Mississauga homeowner checklist
Before the appointment
Clear laundry products from the appliance area and make a path to the dryer. If the vent exits above grade, on a balcony or through a roof, share that in advance so the provider can confirm suitable access.
Watch the exterior outlet
When it is safe to do so, observe whether the outside flap opens while the dryer runs. A flap that does not move can point to a restriction, damaged connection or stuck termination—but it is not a substitute for an inspection.
Use official maintenance guidance
Toronto Fire Services recommends regularly removing lint from metal ducts and exhaust vents and inspecting the outdoor flap. Natural Resources Canada also advises regular vent cleaning to improve airflow and reduce strain on the dryer.
