Home insurance in Australia does not usually pay for mould on its own. It can pay for mould that follows a sudden insured event, such as a burst pipe, a storm or a flood your policy covers, because the insurer treats that mould as part of the water damage. Mould from condensation, slow leaks, rising damp or poor maintenance is almost always excluded, so the cause of the moisture decides the claim, not how bad the mould looks.
This is general information, not legal or financial advice. Your Product Disclosure Statement (PDS) and your insurer decide what your own policy covers.
How insurers decide: the cause, not the mould
Insurers look past the mould to the water event behind it.
| What caused the moisture | Usual treatment | Why |
|---|---|---|
| Burst pipe, failed flexi hose, appliance that suddenly overflowed | Often covered | Sudden, accidental escape of liquid; the mould is resulting damage |
| Storm damage letting rain in (lifted roof sheet, broken window) | Often covered if you hold storm cover | Storm is a standard insured event |
| Flood (rivers, creeks, lakes, dams) | Depends on your policy | Flood cover may be limited or excluded |
| Slow leak from a fitting, shower or roof over months | Usually excluded | Gradual damage or a maintenance matter |
| Condensation, poor ventilation, humidity | Usually excluded | A property condition, not an event |
| Rising damp or a failed damp-proof course | Usually excluded | Gradual and structural by nature |
| Mould that existed before the policy or the event | Excluded | Nothing sudden to claim against |
The line between “sudden” and “gradual” is where most disputes start. Policies typically exclude wear, tear and damage from a gradual process of leaking or dripping. In a case reported by Insurance News, the Australian Financial Complaints Authority (AFCA) rejected an insurer’s reliance on that exclusion for mould in a bedroom wardrobe caused by a leaking toilet supply pipe. AFCA said gradual damage of that kind usually develops over “months, if not years”, not “within a short space of time, such as days, weeks or even a month or two”, and required the insurer to accept the claim. One decision does not bind every case, but “gradual” is a factual question you can contest with evidence.
Storm and flood: check both words in your PDS
Storm cover is standard on most home policies. Moneysmart lists strong winds, rainwater run-off and rainwater overflowing from stormwater drains among what most policies cover. Flood is treated separately, under a standard definition: “the covering of normally dry land by water that has escaped or been released from the normal confines of” a lake, river, creek or other natural watercourse, reservoir, canal or dam. Moneysmart notes that where a home is at high risk of flooding, flood cover may be excluded.
In an Illawarra east-coast low, water through a storm-damaged roof is a storm claim; creek water across the floor is a flood claim, and only pays if you hold flood cover. The guide to mould after Illawarra storms covers the drying side of that risk.
Rising damp is almost never claimable, but check the diagnosis
Rising damp is ground moisture drawn up through masonry, usually through a failed or bridged damp-proof course. It is gradual by nature, so it and its mould are excluded. But staining labelled “rising damp” is sometimes a leaking pipe in a slab or a failed shower membrane behind the wall, and a pipe failure can be a sudden, claimable escape of water. Get the cause established with moisture readings before “rising damp” goes on a quote. The guide to rising damp versus condensation explains the patterns.
Contents insurance and mould
Contents cover can apply to furniture, carpets, mattresses and clothing damaged by mould after a covered water event, subject to your sums insured and any mould exclusion in the policy. Photograph every affected item, with labels or receipts where you have them, before anything is thrown out.
What to do after a water event if you may claim
Moneysmart’s claims guide says to review your policy, contact your insurer promptly, and photograph the damage before repairs. In order:
- Make it safe and stop the water. Turn off the supply for a plumbing leak; get a plumber or roofer to make the source safe.
- Photograph before you clean. The water source (the burst fitting, the damaged roof section), the wet materials, tide marks, then the mould, wide and close.
- Notify your insurer early, even if you are unsure you will claim.
- Talk to your insurer before spending on temporary repairs. Moneysmart advises this to avoid disputes, and many insurers have preferred repairers for emergency work.
