Sewer Line Replacement in Rancho Cucamonga

Future-Proofing Your Home with Modern Sewer Solutions

A sewer line failure is one of the most significant challenges a property owner can face. Whether you are dealing with a collapsed line, persistent root intrusion, or pipes that have simply reached the end of their lifespan, the decision to replace a sewer line is an investment in your property’s future. At Scott McLeod Plumbing, we focus on providing sewer line replacement services that prioritize durability, clear communication, and as little disruption to your daily life as possible.

Since 1980, we’ve worked with homeowners, property managers, and organizations across Rancho Cucamonga and the Inland Empire. Our A+ rating with the Better Business Bureau reflects decades of consistent service and is supported by our history of completed projects for the City of Rancho Cucamonga and large-scale infrastructure work at Chaffey College. From private residences to public facilities, we bring a steady approach to every sewer line replacement.

We also understand that sewer work can be a major expense, which is why we provide free estimates, flexible payment plans, and financing options. For urgent issues, 24/7 emergency response is available, so you aren't left without essential services.

Our Approach to Sewer Replacement

Replacing a main sewer line is a significant project that requires a "measure twice, cut once" philosophy. At Scott McLeod Plumbing, our process begins with a comprehensive diagnostic evaluation. Before we ever break ground, we use advanced tools to determine the exact depth, material, and condition of your existing pipes. This allows us to see if the line has simply reached its age limit, has been crushed by soil movement, or is being compromised by tree roots. By gathering this data upfront, we can provide you with a fixed, transparent estimate and a clear plan of action.

Once we understand the scope of the damage, we determine the most efficient replacement method for your specific property. While we prioritize trenchless sewer replacement to protect your landscaping and driveway, some situations, such as a completely collapsed or "back-graded" pipe, may require traditional excavation. In those cases, our team works with surgical precision, removing the old sections and installing modern, high-durability piping that meets or exceeds current building codes. 

Modern Sewer Solutions: The Trenchless Advantage

The most common fear with sewer replacement is the thought of a backhoe tearing through your landscaping or driveway. Our team aims to minimize that impact by utilizing trenchless sewer replacement whenever the situation allows. This modern method allows us to install a new, high-density pipe or durable liner through your existing line using small access points.

This "pipe within a pipe" approach is often faster than traditional excavation and significantly reduces the need for expensive yard restoration. For properties with mature trees, custom hardscaping, or commercial parking lots, trenchless replacement offers a permanent solution that preserves the beauty and function of your property.

    I highly recommend Scott McLeod Plumbing.
    “Heads-up Rancho Cuc residents! I was a first-time customer of Scott McLeod Plumbing this week, and had the good fortune of being assigned to Joseph Alarcon. What a blessing he is....very professional, kind, efficient, and knows what he is doing. He even cleaned up the work area after completion! I was extremely satisfied with the services.”
    Judy M.
    I could not give this more of a recommend.
    “I needed my mom’s garbage disposal fixed for the holidays. Peter and his associate came, and really did their due diligence. They examined everything, helped me look at prices, and overall were just kind and helpful.”
    Wyatt L.
    I appreciate the service and would recommend to anyone.
    “Contacted Scott McLeod after my Insurance sent out some bozos who quoted me $6000 to include jackhammering my floor and my shower. Scott McLeod plumbers came out, found the problem which was minimal and required no jackhammering. They were clean and professional, and I would use them again in a heartbeat Thank you for an honest job well done. I appreciate the service and would recommend to anyone. Very friendly from the time of a phone call till the service was completed. Definitely will use again. Eli was awesome.”

    These guys are amazing and we will definitely be a customer for life!
    “Dustin came out to help us with our hot water going out and showed up right on time. He fixed our issue in about ten minutes and was super honest about what went wrong and how to prevent future issues.”
    Lila K.
    Teddy and his assistant were very professional and polite.
    “After completing service they made themselves available to answer other plumbing issues I had throughout the house. They spent time walking to other issues and helped troubleshoot those issues.”
    Ivan C.
    These guys were prompt and thorough.
    “Glad I reached out to these guys when a family friend needed help with plumbing issues that had them shutting off their water and heating water just to shower. These guys were prompt and thorough, and about $1K cheaper than another local shop (not naming names, but shame on you, we thought you’d be better). Funny enough, this company is also family-owned, just more modernized and organized, which is a huge plus!”
    Monica G.
    Thank you for a great job.
    “I called on a Saturday afternoon and they were able to come out within an hour. Peter came out and did great work. Explained everything clear and didn't try to over sale us on extra services. He was very professional and did the job quickly”

    I am so happy to have found Scott McLeod Plumbing and will stay with them for all our future needs.
    “We had an issue with the plumbing in our master bathroom develop over the weekend. This had a sudden onset and very odd pattern. On Monday AM we called Scott McLeod Plumbing and to my surprise, they were able to send out a team a few hours later. Based on our description of what was happening, and his inspection of a few things, Teddy deduced immediately what the most likely problem was and explained to us the sequence of events that caused our problem. It was so logical and was communicated to us so clearly that we immediately felt complete trust in the solution he proposed. He was very obviously a complete expert. The cost proposal for all the work was very reasonable. He and his assistant spent the rest of the day solving our problems. It was such a pleasure having two such lovely people take care of our issues. I have used another top-rated local plumbing company in the past and although they did good work, I felt like their pricing was very high.”

FAQs

How long will a new sewer line last? 

Modern replacement materials, especially the high-density polyethylene used in trenchless lining, are incredibly durable. Many are rated to last 50 years or more and are virtually immune to the corrosion and root intrusion that plague older clay and iron pipes.

Is a replacement always better than a repair? 

If your pipe has multiple breaks or is "bellied" in several places, recurring repairs become a "band-aid" fix that costs more over time. A replacement provides a clean slate and long-term peace of mind.

Do you handle commercial sewer replacements?

Yes. Scott McLeod Plumbing manages sewer infrastructure for retail spaces, offices, and industrial properties. Our experience with organizations like the LAPD and Southern California Edison ensures we can handle the high-volume demands of any commercial site.
