How to start a drain cleaning business: licensing by state, equipment, pricing and emergency work

What does a drain cleaning business do?

A drain cleaning business clears blockages in the drain and sewer lines of homes and businesses: kitchen and bathroom sinks, tubs and showers, toilets, laundry and floor drains, and the main line out to the street or septic tank. The tools are cable machines (snakes), hydro jetters and inspection cameras; the service is “make the water go down again,” plus the inspection and recommendations that follow.

Typical jobs, from smallest to largest:

• Small fixture drains. Hair in a tub, grease in a kitchen sink, a toy in a toilet. A hand or sink machine, 30 to 60 minutes.
• Main sewer lines. Roots, grease and wipes in 3 to 6 inch lines, cleared from a cleanout with a drum or sectional machine, often with a camera inspection afterward.
• Hydro jetting. High-pressure water that scours grease and scale from the pipe wall, common for restaurants and recurring commercial lines.
• Camera inspections and locating. Finding the break, the belly or the root intrusion, and marking it for repair.
• Preventive maintenance. Scheduled jetting for restaurants, apartment buildings and HOAs with known trouble lines.

What a drain cleaning business does not do, unless it holds a plumbing license: replace pipe, repair the break the camera found, or open walls. That line matters legally, and it also tells you who your best referral partners are: the plumbers who do the repairs.

Do you need a plumbing license to clean drains?

In some states, yes, or at least a registration under a licensed plumber; in others, drain cleaning without pipe repair is treated as a handyman service that needs only a business license. There is no national rule, so check your state plumbing board and your city before you buy a machine. This is general information, not legal advice.

Two examples of how different states handle it

• Texas. The Texas State Board of Plumbing Examiners lists Drain Cleaner-Restricted and Drain Cleaner registrations among the registrations that can be added to a Plumber’s Apprentice registration (the Drain Cleaner registration can also be added to a Tradesman Plumber-Limited license). To register as a Drain Cleaner-Restricted, you must already be registered as a plumber’s apprentice in Texas and pass the board’s verification of training. In other words, in Texas, drain cleaning for pay sits inside the plumbing licensing system, under a licensed plumber.
• California. The Contractors State License Board lists C-36 Plumbing Contractor as the license classification for plumbing work. California also has a minor work exemption: under AB 2622, from January 1, 2025, CSLB’s industry bulletin puts it at jobs under $1,000, and only if the work needs no permit and the unlicensed person employs no one on the project. A single fixture clear may fit; permitted sewer work does not. Unlicensed ads for work up to $1,000 must say you are not licensed, so confirm the current rules with CSLB before you advertise.

Questions to settle before your first job

1. Does my state define drain cleaning as plumbing? Ask the plumbing board directly and keep the answer in writing.
2. Is there a dollar threshold under which no license is needed, and does it cover a main line job?
3. Can I operate under a licensed plumber as a registrant or employee while I build toward my own license?
4. Does my city require a separate contractor registration or a permit for sewer work?
5. What may I say in ads? “Drain cleaning” and “plumbing” are different claims in a licensed state.

Many successful drain companies are started by licensed plumbers who prefer the drain work, or by owners who hire a licensed plumber as the qualifying individual. If you cannot get licensed, partnering with a plumber who takes the repairs is both the legal path and the best lead source. The general registration steps (entity, EIN, local license) are in what licenses are needed to start a cleaning business and LLC for a cleaning business.

What equipment does a drain cleaning business need, and what does it cost?

Start with a sink machine for small fixture drains and a drum or sectional machine for main lines, then add a jetter and a camera once the calls justify them. Professional machines cost from several hundred dollars to several thousand; camera systems cost five figures.

Prices below are from Test Equipment Depot, an online dealer, in October 2026, for RIDGID machines, which are the common reference point. Spartan Tool, General Pipe Cleaners, Gorlitz, Duracable and others sell comparable equipment, often for less, and good used machines are common because they last.

Buy in this order

1. Sink machine, drum machine, cutters and augers, plus a hand auger and plunger set. Enough for most residential calls.
2. A camera, as soon as you are doing main lines regularly. It is how you find and sell the repair, and how you prove the line was cleared.
3. A jetter, when you have restaurants or recurring commercial lines. Gas trailer jetters with higher flow cost far more than the electric starter above.
4. A locator for the camera head, so you can mark the break for the plumber.

Add a van or truck with shelving, because drum machines are heavy and cables are messy. The profit calculator shows how many calls a month cover the equipment payments.

How to start a drain cleaning business, step by step

Settle the license question, learn the machines, register and insure the business, buy the first two machines and a van, set a price list with an after-hours rate, and get on the call lists of plumbers and property managers.

