Commercial Kitchen Hood Cleaning Costs: Complete Pricing Guide 2026
If you own or manage a commercial kitchen, hood cleaning is not optional — it is a fire code requirement under NFPA 96. But what should you actually pay? Prices vary widely by region, kitchen type, and cleaning frequency. This guide explains typical costs, what factors affect pricing, and how to evaluate quotes from exhaust cleaning contractors.
Average Commercial Hood Cleaning Costs by Kitchen Type
| Kitchen Type | Typical Cost Per Cleaning | Recommended Frequency (NFPA 96) | Annual Budget Range |
|---|---|---|---|
| Small restaurant / cafe (1 hood) | $300-500 | Every 6 months | $600-1,000 |
| Mid-size restaurant (2-3 hoods) | $500-900 | Every 3-6 months | $2,000-3,600 |
| High-volume restaurant / bar & grill | $700-1,200 | Every 3 months | $2,800-4,800 |
| Hotel kitchen (multiple hoods, large system) | $1,500-4,000 | Every 3-6 months | $6,000-16,000 |
| Mall food court (shared system) | $2,000-5,000 | Every 3-6 months | $8,000-20,000 |
| Solid fuel cooking (wood, charcoal) | $500-1,000 | Every 1-3 months | $2,000-12,000 |
Note: Prices are averages for U.S. commercial kitchens. Actual costs vary by location, access difficulty, and contractor experience.
What Affects Commercial Hood Cleaning Cost
1. Scope of Work (Hood, Ducts, Fan)
A complete NFPA 96 cleaning includes the hood canopy, filters, ductwork from hood to exhaust fan, and the roof-top exhaust fan itself. Some quotes only cover the hood and accessible duct — make sure the quote specifies "hood-to-fan" or "complete system" cleaning. A hood-only cleaning may cost less upfront but leaves grease in the ducts, which is both a fire hazard and an NFPA 96 violation.
2. Duct Length and Configuration
Restaurant exhaust ducts range from 5 meters (single-story, direct roof vent) to 30+ meters (multi-story buildings, mall food courts with shared risers). Longer duct runs and complex configurations with multiple bends increase cleaning time and cost. Contractors typically price by the linear foot for duct sections: $8-15 per linear foot for standard cleaning, $15-25 per foot for heavy grease accumulation.
3. Grease Accumulation Level
A kitchen that has been cleaned regularly (every 3-6 months) has lighter grease buildup and is faster to clean. A kitchen that has not been cleaned in 12+ months has heavy, baked-on grease that requires more aggressive cleaning methods — high-pressure hot water, chemical degreasers, and multiple passes. Heavily soiled systems can cost 50-100% more than regularly maintained systems.
4. Access Difficulty
Roof access for exhaust fan cleaning is straightforward in single-story buildings with ladder access. Multi-story buildings may require interior access through ceilings, roof hatches, or even lift equipment. Difficult access adds labor hours and sometimes equipment costs (lifts, additional safety gear).
5. Your Location
Hood cleaning costs are higher in major metropolitan areas (New York, San Francisco, Los Angeles, Chicago) where labor rates and business insurance costs are higher. Rural areas and smaller cities typically see lower pricing. Expect to pay 30-50% more in top-tier metro areas compared to suburban or rural locations.
6. After-Hours Work
Most restaurant hood cleaning is done after the kitchen closes — nights, weekends, or holidays. Contractors typically do not charge extra for standard after-hours work (it is built into their pricing model). However, if you require cleaning during specific hours or on short notice, expect a 25-50% premium.
How to Compare Hood Cleaning Quotes
When evaluating quotes from exhaust cleaning contractors, look beyond the bottom-line price:
- Verify NFPA 96 compliance: The contractor should state in writing that the cleaning will meet NFPA 96 standards. Ask for a sample cleaning report — this is the documentation you show to the fire marshal and your insurance company
- Confirm what is included: Does the quote cover the complete system (hood, duct, fan)? Are filter cleaning/replacement included? What about access panel creation if needed?
- Check for documentation: A professional contractor provides before/after photos with timestamps, a detailed service report, and a sticker on the hood with the cleaning date and next scheduled service. If a contractor cannot provide photo documentation, they cannot prove the work was done
- Verify insurance: Ask for a certificate of insurance naming your restaurant as additional insured. The contractor should carry at least $1 million in general liability
- Avoid the lowest bidder: The cheapest quote often means skipped steps — cleaning only the visible parts of the hood while leaving grease in the ducts where it actually causes fires. A "cheap" cleaning that fails a fire inspection costs far more than a proper cleaning
How Robotic Cleaning Affects Cost and Quality
Contractors using robotic duct cleaning equipment can often deliver better results at competitive prices. Robotic systems with HD cameras provide complete visual documentation of the duct interior before and after cleaning — proof that no grease was left behind. They also access the full duct length from fewer entry points, reducing the number of access panels needed and the associated labor. When evaluating contractors, ask whether they use robotic or manual cleaning methods and request a sample video from a previous job.
Cost Reduction Strategies for Restaurant Owners
- Stick to the recommended schedule: The cheapest way to clean is to never let grease accumulate heavily. Quarterly cleaning costs less per year than semi-annual "deep cleaning" of a heavily soiled system
- Sign an annual contract: Many contractors offer 10-20% discounts for annual service agreements with scheduled cleanings. This also ensures you never miss a required cleaning
- Bundle with other services: If your contractor also offers HVAC duct cleaning, bundling exhaust hood and HVAC cleaning in a single annual contract can save 5-15%
- Proper hood filter maintenance: Clean or replace hood filters regularly. Clogged filters force grease past the filter and into the duct system, accelerating buildup and increasing cleaning costs
