A building and pest inspection doesn’t always catch mould – especially mould that’s hidden behind walls, under flooring, or inside a subfloor that a standard inspector won’t crawl into with air-sampling equipment. For a purchase this size, that’s a significant blind spot.
Why a Standard Building Inspection Isn't Enough
Building and pest inspectors are trained to identify structural defects and pest damage, not to test air or surfaces for mould contamination. If a property has a musty smell, water staining, or a history of flooding or leaks, a dedicated mould inspection fills that gap with actual testing – not just a visual guess.
What's Included in a Pre-Purchase Mould Inspection
- Visual survey of high-risk areas (bathrooms, subfloor, roof cavity, window frames)
- Moisture mapping and thermal imaging to detect hidden water damage
- Surface swabs and/or air sampling where contamination is suspected
- A written report suitable for use in price negotiations or as a condition of sale
Timing: When to Book
Ideally, a pre-purchase mould inspection is scheduled alongside your standard building and pest inspection, within your contract’s due diligence period – so results are back before your cooling-off period or finance clause expires.
What If Mould Is Found?
A positive result doesn’t necessarily mean walking away from the deal. It gives you leverage – a documented scope of works you can use to negotiate price, request remediation before settlement, or make an informed decision about ongoing costs.
For Sellers: Getting Ahead of the Problem
If you suspect a mould issue in a property you’re about to list, a pre-listing inspection lets you address it before a buyer’s inspection surfaces it during negotiations – often cheaper and less stressful than dealing with it under contract pressure.
