Tuning up a balky door for sliding glass door repair: Adjust rollers
To start your sliding glass door adjustment project, first lift or lower the door on the track with a screwdriver or Allen wrench. Raise it just enough to clear the track and roll smoothly. Locate the two adjusting screws at the bottom of the door (on the face or edge of the door) and pry off the trim caps that cover the screws. If one side looks lower, raise it until the door looks even on the track (Photo 1). If the door still sticks, turn both screws a quarter turn to raise the whole door. Then slide the door just short of the jamb and be sure the gap is even.
