Unlevel trim piece that will not be repaired.
The bottom trim piece on the inside of my sliding glass patio door was installed unlevel, making the floor look unlevel. I have talked with the sales manager and installation manager for Nashville but no one will address the issue. The number for the Nashville office is always backed up and you are asked to leave a message that is never returned. I was called everyday for about a week and a half to let me know that the door was in and ready to be installed. After installation and final payment, Window Nation is no longer interested in me. I hope the door itself never needs service.
