Bathroom and kitchen exhaust fans accumulate dust, lint, and grease over time — restricting airflow, trapping moisture in your home, and in the case of kitchen exhausts, creating a genuine fire hazard. Universal Duct Cleaning provides professional washroom and kitchen exhaust cleaning for homeowners across Toronto and the GTA, restoring proper ventilation and helping protect your home from mold, moisture damage, and grease buildup.
Exhaust fans are one of the most overlooked components in a home’s ventilation system. In bathrooms, a partially blocked fan can’t remove humid air fast enough, leading to persistent condensation and mold growth on walls and ceilings. In kitchens, grease accumulation in the range hood and exhaust duct creates a real fire risk over time. Universal Duct Cleaning cleans the full exhaust path — from the fan grille to the exterior vent cap — for both washrooms and kitchens across Toronto and the GTA.
If your bathroom mirror and surfaces stay foggy long after the shower is off, the exhaust fan likely isn't moving enough air to clear the moisture properly.
A kitchen exhaust fan clogged with grease loses its ability to remove cooking odours and smoke effectively, leaving them lingering throughout the home.
Fans that vibrate, make unusual sounds, or run slower than they used to often have dust or debris buildup affecting the motor or impeller blades.
Visible mold growing near the exhaust grille or on the surrounding ceiling is a direct sign the fan isn't adequately ventilating moisture out of the space.
Grease deposits visible on the range hood filters or interior surfaces indicate the duct behind it may be coated with grease — a fire hazard that needs to be addressed.
Bathroom exhaust fans should be professionally cleaned every 1–2 years. Kitchen range hood ducts need attention even more frequently in homes where cooking is heavy.
The exhaust fan cover and grille are removed and thoroughly cleaned of dust, lint, and grease buildup before reassembly.
The fan impeller blades and motor housing are cleaned to remove debris that reduces rotation speed and airflow output.
The duct connecting each fan to the exterior vent is cleared of accumulated lint, dust, and grease from end to end.
The exterior vent flap is inspected and cleared to ensure air is exhausting freely outside the building without restriction.
Kitchen range hood grease traps and filters are cleaned as part of the kitchen exhaust service, removing accumulated grease from both the visible and hidden surfaces.
All components are reassembled and each fan is tested to confirm proper operation and adequate airflow before we leave.
We inspect each exhaust fan, its duct run length and condition, and the exterior vent cap before beginning any cleaning.
The grille, cover, blades, and housing are removed and cleaned of all accumulated dust, lint, and grease.
The internal duct connecting the fan to the exterior is cleaned from the fan housing to the exterior vent opening.
The exterior vent flap is inspected to confirm it opens freely and closes properly to prevent pest entry and backdrafts.
All components are reinstalled and each fan is tested to verify proper airflow before we complete the service.
We recommend professional cleaning every 1–2 years for bathroom exhaust fans. Kitchen range hood ducts should be cleaned more frequently — annually in homes where cooking is regular.
Yes. When a bathroom exhaust fan can't adequately remove humid air, moisture accumulates on walls, ceilings, and fixtures — creating the conditions mold needs to grow.
Yes. Accumulated grease in kitchen exhaust ductwork is a real fire hazard. In the event of a stovetop fire, a grease-lined duct can allow flames to travel rapidly through the wall cavity.
Yes. We clean the full duct run from the fan housing to the exterior vent opening, not just the visible grille and cover.
Each individual exhaust fan typically takes 30–60 minutes. A full-home service covering multiple bathrooms and a kitchen exhaust usually takes 2–3 hours depending on the number of fans and duct lengths involved.
