Penn Windows & Doors was very customer-oriented. They were willing to work with us on a time frame for the installation of our door that met our needs. The door sample kit was a great idea that enabled us to see the actual colors, glass thickness and hardware before making our decisions.  I loved the computer sketch that gave us the actual look of the finished door. The installer was very careful with our wooden floors and was excellent in cleaning up. Excellent!  Great job!
