The upper door can be easily removed & rebuilt. I did mine several years ago. The bottom part of the door is a piece of 2 x 10, I think (memory failing me now) and the sides are like 2 x 2's for the framework. The center of the door consists of a piece of styrofoam that the glass window sits in. Will have to drill out the new wood for the door lock assembly. I used treated lumber on the project. If I can do it, anybody can do it. It is not a hard thing to do. My loving wife did provide me with adult supervision.
