How to fix a leaning fence
It's almost always the post — here's how to diagnose and fix it.
By The T.A.P. Team · October 2024 · 6 min read
A leaning fence almost always comes down to one thing: a failed post. In Texas, posts rot at the ground line, get shoved by wind, or heave and tilt as our clay soil swells and shrinks. The fix depends on the post's condition — a still-solid post can sometimes be re-braced or reset, while a rotted or broken one needs replacing. Here's how to tell which you've got and set the fence straight.
- 1Push the leaning section — which post moves?
- 2Check the post at ground line for rot (probe it).
- 3Solid but tilted? It may have heaved — reset it.
- 4Rotted or broken? The post needs replacing.
- 5Whole runs leaning after a storm? Likely multiple posts.
It's the post, not the pickets
When a fence leans, the pickets and rails are usually fine — it's the post that's given way. Push gently on the leaning section and watch which post moves at its base. Then check that post at the ground line: press a screwdriver into it. If it sinks into soft, punky wood, the post has rotted; if it's solid but tilted, the soil moved it.
Rotted post: replace it
A post rotted at the base has lost its footing and can't be saved. The fix is to remove it (and its old concrete), dig a proper hole, and set a new pressure-treated or cedar post in fresh concrete, then re-attach the rails and pickets. Getting the depth and concrete right — and crowning the concrete so water sheds away — is what keeps the new post from rotting early.
Heaved or loose post: reset or brace
If the post is still sound but leaning because the clay soil heaved or the concrete cracked, you can often reset it — dig around it, plumb it, and re-set it in new concrete. A temporary brace holds it straight while the concrete cures. Sometimes a leaning-but-solid fence just needs the post re-secured and the run re-plumbed.
When to call a pro
One post is a doable DIY project; multiple leaning posts, a long run down after a storm, or a fence where the posts and boards are both failing point toward bigger repairs or replacement — see repair vs replacement. Setting posts correctly in our clay soil is also where DIY fixes often fall short. If several posts are going, it's usually the age of the whole fence showing.
| Symptom | Likely cause | What to do |
|---|---|---|
| One post tilts, wood soft | Rotted post | Replace the post + concrete |
| Post solid but leaning | Soil heave / cracked concrete | Reset the post plumb |
| Post wobbles in ground | Failed/cracked footing | Re-set in new concrete |
| Run leans after a storm | Wind + weak posts | Reset/replace affected posts |
| Many posts leaning | Fence aging out | Consider replacement |
You can DIY
- Identify the failed post
- Probe the post for rot
- Reset a solid heaved post
- Replace a single rotted post
- Brace it while concrete cures
Call a pro
- Multiple failed posts
- A long run down after a storm
- Posts and boards both failing
- Setting posts right in clay soil
- Full fence replacement
A leaning fence is only truly fixed when the post is set correctly — proper hole depth, fresh concrete crowned to shed water, and the post plumb and braced while it cures. Quick fixes like shoving dirt around a wobbling post or bracing without addressing rot just delay the next lean. In our heaving clay soil, a properly set post is the whole game.
Wind, clay, and leaning fences in DFW
North Texas storms bring strong winds, and our expansive clay soil heaves posts as it swells and dries — a combination that leans fences across Plano, Frisco, and Allen every year. We reset and replace posts and rebuild storm-damaged runs. See our fence team.
The short version
- A leaning fence is almost always a failed post, not bad pickets.
- Push the section and probe the post at the ground line to diagnose it.
- A post rotted at the base needs replacing, concrete and all.
- A solid but heaved post can often be reset plumb in fresh concrete.
- Set posts with proper depth and crowned concrete so they don't lean again.
- Multiple leaning posts usually mean the whole fence is aging out.
