Restaurant exhaust cleaning prices vary because a hood-only visit is not the same service as cleaning the full path through the filters, plenum, ducts, exhaust fan, and rooftop containment. Because a site-specific price depends on the system and requested scope, ask for an itemized quote listing dimensions, system count, access, grease condition, cooking volume, scheduling, exclusions, and documentation.
The useful question is not “What is the average price?” It is “Does this quote cover the same work as the other quote?” Use the framework below to compare scope before comparing totals.
Restaurant Exhaust Cleaning Prices Depend on Scope
A restaurant exhaust quote can cover anything from visible hood degreasing to complete exhaust-system cleaning. Those services require different access, labour, equipment, and time, so one universal price can mislead.
Broad online ranges are non-binding context, not Ontario tariffs or Robinhood Cleaners pricing. The final amount depends on the system, condition, access, service window, and records or related work included. Kitchen exhaust cleaning cost factors are useful only after the scope is defined.
Indicative Market Ranges for Restaurant Exhaust Cleaning
As broad, non-binding market context, a small restaurant exhaust visit may fall around $200 to $500, a medium system around $800 to $1,500, and a large or complex system around $1,500 to $3,000 or more. Very large, heavily soiled, difficult-to-access systems can exceed $3,000, with some complex jobs reaching approximately $6,000.
These ranges are not a quote, Ontario price schedule, or Robinhood Cleaners price list. They describe how the scale of the job commonly changes the budget. A small system may have one short hood, limited ductwork, straightforward access, and moderate grease. A medium system may have a longer hood, more than one duct section, roof access, and regular commercial cooking. A large or complex system may involve multiple hoods, long or difficult duct runs, several access points, heavy buildup, solid-fuel cooking, or a restricted service window.
| Indicative job scale | Typical characteristics | Broad market context |
|---|---|---|
| Small | One short hood, limited ductwork, straightforward access, moderate buildup | About $200–$500 |
| Medium | Longer hood or multiple sections, regular commercial cooking, roof or duct access | About $800–$1,500 |
| Large or complex | Multiple systems, long duct runs, difficult access, heavy grease, or extra labour | About $1,500–$3,000 or more |
| Very large or heavily soiled | Extensive systems, severe buildup, unusual access, or substantial remediation | Approximately $3,000–$6,000 in some cases |
Use the range only to identify an appropriate level of questioning. A $400 hood-only quote and a $1,400 full-system quote may both be reasonable if they cover different components. Ask for the written scope before treating a difference as overcharging or savings.
First Define What the Quote Covers
Ask the provider to identify which components are included, excluded, or available separately.
| Service scope | What it may include | What it does not automatically include |
|---|---|---|
| Hood-only cleaning | Visible hood surfaces, selected filters, and accessible grease removal | Concealed ducts, rooftop fan, plenum, containment, or unrelated equipment |
| Full exhaust-system cleaning | Hood, filters, plenum, accessible ductwork, exhaust fan, access panels, and grease containment | Appliance cleaning, grease-trap service, filter exchange, or belt replacement unless listed |
| Broader commercial kitchen cleaning | Exhaust work plus separately defined appliances, surfaces, floors, exterior areas, or grease-trap work | Any component not named in the written scope |
Robinhood Cleaners describes commercial exhaust work as addressing hoods, baffle filters, ducts, rooftop fans, access panels, and grease containment. Its service description separates exhaust cleaning from appliance cleaning, filter exchange, fan-belt replacement, grease-trap cleaning, and power washing.
A lower quote may reflect less work, not a better rate. Ask whether it includes commercial kitchen exhaust cleaning across the hood, plenum, ductwork, filters, and fan.
What a complete exhaust service should address
- Hood canopy and interior: Grease removal from visible and interior surfaces.
- Filters: Removal and cleaning, with exchange or replacement identified separately.
- Plenum: Cleaning where grease accumulates behind or above filters.
- Ductwork: Accessible horizontal and vertical runs, with access panels opened where needed.
- Exhaust fan: Cleaning of blades and housing, with belt or component work quoted separately.
- Rooftop containment: Cleaning or servicing where the system has it.
- Protection and cleanup: Covers, containment, runoff control, reassembly, and work-area cleanup.
- Records: Completed areas, deficiencies, and recommended follow-up.
