Pocket doors are a wonderful feature for your home, but with time, they begin to show gaps when closed, and the hardware start to drag, causing difficulty. To fix your pocket sliding door, start by removing the door and trimming it. Next, make an opening on the wall to access, remove, and replace the old track with a new one. Replace the hardware on the door panel and adjust the new hardware. Replace the trim and stops, repair the wall, and replace the pocket door pull. Finally, create an opening for the latch, then chisel the mortise for the faceplate.
