Wall tie replacement across County Down

We cover 5 towns in County Down: Bangor, Newtownards, Newry, Downpatrick and Banbridge.

Before any material is chosen, exposure is checked. Parts of County Down 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.

If your County Down installation has a guarantee, we check it first; the guarantee route may cover the work. Where a County Down 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 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.
