How Much Does Drain Cleaning Cost?
By the HomeLintel Editorial Team · Reviewed 2026-08-24
Professional drain cleaning runs $125–$800, with a typical single-fixture clog — kitchen sink, tub, bathroom sink — cleared for $150–$350. Main sewer line clogs cost more ($250–$800 snaked) because the equipment is bigger and the stakes are higher.
The pricing pattern to understand: you're paying for access and machine size, not mystery. A sink trap is minutes; a main line 70 feet out through a roof vent is not.
Cost by job
| Item | Typical range | Notes |
|---|---|---|
| Bathroom/kitchen sink or tub | $125 – $350 | Snake through trap or nearby cleanout. |
| Toilet auger | $100 – $300 | For what a plunger won't move. |
| Laundry/floor drain | $150 – $400 | Often ties into longer branch runs. |
| Main sewer line (snake) | $250 – $800 | Through cleanout; add cost without an accessible cleanout. |
| Hydro jetting | $350 – $900 | High-pressure wash-out for grease and roots; cleans, not just pokes. |
| Camera inspection add-on | $100 – $300 | Worth it on any repeat main-line clog. |
| Emergency/after-hours premium | +50 – 100% | Weekend sewage backups price accordingly. |
Snaking vs hydro jetting
A snake drills a hole through the clog — fast, cheap, and often all you need. Jetting scours the pipe walls clean with high-pressure water, removing the grease layer or root mass the snake threaded through. The honest rule: first-time clog, snake it; recurring clogs in the same line, jet it once and camera it — you're either ending a grease cycle or discovering a pipe problem that no amount of cleaning fixes.
When it's not a clog
Multiple drains slow at once, backups at the lowest fixture when upstairs drains run, or sewage at a floor drain mean the main line — see our sewer line guide. And a drain that re-clogs every few months isn't bad luck: it's roots, a belly, or a broken section presenting as a maintenance bill. The $200 camera inspection that ends a $300-per-visit cycle is the best money in this category.
What actually works preventively
Skip chemical drain cleaners — they damage pipes, create hazards for whoever snakes after them, and rarely clear real clogs. What works: mesh strainers, grease in the trash (never the kitchen sink), enzyme treatments monthly for organic buildup, running hot water after kitchen use, and — for homes with root-prone laterals — an annual preventive jetting at a scheduled price instead of an emergency one.
Frequently asked questions
How much does it cost to unclog a main sewer line?
Snaking through an accessible cleanout: $250–$800. No cleanout (roof vent or pulled toilet access): add $100–$250. Hydro jetting a rooty or greasy main: $350–$900.
Why does my drain keep clogging?
Repeat single-fixture clogs: grease/hair accumulation or a venting problem. Repeat main-line clogs: roots, a bellied section, or pipe damage — camera it once instead of snaking it forever.
Is hydro jetting safe for old pipes?
On sound pipe, yes — pressures are adjusted to the material. On badly corroded cast iron or fragile Orangeburg, jetting can finish what decay started, which is why reputable companies camera-inspect questionable lines before jetting.
Are chemical drain cleaners bad for pipes?
Caustic cleaners generate heat that damages PVC and eat at metal pipes; they also rarely clear serious clogs and make the standing water hazardous for the plumber who follows. Mechanical clearing wins on every axis but effort.
