Wall tie replacement across County Londonderry
We cover 4 towns in County Londonderry: Derry, Coleraine, Limavady and Magherafelt.
Wind-driven rain is the first thing the surveyor weighs up. Parts of County Londonderry 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.
We never cold-call in County Londonderry or anywhere else, and we do not work with doorstep claims companies. Damp in an insulated County Londonderry home is not always the insulation's fault, so the diagnosis comes before any extraction.
Building control in Northern Ireland
In Northern Ireland, inserting insulation into an existing cavity wall needs a building control application to your council before the work. We make sure the application route is agreed and confirmed in writing before any drilling starts.

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.
