Jerith Construction in Los Gatos, CA | Rowan Construction Group San Jose
We provide independent Jerith fence installation and repair across Los Gatos, working with the brand’s aluminum and vinyl lines in hillside fire zones and historic downtown parcels alike. The one thing that makes our Jerith work here different: we’ve spent years adapting Jerith post-anchor and powder-coat specs to Los Gatos’ dual burden of Chapter 7A fire-resistive requirements and steep, seismically active terrain that flatland contractors rarely encounter. Call (669) 271-8644 to schedule your free estimate.
Why Los Gatos Residents Choose Us for Jerith Service
Grant Rowan grew up in Beverly Hills, made his way to the trades through Santa Monica College’s construction technology program, and spent the better part of two decades running crews across San Jose - including three straight years of residential and light commercial work near Willow Glen. He built Rowan Construction Group on one repeatable idea: document everything, explain what you’re doing and why, and don’t move to the next phase until the current one passes inspection. That discipline is what Haven acquired Rowan for, and it’s how we approach every Jerith fence in Los Gatos.
We are not a manufacturer-authorized Jerith dealer. We’re an independent construction team that has installed and repaired Jerith ornamental aluminum and vinyl fencing across Los Gatos for years, none of it tied to any manufacturer authorization or warranty endorsement. Our crews know Jerith’s racking and post-anchor behavior from the hillside tracts to the historic downtown core. We keep genuine Jerith replacement panels, pickets, and post caps in stock for direct matches, and use quality aftermarket hinges, latches, and concrete anchors where they outperform the original hardware. Under Clause 1 of the Haven Standard, you’ll get a written price before anyone picks up a tool - every time.
Common Jerith Construction Problems We Solve in Los Gatos

- Powder-coat chalking and fading on west-facing hillside runs. Los Gatos sits at the mouth of the Santa Cruz Mountains, so hillside properties catch more coastal fog and UV than the San Jose valley floor just a few miles east. That moisture-UV mix degrades Jerith Elite Series aluminum powder coat faster than inland exposure. We assess whether spot panel replacement or full re-coating is the honest call.
- Post-rack and gate sag on graded hillside soils. The western neighborhoods above Highway 17 near Lexington Reservoir sit on steep terrain shaped by the 1989 Loma Prieta epicenter. Jerith aluminum fences set into expansive clay or graded soils without deepened concrete footings will rack seasonally. We pull old footings and set deeper piers to resist slope movement.
- Vinyl picket and rail brittleness from Diablo-wind thermal swings. Fall Diablo wind events spike fire risk in the WUI zone and deliver rapid temperature swings that stress Jerith Reflections Series vinyl. The material contracts and expands across wider ranges here than in sheltered valley yards, leading to cracked rails and loose pickets.
- Corroded bottom rails and fasteners in older downtown Craftsman yards. The historic downtown core’s 1880s-1910s properties often have irrigation and drip lines that keep soil moisture persistent against Jerith fence bases. We replace corroded hardware with aftermarket stainless fasteners and raise or ventilate bottom rails where the grade allows.
- Gate misalignment after seismic settling or hillside grading. Custom homes built since the 1990s post-Loma Prieta rebuild frequently feature significant site grading that continues to settle. Jerith gates that latched true in year one drift by year five. We re-hang to true plumb and upgrade hinges where needed.

AfterJerith Service in Los Gatos: What Local Conditions Mean for Your Equipment
Because hillside Los Gatos parcels above Highway 17 sit in California’s Very High Fire Hazard Severity Zone, Jerith fence and gate specs here often have to satisfy both Town discretionary design review and Chapter 7A ignition-resistant material expectations - a combination that flatland Campbell or Los Altos jobs almost never face. The Town of Los Gatos Community Development Department requires discretionary design review for most exterior alterations visible from a public street, including new accessory structures and material changes; a contractor used to pulling straightforward permits in Campbell or San Jose will find that a Los Gatos remodel or Bathroom Remodeling in Los Gatos routinely adds 6-12 weeks and an architectural consistency hearing before a shovel hits the ground. For Jerith aluminum fence owners, this means your replacement or upgrade isn’t just a construction decision - it’s a permitting sequence that has to account for ember-resistant venting, defensible-space compliance, and aesthetic review simultaneously. We’ve run this dual-track process enough times to know where the Town’s design review board tends to push back on fence height, color, and placement relative to sight lines from public roads.
In the hillside neighborhood above Highway 17 near Lexington Reservoir, we replaced a 140-foot Jerith Elite Series aluminum fence whose posts had racked and whose powder coat had chalked after years of coastal fog and Diablo-wind cycling. We pulled the old footings, set deeper concrete piers to resist the graded slope, and re-hung the gates so they latched true through the season. The owner also asked us to harden the gate for ember exposure as part of the same WUI-compliant scope.
Jerith Models & Products We Service in Los Gatos

We work across Jerith’s residential lines: the Elite Series and Stafford Series aluminum ornamental fences, plus the Reflections Series and Ashford Series vinyl privacy and picket lines. For Los Gatos, we stock genuine Jerith replacement panels, pickets, and post caps to match existing runs without the month-long factory wait. Our aftermarket hinge and latch upgrades - particularly for gates in the WUI zone where positive latching matters for ember resistance - often outlast the original hardware in this climate. If a Jerith run is more than about 30% failed from soil movement or powder-coat breakdown, we recommend selective section replacement first and full replacement only when the posts themselves have shifted. “Measure twice, permit once, then we talk timeline.”

FAQs - Jerith Construction in Los Gatos
Yes. Chapter 7A requires ignition-resistant materials and ember-resistant construction for fences and gates in the WUI zone, which covers hillside Los Gatos parcels above Highway 17. We specify Jerith aluminum with upgraded post anchoring and ember-resistant gate hardware, and we document the compliance package for Town permit review. Call (669) 271-8644 to walk through what your specific parcel requires.
Los Gatos hillside properties receive more coastal fog and UV cycling than the San Jose valley floor, and west-facing runs take the brunt. The moisture penetrates micro-fissures in the powder coat, then UV breaks down the polymer. We assess whether the substrate is still sound; if so, panel replacement with a higher-grade aftermarket coating may outlast factory spec in this exposure. Call (669) 271-8644 for a free evaluation.
It can. The Town requires discretionary design review for most exterior alterations visible from a public street, including new accessory structures and material changes. A Jerith fence replacement that changes height, color, or placement relative to the street typically triggers review, adding 6-12 weeks before construction. We handle the application package as part of our standard Los Gatos permitting service. Call (669) 271-8644 to confirm whether your specific project requires review.
Yes, in most cases. We stock genuine Jerith replacement pickets and rails for the Reflections Series, and we can match color profiles from recent production runs. For older colors that Jerith has discontinued, we source closest-match aftermarket vinyl and show you the sample before ordering. Call (669) 271-8644 to schedule a match assessment - estimates are free.
It can, particularly if the conversion triggers Town discretionary design review for the overall site. Los Gatos garage conversions and Kitchen Remodeling - Los Gatos projects often require reconfiguring driveway access, which may relocate or remove existing Jerith gates. We coordinate the fence and gate scope with the ADU or conversion permit package so you’re not paying for separate review cycles. Call (669) 271-8644 to schedule a unified estimate.
