Commercial Hood Cleaning in Hamilton
Commercial hood cleaning is the physical scraping and degreasing of a kitchen exhaust system back to bare metal, covering the canopy, the baffle filters, the plenum behind them, the duct running through the building, and the fan on the roof. Hamilton Hood Cleaning performs that job in Hamilton kitchens to the NFPA 96 standard, in a single visit booked overnight or between service hours, starting at $385 for a single hood up to ten feet. The visit ends with before-and-after photographs of every surface that was cleaned and a signed health and safety certificate referencing the standard, which is what the Hamilton Fire Department and an insurance adjuster both ask to see. This page walks through the whole job so you know what you are buying before a crew turns up.
What a hood cleaning visit covers, start to finish
Four stages, identical on every job, whether the kitchen is a twelve-seat storefront or a banquet hall running four canopies.
Protect the kitchen first
The cook line, the pass and the floor are covered before a single container of degreaser is opened. Equipment that cannot be covered gets moved. This stage takes longer in a narrow lower-city kitchen than anywhere else on the route, and skipping it is the reason some operators come back to a greasy floor and a grit-covered flat top.
Filters out, canopy and plenum down to metal
Baffle filters come out and are soaked separately. The canopy interior, the grease gutter and the plenum cavity behind the filters are then scraped and degreased. The plenum is the part most often left alone, because it is out of sight from the floor and nobody complains about it until an inspector looks.
Duct and rooftop fan opened
Access panels are opened along the horizontal and vertical runs, the duct is cleaned through, and the crew goes to the roof for the fan housing and the blower wheel. This is the part a canopy-only quote leaves out. If a section genuinely cannot be reached, it is written down as not accessible along with what it would take to reach it.
Photographed, certified, handed back food-ready
Every cleaned surface is shot before and after from matching angles. The signed certificate referencing NFPA 96 is completed on site. Filters go back in the correct orientation, covers come off, floors are wiped, and the next interval is booked before the crew leaves.
Proof of WSIB coverage and liability insurance is sent over before any of this starts, not afterwards. Property managers, school boards and food service contractors can be named as additional insured on request.
Where the job changes across Hamilton kitchen districts
The cooking is broadly the same across the city. The building is not, and the building is what decides how long a visit takes and where the risk sits.
| District | Typical building | What changes about the job |
|---|---|---|
| James Street North and King William Street | Narrow converted storefronts | Short vertical riser straight up to a flat roof, which is the easy part. Rear access is tight, so equipment staging and protecting a small kitchen take a bigger share of the visit than the cleaning does. |
| Locke Street South and Ottawa Street North | Older mixed-use, restaurant under residential | People are asleep upstairs. Noise control and roof access timing drive the schedule, so the visit is planned around the tenants above as much as around last service. |
| Concession Street, downtown Dundas, Ancaster village | Low-rise strips | Roof-mounted fans reached by ladder rather than by an interior stair. Ladder setup and weather decide whether the rooftop stage happens that night, so it gets confirmed at the walk-through instead of assumed. |
| Stoney Creek and Ancaster business parks | Newer builds, purpose-designed kitchens | Long horizontal duct runs with proper access panels and larger makeup air units. Easier to clean thoroughly and easier for a contractor to skip quietly, which is why the photo set covers each panel along the run. |
| Downtown towers and multi-tenant buildings | Shared duct risers | One tenant grease load becomes the whole riser problem. Each kitchen gets its own quote and its own certificate, and the shared section is handled as separate scope with the property manager. |
Outside the city limits the same job runs on scheduled route days. See Brantford, Grimsby and the full areas served list.
Overnight cleaning vs between-service cleaning in a Hamilton kitchen
Both keep the kitchen open. Which one suits you depends on what your kitchen does between meals, not on what the contractor prefers.
| Overnight, after last service | Between service hours | |
|---|---|---|
| Best for | Restaurants, bars and quick service with a hard close | Banquet halls, event venues, campus and healthcare serveries with gaps in the day |
| Equipment must be cold | Yes, and after a full night it usually is | Yes, which is the real constraint. A short gap between meal periods may not be long enough for a fryer bank to cool |
| Rooftop stage | Done in the dark with lighting, fine on a flat roof with stair access | Easier and safer, particularly on a Mountain plaza reached by ladder |
| Neighbours above the kitchen | The constraint on Locke Street and Ottawa Street, where residential sits above the restaurant | Usually the better option in those buildings |
| Effect on price | None. Both start from $385 for a single hood up to ten feet | None. Access and hood count move the number, not the hour |
How much does commercial hood cleaning cost in Hamilton in 2026?
