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 fence built with Unilock pillars, posts, or wall systems, and most jobs are finished in 2 to 4 days once materials are on site. We stock Unilock-compatible fence components and matching hardware, and we can usually schedule your installation within the week. What we see most often: a homeowner notices a leaning pillar after heavy rain, a cracked cap on a fence column, or hairline separation where a Unilock wall meets a gate post, and they want it matched to the existing product before the problem spreads.
Which Unilock Models This Applies To
Unilock fence installation in Los Angeles usually involves one of three product families: the Estate Wall system for low border fencing, the Pisa II or Pisa III stackable wall units for pillars and seat walls, and Brussels Dimensional stone for full-height fence columns that carry aluminum or wood infill panels. The compatibility gotcha we run into constantly: pillar caps and coping units are series-specific. A Pisa II cap will not seat properly on a Pisa III column core, and mixing them leaves a ledge that collects water. We identify the right match two ways: the embossed code on the underside of any loose cap or unit, and the column’s outside dimension, which Unilock sizes in 50 mm increments across the Pisa line.
On the OEM-versus-aftermarket question: for Unilock specifically, we recommend OEM units for any visible face, pillar cap, or corner return. The color lots, surface texture, and edge chamfer are proprietary, and an off-brand equivalent reads as a patch job from ten feet away. For internal column cores and base courses that get buried or covered, quality aftermarket block in the same dimensional range works fine and trims cost. We’re an independent service provider, not a Unilock dealer, so we’ll give you that answer straight rather than upselling you on branded material where it doesn’t matter.

Signs Your Unilock Fence Installation Is Failing
- Leaning pillar at the gate post: This almost always means the concrete footing was undersized for the column’s leverage load. In Los Angeles’s expansive clay soils, we see footings heave in winter and settle in summer, and a pillar starts walking within two years. The fix requires resetting the column core, not just shimming the cap.
- Hairline cracks across cap units: Freeze-thaw isn’t the culprit in LA, thermal cycling is. Caps heat to 140°F on a summer afternoon and cool overnight, and without a flexible adhesive bond at the cap-to-core joint, the rigid mortar fails. Hairline cracks are the early warning before a cap splits entirely.
- White mineral streaking on the column face: This is efflorescence, water moving through the block and carrying salts to the surface. It tells you water is getting into the core, usually through a failed cap joint or an interior drainage void. It’s not cosmetic, it’s structural decay in slow motion.
- Gate dragging or binding on the post side: When a Unilock column shifts even a half inch, the gate hardware mounted to it goes out of plane. The latch stops engaging cleanly and the hinges start wearing unevenly. Chasing the gate adjustment without fixing the column just re-breaks every few months.
- Gap widening between the fence panel and column: Wood and aluminum panels expand and contract at different rates than concrete unit. If the gap opens beyond the original reveal and stays open, the column has moved. It’s the earliest measurable sign, and the cheapest one to correct.

AfterReplacement Cost & What’s Included
Fence installation with Unilock products in Los Angeles runs $4,130 to $10,620 depending on linear footage, column count, and whether we’re replacing just pillars or building the entire fence run. A single pillar rebuild with new core, cap, and footing lands between $1,200 and $2,800. Full fence runs with Unilock columns and aluminum infill panels sit at the higher end. We deliver a written price before any work starts, and it includes material, labor, haul-away of the failed units, and a written guarantee for 365 days from completion date. If the work fails inside that year, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and we don’t write it as a promotion, we write it as the terms.
DIY or Call Us?
You can safely check the cap joints, measure the column lean with a level, and photograph any cracking so you have a record of when it started. What you should not do is reset a leaning pillar, regrout a cap, or pull a post core on your own. A Unilock column at the top of its run is heavy enough to crush a hand or foot if it lets go while you’re working it, and footing excavation near buried utilities in Los Angeles requires a locate call you won’t want to manage solo. We’ve reset columns homeowners tried to shim with paver base and construction adhesive, and the second repair costs more than the first one would have. If you’re seeing any of the signs above, call (803) 680-2547 for a free estimate, and we’ll tell you what’s actually happening before you spend a dollar on material.
FAQs
A properly installed Unilock fence column and wall system lasts 25 to 40 years in Los Angeles’s climate, with the first real maintenance point usually being cap resealing around year 12 to 15. Poor footing drainage is what cuts lifespan short, which is why we compact base rock and set a drainage column inside every core we build. Call (803) 680-2547 if your fence is under-performing and we’ll assess what’s left in the structure.
Yes, if the crack is in the cap or a single face unit and the column core hasn’t shifted, we can replace just the damaged unit and re-bond the cap, typically for a fraction of the full rebuild cost. If the footing has moved, patching the face won’t stop the underlying failure and we’ll recommend the reset. A written quote tells you which situation you’re in before any work begins, and estimates are free.
Most Unilock fence installations in Los Angeles take 2 to 4 days on site, with the footing cure eating the schedule time between day one and final cap placement. Single pillar rebuilds are often a one-day job. We’ll give you a start date and a completion window in writing, and the crew’s names and photos before they arrive.
We stock common Unilock Pisa II and III caps, Estate Wall units, and column cores in the Los Angeles colors we install most: Sierra, Sandstone, and Slate. Specialty colors and Brussels Dimensional sizes are ordered direct with 5 to 10 business days lead time, and we handle that order so you’re never chasing a supply house yourself. Call (803) 680-2547 with your model and we’ll confirm availability on the spot.
