CGI Fence Installation: The Miami Owner’s Guide
CGI fence installation in Miami typically runs $4,130 to $10,620 installed, depending on fence line length, the condition of your existing posts, and whether we’re swapping panels only or pulling and resetting posts. Most CGI fence repairs are completed in one to two days once we have your measurements confirmed. Homeowners usually discover they need this work after a storm lifts a panel, a gate stops latching, or a section of fence starts leaning toward the neighbor’s yard about six years into its life.
We’re Penhallow Remodeling Miami, led by Trevor Nash. We’re an independent general contractor that works with CGI-compatible fencing, and we’re not affiliated with CGI itself. If you’ve got CGI fencing around a Coconut Grove home or anywhere else in Miami and a section has given up, this page tells you exactly what you’re looking at for cost, what we replace, and what’s worth saving.
Which CGI Models This Applies To

CGI’s residential fence lines here in Miami split into two broad families: the CGI Classic (their older, thinner-gauge aluminum panels with a straightforward vertical picket profile) and the CGI Estate series, which uses a heavier extrusion and a wider top rail. Parts between the two don’t always swap cleanly. The Estate rail is about an inch deeper than the Classic, so a replacement panel made for Classic won’t seat correctly in an Estate post channel without modification. That’s a compatibility gotcha we check before ordering anything.
How to identify what you have: look at the post caps. Classic posts have a flat, slip-on cap; Estate posts use a flared cap that overhangs the post by roughly a quarter-inch on all four sides. If the caps are missing, measure the post channel width. Estate posts run about 2 3/8 inches; Classic posts run 2 inches flat. If we’re replacing just a single panel or section, we match the original thickness so the repaired run doesn’t ripple in the light differently from the rest. We also stock a quality aftermarket equivalent for both lines where OEM panels are backordered. In our experience, the aftermarket extrusion holds up comparably in Miami’s salt air, and it costs about 20% less. We’ll show you both options with real numbers before anything gets ordered.
Styles & brands we work with







Signs Your CGI Fence Installation Is Failing
- Leaning posts with solid panels: The panel itself is usually fine. What’s failing is the post footing: Miami’s sandy soil lets water undermine concrete around the post base, especially after heavy summer rain. The post tilts, and the panel rides along with it.
- Panel rattling in wind: The rail-to-post bracket hardware has corroded. Salt air from Biscayne Bay accelerates this. Once the mounting screws lose their bite, the panel clatters against the post with every gust.
- Gate dragging or not latching: The gate hinge posts have shifted (same footing issue as above) or the hinge hardware itself has wallowed out. A dragging gate in Miami is almost always a post problem, not a hinge problem.
- White chalky powder at joints: That’s galvanic corrosion where the aluminum panel meets a steel mounting clip or screw. It starts as a cosmetic problem and becomes a structural one when the joint weakens.
- Buckled or bowed bottom rails: This is from impact, usually a mower or a misplaced ladder, but also from wind-driven debris. A bowed bottom rail stresses the pickets above it and eventually splits the panel at the corners.

AfterReplacement Cost & What’s Included

In Miami, CGI fence installation runs $4,130 to $10,620 for a full residential fence line replacement. Where you land inside that range depends on linear footage, whether we can reuse existing posts in good condition, and whether you’re on the Classic or Estate line, since Estate panels and rails cost more. Partial repairs, like replacing three or four panels with new hardware and resetting one post, typically land between $1,800 and $4,000.
Every quote we give has two line items: the parts and the labor, listed separately. You see the panel cost, the post cost, the hardware cost, and what we charge to install each section. That number is on paper before any work starts, and it does not change at the door. The workmanship warranty is covered under our 365-Day Done Right Promise: if the fence section fails inside a year, we return and fix it at no charge. That’s written into the contract, not a verbal wink.
DIY or Call Us?
There’s a reasonable amount an owner can check. You can identify your panel series using the post cap method above. You can photograph the rail end and the post channel so we know what we’re pricing. You can tell whether the soil around a post is actually soft or just dark from rain. That’s all useful when you call.
What we’d tell you not to do is pull posts and reset them yourself. A 7-foot aluminum fence panel acts like a sail in Miami wind. Removing it without bracing the adjacent section can fold the entire run. And resetting a post means digging 30 inches into soil that sometimes contains old irrigation lines. We’ve seen homeowners hit a sprinkler main with a post digger and turn a $400 post reset into a $2,000 landscape repair. If a section is leaning or a panel is loose, call us at (850) 988-7559. Trevor Nash has been in this trade since he learned it at Los Angeles Trade-Technical College, and the crew knows Miami soil. Give you a number first, then pick up the tools.
FAQs

Expect 15 to 20 years from CGI aluminum fencing in Miami, though hardware like brackets and screws typically needs replacing somewhere around year 8 to 10 because of salt air corrosion. The panels themselves usually outlive the hardware and the post footings. Call (850) 988-7559 for an exact assessment of your run.
Yes, if the panel extrusion is not split and the post has not shifted, we can replace the hardware, straighten the rails, and reset the section for significantly less than full replacement. The decision comes down to whether the aluminum itself is compromised. Estimates are free.
A full residential fence line in Miami takes one to two working days once parts are on site. Partial panel replacement with hardware takes half a day. If posts need resetting, concrete cure time adds a day before we hang the panels. Call (850) 988-7559 for a timeline on your specific job.
We stock common CGI-compatible panels, rails, brackets, and post caps for both the Classic and Estate lines at our Miami locations, so most repairs don’t wait on a distributor. If your exact panel has been discontinued, we’ll show you the aftermarket equivalent with the price difference before ordering.