Commercial hood cleaning in Hamilton starts at $385 per visit for a single-hood kitchen up to ten feet, and from $725 per visit for a multi-hood kitchen of two to four canopies. Campus, hospital, contract-catered and multi-tenant kitchens are quoted after a free walk-through.
Three things move a Hamilton quote, and none of them is the neighbourhood. The first is hood count and length, because that is simply more surface. The second is access: a fan on a flat roof with stair access is a different afternoon from the same fan on a strip plaza reached by ladder, and a shared riser in a downtown building is different again. The third is condition on arrival. A system that has been on its correct interval cleans predictably. A system taken over from a previous operator with no records may need a longer first visit to establish a baseline, and it is better to know that before booking than to discover it at two in the morning.
What does not move is the deliverable. Every quote covers the signed certificate referencing NFPA 96, the before-and-after photo report, and proof of WSIB and liability coverage before the crew arrives. The quote is written, it lands within 24 hours, and the invoice matches it. A full breakdown of what pushes the number up or down is in the exhaust cleaning cost guide.
Best commercial hood cleaning in Hamilton for a kitchen with no records
Taking over a lease with no cleaning history is the most common reason a Hamilton operator calls, and it is a solvable problem with one documented visit.
An empty file is not a small problem. Without dated evidence, an inspector has nothing to check against, an insurer has nothing to rely on after an incident, and you have no idea whether the duct above your ceiling has been opened in five years or in fifteen. The previous operator record, if one existed, does not follow the lease.
The fix is a full-system clean carried out and documented in your name, which becomes the baseline every later visit is measured from. The walk-through beforehand matters more than usual here, because a neglected system tells you things a phone call cannot: whether the fan has ever been tilted back, whether access panels exist along the horizontal run, whether the plenum has been touched at all. That walk-through is free, and the honest outcome is sometimes that a hinge kit needs fitting before the fan can be properly serviced on future visits.
Once the baseline exists, the interval takes over. NFPA 96 assigns it by cooking volume, and the cleaning frequency guide explains how a kitchen is placed in a tier. If you are not sure whether your hood is even in scope, the Type 1 hood explainer is the place to start. To book the walk-through, call 289-796-0840 or use the contact page.
Hood cleaning in Hamilton: frequently asked questions
The questions that come up during a walk-through, answered here first.
How long does a hood cleaning visit take?
A single-hood kitchen up to ten feet is normally one overnight visit, covering protection, filters, canopy, plenum, duct, roof, photographs and the certificate. A multi-hood kitchen of two to four canopies is still one visit, worked in sequence. What actually stretches a visit is not hood length but access and condition: a tight rear entrance on a converted James Street North storefront, a ladder-only roof, or a system that has not been properly opened in years. The walk-through is where that gets established, so the booked window is realistic rather than optimistic.
Does the canopy get cleaned if only the duct is the problem?
The whole path is cleaned as one job, because the standard applies along the whole path rather than to one section of it. Grease that is left in the plenum simply loads the duct again, so cleaning a duct beneath a dirty plenum buys weeks rather than an interval. Where a system is genuinely being caught up in stages, that gets stated on the certificate, because a document should never imply coverage of something nobody opened.
What happens if part of my system cannot be reached?
It gets written down as not accessible, along with what would make it reachable. That is the whole answer, and it is deliberately unglamorous. The common cases in Hamilton are a rooftop fan with no hinge kit that cannot be tilted back safely, a duct run with no access panels installed, and a shared riser section that belongs to the building rather than to your kitchen. Certifying something nobody opened is worse than useless, because it gives an operator confidence in a gap. Hinge kit installation solves the first case permanently.
Is hood cleaning the same as kitchen exhaust cleaning?
The terms are used interchangeably by most operators, and on this site the visit described above covers the full path either way. The distinction worth knowing is commercial rather than technical: some contractors quote a canopy-and-filters visit and call it hood cleaning, which is a legitimate maintenance service and not the full-system clean the code interval refers to. Ask any contractor whether the fan gets opened. The kitchen exhaust cleaning page sets out the full-system scope in detail.
Do you clean campus, hospital and contract-catered kitchens in Hamilton?
Yes, and they are quoted after a free walk-through rather than off a price list, because access and scheduling are the variables rather than hood length. Those kitchens generally need proof of WSIB and liability insurance before a booking is confirmed, work planned around a meal calendar that never fully stops, and documentation clean enough to sit in a procurement file. Both records are standard on every job here. The about page covers how that segment is handled.
