The door went up to the laundry room today. We had to raise the opening a few inches to accommodate a standard size door, and discovered there was power going over the door frame as well, but it all worked out fine. Buying one of those pre-hung doors sure helps, too. It actually feels like a real doorway now, instead of a glorified closet with big bi-fold doors.
Pictures below.
(Edit by Cabol: The first photo is from last August when Andy was trying to catch the snake in the basement. We forgot to take a before shot, and this was the best we could find. Alas, it does not quite show the full horridness of what was before.)
