Damp investigation after cavity insulation for Hertford properties
If your property is in Hertford or the SG13 district or nearby Hoddesdon, Welwyn Garden City and Hatfield, it is within our Hertfordshire coverage. It is around 11 miles east of St Albans.
Damp in an insulated Hertford home is not always the insulation's fault, so the diagnosis comes before any extraction. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Hertford properties, so you can choose who fixes them.
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.
As for paperwork, if cavity wall insulation follows in Hertford, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
