Unilock Fence Installation Nationwide

Unilock Fence Installation: The Santa Clarita Owner’s Guide

We stock and install Unilock-compatible fence systems across Santa Clarita, with typical installed prices running $3,500-$9,000 depending on linear footage, grade conditions, and the specific Unilock series you select. Most Santa Clarita homeowners who call us notice the problem first as leaning posts, gate sag, or panels pulling away from the retaining wall after Santa Ana wind events. The underlying issue is usually that the original installer set posts in concrete without accounting for the expansive clay soils in Valencia and Saugus, or used standard-grade hardware where Unilock’s specification calls for heavier-gauge brackets.

Which Unilock Models This Applies To

Unilock does not manufacture fence panels themselves; they engineer the structural retaining wall systems and paver bases that residential fences mount to or abut. The relevant product lines we work with in Santa Clarita are the Concord Wall, Brisa Wall, and Pisa2 systems, plus the U-Cara Multi-Face when it carries fence load. The critical spec is the fence-post sleeve detail in Unilock’s construction detail sheets: a 4×4 or 6×6 post must sleeve into a galvanized steel bracket anchored to the wall core, not surface-bolted to the facing unit.

To identify what you have, check the wall base for a stamped date code (usually on the rear face of the bottom unit) and measure the post bracket gauge: Unilock specifies 14-gauge minimum for Santa Clarita’s 85 mph wind exposure zone. Many original installers substituted 18-gauge retail hardware to save $8 per post. We stock both the OEM Unilock bracket kits and heavier 12-gauge equivalents from Simpson Strong-Tie for retrofit jobs where the wall itself is sound but the hardware failed. Rowan Construction Group Santa Clarita is an independent service provider; we are not affiliated with Unilock.

Signs Your Unilock Fence Installation Is Failing

• Gate drags or won’t latch after dry spells. The clay soils in Stevenson Ranch and Sand Canyon shrink dramatically in summer, tilting the post footing. The gate frame itself is usually fine; the post has rotated in its sleeve.
• Horizontal rails pulling out of post mortises. Unilock-compatible vinyl and composite rail systems use a tongue-and-groove joint that depends on the post remaining perfectly plumb. Once the post leans 2 degrees, the rail end bears on one corner and cracks.
• Wall facing units cracking at the post location. This means the post was anchored through the facing rather than sleeved into the wall core. The freeze-thaw cycle in Santa Clarita’s 40-degree winter swings concentrates stress at that point.
• Corrosion staining running down from bracket points. The original installer likely used zinc-plated hardware where Unilock’s detail calls for hot-dip galvanized in coastal-influence zones. Santa Clarita’s morning marine layer accelerates the difference.
• Fence line visibly bowed between posts. Either the post spacing exceeded 6 feet on center for the rail span, or the backfill behind the Unilock wall settled and the fence followed it down. We see this most on homes built during the 2015-2019 boom when grading was rushed.

Replacement Cost & What’s Included

The spread depends on three factors: whether we can reuse the Unilock wall core or must rebuild it, whether the original fence profile is still manufactured (some 2016-2018 vinyl colors have been discontinued), and the access conditions on your lot. Hillside grades in Canyon Country add labor hours for material handling. Every quote we deliver in Santa Clarita is a flat written price with line-item scope, signed before work starts under Clause 1 of The Haven Standard. The 365-Day Done Right Promise covers the installation; hardware carries the manufacturer’s warranty, which we register for you.

DIY or Call Us?

What you can safely check yourself: the bracket gauge with a magnet and caliper, the post plumb with a 4-foot level, and whether the wall drainage zone behind the units is clogged with mulch or soil. What goes wrong fast: cutting into a Unilock wall core to reset a post sleeve compromises the structural integrity of the entire run, and matching the facing unit color after disturbance is nearly impossible without the original batch code. The concrete footing for a 6-foot privacy fence post in Santa Clarita clay needs to hit 24 inches minimum with a bell-bottom base; anything less will heave within two wet-dry cycles. If you’re unsure whether the wall itself is sound, call (747) 294-3985 and we’ll photograph the condition, document what we find, and give you a written price before anyone picks up a tool.
