"Andrew was our plumber and also the owner of Service Flow Plumbing. He is everything you want in a professional tradesmen. He was polite, prompt, respectful of my home, thorough, very efficient, and was very generous with his time answering all my questions and showing me how to fix my next faucet handle. His rates are reasonable especially when you consider the level of attention he gives to your problem. I'm telling my family and friends about him & his company because service like his is unfortunately too rare."

"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."

"My under the sink RO system stopped working. Daniel came and we realized it needed to be replaced. He made a recommendation and bought all parts for me. It was a smaller direct system that works best for my needs."
