Top Pipeline Inspection and Maintenance Companies in the Bay Area

The top pipeline inspection and maintenance companies for Bay Area sewer and storm lines are the ones that hold an active California contractor license, run their own camera, cleaning or rehab crews, and have done that work for a public agency. The five companies below meet all three tests, and every fact about them links to its source. They are listed alphabetically, not ranked.

Disclosure: Total Underground Construction (Total UC), an underground contractor in San Leandro, publishes this page. That is why Total UC is not on the list. A short, separate note about us sits at the end, after the list.

This page covers the pipes under Bay Area streets, campuses, business parks and commercial sites: gravity sewer mains and laterals, storm drains and the manholes that connect them. It is written for public works staff, property and facility managers, developers who need new lines inspected before a city accepts them, and general contractors who need a sub. If you run oil or gas transmission pipelines, you need an in-line inspection firm, which is a different industry and is not covered here.

What pipeline inspection and maintenance covers

For municipal and commercial pipe, inspection and maintenance usually means four kinds of work. Each company on this list does at least one of them with its own crews, and most do several.

• CCTV inspection: a crawler camera runs the line and records every defect. Many agencies ask for coding to NASSCO’s Pipeline Assessment Certification Program (PACP), which sorts what the camera sees into structural, operation and maintenance, construction and miscellaneous codes so every crew reports the same defect the same way (NASSCO PACP course syllabus).
• Cleaning: high pressure jetting and vacuum trucks clear roots, grease and debris, often right before the camera goes in so the footage is readable. Our explainer on what hydro jetting is covers how jetting works.
• Rehabilitation: cured-in-place pipe (CIPP) lining, pipe bursting, point repairs and manhole rehab fix defects without digging up the whole street.
• Testing: air, water, smoke or dye tests find leaks and illegal connections, or prove a new line passes before acceptance.

Say a property manager in Hayward is asked by the sanitary district to prove a 600 foot private sewer line is sound. What the district will accept is coded footage with a defect list and a repair recommendation, so ask about the coding standard before you ask about the camera.

How we chose these companies

Each company had to pass three tests, checked between 1 and 4 October 2026. We did not score price, reviews or company size.

1. The company holds an active license from the California Contractors State License Board (CSLB). We list every class the company holds, such as A General Engineering, C-42 Sanitation System or C-36 Plumbing (CSLB classification descriptions).
2. The company’s own website lists pipeline CCTV inspection, cleaning or rehabilitation as work it performs itself. We link that page, and we note where part of the work is done by an affiliate.
3. The company has at least one California public agency contract for pipeline inspection, cleaning or rehabilitation, shown in the agency’s own award, resolution log or staff report.

The company also had to be based in the nine Bay Area counties or run a yard or office there. We left out Total UC, because we publish the page, and Next Level Plumbing, a Total UC partner.

Bay Area pipeline inspection and maintenance firms at a glance

All five licenses showed as current and active on the CSLB website on 4 October 2026. SFPUC is the San Francisco Public Utilities Commission.

Companies we checked that did not make the list

These firms may do good pipeline work, but we could not document all three tests from a primary source on the dates we checked.

• ROSEN Group and American Piping Inspection were on an earlier version of this page. We found no CSLB license for either name.
• Express Plumbing (CSLB #778428) and Sanco Pipelines (CSLB #160382) were also on the earlier version. Both hold Class A licenses, but we did not find a public agency pipeline inspection, cleaning or rehab contract for either.
• 360 Pipeline Inspections, Roy’s Sewer Service and Nor-Cal Pipeline Services describe strong CCTV and cleaning scope, but we found bids rather than awards, or no California agency contract.
• Michels Trenchless and SAK Construction have large rehab records but no Bay Area office we could confirm from a primary source.
• D’Arcy & Harty Construction has a strong SFPUC sewer record but no company website describing its scope.

If a company above sends us the missing document, we will check it and update the page.

How to pick the right firm for your pipe

The right firm depends on what you need at the end: a condition report, clean pipe, or a fixed pipe. Decide that first, then match the firm.

• If you need a condition assessment for a capital plan, hire for inspection and coding quality. Ask for PACP certified operators, a sample report and the file format your GIS or asset team uses.
• If you have recurring backups or a district cleaning order, hire for cleaning capacity: jetter and vacuum trucks, night work, and how fast they respond. Roots are the usual repeat offender; our guide to tree roots in sewer lines explains why cutting them out rarely holds.
• If the camera already found defects, hire for rehab. Ask which methods they install with their own crews (CIPP, pipe bursting, point repair) and what warranty and post-repair video they provide. Our comparison of trenchless and traditional sewer repair lays out when each makes sense.
• If a city or district has to accept a new line, ask the agency what it needs to see first, then hire a firm that has passed that agency’s inspections before.

1. Write down the footage, pipe sizes and access (manholes, cleanouts, easements) before you call anyone.
2. Ask each firm for a sample report and a public agency reference.
3. Check every license on the CSLB license lookup.
4. Compare bids on footage inspected and cleaned, not on a lump sum.

Picture a facilities director at an East Bay school district who budgets for “sewer inspection” and gets three quotes that differ by three to one. One prices camera only, one includes heavy root cleaning, one adds coding and a rehab plan. Line them up by footage and deliverable and most of the gap disappears.

If your project is new pipe rather than existing pipe, our list of underground utility construction companies in the Bay Area uses the same three tests for builders.

Pipeline inspection FAQ

What is NASSCO PACP certification?

PACP is the Pipeline Assessment Certification Program run by NASSCO. It trains and certifies operators to code sewer CCTV footage in a consistent way, using four families of codes: structural, operation and maintenance, construction, and miscellaneous.

Who inspects oil and gas transmission pipelines?

Transmission pipelines are usually inspected with in-line inspection tools run by specialist integrity firms. That is a separate industry from municipal sewer and storm work, and none of the companies on this page are listed for it.

Do I need a licensed contractor for sewer camera inspection?

For inspection alone, requirements depend on the agency and the contract, so check the bid documents. Once the job includes repair, lining or excavation, the contractor needs the right CSLB classification, and public agencies also require registration with the Department of Industrial Relations for public works.

Are these companies ranked?

No. They are listed alphabetically. Each one passed the same three tests, and the right one depends on your pipe, location and deliverable.

Why is Total UC not on this list?

Because Total UC publishes it. A company ranking itself in its own list is not a fair test, so we left ourselves out and kept the criteria public.

Where Total UC fits

Total UC is not on the list above because we wrote it. We are a Class A underground contractor in San Leandro (CSLB #1094194), and our crews camera-inspect sewer lines, run smoke, dye and pressure tests, and then dig or go trenchless when the camera finds a failed section. If your line needs an inspection before you decide on a repair, see our sewer line testing and inspection service.
