Drain Cleaning Houston: $147 to $352 + Grease Clogs (2026)

Drain rows are national figures; no publisher lists Houston-only drain cleaning prices. The service call row is a Houston figure.

Do this now: a backed-up drain in Houston

1. Stop running water and flushing. HomeGuide says several drains backing up at once is a common sign of a main line stoppage.
2. Skip liquid drain cleaner. Angi says the chemicals can erode pipes, and HomeGuide says they can eat through or damage the pipe.
3. Sewage coming up a floor drain or tub? Report it to 311, which lists a residential sewer stoppage with a 1-day service level.
4. Keep children and pets away from any sewage, and photograph the damage before cleanup.
5. Note which fixtures are slow. The plumber will ask, and it tells them whether to snake one drain or the main.

Is it urgent? Which Houston drain clogs need help today

A sewage backup or every drain in the house slowing at once is urgent; one slow bathroom sink is not. HomeGuide's emergency list includes sewage backups and a fully clogged toilet in a one-bathroom home, and it says after-hours drain work often costs 2 to 3 times standard pricing. If sewage reaches floors, see sewage cleanup before anyone cleans up by hand.

Grease and wipes: why Houston drains clog

Grease causes 70% of the sanitary sewer overflows in Houston, Houston Public Works says. The department also says overflows from city-owned lateral lines are increasing, often caused by grease and wipes from homes and businesses, and it runs the Protect Our Pipes campaign to keep both out of drains.

The pipes themselves are under repair. Houston Public Works is upgrading the wastewater system under an EPA Consent Decree, a 15-year commitment now in Year 5, and says the estimated cost has grown from $6 billion to $9 billion. Inside your house, the cheapest drain cleaning is the one you avoid: pour cooled grease in the trash, not the sink.

Snaking or hydro jetting: which a Houston drain needs

Snaking a simple clog costs $100 to $275 and snaking a main line $175 to $600, while hydro jetting a main drain runs $600 to $1,400, HomeGuide says. Jetting blasts out grease and roots that a snake only punches through, but HomeGuide warns that pipes over 40 years old or deteriorated may not be good candidates, and older clay or Orangeburg pipe is more vulnerable.

That matters in Houston, where the 1970s were the biggest building decade: 192,199 of the city's 1,040,576 housing units (18%) were built from 1970 to 1979, City of Houston Planning's 2024 tables show, and the citywide median year built is 1982 by the Census Bureau's count. Ask for a camera look before jetting an older line.

National prices by method and fixture.

When a clog is really a sewer line problem

A clog that returns within weeks, gurgling toilets or sewage at the lowest drain usually points to the main line. HomeGuide puts a sewer camera inspection at $125 to $500, with a $280 average, and recommends one for homes older than 20 years. If the camera finds a break or roots, see sewer line repair in Houston. HomeGuide suggests professional drain cleaning every 1 to 2 years.
