What Licensing and Insurance Do You Carry?
One of the first questions to ask any commercial kitchen exhaust cleaning provider is about their licensing and insurance. In the United States, regulations vary by state and municipality, but a legitimate company should always carry general liability insurance and workers’ compensation coverage. Ask for a copy of their certificate of insurance and verify that it is current. Without proper insurance, you could be held liable for accidents or property damage that occur during the cleaning process. Additionally, many local fire codes require that hood cleaning companies hold specific trade licenses. Never hire a company that cannot provide clear proof of both licensing and insurance.
Do You Follow National Fire Protection Association (NFPA) 96 Standards?
NFPA 96 is the standard for ventilation control and fire protection of commercial cooking operations. A reputable hood cleaning company should be intimately familiar with these guidelines. Ask specifically how they ensure compliance with NFPA 96, including cleaning schedules, documentation, and inspection points. The company should clean all components of the exhaust system — hoods, filters, ducts, fans, and roof exhaust units — down to bare metal. If a company cannot articulate how they meet NFPA 96 standards, it is a red flag. Compliance is not optional; it is essential for passing local fire inspections and maintaining your business insurance.
Can You Provide References or Online Reviews from Local Restaurants?
Before committing to a service, request references from other commercial kitchens in your area. A trustworthy company will gladly share contact information for current clients. You can also check Google, Yelp, and the Better Business Bureau (BBB) for reviews. Pay close attention to comments about punctuality, thoroughness, and customer service. If a company has multiple unresolved complaints or a pattern of missed appointments, consider that a warning. Local references are especially valuable because they indicate the company understands the specific fire codes and health department requirements in your city or county.
What Is Included in Your Standard Cleaning Service?
Not all hood cleaning services are created equal. Some companies offer a basic filter cleaning, while others provide a comprehensive exhaust system cleaning. Ask for a detailed list of what is included in their standard package. A thorough service should include cleaning of the hood interior and exterior, all filters, the exhaust ductwork from the hood to the roof, the exhaust fan blades and housing, and any grease traps or drip pans. The company should also remove and replace filters properly, and clean the roof area around the exhaust fan. If the scope of work is vague, ask for a written checklist. You need to know exactly what you are paying for to avoid costly add-ons later.
How Do You Handle Grease Disposal and Environmental Compliance?
Proper disposal of grease and cleaning waste is an environmental and legal requirement. Ask the company how they collect, transport, and dispose of grease and chemical residues. They should follow all Environmental Protection Agency (EPA) and local environmental regulations. Some companies simply wash grease into storm drains, which is illegal and can result in heavy fines for your business. A responsible company will use absorbents, vacuum systems, or approved disposal methods. Request to see their waste disposal manifests or certificates to confirm they are compliant. This question protects both the environment and your restaurant’s reputation.
Do You Provide a Detailed Report and Certificate of Compliance After Each Cleaning?
After every service, you should receive a written report detailing the work performed, including photographs of the cleaned system. Many fire departments and insurance companies require this documentation for inspections. A certificate of compliance, sometimes called a “cleaning certificate,” proves that your exhaust system meets NFPA 96 standards. Ask the company if they provide digital or printed reports and how quickly they can deliver them. If they do not offer this documentation, it will be difficult to prove compliance during a fire marshal visit. This paperwork is your best defense in the event of a fire or insurance claim.
What Is Your Pricing Structure? Are There Hidden Fees?
Pricing for commercial hood cleaning varies based on the size of your kitchen, the length of ductwork, and the frequency of service. Request a written quote that breaks down all charges. Ask specifically about potential extra fees for heavy grease buildup, after-hours service, or additional equipment like rooftop fans. Some companies offer a low base price but add significant surcharges later. A transparent company will provide a fixed price or a clear hourly rate with no surprises. Compare quotes from at least three providers, but remember that the cheapest option is not always the best. Quality and compliance should be your top priorities.
How Often Should My Kitchen Be Cleaned, and Can You Set Up a Schedule?
NFPA 96 recommends cleaning schedules based on the volume of cooking and the type of food prepared. For example, a high-volume fast-food restaurant may need monthly cleaning, while a low-volume café might require quarterly service. Ask the company to evaluate your operation and recommend a frequency that meets code requirements. They should also be able to set up a recurring schedule so you never miss a cleaning. Consistent service helps prevent grease buildup, reduces fire risk, and keeps your kitchen running efficiently. A good company will also send reminders before each scheduled visit.
What Happens If a Fire Inspector Finds Violations After Your Cleaning?
This question tests the company’s accountability. A confident and reliable company will stand behind their work. Ask if they offer a guarantee that their cleaning will pass a fire inspection. Some companies will return at no charge to address any issues found by an inspector within a certain timeframe. Clarify the terms of this guarantee before hiring. If a company hesitates or refuses to offer any assurance, it may indicate that their work is inconsistent. You want a partner who is committed to keeping your kitchen safe and compliant, not just one who collects a payment.
