Rated 4 out of 5 by from Answered questions, and then some... KC Building Supply Co did a fine job answering my questions. I had a contractor (who can no longer be found) install some double hung windows. I now have a tilt latch issue with one of them. They were very helpful in (a) getting me to the right person and (b) once talking to the right person, all my questions were answered, and they gave me more information that was really helpful. Definitely will go back if I need any other matierial.

Rated 1 out of 5 by from Run away as fast as you can. I've had multiple issues and heard more stories from other contractors. Unless you need the absolute lowest cost and worst service stay away. If you are a major builder and spend a ton of money they might give a hoot about you and your business. I've heard stories of people threatening to sue them and their response was go ahead. Not a single concern for the end user.
