"Joe W. was very knowledgeable, prompt, professional and honest. I got the distinct impression that he was not trying to up-sell us into something we didn't need just to make some extra money. Workmanship appears to be top-notch and the improvement in our water quality was immediate and very noticeable. Customer service after the install was outstanding as well - I called with some follow up questions a week later and he called me right back in less than 10 minutes (couldn't answer right when I called because he was in the middle of another install job). I would trust him to do work inside my house as he seems extremely honest and reputable. Price is good and being able to support a small, local, family-owned business is huge bonus for us too. Look no further - this is your guy for water quality issues and fantastic service."

"Overestimated the time to complete an 9 hr job by scheduling a 16 hr window (2 guys x 8 hrs) and charged for 16 hrs regardless. I'd imagine they did the same for the materials, 60 feet of duct needed but they quoted 200. Got the job done, but probably twice the price of what it should have been."
