A surprising number of buyers assume that once they have booked a building inspection, termites are covered too. It is an easy assumption to make, the two are often quoted together, booked on the same day, and rolled into one conversation with the agent. They are not the same inspection, they do not follow the same standard, and skipping one because you have already booked the other is one of the more expensive mistakes a buyer can make.
What a Building Inspection Actually Assesses
A building inspection, carried out to AS 4349.1-2007, looks at the structural condition and safety of the property, things like the roof, walls, subfloor, and site. It is thorough within its scope, but that scope specifically does not include timber pests. We go into this standard in detail in our article on what AS 4349.1 actually requires, but the short version is that a clean building inspection report tells you nothing at all about whether termites are present.
What a Termite Inspection Actually Assesses
A pre purchase termite inspection, sometimes called a pest inspection or timber pest inspection, is carried out to a completely different standard, AS 4349.3-2010. It is specifically looking for subterranean termites, wood borers, and fungal decay, along with the conditions that tend to attract them, moisture, poor ventilation, and timber sitting in contact with soil. We cover what this actually involves in our article on what AS 4349.3 covers, but the key point here is that it requires its own trained eye, looking for entirely different evidence than a structural inspector is trained to notice.
Why One Doesn’t Replace the Other
Termites can be actively damaging a property’s structural timber while the building itself still looks, and structurally is, perfectly sound. A wall can be free of cracking, a floor can feel level, and a roof can look immaculate, while termites work through a bearer underneath the house entirely undetected by anyone not specifically looking for the mud tubes, hollow sounding timber, or moisture patterns that give them away. A qualified building inspector is trained to assess structural soundness. A qualified termite inspector is trained to find termites. Overlap between the two is smaller than most buyers assume.
Different Training, Different Tools
The two inspections do not just look at different things, they are carried out differently. A building inspector works with a level, a torch, and a trained eye for cracking patterns, sagging, and movement. A termite inspector relies on moisture meters and sounding tools to detect activity hidden behind an intact looking surface, along with knowledge of exactly where termites like to hide, subfloor timber, retaining walls, garden beds hard up against the house, and the thirty metres or so of surrounding property that falls within a proper termite inspection’s scope. It genuinely is a different skill set applied to a different problem, which is why one inspector covering both needs to be qualified in both areas, not just assumed to be.
What Termites Can Do Before Anything Looks Wrong
This is really the heart of the issue. Termites are built to avoid detection, they dislike light and disturbance, and a colony can work through structural timber for years before any visible sign appears on the surface. By the time a building inspection would pick up on sagging or movement caused by termite damage, the timber loss is often already extensive and expensive to repair. A termite inspection is designed to catch the problem at the mud tube and moisture stage, well before it becomes a structural issue a general building inspection would notice.
The Financial Reality
Standard Australian home and contents insurance typically excludes termite damage altogether, treating it as a preventable maintenance issue rather than a sudden, insurable event. That means if termite damage turns up after you have settled on a property, the repair cost is almost always yours alone to cover, regardless of how sound the rest of the building is. We go into this in more depth in our article on AS 4349.3, but it is worth repeating here because it is the single biggest reason skipping the termite inspection to save on the day is usually a false economy.
When You Might Genuinely Get Away With Just One
To be fair to buyers who ask, there are situations where the termite risk is genuinely lower. A high rise apartment well above ground level, with no direct timber contact to soil and no garden of its own, carries a much lower termite exposure than a standalone house with a subfloor and established garden beds against the walls. In those cases, a building inspection alone may be reasonable, though we would still recommend asking about the building’s overall pest history before deciding. For anything with its own land, timber subfloor, or garden contact, we would not recommend skipping the termite side.
Booking Both Together
For most established houses and townhouses, the practical answer is simply to book both on the same visit. It usually works out more cost effective than two separate appointments, and it means one qualified engineer and certified termite inspector is looking at the whole picture, rather than two separate reports that might miss each other’s context.
Frequently Asked Questions
Q. If my building inspection found no major defects, does that mean there’s no termite risk?
No. A building inspection report says nothing about termite activity one way or the other, since that is outside its scope entirely. The two findings are genuinely independent of each other.
Q. How much more does it cost to add a termite inspection?
Less than booking it separately later. Combining a building and pest inspection on the same visit is generally discounted compared to arranging two separate appointments, and it saves you organising a second visit to the property.
Q. Can termites be present without any visible signs at all?
Yes, and this is exactly why the inspection exists. Termites are built to avoid detection, and a colony can be active inside structural timber for a long time before anything becomes visible without specifically looking for it.
Q. Is a pre purchase termite inspection the same as ongoing pest control?
No. A pre purchase termite inspection is a one off assessment of the property’s condition on the day, for the purpose of informing your purchase decision. Pest control is a separate, ongoing service for treating or preventing infestation once you own the property.
Q. Does every property need a termite inspection, even new builds?
Generally yes. New homes are not immune, termites do not care how old a building is, only whether there is timber and moisture available. If anything, checking early gives you the best chance of catching a problem before it has had time to spread.
Q. What about a townhouse with a small shared garden?
Shared gardens and common property still carry termite risk, particularly where garden beds or mulch sit close to the building’s timber. It is worth checking with the body corporate about any past pest history for the complex, in addition to your own inspection of the unit itself. Melbourne’s continued growth in medium density townhouse living, particularly across the middle and outer suburbs, means more buyers are looking at properties built close together on smaller blocks, often with shared or tightly packed garden beds hard against multiple units. That proximity does not increase termite risk on its own, but it does mean that if one unit in a row has an issue, it is worth understanding whether neighbouring units share timber framing or party walls that could be affected too.
