How long does a building and pest inspection take?
Quick is not the same as careful. The time on site is one of the few things you can check for yourself.
The usual answer: a few hours on site
For an average house, a building and pest inspection typically takes a couple of hours on site, sometimes longer when both parts are done together. The written report usually arrives later, often within a day or two of the visit. Ask your inspector for their own estimate, because it varies with the property.
Treat any figure as a guide. What matters is that the time matches the size and difficulty of the house.
What makes it take longer
- Size and layout: more rooms, more levels, more outbuildings.
- Access: a tight subfloor or a roof void with an awkward hatch slows everything down.
- Age and condition: older houses and those with past repairs need more probing.
- Both inspections at once: the building and timber pest components are separate jobs, even when one visit covers them.
- The site: a large block with sheds, decks and retaining walls adds more to check.
What a very short visit can mean
A fast inspection is not automatically a poor one. A small unit with easy access can be done quickly. But a large house with a subfloor and roof void, done in a fraction of the expected time, is worth a question.
Ask where the inspector went, which areas they entered and which they only looked into. The report's list of inaccessible areas should be consistent with what you were told.
Should you attend?
If the inspector agrees, being there for the last part is often useful. You can ask what each finding means in plain terms, and see the evidence in person. You do not need to follow them under the house.
Do not rush them, and do not ask them to skip an area to save time. That is the wrong place to be efficient.
Plan around the report, not just the visit
The on-site time is only part of the clock. Reports take time to write, and your contract may give you a short window. Book early, before you are under pressure. Then ask the inspector to call you with the headline findings the same day.
What the report means for your contract is a question for a conveyancer or solicitor, not for us. Ask early rather than at the deadline.
If the report finds termites
Leave the area untouched. Spraying or breaking mud tubes can make the colony move and hide, and it destroys evidence the inspector uses. Ask who is licensed to inspect further in your state.
Frequently asked questions
How long does the report take to arrive?
It varies by inspector and by how busy they are. Many deliver within a day or two, but ask when you book, especially if your contract has a short deadline.
Is a longer inspection always better?
Not always. A small, easy-access property can be done quickly. What matters is that the time fits the size and access of the house.
Can I ask the inspector to check an area they skipped?
Yes. Ask why it was skipped and what it would take to see it. Sometimes it needs a hatch opened or items moved, and a return visit can be arranged.
