AfterCGI Windows & Doors in Miami, CA | Sightline Windows & Doors
We provide independent CGI window and door service across Miami, and the thing that separates our work here from anywhere else is the HVHZ paperwork. Every CGI unit we touch in Miami-Dade County has to clear the Notice of Acceptance standard, which is stricter than anything else in the country. We’re not manufacturer-affiliated, so our loyalty is to the building and the inspection, not a brand rep. Call (509) 265-6387 for a written price before any work starts.
Why Miami Residents Choose Us for CGI Service
Sonia Raman, our owner, has spent over a decade diagnosing and replacing CGI windows and doors in Miami-Dade’s HVHZ market. She knows how their impact-rated product lines hold up to salt air, humidity, and hurricane cycles because she’s measured the failures herself, not read about them in a spec sheet. Our team works from the same discipline: measure once, write it down, then measure again.
We’re an independent CGI service provider, not manufacturer-affiliated or authorized. That means when we recommend a repair versus a replacement, the recommendation is based on what the frame and glass actually need, not what a factory program pays us to push. For Miami homeowners facing recertification deadlines, that distinction matters. We use authentic CGI replacement glass, sashes, and hardware whenever it’s available, and when it’s not, we source certified impact-rated aftermarket parts that match Miami-Dade NOA specs. Every job leaves with a documented photo record, and every quote is written before a tool is lifted.
Common CGI Windows & Doors Problems We Solve in Miami
- Fogging and seal failure in CGI insulated glass units. Miami’s humidity sits above 75% most of the year, and the salt-laden air near the coast accelerates IGU seal degradation. We see this constantly in beachfront high-rises where CGI units from the early 2000s have lost their argon fill and started condensing between the panes. Once the seal fails, the impact rating is compromised. That’s a recertification problem waiting to happen.
- Aluminum frame corrosion and pitting on CGI frames. Install a standard CGI frame without marine-grade Kynar coating within a mile of Biscayne Bay, and you’ll see oxidation within 8 to 10 years. Coconut Grove and Surfside are the worst zones. The pitting isn’t cosmetic; it eats into the structural channel where the glazing bead sits, and eventually the window can’t hold a proper seal against wind-driven rain.
- Roller and track binding in CGI horizontal rollers and 3-lite sliders. Salt and sand work their way into the tracks, especially in ground-level units and homes near the water. The rollers grind, the track gets scored, and the panel starts to bind. Left alone, the operator gets forced and the hardware strips. We clean, replace rollers, and re-align tracks before the frame takes damage.
- Weep hole clogging in CGI frames causing water intrusion. Miami’s summer rain comes in sheets. When weep holes clog with salt crust and debris, water backs up inside the frame and finds the drywall. We’ve opened walls in Little Havana where the leak was traced to a CGI frame whose weep system hadn’t been cleared since installation. The fix is simple; the drywall repair isn’t.
- Failed or frozen CGI balance systems in single and double hung windows. Constant humidity plus salt exposure corrodes the balance springs and tubes inside the frame. The sash gets heavy, drops suddenly, or won’t stay up. On a second-story window that’s a safety issue. We replace balances with corrosion-resistant hardware and re-tension the sash to spec.
BeforeAfterCGI Service in Miami: What Local Conditions Mean for Your Equipment
Here’s the fact that changes everything about owning CGI windows in Miami: Miami-Dade’s mandatory 40-year building recertification law means aging CGI windows installed in 1980s Brickell and Edgewater condo towers are now being flagged as non-compliant because their impact ratings predate current HVHZ NOA standards. A window that was code-compliant in 1987 is not code-compliant for recertification in 2027. The inspector doesn’t care that it’s still holding glass; they care whether the unit carries a current Miami-Dade Notice of Acceptance. That single regulation creates building-wide replacement contracts along Brickell and Collins Avenue at a frequency you simply don’t see in Tampa, Orlando, or anywhere else in Florida. For a condo association, this isn’t a maintenance line item. It’s a structural deficiency finding, which means the replacement has to be specified, permitted, and documented under HVHZ rules or the building can’t pass. When we survey these towers, we’re not just counting windows. We’re reading NOA numbers, checking impact-rating labels, and building a replacement schedule that lines up with the recertification deadline.
