Landlord, agent or property manager? We do the same work for you: an assessment that settles what’s causing the mould and what needs fixing, before a complaint becomes a hearing. Since 1988. Same number: 1300 888 338.
Who is responsible for mould in a rental?
Mould is a frequent source of dispute between tenants and landlords. In NSW, rental homes must meet minimum standards, including adequate ventilation. If a mould issue arises because of a breach of these standards, or because the landlord fails to make a timely repair, then the landlord is responsible. If the mould develops during the tenancy as a result of the tenant’s actions, the tenant may be responsible for fixing it. (Source: Safety in the home | NSW Government)
The trouble is that in a real dispute, each side has a theory and neither has evidence. The landlord says the tenant never opens a window. The tenant says the roof leaks. Until someone works out where the moisture is actually coming from, the argument can run for months while the mould keeps growing.
What an inspection changes
At Airsafe, we don’t get involved in the blame game between landlords and tenants. What we do is establish the facts. An inspection finds the source of the moisture, not just the visible growth – and the source is usually what decides the argument. A leaking pipe or a failed damp course points one way. Condensation in a bathroom where the fan never gets switched on points another.
Philip Turner attends and reports on tenant-side inspections personally. Certified Occupational Hygienist is a professional certification awarded by the Australian Institute of Occupational Hygienists, and it matters here for a practical reason: tribunals and courts pay attention to the qualifications of the person who signed the report.
What you get
A Mould Inspection Report that sets out where the mould is, where the moisture is coming from, what the laboratory found, and a scope of works a remediation contractor can quote from – with photographs throughout, so you can see what we saw. Laboratory analysis is carried out by a separately NATA accredited laboratory.
Often, putting the facts on the table is enough to get the problem fixed without a hearing. And once remediation is done, we can come back and verify it with a clearance inspection, so everyone knows the problem is actually fixed.
For landlords, agents and property managers
A report like this protects you too. If a tenant reports mould, an assessment settles whether the building is the problem – and if it is, exactly what to fix, so you’re not paying for remediation that misses the source and doing it all again next winter. If the building isn’t the problem, the report says that too. Because we don’t sell the remediation, our report reads the same whoever engages us.
We work for landlords, agents, strata managers and property managers across Sydney and NSW, on single apartments through to whole buildings.
How quickly can we get there?
We can normally have an occupational hygienist on site the next day. Just call 1300 888 338 and we’ll tell you when we can be there. For our full inspection and clearance process, see our mould testing and inspections page.

FAQs
-
Yes. Tenants engage us directly. Philip Turner attends and reports, and the report is yours to use – with the agent, at NCAT, or in court.
-
The report establishes what the mould is, where the moisture is coming from, and what needs to be done. Responsibility is a matter for the tenancy laws and, if it gets that far, for NCAT – not for us. But cause and responsibility usually travel together: a report showing a roof leak, rising damp, or condensation from inadequate ventilation tends to make the responsibility question a much shorter one.
-
No, it’s not a requirement. But NCAT decides on evidence, and photographs on a phone only go so far. A report from a Certified Occupational Hygienist documents the mould, the moisture source and the laboratory results in a form the tribunal can rely on.
-
A company that sells the remediation has an interest in the answer. It’s not that we believe they’d deliberately get it wrong, but a lack of independence can subtly influence the way results are interpreted. We don’t do mould removal, so there’s no conflict of interest in our report.
