Dryer Ducts Sealed Tight? That’s a Ticking Fire Hazard You Never Saw Coming Your home’s dryer ductwork plays a crucial role in safely venting hot exhaust, moisture, and lint from your clothes dryer. But sealing dryer ducts too tightly—or improperly—can create a silent, dangerous fire hazard that quietly builds up until it becomes life-threatening. If your dryer ducts are sealed tightly without proper ventilation or safety measures, you may be ignoring one of the most overlooked home fire risks. ### Why Sealed Dryer Ducts Are Dangerous When dryer ducts are sealed too tightly, airflow is restricted. This forces the dryer to work harder, increasing strain on the motor and components. More critically, lint—a highly flammable material—builds up inside the ducts over time. Since lint accumulates in crevices and narrow spaces, sealed ducts trap this combustible debris, forming thick, ignitable clumps.
