Commercial Kitchen Exhaust Hood Cleaning Route Business
Fire codes force every commercial kitchen to have its grease ducts professionally cleaned on a schedule, which turns a filthy job into a recurring, inspection-driven route.
The problem
Grease builds up inside kitchen hoods, filters, ductwork, and exhaust fans every service, and it is one of the most common causes of restaurant fires. Codes and insurers require it to be cleaned to bare metal on a frequency set by cooking volume, and the fire marshal or insurer wants a dated certificate and a service sticker to prove it. Restaurant owners know they need it done, but the market is full of operators who clean only what is visible, skip the horizontal duct runs and the rooftop fan, and leave a sticker anyway. The owner finds out when the inspector opens an access panel, or worse, after a duct fire.
Why now
Two pressures are tightening at once. Insurers have become far stricter about documented kitchen exhaust maintenance after years of costly restaurant fire claims, and many now ask for before-and-after photographs, not just a sticker. At the same time restaurant counts have recovered and the number of ghost kitchens, food halls, and commissary kitchens has grown, each with hoods that need servicing. The work itself has not changed, which is exactly why a well-run, well-documented operator can take share from the long tail of cash-only crews.
Who pays
Independent restaurants, restaurant groups, hotel kitchens, school and hospital cafeterias, food halls, ghost kitchens, and commissary kitchens. Secondary buyers are property managers and facility managers responsible for several kitchens, and insurers or brokers who want a reliable vendor to refer.
How it makes money
Per-service pricing that typically ranges from a few hundred dollars for a small single hood to several thousand for a large multi-hood kitchen, billed at a frequency set by cooking volume, commonly quarterly or semi-annually, with monthly service for high-volume or solid-fuel kitchens. Add-ons that raise ticket size include exhaust fan hinge kits, access panel installation, filter exchange programs, fan belt replacement, and rooftop grease containment.
Market & demand
Order-of-magnitude: there are well over a million commercial kitchens across the United States, United Kingdom, Canada, and Australia, and nearly all with a commercial hood are required to have it serviced at least annually and often quarterly. A two-crew operator with a few hundred recurring accounts in one metro runs a solid seven-figure business, which is a small fraction of any single city's kitchens.
Insurers and fire authorities are moving from stickers to evidence, with photo documentation and third-party certified technicians increasingly expected. Franchised competitors have entered the space, which raises the professional bar and validates pricing. Kitchen formats are multiplying through ghost kitchens and food halls, adding hoods even where dining rooms are not growing.

SWOT
Strengths
- Code-mandated recurring demand that does not depend on marketing to persuade
- Unpleasant, technical work that deters casual competitors
- Accounts renew by default once you are on the schedule
Weaknesses
- Overnight work, grease, heights, and chemicals make crews hard to hire and keep
- Wastewater handling and rooftop work add compliance and equipment cost
- Restaurant customers churn when they close, which many do
Opportunities
- Broker and insurer referral relationships built on documentation quality
- Multi-site restaurant groups and facility managers that consolidate vendors
- Adjacent recurring services such as grease trap pumping coordination, filter exchange, and fire suppression partner referrals
Threats
- Franchise brands with national accounts undercutting on multi-site contracts
- Low-price cash operators who compete on the sticker rather than the work
- Liability exposure if a kitchen you serviced has a fire
Competition & the gap
Franchise operators such as HOODZ, regional specialists such as Nelbud Services, fire protection companies that bundle hood cleaning as a sideline, and a long tail of small independent crews, many of whom are not certified.
The wedge: The durable position is being the operator whose documentation stands up to an insurer: certified technicians, before-and-after photos of every section including horizontal runs and the fan, a dated report, and a reminder system that means no customer ever falls out of compliance. That standard is easy to describe and rare in practice, because it takes longer per job and needs systems most small crews do not run.
Go-to-market
Go where the trigger is: fire inspection failures, insurance renewals, and new openings. Build referral relationships with fire suppression service companies, commercial insurance brokers, restaurant equipment dealers, and commercial property managers. Walk restaurant strips in daylight with a sample report and offer a free inspection with photographs of what is actually inside their duct.
First 10 customers: Offer ten independent restaurants a free inspection with borescope or phone photographs of their duct interior and a written compliance assessment. Most will not have seen inside their own ductwork and will book once they do. Price the first jobs competitively, deliver an exceptional photo report, and ask each owner to introduce you to the landlord or group operator.
How to set it up
- 1Train and certify technicians through IKECA or the relevant national standard such as BESA TR19 Grease
- 2Buy the core kit: hot water pressure washer, degreasers, scrapers, tarps, containment systems, ladders, and a vehicle or trailer
- 3Set up wastewater capture and disposal that complies with local rules before the first job
- 4Secure general liability, workers compensation, and ideally pollution liability cover
- 5Build a report template with dated before-and-after photographs for hood, filters, duct runs, and fan
- 6Use field service software to schedule recurring frequencies and send automatic renewal reminders
- 7Sign referral agreements with two fire suppression companies and three commercial insurance brokers
How to validate it
Inspection-to-booking conversion above half, accounts rebooking on schedule without chasing, brokers and property managers sending referrals, and multi-site groups consolidating their locations with you.
Key risks
- You carry real liability if a kitchen you serviced has a fire, so documentation of exactly what was cleaned and what was inaccessible is your main defence
- Rooftop fan work, ladders, caustic chemicals, and slippery surfaces create genuine injury risk for crews
- Improper wastewater disposal can bring environmental fines, so treat containment and disposal as a core process
- Night shifts and grease make crew retention difficult, and turnover degrades quality
- Restaurant closures create steady account churn, so sales must continue even when the route is full
Your moats
- A recurring route of accounts on code-mandated schedules
- Certification and documentation quality that insurers and brokers trust
- Referral relationships with suppression companies, brokers, and property managers
- Route density in one metro, which lowers cost per job below scattered competitors
