How often does a restaurant hood need to be cleaned?

NFPA 96 requires monthly cleaning for solid-fuel operations, quarterly for high-volume and charbroiling kitchens, every 6 months for typical full-service restaurants, and annually for low-volume operations.

Does hood cleaning affect my insurance?

Yes. Most commercial property insurance policies for restaurants require NFPA 96 compliant hood cleaning as a condition of coverage. Failure to maintain cleaning records can result in denied claims following a fire.

What documentation do I get after a hood cleaning?

Grand Natural provides a dated service certificate after every cleaning that includes the technician's license number, scope of work, and signature. This certificate satisfies insurance carrier and health department requirements.

Do you also inspect the fire suppression system?

Yes. Every Grand Natural hood cleaning service includes a visual inspection of the fire suppression system including nozzles, tanks, and manual pull stations.

How long does a hood cleaning take?

Cleaning time depends on the size and configuration of your exhaust system and how much grease has accumulated since the last cleaning. Most restaurant hood cleanings take 2-4 hours and are performed during off-hours.

Why Hood Cleaning Is Not Optional

Kitchen exhaust hood systems accumulate grease deposits with every hour of cooking. Over time, this grease buildup becomes a serious fire hazard — grease fires in restaurant kitchens are one of the leading causes of commercial structure fires in the United States. NFPA 96, the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, mandates that exhaust systems be professionally cleaned on a frequency based on cooking volume and fuel type.

Beyond fire risk, commercial property insurance policies for restaurants typically include provisions requiring NFPA 96 compliance as a condition of coverage. A fire caused by a grease buildup in an uncleaned hood system can be grounds for an insurer to deny a claim — even if the restaurant had an active policy at the time of the loss.

Required Cleaning Frequency Under NFPA 96

NFPA 96 establishes minimum cleaning frequencies based on cooking type:

Monthly: Systems serving solid-fuel cooking operations (wood, charcoal)
Quarterly: High-volume cooking operations, 24-hour restaurants, charbroiling
Every 6 months: Moderate-volume operations, typical full-service restaurants
Annually: Low-volume cooking operations, seasonal use, churches, day camps

Grand Natural schedules your hood cleanings based on your specific kitchen operation type to ensure compliance at the correct interval.
