AfterCGI Windows & Doors in Miami Beach, FL | Winslow Windows & Doors
We provide independent CGI window and door service throughout Miami Beach, from South Beach Art Deco buildings to Collins Avenue high-rises. Our quick answer: if your CGI units are binding, corroding, or leaking air on this barrier island, the culprit is almost always salt-air damage to hardware or gaskets, and we fix it with marine-grade parts that outlast the originals. Call (727) 860-0593 for a free estimate.
Winslow Windows & Doors has worked on more CGI products in HVHZ salt-air conditions than any mainland installer we’ve ever traded notes with. We know exactly how the 9500 Series behaves three years into oceanfront exposure, what the Estate Collection does on a south-facing South Beach wall in August, and why the Targa’s standard rollers seize up faster than the warranty suggests. We’re independent, so we’re honest about what needs OEM parts and what needs an upgrade.
This page is for Miami Beach homeowners who own CGI windows or doors and want straight answers: what breaks, what it costs, and who can actually fix it without making the problem worse. That’s us.
Why Miami Beach Residents Choose Us for CGI Service
We’ve been at this since 2011, and Ed Winslow’s name is on every truck, every invoice, and every job we finish. Ed grew up in Brownsville and trained in building construction technology at Miami Dade College before spending years in the field learning windows from the frame out. When a CGI unit fails on this island, it fails differently than it does in Hialeah or Kendall, and that’s the knowledge you’re paying for.
We keep OEM-compatible parts and marine-grade stainless steel hardware on hand for the CGI models most common in Miami Beach: the 9500 Series, Estate Collection, Targa Series, and Classic Series. A live person answers our phone 24 hours a day. No voicemail loops, no call centers. When you call about a CGI window that won’t close on a Sunday evening with a storm rolling in off the Atlantic, you get a person who knows what you’re describing.
Every technician who shows up at your door is background-checked and in uniform. You’ll know exactly who you let in before the truck pulls away from the curb. And our CGI sales & service work carries the Done Right Promise: if it’s not done right, we make it right. That’s not a warranty card in a drawer. That’s Ed’s word.
Common CGI Windows & Doors Problems We Solve in Miami Beach
- Salt-air pitting and seizure of horizontal slider rollers. CGI’s standard stainless steel rollers on horizontal sliders start pitting within three to five years of oceanfront exposure on this island. The rollers grind, then bind, then the door won’t move at all. We replace them with marine-grade rollers built for continuous salt spray, not just splash exposure.
- Loss of air-seal integrity on 9500 Series casement windows. The gaskets on CGI 9500 casements compress over time under constant UV and salt. Wind-driven rain starts finding its way past the seal, especially on east-facing units above Collins Avenue or Ocean Drive. We replace the gasket sets and re-test the seal, often same-day during the dry season.
- Thermal bowing of dark-framed Estate Collection windows. South-facing elevations in South Beach bake in the summer sun. Dark bronze and black CGI Estate frames absorb that heat and bow slightly, which pulls the latch out of alignment. You’ll feel the sash resist, then pop when you finally force it. We realign the latches and, where needed, reinforce the frame to prevent recurrence.
- Corrosion-induced failure of balance springs in single-hung windows. Oceanfront condos with CGI single-hungs see their balance springs corrode from constant salt mist. The sash drops when you raise it, or won’t stay up at all. We replace the balances with marine-grade stainless steel and re-hang the sash so it operates like the day it was installed.
- Frame pitting and seal failure on older CGI units. If the frame itself is pitted and the seals are gone in multiple places, patching becomes a losing game. We’ll tell you honestly when repair makes sense and when full replacement is the only way to keep your HVHZ compliance intact.
CGI Service in Miami Beach: What Local Conditions Mean for Your Equipment
Miami Beach sits entirely inside Florida’s High Velocity Hurricane Zone (HVHZ) on a narrow barrier island with the Atlantic on one side and Biscayne Bay on the other. Every Miami Beach Window Installation must carry a Miami-Dade Notice of Acceptance (NOA), the strictest product certification in the country. But the NOA doesn’t tell you what the salt spray will do to your hardware after three years. We’ve replaced rollers on Collins Avenue buildings that looked like they’d been sandblasted. Standard stainless steel doesn’t survive this environment. Marine-grade 316 stainless does, and that’s what we install.
On top of that, properties in the South Beach Art Deco Historic District answer to the Miami Beach Historic Preservation Board. Impact Windows in Miami Beach replacements for those 1920s and 1930s buildings must match the original steel casement sightlines. That means slim stiles, historically appropriate muntin grids, and often custom mulling. A Miami mainland installer showing up to a Euclid Avenue job with off-the-shelf impact windows will get sent back across the causeway. We’ve been through this review process enough times to know what gets approved and what gets rejected before a permit is even pulled.
The practical result: a CGI window in Miami Beach doesn’t just need to stop wind and water. It needs to survive a salt environment that eats hardware for breakfast, and in the historic district, it needs to look like it belonged there in 1935. That’s the work we do.
CGI Models & Products We Service in Miami Beach
We service the full CGI residential lineup you’re likely to find in Miami Beach: the Estate Collection (their premium aluminum impact line, common in mid-rise and luxury condos), the 9500 Series (their workhorse casement and single-hung line, found all over South Beach), the Targa Series (horizontal sliders and stacking doors, popular in condo conversions), and the Classic Series (where it’s still in service in older buildings).
Our parts policy is simple. Where safety or NOA recertification is at stake, we use genuine CGI OEM parts. Where durability is the bigger concern, we upgrade to marine-grade stainless steel hardware aftermarket components that hold up better in oceanfront air. We stock the common parts locally for faster turnaround on Miami Beach jobs. If we have to order something from the manufacturer, we’ll tell you exactly how long it takes before you agree to anything.

FAQs - CGI Windows & Doors in Miami Beach
Yes. We’ve completed multiple Historic Preservation Board-approved CGI replacements in the South Beach district, including on Euclid Avenue. The key is matching the original sightlines and muntin patterns, which often means custom-mulling CGI Estate Collection units with slim stiles. We handle the board review paperwork as part of the job. Call (727) 860-0593 to have us look at your building.
We replace the standard CGI stainless steel rollers with marine-grade 316 stainless rollers designed for continuous salt spray. On Collins Avenue buildings, this upgrade typically doubles or triples the life of the roller assembly. We also clean and lubricate the track, and we’ll tell you if the track itself is too pitted to save. Call (727) 860-0593 for an assessment.
The gasket has likely compression-set from UV and salt exposure. The fix is a full gasket replacement and seal test, which we can usually do in one visit. Don’t wait. Wind-driven rain leaking past the seal is how you get water damage behind the wall. Call (727) 860-0593 and we’ll get it sealed before the next storm.
Yes, if the frame is structurally sound. We can replace the cracked lite with matching impact-rated glazing and retain the unit’s NOA compliance. If the crack has compromised the laminated interlayer or the frame shows corrosion at the glazing channel, full replacement is the safer call. We’ll show you exactly what we see before we recommend anything.
It depends on how deep the pitting goes. Surface pitting on hardware is repairable. Pitting that has eaten into the frame extrusion itself, especially at the corners or glazing channel, compromises the structural integrity of the impact rating. When the frame is compromised, replacement is the only way to maintain HVHZ compliance. We’ll never sell you a replacement when a repair does the job. Call (727) 860-0593 for an honest assessment.
