Clogged dryer vent — Delft, South Holland

A dryer vent clogged with lint, debris, or crushed ductwork is one of the most overlooked fire hazards in a home. The U.S. Fire Administration reports that dryer fires cause an estimated 2,900 residential fires each year, and failure to clean the vent is the leading cause. When the exhaust path is restricted, moist hot air cannot escape efficiently, forcing the dryer to run longer cycles while the internal temperature climbs to dangerous levels. Lint — which is highly flammable — accumulates inside the duct, at elbows, and at the exterior vent hood where it can ignite. Beyond fire risk, a clogged vent dramatically reduces dryer efficiency, increases energy costs, shortens appliance lifespan, and can push excess humidity into walls, encouraging mold growth. A handyman or vent-cleaning specialist will disconnect the dryer, use a rotary brush and high-powered vacuum to clear the entire duct run from the dryer collar to the exterior termination, inspect the vent hood flap for damage, and verify proper airflow with an anemometer.
