Commercial Kitchen Hood Cleaning Services for Code Compliance & Safety

In today’s highly regulated food service industry, maintaining a clean, compliant, and fire-safe commercial kitchen is essential—not just for day-to-day operations but for protecting your business, staff, and customers. One of the most overlooked but critical components of a safe kitchen environment is the kitchen exhaust hood system, which includes the hood canopy, plenum, grease filters, exhaust ducts, and rooftop fan.
Without regular and thorough commercial kitchen hood cleaning, grease-laden vapors from cooking accumulate rapidly throughout the ventilation system. This buildup becomes a highly flammable fire hazard, reduces airflow, impairs kitchen efficiency, and can lead to serious violations of NFPA 96 fire code, health inspections, and OSHA safety regulations. Failure to properly clean the system may even void your insurance coverage in the event of a fire.
Capital Steam Hood Cleaners provides specialized kitchen exhaust system cleaning services that meet or exceed NFPA 96 standards for ventilation control and fire protection of commercial cooking operations. We proudly serve food service establishments across California, including:
Full-service restaurants
Fast food franchises
School cafeterias
Assisted living and senior care kitchens
Hotels and resorts
Commercial commissary and ghost kitchen
With over 28 years of hands-on experience, we understand the unique ventilation requirements of each kitchen type. Our team uses state-of-the-art equipment—such as industrial steamers, high-pressure degreasers, and rotary duct cleaning tools—to remove grease from every component of your hood system, including hard-to-access vertical ducts and rooftop fans. We also install and maintain hinge kits, grease containment systems, and access panels to ensure your kitchen remains compliant and easy to service in the future.
Whether you need a one-time deep clean or a scheduled exhaust system maintenance program, Capital Steam Hood Cleaners delivers NFPA 96-compliant results, detailed service documentation, and peace of mind—so you can focus on running a successful kitchen.
Why Professional Kitchen Hood Cleaning is Crucial
1. Fire Hazard Mitigation
Grease vapors produced during commercial cooking rise into the kitchen exhaust hood, where they cool and condense into thick, flammable grease deposits inside the hood plenum, exhaust ducts, and upblast exhaust fan housing. Over time, this buildup poses a serious fire risk. According to the National Fire Protection Association (NFPA), nearly one-third of restaurant fires originate in the kitchen exhaust system, typically due to ignition of accumulated grease.
Professional kitchen hood cleaning services ensure the complete removal of combustible grease from all components of your Type I hood system. Our trained technicians use high-pressure steam cleaning, food-safe degreasers, and rotary duct scrubbers to eliminate flammable residues and minimize your kitchen’s fire risk. We also provide post-cleaning inspection reports and certification stickers—critical documentation required by fire inspectors and insurance providers.
2. Compliance with NFPA 96 & Local Fire Codes
Commercial kitchens are legally required to adhere to NFPA 96—the national standard for ventilation control and fire protection in commercial cooking operations. This includes routine exhaust hood system cleaning intervals based on the volume and type of cooking:
Monthly for high-volume kitchens (e.g., 24-hour diners, wok cooking, charbroiling)
Quarterly for moderate-use kitchens (e.g., fast food, family restaurants)
Semi-annually or annually for low-volume or seasonal kitchens
Failure to comply may result in:
Health and fire code violations
Business license suspension
Voided insurance claims
Costly fines and downtime
At Capital Steam Hood Cleaners, our services are fully aligned with NFPA 96 standards, local health codes, and city fire ordinances throughout California. Our team provides certified commercial kitchen exhaust cleaning, ensuring your business remains compliant and protected during inspections.
3. Improved HVAC Performance and Indoor Air Quality
Grease and dirt accumulation inside the ventilation hood and duct system restrict airflow, which puts strain on your HVAC system and creates an unbalanced air environment. This not only reduces the efficiency of kitchen exhaust fans, but also:
Circulates unpleasant cooking odors
Contributes to humidity and heat buildup
Causes poor employee working conditions
Increases energy consumption and costs
Our comprehensive kitchen ventilation cleaning services remove grease buildup from hood filters, ductwork, and fan blades, restoring your kitchen’s airflow capacity. Clean systems promote better air circulation, lower utility costs, and a safer, more comfortable cooking environment for chefs and staff.
Key Components We Clean and Service
Hood Plenum and Grease Extractors
We thoroughly degrease the plenum (air reservoir above the filters) and clean or replace baffle filters, ensuring maximum grease capture and airflow.
Horizontal and Vertical Ductwork
Our technicians access and clean hard-to-reach ductwork using installed access panels, rotary scrubbers, and high-pressure steam equipment to remove grease buildup.
Roof-Mounted Exhaust Fans and Fan Hinges
We install and service hinge kits that allow safe access to upblast fans for cleaning the fan blades, housing, and shroud. This protects your roof, fan motor, and ensures fire code compliance.
Grease Containment Systems
We install rooftop grease containment systems that trap and safely hold excess grease, preventing it from damaging the roof membrane or flowing into storm drains.
Understanding NFPA 96 Cleaning Frequency Requirements
The National Fire Protection Association specifies how often commercial kitchen exhaust systems should be cleaned based on their use:
Kitchen Type | Cleaning Frequency |
High-volume (e.g., fast food) | Monthly |
Moderate-volume (e.g., full-service restaurant) | Quarterly |
Low-volume (e.g., seasonal kitchen) | Semi-annually |
Non-grease cooking (e.g., steamers) | Annually |
At Capital Steam Hood Cleaners, we customize a scheduled maintenance plan to ensure your kitchen always meets NFPA 96 standards.
