Buying a home is one of the few times you commit to a building you have only walked through briefly. A pre-purchase inspection is the independent look that fills in what the open inspection could not: the roof space, the subfloor, the base of the walls behind the furniture, and the small signs that point to water, movement or timber pests.
This guide sets out what the inspection covers, what the timber pest part looks for, what you receive, and what sits outside the scope. It is part of our series on inspections before buying a home in Victoria, which covers the wider set of checks a buyer may want to make.
What is a pre-purchase inspection?
A pre-purchase inspection is a visual, non-invasive inspection of a home's accessible areas, including a look for visible signs of timber pest activity, set up around a purchase. You commission it for your own information before you commit, and the report describes what was observed on the day.
Two things define it. It is independent: we are not the vendor, the agent or the builder, and we have no stake in whether the sale goes ahead. And it is visual: nothing is opened up, no linings are removed and nothing is tested destructively. What can be seen is reported; what cannot be seen is listed as a limitation.
It is not a statutory inspection. The mandatory inspections carried out for a building permit are done by or on behalf of the relevant building surveyor, and they belong to the permit process. A pre-purchase inspection is separate from those and does not replace them.
If you already own the home, the same inspection is offered as a building and pest inspection. The approach is identical; the difference is that a purchase has dates and a seller's agent in the picture.
Which parts of the home are inspected?
The inspection moves through the home area by area, covering what is accessible:
- The interior: walls, ceilings, floors, windows and doors in each room, with attention to cracking, staining, sagging, sticking doors and signs of past repair.
- Wet areas: showers, baths, vanities and laundries, where water damage tends to show first, including the floor around them and the ceiling below where there is a storey underneath.
- The exterior: external walls, cladding, eaves, visible roofing and roof plumbing as seen from the ground or another safe vantage point, downpipes and the ground close to the walls.
- The roof space, where a hatch gives safe and reasonable access: the underside of the roof, framing, insulation as visible, signs of water entry and signs of timber pest activity.
- The subfloor, where there is an opening and it is safe to enter: bearers, joists, stumps or piers, ventilation, moisture, debris and timber in contact with soil.
- Site elements close to the home, as agreed in the scope: paths, driveways, retaining walls, fences, steps, decks, pergolas and outbuildings.
Each area is described as it was found. Furniture is not moved, carpets are not lifted, and locked or packed rooms are recorded as not inspected. The more of the home that can be reached on the day, the shorter the list of limitations.
What does the timber pest part look for?
Timber pest activity, including termites, is common across Victoria, in established suburbs as much as on the fringe. The inspection looks in the accessible areas for visible signs: damaged or hollow sounding timber, mud leads and workings, frass, old treatment evidence, and borer holes in flooring or framing.
Just as important are the conditions that make activity more likely. Moisture under the house, poor subfloor ventilation, timber in contact with soil, garden beds built up against walls, firewood stacked against the house and leaking plumbing all raise the risk, and the report notes them so you know what to deal with if you buy.
The limits are real. Activity can be concealed inside timber, behind linings or in areas with no access, and the report cannot confirm that a home is free of timber pests. Where the signs call for it, the report can recommend a specialist timber pest investigation or treatment.
What do you receive after the inspection?
You receive a written report that describes what was observed at the time, area by area, with photos supporting the key observations. It includes a clear list of areas that could not be inspected and why, so you know where the gaps are. Items you may want to ask the agent about, or have a specialist look at, are noted in plain language rather than buried in jargon.
We also talk the report through with you. The conversation is often as useful as the document, because it sorts the routine maintenance items from the ones that deserve a closer look before you decide. Where an observation needs another professional, the report says which kind: a structural engineer for cracking and movement, a licensed plumber for drainage, a licensed electrician for wiring.
The report describes the home on the day of the inspection. Conditions change, timber pest activity can start later, and a report is not a warranty, an insurance policy or a certificate of compliance.
What does a pre-purchase inspection leave out?
Being clear about the edges helps you plan the rest of your checks:
- It is not a valuation, and it does not advise on whether to buy or what to pay.
- It cannot see behind walls, under floor coverings or into concealed, obstructed or unsafe areas, and defects may exist there.
- It does not test appliances, heating, hot water, plumbing or electrical systems. Visible defects are noted; performance is a matter for the relevant trade.
- It is not a structural engineering assessment. Where cracking or movement is significant, a structural inspection or an engineer's assessment is the next step.
- It does not confirm whether permits were obtained for extensions or alterations. It can note visible additions so that you or your conveyancer can ask the vendor or check with your council; our guide to which permits building work needs in Victoria explains what to look for.
- It does not test for asbestos or mould. Materials that may contain asbestos and visible mould can be noted, and a separate inspection can be arranged where it is warranted.
- For an apartment or unit, the common property and the owners corporation papers are a separate layer. A strata report is shaped for that, and our guide to buying an apartment or unit in Victoria explains how the two fit together.
How does it fit with your other checks before buying?
A pre-purchase inspection is one input among several. Your conveyancer or lawyer reads the contract and the vendor's statement and advises on conditions, cooling off and timing. Your lender may want a valuation. The agent can answer questions about the home's history and arrange access for a second look at anything the report flags.
Timing is the practical issue. Many buyers inspect before auction day or make a private sale contract subject to inspection; your conveyancer can tell you which conditions apply to your purchase. When you enquire, tell us the date you are working to and we will let you know what can be arranged. Access is organised with the selling agent, and it is worth asking the agent in advance whether the roof hatch, the subfloor opening, the meter box and any outbuildings can be opened on the day.
If you can be there, come. You can point out what worried you at the open inspection, and we can show you what we are seeing as we go.
