"I had an excellent experience with my plumber Gary and couldn’t be happier with the work. He completed two major projects for me — a full repipe under the house and a kitchen drain reroute — and everything was done professionally, efficiently, and with great attention to detail. He took the time to explain the process clearly, answered all my questions, and made sure everything was done correctly and up to code. The work area was kept clean, the timeline was exactly as promised, and the pricing was fair with no surprises. It’s hard to find a plumber who is honest, reliable, and skilled, but Gary truly checks all the boxes. I highly recommend him to anyone needing plumbing work done right the first time. I will definitely use him again for future projects."

"The technicians who completed the work were excellent ? I would rate them 5/5. However, the office team that contacted me did not provide an accurate quote. I was assured that, as a first-time customer, I would receive a favorable price, but this turned out to be a misleading promise made only to secure the business. Relying on that assurance, I canceled another professional and proceeded with Stellar Sewers Coastal Plumbing, which I now realize was a mistake. Due to the urgency of the situation, I had no choice but to accept the higher price. While the field staff performed well, the misleading communication from the office was disappointing. Unfortunately, based on this experience, I cannot recommend this company to others."

"Jose came out to trouble my 6 year old water heater which stopped heating and would not respond to my efforts. After a long and thorough attempt to fix the situation, the heater declined to participate. Jose outlined my options and explained in detail what he wanted me to know before deciding to purchase a new system. Once I decided, Jose worked out a plan for me. He made sure his supplier was open on Christmas Eve so he could pick it up and install for me the same day. Jose returned early the next day with his partner to change out the old system (from 2nd floor) and haul the new tank up those pesky stairs. Super Heroes, absolutely. They worked diligently until the job was completed. Jose explained the features/answered my questions and gave me a very fair price. I definitely plan to call him for future needs. He's the best. I sincerely urge you to call Jose for your next plumbing debacle. Kudos. -- Dawn"

"Impressed! Johnathan and Gio were so professional, courteous, and sympathetic to our situation. I had the unfortunate experience of a root intrusion in my sewage drain and these guys made it right! They worked hard and made sure we still had use of bathrooms during the project. It wasn't the cheapest but when I saw the skill level everyday, I believe I got what I paid for and this isn't something you want to be cheap on when its under the slab! Top notch all around and the attention to detail was commendable, well done guys!"

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