Damp investigation after cavity insulation across Clwyd
We cover 8 towns in Clwyd, including Wrexham, Buckley, Deeside, Colwyn Bay, Flint and more.
Every elevation is judged on its own exposure. Parts of Clwyd 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.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Clwyd properties, so you can choose who fixes them. We never cold-call in Clwyd or anywhere else, and we do not work with doorstep claims companies.
Building Regulations in Wales
In Wales, filling an existing cavity is also notifiable building work under the Building Regulations as they apply in Wales. A registered installer normally self-certifies it through a competent person scheme; otherwise a building notice goes to your council's building control before work starts. Welsh rules can differ from England's, so the notification route is confirmed in writing on your quote.
