CGI Fence Installation: The Los Angeles Owner’s Guide
CGI fence installation in Los Angeles typically runs $4,130 to $10,620 for a complete fence line, and we carry CGI-compatible components on our trucks for same-week scheduling. Most owners call us after a winter rainstorm strips the finish off a section, or after a car backs into a panel near the alley and bends the top rail beyond repair. The good news is CGI-style corrugated metal fencing is one of the most repairable fence systems on the market, if you’re working with someone who knows the panel profiles and doesn’t try to force a mismatched sheet into your existing run.
What we see most often in Los Angeles yards: the posts are solid, the panels are still structurally sound, but the fasteners have rusted at the lap joints or a gate post has started to lean because the footing wasn’t deep enough when the original fence went in. You don’t always need a full tear-out. Sometimes you need six new panels, a re-hung gate, and a crew that shows up when they said they would.
Which CGI Models This Applies To
CGI (corrugated galvanized iron) fencing in Los Angeles is not one standard product. The most common residential profiles are the 2.5-inch corrugation (often called the “mini” profile) and the 3-inch corrugation. If your fence has a tighter wave pattern, it’s likely the 2.5; wider waves are usually the 3. Panel heights run 4, 5, 6, and 8 feet, with 22-gauge and 24-gauge being the most common thicknesses we encounter in local yards. The gauge matters more than most homeowners expect: a 22-gauge panel resists dents from kids’ bikes and stray basketballs far better than the thinner 24, which some budget installers used on older property-line runs.
Here’s a compatibility gotcha we’ve learned from thousands of Los Angeles fence inspections: CGI panels from different manufacturers come in slightly different corrugation widths, and if you try to lap a mismatched panel into an existing run, the overlap won’t seat flat. Water gets in, rust follows, and you’re replacing it again in three years. We measure the actual corrugation width and gauge on site before ordering anything. As an independent contractor, we’re not affiliated with any CGI panel manufacturer, which means we stock panels and fasteners that match what’s already in your yard rather than steering you toward one brand name.
Styles & brands we work with
Signs Your CGI Fence Installation Is Failing
- Rust bleeding through at the lap joints. Corrugated panels overlap by one full wave, and that’s exactly where moisture sits longest. In Los Angeles coastal neighborhoods like Playa del Rey and San Pedro, marine air accelerates this. Once rust shows at the laps, the protective galvanized coating has thinned to the point where replacement beats painting.
- A gate that drags or won’t latch. The gate post has shifted, usually because the footing was poured too shallow for the soil conditions. In the clay-heavy soil of the San Fernando Valley, winter rains soften the ground and shallow footings lose grip. You can shim hinges for a while, but the real fix is resetting the post.
- Panels bowing between posts. Post spacing on some older CGI fences in Los Angeles ran 8 feet or more, and 24-gauge panels can’t hold that span without sagging. The fix is adding a mid-rail or an intermediate post, and then straightening or replacing the bent panels.
- Fastener heads popping or falling out. The original installer used steel screws without neoprene washers. The steel rusts, the head shears, and the panel starts rattling in wind. We use zinc-aluminum coated fasteners with bonded washers on every CGI replacement.
- Bottom edge erosion. In yards where sprinklers hit the fence line directly, or where soil builds up against the bottom rail, the panel edge degrades long before the rest of the fence. We routinely recommend trimming back soil or redirecting sprinkler heads as part of any repair near a planter bed.

AfterReplacement Cost & What’s Included
For a full CGI fence installation in Los Angeles, the installed price typically falls between $4,130 and $10,620. The range comes down to three things: linear footage, panel gauge (22-gauge runs about 18 to 24 percent more than 24-gauge in material cost), and whether we’re pulling out an old fence line or working with fresh ground. A partial replacement, where we’re matching panels into an existing sound run, usually lands lower: figure $60 to $90 per linear foot installed depending on access and panel height.
Every CGI fence job includes a written line-item price before we start, the removal and haul-away of any old panels we take out, and our 365-Day Done Right Promise in writing. If a post shifts or a panel pulls loose inside the guarantee period, we come back and fix it at no charge. No re-inspection fee, no service call charge. Trevor Nash grew up in the Crenshaw district, and the way he runs this company is simple: give you a number first, then pick up the tools.
DIY or Call Us?
You can safely handle a few things yourself: photograph the full fence line, measure the panel height and count the corrugations across a 12-inch span, and note where the rust or damage starts and stops. That information helps us give you an accurate quote over the phone. What we would not recommend an owner take on: removing full panels and re-hanging a gate. CGI sheets are sharp at the cut edges, a full 6-foot panel weighs 30 to 40 pounds, and a gate post that is leaning needs a much deeper footing than most homeowners realize. If a section is already sagging into a neighbor’s yard or a public walkway, you also want a company that carries liability coverage and knows Los Angeles property-line fence law.
Call us at (213) 277-6578 and we’ll schedule a look at your fence line. The quote is free, it’s in writing, and it won’t change once work starts.
FAQs
A properly installed CGI fence with 22-gauge panels and correctly sealed fasteners lasts 25 to 35 years in most Los Angeles neighborhoods, though the last six feet of a coastal property in the Westside or South Bay may need attention sooner because of salt air. Budget 24-gauge fences with steel fasteners typically show rust and fastener failures by year 10. The exact lifespan comes down to gauge, drainage at the base, and whether the original installer spaced the posts for the panel weight.
If your fence is already on the back half of its lifespan, call (213) 277-6578 and we’ll tell you honestly whether repair or replacement makes more sense.
Yes, in most cases individual CGI panels can be replaced without disturbing the posts or the rest of the run, provided the corrugation profile and gauge match the original fence. The challenge is finding a contractor who will actually measure that profile instead of ordering the first panel that looks close. We match panels on site and replace only the sections that need it. If more than half the panels are compromised, the math usually favors a full replacement.
A typical partial replacement of 20 to 40 linear feet takes one day for two technicians, including haul-away. A full perimeter fence in a Los Angeles yard, with old fence removal and new posts set in concrete, takes two to three days. Gate resetting, if the footing needs to be enlarged, adds about half a day because we let the new concrete set before re-hanging the gate.
We stock common CGI-compatible panels in 2.5-inch and 3-inch corrugation profiles, in 4 through 8 foot heights, along with zinc-aluminum coated fasteners, top rails, and gate hardware on our service vehicles. If your fence needs a non-standard gauge or a custom color, we can source it within a few business days. We also work with materials from brands like KraftMaid, Cambria, and Silestone on our remodeling projects, and we bring the same standard to fence work: real product knowledge, no guesswork on the quote.
