How to Start a Dryer Vent Cleaning Business

How do you start a dryer vent cleaning business step by step?

Form the business, buy a rod kit and capture vacuum, bind liability insurance, price by vent access, clean ten free practice vents, then sell realtors, appliance techs, and the streets you already work.

Zero to first paid job runs two to three weeks, and none of it needs a loan, a shop, or a van. The gate is not money, it is the first ten vents. Bill a stranger before you have timed yourself on a run with two 90 degree elbows and you will eat the cost of a crushed transition duct on your own dinner hour.

• Set up the legal side. LLC or sole proprietorship, EIN, business bank account, and a call to your city or county business license desk.
• Buy the minimum kit. A rotary rod-and-brush system, a vacuum with a capture nozzle, an anemometer, a 24 foot extension ladder, and the drill you already own.
• Bind general liability before you touch a customer's dryer. A $1,000,000 / $2,000,000 policy averages $37 to $49 a month for a solo dryer vent operator.
• Clean 5 to 10 free vents. Friends, family, your own house. Time yourself. A standard side-wall vent should be done clean in under 60 minutes.
• Learn the four code points that make you the expert: 35 feet maximum exhaust duct, no screen at the termination, no fastener protruding more than 1/8 inch into the duct, and no domestic booster fan.
• Write the price list before you quote anything. Standard, second-floor, roof, and nest removal are four prices, not one.
• Build a Google Business Profile around lint-pull photos, and put a real phone number and a booking calendar behind it.
• Book the first job. Door hangers on the streets around your own house, plus one call to every property manager, realtor, and appliance repair tech you already know.

How much does it cost to start a dryer vent cleaning business?

Add up the real line items and a solo start lands at $6,300 to $12,000, of which $2,000 to $3,600 is the tools and insurance you cannot open the doors without.

The figure repeated all over the web is $5,000 to $7,000 all in, and it does not survive addition. Its own breakdown lists $1,500 to $3,000 of vacuum and cleaning tools, $500 to $1,000 of certification, about $500 a year of liability insurance, $1,000 to $2,000 of marketing, and $3,000 to $6,000 of working capital. Add those and you get $6,500 to $12,500. Strip out the working capital, which is a cushion and not a purchase, and the cash you actually hand over before job one is roughly $2,000 to $3,600: a $38 Gardus rod kit, a $1,500 vacuum, and a $444 liability policy at the low end.

Do you need a license or certification to clean dryer vents?

There is no national license for dryer vent cleaning, and most states do not require one. Add whole-house duct cleaning and many states then demand a mechanical or HVAC contractor license.

Cleaning a dryer vent is treated as cleaning work in most of the country. Cutting into ductwork, rerouting a run, or cleaning a whole HVAC system is treated as mechanical contracting. In Texas, anyone who cuts into ductwork needs an Air Conditioning Contractor's License from the TDLR, while duct cleaning limited to the air distribution system does not. Industry sources name Florida, California, and North Carolina as states where HVAC contractor licensing can reach duct cleaning, but none of the three is confirmed by a state agency source, so call the board yourself before you quote repair or reroute work.

Certification is optional and it is the fastest credibility you can buy. The trade's flagship credential is CSIA C-DET, Certified Dryer Exhaust Technician: 50 multiple-choice questions, 80% to pass, $330 for the exam and $315 for the online review course. Take it as a 3 day workshop plus exam, a 1 day review plus exam, or an online proctored exam. Renewal is every 3 years, and since April 1, 2026 CSIA charges $100 to renew online, or you renew by retaking the exam.

• CSIA C-DET: the only dryer-specific credential. $330 exam, $315 online review, renew every 3 years.
• NADCA: offers ASCS, CVI, and VMT for duct systems, with no dryer-vent equivalent to C-DET. Regular membership is $1,055 a year plus a $100 one-time application fee.
• General liability: $37 to $49 a month for a $1,000,000 / $2,000,000 policy on a one-person dryer vent operation. Add broader duct cleaning and it runs $500 to $1,500 a year.
• Commercial auto on a cargo van: roughly $1,200 to $3,500 a year liability only, $2,500 to $7,500 or more for full coverage.
• Workers' compensation only once you hire. Cleaning businesses average $1,619 per employee per year.
• A janitorial or surety bond averages $126 a year, 78% of cleaning businesses pay $100 to $150, and over half carry a $10,000 bond.

