Transitions for Laminate Flooring

Q: When installing laminate flooring across rooms, are transitions necessary? For instance, if both a bedroom and the hallway will be the same laminate floor, is a transition at the bedroom doorway required or can the flooring flow smoothly together from bedroom to hallway?
Thanks.
A: The quick answer here is “no.” Transitions are not required when running the same flooring smoothly through multiple rooms. Keep in mind that if you choose not to use transitions you must still leave proper expansion gaps along the entire edge of the floor, which includes door ways. If you do not leave a full expansion gap in the door ways it is very likely that you will encountering bowing around the doors as the floor expands and lifts without a gap to move through.
The easy way to incorporate this gap while maintaining a professional look would be to undercut the door jambs so that the gaps are underneath the jamb and moldings for the walls.
