Cavity wall suitability survey for Brecon properties

Brecon sits in Powys, around 39 miles south of Newtown. We work across the LD3 district, including nearby Llandrindod Wells and Newtown.

The written result for your Brecon property is plain English: what we found, what it means and what, if anything, to do next. Every inspection point in Brecon is photographed and logged, so you have a record to show a buyer, lender or contractor.

Local weather affects which walls can be filled. Parts of Powys face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

In terms of approvals, in Brecon filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.
