We were asked to replace an old garage window with a new 32″ Mastercraft steel door w. window.  This is a bit more difficult than a regular door replacement, considering that we have to do a major modification to the opening.  This includes not only opening up the area below the old window, but also filling in the area above the new doorway (since standard doors are 80″ high, and the top of the window was about 88″ high.  In this case, we recycled old vinyl siding from below the window, and pieced it in above the door to make an almost spot-on match.  Looks great, and now this customer can have easy access to his back yard and the location of his future deck/patio!
