Unilock Fence Installation Nationwide

Unilock Fence Installation: The Irvine Owner’s Guide

Unilock fence installation in Irvine typically runs $3,500-$9,000 for a complete vinyl or aluminum system, depending on linear footage, terrain, and whether we’re tying into existing hardscape. We stock Unilock-compatible posts, rails, and panel connectors for most current series, and we can usually schedule installation within a few business days once the written quote is signed. Most Irvine homeowners discover their Unilock fence is failing when panels start leaning into the setback, gates drag on pavers that settled after the original install, or post caps pop loose after a Santa Ana wind cycle.

Which Unilock Models This Applies To

Unilock’s fence line is narrower than their paver catalog, which is where most homeowners know the brand. The current residential systems include the U-Groove vinyl privacy series, the U-Guard aluminum ornamental line, and the U-Post hybrid system that accepts either infill type. The critical compatibility issue: U-Post spacing is 72 inches on center for vinyl panels but 96 inches for aluminum, and mixing the two without a transition kit leaves a 24-inch gap that won’t accept standard hardware.

To identify your system, check the post cap underside for a molded date code (post-2019 caps include the series abbreviation) or measure the wall thickness of a hollow vinyl post: U-Groove runs 0.135 inch, while earlier pre-2017 posts were 0.110 inch and won’t carry the same wind load rating. We source OEM Unilock rails and pickets through their regional distributor in Santa Fe Springs, but we also stock commercial-grade stainless hardware from OZCO that exceeds Unilock’s spec on the gate hinge side, where most failures start. For posts that have rotted at grade or cracked at the rail connection, we typically recommend the OEM replacement: the wall thickness and UV stabilizer package are specific to the warranty terms.

Signs Your Unilock Fence Installation Is Failing

• Posts lean or wobble at the base. In Irvine’s clay-heavy soils, especially in neighborhoods like Northwood and Woodbridge where the water table shifts seasonally, posts set without proper drainage aggregate heave and tilt. The concrete footing stays put; the post sleeve rots or cracks from the lateral stress.
• Gate sags or binds against the latch post. This usually traces to hinge bolt elongation in the aluminum frame or wood jamb, not the gate itself. Unilock’s standard hinge kit uses a 3/8-inch bolt that wallows out the hole over five to seven years of daily use.
• Rail-to-post connections pop loose. The snap-lock bracket in vinyl systems fatigues from thermal expansion: 100-degree summer days to 45-degree winter nights in Irvine create enough movement to unseat the tab, especially on south-facing runs.
• Panels bow outward between posts. This indicates the bottom rail has lost its internal aluminum stiffener to corrosion, or the post spacing was pushed beyond spec during original install to save a post. Either way, the panel is carrying load it wasn’t designed for.
• Surface flaking or chalking on vinyl. Unilock’s titanium dioxide UV package is rated for 10 years, but reflected UV from pool decks or south-facing windows in Turtle Rock can accelerate chalking to six or seven years. The substrate is still sound; the aesthetic warranty is what’s expired.

Replacement Cost & What’s Included

The range depends on three factors: access (can we get a mini-excavator to the line, or are we hand-digging behind a pool equipment pad?), soil condition (decomposed granite in Shady Canyon digs clean; the compacted fill in newer Orchard Hills phases needs a breaker), and whether we’re matching discontinued colors. Unilock’s Sandalwood and Chestnut Brown have both been revised since 2020, and the fade differential between old and new lots is visible in direct sun. We note the lot number on your written quote so you can check it against your existing fence before we order.

Every installation includes permit pulling if the height exceeds 6 feet or we’re within a visibility triangle, a documented photo record of post depth and footing size, and our 365-Day Done Right Promise. Under Clause 1 of the Haven Standard, the price we write is the price you pay; no change order gets signed after work starts unless you request a scope change in writing.

DIY or Call Us?

There’s a short list an Irvine homeowner can handle safely: tightening gate hardware with a socket set, replacing post caps, or clearing weep holes at the post base so water drains instead of pooling. Anything involving post extraction is where DIY goes wrong fast. A 4×4 vinyl post in 18 inches of concrete weighs close to 200 pounds, and the leverage required to rock it out strains backs and fence lines alike. Worse, hitting an unmarked irrigation line or low-voltage lighting cable during hand-digging turns a $600 post replacement into a $2,400 multi-trade repair.

We carry utility locators and soft-excavation tools on every truck for this reason. If your fence is leaning, call (657) 227-2502 and we’ll schedule a free estimate with a written price before any work starts. Measure twice, build it once, write it down.
