Sewer line repair
Sewer repair and sewer pipe repair in San Jose
Not every bad sewer line needs replacing. When the camera shows one problem in an otherwise sound pipe, the fix is that section — clay, cast iron or ABS — and the rest of the line stays. Most San Jose sewer repair of this kind runs $1,500–$4,000.
The most common sewer repairs in San Jose
This page covers sewer pipe repair. San Jose laterals fail in a handful of predictable ways, and each one has a different fix.
Offset joints in clay pipe. The classic Santa Clara Valley failure. Clay laterals from the 1950s and 60s were laid in two- and three-foot sections with mortar joints. Sixty years of soil movement, a couple of real earthquakes and a lot of small ones, and a joint that was tight is now stepped by half an inch or more. Paper catches on the lip, roots find the gap, and the line clogs every eighteen months. If it's one or two joints, a contractor digs a pit over them and replaces that length with SDR-35 PVC and proper couplings.
Root intrusion at a single joint. A redwood or oak root that has come in at one spot and packed the pipe. Cutting the root buys time; replacing the joint it came through ends it. This is the sewer lateral repair San Jose homeowners in Willow Glen and Cambrian ask about most, usually after the second or third snaking in as many years.
Cracked or collapsed sections. Clay crushed by a truck on a soft driveway, cast iron rotted through along the bottom, Orangeburg that has gone oval. With any collapsed sewer line repair, San Jose contractors first need to know what the rest of the line looks like: if the camera can't get past the collapse, the section sometimes has to be opened up to find out.
Broken connections at the house or the main. The joint where the cast iron under the house meets the clay in the yard is a frequent failure — two different materials, two different rates of movement. The tap at the city main is the other one, and because that work is in the street it normally needs a separate permit for the right-of-way and often a traffic plan. Check with the City of San Jose for what your address needs.
Bellies. A low spot where the pipe has settled, holding water and sludge. Lining can't fix a belly; the only repair is to dig it up and relay that length on compacted bedding at the right grade. Bellies are common where a lateral crosses old fill or a trench that wasn't compacted in 1962.
Repair or replace?
The camera decides. One problem in a pipe that is otherwise intact: repair. Three problems spread along the run, or a clay line with roots at every joint, or any Orangeburg at all: replace, because you'll pay for the second and third repair within five years and still have the same old pipe. The footage says which one you're looking at. When it's replacement, the sewer line replacement page covers open-trench versus trenchless, and the cost page has the ranges.
What a repair visit looks like
- The line is cleared enough to get a camera through — cable machine or hydro jetting depending on what's in it.
- The camera runs from the cleanout to the main, with a locator on the head so the contractor can mark the exact spot and depth on the surface.
- The price is written: method, length, depth, permit, and what the yard will look like when the crew is done.
- A pit is dug over the problem, the bad section cut out, new pipe installed, the inspection called, and the pit backfilled and compacted.
- The line is cameraed again — ask for the recording.
Depth is what moves the price. A repair at three feet in a lawn is a morning. The same repair at seven feet under a driveway near the sidewalk is shoring, a concrete saw, and a second day.
What not to buy
A spot repair on Orangeburg. A repair on a clay line with roots at every joint. A third snaking on a line that needs a new joint. And be wary of anyone who turns a clog into an emergency sewer repair. San Jose lines that clear with a cable and look sound on camera need a cleaning and an inspection, not a dig — and probably nothing more for a few years.
Comparing two sewer repair quotes
Getting a second price is normal for a five-figure line and sensible for a $3,000 one. To make the two quotes comparable, send both contractors the same camera recording, or ask each to run their own and compare the footage. Then line them up on the same points:
- Where the problem is. Both should name the same distance from the cleanout and roughly the same depth. If one says 22 feet and the other says 40, someone hasn't located it.
- What length gets replaced. One section of clay is two or three feet. A quote for ten feet may be sensible if the joints on either side are poor, but it should say why.
- What pipe goes in. SDR-35 PVC with proper transition couplings to the old clay or cast iron is the common choice. A quote that doesn't name the pipe hasn't been thought through.
- The permit and the inspection. Who pulls it, and is it in the price.
- Restoration. Lawn, concrete, pavers. Each one is a line, not an assumption.
- The after video. Ask for it on both quotes.
A large gap between two prices usually means the two contractors saw different problems, not that one is greedy. Ask each one to walk you through the footage, and the reason tends to come out quickly.
Common mistakes with a spot repair
The first is fixing the symptom and ignoring the rest of the run. A repair at 18 feet clears the backup, but if the camera also showed roots at 30 and 45 feet, the next call is already scheduled. Ask what the rest of the pipe looks like before you approve a single pit.
The second is repairing in the wrong season for the soil. Pits dug in saturated winter clay are slower to dig and harder to compact. When a repair isn't urgent, late summer and early fall are the easy months.
The third is skipping the cleanout. If the pit is already open near the house, adding a two-way cleanout is often a small extra and makes the next inspection far cheaper.

How do you know if the sewer line is broken or just clogged?
A clog clears with a cable and stays clear. A broken line clears and comes back — in months, not years — or the cable hits something solid and stops. The camera settles it: it shows a root mass, an offset joint, a crack or a collapse, and the locator marks where it is from the surface. Guessing from the driveway is how people pay for the wrong fix.
Can a sewer line be repaired without digging?
Sometimes. A cracked or root-damaged section in a pipe that still holds its shape can be lined from inside through the cleanout. An offset joint, a belly or a collapse needs a pit. The camera tells you which, and the trenchless page explains what lining can and can't handle.
How long does a spot repair take?
Usually one day. Camera and locate in the morning, dig, replace the section, call for the inspection, backfill. Deep repairs under a driveway or near the street can run to two days for shoring and concrete cutting. In most cases the plumbing is usable again the same evening.
Is a broken lateral usually covered by insurance?
Often not for roots, age or earth movement — many homeowners policies exclude those as wear or earth movement, so check your policy and ask your agent. Some carriers offer a service line endorsement that covers the lateral; it is usually a modest add-on, so ask your agent for the price, the limit and the deductible.
What should I ask before approving a spot repair?
Ask where the problem is and how deep, what the camera showed on the rest of the line, what pipe and couplings go in, who pulls the permit, and what gets restored. Then ask for the after recording, so the next contractor can see the repaired section.
