    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 highly recommend them.
    “Dylan and Michael, two plumbers of McLeod plumbing came to my house and redid the plumbing in my shower bathtub. They were polite. They were efficient. They were very very tidy and I enjoyed meeting them both and I was extremely pleased with their work.”
    Jean D.
    We are forever grateful for you guys!!!
    “I called 20 plumbers and seen 4 and Dustin from Scott McLeod the best plumber in the world. I cant thank him enough for how much he had helped us and eased our concerns. He went above and beyond and we are a forever customer and will always always go to him with this company. He is on time, honest and awesome at anything to do with plumbing. He knows his art and we have never seen a better man to do what he does. Also wendy the receptionist is super nice too!”
    Betty S.
    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.
    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.
    I highly recommend them to anyone in need of trustworthy and skilled plumbers!
    “Scott McLeod Plumbing showed up in my time of need and truly saved the day. They were helpful, reassuring, and professional during a very challenging situation. I had previously worked with another plumbing company that left me uncomfortable with some questionable accounting practices, but Scott McLeod Plumbing completely restored my faith in both honest and quality service. From start to finish, everyone who worked on our project—Teddy, Peter, and Michael—was pleasant, professional, and respectful of our home, including our landscaping. They completed the job quickly, which was especially important since it was a time-sensitive repair, and their attention to detail and care were exceptional. I am so grateful for their expertise and kindness. Thank you, Scott McLeod Plumbing, for turning a stressful experience into a positive one.”

    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.”
    Happy Customer
    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.
    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.”

Why Scheduled Maintenance & Inspections Matter for Your Business

In a commercial environment, the cost of prevention is always lower than the cost of a catastrophic failure. Fontana’s hard water (8.6 GPG) is particularly aggressive toward commercial-grade boilers and fixtures, leading to rapid scale buildup that can choke your system. By scheduling routine inspections and "plumbing health checks," we can identify early signs of pipe corrosion, monitor water pressure, and perform mineral descaling before these issues lead to an emergency shutdown.

Our comprehensive inspections include video pipe auditing to catch sewer line shifts and thermal imaging to spot hidden leaks behind warehouse or office walls. This proactive approach extends the life of your equipment and ensures that a simple $100 fix doesn't turn into a $10,000 disaster that halts your operations.