Cleaning the hood surface alone does not establish that the full exhaust path was cleaned. A quote for exhaust cleaning also should not be assumed to include every appliance, floor, wall, grease trap, or exterior surface.
The Details That Move a Restaurant Exhaust Quote
Give the provider measurable details instead of only saying that the kitchen needs hood cleaning.
System size and layout
- Number of hoods and exhaust systems.
- Approximate length and width of each hood.
- Whether one fan serves multiple hoods.
- Approximate duct length and whether the run is horizontal, vertical, or both.
- Number and condition of duct access panels.
- Whether the fan is on the roof, an exterior wall, or another difficult location.
Cooking profile and grease condition
- Cooking equipment under each hood, including fryers, grills, ranges, ovens, or applicable solid-fuel equipment.
- Hours of operation and approximate service volume.
- Unusually heavy smoke or grease-laden vapours.
- Visible grease on the hood, filters, access points, fan, or containment.
- Date of the last professional cleaning and available records.
Access and scheduling
- How technicians will reach the kitchen, access points, roof, or exterior fan.
- Roof restrictions, locked areas, ladders, gates, weather exposure, or landlord requirements.
- Preferred overnight, early morning, or other off-hours window.
- Whether appliances must cool down or be coordinated with the cleaning team.
- Inspection, insurance, lease, or internal record deadlines.
Restaurants with long or heavily used duct runs should budget for commercial kitchen exhaust duct cleaning, not just the visible hood. Access, configuration, and accumulated grease can materially change the work.
An Illustrative Quote Structure to Use for Comparison
A useful quote separates the work into line items. This is a hypothetical comparison format, not a Robinhood Cleaners price list.
| Line item | What to clarify |
|---|---|
| Site protection and access | Equipment covers, containment, ladders, roof access, and setup responsibilities |
| Hood and plenum | Interior and exterior surfaces to be degreased, rinsed, and finished |
| Filters | Cleaning, exchange, or replacement and quantity covered |
| Ductwork | Runs included, access panels opened, and unreachable areas |
| Exhaust fan | Blades, housing, grease paths, hinge arrangements, and excluded repairs |
| Rooftop containment | Whether containment is cleaned, replaced, or excluded |
| Heavy-grease remediation | Separate charges for scraping, repeat treatment, or added access |
| Service window | Overnight, emergency, weekend, or other scheduling conditions |
| Related services | Filter exchange, belt replacement, appliance, grease-trap, or power-washing work |
| Taxes, disposal, and exclusions | Applicable charges and specifically excluded work |
| Documentation | Service date, completed areas, photographs if offered, deficiencies, and next review |
Rewrite competing proposals into the same categories before deciding. This exposes whether one provider priced only a hood and filters while another included the full hood-to-fan path.
One-Time, Recurring, or Urgent Service: Which Model Fits?
Choose one-time service when the system is new to you, overdue, changing ownership, or being assessed before a maintenance plan. The first visit may reveal access, grease, or component conditions hidden from view.
A recurring plan suits restaurants with predictable operating patterns that want scheduled service. Do not assume it is automatically cheaper. Compare scope, frequency, response terms, records, and cancellation conditions. Related reading: How to Compare Mexican Restaurant Catering Options (2026 Guide).
Urgent or heavily soiled service fits significant buildup, a fixed inspection deadline, persistent smoke or odour concerns, or a long gap since professional cleaning. Ask whether additional labour, access work, or a separate repair visit is needed.
Cleaning duration is job-specific. Ask for the arrival window, work duration, equipment shutdown requirements, roof-access timing, and point at which the kitchen can safely reopen.
Ontario Fire Code Context and NFPA 96 Maintenance
Ontario Regulation 256/14 states that a cooking operation producing smoke or grease-laden vapours must have exhaust and fire-protection systems in accordance with NFPA 96, and that required systems must be maintained accordingly.
This does not create one universal price or interval. The maintenance plan should reflect cooking type, volume, grease accumulation, system condition, inspection findings, and applicable requirements.
Cleaning supports maintenance, but an invoice alone does not prove that every regulatory, fire-protection, electrical, mechanical, or building requirement has been satisfied. Keep cleaning records with other relevant documents.
