    “We are very pleased with the work that Brandon did replacing our toilet. The entire process of working with him was easy and pleasant. He was prompt, informative, polite, and respectful. Their pricing was also more reasonable than the other quote we got.”

    In future plumbing emergencies we know who we will to trust call!
    “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.”

    “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!”

    “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.”
