CGI Windows & Doors in Miami Beach, FL | Winslow Windows & Doors
We’re an independent CGI service provider offering Impact Windows in Miami Beach and doors, and we handle everything from seized rollers on high-rise horizontal sliders to full frame replacements in Art Deco buildings. The difference here is salt air plus historic preservation rules. Nobody else on this barrier island combines CGI-specific parts knowledge with the dual NOA-plus-Historic Preservation Board paperwork this city demands. Call (239) 310-4121 and a live person picks up.
Why Miami Beach Residents Choose Us for CGI Service
Our techs have pulled apart enough CGI Estate Collection casements on Euclid Avenue and Collins Avenue to know exactly which hinge arms freeze first and which factory finishes fail two blocks off the ocean. Ed Winslow grew up in Miami Springs and learned the trade through Miami-Dade College’s Building Construction Technology program, then spent years watching South Florida humidity, salt air, and hurricane season punish bad Miami Beach Window Installation jobs. That hands-on experience matters when a CGI window is leaking air and a 40-year recertification is looming.
We’re not a CGI factory warranty center. We’re better positioned for Miami Beach specifically, because we make repair-versus-replace calls based on what actually survives this island’s conditions, not what a manufacturer’s flowchart says. OEM parts when they’re available and NOA-compliant. Marine-grade aftermarket equivalents when a model line is discontinued. Straight answers either way.
Common CGI Windows & Doors Problems We Solve in Miami Beach
- Salt-air pitting and corrosion on CGI aluminum frames and stainless steel hinges. Within two blocks of the Atlantic or Biscayne Bay, factory finishes fail measurably faster than inland. We see hinge arms frozen solid on Estate Collection casements in mid-century condo buildings near the beach, and pitted frame corners where the anodizing thinned first.
- Roller wheel wear and track debris buildup on CGI horizontal roller models. High-rise condos along Collins and West Avenue get constant wind-driven sand and salt. Panels get sticky, then derail. Track cleaning helps temporarily, but worn rollers need replacement before they gouge the aluminum.
- Seal and gasket degradation on older CGI impact windows. Once gaskets crack from UV and salt exposure, the window loses design pressure rating, which is the exact thing Miami-Dade County inspections check. Air leaks are the first sign. During HVHZ inspection cycles or 40-year recertifications, these failures become expensive surprises.
- Hardware and multi-point lock misalignment on CGI French doors. Mid-century concrete-block condo buildings on Miami Beach settle constantly. Door slabs shift, locks bind, and eventually the door won’t seal or latch properly. We adjust or replace hardware before the interlock fails outright.
- Jalousie-to-impact conversions in 1950s and 1960s walk-up apartments. These buildings are everywhere in South Beach, and the original louvered glass provides zero hurricane protection. Converting to CGI impact windows means keeping rough openings identical to avoid Historic Preservation Board review, or filing a two-agency permit if they change.
CGI Service in Miami Beach: What Local Conditions Mean for Your Equipment
Miami Beach is the only place in the region where every window and door replacement must satisfy two masters at once. Miami-Dade County NOA compliance is mandatory island-wide, but in the South Beach historic district, the Miami Beach Historic Preservation Board also reviews any alteration that changes a building’s original fenestration profile. That means a 1920s Mediterranean Revival building or a 1940s Art Deco walk-up can’t just get a modern CGI 800 Series window slapped in. The rough opening, the sightlines, the divided-light pattern: all of it has to stay visually faithful to the original. If the opening size changes at all, the HPB must approve it before the job moves forward. We plan every historic-district CGI job around both agencies from day one, because a permit that stalls at the HPB stage adds weeks to a project that looked routine from the street.
This is not a problem in Miami Springs, Doral, or Hialeah. It’s a Miami Beach problem, and it shapes which CGI product we recommend, how we order the glass, and how we schedule the work. Our experience on this island means we know which buildings will trigger HPB review and which won’t, and we tell owners before they spend a dollar.
CGI Models & Products We Service in Miami Beach
We work on the full CGI product range across Miami Beach, including the Estate Collection impact windows (casement, single-hung, picture), Classic Collection horizontal roller windows, 800 Series aluminum impact windows, and Estate Collection French doors and sliding glass doors. For impact-rated glass, rollers, and locking mechanisms, we source OEM CGI parts because Miami-Dade NOA compliance ties to factory specifications. When hardware is discontinued or cosmetic components are no longer made, we use marine-grade aftermarket equivalents. If frame corrosion has compromised the structural interlock, we recommend full replacement and tell you why. For full brand details, see our CGI sales & service page.
We stock common rollers, gaskets, and stainless hardware locally so most Miami Beach service calls don’t wait on a parts shipment from the manufacturer.

FAQs - CGI Windows & Doors in Miami Beach
Yes, if the existing frame is structurally sound and the rough opening hasn’t been compromised by corrosion. We re-glaze with NOA-rated impact glass and OEM-compatible glazing beads, which preserves the original frame and often avoids Historic Preservation Board review. If the frame shows pitting deep enough to affect the interlock, we’ll tell you a full replacement is the better call. Call (239) 310-4121 and we’ll inspect it.
Only if the rough opening size or visible profile changes. Keeping the original fenestration exactly as built means the job usually clears the Building Department on the NOA alone. Change the opening or the sightlines, and the HPB gets involved, which adds review time. We’ve done both types of jobs across Miami Beach and we’ll tell you which path your building falls into before you commit.
Because the roller wheels are wearing flat, and salt air accelerates it. Cleaning the tracks removes debris but can’t restore worn wheel bearings. On Miami Beach, especially in high-rise condos near the ocean, sand and salt grind the rollers down faster than inland. Once the wheels flatten, they gouge the track and the panel derails. Replacement rollers are an OEM part and the fix usually takes under an hour per panel. Call (239) 310-4121 for a quote.
Yes. Miami-Dade County requires NOA compliance for every window and door product installed in Miami Beach, regardless of what’s already on the building. A condo having impact glass elsewhere doesn’t exempt a new door from its own NOA. We pull the permits and coordinate with your building’s management on access and scheduling. Free estimate: (239) 310-4121.
Gasket and seal degradation from UV and salt exposure. The rubber dries, cracks, and loses compression, which lets air through and drops the window’s design pressure rating. That’s a critical item during HVHZ inspections and 40-year recertifications. We replace gaskets with OEM or equivalent marine-grade material and verify the seal with a pressure test. Call (239) 310-4121 to schedule an inspection.
