Wall tie replacement sydney is the specialist masonry repair that restores the hidden metal ties holding a cavity brick wall together, and Premier Pointing brings 30 years of accumulated experience to this work across Sydney and NSW. When the original ties inside an older brick wall corrode and fail, the two skins of brickwork stop acting as one, which puts the wall at structural risk. Our fully licensed team locates the failed ties, installs new corrosion resistant replacements and stabilises the wall, all without the disruption and cost of rebuilding it.
What are wall ties and why do they matter?
Most Sydney homes built with cavity walls have two separate leaves of brickwork, an inner leaf and an outer leaf, with a gap between them. On their own, these two thin skins are not strong enough to stand as one wall. Wall ties are the small metal connectors, usually embedded in the mortar joints, that bridge the cavity and tie the inner and outer leaves together so they behave as a single structural unit. They also let each leaf share wind and structural loads. When the ties are sound, the wall is stable and the cavity still does its job of keeping moisture out of the inner leaf. When the ties fail, that structural partnership breaks down, and that is exactly the problem that wall tie replacement sydney is designed to solve.
How do wall ties fail over time?
The ties used in older Sydney and NSW buildings were commonly made from steel or iron. Over the decades, moisture in the cavity causes these older metal ties to corrode. As the metal rusts, it expands, and rust can occupy several times the volume of the original steel. That expansion is powerful enough to force the surrounding brickwork apart from the inside. The result is that the mortar bed sitting on the tie is slowly jacked open, the joint cracks, and over many years the outer leaf can begin to move, bow or separate from the wall behind it. Because the ties are buried inside the wall, this corrosion is invisible from the outside until the movement it causes starts to show on the surface. Heritage and period masonry is particularly prone to this, which is why our restoration experience, extending to work on the London Underground railway network, is so relevant to older Sydney properties.
What are the signs of wall tie failure?
There are several tell tale signs that a wall may need wall tie replacement sydney. Because failed ties expand at regular intervals up the wall, the damage often appears in a repeating pattern rather than at random. Look out for the following:
- Regular horizontal cracks that repeat at the same coursing where the ties sit, often spaced evenly up the wall.
- Bulging or bowing walls, where the outer leaf of brickwork begins to lean out or belly away from the structure behind it.
- Cracked mortar joints forming a stepped or horizontal pattern through the brickwork.
- Gaps opening up around window and door frames as the outer leaf shifts.
- Bricks that sound hollow or loose when tapped, a hint that the leaf is no longer firmly tied back.
If you notice any of these on your property, it is worth having the wall inspected before the movement worsens. Some of these symptoms overlap with other masonry issues, so a proper assessment matters. Our team can advise whether the cause is tie corrosion or something that our repointing or wider brick restoration services are better suited to address.
How does remedial wall tie replacement sydney work?
The great advantage of modern remedial wall tie replacement sydney is that it stabilises the wall without rebuilding it. Our process follows clear, considered steps:
- Assessment. We inspect the wall, read the crack pattern and confirm that corroded ties are the underlying cause of the movement.
- Locating the ties. We identify where the existing ties sit within the wall so new ties can be placed to a correct and effective pattern.
- Installing new ties. We install new corrosion resistant stainless steel remedial ties that reconnect the inner and outer leaves. Depending on the wall, these are either mechanically fixed, which grip the brickwork by expansion, or resin fixed, which are bonded into place with a structural resin.
- Neutralising the old ties. Where needed, the failed original ties are isolated so they can no longer force the brickwork apart as they continue to corrode.
- Making good. We repair and repoint the affected joints so the finished wall is both sound and tidy, blending with the surrounding heritage or period brickwork.
Because the new ties are installed through small, carefully placed drill points in the mortar or brick face, there is no need to demolish and rebuild the wall. That keeps disruption, cost and mess to a minimum while delivering a genuine structural repair.
Why you should not ignore failing wall ties
Failing wall ties are not a cosmetic problem. Once the ties can no longer hold the two leaves together, the outer leaf is effectively a thin, tall skin of brickwork carrying loads it was never designed to carry alone. Left unaddressed, the bowing gets worse, cracks widen, and in severe cases sections of the outer leaf can become unstable. Acting early, while the movement is still modest, almost always means a simpler and less costly repair. This is why prompt wall tie replacement sydney is one of the most valuable pieces of preventative masonry work an older building can have. It protects the structure, preserves the original brickwork and avoids the far larger job of rebuilding a wall that has been allowed to move too far.

Frequently asked questions
How do I know if my wall actually needs wall ties replaced?
The clearest indicators are regular horizontal cracking at the tie coursing, bowing or bulging of the outer brickwork and stepped or horizontal cracking through the mortar joints. Because these signs can be caused by more than one issue, the reliable way to know is to have the wall inspected by an experienced masonry team who can read the crack pattern and confirm whether corroded ties are the cause.
Do you have to knock down the wall to replace the ties?
No. Modern remedial wall tie replacement is designed to avoid rebuilding. New stainless steel remedial ties are installed through small drill points and either mechanically fixed or resin fixed into the brickwork, reconnecting the two leaves without demolishing the wall. This makes the repair far less disruptive and less costly than a rebuild.
What are the new ties made from?
We use corrosion resistant stainless steel remedial ties. Unlike the older steel or iron ties that rust and expand over time, stainless steel is designed to resist corrosion, so the repair is built to give the wall a long, stable future rather than repeating the original problem.
Do you work on heritage and period buildings?
Yes. Heritage and period masonry is our speciality, and it is also the kind of building most likely to have corroded original ties. Our experience, which extends to restoration work on the London Underground railway network, means we approach older brickwork carefully and sympathetically so the finished repair respects the original wall.
