Unilock Fence Installation: The Austin Owner’s Guide
Unilock fence installation in Austin typically runs $3,500 to $9,000 for a complete perimeter fence using Unilock’s modular concrete post-and-panel system, with most residential jobs landing between $4,500 and $6,500. We stock Unilock-compatible posts, panels, and caps on our trucks, and most installations finish in two to three days once materials arrive. You usually know you need this page because a post has cracked at the base, a panel has shifted out of alignment, or the freeze-thaw cycles in Austin’s clay soil finally did what they always do: heaved everything just enough to break the mortar joint.
Which Unilock Models This Applies To
Unilock’s fence line spans two main systems here in Texas: the Estate Wall and the U-Cara Multi-Face. Estate Wall uses modular concrete blocks with a textured face and a structural post cavity, while U-Cara lets you swap face panels for different finishes without rebuilding the core. The part that matters is the post. Unilock posts come in 6-inch and 8-inch cavities, and matching the wrong cap or panel to the wrong cavity is the most common ordering mistake we see from homeowners who tried to source parts themselves. If you’re not sure which series you have, flip a cap off and look for the Unilock name cast into the concrete, then measure the post width across the top. Sawyer Remodel Austin is an independent service provider, not affiliated with Unilock, but we install their systems regularly and know which parts cross-fit between series. For most Austin homes, OEM Unilock parts make sense when the visible face matters; aftermarket caps and gravel fill are fine for the parts nobody sees.

Signs Your Unilock Fence Installation Is Failing
- Leaning posts with cracked mortar joints. Austin’s expansive clay soil expands when wet and contracts in drought. That repeated movement transfers stress straight to the post base, and the mortar is usually the first thing to let go.
- Cap stones sliding or falling off. Unilock caps sit on construction adhesive, and 100-degree Austin summers bake that adhesive until it turns brittle. If caps move with hand pressure, they’re on borrowed time.
- Panels shifting out of alignment. When a post settles, every panel attached to it shifts. Gaps open at the top corners first.
- Cracks running vertically through the post core. This is freeze-thaw plus soil pressure. Central Texas doesn’t get deep freezes often, but the ice we do get pops porous concrete that’s already under stress.
- Water pooling at the fence base after rain. Poor drainage erodes the gravel base over time, which causes exactly the kind of uneven settling that kills fence posts in five years instead of twenty.

AfterReplacement Cost & What’s Included
A full Unilock fence installation in Austin runs $3,500 to $9,000, with the final number driven by linear footage, post spacing, whether you’re replacing an existing fence or starting fresh, and site access. A 50-foot run with standard posts and panels usually lands around $4,000 to $5,500. A 100-foot run with tighter post spacing, corner posts, and caps can hit $7,000 to $9,000. Every quote includes removal of the old fence if needed, gravel base, post installation, panel fit, caps, and cleanup. You get a written price before any work starts per The Relay Standard, and the 365-Day Done Right Promise covers the installation for a full year after close. If a post shifts or a cap fails in that window, we come back and fix it.
DIY or Call Us?
You can safely check a few things yourself: inspect cap stones for loose adhesive, note any visible post lean, and look for pooling water along the base. What you shouldn’t do is dig out and reset a concrete post without calling someone who knows what’s underground. Austin lots hide irrigation lines, low-voltage landscape wiring, and in some older neighborhoods, unmarked gas lines that run closer to fence lines than anyone expects. A post digger through a gas line is a bad afternoon that gets worse. For a straightforward single-cap replacement, a competent homeowner with construction adhesive can manage it. For anything involving post extraction, trenching, or re-leveling a run, call us at (409) 834-4854 and we’ll put a written estimate in your hands.
FAQs
A properly installed Unilock fence on a good gravel base lasts 20 to 30 years in Central Texas, but the caps and mortar joints often need attention at the 7 to 10 year mark due to UV and soil movement. The concrete itself rarely fails; the connections and adhesive do. Call (409) 834-4854 for a free assessment if your fence is showing its age.
Single posts and panels can absolutely be repaired without tearing the whole fence out, as long as the adjacent sections haven’t shifted beyond recovery. If the post core is cracked through, we replace that post; if the panel faces are intact, we reset and re-mortar. Call (409) 834-4854 and we’ll tell you honestly whether you’re looking at a repair or a replacement before you spend a dime.
Most Austin residential Unilock fence installations take two to three days from post dig to cap placement, assuming materials are on hand and the site is accessible. Larger runs or fence lines with heavy tree root interference can add a day. We’ll give you a schedule in writing with your estimate.
We stock standard Unilock-compatible posts, panels, and caps on our trucks for the most common Austin configurations, and we order specialty finishes and series-specific faces as needed. If you know your series and measurements, call (409) 834-4854 and we’ll confirm same-week availability before you agree to anything.
If you’ve got a leaning post, cracked panels, or caps that don’t stay put, call Sawyer Remodel Austin at (409) 834-4854 for a free estimate. We’ll measure, assess, and give you a written price before any work begins. Measure twice, cut once, then we actually build the thing.
