CGI Window Replacement: The Lauderdale Lakes Owner’s Guide

CGI window replacement in Lauderdale Lakes typically runs $340-$780 per opening installed, depending on whether you’re swapping a standard fixed pane or a full impact-rated operating unit. We stock CGI-compatible sash assemblies, balance systems, and glazing bead profiles for same-day replacement on most series, and we carry the measured survey to your door before any work is scheduled. Most Lauderdale Lakes owners discover the problem when a window that once sealed quietly during afternoon thunderstorms starts rattling, weeping condensation between panes, or refusing to lock flush against the frame.

Which CGI Models This Applies To

CGI’s product line breaks into distinct series, and the replacement part you need depends on which generation is installed in your wall. The Estate Series, Sentinel by CGI, and Targa by CGI each use different frame depths, glazing pocket dimensions, and hardware mounting patterns. We see the most replacement volume in Lauderdale Lakes on Estate Series single-hung and horizontal roller units installed between 2012 and 2019, particularly in the Oriole Gardens and Westwood Park areas where original aluminum-frame new construction windows have reached their service limit.

To identify your series, check the etched mark in the glass corner or the label on the frame jamb. The model number format matters: EST- followed by dimensional codes indicates Estate Series, while TGA- or SEN- prefixes point to Targa or Sentinel lines. Hardware from one series rarely transfers to another. The balance shoes in a Targa single-hung, for instance, mount on a 5/8-inch channel width that won’t seat in an Estate frame designed for 3/4-inch.

We source OEM CGI parts where the series is still in production and match spec-grade aftermarket components for discontinued lines. The aftermarket decision isn’t about cutting cost; it’s about whether CGI still stamps that extrusion. When they don’t, we machine-compatible replacement profiles from commercial-grade 6063-T6 aluminum and pair them with glazing that meets the original design pressure rating. If the measurement isn’t written down, it doesn’t exist.

Signs Your CGI Window Replacement Is Failing

• Visible moisture or fog between glass panes. The insulated glass unit (IGU) seal has breached, allowing South Florida’s humid air to enter the airspace. Once desiccant saturation occurs, the thermal performance drops and the Low-E coating begins degrading from edge exposure.
• Window refuses to stay open or slams shut unexpectedly. The balance system, whether coil spring or block-and-tackle, has lost tension or the pivot bar has worn. In CGI single-hung units, this often traces to corrosion at the balance shoe from years of condensation weeping down the jamb.
• Locking mechanism engages but the sash still shifts. The keep (strike plate) has wallowed out or the multipoint locking rod has bent from repeated over-torquing. This is a security gap, not merely a convenience issue, and it shows up first on windows facing prevailing easterlies that take the full force of Lauderdale Lakes’ storm-season pressure cycles.
• Glazing bead pulling away from the frame or cracking. PVC beads degrade faster than aluminum in UV exposure, and CGI’s earlier PVC formulations were particularly susceptible to embrittlement after eight to ten years of direct sun. Once the bead loses flexibility, the glass edge is no longer cushioned and impact resistance drops measurably.
• Frame corners weeping water during hard rain, even when closed. The sill pan or end dam sealant has failed, or the weep holes are blocked with debris. In retrofit installations where the original rough opening wasn’t properly flashed, this can also indicate water intrusion behind the fin that demands more than part-level repair.

Replacement Cost & What’s Included

What drives the range: frame condition, whether the opening requires new flashing, and whether we’re matching a single unit or multiple units in the same wall plane. Every quote we write in Lauderdale Lakes includes the measured survey you keep, the written scope of work, parts and labor as separate line items, permit handling if required, and the documented photo record delivered after completion. The 365-Day Done Right Promise applies to every replacement; if the sash doesn’t seat, seal, and operate as specified, we return and correct it under Haven Clause 5 (No Surprises).

DIY or Call Us?

There is one check any owner can safely perform: open the sash fully, examine the interior frame label, and photograph any etched glass markings. That documentation is what we need to spec the correct replacement before we arrive.

What goes wrong with DIY on CGI windows: the balance systems are under spring tension that can release unpredictably when the sash is removed without proper support. The glazing beads snap if pried with metal tools rather than polymer shims. And impact-rated glass units weigh substantially more than standard annealed; a dropped IGU is a complete loss, and the sharp edge hazard is real. We do not recommend homeowners remove operating sashes or attempt IGU swaps.