1. Confirm licensing with your state plumbing board and city, and decide whether you operate under a licensed plumber.
2. Learn the work. Machine makers and dealers run training; a season with a plumbing or rooter company teaches more. Cable machines can break wrists and cables can snap; learn on someone else’s truck.
3. Register the business and open a bank account; see how to start a cleaning business for the shared steps.
4. Insure it. General liability with sewer and drain work described, commercial auto, and workers’ compensation when you hire. Ask about sewage backup and water damage exclusions, because a cable through an old pipe can flood a basement. The cleaning business insurance guide explains each policy.
5. Buy the first machines and set up the van.
6. Write your service terms: what is included, what you will not do without a license, how camera findings are reported, and that clearing a line is not a guarantee against a collapsed or broken pipe. Adapt the cleaning contract template.
7. Set prices (next section) and decide your hours.
8. Get on call lists: plumbers, property managers, restaurants, landlords.

Safety basics

• Leather or cable-rated gloves, eye protection, and no loose clothing near a spinning cable.
• Sewage carries pathogens. Wash hands and tools, disinfect the van, and keep a hepatitis vaccination conversation with your doctor.
• Ground-fault protection for every electric machine; water and 115 volts share the same floor.
• Never run a cable blind into a line you suspect is broken; camera it first if you can.

How much should you charge for drain cleaning?

Price per drain, with a trip fee for the visit, a separate price for main lines, a camera inspection fee, jetting by the hour or by the line, and an after-hours multiplier. Most homeowners pay in the low hundreds for a simple clog and more for a main line.

What the marketplace data says

Thumbtack reports a national average of $186 to $549 for drain cleaning, with a low end of $85 and a high end of $1,223. Its table by location shows roughly $100 to $225 for a kitchen sink, $150 to $225 for a bathroom sink, shower or tub, $150 to $215 for a laundry drain, $110 to $275 for a toilet and $100 to $800 for a main sewer line. It lists snaking at about $195 and hydro jetting at $350 to $600, and notes that some companies charge hourly while others use flat service call fees.

A price list structure

A worked example (hypothetical numbers)

Say a residential main line with a cleanout takes one technician 1.5 hours on site plus 30 minutes of driving, at $30 an hour, and uses $10 of consumables and $12 of fuel.

• Labor: 2 hours at $30 = $60
• Consumables and fuel: $22
• Direct cost: $82

Drain work carries heavy overhead (machines, cables that wear, a camera loan, insurance, the van, answering the phone at 9 pm), so give overhead 35% and profit 25%: direct cost is 40% of the price, $82 divided by 0.40 is $205, so a daytime main line clear from a cleanout is about $200 to $225 in this example, with a camera inspection on top. After hours at 1.5 times is about $325. Those figures sit inside Thumbtack’s reported range, which is a check, not a target: your costs set your price. Write the quote with the cleaning estimate template and give the price before the machine comes off the truck.

How do you handle emergency and after-hours drain calls?

Decide in advance whether you take them, what they cost and who answers the phone, because the sewage-in-the-basement call at 10 pm is the most profitable job you will get and the one most likely to burn you out.

• Hours and rates. Publish your regular hours and your after-hours surcharge. Say the surcharge on the phone before you roll.
• Answering. A missed emergency call goes to the next listing. Forward the line to your phone, or use an answering service that can quote your trip fee and book the slot.
• Triage on the phone. One slow sink can wait until morning at the regular price. Sewage backing up in every drain is a main line and goes tonight.
• Payment at the door. Emergency clients are strangers. Take a card on file when you book the call and charge it when the drain runs.
• Rotation. Once you have two technicians, trade on-call weeks and pay an on-call stipend. Nobody does 365 nights.

Emergency calls are also your best source of recurring clients: the landlord whose tenant called at midnight will give you every building after that if the invoice is clean and the report is clear.

A one-page plan and where the first clients come from

Your drain cleaning business plan fits on a page: services, prices, the license path, monthly fixed costs, how many calls cover them, and the five partners who will send the first calls. The math matters more than the document.

Break-even (hypothetical numbers)

If fixed costs are $2,400 a month (van, equipment payments, insurance, phone, software, ads) and an average call brings $260 with $90 of direct cost, each call leaves $170, so about 14 calls a month break even and everything after that pays you. The business plan template turns that into a plan a lender will read.

Where the calls come from

• Plumbers. Many do not want drain calls and will hand them over in exchange for the repair referrals your camera generates. Start with five.
• Property managers and landlords. Clogs are their most common maintenance call. Offer a flat rate per unit and a 24-hour response. The commercial contracts guide shows how to reach them.
• Restaurants. Grease lines on a monthly or quarterly jetting schedule, often paired with the hood cleaner; see how to start a hood cleaning business for that trade.
• Google Business Profile. Emergency searches are “drain cleaning near me” at 9 pm. Reviews, real photos and a phone that answers win them. See the cleaning company SEO guide.
• House cleaning and handyman companies. They see slow drains weekly. Trade referrals.

For scripts and a weekly outreach routine, see how to get clients for a cleaning business. Scheduling software keeps the recurring side (quarterly jetting, annual camera checks, apartment maintenance) on the calendar with reminders and a card on file. Broombook is booking, scheduling and reminders for recurring service businesses; it fits that recurring and property-manager work, and any residential cleaning crew you run alongside the drain truck.
