Wall tie replacement for Belfast properties

We cover Belfast and the BT1 postcode district, including nearby Newtownabbey, Lisburn and Carrickfergus. Belfast is one of the main towns we cover in County Antrim.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Belfast properties, so you can choose who fixes them. Damp in an insulated Belfast 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 County Antrim 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 Belfast, inserting cavity wall insulation needs a building control application to the council before work 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.
