What Factors Affect the Price?
Several things influence how much a plumbing inspection will cost:
Size of the property: Larger homes with more bathrooms, laundries, and outdoor taps naturally take longer to inspect.
Age of the home: Older properties often have more complex or deteriorated plumbing systems, which require more thorough assessment.
Whether CCTV drain inspection is included: A drain camera inspection adds time and specialist equipment to the job, which is reflected in the price — but it’s also one of the most valuable parts of any pre-purchase inspection.
Access and property layout: Difficult access to subfloor areas, tight drainage cleanout points, or multi-storey layouts can affect the time required.
Combined vs. separate inspections: Booking a plumber and gas fitter together through the same company is almost always more cost-effective than arranging them separately.
Is It Worth It?
To put the cost in perspective: the average plumbing inspection in Brisbane costs less than 0.1% of the purchase price of a typical home. For that, you get a detailed assessment of systems that, if they fail after settlement, can cost anywhere from $3,000 for a hot water system replacement to $25,000 or more for major drainage repairs or slab leak remediation.
Even if the inspection comes back clear, that information has value — it confirms you’re buying a home without hidden plumbing liabilities.
| Pre-purchase inspections can also be a powerful negotiating tool. If issues are found, buyers can use the report to request repairs before settlement or negotiate a reduction in the purchase price.
What Should Be Included in the Report?
A good plumbing inspection should result in a written report that covers: the condition of all visible pipes and fixtures, water pressure readings, hot water system age and compliance, gas system compliance (if present at property), CCTV footage of drainage lines with commentary, and clear identification of any defects, risks, or items requiring further investigation.
If you’re getting quotes, ask specifically whether a written report and CCTV footage are included. Some cheaper inspections are verbal-only, which limits your ability to use the findings in negotiations or future planning.
How to Choose the Right Inspector
Look for a licensed plumber who specialises in pre-purchase or property inspections — not all plumbers offer this service. They should be licensed with the Queensland Building and Construction Commission (QBCC), able to include gas inspection if required, experienced with CCTV drain inspection, and willing to provide a detailed written report.
Avoid making your decision on price alone. A thorough inspection by an experienced inspector is worth paying a little more for, particularly when you’re making one of the biggest financial decisions of your life.
