Hood cleaning leads: you are not selling a job, you are selling a schedule

The night route: how the work actually gets sold

This is one of the few trades where door-to-door still outperforms advertising, because the buyer is on site and the problem is visible. The approach that works is not a pitch — it is an inspection.

• Arrive between 2 p.m. and 4 p.m., the gap between lunch and dinner service, when a manager can actually talk.
• Ask to look at the hood and the rooftop fan, and take two photos. Grease depth in the duct and on the fan blades is a physical fact, not a sales claim.
• Show the photos and the standard. Explain the cleaning interval expected for their cooking type and volume, and what an inspector looks for.
• Quote a schedule, not a job. A quarterly price with a fixed month is easier to approve than a one-time number, and it is what makes the account recur.

What a complete cleaning includes, and what shortcuts look like

Price differences in this trade usually reflect scope differences that the customer cannot see. A complete service covers the hood and filters, the plenum, the full length of horizontal and vertical duct, the fan housing and blades, and grease containment on the roof, with the system returned to operation and tested.

Shortcuts are common and identifiable: cleaning only the hood surface and filters, skipping the duct entirely, not removing the fan, leaving the roof greasy, and failing to install or use access panels where the duct cannot otherwise be reached. Access panels matter — a duct run with no access is a duct that has never been cleaned, and adding panels is both a code-driven necessity and a legitimate upsell.

Two documents separate a professional operation from a truck with a pressure washer: a service report with before-and-after photographs of each section, and a certificate and sticker stating the date, the scope, what could not be cleaned and why. That last field is what protects you when an inspector finds an inaccessible section, and it is the reason to write it rather than avoid it.

The math: pricing by system, not by hour

Estimating by hood length alone is the most common pricing error. The cost drivers are the duct run, the roof access and the degree of accumulation.

• Number of hoods and filters, and cooking type beneath each.
• Duct length and configuration, including horizontal runs and turns, plus whether access panels exist.
• Roof access and fan type: ladder, hatch, distance from the truck, and whether the fan hinges.
• Accumulation level, which decides whether this is a maintenance clean or a restoration of a neglected system.
• Crew size and hours, at night, with the cleanup and protection time included.

A worked example. A restaurant with two hoods, 40 feet of duct with three turns, hinged fan and quarterly service. Crew of two, four hours on site including setup and protection. Fully burdened crew cost $86 per hour for two: $688. Chemicals, filters and supplies: $70. Travel and disposal: $60. Direct cost $818. Priced at $650, this account loses money.

Priced correctly at $1,150 quarterly, the same account produces $332 of contribution per visit, or $1,328 a year. The lesson is not that the price should be high — it is that the first restaurant cleaned as a favor at a friend's price becomes the reference price for that operator's entire network of restaurant friends.

Route density is the profit lever

Night work with a two-person crew has a hard ceiling: a crew can do two, sometimes three systems in a night. What decides profitability is how much of that night is spent driving.

• Cluster by area and by night. A downtown block with six restaurants can fill three nights a quarter with almost no windshield time.
• Align frequencies within a cluster. Getting neighboring accounts onto the same quarterly month is worth more than a small price increase.
• Sell the neighbors while you are parked. The most efficient sales call in this business happens at 3 p.m. two doors down from tonight's job.

Safety, insurance and the risks that end companies

Three risks in this trade are severe enough to be treated as operating disciplines rather than paperwork.

Fire. Grease fires during or after cleaning, from residual chemical contact with hot surfaces or from reactivating a system before it is dry. Procedures and equipment must be followed exactly, and the crew must know the shutdown sequence.

Water and roof damage. Water travelling into the building through the duct, or grease and washwater discharging onto a roof or into a storm drain. Containment is not optional, and improper discharge carries environmental liability in most jurisdictions.

Slips, ladders and confined spaces. Night work, wet surfaces, roof edges and duct interiors are the injury profile of this business.

Insurance requirements and applicable standards vary and must be verified locally — and, commercially, the certificate of insurance is often what a property manager asks for before anything else.

A year in numbers

A two-truck operation moving from one-off jobs to contracted routes, with pricing rebuilt around system complexity instead of hood length.

• Q1: 61 jobs, 44 different customers, average $610. Revenue $37,210. Only 12 accounts on a schedule.
• Q2: pricing rebuilt; 14 unprofitable accounts repriced, 3 lost. 58 jobs, average $840. Revenue $48,720.
• Q3: suppression company partnership begins; night routes clustered by district. 71 jobs, average $870. Revenue $61,770.
• Q4: 79 jobs, 58 of them on contracted schedules. Revenue $69,300.

Year totals: $217,000, with contracted accounts rising from 12 to 58. The margin improvement came from two decisions with no new marketing spend: repricing by system complexity and clustering routes by district.

Worth noting what happened with the three accounts lost to repricing: all three were the smallest and furthest away, and their removal freed an entire night per quarter — which was immediately filled by two clustered accounts at full price.

The services that grow an account without new customers

Because acquisition in this trade is slow and relationship-driven, the fastest growth comes from selling more to kitchens you already visit at night. Five adjacent services fit naturally and require little additional equipment:

• Filter exchange programs. Swapping filters on a set interval, with clean ones delivered and dirty ones taken away, converts a variable task into a monthly line item.
• Rooftop grease containment. Absorbent systems that keep grease off the membrane, replaced on schedule — genuinely useful to the property owner and easy to justify after one photo of a stained roof.
• Access panel installation. Required to clean sections that are otherwise unreachable, and a legitimate one-time sale that also improves the quality of every future service.
• Hinge kits for fans. They make every subsequent cleaning faster and safer, which benefits both parties — one of the few upsells that reduces your own cost.
• Kitchen deep cleaning and drain maintenance. Already being on site at night, with a crew and equipment, makes this an efficient extension for operators who struggle to get it done.

