About Certain Services, Inc.

Certain Services, Inc. is a family-owned and operated water treatment, plumbing, and well equipment service company. From the beginning, Certain Services, Inc. have devoted themselves to providing top-quality service to their clients in Southwest Florida at a fair price and they hold true to those values today. Customer service, integrity, and all of the forgotten values of the past are what you will receive when working with Certain Services, Inc. They have been involved in the water treatment business for over 20 years and service all makes and models. We offer a 100% satisfaction guarantee.

Certain Services, Inc. was started in 2009 by Bill and Chris Certain as Certain Water Service. Bill started out as the soul service tech/sales rep/parts runner/installer (in other words he did it all). After about 2 years they added their first technician and soon after they added Kelly (their daughter) to answer the phones, dispatch, and do data entry.  From there they bought out the residential side of a reverse osmosis (RO) company called, Harn RO. Mr. Harn had been building his drinking water systems for 30+ years and had evolved into a company that built municipal RO plants all over the world. The Certains took over the business with the goal of focusing on customer service.  This turned out to be a huge blessing to the Certain family and the business.

Since then they have added 2 other technicians, another office staff member, and a part-time sales consultant recently, Chris Certain left her position as a senior staff accountant for Goodwill Industries and started full-time at Certain Services. From 2013-2016 Bill Certain served on the Florida Water Quality Association board while also pursuing his plumbing contractor certification.

Certain Services is now a state-licensed plumbing contractor and an authorized WaterCare Dealer since 2014. Along with WaterCare products, they also sell and service the CertainFlow line, their in-house built reverse osmosis systems.

At approximately 5:15 pm I turned on the water and got nothing. I checked the well pump breaker and everything else I knew to do but without success. I called Certain Services and told them my dilemma. They said a technician would contact me soon. I was a little skeptical that we would get someone this late in the day. 15 minutes later I got a call from Joe Puga of Certain Services. He asked me to check a few things so I wouldn’t have to pay a service charge for something minor. There was still no water. He stated that he would be there shortly. At approximately 6:10 pm Joe showed up. He looked at a couple of things and then determined that the well pump needed replaced. He explained the process and the price. He also stated that in a few rare cases the pump is stuck and needs a special technician to drill it out which would be more money. He wanted to make sure I knew everything upfront. He started working on the pull the pump and 15 minutes into it he said the pump is not stuck so we were good. It started getting dark but Joe kept going to get the pump replaced. After he finished we began talking about a whole home reverse osmosis system. He described to me how my system would be replaced and how the equipment would fit. He gave me an estimate and everything.I am very happy with the incredible service we received from Certain Services. Joe is a valuable asset to this company and is not only professional and highly skilled he very friendly and very pleasant to speak with. Big kudos to Certain Services on a job “well” done!

I have a very nice completely 100% custom built reverse osmosis filtration for my house in an area with very hard sulfuric water. I’ve had to make a few service calls just for maintenance but i had an issue with where my well draws from the ground out it my yard. The call I requested was given to a service tech named Joseph who has been here multiple times before. What i though whats going to be a huge job he made look SOOOO easy, like unreal how easy he made it look. He had it repaired an service in under 2 hours, and to top it off he held a conversation and was teaching me about my system well enough to keep me out there in the FL summer heat with him on my first day iff in over a week! So thats worth something alone! It was $400 but you get what you oay fir with this company. Good work isn’t cheap and cheap work isn’t good. I give this place a try 10 out of 10 across the board.

So hard in SW Florida to get a contractor to even call back. Certain Services was right there and came out when they said they would. Were on time. Fixed my irrigation pump. Was a simple fix. Even showed me how to do it myself in the future and gave me options for replacing the tank. The technition didn't try to upsell and get me to spend money. Gave me options and was excellent. Hard to find a company anymore that does the right thing. This company is the way to go for well pump needs. Very pleased.

my water system was not working well. I looked at very good reviews for Certain. The tech Joe came to check it out and then he gave me the cost. He cleaned everything and got the system working better than a lot of time He took my information and he will be bringing salt and checking over the system. Finally i have clear water. I am happy

"Hey Bill & Chris! Regarding our service call yesterday, our overall experience was awesome. A personal call for service, with a technician arriving quickly! Nick was very friendly, thorough and professional. Very quick with his diagnostics and repair. And, very reasonably priced! Every experience we’ve had with the Certain folks has been incredible, but each time you seem to go above and beyond the last. And, most importantly… perfect water!! Thank-you!" - Steve Donaldson

What is the best water purifier?

The best water purifier is the one that meets all the needs of your home. Depending upon what is found in your home water test, a basic water purification system may suffice or you may need a more robust system for high levels of contamination.

What is the best way to purify water?

The best way to purify water is via a multi-step/ multi-filter water purification system. Each step/ filter will do different things to purify your water. If you have hard water, you’ll want a water purifier that has a softening step/ filter. If you have water contaminants, you’ll want a reverse osmosis step/ filter. If you have high levels of bacteria and/or viruses, you’ll want a uv step/ filter as well. It all depends on the needs of your home’s water.
