Dryer vent cleaning removes the lint that collects inside the exhaust duct running from your clothes dryer to the outside of your home. Even with a clean lint screen, fine lint slips past every cycle and packs into the duct, its bends, and the exterior vent. That buildup traps heat and moisture, forces the dryer to run longer and hotter, and is one of the leading contributing factors in home dryer fires, according to the U.S. Fire Administration. This is a separate system from your chimney or fireplace flue, and it needs its own periodic cleaning to run safely and efficiently.
What dryer vent cleaning covers
The service clears the full exhaust path that moves hot air out of your dryer: the flexible transition hose behind the appliance, the rigid ductwork running through the wall, ceiling, or crawlspace, and the exterior vent hood where the air exits. A technician uses rotating brushes and vacuum equipment sized for the duct, then confirms the exhaust flap opens freely and air is moving strongly at the outside vent.
Lint screen cleaning between loads is your job and helps, but it only catches part of the lint. The rest is what a professional cleaning is designed to remove.
Signs your dryer vent needs cleaning
- Clothes take two cycles to dry or come out damp when a load used to finish in one.
- The dryer and laundry room feel hot during and after a cycle, and the top or sides radiate heat.
- A burning or musty smell when the dryer runs, which can mean lint is heating up inside the duct.
- The exterior vent flap barely moves or shows little airflow while the dryer is running.
- Lint appears around the outside vent or the dryer shuts off on its own before the load is done.
What to expect during a visit
A technician locates both ends of the run, pulls the dryer out enough to reach the transition hose, and works brushes through the duct while a vacuum captures the loosened lint. Long runs, multiple elbows, rooftop terminations, and ducts hidden in a crawlspace or second-story wall take more time and equipment. After cleaning, the exhaust connection is reseated and airflow is checked at the outside vent. Cost depends on the length and layout of the run, how the vent terminates, and how much buildup is present, so it is best handled with a quick look and a quote rather than a flat number over the phone.
Why use a professional
Long or rooftop-terminating ducts are hard to reach fully from inside, and the goal is to clear the entire run, not just the first few feet. Blocked vents also matter for combustion safety: a gas dryer that cannot exhaust properly can push carbon monoxide back toward living space, so a clear, correctly connected duct protects more than dry times. A technician has the brushes, vacuum, and access to clean the full path and verify airflow at the end. We do not ask homeowners to climb onto roofs to reach an exterior vent.
Serving greater Seattle and the Puget Sound
Damp Pacific Northwest conditions mean dryers here work hard year-round, and a restricted vent shows up fast as longer dry times and higher energy use. Making dryer vent cleaning part of routine home maintenance keeps the system efficient and lowers fire risk. If you also keep a fireplace or wood stove, ask about our other services while we are out.
Frequently Asked Questions
How often should a dryer vent be cleaned?
For most households, cleaning the dryer vent about once a year is a sensible baseline. Homes that do heavy laundry, dry pet bedding often, or have a long or twisting duct run may benefit from cleaning more frequently. If dry times are climbing or the dryer feels hot, have it checked sooner regardless of the calendar.
Is dryer vent cleaning the same as a chimney sweep?
No. They are entirely separate systems. A chimney carries smoke and combustion gases from a fireplace or stove, while a dryer vent carries hot, moist air and lint from your clothes dryer. Cleaning one does nothing for the other, and the two are never done as a single job.
Can I just clean the lint screen and skip a professional cleaning?
Cleaning the lint screen every load is important, but the screen only catches part of the lint. Fine particles pass through and build up inside the duct where you cannot see or reach them. That interior buildup is what a professional cleaning removes and what a screen alone will never address.
Why does my dryer take so long to dry a load?
Long dry times are the most common sign of a restricted vent. When lint narrows the duct, hot moist air cannot escape, so moisture lingers and the dryer runs cycle after cycle. Clearing the vent usually restores normal drying and lowers the energy the dryer uses.
