Jerith Construction in Berkeley, CA | Rowan Construction Group Oakland
We provide independent Jerith fence installation and repair across Berkeley, from the fog-heavy flatlands to the fault-zone hills. The one thing that sets our Jerith work apart here: we know which jobs need a geologic hazard investigation before the city will even look at a permit, and we know how to anchor posts in shallow pre-1935 perimeter foundations without cracking the original stem wall. Call (628) 300-4376 to schedule a free estimate with a written, line-item price before any work starts.
Why Berkeley Residents Choose Us for Jerith Service
We’ve installed and serviced Jerith ornamental aluminum and vinyl fencing across the East Bay since 2007, including the specific gate hardware, post-cap, and panel-fastening systems Jerith uses. Because we are independent, we can repair a single bent picket or re-hang a sagging gate with the right parts instead of pushing a full replacement.
Grant Rowan, our owner, spent years running jobs through the Fruitvale district and across Berkeley’s varied terrain. He picked up his first framing hammer in a summer trade program at Santa Monica College, then completed the full construction technology curriculum there. That training shows up in how we scope Jerith work: line-itemized estimates, material specs with brand and model noted, and documented inspections at each phase. Measure twice, document everything, then build.
We stock genuine Jerith replacement pickets, rails, post caps, and hinges locally, and we use forged stainless or galvanized gate hardware rather than the pot-metal hinges that fail in Berkeley’s salt-fog air. Our Jerith sales & service covers every model line, with parts on hand for fast turnaround.
Common Jerith Construction Problems We Solve in Berkeley

- Powdery white oxidation and paint chalking on flatland aluminum panels. Marine-layer fog rolls in regularly within a mile of the bay, accelerating the breakdown of older powder coat. We see this most on west Berkeley lots where the fence catches the full brunt of morning condensation. The fix is media-blasting to bare aluminum, a compatible etch primer, and a color-matched topcoat, not a pressure-wash that drives water into the rail channels.
- Rust jacking at post bases in clay-heavy flatland soils. Wind-driven rain through open Jerith picket gaps ponds at post bases set in Berkeley’s shallow, poorly draining flatland dirt. The result: caps lift, anchors loosen, and the whole run leans. We excavate to sound substrate, set a concrete pier with a post-base isolation pad, and rehang with stainless hardware.
- Gate sag from original wood posts on Victorian and Craftsman properties. Many Berkeley homes built between 1895 and 1935 still have their original wood fence posts. A Jerith gate hung on rotted 4×4 redwood will drag within two seasons. We sister in a Jerith aluminum post with a concealed base plate, transfer the gate load, and preserve the historic look without a full rebuild.
- Seismic racking of picket-to-rail welds after Hayward Fault shaking. Even moderate tremors crack powder-coated welds and shear gate-latch screws. The symptoms are easy to miss: a gate that needs an extra shove, panels that rattle in a stiff breeze. We inspect the full rail-to-post connection, re-weld or sleeve as needed, and upgrade to through-bolted latch hardware.
- Fire-rebuild code conflicts in the hills. Tunnel Fire reconstruction lots often have Class-A fire-resistant roofing and ember-resistant vents mandated, but the Jerith fence line gets overlooked. A standard Jerith aluminum fence is non-combustible, yet gate gaps and lattice styles can violate defensible-space rules. We specify solid-panel or tight-picket Jerith Infinity series where WUI compliance is required.

AfterJerith Service in Berkeley: What Local Conditions Mean for Your Equipment
In Berkeley’s hills, any Jerith fence or gate install within roughly 50 feet of the mapped Alquist-Priolo Hayward Fault trace can require a site-specific geologic hazard investigation before the city issues a permit. Flatland jobs instead face shallow pre-1935 perimeter foundations that dictate whether a Jerith post can be anchored to the existing footing or must be set in a new concrete pier. These are not interchangeable conditions, and an out-of-town contractor who treats them as such will lose months to permit rejection.
We learned this on a Tunnel Fire rebuild lot where a homeowner needed a Jerith aluminum privacy fence along a slope that crossed near the fault trace. We pulled the geologic hazard documentation, set the uphill posts on engineered concrete piers rather than the existing shallow footings, and re-hung the gate with stainless hinges after the old ones had seized in the salt air. The fence line passed the city’s fault-zone review without a redesign. That’s the difference between a contractor who has worked Berkeley service area jobs and one who has not.
Jerith Models & Products We Service in Berkeley

