Dryer Vent · DIY Guide
You can clean a dryer vent yourself with a vent-brush kit and a vacuum: unplug the dryer, disconnect it, brush out the duct from both ends, and clear the exterior vent. But long runs, rooftop vents, or heavy blockages are safer and more effective for a pro. Here’s the step-by-step — and when to call one.

DIY dryer vent cleaning, step by step
- Unplug the dryer (and shut off gas if applicable).
- Pull the dryer out and disconnect the transition hose from the wall duct.
- Use a dryer-vent brush kit on a drill to brush the duct from the inside.
- Go outside and clear the exterior vent flap; brush from that end too.
- Vacuum loosened lint from both ends, reconnect, and run the dryer on air-only to confirm strong airflow.
When to hire a professional
Call a pro if your vent run is long or has many bends, exits through the roof or a second floor, shows no airflow at all (possible bird nest or blockage), or if drying problems persist after a DIY attempt. Professionals use rotary tools and airflow testing to clear the entire run safely.
Don’t skip it — it’s a safety issue
However you do it, keep the vent clear. The NFPA identifies failure to clean as the leading cause of dryer fires. For frequency, see how often to clean your dryer vent.

Frequently asked questions
Can I clean my dryer vent myself?
Yes, with a vent-brush kit and vacuum for a standard, accessible vent. Long, rooftop, or fully blocked vents are safer for a professional.
How do I know it worked?
Run the dryer on an air-only cycle and check for strong airflow at the exterior vent. Clothes should dry in a single cycle again.
