How to Start a Hood Cleaning Business From Scratch

Starting a hood cleaning business requires relatively low startup capital, specialized but learnable skills, and a steady market of restaurants and commercial kitchens that need regular exhaust system cleaning to meet fire codes. Initial investment typically ranges from $10,000 to $50,000 depending on how much equipment you buy upfront versus lease. Here’s what it takes to get from idea to first paying client.

Why the Demand Is Consistent

Every commercial kitchen with a cooking exhaust system must have it cleaned on a regular schedule. NFPA 96, the national fire code standard for ventilation control and fire protection of commercial cooking operations, requires periodic cleaning based on cooking volume. High-volume kitchens like 24-hour diners and fast-food restaurants need quarterly cleanings. Moderate-volume restaurants typically need semi-annual service. This isn’t optional: fire marshals inspect for compliance, and restaurants risk fines, failed inspections, or even forced closures if their systems aren’t maintained.

That regulatory pressure creates a recurring revenue model. Once you land a restaurant client, you’re likely cleaning their system two to four times per year, every year, as long as you do good work.

Equipment You’ll Need

The core toolkit for kitchen exhaust cleaning is straightforward but specialized. You’ll need a hot-water pressure washer (the single most important piece of equipment), a wet/dry vacuum for collecting wastewater, chemical degreasers formulated for grease-laden exhaust systems, and specialized hand tools like scrapers and brushes for areas the pressure washer can’t fully reach.

Beyond cleaning tools, you need containment supplies. Heavy-duty plastic sheeting protects the kitchen’s floors, walls, and appliances from the water and degreaser runoff during cleaning. Personal protective equipment, including chemical-resistant gloves, eye protection, and non-slip boots, is essential since you’re working with caustic chemicals in wet, greasy environments.

You’ll also need a reliable vehicle, ideally a van or enclosed trailer, to haul your equipment to job sites. Many operators start with a used cargo van and upgrade as revenue grows. Budget for hoses, fittings, extension cords, drop lights for working inside dark ductwork, and a supply of before-and-after photo equipment (even a smartphone) since documentation is part of the service you’ll provide to clients for their fire marshal records.

Startup Costs

Total startup costs typically fall between $10,000 and $50,000. The low end assumes you’re buying a quality used pressure washer, minimal chemical inventory, and using a vehicle you already own. The higher end covers a new commercial-grade hot-water pressure washer (which alone can run $3,000 to $8,000), a dedicated work vehicle, full insurance coverage, and professional certifications.

Don’t overlook recurring costs: chemical degreasers, fuel, vehicle maintenance, insurance premiums, and marketing. Many new operators underestimate how much degreaser they’ll go through in the first few months while dialing in their process.

Licensing and Legal Setup

You’ll need a general business license in most jurisdictions, and you should register your business as an LLC or other formal entity to separate personal and business liability. This matters more in hood cleaning than in many service businesses because you’re working around fire suppression systems, grease-laden ductwork, and commercial kitchens, all of which carry real damage risk.

Licensing requirements for kitchen exhaust cleaning vary significantly by location. Some cities and counties require specific permits or fire department credentials to perform this work. Others have no special requirements beyond a standard business license. Contact your local fire marshal’s office and your city or county business licensing department before you start marketing. They’ll tell you exactly what credentials you need in your area.

Professional Certifications

While not legally required everywhere, professional certification dramatically boosts your credibility and can be the deciding factor when a restaurant chooses between you and a competitor. The International Kitchen Exhaust Cleaning Association (IKECA) offers the industry’s most recognized credentials:

  • Certified Exhaust Cleaning Technician (CECT): Designed for crew leaders who run cleaning jobs. Requires passing a 100-question exam with a score of 70% or higher. Valid for two years.
  • Certified Exhaust Cleaning Specialist (CECS): Geared toward business owners and operations managers. Also a 100-question exam requiring 70% to pass. Valid for one year and must be renewed annually.
  • Certified Exhaust System Inspector (CESI): Focused on codes and standards, useful if you want to offer inspection services alongside cleaning. Requires a 72% passing score. Valid for two years.

IKECA also offers a Professional Exhaust Cleaning Technician (PECT) designation, which serves as a stepping stone before pursuing full certification. If you’re brand new to the trade, starting with the PECT track helps you learn the technical fundamentals before sitting for the certification exams.

Many restaurant chains and property management companies specifically require IKECA certification from their cleaning vendors. Getting certified early positions you to win these higher-value contracts.

