When we performed a recent job, we removed 5 inches of compacted lint from a dryer exhaust line yes, five inches. That’s an extreme build-up, and scenes like this are more common than most homeowners realize. This level of lint accumulation drastically restricts airflow, making dryers work harder, run hotter, and become serious fire risks.
Why 5 Inches of Lint Matters
Lint is highly flammable. According to the NFPA, lint, fiber, and dust are responsible for around 26% of dryer fires. NFPA+1 In fact, there are over 15,000 dryer-related house fires annually in the U.S., causing more than $84 million in property damage. National Park Service+1 When clogged vents severely reduce airflow, heat builds up inside the vent and the lint itself can ignite.
One Neighbor’s Clog Can Endanger Everyone
In multi-unit buildings or adjacent homes, a clogged dryer exhaust in one unit can back up air pressure or even push lint & heat into shared ductwork. That means your neighbor’s vent issue might threaten your safety too. These cross-contamination or backflow effects pose both fire and air quality hazards for the entire building.
Key Risks from Severe Lint Buildup

Fire hazard: Lint is tinder when heated.
-
Poor drying performance: Your dryer may take multiple cycles to dry clothes.
-
Energy waste: Blocked vents increase energy consumption and utility bills.
