CGI Window Installation: The West Palm Beach Owner’s Guide

CGI window installation in West Palm Beach typically runs $340-$780 per opening for standard replacement, depending on series, impact rating, and whether the frame needs re-anchoring to Florida Product Approval standards. We stock CGI-compatible hardware and anchoring systems on our trucks, and most replacements we measure in the morning are installed by afternoon. The call usually starts with a homeowner noticing the sash won’t stay open, or finding water at the sill after a storm that never leaked before.

Which CGI Models This Applies To

CGI manufactures under several series names, and the part you need depends on which line is in your wall. The Estate Series uses a heavier-duty balance system and 2-1/4 inch frame depth, while the Sentinel Series runs a slimmer 2-inch profile with a different corner key geometry. The Targa Series, common on West Palm Beach homes built between 2015 and 2020, carries a distinct label inside the head jamb: a silver sticker with the CGI logo and a six-digit lot number starting with “T-” or “ES-“.

We also see the WinGuard and WinGuard Vinyl lines in older installations near Flagler Drive and the El Cid historic district, where the original builder spec’d CGI for impact compliance. The balance shoes on these older vinyl units are not interchangeable with the Estate aluminum line, even when the sash dimensions match. We carry both OEM CGI replacement hardware and verified aftermarket equivalents from Truth Hardware and Caldwell, selected by what your specific series requires, not by what costs us less.

One compatibility gotcha we catch regularly: the Estate Series 2100 and 2300 look identical from the interior until you remove the stop and measure the balance tube. The 2300 uses a 5/8 inch diameter tube; the 2100 uses 9/16. Order the wrong one and you’re cutting drywall to extract a balance that doesn’t fit the bracket.

Signs Your CGI Window Installation Is Failing

• Sash drops or won’t stay open. The coil balance has lost tension, usually from corrosion at the pivot bar connection. In West Palm Beach, salt air accelerates this; we see it first on east-facing units within seven years of install.
• Water intrusion at the sill after rain. The weep system is blocked or the sill flashing was never sealed to the subsill during original installation. CGI units have two weep channels; both need to be clear, and the subsill must be bedded in sealant, not just screwed down.
• Condensation between panes. The insulated glass unit (IGU) seal has failed. This is not a frame problem; it’s a glazing problem, but the IGU must be ordered to CGI’s exact sightline dimensions or the replacement won’t seat in the sash.
• Difficulty locking or unlocking. The keeper has shifted due to frame racking, or the lock mechanism itself has corroded. On impact-rated units, the lock is part of the pressure rating; a sticky lock is a failed lock in code terms.
• Visible frame separation at corners. The splice keys have backed out or the thermal break adhesive has degraded. This is structural; the frame is no longer performing as a unit and will leak under wind load.

Replacement Cost & What’s Included

For a standard CGI window replacement in West Palm Beach, here is what we see on our written quotes:

The range depends on three things: whether the existing frame can be reused, whether the opening needs re-flashing to current code, and whether we discover rot in the rough opening once the old unit is out. We find that last issue more often than you’d expect in West Palm Beach, particularly in pre-1990 construction near the Intracoastal where original builders used untreated wood bucks.

Every quote is the measured survey you keep. The price on that document is the price on the invoice. If the number isn’t on the page, it isn’t in the price. Work carries our 365-Day Done Right Promise under the Haven Standard, and you receive the documented photo record before we leave.

DIY or Call Us?

There is one thing a homeowner can safely check: the weep holes. Run a piece of wire or a pipe cleaner through the exterior channels at the sill. If water drains out, the weep system was blocked. If it doesn’t, the problem is likely behind the frame.

Everything else on a CGI window carries risk that outweighs the savings. Impact-rated units are tested as complete assemblies; replace one component with a non-rated equivalent and the opening no longer meets the Miami-Dade or Florida Product Approval that your insurance and code compliance depend on. Balance systems are under spring tension; a coil balance can unwind with enough force to lacerate a hand or launch a pivot bar across the room. And the frame anchoring on impact units is spec’d to a torque value and pattern that a homeowner has no way to verify.

We are not affiliated with CGI. We are an independent service provider that installs and services their products to factory specification. If you’re holding a failed balance, a fogged IGU, or a frame that has shifted in its opening, call (561) 354-3861. We’ll measure, write the price, and show you exactly what we found.