Prepare the Restaurant Before the Cleaning Visit
- Confirm the window: Agree on arrival, duration, shutdowns, and reopening conditions.
- Clear access: Move items from the hood, access panels, fan equipment, and roof entry points.
- Arrange exterior access: Provide keys, codes, landlord instructions, and roof-safety information.
- Coordinate the cookline: Allow equipment to cool and tell staff which appliances will be unavailable.
- Protect food and equipment: Store ingredients and utensils away from the work zone.
- Notify staff: Tell closing, opening, management, and other contractors about the service window.
- Discuss containment and runoff: Agree how wastewater and rooftop grease will be managed.
What to Verify Before You Approve the Invoice
- Compare completed areas with the quote: hood, filters, plenum, ducts, fan, access panels, and containment.
- Confirm filters and access panels were reinstalled and the area was left usable.
- Inspect visible surfaces for remaining grease or damage.
- Request before-and-after photographs if offered.
- Record deficiencies, inaccessible areas, recommendations, and follow-up responsibility.
- File the date, scope, invoice, photographs, and report.
- Confirm the next review or service date.
- Separate cleaning from filter exchange, belt replacement, appliance, and grease-trap work.
Before accepting a proposal, compare its listed components, access setup, fan checks, cleanup, documentation, and exclusions against the other quotes.
Routine Staff Cleaning Is Not Full Exhaust-Service Cleaning
Staff can follow routine procedures for visible surfaces, removable filters, and day-to-day grease control where those tasks suit the equipment and workplace procedures.
Professional service addresses plenums, concealed ducts, rooftop fans, access panels, containment, and the connected hood-to-fan path. It may also require power isolation, specialized equipment, chemical controls, and work at height.
Do not treat an improvised hood wipe-down or unprotected rooftop work as a substitute for professional exhaust-system cleaning. Grease can remain concealed while the restaurant assumes the system was serviced.
A Better Way to Request a Quote in Ontario
Send the provider enough information to price the actual job:
We operate a [restaurant type] in [Ontario service location]. We have [number] exhaust system(s), hood(s) approximately [length], and duct runs that are [layout]. Cooking equipment includes [equipment]. The last professional cleaning was [date or unknown]. Visible concerns include [grease, odour, airflow, access, or inspection issue]. Roof and duct access is [description]. We need [one-time, recurring, or urgent] service during [preferred window]. Please quote the hood, filters, plenum, ductwork, fan, containment, access, cleanup, documentation, exclusions, and separate related services.
Robinhood Cleaners states that it serves restaurants, cafeterias, and institutional kitchens across Ontario, with quick service in Southern Ontario and 24/7 availability.
Frequently Asked Questions
How much does it cost to clean a restaurant hood?
Broad market context places many small restaurant hood jobs around $200 to $500, while larger or more complex systems can cost $1,500 to $3,000 or more. Hood length, filters, grease, access, cooking volume, and scope determine where a quote falls. Ask whether the quote includes the plenum, ducts, fan, containment, protection, cleanup, and records.
How much is it to clean a complete restaurant exhaust system?
A small complete system may fall around $200 to $500 in broad market context, a medium system around $800 to $1,500, and a large or complex system around $1,500 to $3,000 or more. The quote must reflect the system’s components, configuration, access, condition, and service window. Compare line items instead of relying on a headline average.
What information does a cleaner need?
Provide hood dimensions, system count, duct layout, access details, fan and roof access, cooking equipment, volume, grease condition, last cleaning date, service window, and documentation needs.
Does recurring service always cost less?
No. Its value depends on frequency, scope, response terms, and system condition. Compare the work and records delivered at each visit.
How long does professional cleaning take?
The duration depends on systems, configuration, access, grease, preparation, and included work. Request a job-specific arrival and completion window.
Can staff cleaning replace professional service?
No. Staff care supports routine surface maintenance but does not replace professional cleaning of plenums, concealed ducts, rooftop fans, access panels, and the complete exhaust path.
Choose the Quote That Shows the Work
The strongest quote is not necessarily the lowest total. It identifies the system, names included components, states exclusions and scheduling conditions, and provides records. To request a scope-based estimate, give Robinhood Cleaners your dimensions, system count, cooking profile, access details, last service date, and preferred service window, then ask about its commercial kitchen hood cleaning service.
