How much does a building inspection cost in Melbourne?

Our pre-purchase building inspection and written report starts from $499 plus GST; a verbal building inspection report starts from $299 plus GST; meth testing starts from $279 plus GST; and pest inspection reports start from $599 plus GST. The main factors in the price are the property’s location and travel distance, along with its size, age, and construction.

Melbourne rewards an inspector who knows the local stock: a double-fronted period home with a deep subfloor takes considerably longer than a modern brick veneer, and the further you are from the city, the more travel is involved. We quote a fixed price upfront, so there are no surprises. Send the property address through our contact form, and we will confirm your price and the earliest available time. Full details are on our services page, and our guide to building inspection costs explains what you are actually paying for.

What does a Melbourne building inspection cover?

Every pre-purchase inspection covers all safely accessible areas of the property:

• Interior — walls, ceilings, floors, windows, doors, joinery, wet areas and kitchen
• Subfloor — foundations, stumps, ventilation and plumbing, where access is available
• Roof space — roof framing, insulation, wiring and the underside of the roof covering
• Roof exterior — roof cladding, fixings, flashings, gutters and downpipes
• Exterior — cladding, window and door frames, garages, decks, paving, fencing and drainage
• Moisture — metered testing around wet areas and other high-risk points

Your inspector will also note any major defects, safety hazards, and items that need further investigation. Areas that cannot be safely accessed — such as a subfloor with too little clearance to crawl into, common in older inner-Melbourne homes — are recorded as limitations in the report, so you always know what was and was not inspected. Every inspection follows the Australian Standard for pre-purchase inspections, AS 4349.1-2007. For a walkthrough of the appointment itself, see what to expect during a pre-purchase building inspection.

What will my Melbourne building report look like?

Your report will be clear, photographic and easy to act on. Findings are grouped into major defects, minor defects and maintenance items, and each one is illustrated with photos so you can see exactly what was found rather than take our word for it.

You get plain English rather than trade jargon — which matters in Melbourne, where a report may need to support a price negotiation, a building notice response or a claim against a builder — an honest summary, and practical recommendations on what needs attention and how urgent it is. We deliver reports within 24 to 48 hours of the inspection, and you are welcome to call your inspector to talk through anything in it. See reading and understanding your property assessment report.

What causes cracking in Melbourne homes — and how serious is it?

This is the single most common structural question we are asked in Melbourne, and the answer is largely about soil. Much of Melbourne’s west and north sits on the Newer Volcanics basaltic clays, which contain a highly reactive clay mineral called montmorillonite. These soils swell when they get wet and shrink as they dry, and that movement is transferred into the footings and then into the walls above them. Geotechnical work in Victoria classifies these sites as Class H or Class E — the two most reactive categories.

The Australian Standard that governs residential footings, AS 2870, classifies a site by its expected ground movement:

• Class A — negligible
• Class S — slightly reactive, up to 20 mm
• Class M — moderately reactive, 20 to 40 mm
• Class H1 — highly reactive, 40 to 60 mm
• Class H2 — highly reactive, 60 to 75 mm
• Class E — extremely reactive, more than 75 mm

Movement of that order is what produces the stepped cracking in brickwork, cracking in rendered walls, sticking doors and windows, and cracked slabs that turn up so often in Melbourne homes. It is often made worse by things that change soil moisture: poor drainage, leaking services, over-watering a garden bed against the house, raised or poorly drained fill, and trees. Trees are a well-known factor here — the standard assumes significant soil drying close to a tree, and the guidance is that a single tree keeps its influence out to roughly its mature height, one and a half times that for a small group, and twice that for four or more.

So how serious is it? A crack is not automatically a defect, and not all movement is ongoing. What matters is type, extent, pattern and whether it is still moving — whether the cracked brickwork is also out of level, whether doors and windows still operate, whether the crack has been patched and reopened, and whether the movement is consistent with the age of the building. We will tell you plainly which cracks matter, and which ones do not, and where we see something that needs engineering assessment, we will say so rather than guess.

One honest limitation: we are not structural engineers and cannot provide a footing or slab certification. Our inspection reports what is visible and gives you the evidence you need to decide whether a structural engineer or geotechnical report is warranted. See understanding structural movement in Australian homes and common building defects found in Australian home inspections.

Are there termites in Melbourne?

Yes, but Melbourne’s risk is lower than most of Australia, and the details matter more than the headline. Victoria has a lower termite hazard than the northern states, and CSIRO’s national survey found parts of Melbourne among the lowest incidence levels outside the home anywhere in the country. Some areas around Melbourne are genuinely low risk.

The important part is what the same study found inside those houses. The low outside hazard was not mirrored by a proportionately low rate of termite attack inside the buildings, and the reason given is construction rather than climate: old inner-Melbourne terrace houses were often built with minimal ground clearance and poor ventilation, so they are easily attacked. Melbourne’s inner suburbs are full of exactly that housing — solid brick terraces and weatherboards sitting low to the ground with a shallow, poorly ventilated subfloor.

