Hello, My contractor is installing my upper cabinets and says they should be flush against the ceiling with no trim between the cabinet and the ceiling. Looks awful to me. The doors go right to the top of the cabinet too so are only about 1/2 inch from the ceiling. Shouldn't there be some sort of trim up there to finish the upper edge where the cabinet meets the ceiling? If I move the cabinets down to allow more space for trim, then there's no place on the cabinet frame to nail in the trim. It would have to be nailed to the ceiling only. Thanks for any help.
