Hood Cleaning Services in Whitby
Hood Cleaning Services in Whitby are the professional cleaning of the three parts that sit directly above a commercial cook line: the stainless canopy, the baffle filters in its slot, and the plenum chamber behind the filters where most of the grease ends up. Whitby Hood Cleaning lifts the filters into a heated soak tank, strips the canopy and plenum back to bare metal, photographs each surface before and after, and signs a health and safety certificate referencing the published NFPA 96 standard. The interval follows what the line cooks, not the calendar. Pricing starts from $385 per visit for a single-hood kitchen up to ten feet.
Canopy, baffle filters and plenum: what commercial hood cleaning covers
The canopy is the stainless box you see from the floor. Its purpose is capture and containment: the hot plume off a charbroiler or a tandoor rises, spreads, and has to be held inside the lip of the canopy before it spills back over the cooks.
A slot along the back edge of the canopy holds the baffle filters. Air is pushed through a zigzag of metal blades and changes direction several times. Each turn throws grease onto the blades, where it drains into a trough.
The plenum is the sealed chamber between the filters and the duct collar. The grease the blades shed drains into it; the grease they miss ends up on its walls. You cannot see it from the line, which is why a canopy wiped every night can hide the heaviest deposit in the kitchen. Past the collar, the duct belongs to the kitchen exhaust cleaning page; the fan on the roof belongs to the exhaust fan repair page.
Baffle filters vs mesh filters in a Whitby kitchen
Baffle filters are the type NFPA 96 expects above any appliance that produces grease. A filter full of grease is fuel hanging over the flame.
How the two differ. A mesh filter is a woven aluminum pad that traps grease by soaking it up, so it gets more flammable every shift. A baffle filter has no pad. It catches grease by turning the air, and the grease runs off the blades. Older downtown Whitby kitchens still turn up with mesh, and the quote itemises a baffle set.
The soak-tank method. Filters go straight into a heated caustic tank on the truck. A dish cycle removes the surface film and leaves the baked-on layer where the blades meet the frame. The tank dissolves that layer while the crew works on the plenum.
When a filter is replaced. Once a blade is bent, the air passes straight through and the grease goes with it. A corroded frame, a loose filter, or a set that leaves a gap at either end gets replaced. Replacement is listed on the quote and approved by you before the visit.
Wall canopy, island and backshelf hoods in Whitby kitchens
Each of the three hood styles loads grease in a different place.
Wall canopy. The hood most Whitby kitchens have: mounted on the back wall above a straight row of appliances. Franchise units on Thickson Road and pubs on Brock Street nearly all run one. Grease builds in the two plenum corners against the wall.
Island canopy. Hung over a cook line in the middle of the room with no wall on any side, the style banquet and community hall kitchens tend to have. With nothing behind it to help capture, an island hood loads its filters from both faces.
Backshelf hood. A short, shallow hood set tight against the wall behind a counter line, typical of quick-service units on Dundas Street. The plenum is small and fills fast, and the filters sit close enough to a griddle to take direct heat.
Best commercial hood cleaning in Whitby for a tandoor, charbroiler or bakery line
Whitby Hood Cleaning sets the interval from the appliance under the hood and the hours it runs.
| Tandoor and charbroiler line vs bakery line vs care kitchen vs event kitchen | Where the grease lands first | Interval that fits |
|---|---|---|
| Tandoor, charbroiler and fryer-bank line (Indian, Hakka and burger kitchens on Dundas Street and Thickson Road) | The filters, within weeks. No other line puts more grease into the air per hour than a fryer bank next to an open flame. | Every three months, and sooner when the line runs late or the slot still holds mesh. |
| Bakery ovens and doughnut fryers (bakeshops in downtown Whitby and on Baldwin Street in Brooklin) | The plenum. Sugar-laden fryer vapour slips past the baffles and glazes the chamber walls. | Twice a year for an oven-only shop, every three months once a doughnut fryer runs from early morning. |
| Care and residence kitchen (retirement residences in Whitby Shores and care kitchens near Lakeridge Health Whitby) | Everything, steadily. Three services a day, seven days a week, outruns a busy restaurant. | Every three months in most cases, because the kitchen never closes for a season. |
| Church, Legion and arena kitchen (halls that cook for events, then sit idle for weeks) | The canopy corners, slowly. Loading is low, but the last cleaning date is often lost. | Once a year where use is light, twice a year where the hall runs a weekly dinner or a fish fry. |

Hood cleaning services in Whitby: frequently asked questions
What is the difference between hood cleaning and kitchen exhaust cleaning?
Hood cleaning covers the three parts above the line: canopy, baffle filters and plenum. Kitchen exhaust cleaning covers the duct after the collar. In Whitby the two are usually booked as one overnight job; the duct half is described on the kitchen exhaust cleaning page.
Can kitchen staff wash the baffle filters between visits?
Baffle filters should go through the dish machine weekly to keep surface film off the blades. The dish machine cannot dissolve the baked-on layer where the blades meet the frame, and that layer is what the soak tank is for.
Why does a hood that looks clean still fail a fire inspection?
Whitby Fire and Emergency Services looks behind the filters, not at the face of the canopy. The plenum is never touched between professional visits, and a plenum wall over the 0.078 inch limit fails the system whatever the outside looks like.
Is the rooftop fan included in a hood cleaning visit?
A full-system visit opens and cleans the fan, and every hood visit includes a look at it. Belts, bearings, motors and hinge kits are a separate service, described on the exhaust fan repair and installation page.
How long does a single-hood cleaning take in Whitby?
One wall canopy with usable baffles fits inside a single overnight window, soak, plenum, photographs and line reset included. Add canopies or an island hood and the job runs longer.
