Thermal imaging survey for Rickmansworth properties
If your property is in Rickmansworth or the WD3 district or nearby Watford, Hemel Hempstead and Borehamwood, it is within our Hertfordshire coverage. It is roughly 10 miles south-west of St Albans.
Buyers and sellers in Rickmansworth often book this check when a survey report or EPC raises questions about the walls. A survey in Rickmansworth gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Local weather affects which walls can be filled. 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 Rickmansworth, 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.
