Cavity insulation for new builds and extensions for Kingswood properties
Kingswood is among the towns we cover in Gloucestershire, alongside Mangotsfield, Yate and Stroud. It is roughly 30 miles south of Gloucester.
For semi-detached and terraced homes in Kingswood, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. If a wall in Kingswood 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.
Exposure matters for every cavity wall. Gloucestershire 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.
As for paperwork, in Kingswood filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
