Mould Complaint Letter to Your Landlord (Template)
A copy-paste mould complaint letter template for Australian renters. What to include, which standard to reference in your state, and the evidence that makes it work.
The difference between a mould complaint that gets fixed and one that gets ignored is rarely the adjectives. It’s the structure and the evidence. This template gives you both. One honest note before you copy it: we’re a research site, not lawyers. The template is a starting structure; your state’s tenancy authority (linked above) owns the actual process, and for anything contested, that’s the door.
The template
[Date]
To: [Landlord / property manager name] Re: Request for inspection and repair. Mould at [property address]
Dear [Name],
I am writing to formally report mould at the above property and to request inspection and repair.
What and where: Mould is present on [locations. E.g. the bedroom ceiling and the south wall of the living room]. I first noticed it on [date], and it has [stayed the same / spread. Describe factually].
Why it appears building-related: [e.g. It has returned after cleaning; it coincides with a leak / rising damp / a bathroom without a working extraction fan. State the facts you observe.]
Request: Please arrange an inspection and the repairs needed to address the underlying moisture cause within [a reasonable timeframe. Your state authority publishes repair timeframes]. Please confirm receipt of this letter and the intended next steps in writing.
[Where your state has minimum standards, add one factual sentence. E.g. Victoria: “For reference, Victoria’s rental minimum standards require each room to be free from mould and damp caused by, or related to, the building structure.” Queensland: “Queensland’s minimum housing standards require the premises to be free of damp and mould.”]
Evidence attached: [dated photos; prior messages; inspection or lab report if you have one].
Regards, [Name, contact details]
Why each block is there
- Written and dated. Formal repair processes in every state start with a written request; the date starts the clock.
- Facts, not fury. “returned after cleaning three times since May” outworks “disgusting mould everywhere” in every forum that matters.
- The building-related framing. Standards and repair duties generally attach to building-caused damp, not lifestyle-caused condensation; say plainly why yours looks structural. (Which standard applies where is in our state-by-state standards guide.)
- A timeframe and a paper trail. “please confirm in writing” turns silence into evidence too.
The evidence that does the heavy lifting
Dated photos beat descriptions; a pattern (“cleaned, returned, cleaned, returned”) beats a snapshot; and for disputed or serious cases, an independent inspection report with NATA-accredited lab analysis is the strongest single document a renter can attach. It answers the “is it really building-related?” question with a professional’s name on it. If it reaches the tribunal, that report is the exhibit everything else leans on.
If the letter doesn’t work
Don’t loop. Escalate through the formal path: repair request forms, the state authority’s process, then the tribunal (VCAT / NCAT / QCAT and equivalents). The tenants’ organisations linked above publish step-by-step guides for each stage, and they’re free.
Ready to act?
- Need the evidence first? An independent inspection report is the strongest attachment: what one should cost, or request quotes from vetted independents.
- Standards-change updates: the email signup lives on the mould decision path.
Common questions
What should a mould complaint letter to a landlord include?
Six things: the date and your address; a factual description of the mould and where it is; when you first noticed it and how it has progressed; why it appears building-related (leaks, rising damp, no working ventilation); a clear request for inspection and repair with a reasonable timeframe; and a list of the evidence you're attaching, like dated photos.
Should I mention minimum standards in the letter?
Where your state has them, yes. Factually, not aggressively. In Victoria, rooms must be free from mould and damp related to the building structure; in Queensland, minimum housing standards require premises free of damp and mould. Referencing the standard shows the request has a basis; your state tenancy authority confirms the exact wording.
What evidence should I attach?
Dated photos or video of the mould and any moisture source, a note of when it appeared and what you've already tried, any prior messages about it, and, for persistent or disputed cases, an independent inspection or lab report. Tribunals and authorities work on evidence; the letter is the cover sheet for it.
What if the landlord doesn't respond?
Every state has a formal repair-request pathway with timeframes, escalating to the tribunal (VCAT, NCAT, QCAT and equivalents). The tenancy authority or tenants' organisation in your state publishes the exact steps. Follow their process rather than improvising.