So the honest position for a buyer is this: a low termite hazard zone does not protect a house that is easy for termites to get into. Damp, poorly ventilated subfloor timbers, timber in contact with soil, untended stumps and bearers, and a garden built up above the damp course all create the conditions.

Practical advice: on a Melbourne terrace or weatherboard with an old subfloor, a pest inspection is money well spent, even though the zone is not high risk. Our pest inspection reports start from $599 plus GST, are carried out to AS 4349.3, and cover all accessible areas for termites, borers, and fungal decay, along with the conditions that attract them.

Do I need to worry about combustible cladding if I’m buying a Melbourne apartment?

If you are buying an apartment or a unit in a building with a modern façade, this is worth asking about — and Melbourne is where the issue is most acute in Australia.

Two fires changed the rules here. In November 2014, a fire in the Lacrosse tower in Docklands spread rapidly up the building’s aluminium composite panel cladding and forced the evacuation of more than 400 residents; a discarded cigarette started the fire. Then in February 2019, a fire at the Neo200 building on Spencer Street in the city spread up the façade from a balcony.

The Victorian Cladding Taskforce subsequently found that combustible cladding is widely used on buildings throughout Victoria, and the VCAT decision in the Lacrosse case — which ultimately cost around $12.75 million, including make-good and compliance works — confirmed that the panels used were not compliant with the Building Code.

Victoria’s response is the $600 million Cladding Safety Victoria program. One detail matters a great deal to a buyer, because it is counter-intuitive: building owners cannot refer their own building to the program. The Victorian Building Authority Statewide Cladding Audit or the Municipal Building Surveyor at the local council refers buildings. The owners corporation then funds, designs, and project-manages rectification, and lower-risk buildings may be managed through risk-based mitigation rather than full cladding removal.

Practically, if you are considering an apartment, ask the owners corporation and the selling agent whether the building has been part of the Statewide Cladding Audit, whether it has been referred to Cladding Safety Victoria, what the outcome was, and whether any rectification work is underway or planned.

Those records sit with the owners corporation, and rectification obligations can carry a real cost for owners. It is also worth checking the minutes of recent owners corporation meetings and any building notice or order affecting the building.

One honest limitation on what we can do: a building inspection is a visual, non-invasive assessment. We can identify cladding materials, note where a façade raises a concern, and report what we can see — but establishing whether a particular panel is combustible requires sampling and laboratory testing, and a fire-safety assessment of the façade is a specialist job for a fire engineer or building surveyor. We will tell you when that is the right next step rather than assume either way.

What common defects are found during building inspections in Melbourne?

The most common findings on Melbourne properties are:

• Structural movement and cracking — stepped cracking in brickwork and rendered walls, and cracked slabs, from Melbourne’s reactive clay soils
• Footing and stump problems — stumps failing or out of level, and inadequate footings on highly reactive sites
• Subfloor defects — poor ventilation, low clearance, damp ground and timber decay below the floor, especially in older inner-suburban homes
• Rising damp and salt attack — in older solid-brick and rendered masonry, where there is no effective damp-proof course and ground levels have been raised
• Timber decay — weatherboards, window sills, door joinery and subfloor timbers, driven by wet winters and poorly ventilated subfloors
• Roof and gutter defects — deteriorated roof cladding, perished or corroded fixings, failed flashings, blocked gutters and leaking box gutters
• Asbestos-containing materials — common in wet areas, eaves and cement sheeting in homes built before 1990
• Non-compliant or unapproved building work — including DIY renovations, unpermitted extensions and carports, and converted garages
• Waterproofing failures — leaking balconies, showers and wet areas, particularly in apartments and newer homes
• Safety hazards — unsafe balustrades, stairs, glazing, and electrical or gas fittings

Our guide to common building defects found in Australian home inspections covers each of these in more detail.

Do I need a building inspection for a new home in Melbourne?

Yes, and in Melbourne there is a second reason to take it seriously. New and recently built homes can still have defects, including incomplete work, work that does not meet the required standards, and problems that only show up after the first winter.

The Melbourne-specific part is the ground it is built on. Because the western and northern growth corridors sit on highly reactive basaltic clay, the site classification for a new build matters, and a site classification applies to a site, not to a suburb — two blocks on the same street can be classified differently, and a classification must be based on geotechnical testing and desk study rather than an assumption about the area.

There is also genuine professional debate about whether the standard AS 2870 raft designs perform adequately on the most reactive H2 sites, with published geotechnical research finding waffle rafts substantially less robust than stiffened rafts on that ground. That is a discussion for your engineer and builder, not an inspector — but it is worth knowing that on a Melbourne growth-corridor block, footing design isn't a formality.

On top of that, the inspection itself matters. Problems that only reveal themselves in the first winter — water finding its way past flashings and seals, wet-area waterproofing that was never quite right, and drainage that does not cope with the site — are best caught before settlement, while they are still the builder’s responsibility.

