AfterCGI Windows & Doors in Miami Beach, FL | Winslow Windows & Doors
We provide independent Cgi specialists window and door service across Miami Beach, from South Beach Art Deco buildings to mid-Beach and North Beach condos. The one thing that makes our CGI work different here: we understand what salt spray, HVHZ code enforcement, and the Historic Preservation Board do to these windows over time. Ed Winslow founded Winslow Windows & Doors in 2011, and our team works on CGI equipment in Miami Beach every week. If you need a repair, replacement, or honest assessment, call us at (727) 291-4678. We’re independent, which means we’ll tell you the truth about whether a fix makes sense or a full replacement is the only way to stay code-compliant.
Why Miami Beach Residents Choose Us for CGI Service
Most homeowners don’t realize how many CGI windows in Miami Beach have been running on borrowed time for years. We regularly see 1990s and early 2000s CGI frames that have never had proper marine-grade maintenance, and the salt air here punishes them harder than almost anywhere else in the state. Our technicians work on the full CGI lineup, from Sentinel Series Impact Windows in Miami Beach to Estate Series single hungs, and we use OEM CGI hardware and seals whenever the factory still supplies them. That’s the distinction that keeps your window performing like it should instead of fitting “close enough.”
Ed Winslow grew up in Little Gables, not far from the old Coral Gables Congregational Church, and he still lives within a few miles of where he learned to ride a bike. He learned the trade at Miami Dade College’s Kendall Campus building construction program before ever setting foot on a job site. That foundation shows in how we approach every Miami Beach repair: measure twice, explain what you’re actually paying for, and don’t leave until the window closes like it’s supposed to. Call us, and a live person answers. No voicemail loops.
Common CGI Windows & Doors Problems We Solve in Miami Beach
- Aluminum frame pitting and white oxidation blooms along the bottom rail. This is the most common salt-spray failure we see on older CGI frames that didn’t come with factory-applied marine finishes. Miami Beach’s barrier island location means frames here corrode faster than identical units installed in Coral Gables or Kendall. We can often clean and seal early pitting, but advanced corrosion means a sash or frame replacement conversation.
- Weep-hole clogging with sand and salt scale on horizontal sliders. CGI 900 Series horizontal roller windows are everywhere in mid-Beach and North Beach condos, and their weep holes love to clog with wind-blown sand and crystallized salt. When water can’t drain, it backs up into the track and corrodes the internal rollers. We clear the weep system, replace damaged rollers with OEM parts, and show you how to keep the channels clear.
- Compression weatherstrip flattening on casement and single hung sashes. That rubber bulb loses its “return memory” after years of thermal cycling in Miami Beach heat. Once it flattens, air leaks start showing up in energy audits and your AC works harder. We replace it with the correct OEM profile, not a generic strip that doesn’t seat properly in the CGI channel.
- Glass-to-frame silicone beads shrinking and separating. South- and east-facing elevations in Miami Beach take direct wind-driven rain, and repeated expansion and contraction eventually breaks the silicone bond. Water wicks into the jamb and starts causing hidden damage. We cut out the failed bead, clean the channel, and rebed the glass correctly.
- Sticky sashes and hard-to-operate windows. If you’re fighting your CGI window to open or close it, something’s wrong. Often it’s accumulated salt scale in the track, sometimes it’s a worn roller or balance system. Either way, forcing it makes the problem worse. We diagnose the actual cause instead of lubricating over it and leaving.
CGI Service in Miami Beach: What Local Conditions Mean for Your Equipment
Miami Beach is not like the rest of Florida when it comes to windows, and the thing nobody explains is the dual-compliance gauntlet. This is the only municipality in the country where a fully HVHZ-approved CGI impact window can still be denied by the Historic Preservation Board on an Art Deco District building purely because the replacement frame profile is deeper or the meeting rail is wider than the original steel casement lines. Miami-Dade County’s HVHZ Notice of Acceptance requirements are the strictest impact-ratings in the nation, and clearing them is hard enough. But on a Collins Avenue building or over on Euclid Avenue in South Beach, you’re also answering to a design review board that cares about sightlines and facade character. A window that satisfies every structural and wind-load test can still get rejected because it doesn’t look right. That’s a frustration unique to Miami Beach, and it means you need a contractor who can talk through both sides before you order a single frame.
