We were completely happy with the sales and service experience with this company, and after having our new system in service for three weeks now, we are delighted with the benefits of soft, clean water. Everyone we dealt with was courteous, knowledgeable, and professional. We never felt pressured to buy more system than we needed, and I felt the cost of equipment and installation was fair and reasonable in comparison to other options I researched. At this point, we are very satisfied customers.

Bill came out and tested our water and answered all my questions. We decided on a water softener and a reverse osmosis. The softener already has made a huge difference in our whole home! The reverse osmosis water taste great, no more bottles of water! The whole team is great, they have also serviced a few family members of mine, and I am happy we decided on using Certain Services!

We had a new sink installed as well as new plumbing underneath. Joe did a wonderful job and was very thorough. He explained everything in detail. We would definitely use Certain Services again in the future.

I recently called Certain Services to have my Outside water system inspected and cleaned. Amy was very professional, nice and helpful. Nick arrived well within the two hour window and is not only an excellent technician, but took the time to answer all my questions about the system, explaining everything he was doing along the way. I never realized the ‘chemistry’ behind the water system. Nick is extremely knowledgeable, and worked hard to clean the large tank. I am happy I have found a company I can rely on to inspect/clean in the future! I have had two other company’s in the past, and neither took everything apart to inspect. ⭐️ ⭐️⭐️⭐️⭐️

The technician showed up when scheduled, had good knowledge of the system, checked it out and replaced the filter. He took the time to explain the setup and maintenance to me.Bob

They came, they saw, they cleaned and inserted new water filters, exactly what they were hired to do; no fuss, no mess, no problems. They are on yearly call to continue their work at my house.

Bill Certain is the owner who is very knowledgeable on local water conditions for all your conditioning needs. His store and Shop are impeccably clean for a water treatment company. He frequently has classes for all of his employees so they are kept abreast of changing water conditions. The type of equipment he uses is top quality but that's what you want for getting good clean water!

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.
