"This company is amazing! I just purchased a complete soft water and RO system to replace my 23 year old Ecowater system. Chris, who’s the company owner took the time to explain all my options in detail. He was extremely detailed and reliable throughout the entire process. Though they were booked out 3 weeks, he made special accommodations by installing my new system himself within one week of his initial home visit estimate. Chris was very meticulous to perfection. He’s fair and honest! Great experience throughout the process!!"

"The repair guy came within the estimated time and resolved my water heater issue, no charge."

"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."

"My water heater wasn't heating the water. Serviceman taught me how to light the pilot. He was very polite and helpful. I was very impressed with the service he provided."

"Response was amazing and fast. Arrived on time and kept me fully informed. Professional with complete set of moisture/ leak detection tools. Answered all our questions. Would love to recommend them."

"Prompt and efficient service. Very thorough in explaining the process. Friendly technician! Would recommend and use again (hopefully not for the same issue)."

"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."
