Drain Cleaning Cost

Most clogs are cleared in one visit. Angi puts the average professional drain cleaning at $246, with most homeowners paying $147 to $352. HomeGuide's wider range, $100 to $800, covers everything from a slow sink to a blocked main line.

Cost by drain

Kitchen sinks clog with grease and food scraps, bathroom drains with hair and soap. A clog that affects only one fixture is usually close to that fixture and cheap to clear. When several drains back up at once, the blockage is usually in the main line, and the price moves to the top of the range.

Cost by method

Snaking breaks up or pulls out a clog with a cable. Hydro jetting scours the pipe walls with high-pressure water, which removes grease and roots more completely. It costs more and is usually saved for main lines and repeat clogs.

Other drains: storm, French or drain tile cleaning costs $200 to $600, and an AC condensate drain line costs $75 to $250 (HomeGuide).

How plumbers bill

Some companies charge a flat fee per drain; others bill by the hour. HomeGuide lists plumber rates of $45 to $150 per hour, with a $50 to $200 minimum call-out fee during normal business hours. Angi notes that most quotes assume an hour or two of labor unless something goes wrong. See plumber cost per hour for more on rates.

After-hours and emergency calls

HomeGuide reports that after-hours emergency rates are often 2 to 3 times standard pricing. If water is not overflowing and you have another working toilet or sink, waiting for a regular weekday appointment is usually much cheaper. See emergency plumber cost.

When a clog points to a bigger problem

• The same drain clogs again within weeks.
• Several drains back up at once, especially the lowest ones in the house.
• Gurgling toilets or a sewage smell.

These signs often mean roots, a sag or a break in the sewer line. A camera inspection shows the cause before you pay for repeated cleanings. Compare sewer line repair cost.

Ways to save

• Clear minor clogs yourself with a plunger or hand auger; Angi estimates DIY saves an average of over $100 per clog.
• Ask whether the quote is flat-rate or hourly, and whether a camera inspection is included.
• Keep grease, wipes and food scraps out of drains to prevent repeat visits.

How a plumber clears a drain

Most drain calls start with the simplest tool that will work. For a slow sink or tub, that is usually a hand auger or a small drum machine fed through the drain opening or the trap. If the clog is further down the line, the plumber moves to a larger machine at a cleanout, which gives a straight shot into the main line without pulling a toilet. When roots, grease or scale keep coming back, a camera inspection shows what is actually inside the pipe, and hydro jetting may be suggested to scour the walls rather than just punch a hole through the blockage.

What pushes the price up

• Location of the clog. A fixture drain is quick; a main line that backs up into several fixtures takes bigger equipment and more time.
• Access. A home with an outdoor cleanout is faster to work on than one where the plumber has to pull a toilet or go through the roof vent.
• Time of day. Nights, weekends and holidays usually carry an emergency rate.
• What the camera finds. Broken, sagging or root-filled pipe turns a cleaning into a repair quote.

When cleaning is not enough

If the same drain clogs every few months, the problem is often the pipe itself: a belly where water and waste sit, cracked clay or cast iron, or roots getting in at the joints. In that case a camera inspection before paying for repeated cleanings usually saves money, because it tells you whether you need a spot repair or a larger sewer line job.

Questions to ask before the plumber starts

1. Is the price flat or hourly, and does it include the trip fee?
2. Will you clear the line from a cleanout or through the fixture?
3. Is a camera inspection included, and will I get a copy of the video?
4. If the clog comes back, is there a callback period at no charge?

Tips for Texas homes

Many older Texas homes have cast iron or clay sewer lines, and mature trees are common in established neighborhoods, so root intrusion is a frequent cause of main line clogs. In areas with hard water, mineral scale can also narrow older drain pipes over time.

Mistakes that make clogs worse

Chemical drain openers are the most common one. They can soften an organic clog, but they rarely clear a blockage that sits far down the line, and the caustic liquid then sits in the trap. A plumber who has to open that trap or run a cable through it is working with a hazardous chemical, and some companies charge extra for it. Older metal pipes can also be damaged by repeated use.

The second mistake is pushing the clog further in. Plunging a toilet hard when the main line is blocked can force wastewater out of the lowest drain in the house, often a shower or a floor drain. If more than one fixture is slow, stop plunging and call.

The third is ignoring the cleanout. Many homes have an outdoor cleanout cap near the foundation. Keeping it visible and accessible, not buried under mulch or paved over, lets the plumber reach the main line quickly and can shorten the visit.

Keeping drains clear between visits

• Run hot water for a short time after washing greasy pans, and wipe pans with a paper towel before washing.
• Use a hair catcher in showers and tubs and empty it often.
• Only flush toilet paper. Wipes labeled "flushable" still cause many main line clogs.
• If you have mature trees near the sewer line, ask whether a periodic maintenance cleaning makes sense for your home.
