Pre-purchase pest inspection: what you are really buying
A clear report is a snapshot of the areas the inspector could reach. Here is how to read it and how to get more out of it.
The inspection you book before you are the owner
A pre-purchase pest inspection is a timber pest inspection done on a house you are thinking of buying, before the contract goes unconditional. Its job is simple. It tells you what evidence of termites, borers and fungal decay the inspector could see on the day, and what they could not reach.
It does not tell you the house is free of termites. That distinction decides whether the report protects you or just reassures you.
What the report can and cannot tell you
| The report can tell you | The report cannot tell you |
|---|---|
| Visible evidence of activity or past damage in the areas that were accessible | That termites are absent from walls, roof voids or subfloors that were blocked or sealed |
| Conditions that favour termites, such as damp, timber touching soil or poor subfloor ventilation | Whether a colony will find the house next year |
| Which areas were inspected and which were not | The full extent of any damage hidden behind linings |
| A recommendation for further investigation where something looks wrong | Which species is involved, unless a specimen is examined by the inspector |
Read the second column twice. It is where buyers get caught.
The limitations section matters more than the verdict
A report that says "no evidence found" sounds like good news. Turn to the limitations first. A full roof void, a locked shed, a subfloor too low to crawl into or furniture stacked against every wall all shrink what "no evidence" really covers.
If a large part of the building was not inspected, you have a decision. You can ask the seller to clear access and book a second visit, or you can price the unknown into your offer. Waving it through is the one choice not worth making.
Is it the same as a building and pest inspection?
Not quite. A building inspection looks at structure and finishes. A timber pest inspection looks for termites, borers and decay, and in Australia it is meant to follow AS 4349.3. Many companies sell the two together, and that can be convenient. The pest part should still stand on its own, with its own limitations and its own named inspector.

How to get more out of it
- Check the inspector holds the licence your state requires for timber pest work.
- Ask which standard the report follows, and whether it will name the areas not inspected.
- Ask for access to the subfloor and roof void to be arranged before the day, not on it.
- Be there if you can. An inspector will often point out things that never reach the written report.
- Ask what the inspector would recommend if you buy, such as an inspection schedule and conditions to fix.
If the report finds evidence
Evidence is not automatically a reason to walk away. It is a reason to find out more. Ask the inspector what they saw, where it sits and whether further investigation is recommended. Then take that to the people qualified to advise you on the contract and any insurance, because interpreting a contract or a policy is outside what this guide can do.
One rule holds in every case. If you see a mud tube, hollow timber or swarming insects during an inspection, do not touch them or spray them. Disturbed termites abandon that route and re-enter somewhere hidden, and you destroy the evidence the report depends on. Leave it for the inspector.
A clean report is a snapshot
Even a good result describes one day. After you move in, termite risk depends on the barrier, the garden, damp and the house's age. Plan for regular inspections from the start, and see how often to inspect for what that usually means.
Timing, and the pressure to skip it
The inspection is most useful before the cooling-off period or any finance and inspection condition runs out. Once the contract is unconditional, a bad report gives you very little to act on. If the timetable is tight, ask early rather than late, and do not let a busy market talk you out of it.
Sellers sometimes offer a report they commissioned themselves. Read it, but remember who paid for it and when it was done. A report is a record of one day, and a newer one for your own purposes is usually the safer choice.
How to read a pre-purchase pest report, section by section
Start with what the inspector could not see, not with the verdict. A clear result only covers the areas that were reached on the day. Read the report in this order.
- The limitations section. Note every area listed as not inspected: a full roof void, a locked shed, a low subfloor, walls hidden by furniture. This tells you how much "no evidence found" really covers.
- The areas inspected. Check that the subfloor and roof void appear here. If they do not, ask the seller to clear access and book a second visit, or price the unknown into your offer.
- Conditions that favour termites. Damp, timber touching soil and poor subfloor ventilation are not activity, but they are what you will be managing once you own the house.
- Evidence of activity or past damage. If there is any, ask the inspector what they saw, where, and whether further investigation is recommended.
- The recommendations. These usually cover further investigation, conditions to fix and an inspection schedule after you move in.
- Who signed it and to what standard. Look for a named inspector holding your state's licence for timber pest work, and a report that follows AS 4349.3.
Contract and insurance questions go to your conveyancer or insurer. For what a full inspection should include, see what a termite inspection covers.
Frequently asked questions
What is a pre-purchase pest inspection?
It is a timber pest inspection carried out on a property you want to buy, before you commit. It reports visible evidence of termites, borers and decay in the areas the inspector could access, and lists the areas they could not.
Does a clear report mean the house has no termites?
No. It means no evidence was found where the inspector could look on that day. Blocked or sealed areas are listed in the limitations section, and termites can be present in places that were not checked.
Is it the same as a building and pest inspection?
Not exactly. A building inspection looks at structure and finishes, while a pest inspection looks for termites, borers and decay. Many companies sell them together, but the pest part should have its own scope and limitations.
What should I do if the report finds termite evidence?
Ask the inspector what they saw and whether further investigation is recommended. Take contract and insurance questions to a conveyancer or the insurer. Do not touch, break or spray anything you see.
