Leaning Fence Repair in Allen, TX
When a fence leans, the boards are following a post that has rotted through or come loose in the ground. The repair happens at that post.
Why Fences Lean Here
A lean almost always traces to one of two things: a wooden post rotted at the ground line, or a footing that has loosened in Allen’s clay.
Collin County sits on Blackland Prairie clay. The Handbook of Texas describes it as soil that opens deep cracks in dry weather. Every dry summer the ground pulls back from a post footing, and every wet spell it closes up again. Over years that movement works a shallow footing loose.
Rot is the other cause. A wooden post stays damp where it enters the ground, and that is where it gives way. From the yard it looks like a fence that suddenly leaned after a windy night. The wind only finished it.

How the Repair Is Done
Find every bad post
A contractor pushes each post along the leaning stretch and a few beyond it. The lean shows where the worst one is; the ones beside it are often not far behind.
Take the load off
Rails are detached from the failed post and the section is braced so it does not fall.
Old post and footing out
The post and its concrete are dug or pulled out. Setting a new post beside an old footing leaves the new one off the fence line and is a shortcut worth asking about.
New post in
The City of Allen’s fence guideline says all fencing requires metal posts and that posts are placed 18 inches deep in concrete. A galvanized steel post goes in the hole, is held plumb and the concrete is left to set.
Rails back on
Rails are fastened to the steel post with brackets and the section is pulled back into line.

When Straightening Is Not Enough
Bracing a leaning section, or pouring more concrete around a rotted wooden post, stands the fence up for a while. The post is still rotted. If a contractor proposes it, ask how long it is expected to hold and what the same visit would cost with a new steel post.
If more than a few posts in a run are loose, read the repair-or-replace check before agreeing to anything.
Post holes are digging. Texas811 says Texas law requires contacting 811 two business days ahead so utilities can mark their lines. Ask the contractor to confirm the request was made.
Questions About Leaning Fence and Post Repair
How much does it cost to fix a leaning fence?
HomeAdvisor’s Allen page gives an average of $200 to $400 for straightening a leaning fence. A 2026 national guide gives $217 to $960 for leaning fence repair and $160 to $450 to replace a post. A contractor’s quote depends on how many posts are involved.
Can a leaning fence be fixed without replacing posts?
It can be braced, but if the post is rotted or the footing is loose the lean returns. Replacing the post is the lasting repair.
Will the new steel posts show?
On the side where the rails are, yes. Some owners have the posts boxed in with wood. If your homeowner association has an appearance rule, check it first.
My fence leans toward my neighbor. Whose job is it?
That depends on whose fence it is and what the two of you agree. Texas law generally does not force a neighbor to share the cost. See the shared fence page.
