Borescope cavity inspection for Harpenden properties
Harpenden sits in Hertfordshire, about 5 miles north of St Albans. We work across the AL5 district, including nearby St Albans, Hemel Hempstead and Welwyn Garden City.
The written result for your Harpenden property is plain English: what we found, what it means and what, if anything, to do next. A survey in Harpenden gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Exposure matters for every cavity wall. 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.
As for paperwork, if cavity wall insulation follows in Harpenden, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

How many holes?
Enough to be representative: typically several per elevation, plus targeted checks below windows, at corners and near any damp patches. Each one is photographed and logged.
