“From day 1 of contact with your company, ALL of the employees have responded very quickly, and efficiently. Due to the construction schedule, Krieger recommended using a slip-in frame to avoid added schedule delays which was submitted to the contractor and approved as a substitute! I had to order a temp door from another supplier for one of the openings, and your staff quickly answered questions I had, regarding design and hardware locations, in order to match the temp door with the already installed Krieger frame.”
