Mould knowledge base
The questions owners, tenants and buyers ask most, answered against Australian health, building and tenancy guidance — including when a test isn’t worth paying for.
Do you need a mould test?
When a mould test is worth paying for in Queensland, when visible mould and damp already answer the question, and what testing can and can't tell you.
Bottom line: Pay for testing when it answers a question you can't answer by looking. Always pay attention to the moisture source.
ReadHow do you read a mould air test report?
What spore counts per cubic metre mean, why the outdoor sample is the yardstick, which spore types matter, and the red flags in a mould air test report.
Bottom line: Indoor versus outdoor, type by type. Read the sampling conditions before you read the numbers.
ReadWho is responsible for mould in a Queensland rental?
Queensland's minimum housing standard on damp and mould, who fixes what when mould appears in a rental, and how an inspection helps settle the cause.
Bottom line: Report mould early, in writing. Then let the evidence on cause — not the argument — decide who fixes it.
ReadWhat should you check for mould after a flood?
How mould develops after a flood or major leak, Queensland Health's safety advice, what stays wet inside walls, and when to test before rebuilding.
Bottom line: Dry first, measure second, close up last.
ReadIs your mould from condensation or a leak?
How to tell whether mould in a Queensland home comes from condensation or a leak: the patterns, the readings, and why it decides the fix and who pays.
Bottom line: Condensation is spread out and surface-deep. A leak is concentrated and goes into the material.
ReadCan mould in your home affect your health?
What Australian and WHO health guidance says about indoor mould, who is more likely to be affected, and what a mould inspection can and can't tell you.
Bottom line: Health questions belong with your GP. A mould inspection answers the building questions: where it's damp, why, and what's growing.
ReadShould you get a mould inspection before buying a house?
What a building and pest report may miss about mould, the warning signs at an open home, Queensland seller disclosure, and how to time a mould inspection.
Bottom line: Book it early in the inspection window, and tell the inspector anything the agent or neighbours mentioned about leaks or floods.
ReadAre DIY mould test kits worth it?
What DIY mould test kits and petri-dish settle plates can and can’t tell you, why they nearly always grow something, and better first steps.
Bottom line: Spend the kit money on a moisture meter or a humidity monitor, or on an inspection if the stakes are high.
