How to Repair the Track for a Sliding Patio Door


Sliding patio doors get a lot of use, especially during the spring and summer. Over time, the track on your patio door will need repairs. Screws will become loose, and the track will inevitably become bent. You can repair the track yourself and keep your patio door working smoothly all year long. Track repairs do not require a lot of time and seldom involve major construction. Most repairs can be made with simple hand tools and a vacuum cleaner.

Things You'll Need

  • Flat-head screwdriver
  • Vacuum cleaner
  • Tape measure
  • Scrap wood
  • Circular saw
  • Hammer
  • Open the sliding patio door to the full open position. Insert a flat-head screwdriver into the track channel and scrape all of the dirt and debris loose. Pay special attention to the corners and end of the track where the track meets the door jamb.

  • Vacuum all of the dirt and debris from inside the track. Use the corner cleaning attachment on your vacuum cleaner.

  • Tighten the screws in the bottom of the track channel that secure the track to the floor. Remove any screws that will not tighten and install slightly larger screws. Often, loose screws will cause the door not to operate properly.

  • Measure the inside channel of a portion of the track that has no damage with a tape measure. Cut a piece of scrap wood with a circular saw to the measurement.

  • Insert the scrap wood into a portion of track that has no damage. Gently tap the piece of wood down the track with a hammer to bend the track back into shape if the track has been bent inward.

  • Place the wood inside the track where the track has been bent out and gently tap the track with a hammer to bend the track back to its original position. Operate the sliding patio door to test the operation in the track.

Tips & Warnings

  • You can order track toppers to cover track that has corrosion or extensive damage. Track toppers include a thin rail topper and two end clips for the sliding door. Many home improvement stores and door manufacturers now carry track toppers for sliding doors.
