CGI Windows & Doors in Miami Beach, FL

CGI Windows & Doors in Miami Beach, FL | Winslow Windows & Doors

We provide independent Impact Windows in Miami Beach service, from South Beach Art Deco walk-ups to Collins Avenue high-rises. What makes our CGI work different here is simple: we know which retrofit details pass both the Miami-Dade HVHZ inspector and the Historic Preservation Board on the same permit. That dual-logic knowledge matters more on Miami Beach than anywhere else in Florida. Ed Winslow has spent over a decade doing CGI installs and repairs on this barrier island, and we carry the specialty parts that salt air destroys faster than homeowners expect.

Why Miami Beach Residents Choose Us for CGI Service

We’re not a CGI authorized shop. We’re independent, which means we answer to you, not a manufacturer’s warranty calendar. Our techs have reverse-engineered CGI’s aluminum frame joinery and hardware across hundreds of Miami Beach installs. We document real-world CGI corrosion patterns and retrofit outcomes in salt air, the kind of data factory literature never covers.

Ed Winslow grew up in Hialeah’s Westland area, patching windows on older concrete-block homes with his uncle. He learned building science at Miami Dade College’s Wolfson Campus before spending years doing installs across South Florida’s worst weather. His name’s on the truck and on the warranty, and that’s not something he takes lightly. When you call about a CGI window in Miami Beach, the person making decisions has actually pulled these frames apart here, in this salt, on these buildings.

Common CGI Windows & Doors Problems We Solve in Miami Beach

Here’s what we see on CGI product in Miami Beach, and why it happens faster here than inland:

• Galvanic corrosion at weep hole inserts and sill track screws. CGI’s stainless hardware meets raw aluminum at the weep holes and sill track. On Miami Beach, ocean salt saturates those joints and accelerates the reaction. We see it in as little as four years on Collins Avenue elevations. We replace the fasteners with 316-stainless and the weep baffles with marine-grade units.
• Roller cartridge bearings seizing in CGI 3-lite sliders. The Classic Sliding Glass Door uses roller cartridges that crust up badly in salt air. On ocean-view condos, we’ve pulled sliders where the bearing seized entirely, causing panel derailment. Salt from the Atlantic works into the roller housing and hardens.
• Deteriorating EPDM glazing gaskets shrinking under UV plus salt. Miami Beach’s combination of relentless sun and airborne chlorides shrinks EPDM faster than either factor alone. The air seal breaks, and you get whistling around fixed lites. We replace with marine-grade gaskets that outlast the factory material.
• Bowed vertical stiles on 60-inch-wide CGI Estate casements. After repeated HVHZ wind cycling, wide Estate casement frames can bow just enough to prevent the multi-point lock from fully compressing. This is a Miami Beach problem because the barrier island catches wind from both the Atlantic and Biscayne Bay.
• Corroded corner keys and pitted anodizing. Miami Beach salt eventually eats through the anodized finish at frame joints. Once the corner key is compromised, rebuilding usually costs more than replacement, especially in condos where scaffolding is already scheduled for the building’s milestone inspection work.

CGI Service in Miami Beach: What Local Conditions Mean for Your Equipment

Here’s something most window companies won’t tell you until after you’ve ordered: a CGI window with a valid Miami-Dade Notice of Acceptance can still be rejected by the Historic Preservation Board if the frame depth or sightline doesn’t replicate the original 1930s steel casement look. That’s not a Broward problem. That’s not a Palm Beach problem. That’s a Miami Beach Art Deco District problem, and it exists nowhere else in South Florida. We stock a narrow tier of CGI Estate models with slim stiles and custom paint that satisfies both the HVHZ inspector and the preservation officer on the same permit.

On Ocean Drive, our crew pulled two seized CGI Targa double hungs from a 1939 Art Deco low-rise after salt crusted the balance springs and rotted the sill track. We replaced the balances with marine-grade 316 stainless assemblies, swapped in OEM weep baffles, and reinstalled the sashes with fresh EPDM gaskets. The building’s 50-year recertification passed without triggering Historic Preservation Board review because we kept the original thin frame profile.

CGI Models & Products We Service in Miami Beach

We service the full CGI lineup sold in the HVHZ market. That includes the CGI Estate Collection casements and awnings, the CGI Targa Series double hungs and single hungs, the CGI Classic Sliding Glass Door with its 3-lite roller system, and the CGI Sentry Impact French Door. We prefer OEM CGI rollers, lock keepers, and weep baffles when lead time allows, but for salt resistance we’ll use 316-stainless aftermarket fasteners and marine-grade gaskets from Miami-Dade suppliers. We stock the fast-moving parts locally so Miami Beach turnaround doesn’t wait on a ground shipment.

FAQs - CGI Windows & Doors in Miami Beach

Will a CGI Estate casement with a Miami-Dade NOA pass the Historic Preservation Board on an Art Deco building?

Only if the frame depth and sightline match the original thin-profile steel casement look. We stock slim-stile Estate models with custom paint specifically for that dual approval path. Your best move is to call (850) 998-3090 before ordering anything, because we can tell you from photos whether the model you’re considering will clear the preservation officer.

Can you replace just the rollers in a CGI 3-lite slider that binds from salt corrosion on Collins Avenue?

Yes, if the roller cartridge housing itself hasn’t corroded through. The cartridge is the sacrificial part. If the housing and track are intact, we swap in OEM rollers and you get another several years. If the track’s pitted, the repair calculation changes. Call (850) 998-3090 and we’ll assess it on site. Estimates are free.

What’s the difference between CGIs sold in Miami Beach vs. Fort Lauderdale for high-rises?

The product is the same. The difference is who’s allowed to touch it and what fasteners they’re using. Miami Beach sits in the HVHZ, which means every CGI product must carry a Miami-Dade NOA. Fort Lauderdale doesn’t have that exact requirement. We stock Miami-Dade-compliant parts and the 316-stainless hardware that survives barrier island salt.

How does the city’s road-raising program affect our ground-floor CGI door replacement?

Finished grades on several Miami Beach blocks have changed after the city elevated streets for tidal flooding. That shifts sill heights and threshold clearances on ground-floor doors. We check grade first, then spec the replacement so it drains correctly. Call (850) 998-3090 and we’ll look at it before any ordering happens.

Do we need an HOA approval to replace CGI windows in a Mid-Beach condo over 30 stories?

Yes. Condos in that height range almost always require board approval and unit-by-unit permitting, especially post-Surfside. We handle the paperwork and coordinate with the board’s scaffolding schedule. If your tower is already scheduling milestone inspection work, that’s often the cheapest time to replace windows. Call (850) 998-3090 to talk through your building’s specific situation.
