We awoke one morning to no water. I called Certain Service. They responded quickly. They had a tech in the area. After completing that job,Nick responded to our call. He immediately identified the problem and made the repair. He then checked all the equipment and found our softener was not working. Another quick fix. He answered my questions and was very explanatory on what he was doing. I will “Certainly” use this company without hesitation. We awakened to water this morning! Thanks Nick and Certain Service.

We've been using Certain Water Services for five years. They helped us keep our old system going as long as possible. I really appreciate that they understood our tight budget and worked with us. Finally, the system failed once and for all, and we got a new one. The price was fair and they set us up with easy financing. The new system is awesome! No more sulfur smell, no more skin rashes and our hair looks gorgeous! We LOVE Certain Water Services because we know we can always count on them! Highly recommended by me!

I had not had maintenance done on my water treatment system since its installation several years ago. Certain Water Services' tech, Cody, was punctual, friendly, answered all my questions in a most patient and knowledgeable manner, and has my system performing like new. Moreover, Certain's friendly office staff set me up with a reasonably priced maintenance schedule. I look forward to a mutually beneficial business relationship.
