A clogged drain is one of the most common plumbing calls a homeowner makes. The good news: most are straightforward fixes. The cost depends on where the clog is, how stubborn it is, and the method a plumber uses to clear it.
Here is a clear breakdown of what drain cleaning typically costs — based on data from HomeAdvisor, Angi, and HomeGuide.
Average Drain Cleaning Cost
Most homeowners pay between $147 and $346 for drain cleaning, with a national average of roughly $242, according to HomeAdvisor. That said, prices vary considerably based on the location of the clog and how deep in the system it sits.
Cost by Type of Drain
| Drain Type | Typical Cost Range |
|---|---|
| Kitchen sink | $100 – $275 |
| Bathroom sink | $100 – $250 |
| Shower or tub | $150 – $275 |
| Toilet | $110 – $275 |
| Main sewer line (standard) | $200 – $500 |
| Main sewer line (hydrojetting) | $600 – $1,400 |

Simple fixture clogs — a kitchen sink or bathroom drain — are usually the least expensive jobs. They are quick, require minimal equipment, and most plumbers can resolve them in under an hour.
Main sewer line clogs are more involved. A standard snake can often clear them in the $200–$500 range, but if roots have infiltrated the line or there is significant buildup, hydrojetting — a high-pressure water cleaning method — may be required. That typically runs $600 to $1,400, per HomeGuide.
How Plumbers Charge
Most plumbers charge one of two ways:
- Flat rate per job: Common for standard fixture clogs. A fixed price regardless of time.
- Hourly rate: Typically $75 to $150 per hour depending on your region and the plumber, per Thumbtack. More complex jobs or after-hours calls often run at the higher end.
Service call or trip fee — Many plumbers charge a fee just to come out, typically $50 to $150, which may or may not be rolled into the job cost. Always ask upfront.
What Makes a Drain Clog More Expensive?
Several factors push costs upward:
- Deep clogs. The farther the clog is from the fixture, the harder it is to clear.
- Grease buildup. Kitchen drain clogs caused by years of grease accumulation may require multiple passes or hydrojetting.
- Tree root intrusion. Roots growing into sewer lines are one of the most expensive drain issues and may require pipe repair or replacement after clearing.
- Emergency or after-hours service. Calling a plumber on a weekend or holiday typically adds a premium — often 25–50% above standard rates.
- Camera inspection. If the plumber cannot locate the clog, a sewer camera inspection can add $150–$400 to the job but gives you a clear picture of the problem.
Can You Clear a Drain Yourself?
For simple fixture clogs, yes — a plunger, a $30 drain snake from a hardware store, or an enzyme-based drain cleaner can clear many basic blockages without calling a plumber.
What to avoid: Chemical drain cleaners (like Drano) are sometimes effective on mild clogs, but can damage older pipes — especially PVC and older metal pipes — if used repeatedly. Most plumbers recommend against regular use.
When DIY is not enough:
- The clog comes back within days of clearing it
- Multiple drains in the home are slow or backing up simultaneously (likely a main line issue)
- You hear gurgling in other fixtures when one drain runs (another sign of main line involvement)
- Sewage odor is present inside the home
When to Call a Licensed Plumber
Call a plumber — rather than trying to DIY — when:
- Multiple fixtures are draining slowly at the same time. This almost always means the main sewer line is involved, not just an individual fixture.
- You have sewage backing up into a bathtub or floor drain. This is an urgent situation that needs immediate professional attention.
- Your home is older and has cast iron or clay sewer pipes. These lines are more fragile and require a careful approach from someone experienced with them.
- You have tried a drain snake without success. Going deeper without the right equipment can sometimes push a clog further or damage the pipe.
