I used Clearwater Systems Hamilton & Missoula, MT a few weeks ago to have my water filtration system installed. My only complaint is that, when they first came out, I was told they would be here at eleven, but they showed up earlier without letting me know, so I wasn't there to talk with them about the installation. Other than that, everything has been great. They are punctual, nice people who did a great job. I would use them again if anything else were to come up.
