"Excellent service with the sewer repair and replacement. We decided to hire them to replace whole house pipes on our old home. Did the job at a reasonable price, just like the first job. Had one small leak problem under sink in guest bath. Texted at 1:00AM, he came at 10:00AM the same day. He fixed the leak at no cost. We have had no problems since. Now, that's what I call service. Also they are very personable and respectful young men. Thanks, Sewer Brothers!"

"Great service and work from Miguel and team. I would hire them again. What originally was a slow draining sewer line turned into a root infested backup. Miguel was able to scope the drain and visualize the root of the problem. They were prepared to start digging and had the tools and supplies on the truck to get the job completed. He clearly explained the discovery, repair, and installation process as well as potential other root intrusion spots. After the dig, the soil and grass was replaced and can hardly tell that any work was done. They also cleaned the dirt/mud on the concrete walk way. Thank you Miguel and team for the great work."

"Wesley was extremely responsive. He made all efforts allowing us to continue doing our business at home while he was assessing the problem, assembling his crews, and obtaining a City permit. We were well informed of the progress. His crew did an excellent and clean job, working long hours getting the job done. Including excavated to a depth of 10 feet, patched up our concrete driveway and patched up the AC roadway nicely. Wesley even found time to replace our kitchen faucet and under drain without extra charge. Don’t believe he would be the cheapest initial estimate you would get. We would definitely ask him for all future plumbing needs."

"I absolutely love that they work within your schedule to come out to perform services requested. I contacted their office late at night and they were able to schedule Chris the manager the next morning to provide me with a free second opinion. I had another local company that wanted to gouge me for everything that I had. This prompted me ti contact Renowned. After Chris did his free diagnosis, he went to me a reassured me that my issue was not as bad. I went ahead and had Chris and his team repair the section of sewer that only needed to be replaced. The entire sewer line did not need replacement like the other company stated it did.. Itâ s very hard to find trustworthy plumbers these days. Im so blessed I found mine."

FAQs for sewer main install, replace or repair projects in Diamond Bar, CA

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
