(SERVICE OVERVIEW)

What is Restaurant Kitchen Exhaust System Cleaning?

A commercial kitchen exhaust system is designed to carry heat, steam, and vaporized grease away from the cooking line. However, as grease cools, it accumulates on duct walls, filters, and fan blades. This thick grease accumulation is highly flammable and constitutes the primary cause of kitchen fires.

Our restaurant exhaust system cleaning involves a comprehensive scraping and high-pressure steam washing of the entire system. We clean all accessible portions of the exhaust line down to bare metal, applying official certification labels to satisfy fire inspectors, health officials, and insurance requirements.

(CRITICAL HYGIENE & SAFETY)

Why Restaurant Exhaust System Cleaning Matters

Routine exhaust system maintenance is critical to keeping your restaurant safe, legal, and operational. Here is why it is essential:

Absolute Fire Safety

Over 70% of restaurant fires start in the kitchen ventilation ducts. Thoroughly removing grease blockages down to bare metal eliminates the fuel source.

Fire Marshal Compliance

NFPA 96 codes dictate regular certified cleaning schedules for kitchen exhaust systems. Non-compliance results in heavy fines or immediate closure.

Proper Air Ventilation

A grease-choked duct restricts airflow, keeping heat, odors, and smoke trapped inside the kitchen, leading to a hot and hazardous work environment.

(SYSTEM WARNING SIGNS)

Signs Your Exhaust System Needs Immediate Cleaning

Watch for these common warning signals in your restaurant's ventilation. If present, book a deep clean immediately:

Heavy Grease Coating Filters

Filters that look thick, sticky, or blocked prevent grease vapors from venting properly.

Haze and Smoke in Kitchen

A constant smoke haze during cooking hours shows that exhaust draw is severely obstructed.

Oil Dripping from Duct Seams

Grease escaping from ductwork connections inside the ceiling or walls indicates an overloaded system.

Loud Exhaust Fan Noises

Screeching or vibration from the rooftop fan means grease weight has thrown the blades out of balance.

Rancid Oil Odors

Burnt grease smells leaking into the dining area ruin guest experiences and point to system neglect.

Overdue Inspection Date

The compliance sticker on the hood indicates your cleaning window has expired according to local regulations.

(HOW WE WORK)

Our Step-by-Step Process

We employ a meticulous, structured process to ensure safety, efficiency, and zero mess left behind:

01

Site Protection & Draping

We wrap kitchen appliances, prep tables, and floors in heavy plastic sheeting to catch all water and grease runoff.

02

Rooftop Inspection

Our technicians access the roof to inspect the upblast fan, belt, bearings, and motor electrical connections.

03

Filter Soaking & Plenums

We remove the baffle filters, place them in a chemical soak tank, and scrape away thick grease layers from the hood canopy.

04

Chemical Degreasing Foam

We apply heavy-duty, biodegradable chemical degreaser to the entire duct network and rooftop fan assembly.

05

Pressure Steam Flush

We use high-temperature pressure washers (200°F+) to flush grease out of the duct runs and into containment bins.

06

Detailing & Sanitize

Technicians dry all ductwork, polish the hood canopy, clean the exhaust filters, and mop the kitchen floors.

07

Compliance Documentation

We apply a dated NFPA 96 compliance label and send a comprehensive before-and-after digital photo log.

(GOT QUESTIONS?)

Frequently Asked Questions

Got questions about Restaurant Kitchen Exhaust System Cleaning schedules, compliance, or logistics? Find detailed answers below:

A compliant exhaust cleaning covers the entire system. This includes the hood canopy, the plenum (the area behind the filters), all vertical and horizontal duct runs, and the rooftop exhaust fan blades and housing. Cleaning only the hood is a major code violation.
It typically takes 3 to 5 hours. The duration depends on the length of the duct runs, the number of hoods, and the level of grease accumulation. We perform our services overnight or during closed hours to ensure zero business disruption.
Cleaning frequency is governed by NFPA 96. Monthly cleaning is required for solid-fuel cooking (wood/charcoal). Quarterly cleaning is standard for high-volume operations (fast food, charbroiling). Semi-annual cleaning is needed for moderate-volume kitchens, and annual cleaning is sufficient for churches or seasonal operations.
Yes. We document our work from start to finish. You will receive a complete digital photo log showing the interior of the hoods, ducts, and rooftop fan before and after our service, providing proof of a thorough clean.
Neglecting your exhaust system creates a severe fire hazard, violates fire codes, and can result in immediate closure by fire marshals. It also causes poor kitchen ventilation, bad odor, premature fan motor failure, and can void your business insurance policy.
Yes. All Crossaire technicians are fully NFPA 96 certified commercial exhaust cleaners. We apply the official dated compliance stickers required by fire marshals, health inspectors, and insurance adjusters.
