Borescope cavity inspection for Watford properties
If your property is in Watford or the WD17 district or nearby Rickmansworth, Borehamwood and St Albans, it is within our Hertfordshire coverage. It is roughly 7 miles south of St Albans.
A survey in Watford gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Where a Watford wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
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.
On the rules side, if cavity wall insulation follows in Watford, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

When a borescope check helps
Before filling, to confirm the cavity is empty and clean. Before buying a house, to see if the EPC's claim of 'filled cavity' is true. When damp has appeared and you need to know whether the fill is wet or bridged. Before a top-up, to map which panels are empty.
