At Gary McKibbin Preservation, we specialise in wall tie inspection and replacement throughout Belfast and across Northern Ireland.
Wall ties are crucial components in cavity wall construction, providing structural stability by connecting the inner and outer leaves of brickwork. Over time, these metal ties can corrode, weaken, or fail — leading to cracks, bulging walls, and even structural movement.
With over 40 years of experience, our trained surveyors use advanced inspection tools to detect wall tie failure early and replace them using industry-approved techniques, restoring your property’s safety and stability.

We’ve earned a strong reputation across Northern Ireland for precision, reliability, and professional workmanship in structural repair and restoration.
