Unilock Fence Installation: The Austin Owner’s Guide
Unilock fence installation in Austin typically runs $3,500 to $9,000 for a full perimeter, depending on linear footage, product line, and whether you’re replacing an existing fence or starting fresh. We stock Unilock-compatible components and can usually have a crew on-site within three to five business days. Most Austinn homeowners discover they need us when a post shifts after a hard rain, a gate starts dragging, or a section of wall develops a lean that wasn’t there in March.
What surprises people is that Unilock isn’t a fence brand in the traditional sense. It’s a hardscape manufacturer. Their fence and wall systems are built from interlocking concrete units installed on a gravel and sand base. The “part” that fails is almost never the block itself. It’s the foundation underneath it, the adhesive between courses, or the post-and-panel hardware on hybrid designs. We’ll get into that below.
We’re an independent installation and repair provider, not affiliated with Unilock directly. What that means for you is we’ll recommend the right product for your yard without a brand sales quota behind the advice.
Which Unilock Models This Applies To
Unilock’s fence and wall systems fall into a few families you’ll see around Austin neighborhoods. The Estate Wall line is a modular post-and-panel system that combines precast concrete posts with wall panels. The Pisa and Romanstack lines are segmental retaining-wall blocks that work double duty as low fence or garden walls. If you have a taller perimeter, you’re likely working with Estate Wall or a Unilock column-and-panel configuration where caps and posts mate with wood or metal infill.
Identifying what you have means getting eyes on a few things. Pull one cap stone off a post, if you can, and look for a stamped name on the underside. Measure the post width: most Unilock posts are 16 inches square, built from stackable units. If you have the original invoice, even better. Take a clear photo of the block face and one of the post-cap profile. We can usually match it from photos alone.
On OEM versus aftermarket: Unilock color blends are proprietary. A generic big-box block will not match a Unilock color already in your yard, even if it’s the same nominal size. For repairs, we source OEM or direct-equivalent Unilock units. For full installations, we quote the exact product line you choose so there’s no color-matching gamble. The big compatibility gotcha in Austin: Unilock discontinued a handful of Estate Wall colors around 2019. If you have a discontinued color, matching one replacement panel may mean either a custom tint or accepting a slight variation. We’ll tell you which one is realistic before you spend a dollar.
Styles & brands we work with
Signs Your Unilock Fence Installation Is Failing
- Post lean or tilt. This is almost always a base failure. Austin’s expansive clay soil swells in spring rains and contracts in August heat. If the gravel base wasn’t deep enough, or if drainage shifted, the post moves with the ground. The fix is re-excavation and resetting, not just pushing the post back.
- Cap stones loosening or sliding. The adhesive bond between the cap and the post courses breaks down after years of UV exposure and thermal cycling. You’ll hear a hollow click when you tap the cap. Water then gets into the post cavity, which accelerates every other problem.
- Gate dragging or striking the latch plate. The post holding the gate has settled. You can adjust hinges once or twice, but eventually the settlement wins. That post needs to be pulled and reset on a compacted base.
- Horizontal cracking across a panel or column. In freeze-thaw climates this is water damage. In Austin it’s more likely thermal movement or a vehicle bump. Either way it’s structural, not cosmetic, and the cracked units need replacing before the wall above loses support.
- Gaps opening between courses. If you can slide a putty knife between stacked units, the adhesive has failed or the wall is moving. Gaps let water in and invite the whole section to shift. We see this most on west-facing walls that take the full Austin afternoon sun.

AfterReplacement Cost & What’s Included
Full Unilock fence installation in Austin runs $3,500 to $9,000. The range comes down to three things: linear footage, the product line you choose, and what’s underneath the topsoil. A 50-foot section of Pisa wall costs on the lower end. A 150-foot Estate Wall perimeter with a gate and two columns lands on the higher end. If we’re pulling an old fence and hauling off the debris, that’s line-itemed separately so you see exactly where the money goes.
Every quote we write includes excavation and base prep, gravel and sand, the block and adhesive, install labor, and cleanup. You get a written price before any work starts, and that number is the number on the final invoice. No “the soil was worse than expected” change orders. We pull utility locates before digging, which costs you nothing but protects you from a very expensive afternoon.
All of our work carries the 365-Day Done Right Promise. If a post shifts or a cap loosens inside the guarantee period, we come back and fix it at no charge, covered in writing. And if a repair fails, the return visit to make it right is free. No service call, no re-inspection fee. That’s the Kingswell standard we’ve operated under since 2004.
DIY or Call Us?
You can absolutely do the detective work. Look for the stamp on the block. Take photos. Check if gaps are opening between courses. That tells us what we’re dealing with before we arrive.
What we don’t recommend is resetting a post or rebuilding a wall section yourself. The work means digging a true footer in Austin clay, compacting in lifts, and getting the base dead level before the first block goes down. Get the base wrong and the wall will look perfect for six months, then start moving. It’s also heavy work. A single Unilock post can weigh over 100 pounds. We’ve seen homeowners wrench a back or crush a finger moving blocks without the right equipment.

FAQs
A properly installed Unilock wall or fence system should last 25 to 40 years in Austin’s climate, with the primary wear items being the adhesive joints and the cap stones, not the block itself. The biggest threat to lifespan is base preparation. Our installations include a compacted gravel footer sized for Austin’s expansive soils, which is the difference between a wall that settles in year three and one that stays true for decades. Call (325) 225-5429 for an assessment of your current fence’s condition.
Most of the time, yes. A leaning post can be reset, caps can be re-adhered, and cracked units can be swapped without rebuilding the entire wall. Replacement is usually the answer only when the base has failed across a long run or the product line has been discontinued and matching units are unavailable. We’ll tell you which path makes sense before quoting anything.
Most Austin installs take 2 to 5 working days, depending on linear footage and whether we’re demolishing an old fence first. A single post reset is usually a one-day job. You’ll get a defined arrival window in writing before we start, and our crew leaves the site cleaner than they found it.
We keep common repair materials in stock: cap adhesive, base gravel, post units in the most-used Austin colors, and gate hardware for Estate Wall systems. Discontinued or specialty colors have a 1 to 2 week order window. For kitchen and bath work, we also source KraftMaid, Cambria, and Silestone, but for hardscape we work directly with Unilock’s distribution network. Call (325) 225-5429 and we’ll tell you what’s available this week.
