Why the vent matters as much as the dryer
A clothes dryer pushes hot, moist, lint-laden air out of the house through a vent duct. The lint screen catches much of the lint, but not all of it. The rest settles along the inside of the duct, especially at bends, low spots and the exterior hood. As that layer grows, airflow drops, drying times stretch out and the dryer runs hotter than it should.
Fire safety agencies consistently identify failure to clean dryers and vents as a leading factor in home dryer fires. Lint is highly combustible, and a restricted vent traps heat around it. Cleaning the lint screen after every load is important, but it does not reach the lint that has already moved past it into the duct.
The lint screen catches what it can. The vent collects everything that gets past it.
Our cleaning covers the full length of the vent, not just the first few feet behind the dryer. We disconnect the transition duct, use rotary brushes and airflow tools suited to the duct size, and clear lint from the exterior hood. The dryer connection is then reattached securely so lint does not leak into the laundry room or wall cavity.
The inspection is as important as the cleaning. Many vents were installed with materials or routing that make clogging more likely. Plastic and thin foil transition ducts are not appropriate for dryer exhaust. Rigid or semi-rigid metal duct is the standard for most installations, with joints assembled in the direction of airflow and fastened in a way that does not leave screws protruding into the duct to catch lint. Maximum vent length depends on the dryer manufacturer instructions and the number of bends, so long runs deserve a closer look.
Exterior hoods cause their own problems. Screens over the opening trap lint and should not be used on dryer vents. Dampers can stick, nests can block openings, and hoods installed near the ground can be covered by snow or landscaping. We check that the damper opens freely when the dryer runs and closes when it stops.
Roof and long vertical vents are harder to maintain and often clog faster because lint has to travel upward. If routing changes would make the vent safer and easier to keep clean, we explain the options. For broader airflow and moisture concerns in the home, our Air Cleaning And Humidifiers page covers whole-house solutions.
Where the dryer sits matters too. Pushing a dryer tight against the wall can crush the transition duct behind it, cutting airflow even when the vent itself is clean. Recessed dryer vent boxes, periscope style connectors and careful positioning keep that connection open, and we point out when one of these would help in your laundry space.
We quote the cleaning at a flat rate before starting and tell you what we found, including any damaged sections or code concerns that need attention.
