Cavity wall suitability survey for Sevenoaks properties
Sevenoaks is among the towns we cover in Kent, alongside Tonbridge, Swanley and Tunbridge Wells. It is around 14 miles west of Maidstone.
Every inspection point in Sevenoaks is photographed and logged, so you have a record to show a buyer, lender or contractor. A survey in Sevenoaks gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Wind-driven rain is the first thing the surveyor weighs up. Much of Kent 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.
In terms of approvals, in Sevenoaks 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.
