
