We had a awesome experience with Certain water services, they installed a reverse osmosis system in our home. After living in Wisconsin with great water I was very disgusted with the salty Florida water. The Certain team changed that for me. I love my water, no more sulphuric smell and best of all it taste amazing. I feel great knowing I’m drinking clean water. It’s a game changer for me living in Florida. The team they sent Nick and Cody were professional and explained everything to us even in the 90 degree heat. We are happy for making the choice to have the Certain Water services team with all their expertise install our new system. I did a lot of research prior to choosing Certain water services and have no regret they impressed me with all their knowledge of the water in Florida. I now LOVE our water. Thank you Bill and Chris.

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.
