- 1). Put on all protective gear.
- 2). Remove all interior and exterior trim, using a crowbar and hammer. If your trim is held in place with screws, use a cordless drill and screw bit to remove the trim screws first, then pry the trim off the wall. If you want to use the old trim as a template for the new, then try not to break it upon removal.

- 6). Pull out the french door frame with your helper.

Place the door in the rough opening hole with your helper. Attach 2 stainless steel screws through the door frame into the wall studs. Do this on both sides, just as a temporary way of holding the door up. Level the door as you add more shims and place a stainless steel screw about every 18 inches or so, all the way around the frame. Use the cordless drill and screw bit for attachment. - 12
Open and close the door to make sure it operates smoothly. - 13
