Cavity insulation for new builds and extensions for Hartlepool properties
If your property is in Hartlepool or the TS26 district or nearby Peterlee, Billingham and Stockton-on-Tees, it is within our County Durham coverage. It is around 16 miles south-east of Durham.
If a wall in Hartlepool 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. For semi-detached and terraced homes in Hartlepool, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Exposure matters for every cavity wall. County Durham 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 Hartlepool filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
