I've heard contractors say to install doors first then flooring, and others suggest the opposite. I'm installing new 3/4" prefinished flooring and new doors/closets (prehung wood/ primed white). What are the advantages/disadvantages to installing the doors after the floors? What sequence would result in the best finish? Thanks
I like to put the flooring in first. If you're working on the last row against a wall with a door in it, and you have to cut a piece that's half strip against the wall for half its length, and a full strip in the doorway, it's easier to get it into place if the jamb isn't in the way. It also means you can get the fit better at the bottom of the door jambs, without needing to use a flush-cut saw to trim the jamb before you can fit a floorboard under it, or ending up with a gap between the jamb and the floorboards.
As far as cons, I guess putting the doors in first means less activity in the room once the floors are in place, and thus less risk for dropping a hammer and marring the floor, or tracking dirt across the finished surface.
