Blown mineral wool insulation for Brighton properties
Brighton sits in East Sussex. We work across the BN1 district, including nearby Hove, Rottingdean and Seaford.
A suitable wall in Brighton is usually filled in a single day from outside, with drill holes made good to match the pointing. For semi-detached and terraced homes in Brighton, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Before any material is chosen, exposure is checked. 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 Brighton filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England
In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

When is it not the right choice?
Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
