Exhaust Hood Cleaning in Niagara Falls
Exhaust Hood Cleaning in Niagara Falls is the service that returns a commercial kitchen canopy to bare stainless so it catches smoke and grease again: the canopy walls and lip, the filters in their track, and the plenum chamber behind the filters. Niagara Falls Hood Cleaning degreases each surface, photographs it before and after, and signs a health and safety certificate referencing the published NFPA 96 standard. A single hood up to ten feet starts at $585 per visit, booked overnight or between services anywhere in the Niagara Region.
Why a greasy canopy stops capturing smoke
A canopy has two jobs. Capture means pulling the rising plume in before it spills into the room. Containment means holding it inside the hood long enough for the fan to draw it out. Grease works against both.
As the filters load, less air moves through them, so the draw at the canopy lip weakens. Smoke that used to disappear now rolls over the front edge and hangs above the pass. Cooks feel the heat, the smoke alarm near the line goes off, and a film settles on the walls and ceiling of the kitchen.
The plenum is where the problem hides. It is the closed box behind the filter track, and the grease that slips past the filters coats its walls, its ceiling and the collar opening. You cannot see it with the filters in, and it often holds more grease than anything else under the hood.
Hood vent cleaning: how the canopy, filters and plenum get done
Hood vent cleaning in Niagara Falls follows the same order on every visit, from the top of the plenum down to the drip trough.
Cover and contain. The crew wraps the fryers, ranges and flat-tops under plastic and hangs a catch sheet from the canopy lip. Runoff goes into a drain line and a bucket, not onto your floor.
Filters in place, then out. The crew sprays the filters in their track first to loosen the surface load, then lifts them out. That gives clear access to the track and the rail behind it.
Plenum first. Degreaser goes onto the plenum ceiling and walls and around the collar opening, where the heaviest layer usually sits. The crew scrapes, then rinses with hot water until the stainless shows.
Canopy walls, lip and trough. The inside faces, the corners against the back wall, the light fixtures and the grease trough are cleaned last, so nothing drips onto a finished surface.
Refit and photograph. Filters go back with no gaps in the track. Every surface is photographed again, and the photographs go with your certificate. Duct work past the collar is on the kitchen exhaust cleaning page.
Hood-only clean vs full vent clean in Niagara Falls, seen from the canopy
A hood-only clean treats the canopy surfaces. A full vent clean treats everything behind the filters that decides how well the hood draws.
| At the canopy | Hood-only clean | vs full vent clean |
|---|---|---|
| Capture at the lip | Looks better, draws about the same, because the airflow restriction sits behind the filters. | Draw returns once the filters and plenum are open, so smoke stays under the hood. |
| Filters | Wiped or sprayed on the face while they stay in the track. | Sprayed in place, lifted out, cleaned through every fold and refitted tight. |
| Plenum and collar | Not reached. The thickest layer under the hood stays in place. | Scraped and rinsed to bare metal, measured against 0.078 inches, and photographed. |
| What the paperwork says | Canopy surfaces only. | Canopy, filters and plenum, each with a before-and-after photograph. |

Best exhaust hood cleaning in Niagara Falls for a wall, island, backshelf or deep canopy
The hood style decides where grease collects first and how the crew rigs containment.
Wall canopy. The canopy sits flat against a wall over a single row of appliances. The back wall helps containment, so grease packs into the two rear corners of the plenum and along the back of the filter track.
Island canopy. The canopy hangs from the ceiling over an open line with no wall behind it. Cross drafts from doors and servers pull the plume sideways, so the outer edges and both ends of the lip load before the middle.
Backshelf hood. A low, shallow hood mounted close to the cooking surface. Its small plenum fills fast, and the crew works it on hands and knees under a catch sheet.
Deep canopy over a charbroiler. A tall canopy over a flame that throws grease upward. The extra inner height means more surface, and the upper walls load between visits even when the lip looks clean. Charbroiling is one of the high-volume types listed in NFPA 96.
If you are not sure whether your hood is a Type 1 grease hood, the Type 1 vs Type 2 guide explains the difference.

Exhaust hood cleaning in Niagara Falls: frequently asked questions
What is the difference between hood vent cleaning and exhaust hood cleaning?
Hood vent cleaning and exhaust hood cleaning are two names for the same service: the canopy, the filters and the plenum. Duct and fan work are separate services with their own pages.
Why does my hood still smoke after staff clean the filters?
Staff cleaning reaches the filter faces, not the plenum behind them. A loaded plenum and collar restrict airflow, so the canopy keeps losing capture until that chamber is scraped and rinsed.
How long does a hood vent cleaning take?
A single canopy up to ten feet usually fits inside one overnight window, with setup, cleaning and photographs done before the morning shift. Several canopies are scheduled as one job.
Does an island canopy cost more to clean than a wall canopy?
Price follows canopy length and count, not style. An island canopy takes more containment rigging because there is no wall behind it, and the walk-through accounts for that.
How often should my exhaust hood be cleaned?
Cooking type and volume set the interval. The published intervals are on the NFPA 96 page, and the frequency guide shows how Niagara kitchens set theirs around the season.
