Damp investigation after cavity insulation for Hitchin properties
Hitchin sits in Hertfordshire, around 14 miles north of St Albans. We work across the SG6 district, including nearby Letchworth Garden City, Stevenage and Harpenden.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Hitchin properties, so you can choose who fixes them. Damp in an insulated Hitchin home is not always the insulation's fault, so the diagnosis comes before any extraction.
Every elevation is judged on its own exposure. 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 compliance, if cavity wall insulation follows in Hitchin, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
