An emergency drain job is one where sewage or wastewater is coming back into your home, or a blockage is stopping every fixture at once. Stop using water, then call. Most urgent visits in Los Angeles cost about $250 to $900 for the clearing, and an after-hours charge of roughly $100 to $200 is common on top. Your written quote states the total before work starts.
You can request a visit from the LA Drain Works home page or the form below, and we'll arrange a local plumber. For a general overview, see drain cleaning company. If the cause turns out to be a failed pipe, emergency sewer line repair picks up from there.
What counts as an emergency drain problem?
A drain emergency is sewage or dirty water coming up through a tub, shower or floor drain, a toilet that will not flush and overflows, or every fixture in the house draining slowly at once. A single slow sink is not an emergency. A backup inside the home is, because sewage carries bacteria and spreads.
Treat these as urgent:
- Sewage in the lowest tub, shower or floor drain.
- A toilet that overflows on its own or bubbles loudly when water runs elsewhere.
- Water backing up in a washing machine standpipe.
- A strong sewer smell with standing water in a drain.
- A blocked line in a rental or a business that makes the space unusable.
These can usually wait until normal hours: one slow sink, a shower that drains slowly but does drain, or a kitchen strainer that fills up.
The warning signs of a coming emergency are easier to act on early: poor drainage in more than one fixture, gurgling, and a smell near the cleanout. Booking a visit at that stage means a planned price rather than an emergency one.
What should I do before the plumber arrives?
Stop all water use, including toilets, the washing machine and the dishwasher. Keep people and pets away from the affected area and wear gloves and boots if you must go in. Photograph the damage. Do not pour chemicals into the drain. Clear what you can by mopping standing water, and open windows.
Why stop the water? Everything you run still goes into the blocked line and comes out at the lowest fixture. Why avoid chemicals? Caustic liquid sits above a clog and can splash on the person clearing it. If you already used a product, say so on the phone.
If a street manhole is overflowing or neighbors have the same problem, the public main may be involved. City of Los Angeles residents can use 311. In unincorporated areas, LA County Public Works takes sewer calls on 800-675-4357 around the clock. If only your home is affected, the blockage is almost always in your own lateral.
What does an emergency drain cleaning visit involve?
A local plumber comes to your property, finds access (usually the cleanout), clears the line with a cable or a jet and tests flow. They look for the cause with a camera where it makes sense. Emergency work focuses on getting water moving, and any repair is quoted separately in writing.
Expect the following:
- A short call about which fixtures are affected, to separate a branch clog from a main line problem.
- Access through the cleanout, or through a pulled toilet if there is none.
- Clearing with a cable or hydro jetting.
- A flow test and, if useful, a camera pass to find roots, cracks or low spots.
- A written quote for any repair work the camera reveals.
Cleanup of a flooded floor is usually separate from drain clearing. Ask your plumber what they handle.
What affects the price of emergency drain cleaning?
The price depends on where the clog is, how hard it is and when you call. A fixture clog costs least, a main line clog more, and heavy roots most. Evening, weekend and holiday visits often carry an after-hours charge. A camera look adds to the price if it is billed separately. Published local ranges are a guide.
| Factor | Effect |
|---|---|
| Fixture or main line | Main line costs more |
| Cleanout available | Without one, extra labor |
| Roots or heavy grease | Heavier tools, longer visit |
| After hours or holiday | Often adds about $100 to $200 |
| Camera inspection | Often about $150 to $350 if separate |
Ask what is included and whether the after-hours charge is a flat fee. That one question prevents most billing surprises.
How do I choose an emergency drain cleaning service?
Choose on clarity, not speed alone. You want a written price before work starts, a plumber who holds a California contractor license for any permitted repair, an explanation of the cause and the footage if a camera was used. Verify the license number on the state board's website. Be cautious about quotes that rise once work begins.
Questions to ask on the phone: what does the price include, is there an after-hours charge, will you use a camera, and what happens if the clog is a collapsed pipe. In older Los Angeles neighborhoods, ask about clay, cast iron and Orangeburg laterals, because the answer changes the repair route.
If water is coming up now, the price request page starts the visit. Say plainly that sewage is entering the house.
Questions people ask
Do you offer emergency drain cleaning service?
Yes, we arrange urgent visits for backups and overflowing drains. We do not promise a response time, and whether an after-hours charge applies is confirmed when we arrange the visit. Your plumber gives you a written price before they start work.
How fast can a plumber get to me?
It depends on the time, the day and what else is booked, so no honest source can promise a number. Say on the call that sewage is entering the house, and ask for an estimated arrival window when you book.
Does insurance cover a sewer backup emergency?
Standard homeowners policies typically exclude sewer and drain backup unless you added a water backup endorsement. Photograph the damage and call the insurer before cleanup. Keep the plumber's invoice and any camera footage, because they show where the blockage was.
Is a backup my responsibility or the city's?
If only your home backs up, the blockage is normally in the lateral you own. If the public main is blocked, several homes are usually affected. LA Sanitation says you own the lateral all the way to the main in the street. A plumber can confirm where the blockage sits.
Can I wait until morning?
If sewage is entering the house, no. If it is one slow drain and nothing is backing up, usually yes. Stop using water and place towels at the lowest drain in the meantime. Watch for any change overnight: if the level in a tub or floor drain rises, that means the line is closing and the job has become urgent. Book the next available visit.
