Thermal imaging survey for Letchworth Garden City properties
Letchworth Garden City is among the towns we cover in Hertfordshire, alongside Hitchin, Stevenage and Welwyn Garden City. It is around 17 miles north of St Albans.
Every inspection point in Letchworth Garden City is photographed and logged, so you have a record to show a buyer, lender or contractor. Buyers and sellers in Letchworth Garden City often book this check when a survey report or EPC raises questions about the walls.
Before any material is chosen, exposure is checked. Much of Hertfordshire 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 Letchworth Garden City, 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.
