Excellent work on our kitchen remodeling project. I would recommend Bob Nanz and his son Ian, to anyone. Quality work that we really appreciate from the support work out. That is so important. It is rare to be able to find a contractor today who will really work with you on the details. Bob's son Ian understood what we wanted and got it done. Our 15 year old kitchen was gutted and rebuilt from the wallboard out and up. Beautiful results, as for example, the tile work backsplash behind the sink. Positive even rave reviews from everyone who has seen the end result so far. To be continued.
