"Josh and his helper did a great job plumbing in our new construction home, including putting in a whole home water purification system, and a 400 gallon holding tank since we live on a high ridge. Love how our house has turned out and they are hard workers!"

"We were having problems with our hot water heater and Karl and Mike were able to come out the next morning. They were fast, kind, respectful, and did a great job replacing our water heater. They even came out the next day on a Saturday when we realized that our pressure regulator failing was the cause of all of our problems! I would highly recommend them as they are trustworthy, quality guys and professionals."

"Bobby was quick to respond to my texts and gave quotes so I would be prepared with payment. He and Charlie arrived minutes before he said and the whole job only took an hour and a half. So clean, couldn't tell he had been here. Professional, friendly and tried to save me money where he could. I'm thoroughly impressed! I highly recommend the Water Heater Pros!"

"Overly expensive charges for replacing our water heater and water pressure regulator. Two weeks after installation my basement was flooded again and the water heater installed was the cause. When called out to fix the problem the tech flooded my basement again on the repair. The installer and assistant were nice people and he was the plumber who came to repair it. The owner is a good guy whom I had used once prior on a small job and I really liked him. I was not pleased with his demeanor this time on the first installation or the text showing him pictures of the rupture. I would not have written this if I didn?t know the cost to him of the replacement water heater compared to what we paid. It was WAY over on the labor which much of was waiting for parts not on their truck. That?s not the customer?s fault."

"Dustin and Austin are very knowledgeable about plumbing. They did an excellent job removing my old hot water heater and installing a new one with the addition of an expansion tank. I appreciated their promptness on the job and the cleanup afterward. Total Customer Satisfaction!"
