CGI Windows & Doors in Miami, CA | Lightwell Windows & Doors
We’re an independent CGI service team based right here in Miami, and the short answer is this: we repair and replace CGI impact windows and doors across Miami-Dade County, and the thing that sets our Miami Window Replacement work apart locally is that we check the Miami-Dade Notice of Acceptance (NOA) on every unit before we touch it. That paperwork question determines whether a repair is even legal here. If you need straight answers on your CGI windows, call (562) 478-8017 and we’ll walk you through what you’re actually dealing with.
Why Miami Residents Choose Us for CGI Service
We’ve spent years documenting CGI product lines against Miami-Dade’s High Velocity Hurricane Zone requirements, and that changes how we approach every job. A CGI window that’s fine in Tampa might not be legal in Miami, and we check that before quoting anything. Keith Yamada, our owner, grew up in Gardena and trained at Los Angeles Trade-Technical College, where he learned to read rough openings and load paths by hand before he ever sold a window. He brought that same care to CGI service here, and it shows in how we handle each job, from the first measurement to the final clean-up. We’re not affiliated with CGI, and that’s the point. Our loyalty is to the homeowner, not a manufacturer’s sales target, so our repair-versus-replace advice is based on what will actually pass inspection and survive Biscayne Bay salt air. We also carry OEM and OEM-spec aftermarket CGI parts for faster turnaround, because waiting three weeks for a roller assembly when your sliding door won’t lock is not something a Miami family should have to do.
Common CGI Windows & Doors Problems We Solve in Miami
- Aluminum frame corrosion and pitting on ocean-facing elevations. We see this constantly in Miami Beach and Sunny Isles, where salt-laden air from the Atlantic eats into CGI impact frames within a few years. The corners go first, then the weep holes clog, and water starts finding its way inside the track.
- Weatherstripping and gasket breakdown from humidity above 70% year-round. Miami’s unrelenting moisture degrades the seals on CGI sliding and hung units faster than in inland Florida. Once those gaskets go, wind-driven rain leaks follow, and the impact seal that your NOA rating depends on stops doing its job.
- Roller and track degradation in CGI impact sliding doors. Salt air and grit get into the track, the rollers grind down, and the panel starts binding. Eventually the lock won’t engage at all, which is a serious problem when a storm is coming and your door won’t secure.
- Frozen hardware on CGI casement and awning frames. Coastal corrosion seizes the cranks and hinges, and the window becomes inoperable long before the glass itself fails. This is especially common in older CBS homes where the original hardware was never upgraded for a corrosive environment zone.
- Non-compliant jalousie windows in mid-century homes. This is the bread-and-butter replacement job across Hialeah, Little Havana, Kendall, and West Miami. Those original louvered windows were built for pre-AC cross-ventilation, and they provide almost no hurricane resistance. Many insurance carriers now flag or non-renew policies on homes that still have them.
CGI Service in Miami: What Local Conditions Mean for Your Equipment
Here’s the thing most homeowners don’t learn until a contractor tells them: Miami-Dade County sits within Florida’s High Velocity Hurricane Zone, which means every window and door installed here must carry a Miami-Dade Notice of Acceptance, not just the statewide Florida Product Approval used in Orlando or Tampa. That single paperwork standard determines whether your existing CGI unit can be repaired in place or has to be replaced, because a unit that lost its NOA compliance, or never had it, cannot legally stay in your wall if you’re doing permitted work. We check the NOA status on every CGI unit before quoting a job, because it’s the fastest way to know if you’re looking at a roller replacement or a full frame replacement. The salt air and humidity just accelerate the timeline. In neighborhoods like West Miami and Little Havana, where mid-century CBS homes still have original openings, matching a NOA-compliant CGI assembly to an existing rough opening is the difference between a one-day job and a two-week project. That’s why we measure first and talk options second.
