Dryer Vent Cleaning Cost: Average Prices & Cost Factors

Lint builds up inside the duct that carries hot air from your dryer to the outside. When the duct clogs, clothes take longer to dry, the dryer works harder, and the lint itself becomes a fire hazard. A cleaning service runs brushes or compressed air through the whole duct, clears the exterior vent cap, and checks that air moves freely.

The prices below come from companies that sell dryer vent cleaning and publish their rates. These are service-provider figures, so they show what companies charge rather than an independent market survey. They carry a check date of Oct 11, 2026.

The length and route of the duct drive the price. A short run to a side wall is the quickest job. A vent that climbs to the roof, passes through several floors, or bends around obstacles takes more time and tools. A badly clogged vent costs more because the crew has to break up packed lint or remove a nest before cleaning.

Where the dryer sits in the home changes the price too. Upper-floor vents are harder to reach from outside, and the crew may need a ladder or longer rods.

• Duct length and route. Long runs and many bends take more time.
• Exit point. Roof vents need roof access, which raises the price and the safety requirements.
• Floor level. Second-floor and higher vents usually cost more.
• Clog severity. Compacted lint or animal nests add labor.
• Vent condition. Crushed, disconnected, or damaged duct may need repair or replacement, which is not part of a basic cleaning.
• Duct material. Rigid metal duct is the safer choice. Flexible foil or vinyl duct traps lint more easily, so a crew may recommend replacing it.
• Extras. Some companies add a fee for a camera inspection, a vent cap replacement, or an airflow test.
• Location. Local labor rates and travel distance change the price.

Pricing depends on where you live, and no national average replaces a local quote. Get quotes from two or three companies in your area for the same vent. Describe the floor, the exit point, and the approximate duct length so the numbers are comparable. Some companies advertise a low entry price and add charges on site, so ask what the quote includes.

Each source below sells the service, and each describes its jobs in its own way. One may count only a standard home, while another builds in the cost of hard-to-reach vents.

The figures overlap, which suggests a typical visit falls in the same general band across these sources. Differences in vent type, home layout, and what the visit includes explain the rest.

A brush rod kit lets you clean the duct yourself.

DIY can work for a short, straight vent on the ground floor. It gets harder with long or bending ducts, roof exits, or heavy buildup. You can also miss damage, loose joints, or blockage at the vent cap. If you try it, unplug the dryer, disconnect gas dryers only if you know how to do it safely, and reconnect the duct securely afterward. Hire a pro when the vent is long, high, or hard to reach.

Dryer lint is flammable, and a blocked vent traps heat. Consumer safety agencies, including the U.S. Consumer Product Safety Commission, warn about clothes dryer fires and recommend regular cleaning of the lint filter and the vent. See the CPSC clothes dryer safety guidance for official advice. Common warning signs of a clogged vent include:

• Clothes that stay damp after a normal cycle
• A laundry room that feels hot or smells like something burning
• A dryer exterior that is hot to the touch
• Little or no air coming out of the exterior vent
• Lint collecting around the vent cap or behind the dryer

If you smell burning or see smoke, stop the dryer and unplug it. Do not keep running it. For gas dryers, a gas smell is a reason to leave the area and call your gas utility. How often your home needs cleaning depends on how much laundry you do and how long the duct is, so follow the dryer manufacturer's instructions.

If the crew finds crushed, sagging, or disconnected duct, cleaning alone will not fix the airflow problem. Replacing flexible duct with rigid metal duct, or fixing a loose joint, may cost extra. Ask for that cost separately so you can decide.

• Is the price flat, or does it change with duct length and floor?
• Does the service include the exterior vent cap and a check of airflow afterward?
• Is the crew insured, and do they use a brush system or only compressed air?
• Will they tell me about damaged duct before they charge for repairs?
• Is there a trip fee or minimum?