What should you charge for dryer vent cleaning?

A standard side-wall clean sells for $80 to $185 and a roof vent for $150 to $250. You reach a $150 to $250 average ticket through access pricing and add-ons, not hourly rates.

Price by access and by risk. A basement side-wall vent and a third-story roof jack are not the same job, and the operators who fail at this trade are the ones who quoted $99 over the phone and then found a two-story ladder set with a starling nest packed into the hood.

Take Marcus, a solo operator in a Dallas suburb, on a Tuesday. Two standard side-wall cleans at $145, one roof-terminated vent at $220, and one clean with bird nest removal at $210 comes to $720 for about six hours including drive time. Fuel, replacement brushes, vacuum bags, and one semi-rigid transition duct cost him $45, so he keeps $675 before tax and insurance. His average ticket that day is $180, and it got there on the roof job and the nest, not on charging more for a basement vent.

How do you get your first dryer vent cleaning customers?

Work the streets around jobs you already have. Door hangers, Google Business Profile photos and reviews, realtors, appliance repair techs, and property managers buying by the unit fill a calendar faster than paid ads.

Run the numbers on a flyer drop. Sara prints 2,000 door hangers for $240 and hangs them over four Saturdays in two subdivisions built in the 1990s, where the runs are long and most have never been cleaned. 21 homeowners call over the next six weeks and 12 book at a $145 average ticket, so a $240 spend returns $1,740. The list is worth more than the cash: those 12 homes get a reminder text next August, because the published recommendation is at least once a year.

Photos sell this trade better than words. Lay the pulled lint out on a drop cloth beside the dryer, take one picture, and text it to the customer before you leave the driveway. Those photos are your Google Business Profile, your ad library, and your referral engine.

• Door hangers on homes 20 years and older, and any street with roof-terminated runs. Skip new builds.
• Google Business Profile with 20 real job photos, then ask for the review at the truck before you drive off. Reviews are how homeowners pick in this trade.
• Realtors and home inspectors. A blocked or improperly terminated vent shows up in inspection reports constantly, and they need a name to hand the buyer.
• Appliance repair techs and laundry retailers. They see dryers that will not dry every week, and a blocked vent is often the cause.
• Property managers and apartment complexes. About $35 per unit is lower per job but fills a whole day with zero drive time.
• Free airflow inspection offers. Measure at the hood, show the homeowner the reading, and the clean sells itself.
• Annual reminder texts. Once a year is the published recommendation, every 6 months for large families, long runs, or ducts with several elbows.

What tools and equipment do you need for dryer vent cleaning?

A rotary rod and brush kit, a HEPA vacuum with a capture nozzle, an anemometer, a drill, and a ladder do every residential job. Inspection cameras and duct machines come later.

The sequence matters more than the brand. Read airflow at the exterior hood before you touch anything, so you have a starting number. Pull the dryer, disconnect the transition duct, and inspect it for crushing and code violations. Feed the self-feeding auger brush on flexible rods through the full run while the vacuum captures at the dryer connection, so lint comes out instead of packing toward the hood. Clean the hood by hand, remove any screen, confirm the flapper swings free. Reconnect with semi-rigid aluminum, then read airflow again. Back pressure above 0.6 inches of water column means you are not finished.

What should the first 90 days of a dryer vent cleaning business look like?

Weeks one and two are setup and free practice vents. Weeks three to six chase reviews and paid residential work. Weeks seven to twelve add apartment and commercial accounts for volume.

What mistakes kill new dryer vent cleaning businesses?

The killers are leaf blower cleaning, never tracing the duct to its outside termination, leaving foil transition hose in place, skipping airflow tests, and charging side-wall prices for roof work.

