Damp investigation after cavity insulation for Cheshunt properties
We cover Cheshunt and the EN8 postcode district, including nearby Hoddesdon, Potters Bar and Hertford. It is about 14 miles east of St Albans.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Cheshunt properties, so you can choose who fixes them. If your Cheshunt installation has a guarantee, we check it first; the guarantee route may cover the work.
Local weather affects which walls can be filled. 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 Cheshunt, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
