Kitchen Exhaust Cleaning in Richmond Hill
Kitchen Exhaust Cleaning in Richmond Hill is the cleaning of the hidden grease duct that carries cooking vapour away from your hood: the horizontal run above the ceiling, the vertical riser that climbs to the roof, and the access panels that let a technician reach inside each section. Richmond Hill Hood Cleaning opens every reachable panel, scrapes the duct walls down to bare metal, checks the NFPA 96 grease limit of 0.078 inches from the collar to the fan inlet, and lists each section on a signed certificate. Pricing starts from $585 per visit.
Commercial kitchen exhaust cleaning in Richmond Hill: collar, horizontal run, riser and access panels
The duct collar is the square opening on top of the hood where the duct begins. Vapour cools the moment it leaves the heat of the line, so the first few feet past the collar take a heavy drop-out.
The horizontal run travels above the ceiling tiles, sometimes the full depth of a plaza unit, before it reaches the shaft. Grease pools on the duct floor and packs against the outer wall of every elbow.
The riser is the vertical leg that climbs through the building to the roof. Condensed grease slides down its walls and collects at the bottom turn, a spot nobody sees from the kitchen or the roof.
Access panels are bolted, gasketed doors cut into the duct wall. No panel means no cleaning, so the walk-through marks every section that lacks one. The canopy and filters are on the hood cleaning services page, the rooftop fan on the exhaust fan repair page.
Hood-only vs full-system kitchen exhaust cleaning in Richmond Hill
A Richmond Hill Fire and Emergency Services inspector can tell the two records apart in seconds.
| Duct section | Hood-only vs full-system: hood-only | Full-system |
|---|---|---|
| Collar and first few feet | Reached by arm through the filter slot, if at all. | Opened at the first panel, scraped and measured. |
| Horizontal run and elbows | Left closed and left off the paperwork. | Every panel opened, each elbow scraped, a photograph taken inside each one. |
| Bottom of the riser | Never reached. | The pooled grease at the turn removed and measured. |
| Rooftop fan inlet | Never reached. | Cleaned from the roof side and measured. |
| What the certificate says | The hood only. | Each section cleaned, and each section not reached with the reason. |
What the certificate does and does not assert is explained on the NFPA 96 page.
Hood vent cleaning in Richmond Hill: what the word vent should include
Most owners call it hood vent cleaning. The vent is everything the smoke passes through after it leaves the hood: collar, run, elbows, riser and the fan on the roof. A quote that says hood vent cleaning but only prices the filters and canopy leaves the longest and most flammable part of the system out.
Before you book, ask which duct sections will be opened and named on the certificate. Richmond Hill Hood Cleaning writes that list onto the quote after the walk-through.
Best kitchen exhaust cleaning services in Richmond Hill for plaza units and mixed-use buildings with a long shared riser
Richmond Hill Hood Cleaning cleans each tenant branch up to the junction and quotes the shared riser separately to the building owner.
Many plazas on Highway 7 and Yonge Street were built with several food units venting into one shaft. A mixed-use building puts restaurants at street level and residences above, so the riser can climb many storeys before it reaches a fan. Every kitchen on the shaft adds grease to it, and no single tenant owns it.
The split is written down first. Each unit owns its hood and branch duct to the junction; the riser and fan belong to the building. A separate riser quote goes to the property manager with proof of WSIB coverage and liability insurance. Franchise head offices that file certificates centrally are covered on the who we serve page.
Grease exhaust cleaning to 0.078 inches along the whole path
NFPA 96 applies one grease limit, 0.078 inches, to every surface in the system. A duct above a drop ceiling gets no extra allowance. Richmond Hill Hood Cleaning takes readings at four points on a full-system visit: the collar, the outer wall of each elbow, the bottom of the riser and the fan inlet.
A section with no panel gets no reading, and it is never listed as cleaned. The certificate marks it as not accessible and states where a new panel would open it, so the gap is on paper instead of hidden.
Creosote in the duct from charcoal grills and wood-fired ovens
Gas cooking leaves grease. Charcoal and wood leave something harder. Smoke tar condenses as creosote on duct walls cooler than the fire, glazes over and locks the grease inside it. That glaze ignites at a lower temperature than grease alone and shrugs off the degreaser that clears a fryer duct.
The charcoal kebab grills and wood-fired pizza ovens across Richmond Hill fall under the monthly interval NFPA 96 publishes for solid-fuel cooking for this reason. A creosote-lined duct comes clean by hand scraping section by section, and solid-fuel duct work is quoted per job after inspection.
Where to find kitchen exhaust cleaning services near me in Richmond Hill
Richmond Hill Hood Cleaning traces duct runs across Richmond Hill, Oak Ridges and Lake Wilcox, and Thornhill east of Yonge Street.
Shared risers are most common in the plazas on Highway 7 and the mixed-use buildings along Yonge Street. A standalone restaurant on Bayview Avenue or Leslie Street usually has its own short duct and its own fan. The crew works from Langstaff and Richvale north past Major Mackenzie Drive and Elgin Mills Road. Neighbourhood detail is on the areas served page.

Kitchen exhaust cleaning services in Richmond Hill: frequently asked questions
Who pays to clean a shared riser in a Highway 7 plaza?
The building owner pays in most leases, because the riser and fan are common elements. Each tenant pays for its own hood and branch duct. Richmond Hill Hood Cleaning quotes the branch and the riser as two separate documents.
How many access panels does a kitchen exhaust duct need?
A kitchen exhaust duct needs a panel wherever a scraper cannot otherwise reach: near the collar, at each elbow and at the foot of the riser.
What happens to duct sections the crew cannot reach?
Unreached sections go on the certificate as not accessible, with the reason and the panel location that would open them. No section is ever marked clean from a glance through the collar.
Is hood vent cleaning the same as kitchen exhaust cleaning?
Hood vent cleaning and kitchen exhaust cleaning describe the same job when the quote includes the duct and fan. If a hood vent quote covers only filters and canopy, the duct stays dirty. Ask which sections are named before you book.
Does the 0.078 inch limit apply inside the riser of a mixed-use building?
The 0.078 inch limit applies to every surface from collar to fan, including a riser that climbs past residential floors. The standard is explained on the NFPA 96 page, and bookings go through the contact page.
