Wall tie replacement for Penarth properties
Our South Glamorgan coverage takes in Penarth (CF64) and nearby Cardiff and Barry. It is around 3 miles south of Cardiff.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Penarth properties, so you can choose who fixes them. Damp in an insulated Penarth home is not always the insulation's fault, so the diagnosis comes before any extraction.
Every elevation is judged on its own exposure. Parts of South 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.
On compliance, if cavity wall insulation follows in Penarth, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

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.
