Scope and as-of date. This is a Florida analysis covering first-party water-damage claims under residential all-risk homeowners forms (HO-3 and HO-5). It addresses how carriers limit water losses by source (sudden-and-accidental discharge versus gradual seepage), how the standard "14 or more days" seepage exclusion has been construed, how mold sublimits and exclusions interact with ensuing-loss and anti-concurrent-cause provisions, how the burden of proof is allocated, and the statutory deadlines that now govern these claims after the 2021 and 2022 reforms. It states the law as of June 14, 2026, reflecting statutory amendments through the 2024 legislative session. It does not cover flood losses (which require NFIP or private flood coverage), commercial property forms, condominium association loss-assessment coverage under section 627.714, or the mechanics of statutory bad faith and civil remedy notices.
The short version: a sudden pipe burst is a covered direct physical loss under an all-risk form, but two carrier defenses recur. The first is duration, the policy's exclusion for seepage or leakage "over a period of 14 or more days" or "over a period of weeks, months or years." The second is causation, the argument that a gradual or excluded process (long-term seepage, wear and tear, faulty construction, or resulting mold) is the operative cause. Both defenses are governed by the all-risk burden-shifting rule and by Florida's concurrent-cause doctrine, and both turn heavily on the exact words the carrier used.
The coverage grant and who carries the burden
HO-3 and HO-5 forms insure the dwelling against direct physical loss except for what the policy excludes. That structure drives the burden allocation. Once the insured proves a direct physical loss to covered property during the policy period, the burden shifts to the insurer to prove the loss falls within an exclusion. The Second District stated the rule cleanly in Mejia v. Citizens Property Insurance Corp., 161 So. 3d 576, 578 (Fla. 2d DCA 2014): the insured carries the initial burden of proving a loss while the policy was in effect, and the burden then shifts to the insurer to prove the cause was excluded.
The practical consequence is that the insured does not have to prove the loss happened on a particular date, only that a covered physical loss occurred during the policy term. An insurer that wants to win on duration or source has to do the segregating itself.
The Fourth District turned this principle into an operative framework for multi-cause water claims in Jones v. Federated National Insurance Co., 235 So. 3d 936 (Fla. 4th DCA 2018), a hailstorm-versus-wear-and-tear roof case reversed for an erroneous jury instruction. Read together with Mejia and the concurrent-cause cases below, Jones lays out the sequence a fact-finder should follow:
- The insured must show the damage occurred while the property had coverage. If not, judgment for the insurer.
- If that burden is met, the insurer must establish either a sole cause or, where there is more than one cause, an efficient proximate cause of the loss.
- If the insurer proves a sole or efficient proximate cause, it must then prove that cause is excluded. If it proves the cause but not the exclusion, judgment for the insured.
- If the insurer cannot establish a sole or efficient proximate cause and no anti-concurrent-cause provision applies, the concurrent-cause doctrine controls, and the insurer bears the initial burden of producing evidence that an excluded risk contributed.
- If the insurer produces that evidence, the insured must produce evidence that a covered risk was a concurrent cause.
- If the insured does, the insurer must prove the purported covered cause was not in fact a concurrent cause or was itself excluded.
Jones, 235 So. 3d at 941 to 942. This is the spine of nearly every contested water-damage trial in Florida, and it explains why carriers fight so hard at step two: if no efficient proximate cause can be isolated, the insured usually reaches the jury.
Concurrent causation: Sebo and the role of anti-concurrent-cause language
When a covered peril and an excluded peril combine, Florida applies the concurrent-cause doctrine, not the efficient-proximate-cause doctrine, where the perils are independent and no single one can be called the sole or efficient cause. The Florida Supreme Court settled this in Sebo v. American Home Assurance Co., 208 So. 3d 694 (Fla. 2016), quashing the Second District and approving the Third District's reasoning in Wallach v. Rosenberg, 527 So. 2d 1386 (Fla. 3d DCA 1988). In Sebo, rainwater and Hurricane Wilma combined with defective construction to destroy an $8 million home; because the causes acted in concert and no efficient cause could be isolated, coverage existed under the all-risk policy even though defective construction was excluded. Sebo, 208 So. 3d at 700.
