If you searched “hood cleaners,” you’re probably trying to solve one of three problems: your exhaust hood is overdue for cleaning, your fire marshal or insurer flagged it, or you’re comparing companies and don’t know what actually separates a good one from a risky one. This guide answers all three – what hood cleaners do, what the code requires in Ontario, and exactly what to check before you hire someone to work on your kitchen’s fire-safety system.
This guide is written and maintained by Fast Hood Cleaners, an NFPA 96–certified hood cleaning company based in Oakville, Ontario, serving commercial kitchens across the Greater Toronto Area. Everything below reflects the standards our technicians are trained to and the documentation we provide on every job – not generic advice pulled from a blog template.
What Are Hood Cleaners, Exactly?
“Hood cleaners” is the common term for technicians and companies that clean commercial kitchen exhaust systems – the hood above your cooking line, the ductwork running up through the building, the exhaust filters, and the rooftop fan unit. Their job is to strip built-up grease down to bare metal along the entire exhaust path, not just wipe the visible steel surface.
This is different from general cleaning staff or a handyman with a degreaser and a ladder. Hood cleaners work to a specific fire-code standard – NFPA 96 in North America – which sets requirements for how often systems must be cleaned, how thoroughly (bare metal, not just “visibly clean”), and what documentation has to be left behind for inspectors and insurers.
Why Hood Cleaning Isn’t Optional
Grease that accumulates inside an exhaust hood and duct system is combustible. It’s one of the best-documented causes of commercial kitchen fires, and it’s exactly the kind of hazard fire marshals and insurance adjusters look for during inspections and after a loss. That’s why:
- Fire codes require it. NFPA 96 sets minimum cleaning frequencies based on cooking volume.
- Insurers require proof of it. A claim after a kitchen fire can be denied if there’s no documentation showing the exhaust system was cleaned on schedule.
- Health inspectors check for it. Grease buildup around cooking equipment is a food-safety flag, not just a fire-safety one.
- It protects staff and customers, not just the building – grease fires spread fast through ductwork.

What Do Professional Hood Cleaners Actually Do?
A proper hood cleaning job follows a defined sequence, not a quick spray-and-wipe. Here’s what it looks like when it’s done to code:
- Inspection of the kitchen and exhaust system before any work starts.
- Protection — all equipment, food prep areas, and surfaces near the hood are covered with plastic sheeting.
- Filter removal and the exhaust system is sealed off for cleaning.
- Degreasing — commercial-grade degreasers are applied to the hood, ductwork, and vent.
- Pressure washing the entire hood system, ductwork, and filters down to bare metal.
- Rooftop fan cleaning — the fan unit is one of the most overlooked parts of the system and is pressure washed as part of a compliant job.
- Filter treatment — filters are chemically treated and pressure washed separately.
- Full detail of the exterior, interior, sides, and backsplash of the hood.
- Drying and reassembly, followed by a final inspection.
- Documentation — before-and-after photos, a health & safety certificate, and an inspection report are provided so you have proof for your fire marshal, health inspector, and insurer.
That last step is the one most self-cleaning attempts and unlicensed operators can’t provide – and it’s usually the actual thing an inspector or adjuster is asking to see.
Hood Cleaners vs. Exhaust Cleaners vs. Flue Cleaners
These terms get used interchangeably, but they don’t always mean the same scope of work.

How to Choose the Right Hood Cleaning Company: A Checklist
Not every company advertising “hood cleaning” is certified to NFPA 96 standards, and the paperwork gap usually only shows up when you actually need it – during an inspection or an insurance claim. Before you hire hood cleaners, check for these six things:
1. Certification to NFPA 96.
Ask directly which code the technicians are trained to and who certified them. Fast Hood Cleaners’ technicians are certified by MFS Trade School to NFPA 96 standards.
2. Licensing and insurance.
Your hood cleaner is working around grease, degreasers, and rooftop equipment. Confirm they’re licensed and carry insurance that covers the job – not just a business name on an invoice.
3. Documentation you can actually hand to an inspector.
Ask what you receive after the job. It should include before/after photos, a health & safety certificate, and an inspection report – not just a paid invoice.
4. Bare-metal cleaning, not surface wiping.
Ask how they clean the ductwork and rooftop fan specifically. If the answer only covers the visible hood surface, that’s not a compliant clean.
5. Experience with your kitchen type.
Hospitals, long-term care kitchens, food trucks, and high-volume restaurants each have different access points, schedules, and risk profiles. Ask if the company has handled your specific setup before.
6. Verifiable reviews.
Look for a real, sustained review history – not just a handful of five-star reviews all posted the same week.

What Hood Cleaning Costs in Ontario
There’s no honest flat rate for hood cleaning, and any company quoting one without seeing your kitchen is guessing. Cost depends on:
- Hood size and number of exhaust systems
- Duct length and how accessible the rooftop unit is
- Current grease buildup (a first-time deep clean costs more than routine maintenance)
- Kitchen type – restaurant, hospital, food truck, and residential range hood scopes all differ
Because of these variables, a legitimate quote should follow a quick assessment of your kitchen, not a number pulled from a price list. Fast Hood Cleaners provides a free quote within 24 hours after a short assessment, with no hidden or extra charges added afterward.
Who Needs Hood Cleaners?
- Restaurants and quick-service kitchens – the most common and highest cooking-volume category under NFPA 96.
- Hospitals, retirement homes, and long-term care facilities – kitchens that run continuously and require scheduling around resident routines.
- Food trucks – same fire code requirements as a full kitchen, in a much smaller, harder-to-access space.
- Industrial and shelter kitchens – high-volume operations with their own access and safety considerations.
- Homeowners – residential range hoods build up grease that standard household cleaning can’t remove from the ductwork.
Each of these has a different scope, which is why Fast Hood Cleaners runs separate service lines for commercial hood cleaning, healthcare and hospitality kitchens, food trucks, and residential range hoods.

Frequently Asked Questions
How do I know if a hood cleaning company is actually certified?
Ask who trained and certified the technicians, and ask for the name of the standard they work to (it should be NFPA 96). A legitimate company will tell you without hesitating and will confirm it in writing on your invoice or certificate.
Is the cheapest hood cleaning quote usually the best option?
Not if it skips steps. A quote well below others in your area often means the rooftop fan isn’t being cleaned, the ductwork isn’t reached, or you won’t receive inspection documentation – all of which can cost far more later in a failed inspection or a denied insurance claim.
Do hood cleaners work around my kitchen’s operating hours?
Yes, most commercial hood cleaning companies, including Fast Hood Cleaners, schedule around your restaurant’s service hours so cleaning doesn’t interrupt your operations.
What happens if I skip hood cleaning and just rely on my fire suppression system?
A fire suppression system is a backup for when a fire starts – it isn’t a substitute for removing the grease that fuels one. NFPA 96 requires both a maintained suppression system and a regular hood cleaning schedule; relying on suppression alone still leaves a kitchen out of compliance.
Can I use the same hood cleaning company for my restaurant and my food truck?
Yes, as long as the company has documented experience with both. The access points, duct length, and scheduling constraints differ significantly between a fixed kitchen and a food truck, so confirm they’ve handled truck-sized systems specifically.
