Just bought a newly constructed house. Interior master bath door fits at bottom of frame but sticks out of frame about 1/2 inch at top. Bathroom floor also slopes, but other doors in bath fit. Front door also sticks out about 1/2 inch at top. Builder says there is nothing she can do about doors or sloping floor. Is this true? Is there nothing that can be done to fix this? Seems like the doors would not be unrepairable...even if the floor was.
