"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 plumbers from Superior Plumbing were excellent. They replaced and rerouted water pipes, changing from galvanized to copper pipes. The sewer lines in our house were repaired. They also replaced an aging hot water heater. The technicians arrived on time, worked diligently through the day, and were efficient. We added on the sewer repair which added an additional day. All work was completed within four days. I am impressed with their knowledge and workmanship. The technicians were tidy and removed all our old materials including the hot water heater. I would recommend Superior Plumbing and Drainage Co without hesitation."

Outstanding value. Highly recommended . I would call JD again in the future should I need any plumbing service."

"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.

"We asked another plumbing service to come last Friday and it was a complete failure.
The owner's son came and he brought a helper.The helper was very young - 17-21(?) and didn't speak English at all. It looked like he was getting trained. .They tried two different rooter sizes and then went to Home Depot get a really small manual one. The came back 2 hours later and still couldn't get it unclogged to as they were not able to get through or clear the P-trap. So they recommended cutting a hole in the ceiling in the room below and replacing the P-trap for $500-700 (!)
Plus when they left it was worse than before and they left a mess in the shower floor and walls - no clean up. NOT professional They didn't fix it so at least they didn't charge me- would have bee $150.
The next business day we called -Gladiator ( who we had used before) and they came the same day and the guy was done in 10 minutes - it was just hair in the drain! Less than $100.
Excellent work!"

"Three men were sent to get everything cleaned up in a day. They also arranged for the plumber to go and make the pipe repair the next morning so that my tenants were not inconvenienced for more than one day. They did a very good job cleaning and sanitizing the area."

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.
