We just remodeled a bathroom that has two pocket doors. New pocket door frames were installed and before installing the drywall and tile over that, the doors were gliding smoothly in and out of the pocket (frame). Now, however, the doors are rubbing on the frame at about the middle of the door. Could the installation of the tile have caused the frame to close in? And if so, is there a solution without tearing out the tile? One side of the pocket door is tile all the way to the ceiling and the other side has tile up to about 40 inches and then regular dry wall above that.
