Most West Palm Beach homeowners discover they need a CGI window replacement after a rough storm season, when the glass shows stress cracks, the frame won’t seal, or the sash refuses to stay up. Sometimes it’s a broken balance or a failing roller, and other times the entire unit has reached the end of its serviceable life. Salt air, hurricane-force winds, and relentless UV exposure wear down even the toughest CGI products faster here than almost anywhere else in the country.

Which CGI Models This Applies To

CGI manufactures several distinct window lines, and the replacement path differs for each. The Sentinels Series and Estate Collection are common in West Palm Beach homes built or retrofitted after 2005, while older properties may have Tradewinds or discontinued CGI lines that require custom matching. Each series has different frame profiles, glass packages, and hardware, so we always verify the model before ordering parts.

Here’s a practical gotcha we run into all the time: CGI stamps the model number on the frame, not the glass. Look for a label on the inside of the operable sash or along the frame edge, usually a small aluminum plate. If that label is gone or faded (very common after 10-plus years of Florida sun), we measure the frame depth, glass thickness, and corner construction to identify the series. OEM CGI parts make sense for most replacement work, especially if your home is under a current insurance or code compliance requirement. Quality aftermarket equivalents exist for hardware like balances and rollers, but we steer West Palm Beach homeowners toward OEM for glass and frames because the tolerances matter when a Category 3 is approaching.

We also handle replacement parts for PGT and CWS windows, along with ES Windows, if you have a mixed installation. Winslow Windows & Doors is an independent service provider, not affiliated with CGI, but we install their products regularly and know their hardware inside and out.

Signs Your CGI Window Replacement Is Failing

• The window won’t stay up or slams shut. CGI sashes rely on spring balances or friction hardware. When those wear out in the Florida heat and humidity, the sash becomes a danger to fingers and a liability during high winds. We replace balances and get the window operating correctly, often without touching the frame.
• Condensation or haze between the panes. That’s a failed seal on the insulated glass unit (IGU). Once the seal goes, the window loses its energy rating and the glass fogs permanently. In West Palm Beach’s humidity, this shows up as persistent interior moisture or visible mineral deposits on the glass.
• Water stains on the interior sill or drywall. This means the weep system is clogged or the frame seal has degraded. Salt air accelerates frame corrosion, and by the time you see interior staining, the water has likely been working its way in for months. Don’t wait on this one.
• Visible cracks in the glass or frame joints. Hairline cracks in impact glass are a structural failure, not a cosmetic issue. CGI’s laminated glass can hold together even when cracked, but the protective rating drops significantly. Frame cracks at the corners indicate the window has been racked out of square, usually from building settlement or storm stress.
• Windows feel loose or rattle during normal operation. Loose sashes, worn rollers, and failed weatherstripping all point to hardware that’s reached the end of its life. A rattling window isn’t just annoying in West Palm Beach – it’s a leak point for water, air, and eventually everything you don’t want coming through during a storm.

Replacement Cost & What’s Included

For West Palm Beach homeowners, here’s what you can expect to pay for CGI window replacement, installed:

• Glass-only replacement (IGU swap): $450 to $950 per window
• Hardware replacement (balances, rollers, locks): $120 to $380 per window
• Full window replacement (standard sizes): $900 to $1,800 per window
• Full window replacement (oversized or custom CGI models): $1,800 to $2,800 per window

What drives the range? Glass package matters most: clear impact glass costs less than Low-E impact glass with tint. Frame condition matters too. If the original frame is square and solid, a glass or hardware swap keeps the price down. If water damage has rotted the buck or warped the frame, the full replacement is the only honest fix. Every estimate from us is a written line-item quote before work starts, and the price doesn’t change mid-job. We carry a $40 discount on any repair over $200, and if you’ve already got a written estimate from another company, bring it in for a free second opinion. Our workmanship is backed by the Done Right Promise: if we don’t do it right, we come back and make it right.

DIY or Call Us?

Here’s what you can safely check on your own: look for the model number on the frame edge, note whether the glass is cracked or the sash is binding, and open and close every window to see which ones are struggling. That diagnosis is genuinely useful and helps us arrive with the right parts.

What you shouldn’t do is pull the sash apart on an impact window. CGI windows are built differently than standard residential windows, and the tension in the balances and the way the laminated glass seats in the frame means a wrong move can lead to shattered glass or a window that’s worse off than before. The weight of a CGI impact sash isn’t like a normal window either, and if it drops on your hand, you’re looking at broken bones. We bring the right parts, the right tools, and a background-checked technician in uniform who knows this exact window line. Call us at (561) 660-9539 and we’ll get you sorted out.
