CGI Fence Installation: The Jacksonville Owner’s Guide
CGI fence installation in Jacksonville typically runs between $3,500 and $9,000 installed, depending on post condition, panel dimensions, and how much of the old framework we’re salvaging. We stock CGI-compatible fence panels and replacement rails on our trucks, and most swaps are done in a single day. The way owners usually discover a CGI part has failed is the same story every time: a panel that was rattling in the last storm is now leaning hard against the neighbor’s yard, or a gate that used to swing true is dragging a half-moon trench through the St. Augustine grass. CGI’s roll-formed galvanized panels are built to take Florida weather, but the fasteners and rails around them fail first, and once one section lets go, the rest of the run starts working against itself.
Bradford Remodeling Co Jacksonville is an independent service provider. We install and replace CGI fence products, but we are not a CGI factory outlet or corporate installer. What we are is a Jacksonville crew that has pulled enough of these panels apart to know exactly what fails and what it costs to fix it right.
Which CGI Models This Applies To
When we talk about CGI fence installation, we’re talking about CGI’s roll-formed corrugated steel and aluminum panel systems. The panels come in two core profiles: the 2.5-inch corrugated (sometimes called “mini-corrugated”) and the 1.25-inch profile. Both are used across residential and light-commercial fence runs in Jacksonville, but the 2.5-inch panel is the one we see most often on subdivision lots and HOA-governed communities. The panel widths run 26 to 36 inches, and heights from 4 to 8 feet. If your fence stands at 6 feet, you’re most likely working with the 6-foot x 30-inch panel. That matters because the panel width dictates rail spacing, and rail spacing dictates whether your existing rails can be reused or need to be pulled and reset.
Here’s the compatibility gotcha we run into weekly: CGI’s friction-fit panel system relies on the panels seating into C-channel rails. If your fence has screws or rivets driven through the panel face, that’s an aftermarket install, not a factory CGI build. That changes what we can reuse. The other thing to check before you order anything is the gauge. Residential CGI steel panels are 26-gauge. Commercial and high-wind runs are 24-gauge or heavier. Mixing the two on the same rail looks fine for about two seasons, then the lighter panel starts oil-canning against the wind load and pulls the rail out of level. We spec 24-gauge on any Jacksonville run that faces an unbroken wind stretch, which is half the lots east of I-95.
On the OEM-versus-aftermarket question: CGI’s own panels are mill-finish galvanized or pre-painted with a 20-year finish warranty. There are quality aftermarket equivalents that spec the same gauge and corrugation depth, but the paint systems vary widely. The cheap aftermarket panels fade to chalk inside eight years in Florida sun. The factory CGI finish holds color far longer. If the fence is visible from the street, we recommend paying for the real thing. If it’s a backyard enclosure behind a hedge line, a quality aftermarket panel at two-thirds the cost is a defensible call. Either way, the price gets written down before we start. No surprises at the door, because that’s the part of this business we refuse to tolerate.
Styles & brands we work with
Signs Your CGI Fence Installation Is Failing
- Panels rattling in the wind. CGI’s corrugated panels seat into the C-channel rails with a friction fit, and over time the galvanized steel expands and contracts. Once the fit loosens, the panel slaps against the rail in every coastal breeze. Left alone, the same motion works the rail fasteners loose.
- Rust streaking beneath fastener heads. CGI’s panels are galvanized before painting, but a screw that breaks the galvanic layer lets moisture ride straight to the carbon steel underneath. In Jacksonville’s humidity, that becomes a visible rust line within a season, and the fastener loses its bite shortly after.
- Fence leaning away from the wind side. Steel rails rarely bend first. What usually happens is the post-to-rail brackets have corroded or the post itself has shifted in the concrete footer. The panels may be perfectly fine, but the system can’t stand if the connection points are giving up.
- Gate dragging and no longer squaring up. If the gate post has moved even three degrees, the gate leaf sags. That pulls the hinges out of alignment and forces the latch plate to bind. This is a structure problem, not a hardware problem, which means a new hinge set won’t fix it for more than a season.
- Water pooling at the panel base. CGI panels are not designed to sit in standing water. In Jacksonville’s low-lying lots, especially through the San Pablo Creek basin and parts of Arlington, the bottom rail collects silt. That traps moisture against the cut edge of the panel and shortens the life of the bottom four inches.

AfterReplacement Cost & What’s Included
In Jacksonville, a full CGI fence installation on existing posts runs $3,500 to $9,000. A straight panel swap on good posts and rails sits at the low end. The high end is for a full rail replacement, new posts and concrete footers, and a gate rebuild with new hinges and a re-cut latch. The single biggest cost driver is the condition of the posts. If the posts are set in concrete and the concrete is sound, we reuse them and you save real money. If the posts have shifted or the steel is compromised at the base, they come out, and new posts get set the full 30 inches deep that Duval County’s frost and wind load practicalities call for.
Here’s what a written price from us includes: the panels at the spec we agree on, rails to match, brackets and fasteners rated for coastal corrosion, and labor. It also includes the site being cleaned at closeout, not left with cut ends and old fasteners scattered through the grass. The written guarantee is the 365-Day Done Right Promise. If any part of the install fails within one year, Bradford Remodeling returns and corrects it at no charge. You get that in writing before the first tool comes off the truck, and you get a signed copy in your hand at the end.
DIY or Call Us?
What you can safely check yourself: whether the panels are still seated in the rails, whether the fasteners are backing out, and whether the gate post plumb line has moved. You can also check the bottom rail for silt buildup and wash it out with a hose. Those are ten-minute inspections that tell you what you’re dealing with.
What we’d rather you didn’t do is pull panels or reset posts. A steel CGI panel under tension, especially one that’s been binding against a shifted rail, can release sharply once a fastener clears. That’s a pinch or laceration hazard, and post work in sandy Jacksonville soil without a 30-inch footer is how you get a re-lean inside a year. If the fence is leaning, binding, or rusting through at the rails, call us at (904) 337-5929. Scope it right the first time, the job goes a lot smoother when nobody’s surprised.
FAQs
A factory-spec CGI panel on a well-set rail system lasts 20 to 25 years in Jacksonville, but the fasteners and bottom rails typically fail between years 10 and 15. Coastal-adjacent lots east of I-95 see salt-driven corrosion on the hardware first. If the panels are still sound, replacing rails and fasteners buys another decade without pulling the whole fence. Call (904) 337-5929 and we can look at what actually needs replacing before you spend on parts that don’t.
Small creases and cosmetic dents can sometimes be worked back into shape, but any panel with a torn edge, rust-through, or a fastener hole that’s wallowed out should be replaced. Repaired panels lose their friction fit and become noise and wind-load problems later. A straight panel swap is the most cost-effective move, and our truck carries the common CGI sizes so we can quote it accurately on the first visit.
Most single-panel and rail replacement jobs finish in one working day. A full-fence CGI installation with new posts and a gate rebuild runs two to three days depending on how much concrete work is involved and how many post holes are fighting us. We’ll give you a written timeline with the written price, so the finish date is part of the agreement, not a guess.
Our trucks carry the most common CGI panel sizes, rails, brackets, and corrosion-rated fasteners. If your run needs a specific gauge, color, or height outside the standard inventory, we order it from our supplier and schedule the install when it lands, usually within a week. Either way, the quote you get is the price you pay, nothing moves at the door. Call (904) 337-5929 for a free estimate.
