Unilock Fence Installation: The Sherman Oaks Owner’s Guide
Unilock fence installation in Sherman Oaks typically runs $3,500-$9,000 for a complete vinyl or aluminum system, with most residential projects quoted as a flat written price before work begins. We stock Unilock-compatible posts, rails, and panel connectors for same-week scheduling across the San Fernando Valley. Most Sherman Oaks homeowners discover their fence needs attention when panels start leaning toward Ventura Boulevard after winter rains undermine the post footings, or when the black aluminum finish chalks white after five or six years of Valley sun exposure.
Which Unilock Models This Applies To
Unilock manufactures fence systems under several series names, and matching the right components matters because the post dimensions and rail profiles are not interchangeable across lines. The U-Gard aluminum series uses 2-inch square posts with a .060-inch wall thickness, while the Concord vinyl privacy line relies on 5-inch square posts with routed pockets for the horizontal rails. The model designation is stamped on the inside face of the post cap, visible once you pop it off with a flat bar.
We source OEM Unilock rails and pickets through Unilock’s western distribution center in Ontario, though we also keep quality aftermarket equivalents on hand for discontinued colorways. The aftermarket posts match the Unilock profile within 1/16 inch, which is close enough for rail engagement but can leave a slight reveal at the cap line. For properties in the hills above Mulholland Drive, where wind exposure is higher, we specify the heavier .080-inch wall post even when the original was .060. That’s a compatibility gotcha most homeowners miss until the second replacement.
Signs Your Unilock Fence Installation Is Failing

- Posts lean or wobble at grade. The concrete footing has cracked or the post base has rotted where soil contact occurs. In Sherman Oaks, the clay-heavy soil along the Los Angeles River floodplain expands when wet and contracts dry, breaking footing bonds over three to five years.
- Rails pull out of post pockets. The rail tenon has cracked or the pocket has enlarged from thermal cycling. Vinyl becomes brittle faster here than in coastal zones because the Valley’s 100-plus summer days accelerate UV degradation.
- Gate sags and drags. The hinge post has settled or the frame has racked. Unilock gates use an internal aluminum channel for rigidity, but if the post leans, the channel transfers stress to the corner welds.
- Surface chalking or color shift. The UV stabilizers in the capstock have depleted. On south-facing exposures along Ventura Boulevard, we’ve measured surface temperatures above 150°F, which halves the expected color retention lifespan.
- Picket tops swell or delaminate. Moisture has entered through end-grain exposure or fastener holes. This is more common on dog-ear styles than flat-top because the angled cut exposes more cross-section to rain.

AfterReplacement Cost & What’s Included
For a typical Sherman Oaks lot, complete Unilock fence installation falls between $3,500 and $9,000 installed. The low end covers 80 linear feet of 4-foot vinyl picket on existing grade; the high end reaches 200 linear feet of 6-foot privacy with aluminum posts, a double driveway gate, and slope work requiring stepped panels.
What drives the spread: soil condition (rocky cuts near the Santa Monica Mountains foothills add auger time), access for material delivery, and whether we’re tying into existing masonry or pouring new footings. Every quote from Rowan Construction Group Sherman Oaks is a flat written price with line-item scope. Under Clause 1 of the Haven Standard, that number is fixed before anyone digs. The 365-Day Done Right Promise covers the installation, and you’ll receive a documented photo record of footing depths and post plumb before we backfill. No change to the scope proceeds without a signed change order, which is the discipline that has kept our projects within a few percent of the agreed cost since 2007.
DIY or Call Us?

An owner can safely check whether a post is plumb with a 4-foot level and whether the footing is cracked at grade. What goes wrong fast: digging near buried utilities in Sherman Oaks, where older neighborhoods off Dickens Street still have unmapped irrigation lines and the occasional surprise clay sewer lateral. Post holes in rocky soil require a two-man auger or breaker, and setting posts to consistent height across a sloped lot is arithmetic that punishes small errors.
We don’t recommend DIY for gate installation. The hinge and latch alignment tolerances are 1/8 inch, and a sagging gate tears itself apart in months.

FAQs
Vinyl fencing in the San Fernando Valley typically lasts 15-20 years, though south-facing installations may show surface degradation at 10-12 years due to UV exposure. Aluminum systems routinely reach 25 years if the powder coat is intact. Call (213) 221-0788 for an exact quote on replacement - estimates are free.
Individual rails and pickets can be swapped if the post structure is sound and the color match is acceptable. We stock common Unilock colors including Sandalwood and White, though discontinued shades may require full-panel replacement for consistency. Call (213) 221-0788 for an exact quote - estimates are free.
Most residential projects in Sherman Oaks finish in two to four working days, depending on footage, slope, and whether we’re removing an existing fence. Permits are not required for fences under 6 feet in Los Angeles, though we verify property lines and utility clearances before digging. Call (213) 221-0788 to schedule.
We carry common post sizes, rail lengths, and hardware for the U-Gard and Concord lines on our Sherman Oaks warehouse shelves, with same-week availability for most repairs. Specialty colors or large-footage jobs order through Ontario with a five-business-day lead time. Call (213) 221-0788 to confirm stock for your specific model.
