Whole Home Filtration Benefits Your Appliances, Your Home, & Your Health!

We help local families remove up to 99% of contaminants from their drinking water while also filtering the water for their entire home so you can enjoy luxurious baths free of chlorine, softer skin, silkier hair, whiter whites, brighter brights, & spotless dishes and stemware. Plus, you’ll love cooking with our water as you’ll taste more of the food’s flavors and fewer impurities.

Our systems are proven to remove up to 99.9% of common contaminants so you can be worry-free when it comes to the water going into your body and on your skin.

Just think of all the things water touches: your water heater, boiler, washing machine (your family’s clothes!), dishwasher, your body, food, etc…


If you can picture your life with less time spent cleaning and worrying about what’s in the water you drink, then you can picture your life with water treatment from the professionals at Certain Services, Inc..

Get Great Water At Every Tap with Whole Home Filtration

If you’re like most folks, your home is one of the largest investments you’ve ever made. It takes so many little details all working together in perfect harmony to ensure your home runs like a well-oiled machine.

Here are three ways Certain Services, Inc. can take care of your water, so you can take care of you and your family:

Chlorine is a nasty but necessary chemical used to disinfect municipal water supplies. Although it’s good for killing bacteria, it’s bad for your skin and your health. Over-the-counter chlorine filters for your shower and sink only can do so much before they themselves get overrun with bacteria and buildup.

Our unique Whole Home Chlorine Filter removes chlorine for the ENTIRE home so you never have to change another filter again. Plus, it cleans itself automatically and, unlike your mother-in-law, is seriously low-maintenance.


We all know the telltale signs of hard water. Just like flies in the springtime, those pesky hard water spots, scale in the bathtub, and embarrassing cloudiness on the wine glasses keep coming back again and again.

Certain Services, Inc. offers a variety of hardness removal systems that ensure sparkling drinking glasses, clear shower glass, soft skin and hair, and lots of suds in your bubble bath (of course now you’ll have time to be IN the tub, instead of scrubbing the tub).

These days we can spend hours, if not days, pouring energy into worrying about the chemicals and contaminants we consume. As an increasingly health-conscious nation, we all are becoming aware of the necessity of clean drinking water. We’ve all heard the statistic that water makes up 70% of our bodies (studies show in babies and small children water can make up even more).

We had our well pipe burst on Wednesday after 6pm, panicking I didn’t know who to call, I searched in the area and found Certain Services. The after hours answering service was quick and extremely easy to talk to. Knowing it was valentines Day and most people are out, I didn’t expect a call so quick from their technician. Brian was able to help me on the phone get my water turned off and told me his boots just needed tied and he would be right there. Shortly after, he showed up ready to work. It had already started to get dark so we knew time was limited. He was able find the issue, work fast, and unfortunately due to it being to dark he wasn’t able to finish that night. Thankfully he retuned first thing in the morning and fixed us right up! We are very impressed with his time, ability, and commitment to making sure this was taken care of and fast! If you need a service that has quality customer service, fair prices, and one of the best techs out in the field, I say give them a call because they made sure we were fully taken care of in an extremely vulnerable situation.

Certain Services deserves 10 stars!!! Bill Certain did a very thorough job of testing our well water and explaining why a whole house reverse osmosis (RO) system was the best way to produce pure drinking water. Other companies just wanted to buy their water treatment systems, even if it left a lot of total dissolved solids in our water. We are so happy with our new RO system, and the honesty, integrity, and professionalism of Bill Certain and his service and office teams! The "Certain Care" monthly service has given us peace of mind and is inexpensive compared with other companies. Certain Services is the BEST!
