Leaning fence posts: rot, frost heave, and what actually fixes them
By Jeff Rabkin, JustFix Wood · Published September 24, 2026
A leaning fence is usually one or two bad posts, not a bad fence. The panels and pickets are often fine.
Why posts fail at the ground
The few inches right at the soil line stay wet and have air, which is exactly what rot needs. Posts often look fine above ground and are soft just below it. Push on the post and dig back an inch or two of soil to check.
Our winters add frost. Wet soil freezes and expands, and it can push posts upward or sideways over several seasons, especially when a post isn't set deep enough.
Repair options
- Replace just the failed posts and reattach the existing sections.
- Reset posts deeper so frost has less grip on them.
- Rehang sagging gates with better hinges and add support where they drag.
- Replace broken pickets or rails individually.
When to just replace
If most posts are soft and the panels are falling apart, a new fence may make more sense. If it's a few posts, a repair usually gets you many more years. Send photos of the lean and the base of the posts.