We work across the full Jerith residential and light-commercial catalog:
- Jerith Traditional aluminum fence series: The standard ornamental picket line, most common on flatland Craftsman properties. We stock replacement pickets, pressed-spear tops, and snap-on post caps in black, bronze, and white.
- Jerith Infinity aluminum fence series: Heavier-wall rail and concealed fasteners, specified where WUI fire codes or hillside wind loads demand more than the Traditional line. We keep Infinity rail brackets and cover strips on hand.
- Jerith Commercial-grade aluminum fence series: Industrial-duty rail and larger posts for multi-unit Berkeley properties and ADU perimeter separation. We source commercial post flanges and extended-height panels to order.
- Jerith Vinyl fence series: Privacy and picket styles in tan, white, and clay, popular for flatland backyard enclosures where low maintenance matters more than ornamental detail. We carry replacement tongue-and-groove privacy slats and routed post sleeves.
All repairs use genuine Jerith components or OEM-compatible equivalents with matching finish codes. We do not substitute generic box-store pickets and call it close enough.
Jerith Service Pricing in Berkeley
| Service | Typical Range in Berkeley |
|---|---|
| Aluminum Fence Installation | $4,000-$10,000 |
| Vinyl Fence Installation | $3,500-$9,000 |
| Garage Conversion | $30,000-$80,000 |
What drives the cost: linear footage, slope correction, soil condition (new pier vs. existing footing anchor), and whether the job falls inside the Alquist-Priolo zone requiring geologic documentation. Hillside jobs with engineered piers and WUI-compliant materials run toward the upper end; flatland straight runs on level lots with good drainage stay lower.
Every estimate includes a written scope, material specifications with brand and model noted, and our 365-Day Done Right Promise backed by The Haven Standard. Under Clause 1, the price is written before anyone starts. No change proceeds without a signed change order. Call (628) 300-4376 for an exact quote - estimates are free.

FAQs - Jerith Construction in Berkeley
Can I install a Jerith aluminum fence in Berkeley’s hills without a geologic hazard investigation?
No. If the mapped Alquist-Priolo Hayward Fault trace runs within roughly 50 feet of your property line, Berkeley requires a site-specific geologic hazard investigation before issuing any fence permit. We handle the documentation as part of our scope. Call (628) 300-4376 to schedule a free estimate and we’ll flag whether your lot falls in the zone.
Why does my Jerith aluminum fence look chalky and white near the Berkeley flatlands?
Marine-layer fog accelerates powder coat oxidation, especially on older Jerith panels within a mile of the bay. The white residue is degraded resin, not dirt. We media-blast to bare aluminum and recoat with a compatible system. Call (628) 300-4376 for an exact quote - estimates are free.
My Jerith gate sags and drags on the ground - can that be fixed without replacing the whole fence?
Usually yes. Sag comes from failed hinges, rotted wood posts, or seismic shift of the latch post. We replace with forged stainless or galvanized hardware and sister in a Jerith aluminum post if the original wood is compromised. Full replacement is only recommended when damage exceeds roughly 30 percent of the run.
After an earthquake, my Jerith fence panels rattle and the gate won’t latch. What should I do?
Schedule an inspection. Seismic racking cracks picket-to-rail welds and shears gate-latch screws - damage that worsens with every aftershock. We inspect the full connection, re-weld or sleeve as needed, and upgrade to through-bolted hardware. Do not attempt to adjust high-tension gate springs yourself; the stored energy can cause serious injury.
Do you match an existing Jerith fence color and style when doing a partial repair in Berkeley?
Yes. We cross-reference Jerith finish codes and source matching pickets, rails, and post caps from current production or compatible aftermarket stock. Color drift from sun exposure is normal; we blend the repair zone and document the match condition in your photo record. Call (628) 300-4376 for an exact quote - estimates are free.
