"Overall excellent. My only quibble is that the screen over the window had holes but it was replaced within a week. I would use them again if I need another egress window. Note, these windows are primarily to let people out. If a fireman, or anybody else, have to get in they still have to break the glass."

"Windows are good. Work was sloppy. Still finding shards of glass on the floor and the furniture a week after completion. Caulking looks like a third grader did it- including caulking the screen door to the frame. For this type of investment, they should act like professionals."
