"I had a whole house water softener installed and I am extremely happy with the entire experience. Scott gave me a great price, half of what Culligan charged me. The installers, Brian and Thomas did an outstanding job with the install. They hid the pipes neatly and were very careful and respectful of my home. They explained everything in detail and answered all our questions. This is a great company to work with!"

"Just had my water heater replaced by these guys and honestly, they were awesome. They showed up on time and got everything done way faster than I expected. The whole team was respectful and easy to have around. They worked efficiently, cleaned up after themselves, and just made the whole experience stress-free. If you need a water heater replaced or repaired, I highly recommend these guys. I had called around a few places and Water Heater SOS was the quickest to get back to me with the best price as well. Solid work and just a great crew all around."

"More than exceeded my expectations. Very professional in every way from cleanliness to respectfulness. Needed a new water heater installed. Other companies wanted an arm and a leg while hermoso plumbing gave me a great deal with even greater service. In and out faster than expected with no hassles. Will definitely be giving them a call back for all my plumbing needs. Highly recommended."

"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."
