CGI Fence Installation in South Florida, FL

CGI Fence Installation: The South Florida Owner’s Guide

CGI fence installation in South Florida typically runs $3,500-$9,000 for a complete residential system, with most projects completed in 1-3 days depending on linear footage and soil conditions. We stock CGI-compatible posts, rails, pickets, and gate hardware for same-day starts on standard heights. Most homeowners realize their CGI fence needs attention when gate sag becomes visible, coastal corrosion appears at post bases, or panels loosen after a tropical storm passes through.

Which CGI Models This Applies To

CGI manufactures aluminum fencing across several product lines, and the part you need depends on which series was originally installed. The Estate series uses 1-inch square pickets with concealed fasteners, while the Commercial series runs heavier 1.5-inch rails with exposed bracket hardware. Residential-grade CGI systems typically use .065-inch wall thickness for posts; if you’re reading a tape measure and seeing .050-inch, you’re likely looking at a competitor’s knock-off or an earlier CGI economy line that was discontinued in the mid-2010s.

Check the post cap for an embossed CGI logo, or look for a small stamped code on the rail underside that starts with “CGI-” followed by a four-digit year code. We carry both OEM CGI rails and posts from ActiveYards and Jerith that mate cleanly with existing CGI systems when the original profile is backordered, which happens more than you’d think during South Florida’s busy season from October through April.

One compatibility gotcha we’ve run into repeatedly: CGI’s 2018-and-newer gate frames switched from 2-inch to 2.5-inch vertical members. If you’re replacing a gate leaf, measure the frame tube itself, not just the opening. An older gate hung on newer posts will bind, and vice versa.

Signs Your CGI Fence Installation Is Failing

• Gate sag or drag. The aluminum gate frame has twisted at a miter joint, or the post itself has settled in sandy soil common to Pembroke Pines and Weston. CGI gates over 48 inches wide need steel-reinforced frames; if yours was retrofitted without that insert, gravity wins.
• White powder or pitting at post bases. Salt air accelerates galvanic corrosion where aluminum meets concrete. In coastal South Florida neighborhoods like Hollywood Beach or Key Biscayne, we see this inside five years if the installer skipped isolation tape or used standard concrete instead of a sulfate-resistant mix.
• Rails pulling from posts. The internal spline or bracket screw has backed out. CGI’s concealed-fastener system relies on a specific #12 self-tapping screw; generic hardware store replacements strip the aluminum boss after one season of thermal expansion.
• Panel rattle in wind. Picket-to-rail crimp joints have loosened. This is usually a manufacturing-era issue on CGI lots from 2015-2017, when a crimp die wore out of spec. The pickets don’t fall out, but they clatter against every afternoon thunderstorm.
• Gate latch misalignment. Post shift or frame twist throws off the magnetic or gravity latch. In Coral Gables and Pinecrest, where limestone bedrock requires shallow post holes, seasonal ground movement is the culprit more often than the hardware itself.

Replacement Cost & What’s Included

For a full CGI fence replacement in South Florida, budget $3,500-$9,000 installed. A single gate rebuild runs $800-$2,200. Section repairs (one 6-foot panel plus post) typically fall between $650-$1,400.

What moves you up or down: linear footage, access for equipment (tight side yards in Coconut Grove add labor), soil type (rocky Dade County vs. loose Broward sand), and whether we’re matching existing CGI color powder coat or doing full new. Our quotes itemize CGI-compatible materials and labor separately. You choose the brand, we handle the build.

DIY or Call Us?

There’s a safe middle ground here. A homeowner can verify the CGI model code, measure gate opening width to the quarter-inch, and check whether posts are plumb with a 4-foot level. What we don’t recommend: digging post holes near buried utilities, cutting aluminum rail with a saw that isn’t clamped and guarded, or mixing concrete in quantities over three bags without a second person. The posts are light, but the concrete work is where DIY timelines stretch from a Saturday to three weekends.

We carry CGI-compatible posts, rails, and gate hardware on our trucks through South Florida. If you’ve got a tape measure and a photo of the failing section, call (844) 665-0162 and we’ll tell you whether it’s a same-day fix or needs ordering. Do it right the first time or you’ll do it twice - and the second time always costs more.
