Terrible! They sent someone out to look at my system and it was clear that he was not knowledgeable. He made several reccomendations that I knew were bad, even, with my limited knowledge, He took no measurements, no notes, and no water samples to determine what treatment system would be needed. They never followed up, so I had to call to request the estimate. They sent me an estimate that didn't match the job. When I asked about it he never returned my call or sent a corrected estimate. DO NOT WASTE YOUR TIME!
