Commercial kitchen exhaust cleaning should cover the connected exhaust path, not just the visible hood: hood, filters, plenum, accessible ductwork, and exhaust fan. Cleaning time and price depend on system size, grease accumulation, access, condition, containment, and documentation, so operators should request an itemized scope instead of relying on a flat Ottawa estimate.
This guide is for Ottawa-area restaurant owners, managers, chefs, facilities teams, and other commercial food-service operators preparing a service request. Robinhood Cleaners’ website describes commercial kitchen exhaust cleaning for hoods, filters, ducts, and fans. Confirm availability for your Ottawa-area site before booking.

What commercial kitchen exhaust cleaning should include
Commercial kitchen exhaust cleaning is the removal of grease and residue from the exhaust system that carries heat, smoke, and cooking vapour away from the cookline. A complete scope normally follows the system from the hood canopy through the filters, plenum, ductwork, and exhaust fan.
Hood cleaning and exhaust cleaning are often used as if they mean the same thing. For a quote, however, ask whether “hood cleaning” includes the ductwork and fan or only the visible canopy and filters. A commercial kitchen hood cleaning service should state the exact components covered.
| Component | What it does | What to confirm in the quote |
|---|---|---|
| Hood canopy | Captures heat, smoke, and grease-laden vapour above the cooking line. | Whether exterior and interior surfaces, seams, corners, and the hood underside are included. |
| Grease or baffle filters | Collect grease particles before air enters the duct. | Whether filters are removed, cleaned, exchanged, inspected, dried, and reinstalled. |
| Plenum | Connects the hood opening to the duct entrance. | Whether the plenum is degreased instead of being left as an unseen surface. |
| Horizontal and vertical ducts | Move exhaust air from the hood to the discharge point. | How access panels will be reached and whether accessible duct sections are included. |
| Exhaust fan | Pulls air through the system and discharges it outdoors. | Whether the fan housing and blades are cleaned and whether access limitations are recorded. |
Appliances, grease traps, make-up air equipment, walls, floors, and general kitchen cleaning are related services, but they are not automatically part of exhaust cleaning. If you need them, list them separately so the quote does not appear comprehensive while leaving important work outside the scope.
Prepare an Ottawa service request before asking for a quote
The fastest way to obtain a useful estimate is to send a short, accurate site brief. A provider can plan the visit more effectively when the request identifies the exhaust layout, access conditions, operating constraints, and records you need after the work.
Include these details in your first message or call:
- Restaurant type, cooking methods, operating hours, and preferred service window.
- Number of hoods and approximate length of each hood.
- Whether the duct runs horizontally, vertically, or through multiple levels.
- Fan location, roof or exterior access requirements, and the person who controls building access.
- Known access panels, ceiling restrictions, locked areas, or landlord requirements.
- Date of the last professional cleaning, if known, and any visible grease accumulation.
- Smoke escape, odours, grease drips, unusual fan noise, or airflow changes.
- Whether you also want separate pricing for filter exchange, fan-belt work, appliance cleaning, or grease-trap service.
Photographs of the hood, filters, access panels, fan, and any difficult approach can help clarify the request. They do not replace a site assessment, but they can prevent a quote from being based only on the visible canopy.
How often should professional exhaust cleaning be scheduled?
There is no single useful interval for every restaurant. Set the schedule around cooking volume, menu, grease production, operating hours, fuel and equipment use, visible accumulation, and the condition of the existing system.
Ontario Regulation 213/07 requires a cooking operation that produces smoke or grease-laden vapours to have an exhaust and fire-protection system maintained in accordance with NFPA 96. That requirement establishes the maintenance context, but it does not turn every Ottawa kitchen into the same scheduling case. Read the Ontario Fire Code provision when reviewing your maintenance responsibilities.
For broader guidance on comparing service scope, timing, and providers, use this provider comparison guide. For this Ottawa request, focus first on describing your own system accurately.
Use these signs when planning the next visit
- A menu built around frying, grilling, wok cooking, charbroiling, or other high-grease processes generally needs closer attention than a low-grease operation.
- Long operating hours and multiple busy service periods increase the amount of vapour passing through the system.
- Grease visible beyond the normal filter area, heavy deposits in access points, smoke escape, or recurring odours are reasons to reassess the current schedule.
- A new menu, equipment change, renovation, or substantial increase in volume can make an old maintenance interval unsuitable.
Routine staff cleaning between visits supports the system, but it does not replace professional access to the plenum, ducts, and exhaust fan.
How long does it take to clean a commercial kitchen hood?
A commercial kitchen hood or exhaust-system cleaning does not have a reliable universal duration. A small, accessible system with light accumulation requires less time than a long system with heavy grease, restricted access, multiple hoods, or difficult fan and roof access.
For planning purposes, provide the number and approximate length of hoods, the duct configuration, fan location, access-panel details, previous service date, and the condition you can observe. Also allow time for kitchen protection, filter handling, degreasing, containment, rinsing, cleanup, reinstallation, and final checks. The provider can then give a more credible scheduling estimate instead of a generic promise.
What changes a commercial exhaust-cleaning quote?
Ottawa duct and exhaust-cleaning prices vary because the work is priced around the system and the job conditions, not simply the visible width of the hood. No responsible quote should be presented as a universal flat Ottawa price without seeing or accurately describing the installation.
Give the provider a useful service brief
- System size: number of hoods, approximate hood lengths, duct route, and whether the system has horizontal runs, vertical risers, or more than one fan.
- Access: location and condition of access panels, ceiling or wall restrictions, fan position, and the route to any roof or exterior equipment.
