CGI Windows & Doors in Miami, FL | Winslow Windows & Doors
We service and repair Impact Windows in Miami and doors across the city, from Kendall’s CBS ranches to the Brickell high-rises. Winslow Windows & Doors is an independent CGI service provider, not a manufacturer affiliate, so we call repairs the way they are: fix what’s salvageable, replace what won’t survive another Miami hurricane season. The one thing that makes our CGI work different here is the Miami-Dade Notice of Acceptance (NOA) requirement: every opening we touch must carry the right sticker and paperwork, or the inspection fails and insurance won’t write the policy. Call (727) 620-6983 to get straight answers and a free estimate.
Why Miami Residents Choose Us for CGI Service
We’ve been working on CGI’s aging storm-rated stock in Miami for long enough to know its failure patterns before we pull the sash. Blown IGUs in Series 300 single-hungs, seized Classic-Pro slider rollers in salt-air corridors along Biscayne Boulevard, Targa weatherstripping that’s given up after a decade of UV: these are the calls we run every week. Because we’re independent, we’re not tied to CGI dealer lead times or a manufacturer’s warranty matrix. We stock OEM-equivalent structural components for interlock channels, corner keys, and roller sets locally, so a repair doesn’t stall waiting on a truck from Georgia. Ed Winslow, our owner, learned the trade through Miami Dade College’s Building Construction Technology program and spent years in the field before putting his own name on a truck. He’s the guy Fountainebleau homeowners call when hurricane season is closing in and they want a straight answer about what their house actually needs. My name’s on the door, literally. That means I answer for every job we do.
Common CGI Windows & Doors Problems We Solve in Miami
- Blown IGUs in Series 300 sashes: The desiccant inside the insulated glass unit can’t keep up with Miami’s humidity swings. Fogging starts in the lower corners and spreads within 10 to 15 years. We replace the IGU and reseal the sash, and if the frame’s still square, that’s all it needs.
- Bowed or seized Classic-Pro slider tracks: In Brickell and along Biscayne Boulevard, salt air eats roller assemblies far faster than inland Miami. A slider that drags or locks up usually needs new rollers and a track cleanup, not a whole door. We’ll tell you which one before we start.
- Weatherstripping compression set on Targa casements: Daily UV exposure hardens and flattens the seals, so panels whistle during thunderstorm downdrafts even when the locking points still align. New marine-grade weatherstripping stops the leak and the noise.
- Fractured corner keys in 1990s-era CGI frames: We see this on old jalousie-to-impact conversions where the original aluminum buck was reused instead of replaced after the 2001 Florida Building Code. A fractured corner key compromises the entire frame’s rack resistance. We replace the corner keys and, when the extrusion’s too wallowed out, recommend a full-sash swap.
- Failed interlock channels: The vertical channel where two impact sashes meet takes enormous wind load during a Miami storm. Corroded or bent interlocks reduce the window’s pressure rating and can fail inspection. We stock OEM-equivalent interlock channel sections for CGI frames.
CGI Service in Miami: What Local Conditions Mean for Your Equipment
Miami-Dade County sits inside Florida’s High-Velocity Hurricane Zone, the strictest window-and-door jurisdiction in the country. Every replacement opening must carry a Miami-Dade Notice of Acceptance, a certification tier many nationally sold brands never bother to obtain. What this means for a CGI owner in Miami specifically: if your window or door was installed before the current code cycle, or if someone converted a jalousie opening without pulling permits and applying the NOA sticker, Citizens Insurance can deny or drop coverage after a claim. That’s not a scare tactic; it’s the underwriting rule. Homes in Hialeah, Kendall, West Miami, and Little Havana still carry original jalousie windows that are flatly illegal for replacement use under county ordinance. When a jalousie sits next to a CGI Series 300 installed a few years back, as we see often in Hialeah, the entire opening becomes a compliance problem, not just an upgrade question. We handle the permit, the conversion, the sticker, and the inspection, because a CGI window without the NOA paperwork simply won’t survive scrutiny by the city or an insurance adjuster. Full transparency: we’re an independent service provider, not manufacturer-affiliated. That’s what lets us be blunt about when a repair makes sense and when the frame is done.
