Quick Answer
Okay, so here's the quick version. If your dryer isn't drying, it's almost always a clogged vent. A DIY cleaning kit will run you about $30 to $70 and an afternoon of your time. If it's a real mess, or you're just not comfortable, hiring a pro like me will cost anywhere from $100 to maybe $250 for a standard job. Don't put this off – it's a massive fire hazard. A little bit of cleaning can save you a whole lot of trouble, trust me on that.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Unplug the dryer from the electrical outlet. For gas dryers, turn off the gas supply line valve.
Step 2
Carefully pull the dryer away from the wall and disconnect the vent hose from the back of the dryer and the wall duct.
Step 3
Visually inspect the flexible hose for massive lint buildup, kinks, or punctures. Clean it out or, if it's cheap vinyl/foil, plan to replace it.
Step 4
Use a flashlight to inspect the vent opening in the wall and the exhaust port on the dryer itself.
Step 5
Go outside and inspect the exterior vent hood. Make sure the flap moves freely and isn't clogged with lint or blocked by a bird's nest.
Step 6
Assess the condition of the entire vent. If it's flexible vinyl, it's a major cause for concern and should be replaced with semi-rigid metal.

When to Call a Professional Dryer Vent
- If a burning smell persists after you've attempted to clean the vent yourself.
- If the vent run is exceptionally long, has multiple turns, or exits through the roof.
- If you suspect an animal nest or significant obstruction that you cannot see or reach easily.
- If your flimsy vinyl or foil vent ductwork is damaged and needs to be replaced with proper rigid or semi-rigid metal.
- If you have a gas-powered dryer and are not 100% comfortable and knowledgeable about safely disconnecting and reconnecting the gas line.
Prevention Tips
- Clean the lint screen after every single load of laundry. No exceptions.
- Inspect and clean the full dryer vent system at least once a year. Disconnect the hose and vacuum it out.
- Use rigid or semi-rigid metal ductwork for your dryer vent. Avoid the cheap flexible plastic or vinyl ducts like the plague.
- Ensure the dryer vent run is as short and straight as possible. Don't crush the hose behind the dryer.
- Periodically check the exterior vent cap to ensure it's not clogged with lint, snow, or blocked by animal nests.
