Your dryer needs two full cycles to get one load of towels completely dry. The laundry room feels hot. Sometimes there’s a faint burning smell. These are common signs of a clogged vent, and they’re easy to ignore. Dryer vent cleaning is a small job that lowers fire risk and helps clothes dry faster. In this guide, you’ll learn why it matters and how often to do it. You’ll also see what it costs and get five safe steps to do it yourself. The main point is simple: clean the lint filter every load and the vent at least once a year.
Why Your Dryer Vent Needs Cleaning
Lint can accumulate inside the dryer’s vent duct, even if you clean the lint filter after every load. Over time, that lint blocks airflow. The dryer gets hotter, runs longer, and wastes energy. Lint also burns easily. That’s why fire experts say the same thing again and again: keep the vent clear. Here are the two questions people ask most.
How dangerous is a clogged dryer vent?
It’s a real fire risk. A Seattle Fire Department safety memo cites the National Fire Protection Association (NFPA). It says dryer fires account for roughly 13,820 home structure fires each year, with seven deaths, 344 injuries, and over $200 million in damage. The same memo says the leading cause is failure to clean the dryer. It advises cleaning the lint filter before or after each load. It also says to clean the vent pipe once a year, or more often if clothes take longer than normal to dry.
What are the signs your vent is clogged?
Watch for these:
- Clothes take more than one cycle to dry.
- The dryer or laundry room gets very hot.
- Clothes feel damp or hot when the cycle ends.
- You smell something burning.
- Lint collects around the dryer or the hose.
- The flap on the outside vent doesn’t open when the dryer runs.
One sign may be a small issue. Two or more means it’s time to check the vent.
How Much Does Dryer Vent Cleaning Cost?
The price depends on how long the vent is, where it exits, and how much lint is inside. A short run out a side wall is cheap. A long run with many bends, or a vent on the roof, costs more. Prices also change from place to place. The numbers below come from cost guides, so treat them as rough ranges, not promises.
What’s the average price?
Most homeowners pay roughly $100 to $270. Bob Vila, citing Angi and HomeAdvisor, puts the typical range at $102 to $179, with an average of $139. A 2026 guide from Homeyou lists $128 to $270, averaging $188. If the vent is damaged, replacing it costs more. Homeyou lists $338 to $928 for a replacement. Get two or three quotes, and ask whether an inspection is included.
Should you do it yourself or hire a pro?
Do it yourself if your vent is short, straight, and easy to reach. Hire a pro if it’s long, has several bends, or exits through the roof. Also call a pro if you can’t find the problem or you’re not comfortable moving the dryer. My take: DIY saves money for most simple setups, but a pro is worth it for hard-to-reach vents. If you have a gas dryer and you’re not sure how to handle it, hire a pro too.
How to Clean Your Dryer Vent Yourself
A basic cleaning takes about an hour for most people, and you don’t need special skills. You do need to be careful, because you’re moving a heavy appliance and working with lint and power. Take your time, wear gloves and safety glasses, and follow your dryer’s manual. If anything seems unsafe, stop and call a pro.
What tools do you need?
You don’t need much:
- A dryer vent brush kit with flexible rods
- A vacuum with a hose attachment
- A screwdriver
- Work gloves and safety glasses
- A bag for lint
Brush kits are usually inexpensive and sold at most hardware stores.
How do you clean a dryer vent step by step?
Follow these five steps:
- Unplug the dryer. For a gas dryer, don’t touch the gas line unless you know how. If you smell gas, leave the house and call your gas company.
- Pull the dryer out gently. Disconnect the duct from the back of the dryer and from the wall.
- Clean the duct. Vacuum the dryer’s exhaust port and the duct. Then push the brush through from one end, and again from the other.
- Clean the outside vent. Remove lint from the cover and make sure the flap moves freely.
- Reconnect and test. Put everything back, run an empty cycle, and check that air blows out strongly at the outside vent.
Use a metal duct with proper clamps, and avoid crushing the hose behind the dryer. A kinked or crushed duct blocks airflow just like lint does.
Conclusion
Dryer vent cleaning is quick, cheap, and one of the best ways to cut dryer fire risk. Remember three things. Clean the lint filter every load, and clean the vent at least once a year, or sooner if drying takes longer. Expect to pay about $100 to $270 for a pro, depending on your vent. And do it yourself only if the vent is short and easy to reach. Check your dryer this week. If you’ve noticed longer drying times, don’t wait. If you’ve cleaned your vent, share what you found in the comments.
