I was extremely pleased with the Certain Services technician and his approach and knowledge. He took the time to explain to mehow the water treatment system operated and what needed to be done as regular maintenance. It is never a good experience to learn you are in need of a major component replacement, but the technician fully explained our options and the impact of our non-functioning water softener.We will be making a decision very soon on replacing the water softener and based upon our initial exposure, it will Certain Services who does the work.1/11/2022I have been extremely pleased with the service provided by Certain Services. I believe you provided the services we needed without trying to up-sale us and your service personnel have been professional and personable.I like the way you do business and in the future I will call Certain Services for our water and plumbing needs.09/21/2022I continue to be very pleased with Certain Services. Their field technicians are prompt, professional and courteous. Scheduling was convenient and seemed well managed.04/19/23Certain Services came through again. I had a well head accident and needed emergency service. Certain Services responded and fixed the well head issue and ensured the repair was in good shape before they left. Thanks again

Our problem was solved quickly. Cody was great. He educated us on a few things since we are still in the learning process. Price was reasonable considering it was an emergency visit.

Got our RO system about two years ago and are very pleased with the system as well as the continued excellent service they provide. Certain Services is the best choice we made in upgrading our home since we moved in. Can’t recommend them enough.

I'm expressing my gratitude to Mrs. Helen Wayne who helped me trade in crypto/forex with my little capital of $700 which earned me $7,900 after 6days of trading. I was referred to Helen by a friend and all her trading techniques and withdrawal is easy. You can reach her for your best trading experience.

We've been Certain Water Services customers for about 10 years. Recently, we accidentally damaged our system when dragging the trees that fell during Hurricane Ian. Cody was out within hours and got our water running again. They've never let us down!

Certain Services did an excellent job repairing and replacing what was needed for our water system following Hurricane Ian. We were scheduled a month out initially but as soon as there was an opening they called and moved up the date. Joe was our technician and he explained everything that was going on and what was needed to get our system running. He was quick and professional. He responded quickly to texts and calls, something you don't see much these days. I would recommend Certain for all of your water needs

Joe did a great job for me, we just purchased a new home and needed to understand the system, how it works and anything that needs to be looked after on a regular basis. Joe explained everything and was very knowledgeable about the system. Joe and Certain Services are experts on water treatment systems