CGI Models & Products We Service in Miami
We service the full CGI residential and commercial range: Sentinel Series impact windows are the most common line we see in Miami, particularly in CBS homes built after Hurricane Andrew. The Estate Collection and Classic Series show up in a lot of 1990s and early 2000s tract construction across west Miami-Dade, and the Hialeah line is heavy in the city of Hialeah itself, where the original jalousie windows finally gave way to impact-rated replacements. We stock common CGI glass packs, rollers, balances, and hardware locally so turnaround stays short for the lines Miami homes actually have. When a frame is too far gone, we recommend full-frame replacement over repeated insert repairs, and we specify the replacement based on performance tier and HVHZ compliance, not what’s sitting in a warehouse.
CGI Service Pricing in Miami
CGI service in Miami typically runs between $175 and $850 for most hardware and seal repairs, and $900 to $2,800 per opening for full-frame Sentinel Series impact window replacement, depending on size, access, and how much the existing frame has degraded. What drives the cost: whether the unit needs a glass pack replacement or a full tear-out, whether the building requires boom lift access, and whether the property sits in a coastal zone requiring higher design pressures. Your written estimate includes parts, labor, permit documentation, and the measured survey you keep. We don’t start work until you’ve seen the number on paper. Call (509) 265-6387 for an exact quote.

FAQs - CGI Windows & Doors in Miami
No, not automatically. Only specific CGI lines carry current Miami-Dade NOA approval for HVHZ use. The Sentinel Series is the most commonly NOA-listed CGI line in Miami right now, but older Estate Collection and Classic Series units from the 1990s may not carry current approvals, even if they were legal when installed. We verify the NOA number on the unit itself before recommending repair or replacement. Call (509) 265-6387 and we’ll check your window labels during the estimate.
Impact rating and seal integrity are two separate things. The impact rating comes from the laminated glass and frame anchoring; the fogging comes from a failed insulated glass unit seal. Miami’s humidity and salt air push moisture into the space between the panes once the seal degrades, and that moisture shows up as fog. On waterfront properties, we see this happen in under a decade. Fogged CGI glass needs a glass pack replacement, which we handle under NOA-compliant specs. Call (509) 265-6387 for a written price.
Sometimes. If the CGI frame is structurally sound and carries a current NOA listing, we can replace the insulated glass unit and re-glaze it in place. But if the frame shows aluminum pitting, corrosion at the seams, or repeated seal failures, re-glazing is a short-term patch on a frame that won’t hold a proper seal. In those cases we recommend full-frame replacement. We’ll show you the frame readings during the survey so you can see what we’re seeing. Estimates are free at (509) 265-6387.
Yes, in many cases, but the unit has to pass the Miami Beach historic preservation board’s design review. The board restricts aluminum color, profile depth, and muntin patterns, which means a standard white Sentinel Series won’t always clear the review for an Art Deco building. We’ve worked with CGI’s custom finishes and narrower profile options to meet board requirements, and we’ve also watched boards reject units outright for the wrong sightline. The NOA compliance is the easy part; the design review is the variable. Call (509) 265-6387 and we’ll tell you what’s likely to pass before you spend a dollar on glass.
In a direct-waterfront Coconut Grove building, plan on 20 to 25 years for a properly maintained CGI frame, and 8 to 10 years for the first seal failure if the frame lacks marine-grade Kynar coating. Units with Kynar coating and stainless hardware can stretch the frame life to 30 years or more, but the glazing seals don’t care about the coating. They degrade from humidity and salt regardless. When we survey a condo unit, we check both the frame condition and the glass pack seals, because one can outlive the other by a decade. Call (509) 265-6387 for a measured survey on your unit.
