What drives the price
A simple sink clog is quick work. The cost climbs sharply when the blockage is in the main line, because that requires a powered auger, roof or cleanout access, and often a camera inspection to find the cause.
- Location — a sink trap is cheap, a main sewer line is not
- Whether a cleanout access point exists (no cleanout means more labor)
- Camera inspection add-on, typically $150-$400
- Tree root intrusion requiring cutting heads
- After-hours emergency rates
Should you DIY this or call a professional?
Try it yourself first for a single slow fixture. A $15 hand auger clears most bathroom sink and tub clogs, and a plunger handles many toilet blockages. Skip the chemical drain cleaners — they are caustic, frequently do not work on a full blockage, and a plumber then has to work around a pipe full of acid. Call a pro when multiple fixtures back up at once, which points to the main line rather than one trap.
Signs you need this repair
- Water draining noticeably slower than usual
- Gurgling from a nearby drain when another fixture runs
- Multiple fixtures backing up simultaneously
- Sewage smell near floor drains
How to not get overcharged
Ask for a flat rate to clear the specific drain rather than an hourly rate — open-ended hourly on a stubborn clog gets expensive fast. If a camera inspection is recommended, ask whether the footage is provided to you; you want the evidence if a larger repair is proposed off the back of it.
