Dryer vent cleaning costs $80 to $185 for a standard wall-exit installation, according to HomeAdvisor and Angi national cost surveys. Roof-mounted vents and long duct runs with multiple bends cost more, typically $150 to $250. The NFPA recommends annual cleaning for regularly used dryers, and the fire-hazard case for staying current on this maintenance task is straightforward: clogged dryer vents cause approximately 13,820 home fires per year, based on NFPA data.
What does dryer vent cleaning cost on average?
HomeAdvisor puts the national average for dryer vent cleaning at $131, with a typical range of $80 to $185. Angi's cost data aligns closely, reporting a range of $90 to $165 for standard installations. Both sources reflect 2024 survey data from homeowners across the US.
The relatively narrow price range reflects that dryer vent cleaning is a straightforward service with predictable labor time for standard installations. Where prices vary meaningfully is at the high end: roof-mounted vents, long duct runs through attic or crawlspace, and severely compacted lint buildup all require more time and specialized equipment.
| Vent configuration | Typical price range | Notes |
|---|---|---|
| Standard wall exit (under 10 ft) | $80 - $135 | Most common residential setup |
| Wall exit, 10 - 25 ft duct run | $100 - $165 | Extended reach with rotary brush |
| Roof-mounted vent | $150 - $250 | Height, access, and longer run |
| Roof vent with attic access needed | $175 - $300 | Additional labor for attic traverse |
| Severely clogged vent (compacted) | $150 - $225 | Extra time and tools |
| Multiple dryers (laundry room) | $75 - $130 each | Per-unit rate with minimal travel add |

Price by vent location: wall, roof, and long-run duct
Vent location is the single biggest factor separating a standard-priced job from a more expensive one.
Wall-exit vents are the most common residential configuration: the duct runs horizontally from the back of the dryer through the wall and exits with a louvered flap on the exterior. If the total duct length is under 10 feet and the run is straight or has only one 90-degree bend, this is the fastest and least expensive job. Most technicians complete it in 45 to 60 minutes.
Long-run ducts - common in basements, laundry closets on upper floors, or townhouses where the dryer is located far from an exterior wall - require a rotary brush extension system that can reach 20 to 30 feet into the ductwork. Longer runs with multiple bends accumulate lint faster because the bends slow airflow and allow lint to settle. These jobs take longer and cost more.
Roof-mounted vents are used when a wall exit is not available due to the home's layout. The technician must access the roof safely and work from both the roof vent and the dryer connection end. Additional costs for height, safety equipment, and access time make these the most expensive configuration.
Signs your dryer vent is clogged and needs cleaning
The most reliable early sign is drying time. If clothes that previously dried in 45 minutes now take 70 or more, reduced airflow through the vent is a likely cause. Lint builds up gradually, so the change in drying time tends to happen over months rather than days.
Other signs worth acting on:
- The dryer exterior or laundry room air is noticeably hot during a drying cycle
- A burning or musty smell during drying (hot lint smell)
- Lint visible on or around the outside vent flap during operation
- The dryer stops mid-cycle due to thermal shutoff (a safety mechanism that activates when the unit overheats)
- The lint trap is unusually light after a full cycle - more lint may be accumulating in the duct
The NFPA notes that failure to clean is the leading factor in dryer fires (32 percent of incidents). Acting on these signs promptly is worthwhile - the cleaning cost is substantially less than the deductible on a fire claim, and the safety benefit is real.

