Sewer Line Repair & Replacement
The warning signs of a sewer line problem, who is responsible for which part of the pipe, and what camera inspections, repairs, and replacements typically cost.
Warning Signs of Sewer Problems
These symptoms indicate a problem with your main sewer line.
Multiple Drains Backing Up
Toilets, sinks, and tubs draining slowly or backing up
Sewage Smell
Foul odor coming from drains or yard
Gurgling Toilets
Gurgling sounds when flushing or running water
Wet Spots in Yard
Unexplained soggy patches or standing water
Recurring Clogs
Main drain clogs happening multiple times per year
Sewer Repair Options
The right method depends on what the camera inspection shows.
Camera Inspection
$150-$350A waterproof camera shows where the problem is and what is causing it. Worth doing before any repair decision.
Sewer Line Cleaning
$200-$600Snaking or high-pressure water jetting clears roots, grease, and debris without digging. It does not fix a broken pipe.
Spot Repair (Trench)
$1,500-$4,000Dig down to a damaged 5 to 10 foot section and replace it.
Trenchless Pipe Bursting
$6,000-$12,000A new pipe is pulled through the old line, breaking it apart in place, so most of the yard is not dug up.
Full Sewer Line Replacement
$5,000-$15,000Replace the whole lateral from the house to the city connection, by trench or a trenchless method such as lining. Get a written quote for your line.
What You Should Know About Your Sewer Line
In most Southern California cities you own the sewer lateral, the pipe that runs from your house to the public sewer main, often including the part under the sidewalk or street. The city or sanitation district maintains the main. The exact rules differ by city, so check with yours before you pay for a repair.
Clay pipe: Many older homes have clay sewer laterals. Clay joints let tree roots in, and many of these lines are near the end of their life.
Cast iron (1970s-1990s): Resists roots better than clay but corrodes from the inside over decades.
Camera inspection: Before buying an older home, have a camera inspection done. This typically typically costs $150 to $350 and can reveal a sewer problem that would cost far more to fix, which you can negotiate with the seller.
Before You Approve a Sewer Repair
Ask for the Camera Footage
A camera inspection should come before any expensive repair. Ask to see the footage yourself.
Check the License
Look up the contractor at cslb.ca.gov and ask for proof of insurance.
Ask About Permits
Sewer lateral repair or replacement usually needs a city permit. Ask who pulls it.
