CGI Window Replacement: The Belle Glade Owner’s Guide

CGI window replacement in Belle Glade typically runs $340-$780 per opening for installed sash, frame, or hardware replacement depending on the series and whether the unit is impact-rated. We stock common CGI parts on our trucks and can usually source same-day what we don’t carry. Most Belle Glade owners discover the problem when a window that used to glide starts catching, or when they notice daylight between the sash and frame after a storm season.

Which CGI Models This Applies To

CGI’s product line breaks into three main series that you’ll find across Belle Glade homes built from the late nineties forward. The Estate Series uses heavier aluminum extrusions with a 3-inch frame depth, common in pre-2010 construction near the cane fields. The Sentinel Series, their impact-rated line, carries a thicker interlayer and different glazing bead profile that is not interchangeable with standard Estate hardware. The Targa Series sits between them on price and frame wall thickness.

To identify your series, check the etched mark in the glass corner or the sticker on the frame jamb. The part number format matters: Estate hardware uses a four-digit prefix, Sentinel impact units add an “S” designation that changes the roller and lock geometry. We see this trip up owners who order Estate rollers for a Sentinel window and find the axle spacing is off by 3/16 inch. That is enough to bind the sash.

We carry OEM CGI parts and select aftermarket equivalents where the spec matches. For Sentinel impact latches, we use OEM only; the interlock tolerances are too tight for generic hardware. For Estate rollers and balances, we stock a Florida-made equivalent that meets the same 100-pound sash weight rating at roughly 60 percent of the CGI part price. We will show you both options on the written quote and mark which is which.

Signs Your CGI Window Replacement Is Failing

• The sash drops or won’t stay open. This usually means the balance system has lost tension. CGI spiral balances in the Estate Series are rated for roughly 10,000 cycles, but Belle Glade’s salt air and humidity corrode the spring housing faster than inland ratings suggest. We replace the balance and the pivot shoe together; installing a new balance on a worn shoe is a callback.
• Visible gap between sash and frame when closed. The weatherstrip has compressed or the sash warped slightly. On impact-rated units, this gap also breaks the pressure seal the interlock needs to perform in a storm. We measure the sightline gap with a feeler gauge; anything over 1/8 inch means the sash or the frame liner needs replacement, not just new pile.
• Crank handle spins without moving the sash. The operator gearbox stripped. CGI uses two operator types depending on year: the earlier nested-arm design and the later scissor-style. The mounting holes differ. We check the casting marks before ordering; forcing the wrong operator cracks the cover plate.
• Condensation between the glass panes. The insulated glass unit (IGU) seal failed. This is not repairable. The IGU gets fabricated to the exact sightline dimension of your sash, then re-glazed. In Belle Glade, we see this most often on west-facing units where daily thermal cycling is hardest on the seal.
• Frame corner weeps staining the sill. The weep holes are blocked or the sill pan is pitched wrong. We flush the drainage path and check the sill angle with a level; CGI specifies 5 degrees minimum pitch, and we have found installs in Belle Glade near the lake where settling dropped that to nearly flat.

Replacement Cost & What’s Included

The range reflects real variables, not a bait-and-switch. Impact-rated work in Belle Glade requires permit pull and inspection; we handle both and include the fee in the written quote. Our price is the measured survey price. The 365-Day Done Right Promise covers the installation and the part; if the new IGU fogs or the balance loses tension inside a year, we replace it under Haven Clause 5.

DIY or Call Us?

There is a safe middle ground. You can check the series mark, clear weep holes with a pipe cleaner, and photograph the part number for us to verify. What we do not recommend: removing an impact-rated sash without support bracing, or attempting to reset an IGU yourself. The glass is heavy, the edge seal is easy to contaminate, and a dropped sash in a second-story opening is a serious fall hazard.

We have replaced CGI windows in Belle Glade homes near McDonald Park where the original aluminum frames had been fighting humidity since the eighties. Measure it right the first time. The frame will not forgive a shortcut, and neither will the next hurricane season. If you are unsure what part you need, call us at (561) 286-4734. We will schedule a measured survey, give you a written price, and if you have a competitor’s estimate already, we will review it free under our Second Opinion policy.