- Start drying. A wet house left to sit grows more mould and starts to look like a maintenance problem on paper.
- Keep records. A dated log of when the event happened, when you found it, when you reported it and every step after; trade invoices; correspondence; weather records for storm events from the Bureau of Meteorology.
Describe the event accurately, starting with the trigger (“after the storm on [date] water came through the lounge ceiling”), and never overstate; if there was an earlier, unrelated repair, say so.
How a mould report supports a claim
A report that only says mould is present does little for a claim. A useful one links the mould to the event and covers:
- where the mould is and how far it extends
- moisture readings mapping the wet area back to its source
- an assessment of likely cause and timing
- a written scope of the remediation needed
That report is also your counter-evidence if the insurer’s assessor calls the damage gradual or condensation. A mould inspection and moisture assessment produces this, and for active water events the water damage and mould response covers drying with dated photos and moisture logs. Once work is done, a post-remediation verification documents that the area was returned to normal, which some insurers ask for before finalising.
Enquiries through this site are passed to an independent local remediation professional, who quotes and reports in their own name. Neither this site nor the contractor makes coverage decisions; your insurer does.
Timeframes the insurer must meet
According to Moneysmart, under the General Insurance Code of Practice an insurer should acknowledge your claim within 10 business days, update you at least every 20 business days, tell you within 5 business days if a loss assessor is appointed, and make a decision within 4 months of receiving the claim.
If your mould claim is refused
Common grounds are the gradual-deterioration exclusion, a “lack of maintenance” argument (the leak should have been noticed), a specific mould exclusion, or a finding that the mould pre-dated the event.
- Ask for the decision and the policy clause in writing. Compare the clause with what actually happened; insurers sometimes misapply their own wording.
- Make a formal complaint through the insurer’s internal complaints process. Moneysmart says the first step is always to contact the business and explain how you want it fixed. Attach your timeline, photos, plumber’s or roofer’s report and any independent mould report.
- Escalate to AFCA (afca.org.au) if the complaint is not resolved. AFCA is the external dispute scheme for insurance, and Moneysmart notes it hears complaints for free. It considers whether the exclusion actually fits the facts, which is where independent evidence on timing and cause carries weight.
- Get legal advice if the amount is large or the matter goes beyond AFCA.
If you own in a strata building, the owners corporation’s building policy usually responds to water entering through common property, while your own policy covers contents and your lot’s improvements. The strata mould guide covers who is responsible.
Frequently asked questions
Does home insurance cover mould damage in Australia?
Usually only when the mould results from a sudden insured event such as a burst pipe, storm damage or a flood you are covered for. Mould from condensation, slow leaks, rising damp or poor maintenance is generally excluded. Your PDS is the only reliable answer for your policy.
Can you claim mould damage on insurance after a burst pipe?
Often, yes. A burst pipe is typically treated as a sudden escape of water, and mould that develops as a direct result is commonly covered as part of that claim. Report it promptly and keep evidence of the failed fitting.
My insurer says the mould is from condensation, but I had a leak. What can I do?
Challenge the decision in writing with your evidence: photos, timeline, weather records and a plumber’s or roofer’s report. An independent mould report linking the moisture to the event is your strongest counter-evidence, and AFCA is the free external option if the insurer’s complaints process does not resolve it.
Does contents insurance cover mouldy furniture and carpets?
It can, if the mould follows a covered water event, subject to your sums insured and any mould exclusion. Photograph every item before disposal.
Can I choose my own mould remediation contractor for an insurance claim?
That depends on how the insurer settles the claim. Moneysmart explains that insurers may manage repairs through their own contractors, pay a cash settlement so you arrange the work yourself, or combine the two. Ask which applies before you commit to a contractor.
If you have had a water event and need the moisture source and extent documented, describe what happened and your suburb on the quote form and an independent local contractor can quote the inspection.