- Grease condition: last professional cleaning, visible buildup, neglected sections, smoke or odour complaints, and any known leakage.
- Equipment: fryers, grills, ranges, charbroilers, ovens, or other appliances connected to the exhaust system.
- Site requirements: shutdown window, building access, alarm or control procedures, protection of nearby equipment, and cleanup expectations.
- Records: service date, components addressed, findings, photos if available, limitations, recommendations, and suggested next timing.
Compare quotes by scope, not just total
| Ask about | Why it affects the comparison |
|---|---|
| Hood, filters, plenum, ducts, and fan | A hood-only price cannot be compared fairly with a full-system price. |
| Access panels and restricted areas | Unreachable sections should be identified instead of silently excluded. |
| Containment and protection | Nearby equipment, floors, walls, and roof areas need a defined protection and cleanup plan. |
| Scheduling | After-hours or restricted access can change labour planning and the available service window. |
| Related work | Filter exchange, fan-belt work, appliance cleaning, or grease-trap service should be listed as separate inclusions or exclusions. |
| Documentation | A clear record helps your team track what was done and what still needs attention. |
Request an itemized quote that identifies exclusions. If one proposal includes duct access, fan cleaning, containment, and records while another covers only the canopy and filters, the lower total may not represent the lower cost for the same job.
What happens during a professional cleaning visit?
A professional visit should begin with an assessment of the hood, filters, access points, duct route, fan, visible buildup, and site constraints. The work then proceeds through protection, controlled shutdown, cleaning, reassembly, and documentation.
- Assess the system: Identify the components, access points, condition, and areas that require special planning.
- Coordinate the shutdown: Arrange for the cooking line and exhaust equipment to be safely out of operation during the work.
- Protect the area: Cover or shield nearby surfaces and equipment, and plan containment for cleaning solution, grease, and runoff.
- Handle the filters: Remove filters for cleaning or exchange, then keep them protected until they are ready to reinstall.
- Degrease the hood and plenum: Clean accumulated residue from accessible interior and exterior surfaces.
- Reach the ductwork: Use available access points to clean accessible horizontal and vertical sections of the exhaust path.
- Clean the exhaust fan: Address accessible fan housing and blades, while recording any access or condition limitations.
- Contain and remove waste: Manage grease, cleaning solution, and runoff so the surrounding kitchen and exterior areas are left in an acceptable condition.
- Reinstall and check: Return filters and accessible components to position, restore the operating area, and check for obvious issues before reopening.
- Record the work: Document the date, scope, findings, limitations, recommendations, and photos or tagging when supplied.
The exact method depends on the equipment, surface, access, and buildup. A provider should explain how the proposed process reaches the system rather than promising that a quick surface wash covers every component. Commercial kitchen exhaust duct cleaning is specifically concerned with residue throughout the path from hood to fan.
How to prepare the kitchen before cleaners arrive
Good preparation reduces delays and helps the provider clean the intended components. Assign one site contact who can explain the exhaust layout, approve the shutdown, and resolve access questions.
- Choose a service window that allows the cooking line and exhaust system to remain out of operation for the planned work.
- Clear movable items, food, utensils, and loose supplies from beneath and around the hood.
- Identify electrical, fan, and control locations, but leave shutdown and restart procedures to the responsible personnel.
- Locate filter storage, access panels, roof or exterior fan access, and any building restrictions before the appointment.
- Tell the provider about ceiling access, locked areas, roof rules, alarm procedures, and vulnerable equipment.
- Record any known leaks, fan noise, airflow changes, smoke escape, grease drips, or previous access limitations.
- Plan the reopening check, including filter placement, equipment reset, visible cleanup, and confirmation that the cookline can return to service.
Access arrangements vary by building and exhaust design. Confirm who controls roof, exterior, ceiling, electrical, and fire-safety access before the service date instead of discovering a restriction after the crew arrives.
What records should you keep after service?
Keep a service record that shows what was addressed and what remains unresolved. Useful records support internal maintenance tracking and preserve the exact work history for the kitchen.
Post-service records checklist
- Service date and the restaurant or facility identity.
- Hood, filter, plenum, duct, and fan components included in the work.
- Access limitations or sections that could not be reached.
- Condition findings, visible damage, and recommended corrective work.
- Photos or service tags when supplied.
- Cleaning, filter exchange, fan-belt, or related work listed separately.
- Recommended next service timing and the reason for that recommendation.
- Name of the service provider and the person who reviewed the report.
File the report with earlier service records, equipment information, and any follow-up work orders. A simple chronological record makes it easier to see missed visits, recurring access problems, changing grease loads, and recommendations that still need action.
How to choose and contact a provider for an Ottawa-area kitchen
A kitchen exhaust cleaner is a specialist or company that removes grease and residue from commercial exhaust components such as hoods, filters, plenums, ducts, and fans. The best choice is not necessarily the fastest listing or the lowest initial quote. It is the provider that can define the reachable scope, explain limitations, coordinate the shutdown, and supply a useful record.
For an Ottawa-area request, ask these questions before booking:
- Does the quote include the hood, filters, plenum, ductwork, and exhaust fan?
- Which sections require access panels, ceiling access, roof access, or another site arrangement?
- What is included in protection, containment, rinsing, and final cleanup?
- Which related services are separate from exhaust cleaning?
- What information is needed to estimate the service window?
- What records, findings, photos, or tags will be supplied after the visit?
- How does the recommended frequency relate to the kitchen’s menu, volume, hours, and observed buildup?
