Review of Ganser Company Inc.

We met with Jason Hawkins he answered all her questions and was very courteous and informative we signed for a Kohler bathroom remodel and are meeting him Monday for a window Sun tunnel and entry door We’ve had a lot of negative experiences with contractors and so far through the experience with Ganser Company think we have found an exception to that rule
