Step 1: Report the loss immediately
Call your agent or your flood carrier's claims line as soon as it's safe — don't wait for cleanup. You'll get a claim number; write it down along with the adjuster's name when one is assigned. For NFIP policies, the formal Proof of Loss is generally due within 60 days of the loss, but extensions are routinely granted after major events. Private carriers set their own deadlines — check your policy's duties-after-loss section. Missing a deadline is the single most avoidable reason claims get denied.
Step 2: Prevent further damage (and keep receipts)
Your policy requires you to protect the property from additional harm: pump out water, cover broken windows, tarp the roof. This is called mitigation, and it's reimbursable — keep every receipt for pumps, tarps, emergency contractors, and temporary housing. What's not covered: permanent repairs made before the adjuster sees the damage. Mitigate, don't renovate.
Step 3: Document like a professional
The adjuster wasn't there. Your photos are the claim. For every damaged area: wide shots showing the room, close-ups of damage, waterlines with a tape measure visible, and serial/model numbers on appliances and systems. List every damaged item with approximate age and replacement cost — room by room. If you have pre-flood photos or video, they're worth real money now. Back everything up offsite.
Step 4: Meet the adjuster prepared
The adjuster inspects, measures waterlines, and builds a line-item estimate — usually in Xactimate, the industry's pricing software. Walk the property with them. Point out everything, including damage you think might be minor: wicking in drywall above the visible line, warped subflooring, compromised insulation. Ask questions. Get their direct contact info and a timeline for the estimate.
Step 5: Ask about advance payments
If you're displaced or facing major repairs, ask about an advance on your claim. NFIP insurers can issue advance payments (often up to $5,000–$20,000 depending on the event) before the final settlement. Private carriers have similar provisions. You don't get what you don't ask for — and early money is what keeps a contractor scheduled.
Step 6: Review the estimate line by line
When the estimate arrives, compare it against your own documentation and at least two contractor bids. Common gaps: missing line items for demo and debris removal, undermeasured square footage, omitted code-upgrade costs, and contents valued at actual cash value when you expected replacement cost. Flood policies pay building and contents under separate limits with separate deductibles — make sure both schedules are complete.
Step 7: If the offer is too low, push back
You have options, in this order: (1) submit a supplemental claim with your contractor's estimate and additional documentation — most underpayments are resolved here; (2) request a re-inspection or a different adjuster; (3) for NFIP claims, file a formal appeal with FEMA within 60 days of the denial or underpayment notice; (4) hire a licensed public adjuster (they take a percentage — typically 5–15% — so do the math); (5) as a last resort, consult an attorney who handles flood claims. Never sign a release or accept a "final" payment until you're satisfied the scope is complete.
What flood insurance doesn't cover
Know the exclusions before you're surprised: damage from earth movement (even if caused by flood), most basement contents beyond limited coverage, currency and precious metals, outdoor property like decks and landscaping, additional living expenses under a standard NFIP policy (private policies often add this — one more reason to compare), and damage you could have prevented after the loss. Mold is covered only if you made reasonable efforts to dry out promptly.
The timeline, honestly
A straightforward claim with good documentation: weeks. A major event with thousands of claims: months. Disputed or supplemented claims: longer. Your leverage at every stage is the same: thorough documentation, written communication, and persistence. Keep a claim diary — date, name, what was said — from the first call to the final check.
