"Service Flow Plumbing did an excellent job flushing my tankless water heater at a very reasonable cost. Rose provided outstanding customer service from start to finish, and Andrew—the technician who performed the flushing—was extremely professional, knowledgeable, and sure to explain everything clearly. The whole process was smooth and stress-free. Highly recommend their team!"

"I recently had the pleasure of working with Joshua at Diamond House, and I couldn't be happier with the experience. From start to finish, he demonstrated professionalism, efficiency, and excellent customer service. My pipes were old, corroded, and causing issues in almost every part of my house from faucets to my water heater and water pressure. When I reached out for a repiping project, they responded quickly and scheduled an in-home consultation right away. Their team was punctual, arriving exactly when they said they would. Joshua walked me through the process of replacing my aging pipes and even gave me a few options that fit my budget. If any unexpected issues came up (as they sometimes do with older homes), he discussed them with me before proceeding. This level of communication gave me peace of mind. Although repiping is a significant investment, I felt that their pricing was fair for the high level of service I received. The long-term benefits of upgraded plumbing have already made a difference in my water pressure and quality. They also provided a warranty on all of their work and included yearly maintenance on my water heater and water filter/descaler. Diamond House Plumbing exceeded my expectations, and I would highly recommend them to anyone in need of repiping or other plumbing work."
