Phase 01 · Workflow

Claim roadmap

Follow the CMS-verified steps in order and keep a written record as you progress.

1
Document char, soot, and odor damage room-by-room before any cleaning contractor starts.
2
File FNOL and ask whether the carrier authorizes emergency board-up and dry cleaning.
3
Obtain a scope from a fire restoration contractor—not just a general handyman estimate.
4
When the adjuster scope is lower, request a line-by-line supplement citing code upgrade needs.
5
Track recoverable depreciation: submit paid invoices to release holdback amounts.
6
If smoke odor persists after cleaning, request a supplemental air-quality or HVAC duct scope.

Phase 02 · Preparation

Document checklist

Gather these before filing to reduce back-and-forth with the adjuster.

Wide-angle and close-up photos of all affected rooms
Fire department incident report
Restoration contractor line-item estimate (Xactimate or equivalent)
Inventory of soft goods sent for professional cleaning
HVAC inspection report if odor travels through ducts
Code upgrade quotes (wiring, drywall, insulation)
Hotel or additional living expense receipts if displaced
Paid contractor invoices for depreciation release

Risk watchlist

Common reasons claims get denied

These show up most often in adjuster decisions for this claim type. Knowing them in advance usually changes how you document the loss.

Smoke damage classified as cosmetic only

Odor and soot can require duct cleaning and sealed encapsulation—document with air tests.

Code upgrade costs excluded

Ordinance or law coverage may be required; cite the endorsement or its absence in writing.

Personal property cleaned vs. replaced dispute

Itemize soft goods with professional cleaning invoices and replacement quotes.

Vacancy or business-use exclusions

Confirm occupancy status at time of loss on the declarations page.

Arson investigation pending

Cooperate with fire marshal; carrier may pause payment until cause is determined.

Timeline

What slows a claim down

Most delays come from these causes — often fixable with a single phone call or follow-up email.

Waiting for cause-and-origin report

Fire investigations can pause payment 2–6 weeks.

Supplement review after initial payment

Hidden char behind walls often surfaces during tear-out.

Mortgage company endorsement on large checks

Lender may require inspections before funds release.

Be ready

Supplemental documents you may be asked for

Adjusters routinely request additional records during review. Being ready keeps a claim from stalling.

Odor returns after initial cleaning

Third-party smoke remediation scope with encapsulation product specs.

Electrical code upgrades during rebuild

Local code citations and electrician letter requiring AFCI/GFCI updates.

Escalation

If your claim is denied, delayed, or short-paid

Concrete next steps for readers who hit a wall. Each one is a recognized consumer right or documented escalation path.

Paper trail

Talking to the carrier and your state regulator

How you communicate matters. These notes help you keep a written paper trail and use language carriers and state DOIs recognize.

Confirm verbal commitments in a follow-up email with deadlines.
Log adjuster name, direct line, and supervisor contact on every call.
Use claim number and policy number in every email subject line.
