Party wall cavity insulation for Hailsham properties
If your property is in Hailsham or the BN27 district or nearby Eastbourne, Seaford and Bexhill-on-Sea, it is within our East Sussex coverage. It is roughly 17 miles east of Brighton.
Hailsham properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. For semi-detached and terraced homes in Hailsham, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Every elevation is judged on its own exposure. East Sussex has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
In terms of approvals, in Hailsham 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.
What is included in Hailsham
- Sealing at the top of the cavity
- Loft inspection and borescope check
- Written result and photos
- Certified fill to the separating wall
