“Helped out with my washing machine and were more than fair regarding pricing. They came in, did their thing and since I was working that was a blessing because I didn't have to manage it. Complete professionals.”Erika B.

“What an amazing day, who can say that after a water heater breakdown? We called, and you guys didn't let us down. 20 minutes after our call, the service repair men were joyfully, professionally ready at my door. They examined, explored, determined what happened to our 3 year old Water heater, found our house regulator valve shot, corrosion was filling the diaphragm of it, preventing it from regulating our water pressure. Because our water pressure was over 100 psi, our 3-year-old water heater inner liner was torn through, and the entire tank was emptying around the lower seam. Everything was shown, explained, and once they learned that my husband is 100%disabled vet, and currently recovering from shoulder surgery. The discounted price met our ability, and 2 hours later, we have a new water heater and water regulator, and are happy that this company met our needs.”Pamela T.

“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

“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.

“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.

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.
