Cavity wall suitability survey for King's Lynn properties
We cover King's Lynn and the PE30 postcode district, including nearby Thetford and Norwich. It is about 39 miles west of Norwich.
Every inspection point in King's Lynn is photographed and logged, so you have a record to show a buyer, lender or contractor. Where a King's Lynn wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
Local weather affects which walls can be filled. Much of Norfolk 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, in King's Lynn 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.
