Cavity wall suitability survey for Sudbury properties
If your property is in Sudbury or the CO10 district or nearby Haverhill, Bury St Edmunds and Stowmarket, it is within our Suffolk coverage. It is around 18 miles west of Ipswich.
A survey in Sudbury gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Every inspection point in Sudbury is photographed and logged, so you have a record to show a buyer, lender or contractor.
Every elevation is judged on its own exposure. Much of Suffolk 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.
For regulations, in Sudbury 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.

What the surveyor checks
Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.
