"Our sewer main busted and Oak Plumbing’s master plumbers Matt & Mike did a great job at digging down over 7ft to replace the broken section and also upgraded my single sewer main clean out which was nearly rusted through to a dual solid ABS clean out. And also I would like to add that Nate also did a great job at identifying our problem! Thanks guys! You’re AWESOME!"

"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."

"Superior plumbing has saved the day for me on countless occasions. I hit a sewer pipe with a lawnmower because it was sticking out of the ground and hidden by overgrown grass. I didn't know what it was, and sewage started coming out a few days later. I had another plumbing company come out and quote me $30k for a sewer lateral. I then had Superior Plumbing come out since they had recently installed a sewer lateral for my parents' house for much less. They said a piece of the pipe fell into the pipe, causing it to clog. They pulled out the piece, then cut the pipe to the ground and put a concrete cap that said "sewer," so I wouldn't hit it with the lawn mower again. It cost $1700 instead of $30k! Last week, the landscapers hit the cast iron sewer pipe coming from the bathroom outside. I immediately called Superior Plumbing, and they came out in 30minutes, as luckily they were close by. They addressed the issue and returned a few days later to replace the pipe with PVS, which proved to be very affordable. I then had them return to strap pipes under the house and install a water pressure regulator, as the water pressure was 95 when it should be 60. This could cause major problems with too high water pressure down the road with burst or leaking pipes. Look no further than Superior Plumbing for your plumbing needs!"

"They were amazing, giving us up-to-date info on the project and explaining our options to us when unexpected situations occurred (like finding out that the lateral sewer couldn't be connected to the main pipe because it was made of orange burg). They gave us a great price on the sewer as well. I'd hire them again in a heartbeat."

"He was here about an hour or two. We also asked him to go upstairs and figure out a leak in our master bedroom shower. He didn't find the exact leak but recommended putting some caulking in there. We decided we could try that ourselves. He was pretty knowledgeable. I was very happy with the results."

"Hello fellow consumers,
They came to do a water heater flush and replace a faucet - Angie's deal for $49.
They found some problems, which were valid.
But they used that as an excuse to charge extremely inflated prices.
I had to talk with my wife about the balance between not having them do the work now because their price was absurd vs. having another plumber come out, taking another 1/2 day off of work, to save a few hundred dollars.
Unfortunately my wife and I have been insanely busy due to her new job, so I just had them do the work, but I feel sick about it.
That is not what I want from a business to earn my loyalty, I will never use them again.
Readers may decide for themselves whether the price was fair and/or reasonable - 
What they did was (not included in the AL deal)...

Replaced approx. 20' of water line.  They used 3/4 copper 6 for replacement.  
Installed 3/4 ball valve and two supply lines.
Installed new Anode rod to replace the old one in the water heater.
Replaced approx. 10' of plastic laundry drain to foundation of house.

There were two guys, although for at least 70% of the time the assistant/apprentice just stood around.
So, including the time to do all work for the Angie's list deal - about 1/3 of the time - and the added work that they charged me for, and explaining why I needed all this, and to drink the coffee I made for them, the total time on site was about 3 hours.

I was charged a total, after a "discount", of $1,967.00.

Ultimately I paid almost $2,000 for no more than two hours of work, done almost entirely by one person, using materials consisting of 20' of copper 3/4' line, 10' of plastic drain, a valve, an anode rod, and two supply lines.
If that sounds good to you, by all means call up Benjamin Franklin, The Punctual Plumber.
But I will NEVER use them again, and I recommend you stay away as well.
Long time Angie's List user in Oakland, CA.

FAQs for sewer main install, replace or repair projects in Knightsen, 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.
