J.A's Privacy and Perimeter repairs fence posts across the Denver metro: leaning, rotted, or wind-snapped. One or two bad posts rarely mean a new fence. We pull the failed post, reset it in concrete 36 to 42 inches deep below the Front Range frost line, and leave sound rails and panels alone. Owner Julian Lopez is licensed and insured, with 15+ years on the Front Range, and gives a written quote before anything is dug.
A fence post that leans, wobbles, or snapped off at the ground is almost always the first thing to fail on an otherwise good fence. I'm Julian Lopez, and I've been resetting and replacing fence posts across the Denver metro for 15+ years.
The part the national how-to articles leave out is why posts fail here specifically. Along Capitol Hill and Wash Park the soil is bentonite clay. It swells when it's wet and shrinks when it dries, and that cycle works a shallow-set post loose until it leans. Add the freeze-thaw heave we get on the Front Range, roughly 155 cycles a year, and a post set at two feet in a bag of dry concrete doesn't stand a chance. The other half of our post calls come after an August microburst, when 70 mph wind treats a solid 6-foot panel like a sail and snaps the post at the weakest point.
That's the honest frame for this whole page: a leaning or rotted post is a diagnosis, not a guess. We read why yours failed before we quote a fix, because a post that heaved from a shallow footing and a post that rotted at the concrete collar are two different repairs. This page covers post repair across the whole metro. If your job is inside the city, our <a href="/services/fence-repair-denver-co">Denver residential fence repair</a> page goes deeper on the clay and housing stock, and our broader <a href="/services/fence-repair">Front Range fence repair service</a> covers panels, gates, and whole-run storm damage.

How to Repair a Damaged Fence Post the Right Way
Repairing a damaged fence post means pulling the failed post, clearing the old footing channel, and resetting a sound post in full concrete at 36 to 42 inches, below the Front Range frost line. That depth is the whole job. A post reset shallower than frost depth in Denver clay works its way back out within a season or two, which is why we don't prop, brace, or bolt a leaning post back upright and call it fixed.
<aside class="my-6 rounded-md border border-border bg-card p-4 text-sm">Front Range fact: The Denver metro averages roughly 155 freeze-thaw cycles a year, and the bentonite clay through Wash Park and Capitol Hill heaves shallow-set posts every spring. A post reset at 24 inches here is a repair that calls us back next year. We set to 36 to 42 inches to get under the frost line for good.</aside>
After 15+ years resetting posts across this metro, here's the pattern we've learned the hard way: the cheapest-looking fix, dumping fresh concrete around a wobbly post without pulling it, is the one that fails fastest. The old footing channel is already cracked and oversized from years of clay movement, so the new pour never bonds to undisturbed soil. We pull the post, clean the hole down to solid ground, set a plumb post, and backfill with a gravel-and-concrete sandwich that drains water off the base instead of trapping it against the wood.
What a correct post reset includes
Pulling the failed post rather than patching around it
Clearing the footing channel to undisturbed soil
Digging or drilling 36 to 42 inches to get below frost line
Setting the post plumb and bracing it through cure
A gravel base under a domed concrete crown so water sheds instead of pooling
Reattaching rails and panels after the concrete sets, usually a next-day return
We reset the bad post without touching good rails and panels, so you're not paying to replace a fence that's mostly fine. Not sure whether yours is a reset or a replacement? Call [720-609-6094](tel:+17206096094) and we'll read it on-site before quoting.
How to Fix a Rotted Fence Post Without Replacing the Whole Fence
Here's the honest answer first: if a wood post has rotted through at the concrete collar, you replace that post. There's no coating, bracket, or splice that restores strength to wood that's gone soft at grade. The good news is that fixing it does not mean replacing the fence. We swap the single rotted post and leave the sound posts, rails, and panels in place, so a four-post problem stays a four-post job.
Where rot starts on a wood post
Rot almost always starts at the same place: the line where the post meets the top of the concrete footing. Water collects at that collar, freezes, thaws, and soaks into the end grain until the wood turns punky. You can usually confirm it by pushing a screwdriver into the post an inch above the concrete. If it sinks in, that post is done.
<blockquote class="my-6 border-l-4 border-accent pl-4 italic text-foreground/85">"The posts we see rot first are the ones set in a concrete collar that traps water against the wood. We reset replacements on a gravel base under a domed crown so the water drains off instead of sitting at grade."</blockquote>
When a rotted post can't wait
A single rotted post in the middle of a run is a scheduled repair, not an emergency. But a rotted post on a gate side is different. The gate's weight accelerates the failure, the post racks under load, and the gate stops latching. Those we move up. If your existing post is sound but the wood around the hardware has split, that's usually a hardware and bracing fix rather than a post replacement, and our Front Range fence repair service covers the gate side.
