Commercial Hood Cleaning in Barrie
Commercial hood cleaning is the mechanical removal of cooking grease from the hood assembly over a cook line: the canopy interior, the baffle filter bank, the filter seat and grease trough beneath it, and the plenum cavity behind the filters. Barrie Hood Cleaning scrapes and hot-degreases each of those surfaces back to bare stainless, photographs every one before and after, and ends the visit with a signed certificate referencing the published NFPA 96 standard that the Ontario Fire Code adopts by reference.
What a commercial hood cleaning actually removes
The canopy interior is the sloped stainless hanging over the fryers and the flat top, and it is the part a line cook degreases at close. The baffle filter bank sits angled in its throat. The filter seat is the channel the baffles drop into, with the grease trough and its removable cup along the bottom. The plenum cavity is the void behind the filters where the airstream turns and slows into the duct collar, which is why the plenum, not the canopy, is normally the dirtiest square foot in the assembly.
The published NFPA 96 standard sets one number for all of it: a grease deposit may not exceed 0.078 inches on any surface in the exhaust path. No allowance lets the plenum carry more because nobody sees it. A cleaning that stops at the visible canopy face leaves the two surfaces most likely to fail untouched, which is why Barrie Hood Cleaning pulls the filter bank on every visit.
Scraping back to bare stainless is a sequence, not a spray. Filters come out and go to soak. A hot alkaline degreaser dwells on the canopy, seat, trough, and plenum so it softens the varnished layer instead of smearing it. The deposit is scraped off the flats, corners, and seam welds by hand, everything is rinsed and dried, and each cleaned surface is photographed from its original angle.
Wipe-down vs NFPA 96 hood cleaning: what an inspector accepts
Only one survives a flashlight behind the filter bank.
| Surface | Kitchen wipe-down | NFPA 96 hood cleaning | What the inspector accepts |
|---|---|---|---|
| Canopy face and underside | Degreaser and a cloth at close. Removes the fresh film, leaves the varnished layer in the corners. | Dwelled degreaser, hand-scraped flats, corners, and seam welds, rinsed and dried. | Bare stainless. A tacky brown film reads as deposit even where it measures thin. |
| Baffle filter bank | Rinsed in place or run through the dish machine still seated. | Pulled, soaked, drained free, inspected for warping and edge gaps, reinstalled facing the right way. | Baffles that drain, seat flush, and carry no bridging deposit between the vanes. |
| Filter seat and grease trough | Cup tipped out. The channel itself is rarely reachable with the filters in. | Channel scraped along its full length, trough and cup washed separately, drain path proven clear. | A trough that still drains. Standing grease in the channel is a straightforward finding. |
| Plenum cavity behind the filters | Not touched. A cloth cannot reach past a seated filter bank. | Filters out, cavity degreased and scraped to the duct collar, including the top corners. | This is where the flashlight goes first. Heavy plenum deposit fails the hood on its own. |
| Documentation | None. Nothing dated, nothing signed, nothing an insurer can read. | Before-and-after photos of each surface plus a signed certificate referencing NFPA 96. | Dated proof naming the surfaces cleaned. A verbal assurance is not evidence. |
Nightly wiping slows the build-up, but it is not a substitute for the scheduled cleaning and it produces no record. The NFPA 96 guide sets out what the standard requires in full.
How much does commercial hood cleaning cost in Barrie in 2026?
Barrie Hood Cleaning prices a single-hood commercial kitchen from $385 per visit and a multi-hood kitchen from $725, with golf and country club, campus, base, and multi-tenant kitchens quoted after a free walk-through. Every quote is written, arrives within 24 hours, and includes the photo report, the signed certificate, and proof of WSIB and liability coverage.
What moves the number is the assembly, not the postcode. Canopy length comes first: a ten-foot island canopy over a broiler carries more filter positions, trough, and plenum than a six-foot wall canopy. Next is the deposit already present, since a hood on a quarterly schedule cleans in a predictable window while one never scraped needs longer dwell and more hand work. Third is whether a ladder reaches the canopy without moving fixed equipment.
Deep-cleaning a neglected hood once is cheaper than an inspection finding plus a rushed reclean. A full breakdown sits on the hood cleaning cost guide. Call 705-413-1011 with your canopy length and cooking type and the written number comes back inside a day.
Why a clean-looking hood still fails an inspection
Barrie Hood Cleaning sees the same three findings on hoods the operator genuinely believed were clean, and all three sit behind or below the part that gets wiped.
Plenum build-up. The airstream turns as it enters the cavity, drops velocity, and lays down whatever it is still carrying. A canopy face polished every night sits two inches in front of a cavity nobody has opened.
A blocked grease trough. When the channel silts up, the baffles shed down the canopy instead, putting liquid grease on the outside of a hood that reads as maintained.
Seam and weld deposit. Grease grips harder on a rolled corner or a weld bead than on a flat panel, so a cloth pulled along a seam polishes either side and leaves a raised line down the middle. That line is what a gloved finger finds.
None of the three is negligence. They are the predictable result of the only cleaning a busy line can realistically do at midnight. The scheduled visit closes the gap and the photo set proves it. The duct and rooftop scope is covered by kitchen exhaust cleaning, and the filter bank by hood filter cleaning.
Where to book restaurant hood cleaning near me in Barrie
Barrie Hood Cleaning works the City of Barrie and Simcoe County on commercial kitchens only, and books the canopy work around service rather than through it.
Most hood-only work runs overnight for restaurants, which around Barrie means the Dunlop Street and Lakeshore Drive strip along Kempenfelt Bay, the Bayfield Street corridor, and the Allandale plazas. Club and banquet kitchens are booked between functions, and school and college serveries during March break or the summer term. The cook line is tarped before any degreaser is opened.
Residential range hoods are outside this service, because NFPA 96 governs commercial systems. County coverage and route days are on the areas served page, and the rest of the line-up on the commercial cleaning services page.
Commercial hood cleaning in Barrie: frequently asked questions
What counts as a clean hood under the 0.078 inch limit?
A hood is clean when no surface in the assembly carries a grease deposit thicker than 0.078 inches, the maximum the published NFPA 96 standard allows. That test applies to the plenum cavity and the filter seat exactly as it applies to the canopy face, so a hood can look finished from the cook line and still be over the limit two inches behind the baffle bank. Barrie Hood Cleaning scrapes each surface back to bare stainless, because bare metal is the only finish that photographs as unambiguously compliant.
Does commercial hood cleaning include the duct and the rooftop fan?
No. A commercial hood cleaning covers the hood assembly: canopy, baffle filters, filter seat and trough, and the plenum cavity. The horizontal duct run, the riser, and the rooftop fan are a separate scope handled by kitchen exhaust cleaning. Barrie Hood Cleaning names the surfaces cleaned on the certificate, so nobody discovers the difference during an inspection.
Can a hood be cleaned with the baffle filters left in place?
No, and a quote that allows for it is not a hood cleaning. The filters have to come out to reach the seat, the trough underneath, and the plenum cavity behind them, where the heaviest deposit usually sits. Barrie Hood Cleaning pulls every filter, cleans behind the bank, then reinstalls each one the right way around so the baffles drain into the trough.
What happens to a Barrie hood that has never been scraped back?
A hood that has only ever been wiped builds a hard varnished layer in the plenum and along the canopy seams that a cloth cannot lift. The first full cleaning takes longer, needs more dwell time, and occasionally exposes pitting or a failed seam hidden under the deposit. Barrie Hood Cleaning photographs whatever is found underneath and reports it in writing.
