Our floors are red oak. We are starting a remodel this week and just happed to
have some of the baseboard pulled up. The picture
( https://www.flickr.com/photos/77280442@N.../51795827107/in/dateposted/ ) shows
that the drywall does not extend to the floor and the flooring stops a full inch
from the stud wall. It would, of course, be the same at the other wall. This
space is 37 feet long and the two inches of gap have been sufficient. Where the
flooring runs long grain towards the wall, where movement is nil, the drywall
goes all the way down to the subfloor. I believe the cabinets were installed on
top of the hardwood but will not confirm that till later in the week when demo
begins. My two cents is that I would install the floor first, that way yo can
hide a good gap under cabinets. Then just lay door-skin on top stuck down w/
carpet tape while you work in the room. My contractor says he will cover the
floors with heavy paper to protect them, but they are also planned to be sanded
and refinished as a last step since new flooring will need to be matched.
