Wall tie replacement for Caerphilly properties

Our Gwent coverage takes in Caerphilly (CF83) and nearby Risca, Newport and Cwmbran. It is about 9 miles west of Newport.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Caerphilly properties, so you can choose who fixes them. If your Caerphilly installation has a guarantee, we check it first; the guarantee route may cover the work.

Wind-driven rain is the first thing the surveyor weighs up. 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.

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

Ties and cavity insulation

Ties should be checked before a cavity is filled. Fitting remedial ties does not normally stop a cavity being insulated later, and we can do both in one visit. Where cracking suggests movement, we recommend a structural engineer's view first.
