Unilock Fence Installation: The Dallas Owner’s Guide
Unilock fence installation in Dallas typically runs $3,500 – $9,000 installed, depending on linear footage, the Unilock product line you’re working with, and how much base prep your soil needs. We stock Unilock-compatible fence materials locally and can usually start within a week of your written estimate. Most Dallas homeowners call us after a section of their existing fence starts leaning, a post shifts in the gumbo clay, or a previous contractor’s install didn’t survive the first hard freeze-and-thaw cycle.
What you’re dealing with isn’t a generic vinyl fence. Unilock fence systems use interlocking post-and-panel construction that differs from standard box-store vinyl fencing in wall thickness, post dimensions, and the way panels seat into routed channels. Trevor Nash has taken apart enough failed Unilock installs in Dallas to know exactly where corners get cut: shallow footings, skipped gravel, and wrong-material fasteners. We’ll get into that below.
Which Unilock Models This Applies To
Unilock makes several fence and screen wall systems, and the part you need depends on which line you have. The main ones we see across Dallas yards are the Estate Wall system, the Roman Stack and Ledgestone lines for decorative screen walls, and their panel-style privacy fencing that uses Unilock’s Tru-Scapes post caps and rail systems. Each line has its own post dimensions and panel thickness, which matters when a section fails and you assume any replacement part will fit.
Start by checking the end of a post or the inside face of a panel for a molded label. Unilock embeds a small ID stamp on most components. If the label is worn off, measure the post outside dimension: Unilock privacy fence posts are commonly 5″ x 5″ or 4″ x 4″ square, and panel thickness usually runs between 1.25″ and 2″, depending on series. Do not guess. We’ve seen homeowners order an aftermarket 4×4 post sleeve for a system that needed a Unilock-specific 5×5 with a routed channel, and the panel won’t seat. It’s a hundred-dollar mistake that turns into a full section rebuild.
For Unilock fence repair, we recommend OEM Unilock components when the fence is under ten years old and still in production. For older lines Unilock has discontinued, a quality aftermarket post or panel matched to your measurements works fine, as long as the wall thickness and UV stabilizer match. Texas sun is brutal on vinyl that wasn’t compounded for it. Cheap aftermarket parts chalk and crack in three to five years here, which is exactly the call we get from homeowners who used the cheapest fix last time.
Styles & brands we work with
Signs Your Unilock Fence Installation Is Failing
- Post lean at the base. This is almost always a footing problem, not a post problem. In Dallas’s expansive clay, a post set in a 24-inch hole with no gravel base will heave with every wet-dry cycle. We see it most in Lake Highlands and Richardson, where the clay gets particularly squirrelly.
- Panels pulling out of the post channels. Unilock panels slide into routed channels in the posts. If a channel cracks or the post twists in the soil, the panel will pop out on one side. Wind load makes this worse. The fix is usually a new post, reset at proper depth with gravel and concrete.
- Bottom rail sagging between posts. This one’s common on wide panel spans, especially 8-foot sections. The rail may be fine; the posts are leaning outward under the panel weight. We check post spacing and footing depth before blaming the rail.
- White chalk on the surface. UV degradation. Every vinyl fence chalks eventually, but Unilock’s compounds are built to resist it for 15 – 20 years in Texas. If you’re seeing heavy chalk at year six or seven, the panel was likely an aftermarket substitute or the fence wasn’t Unilock at all.
- Gate sag or latch misalignment. Fence gates take the most abuse, and Unilock gates are no different. A sagging gate stretches the hinge area and cracks the post face. We rebuild gate posts with additional concrete and often switch to heavier gauge hinges than the original.
Replacement Cost & What’s Included
Dallas Unilock fence installation runs $3,500 – $9,000 in our experience. The spread mostly comes down to three things: how many linear feet of fence you’re replacing, whether the posts need to be dug and reset (versus just swapping panels), and access. If we’re hand-carrying materials through a gate because the side yard is too tight for equipment, that’s time and labor.
Here’s the line-item picture on a typical 60-foot Unilock fence replacement in Dallas:
- Old fence removal and haul-away: $500 – $900, depending on what’s back there. We’ve pulled out chain link, rotted cedar, and once a fence made of pallet wood.
- Post excavation and new footings: $1,200 – $2,200. We dig below frost line, set in gravel, and use the right concrete mix. This is where cheap installs fail, which is why we don’t skip it.
- Unilock panels, posts, rails, caps, and gate hardware: $1,500 – $4,000. OEM parts cost more than aftermarket, and gate posts with hardware push toward the top of that range.
- Labor and finish work: $800 – $2,000. That includes post leveling, panel seating, gate adjustment, and cleanup.
Every fence job from Penhallow Remodeling Dallas gets a written price before we show up, so the number on day one is the number on the invoice. No change orders because we discovered something we should have seen in the quote. And if a post shifts or a panel comes out of the channel within a year, the 365-Day Done Right Promise covers it in writing. We come back, fix it, no charge.

You can safely check a few things yourself. Walk the fence line and look at the ground around each post. Push lightly on the post at shoulder height; if it moves more than a quarter inch at the base, it’s a footing issue. Check whether panels are seated fully in their channels, and look for cracks spreading from the routed slots. That tells us a lot about whether we’re quoting a repair or a replacement before we ever dig.
Where DIY goes wrong on Unilock fence work in Dallas is the footing. Setting a fence post properly in expansive clay takes more than a post-hole digger and a bag of Quikrete. You need the hole below the active soil zone, a compacted gravel base, and the right concrete mix for the soil type. If you’re replacing a single post next to an existing fence, you also have to match the old line exactly or your panels won’t seat. We’ve fixed enough DIY post settings in Oak Cliff and North Dallas to know the attempt usually costs more than calling us first. Give you a number before I pick up a tool, that’s the only way I know how to start. Call us at (940) 204-5368 and we’ll come look at the fence, give you a written number, and tell you what actually needs to be done.
FAQs
A properly installed Unilock fence should last 20 – 30 years in Dallas. The panels carry a UV-stabilized compound that resists Texas sun, and the real longevity factor is the footing: correctly set posts in Dallas clay can keep that fence straight for decades. Footing failures are what shorten fence life here to 8 or 10 years.
Yes, often. A single cracked post or a panel that’s popped out of its channel can usually be swapped without touching the rest of the fence. The catch is matching the existing Unilock line and color, because vinyl color shifts slightly with UV exposure and an off-the-shelf panel won’t always blend perfectly. Call (940) 204-5368 and we’ll tell you honestly whether a repair makes sense or if you’re looking at a section replacement.
Most Dallas Unilock fence replacements run 2 – 4 working days from tear-out to final gate adjustment. Single post or panel repairs are usually a half-day. We give you a real arrival window before we start, and the schedule we quote is the schedule we keep.
We keep common Unilock post caps, rail brackets, and gate hardware on the truck for repair calls. Full panels and posts are ordered per job from our Dallas supplier, with OEM Unilock parts specified whenever your fence line is still in production. If you’re not sure what you have, we’ll identify it on site and quote you a written price before any work starts.
