The cause matters, not the discovery.
Across the country, homeowners are learning a hard lesson about the language of loss: discovering damage and causing it are not the same thing in the eyes of an insurer. The industry draws a firm line between sudden harm and harm that accumulates quietly over time, and that line — often set at seventy-two hours — can mean the difference between a full payout and a bill the homeowner must carry alone. As disputes over gradual damage rise steadily through the ombudsman's office, a deeper question surfaces about what insurance is truly understood to promise, and what it is actually designed to deliver.
- A man fell through his own bathroom floor and walked away with a claim capped at a fraction of the repair cost — not because the damage wasn't real, but because it wasn't sudden enough.
- Insurers are drawing a hard line at seventy-two hours: anything that develops beyond that window is classified as gradual, and gradual damage is either capped or denied outright.
- Gradual damage disputes now account for six percent of ombudsman cases — up from five percent the year prior — and the ombudsman has flagged it as a top-five issue for two years running.
- Homeowners who discover damage suddenly are finding that discovery and causation are treated as entirely separate events, leaving them exposed to costs their policies were never designed to absorb.
- The path to a successful dispute is narrow: expert reports from engineers or water damage specialists are increasingly the only evidence capable of shifting an insurer's interpretation of when and how damage began.
One morning, a man stepped out of his shower and fell through the bathroom floor. Beneath the tiles lay extensive water damage — rotting substrate, pooling moisture, unmistakable deterioration. He filed a claim. His insurer acknowledged the leak was real but ruled the damage gradual rather than sudden, capping his payout at between two and five thousand dollars. He took his case to the Insurance and Financial Services Ombudsman, arguing that MDF breaks down rapidly once wet and the damage must have been swift. The ombudsman disagreed. The evidence — hidden leaks, mould — pointed to weeks or months of development. The cap held.
In a separate case, a couple filed a claim after a storm left cracks in their walls, fallen tiles, and a widening gap near their benchtop. Their insurer rejected the claim and cancelled their policy, citing a builder's report they had failed to disclose. Investigators found the damage traced to long-term ground movement, faulty construction, and wear — not the storm. The weather had exposed the problem, not created it.
The ombudsman, Karen Stevens, describes a widening gap between what homeowners expect and what their policies actually cover. Most people assume that discovering damage means their insurer will pay to fix it. But insurance covers sudden damage — not damage that develops over time, even when that development goes unseen. The cause is what matters, not the moment of discovery.
Hidden water damage almost always falls on the wrong side of that line. Internal guttering concealed inside walls can harbour problems for months before anything becomes visible. Mould and persistent minor leaks are treated as evidence of gradual harm. And leaving a leak unresolved compounds the exposure — any additional damage that results is unlikely to be covered at all.
For those caught in a dispute, Stevens recommends engaging a qualified expert — an engineer or water damage specialist — to provide evidence on causation and timing. Without it, homeowners are left arguing against their insurer's interpretation with little more than their own account. A capped claim may cover only a fraction of repair costs. A denied claim leaves them to pay everything themselves.
A man stepped out of his shower one morning and the bathroom floor gave way beneath him. When he looked underneath, he found the culprit: water damage, extensive and unmistakable, pooling beneath tiles and rotting the substrate. He filed an insurance claim expecting to be made whole. The insurer acknowledged the leak was real. But it refused to pay the full amount. The damage, they said, had not happened suddenly. It had developed over time. So his claim was capped—reduced to somewhere between two and five thousand dollars, the standard limit most policies allow for what the industry calls gradual damage.
This man is not alone. Across the country, homeowners are discovering that the moment they discover damage and the moment damage actually occurred are two entirely different things in the eyes of their insurers. The distinction is not semantic. It is the difference between a covered claim and a capped one, between repair and financial ruin.
The man argued his case to the Insurance and Financial Services Ombudsman. He pointed out that MDF—the engineered wood used in most bathroom floors—breaks down quickly once water reaches it. The damage must have been sudden, he reasoned. The ombudsman disagreed. To qualify for full coverage, the scheme ruled, damage had to occur instantly, all at once. The evidence showed a hidden leak and mould that would have taken weeks or months to develop. The insurer had applied its policy correctly. The claim remained capped.
In another case, a couple discovered cracks running through their walls, tiles that had fallen away, and a visible gap opening between their benchtop and the wall. A storm had just passed through. They filed a claim. The insurer rejected it entirely, arguing the damage was not sudden. Then it went further: the company cancelled their policy altogether, citing their failure to disclose pre-existing issues that had appeared in a builder's report years earlier. When the couple complained to the ombudsman, investigators found that the damage stemmed from long-term ground movement, wear and tear, faulty construction, or earth shift—not from the storm. The weather event may have exposed the problems, the scheme concluded, but it did not cause them.
The pattern is hardening into a trend. This financial year, six percent of disputes the ombudsman accepted for investigation involved gradual damage claims—up from five percent the year before. Karen Stevens, the ombudsman, called it one of the top five issues her office has tracked for two consecutive years. The gap, she explained, lies between what people reasonably expect and what policies actually cover. Most homeowners assume that if they discover damage in their house, their insurer will pay to fix it. Insurance, however, covers only sudden damage. It does not cover damage that develops over time, even if that damage is discovered suddenly. The cause matters, not the discovery.
Insurers typically treat anything that occurs outside a seventy-two-hour window as gradual. Hidden water damage almost always qualifies. Internal guttering—the kind tucked inside walls—can conceal problems for months or years before serious deterioration becomes visible. Mould and small persistent leaks are red flags that point to gradual damage. Leaving a leak unresolved does not just worsen the immediate problem; it creates additional damage that almost certainly will not be covered at all.
For homeowners facing a disputed claim, the path forward is narrow and expensive. Stevens recommended engaging an expert—an engineer, a water damage specialist, someone with credentials—to provide evidence about what caused the damage and when. Expert reports, she said, can be critical in resolving disputes, especially when the question of causation and timing is contested. Without that evidence, homeowners often find themselves arguing against the insurer's interpretation with nothing but their own observations and frustration. The financial stakes are real. A capped claim might cover a fraction of actual repair costs. A denied claim leaves the homeowner to pay everything themselves.

Insurance only covers sudden damage, not damage that occurs over time and may have been discovered suddenly. It is the cause of the damage, rather than its discovery, that has to be sudden.— Karen Stevens, Insurance and Financial Services Ombudsman
The Hearth Conversation Another angle on the story
Why does it matter so much whether damage happened suddenly or gradually? Isn't the damage the same either way?
The damage is identical, yes. But insurance is built on the idea of covering unexpected events—sudden loss. Gradual damage is seen as something you should have caught and fixed along the way. It's a preventable problem, in their logic.
But in the bathroom floor case, the leak was hidden. How could the homeowner have caught it?
That's exactly the tension. The insurer says the damage developed over time, so it's gradual. The homeowner says the floor collapsed suddenly. Both things are true, but insurance only cares about the cause, not the discovery.
So a homeowner could find catastrophic damage and still be capped at five thousand dollars?
Yes. And if the insurer decides it wasn't sudden enough, the cap applies. Most policies treat anything outside seventy-two hours as gradual. A slow leak over weeks or months—even if you only just found it—gets capped.
What's the ombudsman's role in all this?
They investigate disputes, but they're interpreting the same policies the insurers wrote. In most cases, they've sided with the insurers. The ombudsman's main advice now is: get an expert report. Prove causation. But that costs money most people don't have.
Is this getting worse?
The ombudsman says gradual damage disputes have risen to six percent of their caseload. It's becoming one of their top five issues. More people are discovering damage and finding their claims capped or denied.
