CGI Fence Installation: The Los Angeles Owner’s Guide
CGI fence installation across Los Angeles typically runs $4,130 to $10,620 installed, depending on footage, terrain, and whether we’re working with the existing posts or setting new ones. Most owners discover they need us when a gate stops latching, a windstorm pops a panel, or the concrete pour that was supposed to anchor the posts starts pulling loose after a rainy season. The good news is that CGI’s modular design means a failed section rarely means a full tear-out, which is exactly what we’ll figure out before we quote you anything.
We’re Penhallow Remodeling, and while we’re not affiliated with CGI, we’ve installed and repaired enough of their fence systems across the Valley and the Westside to know them cold. And we stock the common replacement hardware on the truck, so the first visit usually isn’t just a diagnosis. It’s often the fix.
Which CGI Models This Applies To
CGI fence products fall into a few families, and the compatibility details matter more than most people expect. The two workhorses we see most in Los Angeles are the CGI Ornamental aluminum series and the CGI Vinyl series. The aluminum panels come in 6-foot and 8-foot sections with either a flat-top or spear-top picket profile. The vinyl runs in 6-foot sections with tongue-and-groove pickets that snap horizontally, and here’s the gotcha: the older CGI Vinyl systems use a thicker wall profile than the ones rolled out after 2018. You can’t always mix old and new sections without a visible seam difference, so we measure the wall thickness before ordering anything.
On the aluminum side, CGI uses a powder-coat finish with a Limited Lifetime Warranty when installed to spec, which is why corrosion is rare here but not unheard of near the coast in places like Playa del Rey or San Pedro. Salt air chews through the coating faster than inland sun. Our rule for Los Angeles: if you’re within three miles of the ocean, we recommend the factory touch-up kit every two years. If you’re in the Valley, you’ll go five-plus. OEM versus aftermarket: for the aluminum pickets and rails, aftermarket equivalents hold up fine and cost roughly 20 percent less. For the vertical posts and gate hinges, we only use genuine CGI. The post-to-panel tolerance is tight, and generic posts will leave you with rattles on windy days.
Signs Your CGI Fence Installation Is Failing
- Gate post lean or sag. The post footer wasn’t deep enough or the concrete cracked at grade. In Los Angeles, our freeze-thaw cycle is gentle, but the real culprit is usually expansive soil in neighborhoods like Porter Ranch and Chatsworth, where the ground swells after winter rain and heaves the post out of plumb.
- Pickets pulling loose at the rail. On CGI aluminum, this is almost always a stripped screw or a worn nylon washer where the picket meets the horizontal rail. It’s a ten-minute fix per picket, but left alone, the wind-flex will oval out the hole and turn it into a panel replacement.
- Gate won’t latch or binds against the frame. The self-closing hinge assembly on CGI gates uses an internal spring that fatigues over time. When it starts to go, the gate drifts either too fast or too slow, then stops meeting the latch. If you’re forcing the handle, you’re accelerating the failure.
- Vinyl panel yellowing or brittleness. Older CGI Vinyl formulas had less UV stabilizer than current production. If you’re seeing chalky residue on your fingers after brushing against it, the panel is degrading and will crack eventually. We don’t patch UV damage. We replace the affected sections.
- Fence line waviness. Stand at one end and sight down the line. If the posts dip and rise, the original installation skipped the string line, or one corner post is settling. Fixing this properly means resetting posts, not just tightening screws.
Replacement Cost & What’s Included
For a CGI fence installation or section replacement in Los Angeles, plan on $4,130 to $10,620 with the common job landing around $6,500 for a 40-to-50-foot run with two gate posts. The biggest drivers are footage, whether we’re pulling and resetting posts or working in the existing ones, and what kind of access we have. A hillside or a tight zero-lot-line side yard in Echo Park costs more than a flat, open backyard in Northridge, because we’re moving material by hand instead of off a truck tailgate.
What you get at that price, in writing, before any work starts: the full parts list (genuine CGI posts and hardware, OEM or quality aftermarket panels depending on your choice), concrete and post footers if we’re setting new ones, the labor to install and align, haul-away of the failed sections, and our 365-Day Done Right Promise. If a gate sags or a picket pops loose inside that year, we come back and make it right at no charge. That’s a written guarantee on every fence job, and it’s the same promise Trevor Nash built this company on.
We don’t hand you a verbal ballpark and hope for the best. We hand you a written number, with the Kingswell standard behind it: say the price before the work, show up in the window we gave, leave the place cleaner than we found it.
DIY or Call Us?
You can safely check a few things before you pick up the phone. Walk the line and mark every loose picket, every leaning post, every gate hinge that looks off. Snap photos. That information makes our first visit faster and your quote more accurate. Give me the whole picture first, then we pick up the tools.
What we don’t recommend is pulling vinyl pickets or aluminum rails yourself. There’s nothing high-tension here like a garage-door spring, but the interlock tabs on CGI panels are unforgiving. One wrong pry with a screwdriver and you’ll crack the adjacent picket, turning a $40 fix into a $250 section replacement. The posts are another matter entirely: they’re set in concrete, and pulling one without the right method leaves you with a hole that’s too big, a post that wobbles, and a fence that leans in the next rainy season. That’s when the “saved” money disappears. If the post is moving, call us at (936) 259-2607. We’ll give you an honest read over the phone, usually before we even book the visit.
FAQs
A properly installed CGI aluminum fence with powder-coat finish lasts 30 to 40 years in most of Los Angeles, with coastal areas running a bit shorter and inland Valley locations running longer because of the drier air. CGI vinyl systems hold up 20 to 30 years, with UV exposure being the limiting factor. Regular cleaning of the aluminum every spring extends the finish life noticeably. Call (936) 259-2607 if you’re wondering whether your fence is at replacement age or has another decade left.
Yes, and most of the time that’s the smarter move. Individual pickets, hinge assemblies, latch hardware, and even single posts can be replaced without touching the rest of the fence. The exception is when the original installation is failing everywhere at once: multiple leaning posts, widespread picket rot in vinyl, or warped rails. If the labor to patch it starts approaching the cost of a clean install, we’ll tell you that straight, with real numbers. Call (936) 259-2607 and we’ll help you sort repair from replacement.
A typical section replacement where the posts are sound takes one day, including panel alignment and hardware swap. If we’re resetting posts in concrete, it’s two days: day one is pulling the old post, augering and setting the new one, and day two is hanging the panels and gates once the concrete has cured enough to take load. We’ll tell you the timeline before we start, and it’ll be in the written estimate. Call (936) 259-2607 to schedule a visit, and we’ll confirm everything on site before any work begins.
We keep common CGI hinge assemblies, latch hardware, nylon washers, and picket fasteners on the truck, so many small repairs are done same-visit. Full panels and posts are ordered per job because CGI makes several profile variations and we want the match exact. Ordering typically adds two to five business days. If your repair is urgent and the part isn’t on the shelf, we’ll tell you that on the first call, not after we’ve shown up. Call (936) 259-2607 and describe what you’re seeing, and we’ll give you a straight answer on stock before we schedule anything.
