Fire Prevention Cleaning and Degreasing in Toronto
Fire prevention cleaning and degreasing is the removal of grease film from the kitchen surfaces the exhaust system does not cover: the walls behind and beside the cook line, the ceiling above it, backsplashes, and the shelving and fixtures within reach of cooking vapour. Hood Cleaning Toronto strips that film with food-area-rated degreasers, photographs every surface before and after, and schedules the work overnight or between services across the City of Toronto. Grease that settles a metre from the hood is the same fuel as grease inside it; the only difference is that nobody certifies its removal unless this service is booked.
Why grease off the hood still burns
A hood captures most cooking vapour. The fraction that escapes settles somewhere, every shift, and it never stops accumulating on its own.
No exhaust hood captures everything. Vapour rolls off the canopy lip when a fryer surges or a pan flares, drifts when a door opens and the air balance shifts, and rises past the hood edge from equipment parked slightly outside its footprint. That escaped vapour cools and condenses as a thin film on the nearest cool surface: paint, tile, stainless trim, ceiling panels. One shift deposits nothing you can see. A year deposits a coating that yellows the paint, tacks up under a fingertip, and holds dust and flour against the wall.
That film is fuel with a large surface area. In a kitchen fire, flame spreads along coated surfaces far faster than along clean ones, and a greasy ceiling turns a contained flare-up on the line into a room-level event. Fire investigators trace spread along exactly these films, and insurers know it, which is why questions about kitchen cleaning after a claim rarely stop at the hood certificate.
The exhaust system itself, from canopy to rooftop fan, is a separate scope covered on the kitchen exhaust cleaning page. Degreasing is what happens to the room around that system.
Where does grease settle beyond the hood in a Toronto kitchen?
Grease settles heaviest on the wall directly behind the cook line, the ceiling within a few metres of the hood, backsplashes at splatter height, and the tops of anything mounted near cooking.
The pattern is predictable because it follows the air. The back wall takes direct splatter plus condensed vapour and is usually the heaviest surface in the room. The ceiling above and just beyond the hood collects the plume that escapes capture, and porous ceiling tiles absorb it permanently. Backsplashes take the hot splatter zone between equipment and wall. High surfaces, including shelf tops, the upper sides of wall cabinets, conduit runs, and the top edges of doorframes, gather a film nobody sees from the floor but every fire and every thorough inspection finds.
Older Toronto kitchens compound it. Decades of repainting over grease leaves layered, soft coatings that a casual wash smears rather than removes. Degreasing strips back to a sound surface, and where paint has failed under the film, the report says so, which gives an operator a real maintenance picture instead of a cosmetic one.
Degreasing vs exhaust cleaning: which surfaces each covers
The two scopes divide at the hood edge. Together they cover every greased surface in the kitchen; separately each leaves the other half untouched.
| Surface | Fire prevention degreasing | Exhaust cleaning |
|---|---|---|
| Walls behind and beside the cook line | Yes, stripped to a sound surface. | No. |
| Ceilings and ceiling tiles near cooking | Yes, cleaned or flagged for replacement. | No. |
| Backsplashes and wall trim | Yes. | No. |
| Shelf tops, fixtures, conduit near the line | Yes. | No. |
| Hood canopy, filters, plenum | No. | Yes. |
| Ducts, exhaust fan, rooftop | No. | Yes, on a full-system clean. |
| Cooking appliances themselves | No, that is equipment cleaning. | No. |
The appliance scope in the last row is covered on the restaurant equipment cleaning page. Kitchens booking all three get one coordinated overnight visit and one photo record.
How much does fire prevention degreasing cost in Toronto?
Hood Cleaning Toronto quotes degreasing in writing per kitchen, and most operators book it with a hood cleaning visit, which starts from $385 for a single hood and from $725 for multi-hood kitchens, with full pricing detail on the hood cleaning cost guide.
Scope drives the number: how many square metres of wall and ceiling, how heavy and how old the film, and how much of the kitchen needs masking to protect it. Kitchens with high-volume lines, like the ones described on the restaurant hood cleaning page, generally pair degreasing with their exhaust schedule; how often the exhaust side itself must be cleaned is set by the published NFPA 96 frequency categories laid out on the regulations and NFPA 96 guide.
Fire prevention degreasing in Toronto: frequently asked questions
Which surfaces are included in a fire prevention degreasing visit?
The written scope lists them per kitchen, and it typically covers the walls behind and beside the cook line, the ceiling area near the hood, backsplashes, and grease-coated fixtures and shelf tops adjacent to cooking. Hood Cleaning Toronto walks the kitchen first, marks the surfaces carrying film, and puts each one in the quote so the after-photos can be checked against a list rather than a guess.
Will degreasing damage painted walls or stainless finishes?
Sound paint and stainless steel handle food-area-rated degreasers without damage, and the crew tests a small area first on anything questionable. Where paint is already failing underneath the grease film, the film is what has been holding it together, and stripping it exposes the failure rather than causing it. That gets photographed and reported so the operator knows a repaint is due.
What happens with grease-soaked ceiling tiles?
Cleanable ceiling panels, such as vinyl-faced or metal tiles, are degreased in place. Porous fibre tiles that have absorbed grease cannot be cleaned back to safe condition, so the visit report identifies them for replacement instead of wiping their surface and leaving the fuel inside the tile. The photos show exactly which tiles fall into which category.
Does the kitchen need to be emptied before a degreasing visit?
No. The crew masks and sheets equipment, shelving contents, and open food areas near the work, and moves only what sits directly against the surfaces being cleaned. Clearing loose items off the affected shelving and wall racks ahead of time speeds the visit up, but the kitchen does not need to be packed up or shut down beyond the overnight window itself.
Can degreasing be split across more than one night?
Yes. Larger kitchens are staged by zone so each overnight window ends with that zone rinsed, dried, unmasked, and ready to work in the next morning. Nothing is left half-stripped between visits, and the photo record is delivered per zone so a manager can track exactly which sections are done at any point in the schedule.
