How to repair a fence gate

  4. Hold the hinges against the 2x4 gate rail and drill 3/16-inch-diameter pilot holes for lag screws.
  5. Fasten the hinge to the gate rail with lag screws. Repeat to install hinges on the second gate.
  6. Remove the broken picket from the gate and attach a replacement picket using 1 5/8-inch deck screws.
  7. Stand the gate in the fence opening and on top of a 2x4; slip a wedge underneath the gate to raise it to the proper height.
  8. Leave a ½-inch space between the gate and fence post.
