Short answer: Commercial kitchen hood cleaning is required under NFPA 96 at intervals ranging from monthly to annually depending on your cooking volume. Most Jacksonville full-service restaurants fall into the quarterly bucket; fast-food and high-volume operations are monthly. Skip it and you risk failed health inspections, insurance claim denial after a grease fire, and — in severe cases — a fire marshal shutdown until remediation is complete.

If you own or manage a restaurant in Jacksonville, commercial kitchen hood cleaning is not optional. It is required by fire code, health regulations, and your own insurance policy. It is also one of the most commonly overlooked maintenance items in the food-service industry, and the one with the highest cost-of-skipping ratio.

Why Hood Cleaning Matters

Fire Prevention

Grease-laden vapor from cooking rises into your exhaust hood, travels through ductwork, and exits through a rooftop fan. Along the way, a film of grease accumulates on every surface. Over weeks and months, that film builds into a sticky, highly flammable coating.

According to the National Fire Protection Association, cooking equipment is the leading cause of restaurant fires, and dirty exhaust systems are a major contributing factor in rapid-spread fires. The NFPA estimates that roughly 1 in 10 restaurant fires involve exhaust ductwork ignition.

A grease fire in an uncleaned hood system is different from a stovetop fire. It can travel the full length of the ductwork in seconds, reaching the roof and spreading across the building's exterior roofing before the suppression system or fire crew can catch it. By that point the damage is catastrophic and the kitchen is closed for weeks or months.

Health Code Compliance

The Florida Department of Business and Professional Regulation (DBPR) and local Duval County health inspectors check hood and exhaust system cleanliness during routine restaurant inspections. Visible grease buildup on hoods, filters, and accessible ductwork can result in:

Point deductions on your inspection score, which is publicly posted
Required re-inspection within a short timeframe (cost and disruption)
Fines for repeat violations
Temporary closure in severe cases, particularly if combined with other violations

Insurance Requirements

Most commercial kitchen insurance policies require documented hood cleaning as a condition of coverage. If a fire occurs and your hood system has not been professionally cleaned on the schedule specified in your policy, your carrier can deny the claim entirely. Read your policy — the cleaning frequency is usually in the "warranty" or "protective safeguards" section.

This is the single most expensive oversight restaurants make. A denied claim on a grease fire averages six-figure losses that a $400 quarterly cleaning would have prevented.

NFPA 96 Cleaning Frequency Requirements

NFPA 96 — the standard for ventilation control and fire protection of commercial cooking operations — establishes minimum cleaning frequencies based on the type and volume of cooking:

Cooking Type	Cleaning Frequency
High-volume (24-hour operation, charbroiling, wok, solid fuel)	Monthly
Moderate-volume (full menu, standard hours, typical full-service restaurants)	Quarterly
Low-volume (churches, day camps, seasonal operations, limited menu)	Semi-annually
Low-volume (no deep frying, minimal grease generation)	Annually

Most full-service restaurants in Jacksonville fall into the quarterly category. Fast-food restaurants with fryers and grills often require monthly cleaning. Solid-fuel cooking (wood, charcoal) is almost always monthly regardless of volume.

Always confirm your specific frequency with your insurance carrier and local fire marshal — some jurisdictions and policies exceed the NFPA minimum.

What Professional Hood Cleaning Actually Includes

A comprehensive hood cleaning service covers every component of the exhaust system, not just the visible hood surface. Anyone skipping ductwork or the rooftop fan is leaving the most flammable accumulation untouched.

Hood and Baffle Filters

Baffle filters removed, soaked in a hot-water caustic tank, and degreased
Hood interior scraped and cleaned to bare metal
Hood exterior cleaned and polished
Filter racks cleaned and inspected for damage

Ductwork

Full access to ductwork through access panels (installed if missing)
Interior surfaces scraped to bare metal where accessible
Horizontal runs given special attention — grease pools and accumulates here, and this is where most serious fires start
Ductwork photographed before and after for documentation

Exhaust Fan

Fan blades and housing cleaned
Hinge kit inspected for proper operation
Rooftop curb and grease containment verified and serviced
Belt and motor inspected for wear

Rooftop and Grease Containment

Grease cup or containment pad replaced if saturated
Rooftop area around the fan cleaned and verified grease-free (fire spread risk)

Documentation

This is the part many low-cost services skip, and it is the most important:

Before and after photos provided
Certificate of compliance issued (NFPA 96 format)
Sticker placed on the system with cleaning date, next due date, and the cleaning company's certification number
Digital copy emailed for your insurance file

Choosing a Hood Cleaning Service in Jacksonville

Not every commercial cleaning company is qualified for hood work. When selecting a service, verify:

Certification — look for technicians certified by the International Kitchen Exhaust Cleaning Association (IKECA) or equivalent
Insurance — the company should carry specific liability insurance for hood cleaning work (general liability is not enough)
Documentation — professional companies provide certificates in the format that fire marshals and health inspectors expect
After-hours availability — cleaning should be done when the kitchen is closed to avoid contamination, which means late-night or early-morning visits
Access-panel policy — competent companies install missing access panels as part of the job, not as a surprise upcharge
Written scope — what surfaces are covered, what is not, and what extra costs trigger (like roof-fan motor service)

What a Hood Cleaning Visit Actually Looks Like

A typical Jacksonville restaurant hood cleaning runs 3 to 6 hours depending on hood length, cooking volume since last cleaning, and ductwork complexity. We schedule after close (usually 11 PM to 4 AM) so the kitchen is ready for prep at the normal opening time.

The sequence:

Plastic-tarp the cookline and surrounding area to contain runoff and cleaning chemicals
Remove filters, load into soak tank so they clean in parallel with the hood work
Scrape and wash the hood interior, cookline hood exterior, and plenum
Open access panels and scrape ductwork down to bare metal where accessible
Clean the exhaust fan on the roof, including blade and housing
Check and service grease containment
Rinse and degrease every surface we touched
Re-install filters (or replace if rusted through)
Pull tarps, wipe down cookline, issue certificate and sticker

Don't Wait for an Inspection

The worst time to discover your hood system needs cleaning is during a surprise health inspection, a fire marshal visit, or — worst of all — at 2 AM when a grease fire lights up the ductwork. Proactive scheduling keeps you compliant, protects your business, your staff, and your customers, and satisfies your insurance carrier.

Most Jacksonville restaurants we serve are on a standing calendar: a monthly or quarterly recurring visit scheduled automatically, certificate filed to their email, sticker updated on the hood. It is the lowest-friction way to stay compliant and the easiest item to explain to a fire marshal who walks in on a Tuesday morning.

Frequently Asked Questions

How much does commercial hood cleaning cost in Jacksonville? Most Jacksonville restaurants pay $300 to $700 per quarterly visit depending on hood length, ductwork complexity, and fan accessibility. Monthly schedules are typically discounted per-visit because the system never gets deeply soiled.

What if I just had the hood cleaned by the previous tenant? Get the certificate before taking over the lease. If there is no documentation, assume the system is out of compliance and schedule a first cleaning before opening.

Do you work with chain restaurants and franchise operators? Yes. We handle single-unit independents, multi-unit operators, and franchise locations. We can bill corporate and service multiple locations on a synchronized calendar.

Is hood cleaning really regulated in Duval County? Yes. The fire marshal enforces NFPA 96, the health department checks during inspections, and your insurance carrier expects documented compliance. All three have authority that affects your ability to operate.

Commercial hood cleaning is a compliance item, not a cleanliness preference. We are NFPA 96 certified, fully insured, and issue the documentation fire marshals and inspectors expect. Schedule a standing calendar so you never have to think about it again.
