Common Structural Issues in Older Perth Homes (And What to Do)

Coastal Perth homes often face unique structural challenges over time.

Perth has no shortage of charming older homes, but with age comes structural wear and tear. Identifying issues early is the key to protecting both safety and property value. Here are some of the most common structural problems and what to do if you notice them.

Subsidence and foundation movement

Many older homes were built on soil types prone to movement. Signs of subsidence include uneven floors, sticking doors, or visible gaps around windows. Left unaddressed, these can worsen over time.

Cracks in walls

Not all cracks are cause for alarm, but wide or expanding cracks—especially near corners or above windows—may indicate structural stress. An engineer can determine whether they’re cosmetic or structural.

Roof and ceiling issues

Sagging rooflines, bowed ceilings, or water damage are common in older properties. Structural assessment ensures that the load-bearing members are safe and compliant with current standards.

Corrosion and timber decay

Steel corrosion and timber rot are common in homes exposed to Perth’s coastal climate. These issues weaken the home’s structure and should be identified and repaired promptly.

What to do next

If you notice any of these signs, engaging a structural engineer is the safest step. They’ll carry out an inspection, identify root causes, and provide a report with clear recommendations for remediation. This not only addresses immediate concerns but also prevents minor problems from becoming major expenses.

Owning an older home doesn’t mean compromising on safety. With the right engineering advice, you can preserve its character while ensuring it remains sound for years to come.
