Unilock Fence Installation: The Las Vegas Owner’s Guide
Unilock fence installation in Las Vegas typically runs $3,500-$9,000 for a complete vinyl system, and most of our crews can start within 48 hours of your call. We stock Unilock-compatible posts, rails, and panel systems for same-week installation across the valley, from Summerlin to Henderson. Most homeowners realize their fence needs attention when panels start bowing in the Mojave heat, gates sag after monsoon winds, or the whole line leans because the original installer skipped the gravel base.
Which Unilock Models This Applies To
Unilock’s fencing line centers on their vinyl systems, not the paver products they’re better known for. The key is matching your existing post profile: Unilock vinyl fences use a 5-inch square post with a specific wall thickness and routed rail pocket spacing that differs from Veranda, Bufftech, or other brands sold at big-box stores. If your fence was installed between 2010 and 2019, check for a small embossed “U” on the post cap underside or a date stamp on the inside face of the bottom rail.
We carry both OEM Unilock replacement sections and commercial-grade equivalents from our supplier network. The aftermarket rails we use match the 1.5-inch by 5.5-inch Unilock rail profile exactly, but with a higher titanium dioxide load for UV resistance, something that matters enormously in Las Vegas where summer surface temperatures on vinyl hit 165°F. If your posts are still plumb and the concrete footing is sound, we can often replace just the failing rails and pickets without tearing out the whole line.
Signs Your Unilock Fence Installation Is Failing
- Panels bowing outward between posts. The Mojave sun degrades vinyl’s impact modifiers over 8-12 years, especially on south-facing runs. Once the material loses flexibility, thermal expansion has nowhere to go and the panel buckles.
- Gate sagging or latch misalignment. Unilock gates rely on a steel-reinforced top rail that can corrode internally if water gets past the end caps. In Las Vegas, this usually happens when sprinklers hit the fence daily, not from rain.
- Post caps cracking or disappearing. The snap-fit Unilock caps become brittle after years of UV exposure. A missing cap lets water into the hollow post, and in winter freeze-thaw cycles, that water expands and splits the post from the inside out.
- Bottom rail pulling out of the post pocket. This happens when the installer used too few brackets or when the ground shifts. In Las Vegas, caliche soil and poor drainage after heavy rains put lateral stress on fence lines that weren’t properly anchored.
- Whole section leaning after wind events. Unilock vinyl is lightweight, which is great for handling, but it needs deeper post holes and more concrete than wood. A 30-inch depth in sandy soil isn’t enough; we go 36 inches minimum and use a gravel drainage bed.
Replacement Cost & What’s Included
| Scope | Price Range |
|---|---|
| Single panel replacement (rails + pickets) | $350-$800 |
| Gate rebuild with steel reinforcement | $600-$1,400 |
| Partial section (3-4 panels + 2 posts) | $1,800-$3,500 |
| Full Unilock vinyl fence replacement | $3,500-$9,000 |
The spread depends on linear footage, access, and whether we’re working around existing landscaping or hardscape. Our quotes include demolition and haul-away of the old material, new Unilock-compatible components, concrete footings, and hardware. We don’t charge separately for permits if your HOA or the city of Las Vegas requires them. Every fence installation is covered by our 730-Day Done Right Promise, and we put that in writing on every contract.
DIY or Call Us?
You can safely check a few things yourself. Verify your post spacing with a tape measure, standard Unilock sections run 96 inches on-center. Look for the model identifiers we mentioned. Tighten any loose brackets with a socket set. But when it comes to resetting posts in concrete or replacing structural rails, the tolerances matter. A post even half an inch out of plumb compounds across a run and leaves you with a gate that won’t close properly six months later.
We’ve also seen homeowners crack vinyl components trying to force them into temperature-contracted rails in January, or install pickets upside-down so the drainage holes face up, trapping water. The ground doesn’t lie, and neither do we: if the footing work is involved, it’s worth having our crew handle it. Call (855) 951-4361 and we’ll give you a straight assessment of what’s DIY-friendly versus what needs the post-hole digger and laser level.
FAQs
In the Las Vegas climate, a properly installed Unilock vinyl fence lasts 15-25 years, with south-facing panels aging faster due to UV exposure. The key variable is whether the original installer used UV-stabilized material and set posts below the frost line with proper drainage. Call (855) 951-4361 for a free inspection if you’re unsure about your fence’s condition.
Most Unilock fences can be partially repaired if the posts and footings are still sound. We replace individual panels, gates, and rail sections regularly. Full replacement only makes sense when multiple posts are leaning, the UV damage is widespread, or you want to change the fence height or style. We’ll tell you honestly which path saves money long-term.
A typical residential replacement of 100-150 linear feet takes our crew one to two days, including demolition, footing work, and cleanup. Smaller repairs or single-panel swaps often finish in a half-day. We schedule start dates within a week of your approved estimate in most Las Vegas neighborhoods.
We stock Unilock-compatible posts, rails, pickets, and hardware in our Las Vegas warehouse, and our trucks carry the common repair components for same-day service calls. For color-matched replacements on older installations, we may need 24-48 hours to pull from our supplier. Call (855) 951-4361 with your fence details and we’ll confirm availability.
