Sewer lateral cleaning in Los Angeles

Sewer lateral cleaning clears the private pipe that connects your building to the city's sewer main, using a cable or a hydro jet, then a camera to check the result. It fixes buildup and roots, and does nothing for a broken pipe. When the camera finds damage, the next step is sewer line repair. Here is how the cleaning side works in Los Angeles.

What is a sewer lateral, and who owns it in Los Angeles?

The sewer lateral is the pipe that carries wastewater from your building to the public sewer main in the street. In the City of Los Angeles, LA Sanitation says the property owner maintains and repairs the whole private lateral, including the part under the street. LA County Public Works says laterals are owned entirely by the owner they serve.

The lateral has two parts in LA Sanitation's description: the upper lateral from the building to the property line, and the lower lateral from the property line to the main. The city owns the main and the connection structure. This matters for cleaning, because a blockage anywhere on your lateral is yours to clear, even if it sits under the street. LA Sanitation says it may clean a lateral case by case to protect the public system, but you should not count on it.

What does sewer lateral cleaning involve?

A plumber reaches the lateral through a cleanout, runs a powered cable or hydro jet from the house toward the street, clears roots, grease or debris, flushes the line and runs a camera to see the pipe. The camera step separates a one-off clog from a pipe in trouble, and it produces the estimates for anything that follows.

What happens, in order:

1. The plumber finds the cleanout, or another way in if the house has none.
2. A cable with a cutting head clears roots and soft clogs.
3. A jet follows for grease, scale and fine roots.
4. The line is flushed to test flow.
5. A camera shows the pipe condition, with distance readings.
6. The plumber explains what the footage shows and quotes any repair.

Our page on sewer camera inspection shows what to look for in the video. If you want the cleaning side only, see cleaning sewer pipe.

When is cleaning a lateral not enough?

Cleaning is not enough when the camera shows a crack, an offset joint, a bellied low spot that holds water, or roots coming back within months. Those are sewer repair problems, and a cable only clears the symptom. Repeated clogs in the same line are a sign to ask for a camera and an estimate for repair.

Signs that point beyond cleaning:

• The line clogs again within weeks or a few months.
• The camera shows a break, collapse or heavy root intrusion at a joint.
• You have sunken or soggy patches in the yard over the line.
• The house is old and the pipe is clay or cast iron.

In those cases, ask for written estimates for repair and for the options: spot repair, lining or replacement. Our guide to pipe lining versus replacement shows how those compare. For a root-driven problem, see how to get rid of roots in a sewer line.

How much does sewer lateral cleaning cost in Los Angeles?

Published Los Angeles prices run about $150 to $600 for cable cleaning of a sewer lateral and $350 to $900 for hydro jetting, with root-filled lines at $600 to $1,100. A camera pass is $100 to $350, and often discounted with cleaning. Cleaning through an outdoor cleanout sits at the low end.

These are guides, not quotes. Ask the price in writing before the visit, and ask what happens if the plumber has to pull a toilet or use a roof vent. If the camera shows damage, the repair estimate is separate. Published figures for a spot repair are about $1,500 to $5,000, and see sewer line repair cost for more.

Does homeowners insurance cover sewer line repair?

Usually not, if the damage is from age, wear or roots. The California Department of Insurance lists wear and tear and seepage among things generally not covered, while sudden and accidental water damage is a covered peril. Whether your policy pays for sewer line repair depends on the cause and the wording, so ask your insurer.

If a sudden, covered event damaged the pipe, the policy might pay under its terms, and a camera video helps to show the cause. If the pipe simply failed from age, expect the owner to pay. Sewer backup damage inside the home is a separate question, covered on our page about whether home insurance covers sewer backup. For replacement, see whether insurance covers sewer line replacement.

What help is there for sewer lateral repair costs in Los Angeles?

One program can soften a repair bill: LA Sanitation's Sewer Lateral Repair Rebate, which for city sewer customers has been listed at up to $2,500 and goes to repairs by a bonded sewer contractor. Money is first come, first served, and amounts change, so read the current page before you rely on it.

From LA Sanitation's description, an application includes the contractor's invoice with their license number, proof you paid in full, and the permit sign-off within 60 days. LA Sanitation also lists a separate rebate for camera inspection of a lateral, so keep the video and invoice from any inspection. We do not process the rebate, and approval is not guaranteed.

How should I hire for sewer repair after a lateral cleaning?

Get at least two written estimates, ask each contractor to base theirs on the same camera video, and compare scope, not just price. Ask which CSLB classification each holds, who pulls the permit, and what surface restoration is included. A repair over $1,000 in labor and materials needs a contractor with the right classification.

What the answer should include: where the dig or the lining will happen, how long water is off, what happens to landscaping, and what the price covers. If one estimate is far below the rest, ask what it leaves out. We'll arrange a visit and a written quote.

To start, request a written price. Our home page lists the rest of what we arrange.

Questions people ask

How often should a sewer lateral be cleaned?

A lateral with no history of trouble needs cleaning only when a symptom appears. One with roots may need it every one to two years. A camera pass shows whether it is worth doing, so ask for the video and decide from that.

Does the city clean my sewer lateral?

Not as a service. In the City of Los Angeles, the owner is responsible for the private lateral. LA Sanitation says it may clean a lateral case by case to protect the public system. If neighbors are affected too, call its 24-hour line at 1-800-773-2489.

How long does sewer lateral cleaning take?

A clean through an outdoor cleanout often takes one to two hours with a camera pass. A long, root-filled lateral or one with no cleanout can take half a day. Ask for a window when you book. Heavy roots or a collapsed section can add more time.

What happens after cleaning if the camera shows damage?

The plumber explains what the footage shows and gives estimates for repair, such as a spot dig, lining or replacement. You can get a second estimate using the same video. Cleaning alone will not fix a crack or a collapse.
