Kitchen Exhaust Cleaning in Bradford
Bradford Hood Cleaning Pros is a commercial kitchen exhaust cleaning contractor working the full duct path behind the hood: the horizontal run above the ceiling, every elbow and transition in it, the vertical riser, and the access panels that make those sections reachable. Each section is cleaned in turn, code-compliant panels are cut in where a run cannot otherwise be opened, and every section is named on the certificate. Single-hood kitchens in Bradford, Newmarket and Aurora start from $385 per visit.
The duct is where the fire risk lives, and where most cleaning stops
Grease that gets past the filters condenses along the duct as the air cools, so the run carries a heavier deposit than the canopy that everyone can see.
Air leaves a cook line hot and loaded with vapour. It cools as it travels, and cooling is what turns vapour into deposit. That means the load is not distributed evenly along the run. It concentrates where the air slows and changes direction: the first elbow after the hood collar, any transition where the duct changes size, and the base of the vertical riser where horizontal flow turns upward.
Those are also the three places hardest to reach, which is how a system ends up with a spotless canopy and a duct nobody has opened. A cleaning that stops at the plenum has cleaned the part with the lowest deposit and left the part with the highest.
Access panels: the item most quotes leave out
A duct section with no access panel cannot be cleaned or inspected, so panel installation is priced in the written quote rather than discovered on the night.
NFPA 96 expects the whole grease-carrying path to be reachable. In practice, a great many kitchens in Bradford, Newmarket and Aurora were fitted into existing buildings, and the duct was routed around whatever was in the way and then boxed in. Nobody planned for someone opening it years later.
The tell is a quote that names the canopy, the filters and the fan but says nothing about the run between them. That is not necessarily dishonest. It is often a quote written from a phone description by someone who has not seen the ceiling. But it means the price will change, or the run will be skipped, and skipping it is the outcome that carries risk forward invisibly.
Panels get cut in where they are needed, positioned so the run can be reached properly rather than just technically, and they stay in place for every future visit. It is a one-time cost on a system that was never built for maintenance, and it is the difference between a certificate that means something and one that covers whatever happened to be accessible.
Horizontal run vs vertical riser: why they clean differently
A horizontal run collects deposit along its floor and is cleaned through panels, while a riser sheds deposit downward and is cleaned from the fan opening above.
| Section | Where deposit sits | How it is reached | The usual problem |
|---|---|---|---|
| Horizontal run | Along the bottom face, heaviest near the hood collar and at each elbow. | Through access panels at intervals along the run, worked in both directions from each opening. | The run is above a finished ceiling with no panels, so nobody has opened it since installation. |
| Elbows and transitions | On the outer radius, where air slows through the turn. | A panel at or immediately beside the turn. Reaching an elbow from a distant panel does not work. | Heaviest deposit in the system and the section most often reported as clean without being opened. |
| Vertical riser | On the walls, with heavier accumulation at the base where the turn upward happens. | From the fan opening at the top, working down, which is why a hinged fan matters so much. | A bolted-down fan that nobody can lift, leaving the riser cleaned by reach rather than by sight. |
| Shared riser, multi-tenant | Combined load from every tenant on the stack. | From the fan, with coordination across tenants so the whole stack is done at once. | Each tenant cleans their own branch and assumes someone else handles the shared section. Usually nobody does. |
The shared riser is the one worth raising with a landlord before it becomes a dispute. It is covered further on the rooftop grease containment page, and the access question is solved by the fan hinge kit.
How much does kitchen exhaust cleaning cost in Bradford in 2026?
Bradford Hood Cleaning Pros quotes from $385 per visit for a single-hood system, with duct length, elbow count and existing access the variables that move it.
Two kitchens with the same canopy can differ substantially once the run is measured. A short straight riser from a rear-wall hood to a fan directly above is the cheapest configuration in the trade. A run travelling twenty feet above a dropped ceiling with three elbows and no existing panels is several times the labour, most of it spent creating access rather than cleaning.
That is why the walk-through exists and why it is free. It puts a real number on the actual system instead of a range on a typical one. Multi-hood kitchens start from $725 per visit, and institutional and multi-tenant systems are quoted on site.
Every visit ends with before-and-after photographs of each section, a signed certificate referencing the published NFPA 96 standard, and proof of WSIB and liability coverage supplied before work starts. The cost guide breaks the pricing down further, and the standard itself is explained on the NFPA 96 page.
Next step: call 365-809-0864 or request a written quote. Say what you cook, roughly where the roof fan sits relative to the hood, and whether anyone has ever opened a duct panel. The walk-through settles the rest.
Kitchen exhaust cleaning: frequently asked questions
What operators ask about the part of the system they cannot see.
How do I know whether my duct has actually been cleaned?
Ask for photographs taken inside the run, not of the canopy. A contractor who opened the duct can show you the inside of it before and after, at each panel. One who did not, cannot. This is the single most useful question an operator can ask, because the duct is the part that carries the fire risk and the part nobody can check from the floor.
Does cutting an access panel damage the duct?
No, when it is done properly. A code-compliant access panel is a purpose-made, gasketed and labelled opening fitted so the duct remains sealed and continues to perform as designed. NFPA 96 expects the grease-carrying path to be reachable, so a duct with proper panels is closer to compliant than one without. What does cause damage is an improvised opening cut and patched with sheet metal and sealant.
My building is multi-tenant with a shared riser. Who cleans it?
In practice it is whoever the landlord contracts, and the failure mode is that nobody does. Each tenant cleans their own branch and assumes the shared vertical section is somebody else's. The workable arrangement is one contract covering the shared riser and the rooftop fan, coordinated so the whole stack is cleaned at once, with the photo record going to the property file rather than to one tenant's back office.
How long does a duct clean take?
A single-hood kitchen with a short run is typically one overnight visit. A long run with multiple elbows, or a system needing access panels cut in, can take longer, and where panels are being installed the work is sometimes split so the kitchen is never down for a service. The walk-through gives a realistic duration rather than an optimistic one, and it is stated in the written quote.
Can the duct be cleaned without shutting the kitchen?
The work happens overnight or between service hours, so the kitchen does not lose a shift. The cook line does need to be cold and clear, since panels are being opened above it and grease is being removed rather than pushed around. In occupied buildings such as retirement residences the visit is planned around meal services at the walk-through stage.
