Commercial kitchen exhaust cleaning is a specialized trade with an unusual risk profile. Contractors work around cooking appliances, live electrical components, rooftops, exhaust fans, ductwork, heavy grease deposits, water, and caustic chemicals, often after hours and inside somebody else’s building.
An accident on that job can damage expensive property or injure someone on site. Commercial general liability insurance, commonly called GL or CGL insurance, sits at the foundation of a hood cleaning contractor’s insurance program for exactly that reason.
What General Liability Covers
A general liability policy may respond when a contractor becomes legally responsible for covered bodily injury or property damage. Common scenarios in this trade include:
- A restaurant employee slipping on a hose or a wet surface left during service
- Cleaning solution damaging nearby flooring, finishes, or kitchen equipment
- A tool or piece of equipment falling from a rooftop and damaging property below
- Water intrusion from the cleaning process reaching an area below the hood
- Damage to a customer’s fan motor, wiring, or ductwork during service
The policy may also provide a legal defense when the contractor is sued over a covered incident, and defense costs alone can exceed the value of the underlying claim. Coverage still depends on the facts of the claim, the cause of the damage, and the exclusions and endorsements attached to the specific policy.
Coverage Does Not End When the Crew Leaves
One of the most important points for hood cleaners: general liability is not limited to accidents that happen while the crew is physically on site.
A standard occurrence-based GL policy usually includes products-completed operations coverage, which may respond to certain bodily injury or property damage occurring after the work has been completed. Given that the most severe claims in kitchen exhaust cleaning tend to involve a fire weeks or months after service, this portion of the policy carries enormous weight.
Completed-operations coverage does not mean every complaint about a finished job finds coverage. The scope has limits, and understanding them prevents an unpleasant conversation during a claim.
What General Liability Is Not
General liability is not a warranty or a performance guarantee. The policy is generally not intended to pay because a customer is dissatisfied, because the cleaning needs to be performed again, or because part of the system was not cleaned as thoroughly as the contract promised.
The critical difference comes down to one question: does the claim involve the cost of redoing the contractor’s own work, or does it involve bodily injury or damage to other property resulting from that work?
Redoing the work is typically a business cost. Damage to the building, the equipment, or a person resulting from the work is where general liability engages. Allegations about the accuracy of a service report or the quality of an inspection move into professional liability territory, which is a separate conversation covered in more depth elsewhere on this site.
Certificates of Insurance and What They Actually Prove
Restaurants, franchise groups, property managers, and general contractors routinely require a Certificate of Insurance before allowing a hood cleaning company to start work. Vendor-compliance platforms have made this requirement close to universal in the national account space.
A COI provides evidence that certain policies and limits were in place on the date the certificate was issued. Two limitations deserve attention:
- A certificate does not create coverage. It reports what a policy said at a moment in time.
- A certificate does not make the customer an additional insured. Additional-insured status must be supported by the actual policy or by an endorsement that satisfies the requirements written into the service contract.
Contracts frequently call for specific endorsement forms, primary and non-contributory wording, or waivers of subrogation. Matching the policy to the contract language before signing prevents a compliance problem after the work is done and the invoice is waiting on approval.
The Limits on the Certificate Tell a Small Part of the Story
General liability is an essential starting point for a kitchen exhaust cleaning business. A certificate showing a $1,000,000 limit still tells only a fraction of the story.
Contractors benefit from confirming several details with their carrier:
- Accurate classification. Kitchen exhaust cleaning operations described accurately at application, including rooftop work, pressure washing, and any minor repairs performed
- Completed operations included, with limits that reflect the fire exposure this trade carries
- Exclusions identified, particularly pollution exclusions, height restrictions, hot-work exclusions, and any restriction on subcontracted labor
- Scope of services matched to what the business actually sells, including filter exchange programs, fan repairs, grease containment, and access panel installation
In this trade, the limits shown on the certificate are the cover of the book. The details that decide claims live inside the policy form.
Building the Rest of the Program
General liability functions as the foundation, not the whole structure. A complete program for a kitchen exhaust cleaning company usually includes workers’ compensation for crew injuries, commercial auto for the trucks, inland marine for pressure washers and equipment, professional liability for inspection and reporting exposure, and pollution liability for the chemicals and wastewater.
Working with an insurance broker who specializes in kitchen exhaust cleaning helps ensure the business is classified correctly, important exclusions are identified before a claim rather than after, and coverage is structured around how the operation actually runs.
Frequently Asked Questions
What does general liability cover for a hood cleaning company?
Covered bodily injury and property damage arising from operations and completed work, along with legal defense for covered claims. Slips, chemical damage to finishes, dropped tools, and post-service fire damage are common examples.
Does general liability cover a fire caused by an incomplete cleaning?
Resulting property damage may fall under the products-completed operations portion of the policy, subject to the facts and the policy’s exclusions. Allegations centered on an inaccurate service report or a negligent inspection typically belong to professional liability.
How much general liability insurance do kitchen exhaust cleaners need?
Many service contracts specify $1,000,000 per occurrence and $2,000,000 aggregate. Restaurant groups, property managers, and national accounts often require higher limits or an umbrella policy on top.
Does a Certificate of Insurance make a customer an additional insured?
No. Additional-insured status requires an endorsement on the policy itself. The certificate simply reports what coverage existed when it was issued.