The right moment to offer all five is the same: at the end of a completed service, with the photos on the phone, when the operator has just seen what the system looked like before. Selling these by phone a month later converts a fraction as well.

Staffing a night operation

The hardest part of this business is not selling: it is keeping crews. Night hours, dirty work and physical demand produce turnover, and every departure costs training and, occasionally, an account that liked the previous technician.

Four practices make a measurable difference:

Fixed schedules. Predictable nights beat higher pay for most crew members. A rotating, unpredictable calendar is the single biggest driver of turnover in night service work.

Pay for the route, not the hour, once the crew is experienced. A team that finishes three systems well in seven hours should not earn less than one that takes nine — with quality verified by the photo documentation that already exists.

Equipment that reduces physical strain. Better hoses, lighter pressure equipment, proper lighting and roof access gear. It shows up as fewer injuries and longer tenure.

Progression. Technician, lead technician, route supervisor. In a trade where most competitors offer none of that, a visible ladder keeps the people who already know your accounts — which is worth more than any recruiting effort.

Six mistakes that cost hood cleaners money

• Pricing by hood length. It ignores the duct, the roof and the accumulation, which is where the labor lives.
• Selling a job instead of a schedule. One-off work has no compounding value and no route density.
• Skipping documentation. The report, the photos and the certificate are what the operator needs for the inspector and the carrier.
• Leaving the roof greasy. It causes damage claims, and it is the first thing a competitor photographs.
• Ignoring inaccessible duct sections. Note them, quote access panels, and put it in writing.
• Taking the cheap first job to get in the door. That price follows you through the operator's entire network.

Five numbers to track

Five metrics run this business. Annual revenue per account, sorted, which reveals who is actually carrying the company. Percentage of revenue under a fixed schedule, the measure of predictability. Systems cleaned per crew-night, which is the route-density number. Contribution per visit by account, so unprofitable customers are visible before renewal. And schedule adherence — the percentage of accounts serviced in the month they were due — because in a business where the customer's insurance and fire inspection depend on the interval, being late is how accounts are lost.

Frequently asked questions

How should hood cleaning be priced?

By system complexity, not by hood length, which is the most common pricing error in the trade. The cost drivers are the number of hoods and filters with the cooking type beneath each, the duct length and configuration including horizontal runs, turns and whether access panels exist, the roof access and fan type — ladder, hatch, distance from the truck, and whether the fan hinges — the accumulation level, which decides between a maintenance clean and a restoration, and crew size and hours at night with setup, protection and cleanup included. A worked example: two hoods, 40 feet of duct with three turns and a hinged fan, a crew of two for four hours at a burdened cost of $86 per hour, plus $70 in supplies and $60 in travel and disposal, costs $818 to serve. At $650 that account loses money on every visit.

Where do hood cleaning accounts come from?

Six channels, and the strongest are relationships rather than advertising. Fire inspections and violations create deadlines, so those calls close fast and at full price because the alternative is a closed kitchen. Insurance carriers frequently require documented cleaning at defined intervals, and the certificate you leave behind is what the operator sends them. Fire suppression companies are the single best referral channel, since they are already in the kitchen semiannually and do not clean hoods. Restaurant equipment suppliers and repair technicians see the state of exhaust systems constantly. Property managers of food-court and multi-tenant buildings offer one relationship covering many kitchens and a shared rooftop system. And new openings need a schedule from day one, with whoever is there at opening usually keeping the account for years.

What should a complete hood cleaning include?

The hood and filters, the plenum, the full length of horizontal and vertical duct, the fan housing and blades, and grease containment on the roof, with the system returned to operation and tested. Shortcuts are common and identifiable: cleaning only the hood surface and filters, skipping the duct entirely, not removing the fan, leaving the roof greasy, and failing to install or use access panels where the duct cannot otherwise be reached — a duct run with no access is a duct that has never been cleaned. Two documents separate a professional operation from a truck with a pressure washer: a service report with before-and-after photographs of each section, and a certificate and sticker stating the date, the scope and what could not be cleaned and why. That last field is what protects you when an inspector finds an inaccessible section.

How often do restaurant hoods need to be cleaned?

The interval is driven by cooking volume and type, and the applicable standard, inspection expectations and local fire code requirements must be verified with the authority having jurisdiction. In practice, high-volume solid fuel and wok cooking require far more frequent service than a low-volume operation, and insurance carriers often specify intervals of their own. Commercially, the interval is the product: a restaurant cleaned quarterly at $650 produces $2,600 a year, and ten such accounts are $26,000 of predictable annual revenue before a single new customer is added. That is why the sale should always be a schedule with a fixed month rather than a one-time job — it is easier for a manager to approve, and it is what turns a service call into an account that renews on its own.

How do you grow a hood cleaning company without adding customers?

By selling adjacent services to kitchens you already visit. Five fit naturally and need little extra equipment: filter exchange programs, which convert a variable task into a monthly line item; rooftop grease containment, easy to justify after one photo of a stained roof membrane; access panel installation, required to reach sections that are otherwise uncleanable; hinge kits for fans, which make every future cleaning faster and safer and are one of the few upsells that lower your own cost; and kitchen deep cleaning or drain maintenance, efficient to add when the crew is already on site at night. The right moment to offer all five is at the end of a completed service, with the before-and-after photos on the phone — adding a recommended-but-not-included line to the service report converts far better than a phone call a month later.
