CGI Window Replacement: The Sunrise Owner’s Guide

CGI window replacement in Sunrise typically runs $340-$780 per opening installed, depending on the series, glazing package, and whether the frame is preserved or replaced entirely. We stock CGI-compatible sashes, balances, and hardware for same-day replacement on most residential series, and we carry the full CGI catalog for full-unit swaps when the frame has failed. Most Sunrise owners discover the problem when a window won’t stay open, won’t lock, or shows daylight between sash and frame after a storm season.

Which CGI Models This Applies To

CGI manufactures three residential lines you’ll find across Sunrise: the Estate Series (aluminum impact-rated), the Sentinel Series (vinyl impact-rated), and the commercial-grade Targa line. The Estate 200 and 400 series dominate the single-family stock in neighborhoods like Sawgrass Estates and Welleby, where most homes were built between 2004 and 2018 with original CGI units.

To identify your exact part, check the etched mark on the glass spacer or the sticker inside the frame jamb. It will read something like “Estate 250 SH” or “Sentinel 3120.” The critical compatibility gotcha: CGI revised its sash lock geometry in 2019, so a post-2019 Estate lock barrel will not seat in a pre-2019 keeper without replacing both components. We verify this on the measured survey before ordering.

We source OEM CGI parts through the manufacturer’s Florida distribution center in Medley. For discontinued series like the early Targa 1000, we fabricate equivalent sashes from stock extrusions that match the original wind-load rating and sightline dimension. Sightline Windows & Doors Sunrise is an independent service provider, not affiliated with CGI.

Signs Your CGI Window Window Replacement Is Failing

• The sash drops or won’t stay raised. This is almost always a failed balance system. CGI’s spiral balances in the Estate series carry a 10-year rated lifespan in coastal Florida, but we’ve found they typically show fatigue at 7-9 years due to salt air exposure in Sunrise’s inland-but-humid climate. The balance loses tension gradually; owners prop the window open before they call.
• Visible moisture between the glass panes. The insulated glass unit (IGU) seal has failed. In Broward County, this accelerates when the frame weep channels clog with debris after heavy rains, trapping water against the spacer. The IGU must be replaced; defogging sprays do not restore the argon fill or the structural seal.
• The lock engages but the sash still rattles. The keeper has wallowed out or the sash has settled on a worn balance, throwing the tilt out of square. This misalignment stresses the lock mechanism and will eventually crack the lock housing.
• Daylight visible at the sash-to-frame meeting rail. The weatherstrip has compressed past recovery or the sash itself has bowed from thermal cycling. CGI’s black TPV weatherstrip in pre-2016 units is particularly prone to this in south-facing exposures.
• Difficulty rolling or sliding a horizontal unit. The tandem roller assembly has flat-spotted or the track has accumulated aluminum oxide. In CGI sliding windows, the roller axle is a wear item; when it seizes, owners force the sash and distort the frame.

Replacement Cost & What’s Included

The range reflects three variables: whether the existing frame is square within 1/8 inch (if not, we rebuild the rough opening), whether the replacement requires impact-rated glazing per the 2023 Florida Building Code, and whether the HOA in your Sunrise community requires a specific finish or grid pattern. Haven Clause 1 applies: the written quote you receive after our measured survey is the document we install against. No change orders. The 365-Day Done Right Promise covers labor and installation materials; OEM parts carry the manufacturer’s warranty.

DIY or Call Us?

An owner can safely check three things: verify the model stamp inside the frame, confirm the symptom happens on both the top and bottom sash (isolating balance from lock failure), and clear weep holes with a pipe cleaner. Do not attempt to remove a sash supported by a failed balance; the sudden drop can pinch fingers or shatter the IGU if the tilt latch releases unexpectedly.

Where DIY goes wrong: spiral balances store significant tension and require a winding tool specific to the tube diameter. CGI’s Estate series uses a 3/8-inch tube with a left-hand wind on the left jamb, right-hand on the right; reversing this destroys the balance in the first operation. We carry the correct winding tools and the torque specification chart for every CGI series year. For IGU replacement, the sash must be disassembled on a flat surface with proper blocking; we’ve corrected three homeowner attempts this year in Sunrise alone where the glass shifted during re-glazing and chipped at the edge.
