Property Insurance Claims
California Water Damage Claims
Water damage is the most common homeowner claim — and the most commonly denied. The fight almost always comes down to one thing: whether the loss was sudden and covered, or gradual and excluded. Insurers know it, and they routinely recast a covered burst pipe as long-term seepage to avoid paying. We prove the true cause of loss and hold your carrier to the full cost of repair.
What We Handle
Common Causes & Scenarios
Sudden vs. Gradual
Most policies cover sudden, accidental water damage but exclude long-term seepage. This is where these claims live or die, and carriers routinely mislabel a covered burst as excluded 'gradual' damage. We bring in cause-and-origin experts to prove what actually happened.
Flood Is Different
Standard policies exclude flood — surface and rising water — which needs separate coverage. Insurers sometimes wrongly call a covered plumbing loss a 'flood' to deny it. Framing the claim correctly from the start matters.
Mold Sublimits
Even when the water is covered, resulting mold is often capped at a low sublimit, so carriers push to characterize damage as mold. The covered water loss itself should still be paid in full.
Anti-Concurrent-Causation Clauses
If an excluded cause combines with a covered one, insurers may argue the entire loss is excluded. These clauses are a common denial tool — and they don't always apply the way the carrier claims.
Slab Leaks
Leaks beneath the foundation are expensive and hard to detect, and insurers frequently dispute both cause and scope. We document the loss and pursue the full cost of repair, not just a patch.
Underpaid & Delayed Claims
Carriers commonly accept a water loss but pay far less than the true repair cost, or drag the claim out. We value it independently and, when a carrier acts unreasonably, pursue bad-faith damages.

No Upfront Cost
We handle water-damage claims on contingency. You pay nothing out of pocket, and our fee is a percentage of what we recover. If we don't recover, you owe no attorney fee.
We Prove the Cause
The whole case turns on cause and timing. We retain plumbers and cause-and-origin experts to establish that a loss was sudden and covered — the evidence that beats a 'gradual' denial.
Full Repair Value
We don't accept the carrier's first number. We value the full scope of repair — including the mold and drywall work insurers like to sublimit away — and fight for all of it.
Attorney-Led Representation
Counsel is assigned to every case, even in pre-litigation.
Selective Case Acceptance
We accept fewer matters to maintain focus and precision.
Strategy Over Volume
Decisions are deliberate, not automated.

Frequently Asked Questions
My insurer says my water damage was 'gradual.' Can I challenge that?
Yes. Whether damage was sudden or gradual is a factual question, and insurers often get it wrong. A plumber or cause-and-origin expert can establish that a pipe failed suddenly, which is typically covered. That evidence is the key to reversing a 'gradual' denial, and an unreasonable denial can support a bad-faith claim.
Does homeowner insurance cover flood damage?
No. Standard homeowner policies exclude flood — surface and rising water — which requires separate coverage through the NFIP or a private flood policy. But a covered plumbing loss is different from flood, and carriers sometimes wrongly label one as the other to deny a claim.
Why did my insurer only pay a small amount for mold?
Many policies cap mold remediation at a low sublimit even when the underlying water loss is fully covered. Insurers may push to characterize damage as mold to trigger that cap. The characterization can be challenged, and the covered water damage should be paid in full.
How long do I have to sue my insurer on a water claim?
Most property policies require suit within 12 months of the loss under Insurance Code section 2071. The clock is generally tolled while your claim is being handled, but the deadline is easy to miss, so have it checked as soon as you're in a dispute.
