I am planning on replacing the entry door from the garage into the house. The old door is split and has no weather stripping (no threshold, the 70's shag I took out sealed the bottom). Beneath the carpet is hardwood that I had refinished. I plan on buying a prehung door and ripping out the old door down to the rough opening. Should I rip out the few hardwood strips in the door opening or should the new door lay on top of it?
Should the new door rest on the floor (hardwood) or the subfloor?
