DIY Fence Post Fix

Updated March 23, 2017

Replacing a broken fence post can be costly and time-consuming. It involves taking apart the fence, digging out the broken post, replacing it with a new post and reattaching the fence. There is, however, an alternative for fixing a fence post that has broken at or near ground level.

Expose the ground around the fence post base. Remove any grass or debris from the base of the post. Provide a good 18 inches of work area around the post.

Set one side of the fence mender tight against the broken post at ground level at an angle. Use the sledge hammer to force the fence mender below ground. A wooden post will compress as the fence mender slides into the soil or concrete below ground level. When the fence mender is surrounding the break, knock it vertically into place. Set the other side of the fence mender in place and hammer it into the ground using the same method as the first side.

Test the post for tightness. If the area of the post needing repaire is stabilised by the fence mender, hammer the nails into the pre-drilled holes to hold the fence mender in place.

Reinforce the post and fence mender with concrete, if desired. Posts that were initially installed in concrete below ground level can benefit by exposing the top of the concrete and filling the exposed area with additional concrete to provide support to the fence mender and post. Posts that were initially installed without concrete can be dug down to the bottom of the post and backfilled with concrete.


Use gloves, eye and ear protection.