Sebo is controlling, and it carries the caveat that decides most of these cases. The Court noted that the carrier had written anti-concurrent-cause language into other parts of the Sebo policy but not into the relevant exclusion, and held that because the insurer did not contract around the concurrent-cause doctrine for that exclusion, the doctrine applied. Id. at 700. The lesson for both sides is that an anti-concurrent-cause clause, the "we do not insure for loss caused directly or indirectly, regardless of any other cause or event contributing concurrently or in any sequence" lead-in, can defeat concurrent-cause coverage when it is actually attached to the exclusion the carrier invokes. One limit worth noting: the Sebo policy was a manuscript form written for that specific residence, and commentators have questioned how directly its reasoning carries to standard HO-3 and HO-5 forms. The drafting principle it establishes, that anti-concurrent-cause language must sit in front of the exclusion the carrier relies on, does not depend on that distinction.
Two decisions show the clause working as drafted. In Liberty Mutual Fire Insurance Co. v. Martinez, 157 So. 3d 486 (Fla. 5th DCA 2015), subsurface water pressure forced a drained pool out of the ground and damaged the deck and surrounding features. The Fifth District reversed summary judgment for the insureds and directed judgment for Liberty Mutual: the water-damage exclusion carried anti-concurrent-cause language, the loss resulted directly or indirectly from the excluded subsurface water, and the policy's ensuing-loss exception did not rescue coverage because the ensuing damage was directly related to the excluded risk. The court's footnote is the cleanest Florida statement that parties may contract around the concurrent-cause doctrine with an anti-concurrent-cause provision. Martinez, 157 So. 3d at 487 n.1.
Jones sharpens the point by showing it operates exclusion by exclusion. There, only three of the five invoked exclusions contained anti-concurrent-cause language, so the trial court could not apply the efficient-proximate-cause framework uniformly across all of them. The drafting question is therefore not whether the policy contains an anti-concurrent-cause clause somewhere, but whether it sits in front of the specific exclusion the carrier is relying on.
This is also where mold enters. Florida permits clearly written mold sublimits and "fungi, wet or dry rot, or bacteria" exclusions. As a practice observation rather than a matter of settled appellate holding, a clearly drafted sublimit is generally enforced on its terms, and the contested question is rarely the validity of a clear mold limit; it is causation and sequence. If mold ensues from a sudden covered discharge, the ensuing-loss analysis and the concurrent-cause framework above decide how far coverage reaches and where the sublimit caps it. If the carrier proves the mold grew out of long-term seepage that the policy excludes, and the relevant exclusion carries anti-concurrent-cause language, Martinez shows the exclusion can reach the entire chain. We are aware of no controlling Florida Supreme Court decision treating a clearly worded mold sublimit as ambiguous, and, again as a practice observation, insureds who frame the fight as a pure ambiguity challenge to a clear sublimit tend to lose. The productive challenge attacks causation and the ensuing-loss line, not the number printed in the declarations.
The 14-day seepage clause: Hicks, Whitely, and the wording that decides it
The most-litigated duration limit excludes loss "caused by constant or repeated seepage or leakage of water over a period of 14 or more days." Carriers long read it to bar the entire loss whenever water had been escaping for more than two weeks. The Fifth District rejected that reading.
In Hicks v. American Integrity Insurance Co. of Florida, 241 So. 3d 925 (Fla. 5th DCA 2018), a refrigerator supply line leaked for roughly five weeks while the insured was away, discharging close to 1,000 gallons a day by the time he returned. Reviewing competing summary judgment motions, the court held that a policy excluding losses "caused by" seepage "over a period of fourteen days or more" does not unambiguously exclude losses caused by seepage over a period of thirteen days or less. Hicks, 241 So. 3d at 927. It reversed summary judgment for the carrier and remanded with directions to enter partial summary judgment for the insured on coverage for the first thirteen days, leaving the extent of those losses for trial and placing on the insurer the burden of proving which damage occurred after day thirteen. Id. at 928. The opinion is per curiam and published, and rehearing was denied.
The same panel court followed Hicks months later in Whitely v. American Integrity Insurance Co. of Florida, 249 So. 3d 1312 (Fla. 5th DCA 2018). A bathroom water release exposed a vacation home to water for about thirty days by the carrier's expert's estimate. The court reversed summary judgment for the insurer and held that the undisputed fact of more than fourteen days of exposure did not establish that the loss itself occurred on or after the fourteenth day. The carrier, not the insured, had to make that showing, and whether it could was a genuine issue of material fact. Notably, the Whitely panel rejected the insureds' separate ambiguity attack on the "caused by leakage of water" language, so the ambiguity it recognized is specifically temporal.