<aside class="my-6 rounded-md border border-border bg-card p-4 text-sm">The honest part: If we scope your fence and find posts rotted at grade across most of the run, we'll tell you a replacement makes more financial sense than resetting post after post. We check post integrity at grade before we quote so a repair job never turns into a surprise replacement halfway through.</aside>

What To Do If Your Fence Post Is Wobbly or Leaning
A wobbly or leaning fence post has one of three causes, and the fix depends on which one it is. The post is loose in its footing from clay movement, the post has heaved up out of the ground over several winters, or the post has snapped or rotted below grade. We diagnose which before we quote, because propping the wrong one back up wastes your money.
Loose in the footing
If the post rocks but the concrete is intact, the clay around the footing has shrunk away from it. We pull and reset. Shimming or re-pouring around a loose footing in bentonite clay buys you a season at most before the movement starts again.
Frost-heaved
If the post is standing proud of the rail line or your gate suddenly won't latch after winter, that's heave. Water froze under a shallow footing and pushed the post up. Once a post has heaved twice, the footing channel is compromised and it will keep heaving until it's reset below frost line.
Snapped or rotted below grade
If the post moves freely at the base or you can see daylight at the ground line, it's failed structurally and needs replacement. This is the most common result of a Front Range microburst, the post snaps at grade where the leverage is highest.
<blockquote class="my-6 border-l-4 border-accent pl-4 italic text-foreground/85">"A leaning post is a diagnosis, not a guess. We read why yours failed before we quote, because a post that heaved and a post that rotted at the collar are two different fixes."</blockquote>
One thing worth saying plainly: a leaning post rarely fixes itself and rarely stays put. The clay cycle and the wind that caused it are still there. Catching it as a single-post reset is far cheaper than waiting until it pulls two neighbors down with it. Tell us what your post is doing at [720-609-6094](tel:+17206096094) and we'll tell you which of the three it is.
Why Denver-Metro Posts Fail: Clay, Freeze-Thaw, and Wind
Fence posts across the Front Range fail for reasons that don't show up in the national spec sheets. Three local conditions do most of the damage, and knowing which one hit your fence is how we size the right repair.
Bentonite clay movement
The expansive clay through Capitol Hill, Wash Park, and western Aurora swells when wet and shrinks when dry. That seasonal push-pull is relentless on a post. A footing that doesn't reach undisturbed soil below the active clay layer gets worked loose a little more every year until the post leans. This is why we set deeper in clay zones, 42 inches where the general metro standard is 36.
Freeze-thaw heave
Denver nights drop below freezing through much of the year, with daytime thaw on many of them. Each cycle lets water under a shallow footing freeze, expand, and lift the post. Set below the frost line, a post rides out all 155-ish cycles. Set above it, the post migrates upward one winter at a time.
Microburst and 70 mph wind
A solid 6-foot privacy panel is a sail. When an August microburst rolls across the metro at 70 mph, the load lands on the posts, and the weakest post snaps at grade. That's why our standard build sets posts on 6-foot centers rated to 70 mph, and why a post-only repair on a wind-damaged fence has to match that spec or it'll just fail again at the next cell.
<aside class="my-6 rounded-md border border-border bg-card p-4 text-sm">Not sure your post is the real problem? If your neighbor's fence is fine and yours keeps heaving, the soil at your specific spot may hold more clay. We read the footing, the soil, and the wind exposure on-site before quoting, so the fix matches the actual cause.</aside>
When Fence Post Repair Is the Wrong Call
We'd rather lose a repair job than sell you one that doesn't make sense. So here's the honest line most contractors won't put in writing.
Don't pay us to reset post after post on a fence that's already done
If your fence is 15-plus years old and we find posts rotted at grade across most of the run, resetting them one at a time is throwing good money after bad. The labor to reset six or eight posts approaches the cost of a new fence, and you'd still have aging rails and panels. At that point a planned replacement is the smarter spend, and our guide to what it costs to replace a fence outright lays out the trade-off.
Don't call us for a single wobbly post you set last year yourself
If a post you installed recently is just loose and the wood and footing are sound, you may be able to re-tamp and re-brace it yourself. We'll tell you that on the phone rather than roll a truck for a job you don't need us for. Where we earn our keep is the diagnosis, the frost-depth reset, and the posts that have actually failed.
