What Insurance Carriers Want to See After a Kitchen Grease Fire
If your kitchen has a fire, your insurer will demand a documented hood-cleaning history. Here is exactly what they ask for — and how to keep it ready before you need it.
A grease fire is bad. A denied claim afterward is worse. Commercial kitchen insurers have tightened up dramatically since 2020, and the first thing they ask for after any kitchen fire — even one that was suppressed in under a minute — is your hood-cleaning service history. This article walks through the standard request, why each item matters, and how to keep the documentation ready before you actually need it.
The standard documentation request
After a fire, expect your carrier or their independent adjuster to request, in writing, within 48 hours of the loss:
- Every cleaning service report for the prior 24 months
- The cleaning company's contractor license and current insurance certificate
- Timestamped before-and-after photos of the system from each cleaning
- Any reports flagging inaccessible areas, missing access panels, or deferred work
- The most recent suppression-system semi-annual inspection tag
- Your filter-replacement log, if you maintain one
- Any communications with your cleaning vendor about deferred service or skipped visits
Most carriers want all of it as a single PDF within five business days. Operators who scramble to assemble it after the fire are at a significant disadvantage.
Why each item matters
Carriers are looking for two things: a pattern of compliance, and any document that contradicts your application.
If your policy was written assuming quarterly cleaning and your reports show annual cleaning, that is grounds for denial in most states, California included. If your application said you do not run a solid-fuel grill and the photos show charcoal residue in the plenum, that is grounds for denial. The single most common reason commercial kitchen claims are denied is not the fire itself — it is a mismatch between what the operator told the carrier at underwriting and what the cleaning history shows.
The 'inaccessible areas' problem
If a section of your duct could not be cleaned because of design (missing panels, welded plenum, blocked horizontal run that passes through another tenant's space), that has to be on the report — every time, with photos. A clean report that does not flag a known inaccessible area can be treated by the carrier as a misrepresentation by the cleaning contractor, and that representation flows through to you.
The right move when you discover an inaccessible area is to schedule the access-panel installation immediately and keep the proposal, the work order, and the post-install photos in the same folder as your service reports. That paper trail shows the carrier you took action the moment you knew.
We have seen six-figure claims paid in full because the operator handed the adjuster a binder. We have seen claims denied because the operator could not produce a single dated photo.
What 'paid in full' actually looks like
On the well-documented end: a Walnut Creek operator had a flash fire on a charbroiler in 2024. The suppression system fired correctly, the duct stayed cool, the loss was about $38,000 in equipment and three days of business interruption. The carrier paid in full within 21 days because the operator had quarterly reports with photos, a current suppression tag, and a filter log. The adjuster never asked a second question.
On the other end: a San Jose operator with the same fire size, no service reports for 14 months, and an expired suppression tag. The carrier denied the claim citing misrepresentation on the renewal application (which stated quarterly cleaning). The operator absorbed the full loss and lost the policy at renewal.
Keep the records yourself
Cleaning companies come and go. Save every digital report to your own cloud drive — Google Drive, Dropbox, OneDrive, whatever you already use — the day it arrives. Use a consistent naming convention: YYYY-MM-DD_hood-cleaning_vendor-name.pdf. If you change vendors, you still want the prior history, and your old vendor is under no obligation to keep their records past their own retention period.
Take it one step further: every quarter, take 30 seconds to email the latest report to yourself with the subject line 'Hood cleaning report — [date].' That creates a second, time-stamped copy in your sent folder that no one can backdate.
The five-minute pre-loss checklist
- Last two service reports saved to cloud, with photos
- Suppression-system tag photographed monthly during opening checks
- Filter swap dates logged on a clipboard or shared note
- Insurance application reviewed annually — does it still match what you actually do?
- Vendor's current insurance certificate on file
Five minutes a month. It is the cheapest insurance against the most expensive surprise in this business.
