How to start a drain cleaning business
Drain cleaning is one of the few trades where you can start with a single machine and build to a serious business through equipment upgrades funded by the work itself.
Week 1: check the licensing line
This is genuinely first and it varies more than people expect.
Some states treat drain clearing as a distinct activity you can perform without a plumbing licence. Others treat it as plumbing work requiring a licensed plumber. The distinction usually turns on whether you open or alter pipework — clearing a blockage through an existing access point is often permitted, cutting into a line is not.
Confirm with your state board before trading. Working over that line voids your insurance.
Then register and insure — $800 to $2,500 a year.
Week 2: the equipment ladder
Buy in this order, funding each step from the work:
1. Drain machine — $1,500 to $6,000. A sectional or drum machine with a range of cables and heads. This is everything you need to start earning.
2. Inspection camera — $2,000 to $8,000. Buy this second, and buy it sooner than feels comfortable.
A camera transforms the business. It turns “I think there are roots” into a customer watching roots on a screen. It sells the repair, justifies the price, and produces the higher-value work that clearing alone never generates. It also protects you — you can show that a line was already collapsed when you arrived.
3. Jetter — $8,000 to $30,000. When volume justifies it. Jetting handles grease and scale that cabling cannot, and it opens commercial restaurant work, which is repeat, scheduled and well-paid.
Weeks 3–8: market on availability
Blocked drains are urgent. Nobody browses. They search, they call, and they book whoever can come today.
Google Business Profile. Real photos, accurate hours, and a genuine answer when the phone rings.
Local Services Ads. Pay-per-lead, high intent, effective before you have organic rankings.
Answer the phone. In this trade more than almost any other, availability beats price. A customer with sewage backing up into a shower is not comparison shopping.
Weeks 9–12: build the higher-value work
Clearing a drain is a $150 to $450 job. The business grows through what the camera finds.
Quote the repair on the spot, with the footage. Root intrusion, bellied lines, collapsed sections, failed joints.
Offer preventive maintenance to customers with recurring root problems — an annual or six-monthly clear at a scheduled rate. Predictable revenue in a reactive trade.
Build commercial relationships. Restaurants, care homes and letting agents have recurring grease and blockage problems and value a contractor who turns up. One restaurant chain relationship can be worth more than a month of consumer work.
Take payment on site, always. Emergency drain work has a high rate of customers who are relieved when you leave and slow to pay afterwards.
What to run it on
Fast dispatch and on-site invoicing are the operational needs.
Jobber at $49/mo plus $29 per seat handles same-day job creation and invoicing with a payment link. QuoteIQ at $29.99/mo is the cheapest way to invoice and take a card at the van, with financing for larger repairs. Housecall Pro adds a flat-rate price book and a dispatch board once you run more than one van.
Questions operators actually ask
How do I start a drain cleaning business?
Check your state's licensing rules first — some allow drain cleaning without a plumbing licence and some do not. Then buy a drain machine, add a camera, and market on emergency availability, which is what this trade is bought on.
Do I need a plumbing licence to clean drains?
It varies. Several states permit drain clearing as a separate activity, others treat it as plumbing work requiring a licence. The line is usually whether you open or alter pipework. Confirm before trading, not after.
What equipment do I need?
A sectional or drum drain machine to start ($1,500 to $6,000), then an inspection camera ($2,000 to $8,000) which pays for itself in diagnosis and upsells, then a jetter ($8,000 to $30,000) when volume justifies it.
Why is a camera worth the money?
Because it turns a guess into evidence. Showing a customer the root intrusion or the collapsed section on a screen sells the repair, justifies the price, and produces the higher-value work that clearing alone never will.
How do I get drain cleaning customers?
Google Business Profile and Local Services Ads, plus availability. Blocked drains are urgent and searched — whoever answers and can come today gets the job, largely regardless of price.
