Hiring a building inspector is one of the smartest moves you can make before buying a home, renovating, or checking on building work in progress. A good inspector can spot structural issues, moisture problems, safety concerns and hidden defects that may cost you later. But not all inspectors offer the same level of experience, reporting style or local knowledge.
Before you book anyone, it pays to ask a few targeted questions. That helps you understand what they inspect, how they report, and whether they are the right fit for your property and your state or territory requirements.
Check Their Qualifications And Local Knowledge
In Australia, building inspection work is not a one-size-fits-all service. Different states and territories have different licensing or registration rules, and a reputable inspector should be able to explain how they meet them. If they are also a builder, ask what building licence they hold and whether that licence is current. You can also check with your state’s building regulator, fair trading body or licensing authority.
Ask these questions early:
- Are you licensed or registered to carry out building inspections in my state or territory?
- How long have you been inspecting homes in Australia?
- Do you specialise in pre-purchase inspections, defect inspections, handovers or renovation checks?
- Have you inspected homes of this age, construction type and suburb/climate before?
Local knowledge matters. An inspector who understands Australian conditions will know to look closely for issues such as rising damp in older homes, poor subfloor ventilation, corrosion in coastal areas, heat-related movement, termite activity, or storm damage after severe weather. They should also be familiar with the National Construction Code and common Australian building methods, including brick veneer, timber framing, concrete slab homes, and cladding systems such as James Hardie or similar fibre cement products.
Ask What The Inspection Covers
Not every building inspection includes the same scope. Some inspections focus on obvious structural and safety issues, while others are more detailed and include roof cavities, subfloors, external drainage, retaining walls, wet areas and accessible services. Always ask what is included before you hire them so you know exactly what you are paying for.
Useful questions include:
- What parts of the property do you inspect, and what is excluded?
- Do you inspect the roof space, subfloor, fencing, garage and outbuildings?
- Will you check for signs of water ingress, mould, cracking, movement and timber decay?
- Do you use moisture meters, thermal imaging or other tools if needed?
- Do you inspect for termite activity or only note visible damage?
If you are buying a home, a pre-purchase inspection should help you understand the property’s condition, not just list cosmetic faults. If you are renovating, you may need a more specific defect assessment. For example, if you are planning new plasterboard work with Gyprock/CSR, external cladding, a Colorbond roof replacement or a bathroom upgrade, the inspector should be able to flag issues that might affect your project before you engage other trades.
Understand How They Report And Communicate
A good building inspector should explain findings in plain English, not hide behind jargon. Ask to see a sample report so you can judge whether it is clear, photo-based and practical. You want a report that tells you what was found, where it was found, and why it matters.
Ask these questions:
- Can I see a sample report?
- Will the report include photos and plain-language explanations?
- How soon will I receive the report after the inspection?
- Do you offer a follow-up phone call to discuss the findings?
- Will you explain which issues are urgent and which are routine maintenance?
It is also worth asking how they handle serious defects. For example, if they identify possible structural movement, significant moisture damage, unsafe stairs or illegal alterations, you want someone who can explain the risk clearly and recommend the next step. A strong inspector will help you decide whether to seek advice from a builder, structural engineer, plumber, pest specialist or other licensed professional.
| Question Area | What You Want To Hear |
|---|---|
| Qualifications | Current licence or registration, plus relevant inspection experience |
| Scope | Clear list of what is and is not inspected |
| Reporting | Photo-rich report with practical explanations |
| Follow-up | Opportunity to discuss findings in plain English |
| Independence | No conflict of interest with the sale, build or repair work |
Ask About Independence, Insurance And Safety
Independence is important. If an inspector is also trying to sell repairs, manage the sale, or direct you to a business they are financially tied to, their advice may not be as objective as you expect. Ask whether they have any conflicts of interest and whether they are truly independent.
You should also ask about insurance:
- Do you carry professional indemnity insurance?
- Do you have public liability insurance?
- What happens if something is missed in the report?
On the safety side, a building inspector should never ask you to ignore obvious hazards. If the property has exposed wiring, unsafe stairs, damaged balustrades, active leaks, or other risks, those issues should be clearly noted. Remember that electrical work, gas fitting and many plumbing tasks in Australia must be carried out by a licensed professional, not a general handyman or unlicensed contractor.
If the inspector recommends further investigation, ask who should do it. For example, electrical faults should go to a licensed electrician, gas concerns to a licensed gas fitter, and plumbing issues to a licensed plumber. Safe Work Australia guidance also supports working safely around hazards, so a careful inspector should not encourage unsafe access or dodgy shortcuts.
Final Checks Before You Book
Before you confirm the inspection, ask how long the job will take, what access they need, and whether you need to arrange keys, roof access or permission for pets. Also check whether they service your type of property, such as strata units, heritage homes, townhouses or rural homes with sheds and tanks. If you are comparing inspectors, look at the quality of their answers rather than just their availability.
A few final questions can save you a lot of stress later: would they be prepared to explain a report to you after hours, do they understand Australian building materials and weather conditions, and will they give you practical advice you can act on? The best building inspectors are thorough, independent and easy to talk to.
For extra peace of mind, you can also compare the advice you receive with guidance from reputable Australian suppliers and manufacturers such as Bunnings, Mitre 10, Dulux, Taubmans, British Paints, BlueScope and CSR when it comes to maintenance products and common repair systems.
