Repairing Fence Rails

Fence rails are most likely to
decay where they join the posts.
Inspect them annually.

Rot is a fence's worst enemy and typically attacks bottom-rail joints first. If you catch decay early, you can saturate the damaged spot with a preservative, then mend it as shown below. If the rail has broken away, you'll have to replace it. Use treated lumber for your repairs.

To minimize rot around fences, make sure posts are set in concrete and cut back surrounding vegetation. Plants often keep areas moist and thereby contribute to the effects of moisture on wood.
