Drain Cleaning San Antonio: $147 to $352 + SAWS Rules (2026)

All rows are national figures; no publisher lists San Antonio-only drain cleaning prices.

Do this now: a backed-up drain in San Antonio

1. Stop running water and flushing. Several drains backing up at once is a common sign of a main line stoppage, HomeGuide says.
2. Sewage coming up a drain? Call SAWS at 210-704-7297 to report it so SAWS can inspect its sewer main, then call a plumber for your side.
3. Skip chemical drain cleaners; Angi and HomeGuide both say they can damage pipes.
4. Find your outdoor cleanout if you have one. The plumber will use it.
5. Keep children and pets away from any sewage and photograph the damage.

Is it urgent? Which clogs need help today

Sewage backing up or every fixture draining slowly is urgent; one slow sink can wait. 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. Sewage on floors?

Your side or SAWS's side: who clears the clog

SAWS says your licensed plumber should clear any blockage on your side of the main, and that if there is a blockage or a collapsed pipe on the SAWS side, SAWS will clear and repair the line. Report the backup to SAWS at 210-704-7297 so it can send a team to inspect the sewer main. If the blockage turns out to be on your side, SAWS does not reimburse the plumber.

If your plumber finds the blockage beyond your property line, in the right-of-way, street, alley or easement, SAWS's Sewer Lateral Reimbursement Program can pay back the plumber's normal and customary charges for locating it. The steps are on sewer line repair in San Antonio. SAWS's Plumbers to People program, which fixes fresh water leaks for qualifying owners, does not cover clogged pipes or drain leaks.

Snaking or hydro jetting a San Antonio drain

Snaking a simple clog costs $100 to $275 and snaking a main line $175 to $600, while hydro jetting a severe main clog runs $600 to $1,400, HomeGuide says. HomeGuide warns that pipes over 40 years old or deteriorated may not suit jetting, and that clay or Orangeburg pipe is more vulnerable. San Antonio's median home was built in 1985, the Census Bureau's 2020 to 2024 survey shows; ask for a camera look before jetting an older line.

Do not forget the AC drain. San Antonio averages 122.4 days a year at or above 90 F (NOAA normals), and HomeGuide prices clearing a clogged AC condensate drain line at $75 to $250.

Hiring a drain cleaner in San Antonio

1. Check the plumber's license on the TSBPE public search.
2. Ask whether the price covers one drain or the main line.
3. If the plumber says the blockage is past your property line, ask them to follow the SAWS reimbursement steps.
4. Get the price in writing before work starts.
