“I am in the real estate business 31 years and have used many water testing and treatment companies. Since using Dierolf I have no reason to use any other company. They are always responsive, efficient, customer oriented, and honest.”

“Very honest, very knowledgeable! I recommend them to all of my clients because of Mark’s integrity and quick turn around time. He won’t try to sell you anything you don’t need, but if you need anything, he will help you to make the best choice for your circumstances!”
Very fair pricing, very easy to work with, always helpful and great customer service and responsiveness. So far I've had a sanitizer and neutralizer installed and I haven't had any issues with my equipment. The installation looks very clean and tidy as well.
The 2 young men were excellent! Very knowledgeable and professional. They explained every inch of the process. For us it was great. I am happy l selected Dierolf for our water softner. They not only treated us like family their product far surpassed others. Hats off to a job well done. A big thank you guys.
Very friendly, informational, and sincere. He answered all my questions. He gave me helpful tips and what I can expect to happen with my water system. He cleaned up the area where he was working. I would recommend Matt to my friends and family. Great job guys
