We cover Welwyn Garden City and the AL8 postcode district, including nearby Hatfield, Hertford and St Albans. It is about 6 miles north-east of 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. The written result for your Welwyn Garden City property is plain English: what we found, what it means and what, if anything, to do next.
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.
As for paperwork, 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
