"Very happy with my new 3-stage whole house water filter/installation - topnotch!!!"

"I contacted Home Advisor on 11/15/16, to obtain some quotes for a whole house water filtration system. Gary, from Exclusive Water Systems contacted me, within 10 minutes of making my request. He was able to give me a fair estimate, after our discussion via the telephone. Gary was professional and able to complete the installation in a few hours. I was glad his company was recommended through Home Advisor. I would definitely refer him to family members and friends, who are in need of quality services for installing a water systems."

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 have a tankless water heater that was giving an error code and i had no hot water! The tech that came out was very nice and knowledgeable. Im glad to report i now have hot water again. As a side note I talked with the tech about water treatment options and a RO system and as long as my husband agrees I will be having them install both items!!"

"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."
