Properties, like people, age over time. As houses grow older, the materials used in their construction begin to show signs of wear. Bricks may crack, timber may warp, and steel may rust. These issues are not always obvious on the surface and can remain hidden until they become serious. That is why regular structural inspections are important, especially for homes that are decades old.
Knowing when to book a structural check can help avoid major repairs in the future. In this article, we will look at how often these inspections should take place, what signs to look out for, and how they help keep homes safe and stable.
What Is a Structural Inspection?
A structural inspection involves a thorough check of a building's structure. This includes walls, floors, roof frames, foundations, support beams, and load-bearing elements. The goal is to make sure the property is still strong and safe.
These inspections are not just for people buying a new home. Property owners should also schedule them at different stages during the life of a building, especially as it ages.
Why Older Homes Need More Attention
Older properties, particularly those built more than 30 years ago, were often constructed using materials and methods no longer in use today. Some of these materials may weaken over time, while others may not meet current safety standards.
For example:
-
Timber frames may suffer from termites or moisture damage
-
Brickwork may start to shift or crack due to movement in the ground
-
Roof structures may sag due to water damage or decay
-
Concrete may become brittle with age
These changes do not happen overnight, but when left unchecked, they can lead to serious problems. That is why regular checks are necessary.
How Often Should You Arrange One?
There is no fixed rule that applies to every property, but general advice from Australian building professionals suggests the following:
-
Every 10 years: For homes older than 30 years, a full structural inspection should be carried out every decade.
-
Every 5 years: For homes older than 50 years, especially if they are built on sloped land, made of timber, or located in high-rainfall areas.
-
After natural events: Following floods, storms, or earthquakes, even if no clear damage is seen.
-
Before major renovations: If walls will be removed, floors replaced, or large changes made to the building layout.
Regular inspections can pick up slow-developing issues before they turn into major repairs. They also help property owners plan ahead and maintain the building safely.

What Are the Signs You Might Need One Sooner?
While regular checks are advised, there are some signs that should not be ignored. If you notice any of the following, it is wise to book an inspection sooner:
-
Cracks in walls or ceilings
-
Uneven or sloping floors
-
Doors or windows that no longer shut properly
-
Sagging rooflines
-
Water damage or rising damp
-
Gaps between walls and ceilings or floors
These symptoms might seem small at first but often point to movement or weakness in the building's frame or foundation.
Not Just for Buyers or Sellers
Many people think inspections are only needed when buying or selling property. While those are common times, regular checks help even those who plan to stay in their home for years. They allow you to plan repairs before they grow larger, and often help avoid emergency work later on.
Even rental property owners should keep records of structural checks, especially for older buildings, to meet safety responsibilities and protect tenants.
Why Location Matters
Some areas are more prone to soil movement, flooding, or termite activity. In Brisbane, for example, the soil type in some suburbs can lead to more foundation shifts over time. This means homes in such areas may require more frequent inspections.
Also, buildings near the coast often face moisture and salt exposure, which can affect timber and metal parts more quickly.
When Planning Other Inspections
If you are planning a general building report or preparing for major repairs, this can be a good time to include a structural check. Pairing it with other assessments can give you a full picture of your property's condition.
For those managing multiple properties or investment homes, regular scheduling across all sites helps maintain consistency and prevents surprises.

Final Thought
All homes grow older, but not all show signs clearly. That is why knowing when to book a structural inspection is important. It keeps people safe, protects your property, and can help reduce larger repair costs later on.
For older homes, the message is clear: do not wait for a problem to appear. Regular checks every few years, or sooner if issues arise, can make all the difference in how long your home stays strong and stable.
