Commercial Kitchen Hood Cleaning Cost Guide: Complete Pricing Breakdown for Restaurants (2026)

What Restaurants Actually Pay for Hood Cleaning — and Why Prices Vary So Much

If you've called three kitchen exhaust cleaning companies and received quotes ranging from $400 to $2,500 for the same restaurant, you're not alone. Commercial hood cleaning cost varies dramatically based on factors most restaurant owners don't discover until they're comparing bids — and the cheapest quote often costs more in the long run.

This guide breaks down exactly what drives commercial kitchen exhaust cleaning pricing, what a fair price looks like for your restaurant type, and how to evaluate quotes beyond the bottom-line number.

Average Commercial Kitchen Hood Cleaning Costs by Restaurant Type

Fast Food / Quick Service Restaurant

• Typical system: 1-2 hoods, 15-30 linear feet of duct, 1 exhaust fan
• Cleaning frequency: Every 3-6 months (per NFPA 96, depending on cooking volume and fuel type)
• Per-service cost: $300-700
• Annual cost: $1,200-2,800 (quarterly service)

Full-Service Restaurant

• Typical system: 2-4 hoods, 30-60 linear feet of duct, 1-2 exhaust fans
• Cleaning frequency: Every 3-6 months for solid fuel, every 6-12 months for gas/electric
• Per-service cost: $600-1,800
• Annual cost: $1,800-7,200

Hotel / Banquet Kitchen

• Typical system: 4-8 hoods across multiple stations, 60-150+ linear feet of duct, multiple fans, often includes vertical risers through multiple floors
• Cleaning frequency: Quarterly to semi-annual for high-volume stations
• Per-service cost: $1,500-5,000+
• Annual cost: $6,000-20,000+

High-Volume / 24-Hour / Solid Fuel Restaurant

• Typical system: Wok stations, charbroilers, wood-fired ovens, or solid fuel grills produce dramatically more grease
• Cleaning frequency: Monthly to quarterly (NFPA 96 requires more frequent inspection and cleaning for solid fuel)
• Per-service cost: $500-1,500 per service (higher due to frequency and grease volume)
• Annual cost: $6,000-18,000

The 7 Factors That Determine Your Kitchen Exhaust Cleaning Price

1. Linear Feet of Ductwork

This is the primary pricing driver. Most contractors charge $12-25 per linear foot for accessible horizontal duct and $18-35 per linear foot for vertical riser duct. A restaurant with 80 feet of duct pays more than one with 20 feet — straightforward math. What's less obvious: duct that runs through walls, floors, or inaccessible ceiling spaces costs more because the contractor may need to install additional access doors.

2. Number of Hoods and Fans

Each hood requires interior and exterior cleaning plus filter removal and reinstallation. Each exhaust fan requires disassembly, cleaning of the fan blades, housing, and hinge kit, plus reassembly. These are typically priced as flat per-unit charges: $75-150 per hood and $100-250 per fan.

3. Type of Cooking — and Type of Fuel

This is the factor most restaurant owners overlook. A gas charbroiler produces significantly more airborne grease than an electric convection oven. Wood-fired and solid fuel cooking produce the heaviest grease loads and may require chemical degreasing in addition to mechanical brushing — adding 20-40% to the service cost. NFPA 96 classifies systems by fuel type and cooking volume, with more stringent (and frequent) requirements for heavier grease loads.

4. Access Difficulty

Duct access doors every 12 feet of horizontal duct and at each change of direction are required by code — but many older restaurants don't have them. If the contractor needs to install new access doors (cutting into duct, fabricating door panels, sealing with fire-rated gasket), expect $200-500 per door. A restaurant that's never had proper access doors installed will pay significantly more for its first professional cleaning — but subsequent cleanings will be faster and cheaper.

5. Geographic Market

Hood cleaning costs 30-50% more in major metropolitan areas (New York, San Francisco, Los Angeles, Chicago) than in smaller markets, driven by higher labor costs, stricter local fire codes, and higher insurance requirements. Urban restaurants in older buildings also tend to have more challenging duct configurations.

6. Documentation Requirements

Basic service includes a cleaning certificate. Comprehensive documentation — before/after photos of every duct section, exhaust fan internal photos, grease measurement readings, and a detailed compliance report suitable for insurance underwriters and fire marshal review — adds $100-300 to the service cost. For chain restaurants and franchise locations with corporate compliance requirements, this level of documentation is often mandatory, not optional.

7. After-Hours Service

Most restaurant hood cleaning happens at night, after the kitchen closes. This is standard and usually built into the pricing. However, if your restaurant requires weekend or holiday service, expect a 15-25% premium. If you need same-day or emergency service (fire marshal citation, insurance deadline), expect 25-50% premium — and limited contractor availability.

The Hidden Cost of Cheap Hood Cleaning

A $350 hood cleaning that misses 40% of the duct interior is not a bargain — it's a fire waiting to happen. Inadequately cleaned kitchen exhaust systems are the leading cause of restaurant fires, and insurance adjusters know exactly what to look for after a fire: grease accumulation thickness, access door spacing, and documentation quality.

When the fire investigator determines the exhaust system wasn't cleaned to NFPA 96 standards, the insurance claim may be denied. The restaurant owner who saved $300 per cleaning faces a $50,000-500,000 uninsured fire loss — plus business interruption, reputation damage, and potential lawsuits from injured patrons or employees. The $300 savings evaporates about 167 times over.

How to Evaluate Hood Cleaning Quotes

When comparing quotes, ask each contractor to specify:

1. Linear footage measured: If one quote says 40 feet and another says 65 feet for the same system, one of them isn't measuring the full duct run — and that's the one that will leave sections uncleaned.
2. Cleaning method: "We'll brush what we can reach" is not a method. "Mechanical rotary brushing from access point to access point with HEPA vacuum collection per NFPA 96 Section 11" is a method. The difference matters.
3. Access door plan: If your ducts don't have access doors at code-required intervals, does the quote include installing them? A cheap quote that ignores missing access doors is a cheap quote that won't actually clean your entire system.
4. Documentation included: Will you receive before/after photos of every duct section and exhaust fan interior? For insurance and fire marshal purposes, "trust us, we cleaned it" doesn't count.
5. Fan service: Does the price include full exhaust fan disassembly, cleaning, and reassembly — or just the ductwork? Fan cleaning is required by NFPA 96 and should be included in every service.

Reducing Your Long-Term Hood Cleaning Costs

• Install proper access doors now: If your ducts are missing access doors, the one-time cost of installing them ($200-500 each) reduces every future cleaning by making the system fully accessible. Payback is typically within 2-3 cleaning cycles.
• Schedule regular cleanings on a fixed calendar: Contractors offer better rates for scheduled, recurring service than for one-off or emergency calls. A quarterly contract typically costs 10-20% less per service than scheduling each cleaning individually.
• Train kitchen staff on filter maintenance: The single most effective thing your kitchen staff can do is clean hood filters regularly (weekly minimum) and ensure they're properly seated after cleaning. Filters that trap grease before it enters the duct reduce duct cleaning frequency and cost.
• Upgrade to high-efficiency filters: Baffle filters capture 60-70% of airborne grease. High-efficiency cartridge-style filters capture 90%+. The filter upgrade pays for itself through reduced duct cleaning frequency and lower per-service cleaning costs.