Then comes the limit that every adjuster and coverage lawyer needs to internalize. The thirteen-day carve-out is a product of the words "14 or more days." Where the policy instead excludes seepage "which occurs over a period of weeks, months or years," there is no fourteen-day trigger and no first-thirteen-days argument. The Fourth District drew exactly that line in Feldman v. Citizens Property Insurance Corp., No. 4D22-865 (Fla. 4th DCA Aug. 30, 2023) (published; opinion). After a living-room ceiling collapsed, Citizens denied the claim under a "weeks, months or years" seepage exclusion that also carried anti-concurrent-cause language. The court reversed in part, holding the insured was entitled to a directed verdict on his initial burden because he proved a physical loss during the policy period, and remanded for trial on the exclusion. But it affirmed the trial court's refusal to give the insured's proposed "first 13 days" instruction, because the policy contained no "fourteen days or more" language and Hicks was therefore factually distinguishable.
The settled-versus-open line matters here. The thirteen-day rule for the "14 or more days" wording is established Fifth District authority and is undisturbed by Feldman, which addressed only the different "weeks, months or years" wording. The Florida Supreme Court has not addressed the fourteen-day clause, and no district has squarely rejected the Hicks construction for an identically worded clause. So in a Fifth District venue the carve-out is the rule; elsewhere it is persuasive but not yet adopted on point, and the carrier's chosen wording may take the argument off the table entirely. Venue and policy language, not a single statewide answer, decide the case.
Late discovery, post-loss duties, and the presumption of prejudice
Gradual leaks surface late, which hands carriers a second front: the insured's post-loss obligations. Prompt notice, a sworn proof of loss, document production, an examination under oath, and preservation of the loss site for inspection are conditions, and a material breach can forfeit coverage. The Third District's rule is that once the insurer pleads and proves a material breach of a post-loss obligation, prejudice to the insurer is presumed, and the burden shifts to the insured to prove the breach did not prejudice the carrier. American Integrity Insurance Co. v. Estrada, 276 So. 3d 905, 912, 916 (Fla. 3d DCA 2019).
That rule is current and being enforced. In Universal Property & Casualty Insurance Co. v. Alvarez, No. 3D24-1853 (Fla. 3d DCA May 13, 2026) (opinion), the Third District reversed a $20,000 plaintiff's verdict and ordered a new trial because the trial court told the jury the presumption of prejudice applied only to the prompt-notice defense and not to the insured's failure to provide a sworn proof of loss, produce requested documents, or preserve the roof for inspection before repairs. Quoting and applying Estrada, the court held the presumption applies to all post-loss obligation defenses, not just notice. The decision was not final pending any timely rehearing motion when issued, so confirm its status before relying on it, but it reflects the prevailing Third District approach.
For a gradual-leak claim this means the carrier often has parallel theories: the duration exclusion limits the loss, and a post-loss breach (late notice once water damage finally became visible, repairs made before inspection, an incomplete proof of loss) shifts the prejudice burden to the insured. Insureds counter the duration theory by dating the loss with forensic evidence and counter the post-loss theory by documenting that the carrier had a full and fair opportunity to investigate.
The deadlines that now govern these claims
The 2021 reform (Senate Bill 76, chapter 2021-77) and the December 2022 special-session reform (Senate Bill 2-A, chapter 2022-271) compressed the timeline on both sides. As of June 14, 2026 the operative deadlines for a residential property claim are:
- Acknowledge claim communications: within 7 calendar days of receipt (reduced from 14). Section 627.70131(1)(a), Florida Statutes.
- Begin investigation: within 7 days after the insurer receives the proof-of-loss statements. Section 627.70131(3)(a).
- Physical inspection (hurricane claims): within 30 days (reduced from 45). Section 627.70131(3)(b).
- Pay or deny the claim, in whole or part: within 60 days after notice of an initial, reopened, or supplemental claim (reduced from 90), absent factors beyond the insurer's control, with interest accruing from the date the claim was filed. Section 627.70131(7)(a). Effective March 1, 2023.
- Insured's notice of a new or reopened claim: within 1 year after the date of loss, for policies issued on or after December 16, 2022; policies issued earlier remain governed by Senate Bill 76's 2-year period. Section 627.70132(2), Florida Statutes.
