Exhaust Fan Installation and Kitchen Exhaust Fan Repair in Niagara Falls
Exhaust Fan Repair and Installation in Niagara Falls is the rooftop service that keeps a commercial kitchen exhaust fan pulling air out of the building. It covers belt, bearing and motor replacement, a new fan when the old housing is finished, a hinge kit so the fan tips open for cleaning, and grease containment that protects the roof. Niagara Falls Hood Cleaning inspects the fan on its curb, photographs what it finds and quotes each job on its own. The written quote comes back within 24 hours.
Rooftop exhaust fan anatomy: belt, bearings, motor and curb
Most rooftop kitchen exhaust fans are upblast fans. They sit on the roof and throw the exhaust straight up, away from the membrane. When the fan slows or stops, the hood below loses its draw and the kitchen fills with smoke. Four parts cause most failures.
The belt links the motor to the fan wheel. It stretches, glazes and slips, and a slipping belt squeals and turns the wheel too slowly.
The bearings hold the fan shaft. Grease and heat dry them out, and a worn bearing growls, runs hot and lets the wheel wobble.
The motor drives the whole system. It fails from heat, moisture and grease that coats its cooling fins.
The curb is the raised frame the fan sits on, sealed into the roof. A rotted or loose curb lets water into the building and lets the fan shift in the wind.
Kitchen exhaust fan repair vs replacement in Niagara Falls
The condition of the housing and the motor decides whether a repair is money well spent.
| What the inspection finds | Repair vs replace |
|---|---|
| Squeal at start-up, glazed or cracked belt | Repair. A new belt, tensioned and aligned with the pulleys. |
| Growling, heat at the shaft, wheel wobble | Repair. New bearings, as long as the shaft is not scored. |
| Motor trips, hums without turning, or burns out | Repair with a new motor if the housing and wheel are sound. Replace if they are not. |
| Cracked wheel, rusted-through housing, grease-soaked insulation | Replace. A new fan, sized to the hood and duct, on the existing curb where it fits. |
| New cooking line, larger hood, or a kitchen fit-out | Install. A new fan and curb matched to the new hood. |

Exhaust fan hinge kit: why a bolted fan never gets cleaned
An exhaust fan hinge kit is a set of heavy hinges and a retaining cable fitted between the fan base and the curb, so one technician can tip the fan back and reach inside.
A fan bolted straight to its curb has to be unbolted and lifted to reach the wheel, the housing and the top of the duct. That takes two people and risks the curb seal, so on many roofs it simply does not happen. Grease then builds on the wheel, throws it out of balance and wears out the bearings.
A hinge kit turns fan cleaning into a routine part of every full-system visit. On installation, the fan is lifted, the hinge plates are fixed to the base and the curb, the cable is set to stop the fan at a safe angle, and the fan is lowered back onto a fresh seal.
Rooftop grease containment: the roof membrane, the landlord and the plaza
Rooftop grease containment is a trap or absorbent unit fitted under the fan drain so grease lands in the trap, not on the roof.
Every upblast fan drips grease from its drain spout. On a flat roof, that grease spreads out, softens the roof membrane and breaks it down. The result is leaks into the unit below and a slick patch that is a slip hazard and a fire risk on the roof itself.
In a plaza, the roof belongs to the landlord, but the grease comes from your kitchen. A property manager who finds a stained membrane will often send the repair bill to the tenant. Containment is the cheapest way to avoid that argument. The quote lists fan work and containment as roof items, so the owner and the tenant can agree who approves them.
Kitchen exhaust fan repair in Niagara Falls: lake-effect wind and freeze-thaw on the roof
Niagara roofs sit between Lake Ontario and Lake Erie, and that weather is hard on a rooftop fan.
Wind off the lakes pushes against the fan hood and loosens a tired curb. Winter brings repeated freeze and thaw cycles, which open cracks in the curb seal and let water run down the outside of the duct. Wet motors fail sooner. A fan that sat idle through a quiet February in a Clifton Hill kitchen can seize when the spring rush starts. A spring inspection before the summer season catches a worn belt or a dry bearing before it fails in July. Roofs in Port Colborne and Wainfleet on Lake Erie and in Niagara-on-the-Lake near Lake Ontario take the most wind.

Exhaust fan repair and installation in Niagara Falls: frequently asked questions
How do I know my exhaust fan is failing?
Warning signs are a squeal at start-up, a growl or rattle from the roof, a burning smell, and smoke that the hood stops pulling away. Any of these calls for a roof inspection before the fan stops.
Can the fan be repaired during a cleaning visit?
Belts and bearings can usually be replaced on the same visit if the parts are known in advance. The walk-through identifies the fan model so the parts come with the crew.
Do I need a hinge kit?
A hinge kit is worth fitting if your fan is bolted to its curb with no way to tip it open. Without one, the wheel and housing tend to be skipped, and the grease inside them is still part of the system.
Who pays for rooftop grease damage in a leased unit?
Your lease decides that. Many property managers charge the tenant whose kitchen feeds the fan, which is why a containment unit usually costs less than a membrane repair.
Can you install an exhaust fan for a new restaurant?
New fan installation is part of this service. The fan is sized to the hood and duct, set on a sealed curb with a hinge kit and containment, and quoted per job. The restaurant hood cleaning page covers what a restaurant needs after it opens.
