Cavity wall suitability survey for Northwich properties
Northwich sits in Cheshire, around 16 miles east of Chester. We work across the CW9 district, including nearby Winsford, Warrington and Runcorn.
A survey in Northwich gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Every inspection point in Northwich is photographed and logged, so you have a record to show a buyer, lender or contractor.
Exposure matters for every cavity wall. Cheshire 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 Northwich filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.
