Cavity wall suitability survey for Corby properties
Our Northamptonshire coverage takes in Corby (NN17) and nearby Kettering, Market Harborough and Wellingborough. It is roughly 19 miles north-east of Northampton.
A survey in Corby gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Buyers and sellers in Corby often book this check when a survey report or EPC raises questions about the walls.
Local weather affects which walls can be filled. Much of Northamptonshire 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 Corby 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.
