Pricing guide
Sewer line repair cost in San Diego
Typical 2026 ranges for San Diego County: inspection, clearing, spot repair, full replacement by method, and under-slab work, plus the six things that move a quote. These are typical market ranges, not a quote. Every real number starts with a camera.
Diagnosis and clearing
| Service | Typical San Diego price |
|---|---|
| Camera inspection, recorded, with locate | $250 – $500 |
| Cable clearing of a main line clog | $200 – $450 |
| Hydro jetting, roots or cast iron descaling | $350 – $800 |
| Camera added on the same visit as jetting | low end of $250 – $500 |
| Add a two-way cleanout at the property line | $400 – $1,200 |
A house that backs up every spring and gets cabled for $250 each time is spending the price of a camera inspection every year to avoid finding out why.
Spot repairs
| Repair | Typical San Diego price |
|---|---|
| Spot repair, 3–10 ft, under lawn or dirt | $1,500 – $3,000 |
| Spot repair under a driveway or patio, concrete restored | $2,500 – $4,000 |
| Repair at the connection to the main, in the street | $3,500 – $8,000 |
| Short CIPP sectional liner, one joint | $1,200 – $2,500 |
- Spot repair under lawn or dirt$1,500–$3,000
- Spot repair under concrete$2,500–$4,000
- Repair at the main, in the street$3,500–$8,000
- Sectional liner, one joint$1,200–$2,500
Typical ranges, not a quote.
A spot repair is the right call when the camera shows one problem in a sound pipe. Two spot repairs on the same run in three years is a replacement paid for in installments.
Full replacement, by method
| Method | Per foot | Typical 50-ft lateral |
|---|---|---|
| Open-trench, under lawn or dirt | $80 – $180 | $4,000 – $9,000 |
| Open-trench with driveway and sidewalk restoration | $120 – $250 | $7,000 – $15,000 |
| CIPP lining | $90 – $200 | $6,000 – $12,000 |
| Pipe bursting | $100 – $250 | $7,000 – $14,000 |
| Either trenchless method, long or deep run under the street | $12,000 – $20,000 |
- Open-trench, lawn or dirt$4,000–$9,000
- Open-trench, driveway and sidewalk$7,000–$15,000
- CIPP lining$6,000–$12,000
- Pipe bursting$7,000–$14,000
- Long or deep trenchless run$12,000–$20,000
Typical ranges, not a quote.
A complete quote should include permits, DigAlert (811) marking, the inspection, a new cleanout and a post-job camera; ask. Restoration of lawn and dirt is usually included; concrete, pavers and landscaping should be separate lines so you can see them. Sewer line replacement explains when open-trench makes sense; trenchless explains when it doesn't.
Under-slab work
Lining under the slab $150–$300 per foot, tunneling $250–$450 per foot, a slab cut and short replacement $3,000–$8,000, a full under-slab re-pipe of a post-war ranch $12,000–$30,000. Details on the under-slab page.
What moves the price
- Length. A Clairemont lateral is 40–70 feet. A Mt. Helix or Poway lot can be 100 or more. Everything is per foot.
- Depth. Usually three to six feet in the yard, and six to ten feet at the main on some streets, which means shoring and a bigger pit.
- What's on top. Lawn is cheap to restore. A driveway, a patio, a city sidewalk and a paved street are the expensive part of an open-trench job, and the reason trenchless usually wins here.
- The street. In the City of San Diego the owner is generally responsible for the lateral to the main — confirm for your address with the Public Utilities Department (or your city or district). Work in the sidewalk or street normally needs a right-of-way permit and traffic control, and that last 15 feet is often the most expensive 15 feet.
- Pipe condition. A line that can be lined costs less than one that has to be burst, which costs less than one with a collapse or belly that needs a dig.
- Access and soil. A narrow side yard, a slope, rock in East County decomposed granite, or a high water table near the bay all slow the job.
A worked example
A 1958 slab ranch in Clairemont Mesa: 55-foot clay lateral, 4 feet deep at the house and 7 at the main, roots at three joints, a small offset under the driveway, and the last 12 feet under the street. Pipe bursting from a pit at the house to a pit at the curb, then a short pull to the main: 55 feet at $160 is $8,800; the connection at the main with the right-of-way permit and traffic control, $2,200; new two-way cleanout, $600. About $11,600, usually a day, no concrete touched, camera before and after. The same lateral quoted open-trench would be around $7,000 for the dig plus $3,000–$4,500 to replace the driveway section and a sidewalk panel, and three days. These figures are illustrative.
How to read a sewer repair quote
Ask for the footage of pipe, the method, the depth, who pulls the permit, whether the connection at the main is included, what restoration is included, and whether there's a post-job camera. A quote that's a single number with the word "replacement" on it can't be compared with anything. And a contractor who wants a decision today, or a deposit before a camera has been run, is selling something other than sewer repair. How to read a sewer repair quote goes line by line. Worked examples by method are in sewer line repair cost in San Diego, and the trenchless-only version is trenchless sewer repair cost.
Ways to keep the bill down
- Camera early. A $250–$500 inspection at the first slow drain often finds a spot repair, not a replacement.
- Add a cleanout once. It cuts the time on every future visit.
- Do the lateral and the slab together. One mobilization costs less than two, a year or two apart.
- Ask for both methods. Where trenchless and open-trench would both work, see both prices with restoration included.
- Do your own prep. Clear the side yard, move plants out of the pit spots, and move cars. It saves crew time.
- Book outside the rush. Spring and early summer are easier to schedule than the first week of the rainy season.
Paying for a large job
Most people don't have $12,000 set aside for a pipe. A few options are worth asking about. Some jobs can be phased, with the yard section now and the street or slab section later, as long as each phase is cameraed. Some contractors offer payment plans; read the terms and the interest rate carefully. Your homeowners policy may cover part of the damage inside the house even when it doesn't cover the pipe, so ask your agent. And never pay a large deposit up front; California limits down payments on home-improvement contracts, so check the current rule on the CSLB site.

Is it cheaper to repair or replace a sewer line?
Repair, if the camera shows one break in a pipe that's otherwise sound. Replace, by lining or bursting, if there are problems at several points, the cast iron has channel rot along its length, or you've paid for clearing more than twice in a few years. On a 50-foot lateral the gap between a second spot repair and a liner is often only a few thousand dollars, and the liner ends the problem.
Does homeowners insurance cover sewer line replacement in California?
Often not the pipe itself; many policies treat a worn-out lateral as maintenance, though some cover sudden damage and cleanup inside the house. Read your policy and ask your agent. A service line endorsement is usually a modest add-on — ask your agent for the price, the limit and the deductible. Utility line protection plans are a monthly fee with a per-claim cap — read the cap and the exclusions. See does homeowners insurance cover sewer line repair.
What does a sewer line repair cost for a typical 1950s San Diego house?
For a 40–70 foot clay or cast iron lateral: camera $250–$500, spot repair $1,500–$4,000 if there's one bad section, trenchless replacement $7,000–$14,000 if there are several, more if a long run is under the street. Under-slab cast iron is priced separately at $150–$450 per foot depending on method. Typical ranges, not a quote.
Why do two quotes for the same house differ so much?
Usually because they price different jobs. One may stop at the property line while the other reaches the main. One may include concrete restoration, a new cleanout and a post-job camera; the other may list them as extras later. Ask both to price from the same footage and the same scope, then compare.
