My sliding glass door faces my living room. Around the corner I have a doublewide window which faces my dining room. I would like to replace my sliding glass door with a window and my window with french doors. Both face the same patio and both are about the same height. The windows are about one inch wider than the sliding glass door. How difficult would it be to do this. I have been given an estimate of $1000 in just labor. I really don't want to spend that kind of money for this if I can do it myself. I would install the french doors first of course. I can remove the wiring and the bottom of the wall under the window and the window with little difficulty. I am a little confused when I get to the framing and the finishing.
