Unilock Fence Installation: The Houston Owner’s Guide
Unilock fence installation in Houston typically runs $3,500 to $9,000 installed, depending on fence length, Unilock product line, and whether you’re replacing a failed section or installing a full perimeter. Most Houston homeowners discover they need this work when a gate post leans visibly, a panel shifts out of alignment after heavy rain, or the fence starts separating at the base where the Unilock blocks meet the ground. We stock Unilock-compatible fence posts, panel supports, and base anchors on our trucks, so most replacement work can be quoted and scheduled quickly once we see the existing layout.
What we see most often in this market: clay-rich Houston soil expands and contracts through wet-dry cycles, and that movement is harder on fence post footings than almost anything else. The Unilock product itself is well made. The installation details around it are where fences fail first.
Which Unilock Models This Applies To
Unilock makes several fence and screen wall systems, and the installation method changes depending on which one you have. The Brussels Dimensional Stone system and the U-Cara multi-face wall panels are the two we see most in Houston residential fencing. Brussels Dimensional uses individual stone units stacked dry or with minimal adhesive, often called a dry-stack look. U-Cara is a panelized system that mounts to a reinforced concrete or steel frame, then the stone faces clip or fasten onto the panel structure.
Here’s a compatibility gotcha that catches people: U-Cara panels are not interchangeable with Brussels Dimensional stone units, even when both carry the Unilock name and look similar from ten feet away. The mounting systems are completely different. If a U-Cara panel face breaks and a homeowner tries to replace it with a Brussels stone from a local yard, the dimensions will not line up and the weight load on the panel clips is wrong. You match the system to the system. Check the back of any broken unit for a molded-in name or code, or look for a small Unilock stamp on the face. If there is no marking, take a photo of the broken unit next to a tape measure and send it to us before buying anything.
Elmstead Remodeling Houston is an independent service provider, not affiliated with Unilock. We install Unilock-compatible fence systems and source genuine Unilock units and OEM-matched components wherever available. For some discontinued Unilock lines, the original units are no longer manufactured, and we have to match with a quality aftermarket equivalent that replicates the face dimension and color range as closely as the current market allows. We will tell you which path applies to your fence before any money changes hands.

Signs Your Unilock Fence Installation Is Failing
- Leaning gate post or end post. This usually means the footing was sized for a different soil condition than what exists in your yard. Houston’s gumbo clay holds water during wet months, then shrinks hard in July and August. A footing that was marginal from day one will fail within a few years as the soil works against it.
- Gap opening at the base of the fence. When you can see daylight under a section that used to meet the ground, the ground has settled or the base course was not set on compacted material. In Houston, this often appears first on the side of the yard that drains toward the street or the bayou.
- Panel faces cracked or spalling. Spalling on concrete stone faces is a moisture problem. Water gets into the surface pores, the Houston freeze-thaw cycle does its work, and small chips become visible cracks. A hairline crack that runs through multiple units usually points to structural movement beneath, not a material defect.
- Fence section separating at a vertical seam. Unilock walls and fences shift when the substrate was not leveled or when drainage behind the wall is pushing against it. Houston’s heavy spring and summer rains saturate soil quickly, and if there is no weep or drainage path behind the fence, the water pressure does the pushing.
- Fence sounds loose when you knock on it or push it by hand. Loose caps or stones can sometimes be reset with fresh adhesive. But if the whole section moves as one piece, the connection between the fence face and its supporting frame or footing has failed, and that needs structural work, not cosmetic repair.
Key Takeaways
- Unilock fence installation in Houston runs $3,500 to $9,000 installed for most residential fence projects.
- The failure pattern we see most often is soil movement in clay-heavy Houston yards, not product defects.
- U-Cara and Brussels Dimensional systems are not cross-compatible. Match the system, not the look.
- A written price before we start and a photo of the cleanup before we leave is standard on every Unilock fence installation we do.

AfterReplacement Cost & What’s Included
For a typical Houston residential fence, Unilock fence installation runs $3,500 to $9,000 installed. The lower end covers shorter runs, replacing a failed section, or resetting existing posts with new footings. The upper end covers full perimeter fences, taller screen walls, gate integration, or U-Cara panelized systems where a reinforced concrete or steel frame must be built before the stone faces go on.
What drives the range more than anything is the condition of what is under the fence. If the original footings were undersized or the base was built on uncompacted fill, the labor cost goes up because we are rebuilding the foundation, not just swapping the visible part. The second factor is the current Unilock product line. Genuine current-production Unilock units are ordered at market price. Discontinued lines cost more to source or require an aftermarket match.
Every quote includes the written price before work starts, genuine or OEM-matched Unilock components, new footings and base material where needed, site protection with drop cloths and shoe covers, a photo of the clean-up before the crew leaves, and the 365-Day Done Right Promise. If it is not done right, we make it right. That promise is printed on every project, not offered as an upgrade.
We also stock parts for KraftMaid, Cambria, and Silestone systems, so if your fence project is part of a larger outdoor or kitchen effort, we can often coordinate the material sourcing in one pass.
DIY or Call Us?
There are three things a Houston homeowner can safely check without a pro. First, look at whether water is pooling at the fence base after a normal rain. Pooled water is a drainage issue you can document and flag. Second, check for visible cracks in the face units and note where they start and stop. Third, walk the fence line and mark every spot where the gap between ground and fence changes by more than half an inch. That information helps us quote faster.
What we do not recommend is digging out a leaning Unilock post on your own. A post set in Houston clay with a concrete footing is under load, and when the footing is compromised, the post can shift suddenly while you are working beside it. A falling fence section weighs more than most people expect, and the risk to hands and feet is real. We see this specific scenario every spring. If a section is leaning or moving, call us at (254) 272-5240 and we will come look at it. The estimate is free.
FAQs
A properly installed Unilock fence should last 25 years or more in Houston, with the caveat that the footing and drainage details matter more than the stone itself. The stone can easily last decades. Poor footings in clay soil are what shorten the lifespan to 10 or 15 years. For an exact assessment of your existing fence, call (254) 272-5240 and we will come out at no charge.
Yes, in most cases a failing fence section can be repaired by resetting the posts, rebuilding the base, and matching the existing Unilock units. Full replacement only makes sense when the damage is widespread, the original product line is discontinued beyond aftermarket matching, or the supporting structure has failed. Call (254) 272-5240 with photos of the damage and we will tell you which path fits.
Most Unilock fence installations in Houston take two to five working days from the day the crew starts. Footing work, curing time, and matching any existing Unilock units add days. We will give you a written start-to-finish schedule in the quote, and if that schedule changes, you hear it from us before it happens.
We stock common Unilock-compatible fence posts, panel supports, base anchors, and OEM-matched components on our trucks for the fence types we see most in Houston. Discontinued or custom Unilock colors and sizes may need to be ordered, which typically adds three to seven days. Call (254) 272-5240 and we will confirm what is on the truck today for your specific fence.
