CGI Window Replacement: The Los Angeles Owner’s Guide

CGI window replacement in Los Angeles typically runs $850 to $1,900 installed per window, depending on the series and glass package. We stock CGI-compatible sashes, balances, rollers, and weatherstripping at Juniper Windows & Doors, and most replacements are done in a single visit. The usual way homeowners discover the problem: a window that suddenly won’t stay up, a sash that feels like it’s grinding against the frame, or a room that starts smelling like a parking garage after rain.

CGI builds windows to a standard most brands in California don’t bother with. The company’s original market was coastal Florida, so its frames are thicker, the extrusions run heavier, and the hardware is engineered to take a beating. That’s great for Los Angeles hillsides where the Santa Anas turn every loose window into a wind chime. The catch is that CGI parts are not universal. A balance from a Home Depot display aisle will not fit a CGI Window 6800 series. We order the right part the first time.

Which CGI Models This Applies To

We replace parts across the CGI window line most commonly installed in Los Angeles: the Estate Collection, the Classic Collection, and the 6800/6900 architectural series. For older homes, we frequently see the now-discontinued Sentinel series, which shares some hardware with the Classic line but not all of it. If your window has a metal label sticker on the upper track or the side jamb, that sticker tells us the series, the glass package, and the manufacturing date. If the sticker is gone (sun does that), we match by measuring the sash profile and the shoe size at the bottom corners.

The OEM-versus-aftermarket question matters more with CGI than with other brands. CGI’s own replacement parts are mil-spec on the aluminum and coated for salt exposure, which is why so many Los Angeles beach neighborhoods from Playa del Rey to San Pedro have CGI windows still functioning after fifteen years of marine air. Quality aftermarket equivalents exist for balances and weatherstripping, and we stock those when they match or beat the original spec. But for any locking mechanism, roller assembly, or corner key on an impact-rated frame, we won’t fit a knockoff. The tolerances are too tight, and the failure point becomes the part the homeowner was trying to save $40 on.

Signs Your CGI Window Replacement Is Failing

• Window drops or won’t stay open. The balance system has lost tension or the shoes have worn. On CGI windows, this is almost always the spiral balance or block-and-tackle setup, and you’ll feel the sash get heavier over about six months before it fails completely.
• Sash tilts or binds when sliding. Los Angeles dust is fine enough to work its way into the roller tracks, and once the rollers get grit in the bearings, the window starts to drag. CGI’s wider frame tolerances mean the roller wheels are the first thing to wear, not the track.
• Air or water coming through a closed window. The weatherstripping has compressed or the interlock at the meeting rail has worn. In Westside homes near the ocean, salt air speeds this up noticeably, and the first sign is usually a faint whistle on windy nights in neighborhoods like Brentwood or Pacific Palisades.
• Lock or latch won’t engage. The keeper has drifted out of alignment or the latch spring is shot. On CGI’s multi-point locks, this is a two-part system, and replacing only the latch side leaves you with a window that closes but won’t seal.
• Visible corrosion or pitting on the frame. Los Angeles sits in a dry climate, so frame corrosion is less common than in Florida. But within three miles of the coast, and in any home with a pool within fifteen feet of the window, we see pitting on the anodized finish. That pitting will eventually compromise the weather seal and the sash alignment.

Replacement Cost & What’s Included

Here’s what we’re quoting for CGI window replacement work in Los Angeles right now:

• Balance replacement (single sash): $120 to $260 per window, parts and labor
• Roller assembly replacement: $140 to $290 per window
• Weatherstripping replacement (full perimeter): $95 to $210 per window
• Lock or latch replacement (single point): $110 to $240
• Multi-point lock replacement: $240 to $520
• Full sash replacement (glass included): $650 to $1,900 depending on series and glass package

Every quote is a written line-item price before any work starts. No estimate that “adjusts” at the door. The 365-Day Done Right Promise covers parts and labor for a full year after the install. If the balance we installed loses tension in month nine, we’re back out and fixing it free. That’s in writing, every job.

DIY or Call Us?

Here’s the honest split. You can safely clean the tracks on a CGI window, check that the weep holes at the bottom of the frame are clear, and visually confirm whether a roller has lost its wheel. Those are maintenance tasks, not repairs, and they prevent a lot of problems in Los Angeles dust.

What you should not do is attempt to replace a spiral balance on a CGI window yourself. Those balances are under tension, and when that tension releases suddenly, it can take off a chunk of finger or ruin the frame. The same goes for any sash-removal job on a second-story window with an impact-rated sash that weighs forty pounds or more. We’ve had more than one Los Angeles homeowner call us after a YouTube attempt went sideways, and the repair bill was always higher than the original fix would have been. Call us at (682) 281-2168 and we’ll get it done once.