CGI Models & Products We Service in Miami Beach
Our techs service the CGI Sentinel Series impact windows, the CGI 900 Series horizontal roller windows, CGI Estate Series single hung windows, and CGI Classic Series casement windows. Many of these were installed in Miami Beach during the post-Andrew retrofit boom, which means we’re now seeing the same models at the same age failing in the same ways across whole buildings. For parts, we use OEM CGI hardware and seal parts when they’re still available, because aftermarket rollers and locking strips rarely match the original track profiles. When the factory has discontinued parts for an older CGI line, especially in an HVHZ zone like Miami Beach, we’ll be straight with you: a patched older window won’t meet current NOA requirements, and a full frame replacement is the only path that keeps you legal. We also handle Miami Beach Window Installation, full frame replacement, energy-efficient upgrades, and hurricane impact window installs.
CGI Service Pricing in Miami Beach
CGI window repair in Miami Beach typically costs between $180 and $340 per window, depending on what’s actually wrong. Simple weatherstrip replacement and weep-hole clearing sit at the lower end. A full roller replacement on a 900 Series horizontal slider runs toward the higher end, and full frame replacement is a different kind of project entirely, usually $1,800 to $4,000 per opening. What drives the cost: whether OEM parts are still available, whether the frame has advanced salt pitting, and whether you’re in the HVHZ zone (which in Miami Beach, you always are). A free estimate from us includes the diagnosis, the line-item price, and a straight answer about whether repair beats replacement. Call (727) 291-4678 for an exact quote.

FAQs - CGI Windows & Doors in Miami Beach
Why did my CGI impact window pass a Miami Beach permit inspection years ago but the current frame is pitting and the sash is hard to open?
Because inspections confirm the window meets code at install, not that it’ll hold up to fifteen years of salt spray on a barrier island. Pitting and sticky operation develop over time, especially on pre-2000 CGI frames that didn’t ship with upgraded marine finishes. Repairable if caught early.
Can you replace just the glass in my old CGI casement window, or does the whole frame have to come out in Miami Beach?
If the frame is still structurally sound and HVHZ-compliant, yes, we can reglaze with the correct impact glass and keep the frame. But if the frame has deep pitting or the weatherstrip channels have corroded beyond a good seal, you’re in full replacement territory. We’ll tell you which path applies to your window before any work starts.
Why did the Miami Beach Historic Preservation Board reject my proposed CGI impact window even though it has a Miami-Dade NOA?
Because an NOA proves structural and wind-load performance, not aesthetic compatibility. Miami Beach’s Art Deco Historic District has design review standards that regulate frame depth, meeting rail width, and sightlines. A fully approved CGI window can still fail design review if its profile changes the facade character. Call (727) 291-4678 and we’ll walk you through what’ll pass on your specific building.
What is the easiest way to tell if an older CGI window in Miami Beach can be repaired instead of replaced?
Look at the bottom rail. If you see white oxidation blooms but the aluminum isn’t deeply crumbled, there’s a good chance of repair. If you can push a fingernail into soft, flaking metal, the frame integrity’s gone. We’ll give you an honest read either way.
Why do neighbors in a mid-Beach condo get a different CGI window solution than the same building on South Beach?
South Beach buildings fall under the Historic Preservation Board’s design review, which can restrict frame profiles and finishes even when the window is fully approved under HVHZ code. Mid-Beach buildings are typically 1950s-1970s concrete-block construction without that design layer. Same CGI product line, different approval path. Call (727) 291-4678 to sort out which applies to you.

Our crew pulled a 1998 CGI Sentinel single hung from a 1939 building on Euclid Avenue in South Beach after the owner showed us salt pitting along the lower frame and a sticky sash. The inner track was clogged with compacted salt and the original compression bulb was flat, so we cleaned the frame, replaced the weatherstrip with the OEM profile, and reinstalled the sash with the original NOA label intact. That window got another decade of HVHZ compliance without a full replacement. Your window might be in the same shape, or it might need more. Either way, call (727) 291-4678 for a free estimate. Ed’s name is on the truck, so the work has to be right – every time. The one down the road.
