How should plumbers price drain cleaning?

Drain calls are the bread and butter of most service plumbing, and they're also where owners give away the most money. A clog you clear in 20 minutes because you've done a thousand of them is worth the same to the homeowner as one that takes an hour. If you're billing by the clock, you're charging yourself for getting good at the job.

Price the line, not the clock

The simplest drain price sheet is organized by two things: which line it is, and how you get into it. A kitchen line and a main line are different jobs with different cables, different risks and different odds of coming back. Access matters just as much. Running a cable from a clean, reachable cleanout is one job. Pulling a toilet, working from a crawlspace or climbing onto a roof to go down the vent is another.

Flat pricing per line also makes the phone easier. Instead of guessing at hours, you can tell a caller the price for their kind of clog once you see where the access is. If you haven't committed to flat rates yet, the case against hourly plumbing pricing walks through why.

Typical drain cleaning prices by job

These are ranges owners commonly report, not a price list. Your local market, your drive times and your overhead decide where you land inside them.

Ranges are general and vary by market and year. Check what shops near you charge before setting yours.

What should raise the price

A good price sheet names the things that change a job, so the tech isn't negotiating from scratch in someone's kitchen. The usual ones:

• No usable cleanout. Going through a toilet flange means a new wax ring and a reset. Going through a roof vent means a ladder, a harness and weather.
• Roots and old pipe. Clay and cast iron lines fight back. Roots return every growing season, so the first clear is rarely the last.
• Bigger machine, bigger price. If the job needs the large sectional machine or the drum machine instead of a hand spinner, it should cost more.
• Repeat clogs. A kitchen line that plugs three times in a year is telling you something about the pipe, not the grease.
• Hour of the day. Night and weekend drain work belongs on its own rate, covered in setting emergency plumbing rates.

The guarantee question

Customers ask "what if it clogs again next week?" more on drains than on any other plumbing work. How you answer shapes your price.

Many shops offer something like a 30-day warranty on a main line clear, void if the camera shows roots, a belly or a broken section. Write the conditions on the invoice. If you give away a free return trip on a line full of roots, you've quietly doubled your labor on that job.

Selling the camera without being pushy

The camera is the second line item most drain calls should at least mention. The honest pitch is simple: "It's draining now, but I don't know why it clogged. For $225 I can run a camera and show you." Some homeowners say no, and that's fine. The ones who say yes often find roots at a joint or a sag in the line, and that turns a one-time clear into a spot repair or a sewer replacement quote.

Two habits help. Offer the camera before you pull the cable out, while the homeowner is still thinking about the backup. And give them the recording or a few screenshots, because a picture of roots does more selling than anything you say.

Where drain pricing usually leaks

Look at your last month of drain invoices and check for three things. First, main lines priced like sink lines because the tech felt bad charging more. Second, toilet pulls and roof trips that never made it onto the ticket. Third, free return visits on lines that were never cameraed. Fix whichever one shows up most, and make sure whoever answers your phone knows the starting prices, using the same wording as your service call fee so nothing sounds different from one call to the next.
