Santa Ana gusts drop off the Santa Susana Mountains straight into Porter Ranch yards, and a fence here has to shrug that off, not just look good doing it.
Pro Vinyl and Aluminum Fencing fabricates both materials in house, wind-braced when a lot calls for it, with a free, no-obligation estimate.


Hillside lots, wind exposure and roomy Porter Ranch yards each change how a fence gets built, from footing depth to panel bracing.
A privacy fence on a flat Porter Ranch Drive lot is a different job than a side-yard run on a graded parcel near Rinaldi Street. Materials, heights, gates and bracing get planned around the actual lot before a post goes in.
Porter Ranch sits at the northwestern edge of the San Fernando Valley, right where Santa Ana gusts funnel down off the Santa Susana Mountains at speeds that have historically topped 70 mph. A fence panel that is fine in a sheltered yard can flex or fail here.
For exposed runs we build with metal inserts inside the vinyl rails: from the yard it still reads as clean vinyl, but the internal bracing is metal, sized to the run and height so it takes the wind this corridor actually sees.
Much of Porter Ranch sits on sloped ground near the Santa Susana foothills, and a fence line that ignores the grade looks wrong and gaps at the bottom. We rack panels to follow the slope in steps or a continuous rake, keeping post spacing and footing depth matched to the terrain so the fence tracks the yard instead of fighting it. Heights run 2 to 8 ft depending on the section and what the lot needs.

Graded Porter Ranch lots bring up pool-code enclosures for backyard pools and wall toppers that raise an existing block wall without a teardown, right alongside the core vinyl lineup: privacy, semi-privacy and picket styles built to the slope.
The aluminum line brings a modern picket or privacy look, finished black, white, or in a tone that reads like wood grain, plus matching gates, whether that is a single walk gate or a wide driveway span.
A handful of factors set the scope on any Porter Ranch job: total footage, fence height, vinyl versus aluminum, how many gates and what width, how much of the lot is sloped versus flat, and whether an old fence needs removing before the new one goes in. A free walkthrough, no obligation attached, turns that checklist into an actual figure, not an estimate pulled from thin air.
Vinyl carries a transferable limited lifetime warranty, and the color runs through the material itself, so wind-driven grit that scuffs a panel will not expose a different color underneath. It also will not yellow in the Porter Ranch sun, and upkeep is a rinse twice a year, nothing more.
Our aluminum line is backed by 20-year material, 10-year coating and 2-year steel-component coverage, finished in powder-coated black, white or a wood-grain tone that suits the hillside setting.
Every install, either material, also carries our own 5-year workmanship warranty, and every gate ships built to the actual opening’s width, whether that means one walk-through door or a full driveway run, ready for an automation kit down the road since we do not supply motors ourselves.
On a graded lot you see the same run twice, from the pad and from the street beneath it. That is the test to hold a swatch against. One palette leaves you room to play, the other keeps it brief.
Three groups do the sorting: four plain solids, a smooth wood grain set of six, four textured blends. Depth of relief is the difference between them, and a run stepped down a slope shows that relief at every level change.
Pro Vinyl and Aluminum Fencing partners with Catalyst, one of the leading vinyl fence manufacturers in the United States. Their US-made vinyl, our custom fabrication and installation, backed by a transferable limited lifetime material warranty.
Black carries most hillside runs, a timber-look grain and white take the rest, and contoured slat answers only in matte black. Not a long list, and it is not padded out. Each is a powder finish, heat cured, holding fast on an exposed pad.
Pro Vinyl and Aluminum Fencing is a trained and authorized SLEEKFENCE™ contractor. SLEEKFENCE™ is a premium-class aluminum fencing brand registered in the USA – their engineered material, our custom fabrication and welded install, with a 20-year material warranty behind it.
An exposed pad puts wind into the height decision, and what the run is screening puts it there too. Grade does the rest, since a boundary stepped downhill sits at one height up top and another at the bottom. A city ceiling sits over it.

Porter Ranch is a neighborhood of the City of Los Angeles, about 25 miles northwest of Downtown at the northwestern tip of the San Fernando Valley, with an estimated population near 30,571. Chatsworth and Northridge sit along its southern edge, Granada Hills lies northeast, and the Santa Susana Mountains rise just north of the neighborhood.
Main corridors include Mason Ave, Corbin Ave, Porter Ranch Drive, Tampa Ave and Reseda Blvd running north to south, and Sesnon Boulevard, Rinaldi Street and State Route 118 running east to west.
The hilly ground below the Santa Susana Mountains gives Porter Ranch some of its Santa Ana wind exposure, with historical gusts reaching 70 mph and a documented history of wind-driven fire risk in the surrounding hillside terrain. Both factors change how a fence gets engineered here: bracing for the gusts, and material choices that hold up on sloped, fire-adjacent ground.
LAMC 12.22 C.20(f) sets the front yard limit at 3.5 ft here, and lets side and rear runs reach 6 ft. Vinyl, being non-masonry, stays permit-free until 10 ft; cross the standard height cap and Planning approval comes into play too, while masonry or concrete construction hits that requirement at just 3.5 ft.
A property inside an HOA answers to two rulebooks at once, and wherever the association sets a tighter limit, that number is the one that governs. Verify current limits with the Los Angeles Department of City Planning before finalizing a design, since setback and corner rules can vary lot to lot.
Every fence built in Porter Ranch, a short side-yard run or a full wind-braced perimeter on a graded lot, follows one fixed sequence: free estimate, written contract, the build itself, then warranty on file, no exceptions.
Nothing about materials, height, bracing or gate count gets decided after the contract is signed.
Someone walks the lot in person, checks the slope and wind exposure, and leaves a real figure rather than a phone guess.
Scope, materials, colors, heights and gate count go into the signed paperwork before the crew ever shows up on site.
Posts go in first, matched to the slope, then panels get racked up the grade, gates hung, old fence hauled off.
Vinyl’s coverage never expires and transfers to the next owner; aluminum keeps its own long-term terms plus our backing.

A vinyl fence in Porter Ranch stays permit-free up to 10 ft, per LAMC 12.22 C.20(f); a masonry or concrete wall crosses that line much sooner, above 3.5 ft, and going past the standard cap needs Planning approval too.
Verify current requirements with the Los Angeles Department of City Planning.
Porter Ranch caps front yard fencing at 3.5 ft under Los Angeles Municipal Code 12.22 C.20(f), while a side or rear run may reach 6 ft.
Confirm your lot’s exact setback lines with the Los Angeles Department of City Planning before ordering materials.
Yes. For exposed Porter Ranch lots we build with metal inserts inside the vinyl rails, so the panel still looks like clean vinyl from the yard while the internal bracing carries the load.
It is sized to the run and height for the wind this corridor sees.
Yes. Many Porter Ranch properties sit on graded hillside ground near the Santa Susana foothills.
Panels get racked to follow the slope, with post spacing and footing depth matched to the grade so the fence line tracks the terrain instead of gapping at the bottom.
An HOA’s CC&Rs can require stricter fence limits than Los Angeles Municipal Code sets, and where the two disagree, the tighter number wins.
Check your HOA’s paperwork alongside the city’s height rules before finalizing a design in Porter Ranch.
Timeline depends on footage, height, material and whether an old fence needs removal first, which is why the written contract spells out a schedule up front.
Sloped sections and wind-braced runs add planning time but not necessarily install days.
