CGI (Custom Glass Industries) impact windows and doors are everywhere in Florida City for good reason. The city’s position as the last incorporated mainland city before the Keys means every exterior opening must meet Miami-Dade’s Notice of Acceptance standards, and CGI built a reputation for aluminum impact frames that satisfied those requirements at a competitive price point through the 1990s and 2000s. The bulk of Florida City’s housing stock was rebuilt after Hurricane Andrew under those strengthened codes, and many of those original CGI units are now thirty years old, entering a simultaneous wave of seal degradation, hardware corrosion, and operational failure.

We are not affiliated with or authorized by CGI. We are an independent service provider that specializes in their products because we know their profiles, their hardware schedules, and the specific ways they fail in this environment. That independence means we can source across OEM, aftermarket, and compatible lines to find the right part for your specific unit, not just the part in a single manufacturer’s catalog.

Why Trust Sightline Windows & Doors Florida City for Your CGI Windows & Doors?

Sonia Raman leads our Florida City operation, and she has spent well over a decade doing windows and doors work across South Florida. She grew up in Miami and picked up her first glazing tools at Miami Lakes Educational Center, where the instructors were less interested in theory than in whether your cuts were square and your measurements repeatable. Her crew has logged steady hours serving Florida City properties, including jobs near Homestead Bayfront Park, where Cgi repair in Homestead addresses salt air from two directions that corrodes aluminum frames measurably faster than locations even 20 miles inland. She is known specifically for impact-rated window specifications: matching frame depth, glass thickness, and DP rating to what the structure and the Florida Building Code actually require, not to what fits a price sheet.

Our technicians carry license numbers on their uniforms, verified under Haven Clause 3 before they arrive at your door. Every CGI service call begins with a measured survey you keep, and the written quote cannot differ from that document. We document every visit with a photo record, standard under the Haven Standard, not an upsell. Our 365-Day Done Right Promise is stamped on every job, not offered as a courtesy.

On slow Fridays, Sonia still pulls up the AAMA performance standard documents and reads them the way some people read the news. That habit shows in our work. We have seen CGI units that were “properly” installed by others with anchor spacing that violated the NOA submittal, and we say so plainly before you sign anything. A window rated for 140 mph wind is not a selling point if it was installed with the wrong anchor spacing.

Common CGI Windows & Doors Problems We Fix in Florida City

• Roller assembly failure on CGI Series 7000 Horizontal Rollers and Series 8000 Sliding Glass Doors. The stainless steel rollers in these units corrode in Florida City’s bidirectional salt air, causing the sash to drag and the track to rack. Once the track deforms, the impact seal compresses unevenly and wind-driven rain finds its way in. We see this pattern constantly in post-Andrew rebuilds near the bay, where ground-level salt-humid air wicks under the sill track and accelerates corrosion beyond what the manufacturer anticipated.
• Seal and gasket degradation leading to fogged glass and water infiltration. CGI’s insulated glass units rely on a dual-seal system: a polyisobutylene primary seal and a silicone secondary seal. After 25-30 years of thermal cycling in South Florida, both seals harden and lose adhesion. The result is argon loss, condensation between panes, and eventually water intrusion during storm events. We replace the entire IGU, not just the visible gasket, because the failure is always deeper than it appears.
• Corrosion of stainless steel hardware and fasteners. “Stainless” does not mean “immune” in this environment. Florida City’s salt-laden air attacks 300-series stainless at the grain boundaries, particularly where fasteners were over-torqued during original installation, creating stress-corrosion cracking sites. We replace with higher-grade hardware or specify coated alternatives when the original part is no longer available.
• Hinge and lock misalignment on CGI entry doors and French doors. Thermal expansion of aluminum frames, combined with settling of post-Andrew slab foundations, throws door geometry out of square. The multipoint locking systems then fail to engage fully, creating air infiltration, water leaks, and a security gap. We diagnose with a sightline measurement, then shim or rehang to restore proper engagement.
• Frame corrosion at weep holes and sill junctions. CGI’s aluminum frames depend on clear weep pathways to drain condensed moisture. When salt buildup clogs these passages, water pools at the sill-frame junction and initiates pitting corrosion. We clean, re-establish drainage, and apply compatible sealants where the original has degraded.

CGI Parts & Our Repair-vs-Replace Approach

We source OEM CGI parts when available and use high-quality aftermarket equivalents that meet or exceed Florida impact and structural requirements for out-of-production components. Several CGI Series 5000 and 7000 configurations were discontinued in the mid-2010s, and the lead time on remaining OEM inventory can stretch to eight weeks. We maintain local stock of compatible roller assemblies, weatherstrip profiles, and IGU spacer systems that match the original thermal and structural performance.

Our Window Installation services repair-vs-replace assessment is straightforward. If the frame is square, the glass is intact, and the failure is isolated to hardware or seals, we recommend refurbishment. A typical CGI Series 7000 roller and seal refresh runs $280-$420 per opening, including the IGU if fogged. If multiple seals have failed, the frame shows corrosion pitting deeper than 1/16 inch, or the unit was installed without proper anchorage to begin with, full replacement is more cost-effective. We will show you the frame reading and explain which side of that line your unit falls on. Call (786) 418-6182 for a written quote.

Our CGI Service Process - Step by Step

1. 1
   Diagnosis with measured survey. We arrive with the specific CGI hardware schedules for your series and year. We measure frame squareness, check anchor spacing against the NOA submittal, test roller drag with a spring gauge, and photograph every condition. You keep the measured survey.
2. 2
   Written scope and price. Haven Clause 1: the quote is the same document as the survey. We specify every part by source (OEM CGI, aftermarket compatible, or cross-referenced equivalent) and note any code-required upgrades.
3. 3
   Repair or install with verified crew. Our technicians are background-checked, uniformed, and identified by license number. For CGI impact units, we verify the replacement glass carries the correct Miami-Dade NOA number and the frame label matches the approved product description.
4. 4
   Operational test and seal verification. We cycle every moving component 20 times, check multipoint lock engagement with feeler gauges, and perform a water spray test on repaired seals. The photo record documents each stage.
5. 5
   Warranty documentation. The 365-Day Done Right Promise is written on the final invoice, along with the photo record access. If it’s not done right, we make it right.

We stock locally: OEM-spec roller assemblies for Series 7000 and 8000, compatible weatherstrip for all four series, and IGU spacer systems rated for Miami-Dade’s large-missile impact requirements. For discontinued frame colors, we source powder-coated matches or recommend compatible alternatives from our other manufacturer lines.

Our eight verified manufacturer lines give us cross-reference capability that single-brand shops cannot match. We regularly service and install PGT, CWS, ES Windows, and ECO Window Systems impact products in Florida City, and we can specify alternatives when a CGI Windows & Doors in Leisure City, FL unit is beyond repair or when a customer wants to compare performance tiers. That breadth means we recommend by what the opening requires, not by what is in stock.

How long does CGI service take?

Most CGI hardware and seal repairs in Florida City are completed in one visit, typically 2-4 hours per opening.

Will service void my CGI warranty?

CGI’s original product warranties were typically 10-20 years and have largely expired on the units installed in Florida City’s post-Andrew rebuild wave.
