the importance of treating hard water in the home

Because every home is different, in order to recommend a system for your hard water problem, we offer a free site evaluation, do some testing, learn about your water use patterns and your preferences. From that we can make some recommendations and make sure you understand them.

If you are at a point where you would prefer to ask some questions by phone or email, we are happy to answer all of them!

From start to finish they exceeded my expectations. My hard earned money was well spent on my new Kinetico system, making our water safer for my family. I am stunned by their attention to detail and fantastic customer service. I would give more stars if I could!

Water treatment may seem like a small piece of the puzzle, but it’s actually critically important to our work. I wouldn’t choose any company other than Secondwind.
Bonnie Lewis, Lake Sunapee Protection Association
THANK YOU!!! for everything. You and Shane were both very professional and excellent at explaining and answering questions. I am really impressed with how simple and self explanatory the system is. The warranty and your customer service are added reassurance. I wish I had found you years ago.

Frequently Asked Question

What is hard water?

Hard water contains dissolved calcium, magnesium and, in many cases, iron. Most homes have hard water, whether it is supplied by a private well or a municipality. In many cases, homeowners don’t realize they have hard water or the constant and expensive harm it causes.

Hard water dries out skin and makes hair brittle. It causes soap scum in tubs and showers and spots on faucets, fixtures and dishes. It also causes scaling in appliances and water heaters, which results in a reduction of efficiency, costly repairs, high operation costs and premature replacement.
