Nobody should agree to sewer work in this city without watching the camera footage first. Not a still photo. Not a description over the phone. The actual video, with the footage counter running, so you can see how far from the house the problem is and what kind of problem it is.
Ask for a copy. A contractor who will not hand it over is telling you something.
Four things go wrong, and they are not the same job
Roots are the most common and the least alarming. A hair-fine root finds a joint that is already weeping, thickens over years, and eventually fills the pipe. Cut them out and the line runs again, but they come back, because the joint that let them in is still there.
An offset is where two sections of pipe have shifted out of alignment, leaving a lip that catches solids. Long Beach has an unusual amount of this. The ground here has been sinking and shifting for a century over the Wilmington oil field, and the Newport-Inglewood fault runs right through town, so buried clay and cast-iron laterals have been pulled around in ways their installers never planned for.
A belly is a sag. The pipe has dropped in the middle and lost its fall, so waste pools there instead of running downhill, and solids settle out. This one matters more than the others, because a belly is the one defect that lining will not fix. You can put a perfect new liner inside a sagging pipe and you will have a perfect new sagging pipe. If somebody quotes you a trenchless liner for a belly, they are either not looking at the footage or hoping you did not.
Then there is simple deterioration. In the pre-war neighborhoods, Rose Park, California Heights, Bluff Heights, the lateral is cast iron laid in the 1920s or 1930s. The bottom of the pipe corrodes away first, so the camera shows something that looks less like a pipe and more like a trough. There is nothing to repair there. There is only replacement.
Trenchless is not automatically better
The pitch for trenchless is that your yard, your driveway, and your mature street tree survive the job. That is a real benefit and it is worth paying for when it applies.
Cured-in-place lining pulls a resin-saturated liner through the old pipe and cures it in place, forming a new pipe inside the old one. It works well on a structurally sound line with cracks, root intrusion at the joints, or light corrosion. It is a poor choice on a collapsed section, on a severe offset, and, again, on a belly.
Pipe bursting drags a bursting head through the old line, fracturing it outward, and pulls new HDPE in behind it. This one does fix grade, because you are pulling in a genuinely new pipe. It needs pits at each end and it is unforgiving where the lateral runs close to other utilities.
Open trench is the old way, and here is the part the trenchless salesman skips: on a short run under a lawn, with a straightforward failure and a shallow line, digging is frequently the cheaper and better answer. It is the honest option and it gets dismissed too easily. If your lateral runs thirty feet under grass to the street and it is four feet down, do not pay a premium to avoid a trench you barely mind.
Whose pipe is it
The part almost everyone gets wrong. The lateral running from your house out to the sewer main in the street is generally the property owner’s responsibility, and that usually includes the section under the sidewalk and out into the street, not just the piece inside your fence. So a failure in the parkway strip, under city concrete, is very often still your bill.
Confirm the boundary with the city before you sign anything, because it changes the number substantially. Work in the public right of way means an encroachment or excavation permit through Long Beach, traffic control if it reaches the street, and restoration of whatever concrete gets cut. Those line items are not padding. They are also not optional, and a bid that omits them is not a cheaper bid, it is an incomplete one.
What it costs
A spot repair on an accessible section of lateral, one bad joint, one cracked length, typically lands somewhere around $3,000 to $6,000 in this market. Cured-in-place lining of a full lateral commonly runs $6,000 to $15,000. A full replacement under a driveway or out into the street can exceed $20,000 once permits, concrete restoration, and traffic control are counted.
These are wide ranges on purpose. Depth, length, access, what is on top of it, and whether the city has to be involved move the number more than the method does. Anyone giving you a firm price before the camera has been down the line is guessing, and the guess will be revised upward on the day.
Questions
How do I know it is the sewer and not a drain?
Multiple fixtures, all at once. A single slow sink is a local clog and belongs on the drain cleaning page. But when the toilet gurgles as the washing machine drains, or the shower pan backs up when someone flushes, everything downstream is sharing one blocked path, and that path is the lateral.
Can I just keep having it cleared every year?
You can, and plenty of people do. Run the five-year arithmetic honestly before you commit to it, though, including the year the clearing fails on a Sunday and the line backs up into the house. Annual cabling of a structurally failed lateral is not maintenance. It is a payment plan on a problem you already have.
Do I need a permit?
For a repair or replacement of the lateral, yes, through Long Beach Development Services, and an additional permit if the work enters the public right of way. Your contractor pulls it. Check that they did. An unpermitted sewer replacement is a disclosure problem waiting for you at escrow, and the C-36 license and CSLB number are worth thirty seconds of verification before anybody touches your yard.
Is a sewer line covered by insurance?
Standard homeowners policies generally do not cover the failure of a buried pipe from age or roots, though some carriers sell a service line endorsement that does. Ask yours what you actually have, in writing.
Get the line looked at
Tell us the age of the house and what is backing up. Then insist on the camera before anything else, from us or from anybody. Half the sewer replacements sold in Southern California are sold to people who never saw the inside of their own pipe.
