Cavity wall suitability survey for Yeovil properties

Yeovil sits in Somerset, roughly 21 miles east of Taunton. We work across the BA20 district, including nearby Bridgwater, Taunton and Frome.

A survey in Yeovil gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Every inspection point in Yeovil is photographed and logged, so you have a record to show a buyer, lender or contractor.

Local weather affects which walls can be filled. Somerset 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 Yeovil 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.
