Party wall cavity insulation for Bury St Edmunds properties
Our Suffolk coverage takes in Bury St Edmunds (IP33) and nearby Stowmarket, Sudbury and Haverhill. It is roughly 23 miles north-west of Ipswich.
If a wall in Bury St Edmunds is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. 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.
Before any material is chosen, exposure is checked. 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.

What we need from you and your neighbour
The cavity is shared, so we talk you through notifying your neighbour before work. Filling is done from your side, usually through the loft. The survey confirms the wall is a cavity wall and not solid masonry, and checks for cables, flues and any gaps that would let fill escape.
