"Jess helped us out with the huge job of replacing the entire sewer main pipe from under our house to the sidewalk given that our old cast iron pipes were corroded and kept getting blocked by roots. This was a 3 day job involving a multiple person team. We went with Jess given that his estimate seemed fair and beat out other competitors. The work ended up being more labor intensive than anticipated, as digging to the city sewer line, which should have taken hours, ended up taking a day and a half due to unseen gnarled roots and cement in the soil. Despite this, Jess and his team worked diligently, showed up when they said they would, and finished on time. They were courteous, professional, and very hard working. I will not hesitate to contact Jess for our future plumbing needs. Photo shows old pipe vs new pipe."

"Short version:
They got the job done, but it took two visits and cost about 2-3 times more than it should have because they initially arrived with the wrong equipment and then recommended an unnecessary, expensive video scan.  The extra cost was due to their error and they should have covered at least some of it (if not all) but they refused.

Details:

Our sewer line backed up between our house and the street, and so I called In and Out to clear it.  They arrived with nothing but a hand snake because supposedly other equipment was in the shop.  The plumber was able to (temporarily) clear the obstruction with the hand snake.  Charge: $250, which also included cleaning the trap in one of our interior sinks.  So far so good (although if I'd known they'd come with just a hand snake, I would have done it myself...)
Two weeks later, the line backs up again, because the hand snake only punched a small hole in the obstruction rather clear it completely.  I called In and Out to come back with the correct equipment.  

This time they arrived with the proper equipment, including the full sized snake and water jet to clear the roots.  Given the previous failure to remove the blockage, they recommended sending the video camera down the pipes to diagnose the problem.  Problem = roots from the trees near the sewer line (surprise!).  They used the snake + water jet to remove the roots and clear the obstruction.  Now everything works.  Bill = another $775.  

 Why do they get a C grade?
Issue 1: they refused to refund any of the money from their first, failed intervention.  If they'd just arrived with the right equipment, we would have removed the roots on day one, sparing us another sewer back up and another expensive visit.  They brought the wrong equipment and didn't solve the problem -- there should be at least a partial refund.  Even an apology would have been nice.  But I didn't get either.   instead, we come to Issue 2

 Issue 2:  when they came back, they recommended an unnecessary (and very expensive) video scan of our system which just turned up the obvious problem of roots from the nearby tree.
Total cost was over $1000, for a job where most plumbers would have just gone in with the big snake + jet on day one and knocked out the roots for $250-400.   In and Out ultimately fixed the problem, but we had to endure 2 days of sewer back up and paid 2-3x what we should have.

On the plus side, they were always very prompt, professional, and friendly in person (aside from issues noted above)"

"We recently had Major League Plumbing & Rooter complete a sewer main repair at one of our commercial properties, and we couldn?t be happier with the service. From the initial inspection to the completion of the repair, their team was professional, knowledgeable, and extremely responsive. They clearly explained the issue, provided honest recommendations, and kept us informed throughout the entire process. The crew arrived on time, worked efficiently, and completed the repair with minimal disruption to our business operations. Their attention to detail, cleanliness, and commitment to quality workmanship truly stood out. Commercial plumbing issues can be stressful, but Major League Plumbing made the entire process smooth and hassle-free. We highly recommend them to any business or property owner in need of reliable, professional plumbing services. Thank you for a job well done!"

"Can not imagine a better response, starting with my call for assistance, response time and how the technician, Tad methodically diagnosed the problem. We have an obscure kitchen fixture that required service in Feb 2019. Under warranty the problem was easily diagnosed by me, a problem possibly caused by me and a replacement part sent and installed by Albert Nahman team. Problem: I broke the faucet cartridge. Current Problem: restricted hot water flow in this kitchen sink only. Turns out the new cartridge part is now malfunctioning. I called and Tad arrived taking a step by step approach ruling out possible causes: a clog here or there, build up of sediment, or blockage in the lines or cartridge. The company that sells the product got on the phone with Tad and they collaborated on the problem and the tech person gave Tad one more thing to try. After the collaboration it is agreed, problem persisted and therefore that new cartridge part is now malfunctioning and will be shipped free of charge in two days. Thanks to all, who made this possible and I trust we will have Tad here again soon to finalize this fix. BTW, cost of service was less than expected given going rates for such a call lasting in excess of one hour. Another comment, spending time with Tad during the repair was a pleasure to have him explain, collaborate, listen and just chat. Questions on who to call next time, no question who I will call next time. I have read criticism of costs: In the Berkeley area "How much does it cost to hire a plumber? Some plumbers have a minimum fee for a service call. They might charge anywhere from $175-250 to come out and give you a consultation. Plumbers may give you a general service rate of $128-148 per hour when there are a lot of unknowns about a project and they aren't sure how long it will take. Some charge a flat rate for their plumbing services. For example, you may get charged $175 for a sink or drain cleaning, while toilet installation costs $500." Today costs are upfront, same as charges in Feb, $69 to arrive and assess the problem. Here in excess of one hour for $129 minus $25 coupon, total charge $173. I am ok and I expected these costs. If I was in Philly, where I grew up, I could call an uncle or cousin and get a better rate, a family rate. This is going rate for our area."

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend."

"Bay Area Pro Plumbing did an outstanding job replacing our water main line. From start to finish, the team was professional, knowledgeable, and very efficient. They explained the entire process clearly, completed the work on time, and left everything clean when the job was done. The quality of workmanship was excellent, and we immediately noticed better water pressure throughout the property. It?s hard to find honest and reliable plumbers these days, but these guys truly exceeded expectations. Highly recommend Bay Area Pro Plumbing for any water main or plumbing work!"

FAQs for sewer main install, replace or repair projects in Redwood City, CA

Most trenchless sewer line replacements can be completed within one to three days, though this varies based on your situation. Simple repairs on accessible lines might be finished in hours, while complex systems or challenging soil conditions could extend the timeline. The reduced excavation requirements result in faster completion compared to traditional trenching methods.

Trenchless pipe lining may reduce the interior diameter of your pipes, which could affect flow capacity in already narrow lines. This method also requires the existing pipe to maintain sufficient structural integrity to support the new liner. Severely collapsed sections, major joint separations, or completely misaligned pipes might not be suitable candidates for lining and could require alternative approaches.

Trenchless sewer pipe liners are rated to last up to 50 years when properly installed and maintained. Actual longevity depends on installation quality, usage patterns, and environmental factors like soil movement or tree root intrusion. Regular maintenance and avoiding problematic disposal practices (like flushing non-biodegradable items) can help maximize your system's operational lifespan.

Trenchless technology availability varies by region, with greater accessibility in metropolitan and suburban areas where specialized contractors operate. Some rural locations may have limited access to trenchless equipment and expertise. Local regulations and soil conditions also influence availability. A professional assessment of your property and local contractor options will determine if trenchless methods are feasible for your specific location.

Professional video inspection provides the most reliable assessment of whether your sewer issues suit trenchless repair. Generally, pipes with moderate damage, like small cracks, minor leaks, or partial blockages, respond well to trenchless techniques. Completely collapsed sections, severe misalignments, or extensive structural failures might require traditional excavation. Consulting with contractors who offer both methods ensures you receive unbiased recommendations.

Quality trenchless sewer replacement often includes a workmanship guarantee from the contractor. The specific terms vary by company and region, but many professionals stand behind their installation for at least one year. Material warranties may extend longer, depending on the pipe products used. Always request written warranty information before hiring, and understand exactly what's covered and what might void your protection.