- Insured's notice of a supplemental claim: within 18 months after the date of loss, again for policies issued on or after December 16, 2022; the prior 3-year period controls for earlier-issued policies. Section 627.70132(2).
- Date of loss for weather events: the date the hurricane made landfall or the date the windstorm, severe rain, or other weather event is verified by NOAA. Section 627.70132(3). For non-weather water losses, such as a pipe burst, the date of loss is the date of the loss event itself.
- Presuit notice of intent to litigate: a condition precedent to suit, filed with the Department of Financial Services on the department's form, served at least 10 business days before filing suit and not before the insurer's coverage determination under section 627.70131; the insurer must respond in writing within 10 business days. Section 627.70152, Florida Statutes.
- Suit limitation: 5 years for breach of a property insurance contract, running from the date of loss. Section 95.11, Florida Statutes (date-of-loss trigger traced to Senate Bill 408 (2011), now codified at section 95.11(2)(e)).
The claim-notice contraction is the change most likely to ambush a gradual-leak file. Under Section 627.70132, a hidden leak that the homeowner does not discover for more than a year can be time-barred on notice before anyone reaches the merits of the seepage exclusion, because the statute runs from the date of loss, not the date of discovery. Senate Bill 76 had set this period at 2 years for new and reopened claims and 3 years for supplemental claims; Senate Bill 2-A cut those to 1 year and 18 months. That is a meaningful narrowing for exactly the slow-onset water losses this article addresses.
Two related reforms change the litigation calculus even though they are not coverage rules. Senate Bill 2-A eliminated the one-way attorney-fee entitlement that had driven first-party property litigation (the former application of sections 627.428 and 626.9373 to these suits) and prohibited the assignment of post-loss benefits under residential property policies issued on or after January 1, 2023. It also authorized mandatory binding arbitration endorsements under section 627.70154. These do not change whether a seepage loss is covered, but they change how, and how often, the coverage question gets litigated. How far these reforms reach a given file is itself contested: under chapter 2023-172, the fee repeal and the assignment ban apply by the policy's issuance or renewal date, and courts continue to work out retroactivity for claims and suits that straddle the 2021 through 2024 changes.
What this means by role
Coverage counsel. Plead the exclusion as an affirmative defense and be ready to carry it. In a Fifth District venue with "14 or more days" wording, Hicks and Whitely put the burden on the carrier to segregate post-day-thirteen damage, so build the forensic dating proof early or expect the first-thirteen-days exposure to go to the insured. Check whether the anti-concurrent-cause lead-in actually precedes the exclusion you are invoking, because Sebo and Jones make that placement dispositive on whether concurrent-cause coverage survives. For policyholder counsel, establish the in-period loss to force the burden across under Mejia and Jones, attack any instruction that applies efficient proximate cause without first asking whether an efficient cause can be identified, and press the first-thirteen-days theory where the wording supports it.
Underwriting and forms. Wording choice is doing real work. The "weeks, months or years" formulation avoided the Hicks carve-out in Feldman, while the "14 or more days" formulation invited it. If the intent is to bar slow-leak losses outright, the drafting and the Feldman and Hicks contrast should inform which clause goes on the form. Attach anti-concurrent-cause language to each water-related exclusion you intend to rely on, not just to a general lead-in, given how Sebo penalized the carrier for inconsistent drafting and how Jones applied the analysis exclusion by exclusion. State mold sublimits unambiguously, and weigh an arbitration endorsement under section 627.70154. On rate filings, the shortened notice window, the fee repeal, and the assignment ban all bear on assumed loss-adjustment expense and litigation frequency for water and mold exposures.
Claims and reserving. Distinguish how long water was present from when the loss occurred. Whitely holds that "the property was wet for thirty days" does not, by itself, prove the loss happened on or after day fourteen, so an adjuster who denies a "14 or more days" claim outright, without dating the damage, is handing the insured the first-thirteen-days argument. Preserve post-loss-duty defenses correctly: under Estrada and Alvarez, a proven material breach (a missing sworn proof of loss, repairs before inspection, an incomplete document response) shifts the prejudice burden to the insured, but only if it is pleaded and established. Reserve for first-thirteen-days exposure in Fifth District venues, mind the 60-day pay-or-deny clock and the 7-day acknowledgment, and calendar the insured's one-year notice deadline because a late-discovered leak can resolve on Section 627.70132 before the seepage exclusion is ever reached.