A practical inspection during construction is worth considering as well as the final one, because much of what later fails is hidden once linings go on. Our guide to planning your new home construction timeline in Australia shows where the inspections fit into the build.

How long does a building inspection take in Melbourne, and when will I get the report?

Most residential inspections take one to two hours, depending on the property’s size, age and construction, and how accessible the subfloor and roof space are. A large period home in the inner suburbs, or a house with a deep subfloor and a complex roof, can take longer — we would rather spend the time than rush a section. Your written report follows within 24 to 48 hours.

If you are working to an auction, a finance deadline or a cooling-off period, ask about a verbal summary on the day so you are not waiting on the written report to make a decision.

Can I attend the building inspection?

Yes, and we encourage it. Attending gives you the chance to see the issues for yourself, ask questions on the spot, and understand how serious each one really is — which is particularly useful on a Melbourne home with structural cracking, where the difference between normal ageing and ongoing movement is best explained on site with the wall in front of you.

If you cannot attend — because you are interstate, overseas, or simply short on time — your inspector will call you through the findings, and everything is documented in the report with photos.

Are your Melbourne building inspectors qualified?

All of our inspectors are trade-qualified builders with hands-on construction experience, not just trained observers. That matters in Melbourne because the housing stock is unusually varied — solid-brick Victorian terraces, weatherboards on stumps, mid-century brick veneer, and modern slab-on-ground construction in the growth corridors all fail in different ways.

An inspector who understands how each of those was built can tell the difference between a cosmetic crack and a structural one. Every inspection follows the Australian Standard for pre-purchase inspections (AS 4349.1-2007), each inspector carries professional indemnity insurance, and all major banks accept our reports. You can meet them on our team page.

What is a builders report, and is it the same as a building inspection?

Yes — they are the same thing under two different names. “Builders report” is the term most people use in conversation and in some parts of Australia, while “pre-purchase building inspection” is the formal description used in the Australian Standard (AS 4349.1-2007). Whichever you ask for, you get the same thorough, non-invasive, trade-qualified inspection of the property’s condition, and the same written report. If a lender, conveyancer, or real estate agent tells you you need a builder's report, this is what they mean.

What is the difference between a building inspection and a pre-listing inspection?

A pre-purchase building inspection is ordered by the buyer to find out what they are buying before they commit. A pre-listing inspection is the same inspection the seller orders before going to market, so they know what will come up, can fix what is worth fixing, and can price the property with their eyes open. Both follow the same Australian Standard and produce the same style of report. We carry out both across Melbourne and regional Victoria.

Is asbestos a concern in older Melbourne homes?

Yes. A large share of Melbourne’s housing was built before asbestos-containing materials were phased out, and as a rule of thumb, any home built before 1990 should be assumed to contain asbestos cement products—commonly known as “fibro”—unless evidence shows otherwise. In Melbourne houses, it most often turns up in wet-area wall sheeting, eaves and soffits, ceiling sheeting, roof sheeting, fencing, and occasionally in insulation.

Asbestos-containing materials are not inherently dangerous when intact and undisturbed. They become a real risk when they are cut, sanded, drilled, broken or allowed to deteriorate. That matters on a purchase because Melbourne’s period housing is often bought with renovation in mind: a weathered fibro sheet on an old eave or shed, or sheeting behind bathroom tiles, is exactly the kind of thing that needs identifying before demolition starts, not during it. Victoria also has specific requirements for asbestos removal and disposal, and renovation waste containing asbestos must be handled by a licensed removalist.

Our inspectors identify materials likely to contain asbestos and flag them in the report, but we do not test — sampling is a separate service carried out by a licensed asbestos assessor, and we will tell you when that is the right next step. See asbestos in Australian homes: identification and safety guide and asbestos timelines in Australian homes.

Where do you inspect in Melbourne?

We inspect properties right across greater Melbourne. Areas with their own dedicated pages include Craigieburn, Point Cook, Pakenham, Reservoir, Tarneit, Berwick, Werribee, Glen Waverley, Richmond, Brunswick, Narre Warren, South Yarra, Doncaster, Cranbourne, Hawthorn, Southbank, Sunshine and St Kilda. If your suburb isn't listed, send your address through, and we will confirm straight away. We also inspect throughout Australia, with locally based, trade-qualified inspectors in Sydney, Perth, Adelaide, Canberra, Darwin and Tasmania.

What happens if the Melbourne report finds significant defects?

The report gives you the facts you need to decide, not a recommendation to walk away. Depending on what is found and how the property is priced, buyers commonly use a report to negotiate a lower price, ask the vendor to complete repairs before settlement, obtain a specialist assessment — a structural engineer, a geotechnical report, or an asbestos or damp specialist — or withdraw if the risk is unacceptable.

In Victoria, your rights to withdraw depend on the conditions in your contract, so seek legal advice before acting on that option. If you are comparing inspectors, how to choose the right building inspector sets out what actually matters. Our inspectors remain available to talk through the findings after delivery — a report is only useful if you understand it.
