Jerith Construction in Sherman Oaks, CA | Rowan Construction Group Sherman Oaks
We provide independent Jerith aluminum fence and railing service across Sherman Oaks, not as a manufacturer-authorized dealer but as a local construction firm that has spent years learning how Jerith systems fail on Valley properties. The one thing that makes our Jerith work here different: we know how to set posts plumb and rack panels true on lots whose grades never fully stabilized after the 1994 Northridge earthquake. Call (213) 221-0788 to schedule your free estimate.
Why Sherman Oaks Residents Choose Us for Jerith Service
We’ve been working with Jerith sales & service long enough to know the difference between a panel that needs re-racking and a run that needs full replacement. Our crews handle Jerith Imperial, Provincial, and Majestic Series aluminum fence systems, plus Regal Series railing, on the specific property types that dominate Sherman Oaks service area: post-WWII slab-on-grade ranches, 1960s soft-story dingbats with tuck-under parking, and hillside cut-and-fill lots climbing toward Mulholland Drive.
Grant Rowan grew up in Los Angeles and has spent the better part of three decades doing construction work across the San Fernando Valley. He studied construction technology at Los Angeles Valley College in Valley Glen, where he learned to read structural drawings before he ever swung a framing hammer on a paid job. That background shows up in how our crews work: we document every footing depth, every post plumb reading, every fastener torque spec in a photo record you receive as standard - not as an upgrade. Under Clause 1 of the Haven Standard, the price is written before anyone starts. Measure twice, write it down, then build it.
We stock genuine Jerith replacement panels, pickets, gates, and hardware for color- and profile-matched repairs. When OEM pieces are backordered, we use quality aftermarket posts and self-drilling stainless fasteners that meet or exceed Jerith’s spec. We repair when the powder coat is intact and the posts are plumb; we recommend full replacement when rust-through or footing failure has compromised multiple sections. No work proceeds on a change until the change order is signed - the discipline that has kept our projects within a few percent of the agreed price since 2007.
Common Jerith Construction Problems We Solve in Sherman Oaks

- Powder-coat chalking and fading on south-facing runs. Sherman Oaks sits deep in the Valley heat basin, regularly hitting 100°F-108°F in summer - 15-20 degrees hotter than coastal LA. That UV load breaks down Jerith’s polyester powder coat years ahead of schedule, especially on south- and west-facing fence lines. We assess whether spot repair with color-matched panels makes sense or the whole run needs stripping and recoating.
- Rackable panel hardware binding at grade changes. Hillside parcels above the 405/101 interchange involve cut-and-fill grading that leaves fence lines with uneven drops. Jerith’s rackable panels are designed to accommodate slope, but the racking hardware binds or shears when the grade change exceeds design tolerance or the footing settles unevenly. We re-grade, reset posts, and re-rack to spec.
- Hidden fastener corrosion at stucco interfaces. The 1950s-1960s ranch homes that dominate Sherman Oaks use stucco-over-wood-frame construction. Where Jerith fence sections meet these walls, the original fasteners often galvanic-corrode from moisture trapped in the stucco membrane. We drill out compromised screws and install self-drilling stainless replacements with proper weep clearance.
- Post footing heave and rotation. Expansive Valley soils plus ongoing seismic movement - Sherman Oaks was among the most damaged communities in the 1994 Northridge quake - cause posts to tilt or rotate out of plumb. This is especially common on slab-on-grade and soft-story properties where the original footing was shallow or the grade has shifted since installation. We excavate to 24-inch minimum depth, use high-strength concrete, and verify plumb before the set cures.
- Gate misalignment from settled retaining walls. Many Jerith gates in Sherman Oaks were installed during post-quake rebuilds on lots with retaining walls that continued settling for years. The gate frame twists; the latch misses the strike. We diagnose whether the gate itself is square or the post has shifted, then correct accordingly.

AfterJerith Service in Sherman Oaks: What Local Conditions Mean for Your Equipment
Because Sherman Oaks was among the most severely damaged communities in the 1994 Northridge earthquake and sits about five miles from the epicenter, many Jerith fences here were originally installed during post-quake rebuilds on lots whose grades and retaining walls never fully stabilized. That matters more than most homeowners realize. A fence post set plumb in 1996 may read two degrees off today - enough to bind a rackable panel or stress a gate hinge. On a 1960s ranch-style home off Moorpark Street, our tech replaced a 60-foot run of Jerith Imperial Series aluminum fence whose powder coat had chalked white and whose rackable panels had bound at a settled footing. We reset the post in fresh concrete, swapped in color-matched Imperial pickets and hidden fasteners, and re-racked the panels so the gate cleared the stucco wall - the homeowner got a seismic-era fence that finally swings true again. Contractors who treat Sherman Oaks like any other Valley suburb miss this history. We don’t.
Jerith Models & Products We Service in Sherman Oaks

We work with the full Jerith residential and light-commercial aluminum lineup. The Imperial Series - the three-rail picket style seen on most Sherman Oaks single-family homes - accounts for roughly half our Jerith calls. The Provincial Series with its narrower picket spacing shows up more on soft-story apartment buildings where code requires reduced climbability. Majestic Series ornamental fence, with its pressed-spear tops, appears on perimeter security runs for hillside properties in the High Fire Hazard Severity Zones above the 101. Regal Series railing handles decks and balconies on garage conversions and ADUs, a growing share of our Sherman Oaks work.
We keep Imperial and Provincial panels, pickets, and hidden fastener kits in stock for same-week turnaround on most repairs. Majestic and Regal components we order to match, with genuine Jerith color samples on hand so you’re not guessing between “black” and “textured bronze” from a screen.

FAQs - Jerith Construction in Sherman Oaks
Yes, if the post footing is intact and the surrounding panels haven’t stressed the rails. We excavate, re-plumb, and re-pour - typically half a day. Call (213) 221-0788 and we’ll assess whether it’s a post issue or a symptom of broader grade settlement.
The San Fernando Valley heat basin hits 100°F-108°F regularly in summer, with UV intensity that degrades polyester powder coat years ahead of schedule, especially on south-facing runs. Chalking is surface oxidation; it doesn’t mean the aluminum is compromised, but the aesthetic protection is failing. We evaluate whether spot panel replacement or full-run recoating is the better value.
Jerith aluminum panels meet most soft-story retrofit perimeter requirements, but the post footing must clear parking columns and utility trenches common to 1960s dingbat construction. We pull permits and coordinate with your structural engineer’s moment-frame drawings. Call (213) 221-0788 for a site review - estimates are free.
Yes. Hillside properties above the 405/101 interchange fall within LA’s High Fire Hazard Severity Zones, requiring fire-resistant construction assemblies under the LAMC. Jerith aluminum is non-combustible; we specify gate hardware and latching systems that meet the same standard, with permits pulled and inspections passed as part of our scope.
Many Jerith fences here were installed during post-1994 rebuilds on lots with unsettled grades and retaining walls that continued shifting for years. Post plumb and footing depth matter more in Sherman Oaks than in neighboring Valley cities. We account for this with deeper excavations, higher-strength concrete, and post-installation documentation you can reference if movement occurs later.
