The single most common thing we hear from someone whose claim closed a year ago is that they assumed the number was final. It usually was not. It was the number the carrier could support from a single inspection, and inspections miss things.

Florida has a defined route for that: the supplemental claim. It is not an appeal, it is not a complaint, and it is not the same thing as a reopened claim.

Supplement, reopen, appeal: three different things

Florida’s notice statute defines the first two precisely, and the difference changes your deadline.

Supplemental claim. A claim for additional loss or damage from the same peril which the insurer has previously adjusted, or for costs incurred during repairs under an open claim. Notice is due within 18 months after the date of loss.
Reopened claim. A previously closed claim reopened at the insured’s request for additional costs for loss or damage previously disclosed to the insurer. This runs on the same one-year clock as an original claim.
Dispute over what was already adjusted. Not a supplement at all. That is appraisal, mediation or suit, and the routes are different.

The distinction is worth pausing on: new damage from the same peril gets 18 months, while more money for damage the carrier already knew about gets 12. If your situation could be described either way, treat the shorter clock as the one that applies until someone tells you otherwise.

What legitimately supports a supplement

Damage found during repairs, which is the classic case: opening a wall or a roof deck reveals rot, saturation or structural damage nobody could see.
Costs that exceeded the estimate because the estimate priced work that could not actually be done that way.
Code-required work triggered once the permit was pulled.
Matching problems: a discontinued tile or flooring that turns a repair into a replacement.
Contents damage found after the fact, particularly in stored or enclosed spaces.
Consequential damage that developed from the original loss, such as mold following an unremediated water intrusion.

What does not support a supplement is a change of mind about a number that was correctly scoped the first time. The claim is that something was missed, and the evidence has to show it was.

How to build one that gets paid

Supplements fail on documentation far more often than on merit. The package that works has four parts:

Proof of the new damage. Photographs at the moment of discovery, dated, with enough context to show where in the property it is.
A causal link to the original peril. The carrier’s first question is whether this is new damage from a new event. Answer it before it is asked.
A line-item scope. Priced the same way as the original estimate so the two can be read side by side. A lump sum invites a lump-sum rejection.
The paper trail. Contractor findings, invoices, permits, moisture readings, lab results where mold is involved.

Once notice of a supplemental claim is given, the carrier’s clocks apply: Florida requires the insurer to pay or deny an initial, reopened or supplemental property insurance claim, or a portion of it, within 60 days after receiving notice of it, subject to factors beyond the insurer’s control as defined in the statute.

The fee rule that protects you

Supplements attract bad actors, so Florida wrote a specific rule. Where a public adjuster contracts with you to reopen a claim or file a supplemental claim on a claim already paid in part or in full or settled, the adjuster may not charge, agree to or accept compensation based on a previous settlement or previous claim payments by the insurer for the same cause of loss. Compensation must be based only on the claim payments or settlements obtained through the adjuster’s work after the contract was signed, and may not exceed 20 percent of the reopened or supplemental claim payment, still subject to the overall statutory caps.

If someone proposes taking a percentage of what you were already paid, that is the provision to point at. Full detail on fees is in what a public adjuster costs.

If the deadline has already passed

It is still worth a call, for two reasons. First, the current 12-month and 18-month windows came in with Florida’s December 2022 special session and losses before that change may fall under the earlier, longer periods. Second, the lawsuit clock is separate: an action for breach of a property insurance contract must be brought within five years, running from the date of loss, and a claim that can no longer be supplemented may still be actionable.

What we will not do is tell you a deadline is fine when we have not checked which version of the statute applies to your date of loss. Bring the date and the paperwork and we will work out where you actually stand.

Where we see supplements most

The Gulf coast produces the highest volume of genuine supplements, because storm surge and wind damage keep revealing themselves during repair. We handle a steady stream in Sarasota, Venice and North Port, where post-Ian repairs are still turning up damage nobody scoped in the first pass.

If your repairs found something the estimate never mentioned, do not absorb it. Send us the original estimate, the payment history and photographs of what was found. See water damage claims and mold claims for the two perils that most often surface late.

Your policy is the contract, and forms vary by carrier. The provisions described here come from the standard Homeowners 3 Special Form that most Florida homeowners policies are built on. Read your own declarations page and policy form, or send them to us and we will read them with you.
