The Hidden Fire Risk Lurking Over Your Fryer: Why Professional Hood & Vent Cleaning Matters
In every commercial kitchen, the heartbeat of daily operations lies beneath the surface; inside the exhaust hood and ventilation system. What was once an afterthought in restaurant design has evolved into one of the most highly regulated, safety-critical components of any food-service operation.

Hood and vent cleaning: The process of removing built-up grease, vapours, and carbonized residue from a kitchen’s exhaust infrastructure, emerged as a distinct trade in the mid-20th century. As kitchens scaled up and ventilation systems became more powerful, so too did the risks. Grease buildup inside ducts and fans became a known fire hazard, and regulators responded.
Today, every commercial kitchen in Ontario is subject to fire codes, insurance rules, and public health inspections that require exhaust systems to be cleaned by trained professionals on schedule, with documentation.
What exactly is hood & vent cleaning?
Hood & vent cleaning refers to the thorough removal of grease, smoke residue, and flammable buildup from an entire commercial kitchen exhaust system. This includes:
- The hood over the cooking line
- Baffle filters, UV bulbs, and lighting inside the hood
- The internal ductwork through ceilings and walls
- Exhaust fans and grease containment systems on the rooftop
- Drainage trays, fan blades, and mechanical components
In Northern Ontario cities like Sudbury, Timmins, Sault Ste. Marie, North Bay, and Barrie, local fire departments have the authority to shut down kitchens that don’t meet required cleaning and documentation standards. And yes, we’ve seen it happen. Often.
The risk is real. But it’s avoidable with the right service partner.
Local bylaws & compliance: What you need to know in Northern Ontario
Commercial kitchens across Northern Ontario are subject to stringent municipal bylaws and property standards regulations. Non-compliance can lead to fines, operational shutdowns, or insurance complications. Here's a breakdown of key regulations in the cities we serve:
Sudbury
Under the Property Standards By-law 2011-277, the City of Greater Sudbury mandates that all commercial properties, including restaurants, maintain their premises in a condition that does not pose a risk to health or safety. This includes the proper maintenance and cleanliness of kitchen exhaust systems to prevent fire hazards.

Why not do it yourself?
We get it, nobody wants to spend money if they think they can tackle it themselves. But cleaning a commercial exhaust system isn’t like cleaning your stovetop at home.
Most business owners quickly realize:
- It’s physically demanding, dirty, and takes hours
- Rooftop systems are hard to access and can be dangerous
- Common degreasers don’t work on carbonized grease or damage metals
- Documentation and inspection-ready reports are required by insurers and bylaw officers
And frankly? Most people don’t want to do it. It’s a burden. That’s why Reliable exists; to take this off your shoulders so you can focus on your business.
