Cavity wall suitability survey for Egham properties
If your property is in Egham or the TW20 district or nearby Staines, Sunbury-on-Thames and Walton-on-Thames, it is within our Surrey coverage. It is around 14 miles north of Guildford.
Buyers and sellers in Egham often book this check when a survey report or EPC raises questions about the walls. Every inspection point in Egham is photographed and logged, so you have a record to show a buyer, lender or contractor.
Local weather affects which walls can be filled. Much of Surrey 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 the rules side, in Egham 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.
