A leaning fence post is the most common fence repair there is — and one of the most over-fixed. Homeowners assume a lean means a new fence; usually it means one post lost its footing. Here's how the pros bring a post back to plumb.
First, diagnose why it's leaning
Three causes dominate: the concrete footing heaved or cracked, the post rotted at grade, or it was never set deep enough. Push on the post and dig a few inches down at its base. Rot at the soil line means the post itself needs replacing; a sound post that moved means the footing failed.
Method 1: steel post spur (sound post)
If the post is solid but the footing failed, the fastest fix is a steel repair spur or post buddy — a galvanized spike driven beside the post and bolted to it, then concreted. It re-anchors the post without dismantling the panels. Ideal for a single leaning post on an otherwise good fence.
Method 2: re-set the post (failed footing)
For a cleaner permanent fix, detach the panels, dig out the old footing, plumb the post, and pour fresh concrete at 30+ inches deep. More labor than a spur, but it restores the post to original strength.
Method 3: replace the post (rotted)
- Rotted at grade? The post must come out — a spur on a rotting post just delays failure.
- Pull the panels, remove post and footing, set a new post in concrete.
- Switch to a rot-resistant species or add a post cap to extend the next one's life.
