Cavity insulation top-up for Bury St Edmunds properties
Our Suffolk coverage takes in Bury St Edmunds (IP33) and nearby Stowmarket, Sudbury and Haverhill. It is around 23 miles north-west of Ipswich.
Most Bury St Edmunds houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. Where a Bury St Edmunds property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Exposure matters for every cavity wall. 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.
As for paperwork, in Bury St Edmunds filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

When a top-up is not enough
If the existing fill is wet, contaminated with debris or breaking down, adding more on top can make things worse. In that case we tell you the honest option, which may be partial or full removal and refill.
