I did doors before carbet i m with ed 1 2 off the floor but i did all the finish trim after carpet set the base and door casings gently on the carpet don t push it tight.

At this point the only other difference with installing a pre hung door for a room that will be carpeted is that i keep the shims and the nails close to the floor on both sides.
I had some woven backed carpet from stanton that i had to install in a couple of rooms the other day and knowing the stuff is stiff and doesn t give much stretch especially in the width i decided to undercut the door casings between the two rooms.
My advise install the trim and doors first and stress to the carpet installers to be as careful as possible.
