Very friendly and helpful until it's time for warranty work. Spent a lot of money placing a French drain throughout our basement. Detected a leak while replacing carpet, a leak that was CLEARLY within the area in which the leak was detected. Pictures send to him proved that. Chris asked us to rip the wall apart (no thanks Chris, we did that when you were here originally) to see source of leak which was obviously from the outside...no nearby plumbing or spillages and has yet to fulfill his warranty obligations. I haven't heard back from him in over a month so I doubt that he will. In short, poor workmanship and lack of business honour. STAY AWAY.