What happens during a dryer vent cleaning visit?
A standard service call follows a predictable sequence. Knowing what to expect avoids surprises.
The technician arrives with a rotary brush system and high-powered vacuum. They pull the dryer away from the wall, disconnect the flexible duct connector from the back of the dryer, and connect their brush and vacuum system to the duct opening. The rotary brush is fed into the duct, spinning as it advances to dislodge lint from the duct walls. Extracted lint is captured in the vacuum rather than deposited in the laundry room.
After clearing the duct, the technician inspects the duct for damage, collapsed sections, or improper connections. They also check the exterior vent flap to confirm it opens freely and is not blocked by a screen (screen-covered exterior vents are a code violation in most jurisdictions because they accumulate lint faster than any duct run).
The dryer is reconnected, tested for proper airflow, and pushed back into position. The whole service takes 45 to 90 minutes depending on duct length and condition.
Is dryer vent cleaning worth it? The fire hazard case
The NFPA reports approximately 13,820 home fires attributed to dryers or washing machines per year, with failure to clean the vent cited as the leading factor. That number has been consistent across multiple years of NFPA tracking data.
The case for professional cleaning is direct: lint is combustible, and the dryer duct runs near the dryer's exhaust heat. An annual cleaning for $100 to $150 is a straightforward maintenance expense relative to the risk and the cost of a fire.
There is also an energy cost argument. A clogged vent forces the dryer to run longer and work harder to achieve the same drying result, which raises utility costs. A properly vented dryer operates at peak efficiency.
DIY cleaning is genuinely worth considering for short, straight vents. If your dryer is on an exterior wall and the vent exits within 6 to 8 feet of the dryer, a $25 brush kit and 20 minutes of work every 6 to 12 months is a reasonable approach. For longer runs or roof-exit configurations, professional equipment is more effective.
How often should dryer vents be cleaned?
The NFPA recommends at minimum one professional cleaning per year for households that use the dryer regularly - meaning several loads per week year-round. That recommendation is seconded by most major appliance manufacturers in their dryer maintenance guides.
Households that should consider twice-yearly cleaning:
- More than 5 to 6 loads of laundry per week
- A long duct run with multiple bends (more than 20 feet or two 90-degree bends)
- Heavy use of the dryer for bulky items like comforters, towels, and pet bedding
- Lint trap that fills quickly and consistently on each cycle
Households that can safely maintain an annual schedule: one to two people, moderate laundry volume, a short duct run with a direct wall exit.
Dryer vent cleaning vs. air duct cleaning: are they the same?
They are distinct services performed by different types of equipment, though some companies offer both.
Dryer vent cleaning addresses the single duct that runs from the back of your dryer to the exterior of your home. It is a one-duct job typically completed in under 90 minutes.
Air duct cleaning addresses the HVAC ductwork throughout your home - the network of supply and return air ducts that distribute heated and cooled air from your furnace and air conditioner. This is a whole-home service that typically takes 3 to 5 hours for an average home and costs substantially more.
If a company is quoting you "duct cleaning" and you are only seeking dryer vent service, confirm what is actually being quoted. The scope and cost of whole-home HVAC duct cleaning is substantially different from dryer vent service.

Do Not Run Your Dryer if You Smell Burning
If you smell a burning odor from the dryer or laundry room during a drying cycle, stop the dryer immediately and do not restart it until the vent has been cleaned and inspected. This smell indicates lint is close enough to the heat exhaust to be at risk of ignition. Schedule a cleaning before the next use.
Dryer vent cleaning is one of the more straightforward home maintenance tasks to justify: predictable cost, real safety benefit, and a service that most households should book once a year. Knowing the price range for your vent configuration, recognizing the warning signs, and keeping to an annual schedule covers the practical requirements.
Frequently asked questions
How much does dryer vent cleaning cost?
Standard dryer vent cleaning costs $80 to $185 for a straightforward wall-exit vent, based on HomeAdvisor and Angi national cost surveys. Roof-mounted vents, long duct runs, and vents with multiple bends cost more - typically $150 to $250. The price reflects vent location, duct length, and how severely clogged the vent is.
How often should dryer vents be professionally cleaned?
The NFPA and most appliance manufacturers recommend professional dryer vent cleaning once per year for households that use the dryer regularly. Households doing more than 5 to 6 loads per week, or that have longer duct runs with multiple bends, may benefit from twice-yearly cleaning. Lint accumulates faster in longer ducts and those with 90-degree bends.
Can I clean my dryer vent myself?
DIY dryer vent cleaning kits cost $20 to $40 and work adequately for short, straight duct runs of 5 to 8 feet. For longer runs, multiple bends, or roof exits, DIY tools typically cannot reach the full duct length or dislodge compacted lint. A professional uses rotary brush systems and high-pressure air that are substantially more effective on long or complex runs.
What are the warning signs of a clogged dryer vent?
The most common signs of a clogged dryer vent are clothes taking longer than usual to dry, the dryer or laundry room feeling unusually hot during a cycle, a burning smell during drying, lint visible around the dryer door or outside vent flap, and the dryer shutting off mid-cycle on thermal override. Any of these warrant prompt attention.
Does dryer vent cleaning require moving the dryer?
Yes - the cleaner needs access to the back of the dryer to disconnect the flexible duct connector and access the vent inlet. Most technicians pull the dryer out from the wall, clean the duct from both ends, reconnect everything, and push the dryer back into position. This is a routine part of the service and is included in the standard price.
Is dryer vent cleaning covered by homeowners insurance?
Standard homeowners insurance does not cover routine dryer vent cleaning as a maintenance expense. If a dryer fire causes damage and the fire is attributed to a clogged vent, insurers may investigate whether the vent was maintained. Some policies include coverage for fire damage regardless of cause; others exclude fires attributable to owner negligence. Review your policy or ask your insurer.
