Wall-tie replacement
Wall-tie inspection and replacement only where defect evidence, design and access support the work.
Why diagnosis matters
Treat the cause, then repair the damage
Wall ties connect masonry leaves. Corrosion or failure can be associated with cracking and instability, but wall-tie failure should not be used as a generic explanation for damp.

Common questions
About wall-tie replacement
Do failed wall ties cause damp?+
They are primarily a structural defect. Cracks or pathways may contribute to water entry in some cases, but ties are not a catch-all damp diagnosis.
How are ties checked?+
Specialist detection, endoscopy or testing may be required beyond visual clues.
Can you match the brick finish?+
We aim for neat making good, but exact weathered colour matching cannot always be guaranteed.
