How this San Jose sewer guide works, and what to ask any contractor

What this site is

This is a free guide for homeowners, not a contractor's office. The pages explain how San Jose sewer laterals fail, what each repair method can and can't do, and what the work typically costs. When you call or request an estimate, the request goes to an independent local sewer contractor partner who performs the work and quotes it in writing. There's no obligation to hire anyone.

What a good sewer job looks like

Look before quoting. A good job starts with a recorded camera run from the cleanout to the main, and you should be able to watch it or get the recording. A sewer contractor who quotes a replacement from the driveway is guessing with your money. The footage should be yours whether or not you hire that company.

Match the method to the pipe. Spot repair for one bad joint. Lining for clay and cast iron that still hold their shape. Bursting for Orangeburg and crushed pipe. Open trench for bellies and short shallow runs. Trenchless is the norm in San Jose because of what a trench through a driveway, a sidewalk and a city street costs here, but it isn't the answer to everything, and a good contractor says so when it isn't.

Permits in the contractor's name. Lateral replacement or lining normally needs a plumbing permit and an inspection before backfill, plus a separate permit for any work in the sidewalk or street. Check with the City of San Jose, and make sure the contractor pulls the permit in their own name. That paperwork is what lets you disclose the work cleanly when you sell.

Honesty when you don't need the work. If a cable clears it and the camera looks sound, you should pay for a cleaning and an inspection and nothing more. If the line has a few years in it, an annual jet-and-camera may make more sense than a liner.

Licensing in California

Sewer lateral work in California is licensed construction work. Check a contractor's license with the California Contractors State License Board (CSLB): ask for the license number and look up its status, classification and bond at cslb.ca.gov before you sign. It takes a minute, and it also lists any complaints. For the rules on which jobs need a license, down payments and contract terms, check the CSLB's rules on its consumer pages rather than relying on what a salesperson tells you. We only use sewer contractors licensed by the California Contractors State License Board — ask for their CSLB number. An unlicensed crew doing a $20,000 lateral can leave you with little recourse and a job you can't disclose.

What to expect from any sewer contractor in San Jose

Whichever company you call, you should get:

• A recorded camera inspection before any repair or replacement price, with the recording sent to you
• A written quote naming the method, the length, the depth, the permits, the restoration and the warranty
• The CSLB license number on the quote, and proof of bond and insurance on request
• A price that doesn't change if you don't sign today
• A second camera run when the work is done

A company that fails two of those is a company whose job you'll be paying someone else to redo.

How to use this guide

If something is backing up right now, start with signs of a broken sewer line to work out whether it's a branch clog, a main line problem or the city main. If you already know the line is failing, the order that makes sense is:

1. Camera inspection — what the footage shows and what it costs.
2. Who owns the lateral — which part of the pipe is yours.
3. Spot repair, trenchless or full replacement — the methods, and when each one fits.
4. Cost — the typical ranges and what moves a quote.

If the line isn't broken but keeps clogging, hydro jetting and drain cleaning explains what maintenance can and can't do.

How the prices on this site work

The figures on these pages are typical ranges for San Jose and Santa Clara County, not quotes. They're there so you can tell whether a written price is in the normal zone or far outside it. Your own number depends on the length and depth of your lateral, what's on top of it, the pipe material, and whether any of the work is in the street. Only a camera run and a site visit can turn a range into a price.

Questions worth asking any contractor

• Can I see the full recording, with the distance counter?
• Where exactly is the problem, and how deep?
• Why this method and not the others?
• What does the price include, line by line, and what isn't included?
• Who pulls the permit, and when is the inspection?
• What's the warranty, in writing, and what voids it?
• How long does this price hold?

A contractor who answers those clearly is easy to compare with the next one. A contractor who avoids them has told you something too.

Red flags

A replacement price before anyone has looked inside the pipe. Pressure to sign the same day. A large deposit up front. No permit on the quote. Footage you aren't allowed to keep. Any one of these is reason to slow down and get a second opinion.

Keeping your own sewer file

Whatever you decide, keep a simple folder for the house: every camera recording, every quote, the permit and inspection sign-off, the warranty, and the after video. Note the date, the distance of each problem, and what was done. It costs nothing, and it pays off three ways. A future contractor can compare new footage with old and see whether a joint has moved. A warranty claim is easy when the before and after recordings are on hand. And when you sell, a buyer's inspector can see the history instead of guessing at it.

When to call San Jose 311 instead

If sewage is coming up in several houses on the street at the same time, if there's a sinkhole or overflowing manhole in the road, or if the backup started with a big storm and the neighbors have it too, the problem may be in the city main. Call San Jose 311 first. Your lateral may still need a look afterward, but the city should know about a main problem as early as possible.

What this guide doesn't cover

Interior plumbing beyond the drain lines and septic systems are outside this guide, and so is selling trenchless to people whose short, shallow line across a lawn would be cheaper to dig. When the problem is the city main rather than your lateral, call San Jose 311.