• Using a leaf blower. It pushes lint toward the far end instead of pulling it out, misses the worst buildup, and used hard it can collapse the duct or knock it off the dryer. That turns a $150 job into a repair bill.
• Not tracing the run to its termination. If the duct dumps into an attic, a crawlspace, or a garage, cleaning from the dryer end hides the real defect.
• Leaving accordion foil or vinyl transition duct in place. Lint packs into the folds and cannot be brushed out. Replace it with semi-rigid aluminum.
• Reassembling with sheet metal screws. Any fastener protruding more than 1/8 inch into the duct becomes a permanent lint catcher and a code violation.
• Re-installing a screen at the termination. Screens are explicitly prohibited at the duct termination.
• Skipping the anemometer. Without a before and after reading you have no proof of result, no basis for an upsell, and no defense when the dryer still runs long.
• Crushing the transition duct when you shove the dryer back. It is the most common post-service failure in the trade.
• Installing a generic inline booster fan on a long run. Domestic booster fans are prohibited in dryer exhaust systems. Only a UL 705 rated DEDPV is legal, and its instructions then set the maximum duct length.
• Quoting one flat rate. Roof jobs run $150 to $250 against $80 to $185 for standard, and third-floor apartment units justify $45 against $35.
• Selling one-off cleanings instead of annual service, when the safety recommendation is at least once a year and every 6 months for heavy users.
• Adding whole-house duct cleaning without checking licensing. That single upsell can push you into needing a mechanical contractor license.

Is a dryer vent cleaning business worth it?

Yes if you sell annual service instead of one-off cleans. Plan on $20,000 to $30,000 in profit as a solo owner at 20% to 40% net margin. Hiring is what moves it higher.

Gross margin is why this trade works. Counting labor and a few consumables, operators report over 70% gross margin on every ticket, and net lands at 20% to 40% once vehicle, insurance, and marketing come out.

Here is the ceiling with a crew. Run two technicians at $22 an hour, each completing 5 jobs a day at a $180 average ticket. That is $900 per tech per day, or $1,800 across both. Labor at 8 hours each costs $352, fuel and consumables run about $120, so $1,328 a day is left before overhead. One cited scaled example in this trade reached $12,600 a month in net profit. Franchise units in a dryer-vent system average about $154,000 a year in revenue, which is system data and not a year-one plan.

The honest floor: a single owner-operator doing dryer vents only should plan on $20,000 to $30,000 in profit in a normal year while the route is still being built. The ones who beat that number added duct cleaning, apartment contracts, or repair work.

When is the busy season for dryer vent cleaning?

Fall is the peak. September and October bookings climb as homeowners run dryers on heavier winter loads. If you also sweep chimneys the calendar flips, and vent work becomes your May through August filler.

Both seasonal patterns in this trade are real, and which one you get depends on what else you sell. A standalone dryer vent business peaks in fall and winter, because cold weather means bulky clothes, layers, and bedding, so dryers work harder and lint builds faster. A combined chimney sweep and vent shop runs the opposite calendar: chimney work October through February, dryer vent work May through August.

• September and October are the trigger months. Homeowners start on winter prep and scheduling windows tighten.
• Spring cleaning season is the standard lever for filling the warm-month dip.
• The recurring anchor is the annual recommendation: at least once a year, every 6 months for large families, long runs, or ducts with several elbows.
• Stack a summer offer for apartment complexes. Property managers schedule bulk work between leases, which is exactly when residential demand dips.

How do you compete with the big dryer vent franchises?

Dryer Vent Wizard charges $100 to $250 for the same clean, and a Dryer Vent Squad owner pays 7% royalty plus about 2% marketing. Match the price, keep the fees, answer the phone faster.

Do not undercut them. Match the price and win on what a franchise cannot flex: answering your own phone, same-week scheduling, and showing the homeowner the airflow reading before and after. The real opening is annual plans, since Dryer Vent Wizard sells maintenance programs at $150 to $200 a year on top of the cleaning and you can bundle the same reminder into your regular price.
