Borescope cavity inspection for Welwyn Garden City properties
Welwyn Garden City sits in Hertfordshire, about 6 miles north-east of St Albans. We work across the AL8 district, including nearby Hatfield, Hertford and St Albans.
A survey in Welwyn Garden City gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Every inspection point in Welwyn Garden City is photographed and logged, so you have a record to show a buyer, lender or contractor.
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.
In terms of approvals, if cavity wall insulation follows in Welwyn Garden City, 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.
