Borescope cavity inspection for Potters Bar properties

Our Hertfordshire coverage takes in Potters Bar (EN6) and nearby Borehamwood, Hatfield and Cheshunt. It is roughly 7 miles south-east of St Albans.

Every inspection point in Potters Bar is photographed and logged, so you have a record to show a buyer, lender or contractor. Where a Potters Bar wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.

Wind-driven rain is the first thing the surveyor weighs up. 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.
