I'll get whole flooring and all interior doors replaced for the main level
of my house. Laminate to replace carpet, do it myself. For doors, get a
carpenter to install pre-hungs. Doors include 4-fold doors for a couple of
closets.

I think the best sequence is:
1) remove existing doors/frames.
2) lay laminate flooring
3) install doors on new flooring.

Advise please. Thanks.

John
