Unilock Fence Installation: The San Diego Owner’s Guide
Unilock fence installation in San Diego typically runs $4,130 to $10,620 installed, and we carry Unilock-compatible components on our trucks for most standard post-and-panel configurations. Most homeowners call us after a post leans, a panel cracks at the base, or the concrete footing has shifted during our wet winters. You’ll usually see the problem before the fence fails completely, and the fix is faster and cheaper when we catch it early.
Unilock makes modular concrete fencing systems designed to handle San Diego’s dry summers and occasional heavy rain. The blocks and posts are engineered for weight and interlock, but the installation is where fences live or die. A fence set on a thin gravel base or with undersized footings will lean within a few seasons, no matter how good the block itself is.
Which Unilock Models This Applies To
We install and repair Unilock fence systems across the standard panel, post-and-panel, and freestanding wall lines most common in San Diego backyards. If you have the original paperwork, look for the product code on page one: it starts with a series letter followed by dimensions in millimeters, like 1800H for an 1,800mm post height. No paperwork? Measure the post width and panel depth, and take a photo of the profile, and we can identify it before we even schedule the visit.
Here’s a compatibility gotcha most people never hear until it’s too late: Unilock fence posts use a specific lip channel on the interior face that accepts only Unilock-manufactured or certified-compatible panels. A generic big-box concrete panel will not seat correctly, and forcing it cracks the edges within months. We source genuine Unilock components and tested aftermarket equivalents that match the channel spec. Mason Remodeling Co San Diego is an independent service provider and not affiliated with Unilock, but we’ve been working with their product lines long enough to know what fits and what doesn’t.

Signs Your Unilock Fence Installation Is Failing
- Leaning post at the corner or gate. This is almost always a footing problem, not a block problem. San Diego’s clay-heavy soil expands and contracts with moisture, and a footing poured too shallow will rotate. The post itself is usually still intact and reusable.
- Hairline cracks running vertical through the panel. This means the panel is bearing weight it was never designed to carry, usually from a shifting footing on one side. If caught early, we can reset the footing and stop the crack from spreading.
- Gap opening between panels. Unilock panels interlock, and a visible gap means the base has settled unevenly. Left alone, water gets into the joint, and freeze-thaw cycles in the winter do the rest.
- Gate dragging or refusing to latch. The post holding the gate hinge has shifted. This is a safety issue as much as a cosmetic one; a heavy Unilock gate swinging on an unstable post can pull the whole section over.
- White mineral streaks on the face. That’s efflorescence, and it signals water moving through the block. It’s not structural by itself, but it tells us the fence is getting wet more than it should, usually from poor drainage at the base.

AfterReplacement Cost & What’s Included
For San Diego homeowners, expect $4,130 to $10,620 for a full Unilock fence installation. The range depends on linear footage, post count, gate hardware, and access to the yard. A short 25-foot run with two posts and one gate lands near the lower end. A 75-foot perimeter wall with a double gate and tight backyard access climbs to the upper end. The biggest variable is almost always soil: if we hit rock or old concrete below grade, digging footings takes longer and costs more.
What’s in our price: removal and haul-away of the old fence section, concrete footings poured to San Diego code depth, the Unilock or compatible components, post caps, gate hardware, and leveling and alignment. Every job comes with our written price before any work starts, and the workmanship is covered for 365 days from the completion date. If something shifts or cracks within that year, we come back and make it right at no charge.
DIY or Call Us?
You can safely check the basics yourself: look for leaning posts, run a level across the top rail, and note any new cracks. That’s where we’d recommend you stop. Unilock fence components are heavy. A single post can weigh 80 to 120 pounds depending on height, and setting one correctly requires a footing at least 18 inches deep in San Diego’s soil conditions, with the post braced square while the concrete cures. Get the depth or alignment wrong and you’ll be doing it again in two years, with a cracked panel thrown in for free.
Tell me what’s broken. I’ll tell you what it takes. If your Unilock fence is leaning, cracked, or losing its line, call us at (619) 673-9302 and we’ll walk through what you’re seeing and whether it’s worth a full repair or a targeted fix. The estimate is free, and you’ll have a written number before we touch anything.
FAQs
A correctly installed Unilock fence system lasts 25 to 40 years in San Diego’s climate, with the posts and footings typically outlasting the panels. The real lifespan killer here is drainage: fences set without a proper gravel base or with footings in constantly wet soil will start shifting within 5 to 8 years. Call (619) 673-9302 if your fence is showing signs early, and we’ll give you an honest read on what’s failing and why.
Small hairline cracks can sometimes be stabilized with the post and footing reset, but any crack that goes through the panel face means replacement. Patching concrete on a modular system is almost always a temporary fix that looks worse than the crack. We’ll tell you straight which path makes sense before you spend a dollar.
A standard Unilock fence replacement in San Diego takes 2 to 4 days from demo to final leveling, depending on the run length and how many footings we’re pouring. Curing adds a day before we hang gate hardware. We schedule the whole job in one visit window, and you’ll know the timeline and the price in writing before day one.
We stock common Unilock post sizes, caps, gate hardware, and compatible panels on our trucks, along with the concrete and rebar needed for footings. For less-common series or color-matched runs, we order directly and typically have them in hand within a week. Most San Diego homeowners never wait more than a few days from estimate to completed repair.
If your Unilock fence needs a reset, a section swapped, or a full install, call (619) 673-9302 and ask for a free estimate. We’ll put the number in writing before any work starts.
