CGI Fence Installation Nationwide

CGI Fence Installation: The Miami Owner’s Guide

CGI fence installation in Miami typically runs $4,130-$10,620 for a standard residential vinyl or aluminum fence system, with most jobs quoted and scheduled within 48 hours. We stock CGI-compatible posts, rails, pickets, and gate hardware for same-day replacement of failed sections, and we carry the full line of CGI’s Signature and Estate series components on our trucks. Most homeowners discover a problem when a gate sags and won’t latch, a post leans after a storm, or a rail pops out of its bracket during normal use.

Which CGI Models This Applies To

CGI, or Custom Gate & Iron, manufactures two primary fence lines we work with in Miami: the Signature series (aluminum ornamental fencing) and the Estate series (heavy-gauge aluminum with reinforced rails). The Signature line uses 5/8-inch square pickets with 1-inch top and bottom rails; the Estate line steps up to 3/4-inch pickets and 1.5-inch rails with internal reinforcements. You can identify your series by the stamped label on the inside face of the end post, usually 6 inches above ground level, or by measuring the picket width with a tape measure.

The OEM-versus-aftermarket question for CGI is straightforward: for posts and gate frames, we use genuine CGI components because the wall thickness and rail-slot spacing are proprietary. For pickets and standard brackets, we stock Miami-tested equivalents from Ameristar and Jerith that match the gauge and powder-coat spec at a lower unit cost. The compatibility gotcha is the Estate series gate hinge pin, which is 7/16-inch diameter; standard 3/8-inch aftermarket pins will wallow out the bracket in six months of Miami’s salt-air cycle. We learned that on a job in Coral Gables where the customer supplied their own hinges, and we replaced them under our 365-Day Done Right Promise at no charge.

Signs Your CGI Fence Installation Is Failing

• Gate sag and latch misalignment. The top rail-to-post connection loosens as the aluminum expands and contracts through Miami’s wet-dry cycles. The gate frame goes out of square, and the latch bolt no longer meets the striker plate. This usually starts at the hinge-side post, which takes the torsion load every time the gate opens.
• Rail pop-out from bracket. CGI’s snap-lock brackets can fatigue after 8-12 years in South Florida’s UV exposure. The rail end pulls free, often after a kid climbs the fence or a lawn crew bumps it with equipment. The bracket itself looks intact, but the internal spring tab has lost tension.
• Post lean or rotation. The concrete footing cracks or the post base corrodes where the aluminum meets the soil. In Miami’s sandy loam, a 36-inch depth is standard, but we regularly find original installs at 24 inches that fail during our fall storm season. The post tilts toward the gate side because that’s where the dynamic load concentrates.
• Picket fade or chalking. CGI’s powder coat is rated for 3,000 hours salt-spray, but Miami’s coastal exposure exceeds that near the water. The Kynar finish chalks white and the underlying aluminum oxidizes. This is cosmetic until the metal thins enough that the picket bends under hand pressure.
• Gate wheel or closer failure. The self-closing hinge spring loses tension, or the gate wheel seizes from sand and salt intrusion. The gate drags, the motor strains if it’s automated, and the bottom rail takes impact damage from repeated ground contact.

Replacement Cost & What’s Included

CGI fence installation in Miami falls between $4,130 and $10,620 depending on linear footage, soil conditions, and whether we’re replacing failed components or installing new. A typical 150-foot Signature series install with one walk gate runs toward the lower end; an Estate series install with a double driveway gate and automation prep pushes the upper range. Here’s how the pricing breaks:

Every quote is a flat written price with line-item scope, delivered before work starts. Under Clause 1 of The Haven Standard, that number does not change unless you sign a change order. Our 365-Day Done Right Promise covers the installation workmanship, and CGI’s 20-year limited warranty covers the aluminum structure against manufacturing defects.

DIY or Call Us?

There is no high-tension danger in aluminum fence work, but there are two places where DIY goes wrong and costs more than the original repair. First, post setting: Miami’s water table is high, and a post hole that fills with groundwater will float the concrete footing if you don’t know how to stage the pour. We’ve pulled out DIY posts that were plumb at noon and leaning 4 degrees by sundown. Second, gate alignment: a sagging gate is almost never fixed by tightening one hinge. The frame is out of square, and shimming without a long level just masks the problem until the latch fails completely.

What you can safely check: verify the stamped model on the post, measure the picket width, and photograph the bracket type. That information lets us bring the right components on the first trip.
