Just bought a newly constructed house. One interior & one exterior door are out of plumb. Both fit door frame at bottom & stick out about an inch from top side of frame. Builder says there is nothing she can do about this. Is this true? Can anyone suggest a fix for this problem? Floor in the bath where the interior door doesn't fit also slopes which the builder also said she wasn't prepared to fix, but we knew this when we bought house. Don't know if this is related to the bath door not fitting. Other doors in the room fit okay.
