CGI Window Replacement: The Weston Owner’s Guide

CGI window replacement in Weston typically runs $340-$780 per opening for standard vinyl impact units, with most jobs scheduled within 48 hours of the measured survey. We stock CGI-compatible frames, sashes, and hardware for the most common series in Broward County, and we carry the full catalog for what we don’t have on the truck. Most Weston homeowners discover a CGI window is failing when the sash won’t stay open on its own, the lock bar catches, or they notice daylight between the frame and the jamb after a storm - signs that the balance system, keepers, or the frame itself has shifted in our heat-and-humidity cycle.

Which CGI Models This Applies To

CGI’s product lines have changed naming conventions twice since 2015, so the label inside the jamb is your fastest reference. Look for a sticker on the top of the frame or the edge of the sash with a series code: Sentinel, Estate, or Targa for impact-rated vinyl; Citation or Sparta for earlier non-impact lines still found in Weston homes built 2005-2012. The series name tells us the wall depth (2⅜-inch vs. 3¼-inch), the screen track configuration, and whether the balance is a block-and-tackle or a constant-force coil system.

We match OEM CGI parts where the series is still in production. For discontinued lines, we fabricate from quality aftermarket equivalents that meet the same DP rating and wall depth. One compatibility gotcha we see regularly in Weston: the Estate 4000 series uses a proprietary keeper spacing that aftermarket hardware sometimes misses by ⅛ inch, which is enough to leave the lock bar proud of the frame. We check this against the original sightline measurement before ordering.

We also stock and install replacement parts for PGT, CWS, and ES Windows if your home has mixed manufacturer packages, which is common in Weston subdivisions built during the 2008-2012 period when builders sourced by availability.

Signs Your CGI Window Replacement Is Failing

• Sash drops or won’t stay open. The balance system - either a coil spring or block-and-tackle - has lost tension. In Weston, the salt air accelerates corrosion inside the balance housing, so a five-year balance in Orlando is often a three-year balance here.
• Lock bar won’t engage or requires force. The keeper has shifted on the jamb, or the cam has worn. Heat cycling in south-facing windows causes PVC keepers to creep; we see this most on second-story exposures above the tree line.
• Visible gap between sash and frame, or water intrusion at the sill. The weatherstrip has compressed or the sill track is clogged with debris. On CGI units with weep holes, blocked drainage forces water into the wall cavity instead of out.
• Fog between panes that doesn’t clear. The insulated glass unit (IGU) seal has failed. In Weston, IGUs with inadequate warm-edge spacing typically fail at the southwest corner first due to thermal stress.
• Frame corner separation or visible bowing. The window was likely shimmed incorrectly during original install, or the structural opening has settled. CGI’s welded vinyl frames don’t separate on their own; this is almost always an installation or structural issue.

Replacement Cost & What’s Included

These are installed prices, including removal, disposal, and re-sealing to the opening. What drives the range: wall depth (2⅜-inch vs. 3¼-inch), whether the nailing fin is intact, and whether the interior trim can be preserved. Every quote is written before work starts - Haven Clause 1 - and the measured survey you keep is the same document we build from. The 365-Day Done Right Promise covers the installation and the parts; the manufacturer’s warranty covers the product itself. We document the finished condition with photos, standard on every job.

DIY or Call Us?

There is safe checking, and there is unsafe disassembly. A homeowner can verify the series label, clear weep holes with a pipe cleaner, and confirm whether the lock bar engages smoothly. What we do not recommend: removing a sash with a failed balance, working on second-story units without proper ladder tie-off, or attempting to reglaze an IGU. The balance system is under load; a slipped tool can launch a sash with enough force to break the glass or the hand stopping it.

We are an independent service provider - not affiliated with CGI - and we stock the parts that fail most often in this climate. If you’re unsure of the series or the failure point, call (754) 812-9260 and we’ll walk through what to check before scheduling the measured survey. Measure it right the first time. The window does not care how confident you were.
