Your first NFPA 96 inspection in Milton or Halton Hills
Milton Hood Cleaning is the guide a first-time Milton or Halton Hills kitchen operator needs before a fire inspector asks about NFPA 96. The standard, published by the National Fire Protection Association, governs grease in the exhaust path: how much is allowed to build up before it becomes a fire hazard, how often each kitchen type gets checked for it, and what record proves the checking happened. The Ontario Fire Code adopts NFPA 96 as its technical reference, so an inspector in either town measures your system against the same numbers. Milton Hood Cleaning references the published NFPA 96 standard and carries no affiliation with NFPA.

The three things an inspector checks against
Strip away the paperwork and NFPA 96 comes down to three questions a fire inspector asks in order.
How much grease is on the surfaces right now? The standard puts a number on it: 0.078 inches. A technician runs a depth gauge across the plenum wall, the inside of the duct and the fan housing, and anything that measures at or past that mark is scheduled for cleaning.
Is the kitchen on the correct schedule? NFPA 96 does not treat every kitchen the same. It sorts operations into four bands, running monthly to annual, based on what and how much the kitchen cooks.
Can the last visit be proven? A dated record naming which sections were opened, what the technician found and who performed the work. A Milton kitchen in a plaza that has never had that record started has nothing to hand the inspector yet: the hood cleaning services page covers what the first visit establishes.
Which interval applies to a Milton or Halton Hills kitchen?
Four bands, sorted by cooking type and volume rather than square footage: monthly for anything solid-fuel, quarterly for high-volume cooking such as charbroiling or wok work, semi-annual for a standard single- or two-shift kitchen, and annual for a low-volume or seasonal operation. Whichever band a system lands in, cleaning is triggered once the grease reading reaches 0.078 inches, so a kitchen can sit inside its interval and still need an earlier visit.
| Interval vs cooking type | What lands in this band | A kitchen in Milton or Halton Hills it describes |
|---|---|---|
| Monthly | Any wood, charcoal or pellet cooking, regardless of volume | A wood-fired oven on downtown Milton's Main Street, or a smoker vendor at the Milton Fall Fair. |
| Quarterly | Charbroiling, wok cooking, or a line that runs 24 hours | A charbroiler in a new plaza kitchen off Derry Road, or a wok station on Georgetown's Main Street. |
| Semi-annual | A regular single- or two-shift kitchen with no charbroiling or wok cooking | A weekday-only staff cafeteria inside the Derry Green Business Park. |
| Annual | Churches, day camps and businesses that run seasonally | A church hall kitchen in Acton, or a concession stand that opens near Kelso Conservation Area for summer only. |
These bands are the floor, not a fixed schedule. Add a charbroiler, extend the hours, or pick up a wood-fired item, and the kitchen moves to the shorter interval that matches its new menu.
NFPA 96 sets the number, the Ontario Fire Code makes it enforceable
Operators sometimes ask which one they actually have to follow. The answer is both, and they do different jobs. The Ontario Fire Code is the law that an inspector in Milton or Halton Hills acts under, and it points to NFPA 96 for the technical detail: the grease depth, the interval bands and what a clean record has to show. Take away the Fire Code and NFPA 96 is only a published standard with nothing to enforce it. Take away NFPA 96 and the Fire Code has no measurement to check a kitchen against.
Neither document names a contractor or hands out a license. What each part of the system needs done is covered on the hood cleaning services, kitchen exhaust cleaning and exhaust fan repair and installation pages.
Two inspectors, two clipboards: what each one actually checks
A Milton or Halton Hills kitchen answers to more than one inspector, and mixing up their checklists is the most common surprise for a first-time operator. Milton Fire and Rescue Services covers the Town of Milton, Campbellville included. Halton Hills Fire Department covers Georgetown, Acton and the surrounding hamlets. Halton Region Public Health inspects food premises across both towns under its Dinewise program. Three separate agencies, two separate kinds of inspection.