CGI Models & Products We Service in Miami
We service the full CGI lineup you’ll find across Miami, including Series 300 Single-Hung Impact Windows, Classic-Pro Sliding Glass Doors, Estate Collection Windows, and Targa by CGI Impact Windows. When we repair, we use OEM-equivalent structural components for interlock channels, corner keys, and roller sets, stocked locally so we’re not holding up a Miami repair waiting on manufacturer freight. When we replace, it’s because the extrusion is bent or corroded past the point where new hardware would hold, not because we’d rather sell a window than fix one. We’re honest about the difference. Our CGI sales & service team knows these frames from the inside out, and being independent means the recommendation you get is based on your house, not a dealer quota.
CGI Service Pricing in Miami
CGI service pricing in Miami runs from roughly $150 for a simple roller or weatherstripping repair up to $900 or more for a full sash rebuild with new insulated glass and corner keys. Full jalousie-to-impact conversions with permits and NOA stickers start around $1,200 per opening and climb based on frame condition, opening size, and stucco or flashing work around the buck. What drives the cost here more than anything is whether someone reused the original aluminum buck on an old conversion; fixing that properly takes time and materials. Every free estimate we give is line-itemed, written, and honored. No trip charge inside the county. Call (727) 620-6983 and we’ll tell you exactly what yours needs and what it costs.

FAQs - CGI Windows & Doors in Miami
Do CGI impact windows in Miami really need the small Miami-Dade NOA sticker on the frame, or is that just for new construction?
The NOA sticker is required on every replacement or retrofitted impact opening in Miami-Dade County, not just new construction. If your CGI window or door lacks the Notice of Acceptance label that matches the product’s Miami-Dade approval, the installation wasn’t completed legally, and an inspector or insurance adjuster can flag it. We apply the correct sticker to every conversion we perform and won’t let a job leave our truck without it.
Why does my CGI Series 300 single-hung fog between the glass only on the lower half of the sash?
That’s a blown insulated glass unit. The desiccant inside the IGU has absorbed as much moisture as it can, and condensation starts in the lower corners where the two panes are closest. In Miami’s humidity cycles, that usually shows up within 10 to 15 years. The fix is a new IGU with a proper reseal, and if the frame is still square, the sash can often be rebuilt rather than replaced outright. Call (727) 620-6983 for a free assessment.
Can you convert my Hialeah jalousie windows to CGI impact windows without changing the wall opening?
In most CBS ranch homes built in the 1950s and 1960s, yes. We cut back the oversized aluminum buck, reframe the opening to the new impact window’s dimensions, set the CGI unit with Miami-Dade flanges, and flash and stucco the exterior to match. The jalousie itself is prohibited for replacement use in Miami-Dade County, so the conversion is a code requirement, not just a preference. We pull the permit, do the work, and apply the NOA sticker before the inspector arrives. Call (727) 620-6983 for a line-item estimate on your opening sizes.
The rollers on my CGI Classic-Pro slider in Brickell keep wearing out every few years. Is that normal?
For Brickell and Biscayne Boulevard, unfortunately, yes. The salt air off Biscayne Bay corrodes the roller assemblies far faster than inland Miami. If the rollers are wearing out repeatedly, the issue is often that the track has picked up corrosion pitting from salt, which then grinds down each new roller set. We’ll inspect the track and tell you honestly whether a track replacement is the real fix or whether it’s time for a full panel build. Call (727) 620-6983 and we’ll look at it.
Is a 1990s-era CGI window that passed Hurricane Andrew grandfathered under current Miami-Dade code?
A window that was legally installed and passed inspection under the code in effect at the time remains a compliant installation. But if the opening was later altered, converted from a jalousie, or the frame was damaged and repaired without a permit, the grandfathering may not hold. In Miami-Dade, the question isn’t whether the window passed Andrew; it’s whether the current installation matches the current NOA. We’ll check the paperwork and the frame condition before anyone starts cutting. Call (727) 620-6983 for a straight answer.
