You call three companies for a hood cleaning quote and get three very different numbers. One says $450. One says $900. One won't quote at all until they see photos. You are left wondering which one is honest, which one is padding, and which one is about to clean the visible hood face and call it a day.
Commercial hood cleaning cost is one of the most-searched questions in restaurant maintenance, and for good reason: the spread between quotes is wide, the line items are unfamiliar, and the cheapest number is often the most expensive mistake. Nationally, a single service runs roughly $400 to $1,500 — but that range is so broad that it is almost useless until you understand what moves your kitchen toward one end or the other.
This guide breaks down the national price bands, the difference between hourly and flat-rate pricing, the five factors that actually drive your number, the red flag in a too-cheap quote, and what hood cleaning costs specifically in the DC, Maryland, and Virginia market.
National Hood Cleaning Cost Ranges
As a baseline, here is what restaurant hood cleaning price looks like across the country, scaled to the number of hoods in the system:
- Single hood: roughly $400 to $600 per service.
- 3 to 5 hoods: roughly $600 to $1,000 per service.
- 6 to 10 hoods: roughly $1,000 to $1,500 per service.
- 10+ hoods: custom pricing — hotel banquet kitchens, hospital cafeterias, and large multi-line operations are quoted on system specifics, not a table.
So the average cost of hood cleaning for most independent restaurants lands somewhere in the $400 to $1,500 window per visit. The figure that actually matters for budgeting, though, is annual cost — and that depends on frequency. A quarterly kitchen at $900 a visit spends $3,600 a year; a monthly charbroil operation at $1,200 a visit spends over $14,000. (Not sure how often you are due? Start with how often commercial hoods should be cleaned.)
Hourly vs. Flat-Rate Pricing
How much does kitchen exhaust cleaning cost when it is billed by the hour rather than per system? Two-technician crews commonly run $100 or more per hour nationally, and a typical single-hood job runs a few hours including setup, cleaning to bare metal, and documentation.
Most reputable companies quote flat-rate by system rather than hourly, because flat-rate protects you: the price is fixed before the truck arrives, and the crew has no incentive to stretch the clock. Hourly pricing can be fair for unusual one-off jobs, but for routine recurring service, a flat per-visit number you can budget around is almost always the better arrangement. Either way, get the scope in writing — the price only means something when you know exactly what it buys.
The Five Things That Move Your Price
Two restaurants on the same block can get quotes that differ by hundreds of dollars. Five factors explain almost all of it:
1. Number of hoods
The single biggest driver. Each hood adds setup, cleaning labor, and documentation. This is why the national bands scale by hood count.
2. System complexity
A short, straight duct run to a single rooftop fan is simple. Branching ducts, multiple fans, long horizontal runs, and tight bends all add labor and access time. Every bend in a duct is another grease shelf to scrape.
3. Grease buildup
A system cleaned on schedule comes off fast. A neglected system with months of carbonized grease takes scraping, soaking, and far more labor — which is why deferring cleanings to save money usually makes the next visit cost more.
4. Access difficulty
A ground-floor kitchen with an easy rooftop fan is cheap to reach. A fifth-floor restaurant in a high-rise, a multi-story building with shared roof access, or a system with no existing clean-out panels all add time and sometimes equipment.
5. Location and timing
Regional labor costs vary, and most kitchens are cleaned overnight or after close. Weekend, holiday, and emergency service costs more than mid-week scheduled work.
What affects your price — a quick checklist to have ready before you call:
- How many hoods, and how many separate exhaust fans?
- What do you cook — charbroil, wok, fryers, solid fuel, or standard range?
- Where is the fan — ground-accessible roof, multi-story, or hard to reach?
- Are there existing duct access panels, or do they need to be cut?
- How long since the last full cleaning to bare metal?
Why a Suspiciously Cheap Quote Is a Risk
When one quote comes in far below the others, it is rarely a deal. It usually signals one of two things, and both cost you later.
The first is a canopy-only "cleaning" — wiping the visible hood face and the filters while leaving the plenum, duct run, and rooftop fan untouched. It looks clean from the dining room and fails the moment a fire marshal pulls a filter or opens an access panel. The grease that actually fuels a hood fire lives in the parts a canopy-only job skips.
The second is an uninsured operator. Hood cleaning involves working on rooftops, around gas and electrical, and with caustic degreasers. If an uninsured crew is hurt on your roof or damages your fan, the liability can land on you. A legitimate company carries general liability and workers' comp and will show you the certificates without being chased.
A compliant cleaning covers the whole system from hood interior to rooftop discharge, with before-and-after photos and a certificate your AHJ will accept. If a quote is well below market, the right move is not to celebrate — it is to ask exactly what scope that number buys. The cheap quote is often the most expensive once the skipped sections surface at inspection.
What Hood Cleaning Costs in the DC, Maryland, and Virginia Market
The DMV runs slightly above the national baseline — overnight-priced labor, dense urban access, high-rise and historic buildings, and AHJs that expect thorough documentation all nudge the local band up. Reasonable starting points for the DC, Maryland, and Virginia market:
- Single-hood, standard access: roughly $400 to $700 per visit.
- Multi-hood line, moderate volume, standard access: roughly $700 to $1,500 per visit — where most DMV independent restaurants land.
- High-volume (24-hour, heavy charbroil, wok) or difficult access: upper end and beyond, often on monthly cycles.
- Hotel, hospital, and institutional kitchens: custom, driven by scale and access complexity.
These are budgeting starting points, not quotes. A fifth-floor Tysons kitchen with shared roof access and a Georgetown rowhouse with a twisting duct run can price very differently for the same hood count.
How to Get an Exact Number
The only way to know your real commercial hood cleaning cost is a look at your actual system. Two fast paths get you an exact figure:
- Photo quote. Send pictures of your hood, filters, and rooftop fan and we can return a firm number for most standard kitchens, fast.
- On-site assessment. For larger or complex systems, a short walk-through prices the job precisely and confirms the right cleaning frequency at the same time.
Frequently Asked Questions
How much does commercial hood cleaning cost on average?
Nationally, commercial hood cleaning runs roughly $400 to $1,500 per service. A single hood is about $400 to $600, three to five hoods about $600 to $1,000, and six to ten hoods about $1,000 to $1,500. Systems with more than ten hoods are quoted custom based on the specific layout and access.
Why are some hood cleaning quotes so much cheaper?
A quote far below the others usually means a canopy-only job — wiping the visible hood and filters while skipping the plenum, duct, and rooftop fan — or an uninsured operator. Both leave you exposed: the cheap job often fails a fire-marshal inspection, and an uninsured crew can shift liability onto you. Always confirm the full scope and proof of insurance in writing.
Is hood cleaning billed hourly or flat-rate?
Most reputable companies quote flat-rate per system, which fixes the price before work begins. When billed hourly, two-technician crews commonly run $100 or more per hour nationally. For recurring service, a flat per-visit price you can budget around is usually the better arrangement.
What does hood cleaning cost in the DMV?
In the DC, Maryland, and Virginia market, single-hood kitchens with standard access typically start around $400 to $700 per visit, and multi-hood lines commonly run $700 to $1,500. High-volume kitchens, difficult roof access, and institutional systems run higher. A photo or on-site quote gives an exact figure.
The Bottom Line
Commercial hood cleaning cost is a range until someone looks at your system — but you now know the bands, the five drivers, and the red flag that separates a real quote from one that skips the parts that matter. Budget by annual cost, not just per visit, and treat a suspiciously low number as a question, not a bargain.
