AfterCGI Window Installation: The West Park Owner’s Guide
CGI window installation in West Park typically runs $340-$780 per opening for standard retrofit replacement, with most jobs completed in one day once materials arrive. We stock common CGI frame components and hardware for same-day repairs on the most frequently installed series, and we carry the full catalog for ordered replacement. Most West Park homeowners discover a CGI window problem when the sash won’t stay open, the lock won’t engage, or they feel air movement around a frame that used to seal tight against afternoon thunderstorms.
Which CGI Models This Applies To
CGI manufactures three primary residential lines you’ll find in West Park: the Sentinel impact-rated series, the Estate fixed and casement lines, and the Targa vinyl impact line. Each uses distinct frame extrusions, glazing stops, and hardware mounting patterns that do not cross over. The series name is stamped on the spacer bar visible when you open the sash, or on a label in the head jamb - check there before calling, because ordering the wrong glazing bead profile for a Sentinel versus an Estate wastes a week.
We stock OEM CGI parts where the manufacturer lead time is reasonable, and we source quality aftermarket equivalents for hardware and weatherstripping when the OEM option sits on backorder. The aftermarket truth for CGI: hinge and lock hardware from AmesburyTruth and Truth Hardware often exceeds original spec for corrosion resistance in salt-air environments, but glazing beads and frame splices should stay OEM to maintain the impact rating. We’ve measured enough retrofits in West Park to know that a 2-1/4 inch frame depth ordered for a 2 inch rough opening means either cutting stucco or ordering new - we check twice.
Signs Your CGI Window Installation Is Failing
- Sash drops or won’t stay open. The balance system - either a coil spring or block-and-tackle unit depending on CGI series - has lost tension. In West Park’s humidity, corrosion on the pivot bar or balance shoe accelerates this; we see it most on east-facing windows that catch morning condensation.
- Visible gap between sash and frame when closed. The weatherstripping has compressed past recovery or the frame has shifted in the opening. On homes near Sunview Park with original 1980s block construction, thermal movement in the wall can bow the jamb even when the window itself is sound.
- Lock tongue won’t extend or engage. The multipoint lock mechanism has seized, or the keeper has drifted out of alignment from repeated slamming. CGI’s multipoint systems are precise; a 1/16 inch keeper shift and the lock won’t throw.
- Condensation between glass panes. The insulating glass unit seal has failed. In South Florida, this typically shows at 8-12 years on standard IGUs, faster if the window faces direct afternoon sun and the edge seal sits in trapped heat.
- Frame corner separation or visible crack. The vinyl weld or aluminum mechanical joint has failed. Impact-rated frames take more stress from positive and negative pressure cycles; we’ve replaced corners on CGI Sentinel units after named storms where the glass held but the frame didn’t.

| Service | Price Range (West Park) |
|---|---|
| Standard CGI sash balance replacement | $180-$290 |
| Lock/keeper hardware set (single point) | $140-$220 |

What drives the range: frame material (aluminum versus vinyl), impact rating required, and whether the existing opening is plumb and square. Our quote includes the measured survey you keep, the written scope with line-item parts and labor, and the documented photo record on completion. The 365-Day Done Right Promise covers the installation; glass and hardware carry the manufacturer’s warranty. We pull permits where West Park requires them and pass inspection before final invoice.
DIY or Call Us?
What you can safely check: verify the series label, photograph the failed component, and confirm whether the issue is the hardware or the frame. What goes wrong fast: forcing a seized multipoint lock can snap the internal cam and convert a $200 repair into a full mechanism replacement. Removing an impact-rated sash without proper support risks glass breakage and personal injury - these units weigh significantly more than standard windows. And anything involving the insulating glass unit requires clean-room conditions; a speck of West Park construction dust between panes is permanent.
We carry common CGI balances, locks, and keepers on the truck. For full sash or frame replacement, we measure once, say what it costs, do the work. Call (786) 685-4706 to schedule your free estimate.
FAQs
Hardware typically lasts 10-15 years in South Florida’s salt-air environment; insulating glass units average 8-12 years before seal failure. East and south exposures, unshaded from afternoon sun, trend toward the shorter end. Call (786) 685-4706 for an exact quote on your specific series - estimates are free.
Sometimes. A balance can be re-tensioned if the spring isn’t corroded through; a lock keeper can be shimmed back into alignment if the frame hasn’t shifted. But glazing stops, IGUs, and cracked frame corners require replacement - no repair restores the original spec. We document what we find and show you before ordering.
Single-component repairs average 45-90 minutes on site. Full window replacement runs 2-4 hours per opening depending on stucco condition and whether the original frame was set with expansion foam or mechanical fasteners. We schedule arrival times, not four-hour windows.
We stock balances, single-point locks, keepers, and weatherstripping for the most common CGI series installed in West Park. Specialized hardware and complete sashes we order with confirmed lead times - typically 5-10 business days for standard colors, longer for custom finishes. We don’t start work until the part is in hand.
