Building and pest inspection: what each report covers and why you need both before you buy

A building inspection and a pest inspection are two different licensed jobs

Most people hear 'building and pest inspection' and think it's one job. It isn't. It's two. A licensed building inspector looks at the structure: roof, walls, foundations, drainage. A licensed pest controller checks for timber pest activity. Different licence, different scope. 1qbcc.qld.gov.auView source

Here's the problem if you only get one. The building report can note old termite damage as a defect. But it can't tell you if those termites, or others, are still active today. Only a pest controller can answer that. 2nsw.gov.auView source

NSW Government puts it plainly: the building report 'won't include whether termites and other pests that destroy timber are still around.' A clean building report doesn't mean a clean pest report. You need both. 2nsw.gov.auView source

What a pre-purchase pest inspection actually covers

A pest controller checks for three things: active timber pests, signs of past damage, and any termite barrier or bait system on the property. If a barrier is in place, the report notes whether it still looks intact. 1qbcc.qld.gov.auView source

To find pests that aren't visible, inspectors use a torch, a sounding tool (called a donger), a moisture meter, and sometimes a thermal camera. High moisture often means termites are near. A thermal camera can pick up heat from a colony in a wall or under the floor. 3business.qld.gov.auView source

The check is non-invasive. No walls are opened. No floors are lifted. The pest controller looks at areas they can reach. That matters. A clear report means no pests were found where they could look. It doesn't mean the home is pest-free.

Buying in a high-risk area? Many parts of coastal and tropical Australia are. Your pest controller can flag whether a deeper look is worth it.

Two Australian Standards govern timber pest inspections

There are two different Australian Standards for timber pest inspection work. Which one applies depends on whether you're buying a property or maintaining one you already own.

Make both inspections a condition of your contract

QBCC is clear: get both reports before you sign, and make both a contract condition. If a report finds something you're not happy with, you can walk away or ask for a lower price. 1qbcc.qld.gov.auView source

NSW Government adds one more point. A vendor can hand you their own report. That's not the same as yours. Their inspector works for them. Yours works for you. 2nsw.gov.auView source

When you book your own pest check, you can talk to the pest controller after. Ask what they found, how bad it is, and what fixing it might cost. That chat is part of what you pay for.

If active pests or old damage shows up, a licensed pest controller can run you through what to do next. SureQuote connects you with controllers who can both inspect and quote on any follow-up work.

What a clear pest report actually tells you

A clear report means no pests were found in the areas the inspector could reach. That's it. Pre-purchase checks don't open walls or lift floors. Wall gaps, under-slab areas, and tight roof spaces stay closed.

Still worried about one area? Ask. The pest controller can tell you if it's worth a closer look before you sign.

A pest report is also a snapshot in time. Termite activity can show up fast after a clear report. If you're in a risk area, ask your pest controller how often to re-check and whether a termite barrier makes sense.
