Why Trust TruePane Windows & Doors for Your CGI Windows & Doors?

CGI builds a fine window. The aluminum is thick, the lamination is serious, and the hardware is heavy. But Cgi in Miami Beach and throughout the region is a hard place for any window, and CGI products have their own particular habits after ten or fifteen years of salt air, humidity, and August storms. Our technicians know those habits. We’ve rebuilt Sentinel casement operators down to the worm gear. We’ve re-tensioned Estate spiral balances on coastal homes where the original installer never adjusted the spring for laminated glass weight. We know that a Targa slider jumping its rail in July is usually a flattened set of rollers from 2011, not a framing problem. Dale Kessler, our owner, grew up in Kendall when it was still nurseries and canal roads, trained at Miami Dade College’s vocational program, and has been setting glass in South Florida for going on three decades. He still measures every job himself. That is not a marketing line. That is how we work.

As an independent CGI service provider, we answer to you, not to a factory rep’s sales quota. If a repair is the right call, we say so. If replacement is cheaper over a five-year horizon because the frame is racked or the glass is delaminating near the coast, we tell you that too, in plain language, with numbers on paper.

Common CGI Windows & Doors Problems We Fix in Miami

• Sentinel casement operators that crank but don’t move the sash. The Sentinel Series uses a worm-gear drive inside the operator. Over years of use, especially with heat and salt exposure, the splined crank shaft strips at the set screw and the worm gear develops dead spots. The crank turns, the arm barely moves. We stock replacement operators and gear assemblies, and we re-torque the arm to CGI’s 14 in-lb spec so the sash closes flush against the keepers.
• Estate double-hung sash drift and sudden drops. CGI’s Estate Collection spiral balances lose tension in coastal humidity, particularly when the sash carries laminated impact glass. The heavy lamination accelerates spring fatigue. When a sash starts drooping or slams shut on its own, it’s almost always the balance. We replace the spirals, re-tension for the actual sash weight, and adjust the tilt pins so the window operates smoothly again.
• Targa sliding door panels that jump the lower track. The Targa Series uses rollers that sit under significant weight, especially on 8-foot laminated panels. In Miami’s humidity and salt air, the roller bearings delaminate, flatten, and start grinding into the lower track. Eventually the panel hops the rail, usually on a summer afternoon when aluminum expands. We replace the rollers and dress the track if it hasn’t been chewed too badly. If the track is scored through the anodizing, we’ll tell you before we quote the roller job.
• Classic picture window weep-hole gaskets that trap water. On the Classic Series, the small rubber gaskets at the weep holes harden and shrink over time. Once they shrink, water that should drain outward sits in the sill dam and migrates into the frame. In a Miami rainy season, that means water stains, mildew, and eventually frame corrosion. It’s a cheap fix when caught early and an expensive one when ignored.
• Impact glass delamination near the coast. Laminated glass is two panes bonded around an interlayer. Salt air is relentless on the edges, and once air intrudes between the layers, the lamination starts to cloud from the edges inward. We see this most on homes within two or three miles of Biscayne Bay. Once delamination passes a few inches from the edge, the impact rating is compromised, and no repair restores it. Replacement is the honest recommendation.

CGI Parts & Our Repair-vs-Replace Approach

We stock OEM CGI parts. Rollers, balances, operator gears, stainless hinges, and weatherstripping. Those are the parts that affect impact ratings and wind-load performance, and we will not substitute aftermarket there. For cosmetic trim like interior stops, glazing beads, and sill dams, a quality aftermarket piece can save you real money without touching the window’s structural integrity. We will show you both prices and let you decide.

Our repair-vs-replace line is simple. If a Sentinel frame is still square and the lamination is intact, we rebuild the sash. If the frame is racked from storm stress, or the glass is delaminating near the coast, Cgi repair in Coral Gables or replacement is nearly always the less expensive long-term choice. A rebuilt window that lasts four years costs more by the decade than a proper replacement that lasts twenty. We would rather lose a small repair job than sell you a temporary patch. Call (754) 238-2201 and we’ll give you a straight answer.

Our CGI Service Process - Step by Step

1. 1
   Diagnosis. We measure the opening, check the frame for square, inspect the operator, balance, rollers, or gaskets, and identify exactly what failed. No guessing. We quote the repair or replacement on paper before any work begins.
2. 2
   Repair or install. For repairs, we use OEM or specified aftermarket parts as discussed. For replacement, we set the new unit level and true, shimmed correctly for the rough opening, and anchored to Miami-Dade HVHZ standards. That includes proper flange taping and sealant continuity at the sill.
3. 3
   Test. We operate the window or door through its full range, check the seal with a water test where appropriate, and confirm the locking hardware seats properly. On impact products, we verify the lamination is clean and the frame is square.
4. 4
   Warranty registration. Before the truck leaves your driveway, we register both manufacturer warranty layers in writing, with durations stated. That is The Keystone Standard. You get a copy. There’s no arguing later about who said what.

CGI Products We Service & Install in Miami

We service and install every major CGI product family sold in the South Florida market: the Sentinel Series casements and awnings, the Estate Collection double-hungs and sliders, the Targa Series sliding doors and multi-slide panels, and the Classic Series picture windows and single-hungs. We keep the most common Miami failure parts on our shelving: Sentinel operator gears, Estate spiral balances, Targa rollers, Classic weep gaskets, and the stainless steel hinges shared across multiple CGI lines. If you have a CGI product and you’re not sure which series it is, describe the hardware or send a photo, and we’ll identify it on the phone.

Our CGI work covers three sub-services that matter most in Miami-Dade and Cgi repair in Key Biscayne. Hurricane impact windows, where the frame, the lamination, and the anchoring system all have to work together to pass code. Impact sliding glass doors, where a properly tuned roller and track are the difference between a door that opens in November and one that doesn’t. And wind mitigation and code compliance, where the paperwork and the installation both have to be right for your insurance discount to hold.

We Also Service These Brands

CGI is a big part of our work, but we are not tied to one manufacturer. TruePane is an authorized installer for more than a dozen lines, and we service, and PGT just as deeply. If you have a mixed home, an original Andersen in the front and a CGI slider out back, we can handle both. That matters in Miami, where remodels rarely happen all at once.
