Every elevation is judged on its own exposure. Parts of Mid Glamorgan 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.

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

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.

Tracing a guarantee

Many cavity fills carry a 25-year guarantee from the Cavity Insulation Guarantee Agency (CIGA). CIGA can confirm whether a property is covered and can issue a duplicate guarantee for a fee; at the time of writing that fee is £60 including VAT, and proof of ownership is required.
