This Is What a Clogged Dryer Vent Actually Looks Like

Most homeowners never think about their dryer vent. You clean the lint trap after every load - great. But that lint trap only catches a fraction of what actually makes its way into the vent system. The rest keeps building up, load after load, year after year, until airflow is almost completely cut off.

That's exactly what we were dealing with on this job. The vent was routed through the roof - which is common - but the cap and the duct interior were packed solid. We're talking dense, matted lint caked along every surface inside the duct. The kind of buildup that doesn't happen overnight. It takes time, and it almost always goes unnoticed until something goes wrong.

Here's why that matters. A blocked dryer vent is one of the leading causes of house fires. Lint is highly flammable, and when it's sitting inside a hot duct with restricted airflow, the conditions are there. Beyond the fire risk, a clogged vent means your dryer is working twice as hard to push moisture out. Clothes take longer to dry. Energy bills creep up. The dryer wears out faster.

Once we cleared the duct and pulled the roof cap, the difference was immediate. Airflow was fully restored, the duct walls were clean, and the cap flap was operating the way it should - opening freely to let air out and closing to keep pests and weather from getting in. Clean metal, no obstructions.

If your dryer has been running longer than usual, or your clothes are coming out damp after a full cycle, the vent is almost always the first place to look. A professional dryer vent cleaning is one of the easiest maintenance jobs you can do for your home - and one of the most overlooked.