CGI Models & Products We Service in Miami
We service the full CGI impact lineup, including the Sentinel Impact Series for aluminum impact windows and doors, Commercial Impact Storefront & Entrance Systems for ground-floor retail and condo entries, the Vinyl Impact Series covering single hung, double hung, and horizontal rollers, and Hurricane-Rated Sliding Glass Door Systems. Our approach to parts is simple: where the assembly is serviceable, we source OEM or OEM-spec aftermarket CGI rollers, weatherstripping, gaskets, locks, and operators. The impact rating lives in the frame-and-glass system as a whole, so the parts have to match. We stock common CGI roller assemblies and gasket profiles locally for faster Miami turnaround, and for less common hardware we can typically have it in hand within a week. When a CGI unit has lost its NOA compliance, has corroded structural corners, or has failed impact glass, we recommend full replacement over chasing parts, especially when an insurance policy renewal is hanging on it.
CGI Service Pricing in Miami
Most CGI window and door service in Miami falls into a few clear buckets. A roller and track rebuild on a sliding door typically runs $220 to $480, while weatherstripping and gasket replacement on a hung or rolling unit usually lands between $180 and $360 per opening. Hardware repair like a seized casement crank or a failed lock runs $95 to $240. Full CGI impact window replacement in a standard CBS opening runs $1,400 to $2,900 per opening installed, and full frame replacement on older Miami homes, where the original rough opening needs reframing, can push toward $4,000 or more per opening. Several things drive the cost: whether the unit still carries a valid NOA, where the home sits relative to the corrosive environment zone, and whether we’re matching an existing rough opening or reframing. A free estimate covers all of it, and the written price you get is the price you pay. Call (562) 478-8017 and we’ll give you exact numbers for your home.

FAQs – CGI Windows & Doors in Miami
Yes. Miami-Dade County requires a Notice of Acceptance (NOA) on every window and door installed here, which is a stricter product approval standard than the statewide Florida Product Approval used elsewhere. We check the NOA status on every CGI unit before quoting any repair or replacement, because a unit without a valid NOA cannot stay in the wall if permitted work is being done. If you’re not sure what your windows carry, call (562) 478-8017 and we’ll help you figure it out.
Most of the time, yes. Rollers, weatherstripping, gaskets, locks, and operators can usually be replaced with OEM or OEM-spec aftermarket parts without touching the impact glass or frame. But if the unit has lost its NOA compliance, the frame corners are structurally corroded, or the impact glass itself has failed, replacement is the honest recommendation. We’ll tell you which path makes sense for your specific unit before any work begins.
Miami’s combination of Atlantic and Biscayne Bay salt air, humidity that stays above 70% all year, and direct exposure to major hurricane tracks creates what Miami-Dade code calls a corrosive environment zone. Frames in these zones need enhanced corrosion resistance, and CGI frames that were not specified for coastal exposure will pit and corrode on the ocean-facing elevations within a few years. This is not a manufacturer defect; it’s what salt air does to aluminum, and it’s why we inspect the corners and weep holes closely on every coastal job.
In most cases, yes. Many insurance carriers in the current Florida market specifically flag or non-renew policies on homes that still have original jalousie windows, because those louvered units provide almost no hurricane resistance. Replacing them with NOA-compliant CGI impact windows removes the flag and often unlocks wind mitigation credits. The insurance savings alone sometimes offsets a meaningful chunk of the replacement cost. Call (562) 478-8017 for a free estimate, and we’ll specify the exact CGI assemblies your home needs.
We do, and we know what those jobs involve. High-rise condo replacements in Miami’s corridor from Brickell to Sunny Isles require condo association approval, structural engineer sign-off, and coordination with building management, often with strict working hours and staging rules. We handle that paperwork and coordination on your behalf, and we’ll keep the association in the loop so the job doesn’t stall mid-permit. We also offer Cgi in Pembroke Pines for homeowners in that area. Call (562) 478-8017 to start the conversation.