Insurance Coverage

Insurance isn’t optional in this business. You’re working with high-pressure water, caustic chemicals, and fire suppression systems inside someone else’s commercial property. One mistake, like accidentally triggering a suppression system or causing water damage, can result in thousands of dollars in claims.

At minimum, you need general liability insurance, which covers damage to a client’s property during your work. If you accidentally damage flooring, break equipment, or cause water damage, your policy covers the associated costs. Commercial property insurance protects your own equipment, tools, and vehicle contents. Many operators bundle these into a Business Owner’s Policy (BOP), which combines general liability and commercial property coverage into a single, often cheaper package.

If you hire employees, you’ll also need workers’ compensation insurance, which is legally required in most states. Your premiums will depend on your number of employees, payroll, location, claims history, and the coverage limits you choose. Get quotes from insurers experienced with cleaning or trades businesses, since they’ll better understand your risk profile.

Setting Your Prices

Commercial kitchen hood cleaning, the bread and butter of this business, typically runs between $800 and $1,500 per session for standard multi-hood systems with integrated ductwork. Heavy-duty jobs requiring chemical cleaning of larger or more complex systems can reach $1,000 to $2,500. Labor rates in the industry generally range from $50 to $100 per hour when pricing is calculated on a time basis.

Several factors affect what you can charge. Location matters: jobs in urban metro areas typically command $400 to $1,500, while suburban jobs fall in the $300 to $900 range and rural areas run $250 to $800. Difficult access, such as high ceilings, rooftop units, or tight spaces, justifies adding $100 to $400 to your base price.

Some operators also take on residential hood cleaning, which pays less per job ($200 to $700 depending on the hood type) but can fill gaps in your schedule. The real money, though, is in recurring commercial contracts. A single restaurant needing quarterly cleaning at $1,000 per visit represents $4,000 in annual revenue from one client. Build a roster of 30 to 50 commercial accounts and you have a six-figure business.

Finding Your First Clients

Your initial clients will likely come from direct outreach. Visit restaurants, cafeterias, hotels, hospitals, and any facility with a commercial kitchen. Talk to the manager or owner, ask when their system was last cleaned, and offer a free inspection. Many smaller restaurants are either overdue for cleaning or unhappy with their current provider’s reliability.

Build a simple website that emphasizes your certification, insurance, and before-and-after photos. When restaurant owners or managers search for hood cleaning services in your area, you want to show up. Claim your Google Business Profile immediately and ask satisfied clients to leave reviews. In a local service business, Google reviews are one of your most powerful marketing tools.

Networking with fire marshals, health inspectors, and commercial kitchen equipment suppliers can also generate referrals. These professionals regularly encounter kitchens that need cleaning and appreciate having a reliable vendor to recommend.

Running the Jobs

A typical hood cleaning job follows a predictable process. You arrive after the kitchen closes for the night, usually late evening or early morning. You lay down plastic sheeting to protect the kitchen surfaces, disconnect and soak the hood filters in degreaser, then use the hot-water pressure washer to clean the interior of the hood, the ductwork (as far as you can access), and the exhaust fan on the roof. You scrape and hand-clean areas that need extra attention, vacuum up all wastewater, and leave the kitchen clean and dry.

Documentation is critical. Photograph the system before and after cleaning, noting the condition of the ductwork, any damage or excessive grease buildup, and the areas you serviced. Provide a written report to the client. Restaurants keep these reports on file for fire marshal inspections, and thorough documentation sets you apart from fly-by-night competitors who show up, spray some water, and leave.

Most jobs take two to four hours for a single crew on a standard restaurant system. Larger facilities with multiple hoods or extensive ductwork can take a full shift. As you gain experience, you’ll get faster and more efficient, which directly improves your earnings per hour.

Scaling Beyond Solo Work

Many hood cleaning businesses start as a one-person operation, with the owner doing every job personally. This works well initially since it keeps overhead low and lets you learn the trade hands-on. But the business model scales nicely once you’re ready to hire.

Your first hire should be a helper who can assist with setup, containment, and cleanup while you handle the actual cleaning. As demand grows, you can train crew leaders, invest in a second set of equipment, and run multiple crews on the same night. Each crew that’s out working while you’re managing the business multiplies your revenue without multiplying your personal hours.

The key to scaling is systems: standardized checklists for every job, consistent documentation, reliable scheduling software, and clear training procedures so your crews deliver the same quality you would. Restaurants value consistency above almost everything else in a cleaning vendor.
