If your doors are constructed like mine and they may be as the industry uses similar parts, the framing is metal and wood. The vertical piece at the latch is steel, the rest is wood. My doors have required rebuilding, not a hard job, and need it again. My windows are held in place by little tabs on the plastic frame that supports them. The tabs break off after years and the window slides down in the frame and water gets in and rots the wood. I'm going to do it right this time. I just need someone to help with removal and reinstall of the doors. Good luck.
