How to Spot and Repair Cracked Brick Walls in Your Perth Home

Cracked brick walls are a common issue in Perth homes, often caused by weather, ground movement, or ageing mortar. Knowing the signs early and getting the right repair can save thousands in long-term damage.

Why Cracks Appear in Brick Walls

There are several reasons cracks form in brickwork, including:

Settlement and foundation movement – Homes naturally shift over time, which can place stress on walls.
Water damage and rising damp – Excess moisture weakens mortar and bricks.
Rusting metal supports – Steel lintels can corrode, expand, and push against surrounding bricks.
Deteriorating mortar joints – Older mortar loses strength, leaving walls unstable.
Heavy traffic vibrations – Common in built-up or older suburbs, vibrations from roads and trains can impact brickwork.

Why Quick Fixes Don’t Work

Many homeowners try patching cracks with standard cement or filler. This only masks the problem. If the cause isn’t identified, the crack will return or spread.

The Professional Approach

At Federation Tuckpointing®, we take a systematic approach to brick wall repair:

Remove weak or damaged mortar and replace it with a strong, durable mix.
Use proven methods such as crack stitching where structural stability is required.
Replace damaged bricks with matching ones to keep the repair seamless.
Check surrounding supports, such as rusted lintels, to ensure the issue does not reoccur.

Tips for Homeowners

If cracks reach over 5mm or begin to spread, it’s time to act.
Look over and around windows and doors. These openings are supported by metal lintels, which can rust and cause cracking.
Take photos of cracks and monitor them over time.
Ask a structural engineer for a full inspection if the cracks look severe or are spreading quickly.
