Unilock Fence Installation: The Santa Clarita Owner’s Guide
Unilock fence installation in Santa Clarita typically runs $3,500 to $9,000 for a standard residential perimeter, and most standalone post or panel replacements land in the $400 to $1,800 range depending on how much of the run came down. We stock Unilock-compatible posts, panels, and base materials on our trucks, and we can match most existing Unilock fence lines without ripping out the whole system. The way most Santa Clarita homeowners find out a fence section has failed is simple: one morning the gate swings low, or a post is leaning after a Santa Ana wind event, or the base course has shifted and a panel is now visibly out of level.
If you’re reading this with a fence section already on the ground or wobbling at the post, you’re in the right place. Here’s exactly what fits, what fails, what it costs, and what we do differently.
Which Unilock Models This Applies To
Unilock fence systems are built around modular concrete posts and panels that slide into a channeled post design. The two lines we see most often in Santa Clarita backyards are the Estate Wall and the traditional post-and-panel fence line. The Estate Wall uses larger-format panels with a more prominent bevel, while the standard line runs a tighter panel profile. The compatibility gotcha that trips up most DIY replacements: post channel widths are not universal across Unilock product generations. An older post from the early 2010s has a narrower channel than current production, so a new panel will not seat correctly even if the face dimensions match. Measure the channel opening before you buy anything. If it reads 2 inches wide, that’s the older post. If it’s 2.5 inches, you’re on the current production.
We source OEM Unilock components where still available, and for discontinued colorways we use a matched aftermarket concrete panel with the same compressive strength rating and a color blend tinted to the existing run. Concrete ages in the Santa Clarita sun, so a brand-new OEM panel next to a 12-year-old fence will always read slightly brighter. We account for that and blend tint before install. Sawyer Remodel Santa Clarita is an independent contractor and not affiliated with Unilock, which matters because you get pricing and scheduling from us directly, not through a dealer network.

Signs Your Unilock Fence Installation Is Failing
- Post lean at the base course. Santa Clarita’s clay-heavy soil expands and contracts through dry-wet cycles. When the base course shifts, the post tilts and the panel above binds in the channel. This is almost always a base failure, not a panel failure.
- Panel cracking at the corner. Uneven settling puts the panel in tension, and concrete fails in tension before compression. A diagonal crack from the corner of a panel is the tell that the load path changed underneath it.
- Gate dragging or failing to latch. A sagging gate on a Unilock post usually means the hinge side post has rotated off plumb. Swapping the hinge does nothing. The post needs to be reset and re-leveled.
- Channel spalling or chipping at the post face. When water gets into the channel and freezes, or when a panel shifts and impacts the channel lip, the concrete face starts to flake. If the spalling extends into the channel, the panel will never seat tight again.
- Visible gaps between post and panel. A panel that rattles in the channel has either worn the channel face or the post was never backfilled tight. Over time that movement compounds, and the panel will crack at the top edge.

AfterReplacement Cost & What’s Included
For a full Unilock fence installation in Santa Clarita, budget $3,500 to $9,000 depending on linear footage, access, whether we’re reusing an existing base course, and the panel profile. If you’re replacing a single damaged post or panel, the range is $400 to $1,800 parts and labor. The spread covers site conditions more than anything else: a fence on a flat Valencia lot with direct access costs less than a hillside run in Stevenson Ranch where every post hole hits rock or hardpan.
Every quote we write is a fixed line-item price. Parts, labor, base material, haul-off of the old concrete, and a written workmanship warranty are on the invoice before we start. No change orders because we hit a root or found an old footing. The number you approve is the number you pay. Luca Romano runs every Santa Clarita fence estimate himself, so the quote you get is from someone who has reset hundreds of concrete posts in this valley, not a sales rep with a tablet.
DIY or Call Us?
You can safely check a few things yourself: measure the post channel width, check for visible cracking at the base course, and note whether the post plumb has moved. What you should not do is try to reset a loaded concrete post without the right lifting plan. A Unilock post with a full panel run above it weighs more than most homeowners expect, and when it drops or slips, it doesn’t just damage the fence. It can crush a hand or foot in a second. We use vacuum lifters and panel carts on every Unilock job, and that equipment is half the reason the install goes straight.
If your fence section is leaning, cracked, or on the ground, call us at (661) 592-1977. We’ll get eyes on it, give you a written price, and tell you exactly which parts are salvageable and which need to go.
FAQs
A properly installed Unilock fence in Santa Clarita should hold structure for 25 to 30 years, with the base course being the first thing to need resetting, usually around year 12 to 15. The panels themselves rarely fail unless the load path underneath them changes. Sun fading is cosmetic and doesn’t affect structural life. Call (661) 592-1977 if your fence is showing a lean or base shift, and we’ll tell you whether it’s a quick reset or a larger base rebuild.
Small corner chips and surface spalls can be patched with a polymer-modified concrete repair, but a panel with a structural crack through the body should be replaced. Patch material won’t restore tensile strength in a concrete panel under load, and the crack will telegraph back through. Get a quote at (661) 592-1977 and Luca will tell you honestly if a patch is worth it or if you’re just buying time.
Most single-post or single-panel replacements are done in one day, including base course repair and haul-off. A full fence line replacement runs one to three days depending on footage and whether we’re rebuilding the base from scratch. We’ll confirm the timeline in writing before we start.
We stock standard post and panel sizes on our trucks, and for discontinued Unilock colorways we order a matched aftermarket blend within a few days. We also carry the same base course material and jointing sand specified for Santa Clarita soil conditions. If you need a part matched, call (661) 592-1977 with a photo and the channel measurement, and we’ll tell you same-day what’s available.
