What Drain & Sewer Work Costs in San Jose: 2026 Homeowner Guide

• Standard drain clearing: $150–$350. The routine call — a fixture or a branch, cleared through a cleanout or the fixture itself.
• Harder jobs, to about $650, where access is poor or the blockage is deep.
• Main sewer line: $500–$1,000+.
• The lateral to the street: $800–$1,100+.
• Camera inspection as an add-on: $100–$300.

• Typical residential job: $350–$600.
• Roots or heavy grease: $350–$650.
• By line: interior $300–$700, main $500–$1,000+, lateral $800–$1,100+.

Jetting is not a more expensive version of cabling; it is a different tool for grease, scale and fine root hair. On fragile pipe it is the wrong tool, which is a reason to look before choosing.

• Bay Area total: $8,000–$18,000 for most houses.
• Per foot: $50–$250 for the pipe work; $150–$300 all-in once surface restoration is counted.
• Trenchless — pipe bursting or lining: $80–$250 per foot, usually cheaper overall once a driveway, walkway or mature lawn is in the path.
• Most replacements finish in a day, excluding the paperwork around them.

What moves you through that range: depth, length, what is above the line, whether the street has to be opened, and whether the failure is one section or the whole run. A spot repair on a single collapsed length is a different order of money from a full replacement, and a camera is the only honest way to tell which you need.

An approved wye cleanout is a four-inch minimum access point brought to the surface, sited within five feet of the sidewalk on the property side. Its value is not convenience — it is the trigger for the City's maintenance of the lower lateral.

Installing one is permitted work:

• The permit comes from the Building Department, (408) 535-3555. A single-family owner may install it themselves under permit, with the City's diagrams and instructions, or hire a contractor.
• The work must be inspected before backfill. The replaced line and the cleanout stay exposed until it is signed off.
• The Department of Transportation, (408) 794-1900, answers questions about the approved cleanout and the fee to have one installed.

A plumbing permit is also required to repair or replace a building drain or a building sewer — not only for the cleanout.

If you are weighing this against a repeat-backup problem, weigh it properly: the cleanout is a permitted job with a known scope, and on the other side of it sits the section of pipe that is most expensive to reach and, with the cleanout in place, no longer yours to reach.

San José does not impose a point-of-sale sewer lateral inspection the way several cities on the Peninsula do. That is not the same as nobody asking: buyers' inspectors raise laterals routinely on older stock, and a dated camera recording is the cheapest way to answer them. If your buyer's city or lender asks for something more, that requirement is theirs and not the city's.

Depth and length, which are geography. Pipe material — clay joints and Orangeburg fail differently and are worked differently. Access: a cleanout at the house, a cleanout at the line, or neither. What is on the surface: lawn, pavers, a driveway, a mature tree with roots you would rather keep. And time of day — after-hours rates in this trade are real, and a backup at 9pm costs more than the same backup at 9am.

A single failed length — one collapsed section, one offset joint, one length crushed by a root — can often be dug and replaced on its own, which is a fraction of the cost of a full run and a fraction of the disruption. It is the right answer when a camera shows the rest of the pipe in reasonable condition, and the wrong one when the same footage shows separated joints along the whole length: paying to open the ground twice costs more than doing it once.

The question is not which is cheaper in the abstract. It is what the footage shows, and whether you have seen it yourself rather than been told about it.

After-hours, weekend and holiday rates in this trade are real and they are not small. A backup at nine in the evening is the same work as a backup at nine in the morning at a different price, and the honest advice is that if you can stop using water and wait until the morning, waiting is usually the cheaper decision. If sewage is entering living space, it is not, and nobody should be doing that arithmetic with a floor to clean.

What exactly does the number cover — clearing, camera, permit, inspection, and putting back whatever gets opened? Does it assume access through an existing cleanout, and what changes if there is none? If replacement is on the table, can you watch the footage rather than hear it described? And what happens if the line backs up again next month: in this trade the warranty answer sorts the firms faster than the price does.
