Wall tie replacement across Gwent

We cover 6 towns in Gwent, including Newport, Cwmbran, Pontypool, Ebbw Vale, Caerphilly and more.

Local weather affects which walls can be filled. Parts of Gwent 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.

Damp in an insulated Gwent home is not always the insulation's fault, so the diagnosis comes before any extraction. Where a Gwent wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.

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.

Signs of wall tie failure

Horizontal cracks in mortar joints at regular vertical intervals, bulging brickwork, or lifting of the roof verge. Older galvanised ties, especially in walls built before the 1980s, are the usual suspects.
