Unilock Fence Installation: The Los Angeles Owner’s Guide
Unilock fence installation in Los Angeles typically runs $4,130 to $10,620 for a complete post-and-panel system, including concrete footings, leveling, and alignment. We stock the full line of Unilock fence components and can usually match most Los Angeles-area installations within a few days of your call. Most homeowners discover their fence is failing not when it falls over, but when a post starts leaning after heavy rain softened the soil around the footing, or when a panel shifted out of alignment after a small earth tremor and never sat right again.
If your Unilock fence post is wobbling in its footing, a panel has cracked at the interlock point, or the capstones have loosened to where they rattle in the wind coming off the Santa Anas, you’re in the right place. We’ll walk you through exactly what’s wrong, what it costs to fix in Los Angeles, and how to know whether you need a partial repair or a full reinstallation.
Which Unilock Models This Applies To
Unilock fence systems break into two families: the Estate Wall and pillar-style systems, and the more common modular fence posts and panels used in residential Los Angeles backyards. The Estate Wall system uses a tongue-and-groove block design where each panel locks into a channel cut into the post itself. The modular fence system uses rectangular concrete posts with vertical channels on two faces, and flat panel sections that slide down into those channels and stack.
Here’s the compatibility detail that catches people: Unilock changed the channel width on certain fence post models in 2018, so panels from an older post may not seat cleanly into a newer post without a shim, and forcing them usually cracks the panel corner. If your fence dates from before 2018 and you need a replacement post, we match the original channel spec rather than assuming today’s post will fit. Bring us a photo of the post cap or the stamped code on the inside lip, and we can usually confirm the series before we ever roll a truck.
For the OEM-vs-aftermarket question: Unilock’s own replacement panels are cast from the same molds and match your existing color run, which matters if you’re patching a fence that’s been aging in the Los Angeles sun for six years. Aftermarket copies sometimes run a shade lighter or a hair thinner, which you’d only notice in the middle of a long fence line where old meets new. We use OEM Unilock parts wherever possible, and we’ll tell you plainly when an aftermarket equivalent will get you 90% of the look for 60% of the cost.
Styles & brands we work with
Signs Your Unilock Fence Installation Is Failing
- Post lean after rain. Los Angeles clay soil swells when it’s wet and shrinks when it dries. Undersized footings heave and settle, and the post starts drifting. The fix is re-setting the post in a deeper footing with compacted gravel, not straightening it and hoping.
- Panel chatter in wind. A panel that rattles when the Santa Anas kick up means the stack has shifted and the overlap at the interlock is loose. Left alone, wind vibration grinds the concrete faces together and widens the gap.
- Capstone lift or rotation. Unilock capstones are glued with exterior landscape adhesive. Sun and heat break that bond down over time, especially on west-facing fence lines, and the cap starts working loose.
- Hairline cracks at the channel. If a panel develops a crack running up from the corner where it sits in the post channel, that’s a compression crack. It usually happens when the post shifted and pinched the panel, or when a footing moved from saturated ground.
- Fence line drifting out of level. Walk the fence line and sight down the top. If the caps step up and down like a staircase, multiple footings have settled unevenly, and the problem will only progress.

AfterReplacement Cost & What’s Included
The $4,130 to $10,620 range we quote for Unilock fence installation in Los Angeles covers what your specific job needs: replacing a short run of panels and resets at the low end, to a full perimeter fence with new footings, gravel bases, and capstone replacement at the top. A typical Los Angeles backyard fence line of 40 to 60 linear feet with some post resets and new caps generally lands between $5,500 and $8,000 installed.
What drives the number: how many posts need re-setting versus full replacement, access to the work area (a side gate that’s 30 inches wide changes how we move stone), and whether the original footing depth is adequate. You get a written line-item price before we start, not an estimate range and not a verbal ballpark. The number on that first day is the number on the invoice.
Every installation carries our 365-Day Done Right Promise in writing. If a post settles, a cap lifts, or an interlock fails inside that year, we come back and make it right at no charge. No service call, no re-inspection fee. That’s part of The Kingswell Way we’ve operated under since 2004.
DIY or Call Us?
You can safely check a few things on your own: note which posts lean and which direction, check if the capstones wiggle when you press them, and look for cracks running up from panel corners. What you shouldn’t do is pull panels from an existing Unilock fence yourself, because these panels weigh between 45 and 80 pounds each. A panel that binds in a misaligned channel and then suddenly drops can crush fingers or break a foot, and getting panels in and out cleanly usually takes two people and some finesse, especially with older posts where the channels are gritty and tight.

FAQs
A properly installed Unilock fence with deep footings and good drainage will last 25 to 40 years in Los Angeles, with the panels themselves rarely failing before the footings do. The capstones and adhesive joints are the first things that need attention, usually at the 8 to 12 year mark. Call (213) 277-6578 if your fence is older than ten years and you’re seeing cap or alignment issues, we’ll tell you what’s urgent and what can wait.
Yes, in most cases a leaning post can be plumbed and re-anchored in a new concrete footing without replacing the post itself, and that’s usually what we recommend. The exception is a post with a cracked channel or a post that’s shifted so far it’s pinched the adjacent panels, which is cheaper to replace than to chisel apart. We’ll show you which situation you have before you commit.
Most partial repairs and post resets are finished in one to two days on site, and a full fence line installation generally takes three to five working days in Los Angeles, depending on access and how much old footing concrete has to come out first. You’ll get a defined arrival window when we schedule, not a “somewhere between Tuesday and Thursday” answer.
We stock the common Unilock fence panels, posts, and capstones for the modular and Estate Wall series, and we order the less common trim pieces and color runs directly through Unilock with a lead time we’ll give you up front. You’ll never have to chase down the parts yourself. We also work with a range of other recognized trade brands including KraftMaid, Cambria, and Silestone, so if the project scope grows, the same crew and the same written-pricing standard covers it. Give us a call at (213) 277-6578 for a free estimate on your Unilock fence repair or installation.
