“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.

“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.”Marlene S.

“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.”Vera N.

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.