What the fire inspector wants to see. The most recent cleaning record, then a walk of the system to confirm it matches. If the record only mentions the canopy, expect a question about whether the duct and the rooftop fan were opened too. A fan bolted shut, missing access panels, or gaps in the dated history are the findings that come up most.
What the public health inspector wants to see. Food handling, temperature control, sanitation and pest activity, disclosed publicly through Dinewise with a posted Certificate of Inspection. Grease inside the exhaust system is not part of that checklist. A spotless Dinewise result tells you nothing about what the depth gauge would find in the duct.
Two binders, two questions, and neither inspector substitutes for the other. What each kitchen type in Milton and Halton Hills tends to run into is broken down further on the who we serve page.
What the certificate on your wall actually proves
A hood cleaning certificate is a signed statement from the contractor, tied to one exhaust system on one date, describing what was cleaned with reference to the published NFPA 96 standard.
It proves the named sections cleaned, the date of the visit, the grease depth measured, and who signed off, backed by before-and-after photographs of every surface that was touched. That is the version Milton Hood Cleaning issues after a visit.
It does not prove that the kitchen passed a fire inspection, that a suppression system was tested, or that any section left off the certificate was ever opened. A certificate marked "canopy only" is exactly that: canopy only. It also does not turn the contractor into an NFPA-approved company, since NFPA writes standards and does not certify or approve anyone who cleans to them.
Is a company "NFPA 96 certified"? No, and here is why
Ask around Milton or Halton Hills and you will hear "NFPA 96 certified technicians" as a selling point. It is not a real credential. NFPA does not run a certification program for contractors, the Ontario Fire Code does not license hood cleaners, and neither Milton Fire and Rescue Services nor Halton Hills Fire Department puts its name behind a company.
What you can actually ask for, and what any legitimate contractor should hand over before the truck shows up:
- A signed certificate naming every section cleaned and referencing the published NFPA 96 standard.
- Before-and-after photographs covering the duct interior and fan housing, not just the parts visible from the kitchen floor.
- Proof of WSIB coverage and liability insurance, supplied before the work starts, covering anyone the contractor puts on your roof.
If a contractor's pitch leans on the word "certified" but nothing on that list shows up, that is the gap worth asking about.
Before the next inspection lands on the calendar
A free walk-through checks the plenum, duct and fan against the 0.078 inch limit and tells you which interval band the kitchen sits in. A single-hood kitchen up to ten feet is cleaned from $585 per visit; a larger system is priced on site after that walk-through.
Call 289-401-1377 or request a written quote, and it lands in your inbox within 24 hours. Bring the last certificate along if one exists, even an old one.
NFPA 96 in Milton and Halton Hills: frequently asked questions
Does a food truck at the Milton Fall Fair fall under NFPA 96?
Yes. NFPA 96 covers any commercial cooking setup that produces grease-laden vapour, and a food truck's hood counts. The truck lands on whichever interval its cooking style earns in a fixed building.
Did NFPA 96 change for 2026?
The four interval bands and the 0.078 inch grease depth are unchanged from the previous edition. What moves a kitchen between bands is its own operation: a new appliance, longer hours or a menu shift, so it is worth rechecking against the current setup each year.
Is a hood cleaning certificate the same document as a Dinewise Certificate of Inspection?
No. The hood cleaning certificate is the contractor's exhaust-system record, used by the fire service. The Dinewise Certificate of Inspection comes from Halton Region Public Health after a food safety inspection. One does not stand in for the other.
Who inspects a kitchen in Campbellville or one of the Halton Hills hamlets?
Campbellville falls inside the Town of Milton, so Milton Fire and Rescue Services handles Fire Code enforcement there. Halton Hills Fire Department covers Georgetown, Acton and the hamlets around them.
Does NFPA 96 apply to a range hood in a home kitchen?
No. The standard is written for commercial cooking operations. Milton Hood Cleaning works on commercial kitchens only and does not service home range hoods.