Don't replace a post when the real problem is the gate
A gate that drags is sometimes a post problem and sometimes a hinge or brace problem, and those are different, cheaper fixes. We check before we quote. That's the whole point of reading the fence first.

Our Fence Post Repair Process
Here's exactly what happens from your first call to the final walkthrough, so you're not guessing.
First call. You call [720-609-6094](tel:+17206096094). We ask what the post is doing, leaning, wobbling, rotted, or snapped, what the fence is made of, and whether a gate or a safety hazard is involved. Five minutes, usually.
On-site diagnosis. Julian or a core crew member walks the fence, pushes on each post, and checks integrity at grade, not just by eye. This is where we catch the second bad post that looks fine but is soft at the collar.
Written quote. You get an itemized quote before anything is dug. Materials and labor are broken out separately. We don't start without your sign-off.
Reset or replace. We pull the failed post, clear the footing channel to solid ground, dig or drill to 36 to 42 inches, set the new post plumb, and backfill with a gravel-and-concrete sandwich under a domed crown.
Cure and reattach. Concrete needs time. We brace the post and return the next day to reattach rails and panels after it sets, so the connection is made to a post that won't move.
Final walkthrough. You walk the repair with us before we leave. Anything you're not happy with gets handled on the spot.
Every post reset is backed by our 1-year workmanship guarantee. If a post we set shifts within the guarantee period from our work, we come back and fix it at no charge. That covers our workmanship, not a new storm or a post we never touched.
Frequently Asked Questions
How much does a fence post repair cost?
We don't publish a flat rate because a single leaning-post reset and a wind-snapped post that took a rail down with it are not the same job. The cost depends on how many posts failed, whether it's a reset or a full replacement, the material, how deep we have to dig for frost line, and access. Post work is labor-intensive relative to its visible size because it involves digging, concrete, and cure time. The fastest way to an accurate number is an on-site estimate, and we give you a written, itemized quote before any work starts. Call 720-609-6094 to schedule.
Can you fix just one fence post without replacing the whole fence?
Yes, and that's most of what we do. One or two failed posts rarely mean you need a new fence. We isolate the bad post, reset or replace it below frost line, and leave the sound posts, rails, and panels in place. The exception is a fence that's 15-plus years old with posts rotted at grade across most of the run, where resetting them one at a time approaches the cost of a new fence. We check integrity at grade before we quote so you know which situation you're in.
Why does my fence post keep leaning after I reset it?
Almost always shallow depth. The Denver metro averages roughly 155 freeze-thaw cycles a year, and the bentonite clay through Wash Park and Capitol Hill swells and shrinks every season. A post set less than 36 inches deep, or patched with fresh concrete without pulling the old post, works loose again within a season or two. The lasting fix is pulling the post, clearing the footing channel to solid ground, and resetting in full concrete at 36 to 42 inches, below the frost line. Set that way, it stays put.
Can a rotted fence post be repaired without replacing it?
No, not if the wood has rotted through at the concrete collar. There's no coating or bracket that restores strength to wood that's gone soft at grade, so that post gets replaced. But replacing a rotted post does not mean replacing the fence. We swap the single rotted post and leave the rest of the run alone. You can check it yourself by pushing a screwdriver into the post an inch above the concrete, if it sinks in, that post is done.
My fence post snapped in a windstorm. Is that covered by insurance?
Often, yes. Wind is a named peril on most Colorado homeowner's policies, so a post snapped by a Front Range microburst is frequently covered minus your deductible. The claim gets paid on documentation, not on your word, so we prepare an itemized damage report with photos formatted the way Colorado adjusters expect. We've worked with every major homeowner's insurer operating in Colorado. Call 720-609-6094 and we'll photograph the damage the way your adjuster needs it.
How deep should a fence post be set in the Denver metro?
36 to 42 inches, to get below the Front Range frost line. We set to 36 inches as the metro standard and 42 inches in the heavy bentonite clay zones like Capitol Hill and Wash Park, where the soil movement is worst. Anything shallower will heave or lean in this climate. If a contractor quotes a post reset without mentioning frost depth, ask specifically how deep they're going. 'Two feet' is the wrong answer here.
How long does a fence post repair take?
A single post reset usually takes a few hours on-site, but the concrete needs time to cure. We set the post and brace it on day one, then return the next day to reattach rails and panels after the concrete has set, so the connection is made to a post that won't move. Multi-post jobs after a storm can run a full day plus the cure-day return. We give you a realistic timeline when we write the quote.
