CGI Window Replacement Nationwide

CGI Window Replacement: The Los Angeles Owner’s Guide

We stock and install CGI-compatible replacement windows throughout Los Angeles, with most swaps running $850 to $1,900 installed depending on size, series, and glass package. Same-week scheduling is standard for us, and if you’ve got a failed sash, cracked impact glass, or a fogged insulated unit, we can usually match your CGI window the first visit. Most Los Angeles homeowners discover the problem the hard way: a window that won’t stay open, condensation trapped between the panes, or a crack that spidered across the impact glass after one too many Santa Ana wind seasons.

Here’s what you need to know before you spend a dollar: CGI windows are built to the strictest impact standards, which means the components are heavier, the tolerances are tighter, and the wrong replacement part will look close but never sit right. We’d rather you call us with the right information than guess.

Which CGI Models This Applies To

CGI’s residential lineup covers a lot of ground in Los Angeles, from the Estate Collection and Targa series to the Classic and Sentinel lines. Most CGI windows built after 2005 carry a label etched into the glass or stamped on the frame edge near the sash lock: look for the CGI logo, the model series, and a product ID number. That number is the fastest way to confirm exactly what you’re working with.

Here’s the compatibility gotcha that catches a lot of owners off guard: CGI impact windows use proprietary balance systems and corner keys, and the sash dimensions vary by series even when the glass size looks identical. A Targa sash will not swap into an Estate frame without modification, and forcing it is how you end up with a window that binds mid-track. We install OEM CGI components when the series is current and production is active. For older or discontinued series, we source quality aftermarket equivalents that match the original glazing thickness and frame profile. We’re an independent service provider, not affiliated with CGI, which means we’ll tell you straight when OEM is worth the wait and when an equivalent does the job for less.

Signs Your CGI Window Replacement Is Failing

• Fog or haze between the glass panes. The insulated glass unit seal has failed. Once the desiccant inside the spacer bar saturates, there’s no drying it out. The fix is replacement glass, not a window swap in most cases, but Los Angeles humidity swings near the coast accelerate this failure.
• The sash drops or won’t stay raised. CGI windows rely on spiral or block-and-tackle balances sized to the sash weight. When a balance spring fatigues, the window either slams shut or needs both hands to lift. We see this most often on larger picture-adjacent sashes in Silver Lake and Echo Park homes with south-facing exposure.
• A crack in the impact glass that’s spreading. Impact-rated glass can take a hit and hold, but once a crack starts, each thermal cycle pulls it wider. A cracked impact pane has already used its protection; it won’t stop the next flying branch the way it should.
• Water staining at the sill or drywall below the window. This is rarely the glass. It’s usually a failed weatherstrip or a frame corner that’s separated. Left alone in a Los Angeles rainy season, that stain turns into drywall repair and sill rot we have to cut out before we can set the new window.
• The sash binds or scrapes when you open it. Salt air and sun exposure along the coast, plus settlement common in older hillside homes from Mount Washington to the South Bay, slowly twist frames. The window still looks fine from the street, but the track alignment tells a different story.

Replacement Cost & What’s Included

In Los Angeles, a single CGI replacement window runs $850 to $1,900 installed depending on series, glass package, and whether we’re replacing the sash only or the full frame. Here’s the breakdown:

• Sash or component replacement (balances, rollers, weatherstrip): $225 to $550 installed
• Insulated glass unit only, standard impact glass: $400 to $800 installed
• Full window replacement, standard CGI series: $850 to $1,900 installed
• Large or custom Estate Collection windows with upgraded low-E glass: $1,500 to $2,800 installed

Every quote includes the part, labor, disposal of the old sash or glass, and a written price before we start. No change orders, no surprise line items. The work carries our written repair guarantee, and it falls under the 365-Day Done Right Promise: if it’s not right, we make it right, no argument needed.

DIY or Call Us?

You can safely inspect the window from inside: check the glass for cracks, look at the corners for separation, and note whether the sash sits square in the frame. That’s about where safe DIY ends. CGI impact windows are heavy; a full Estate sash can run 40 pounds or more, and the balances are under tension. When a homeowner decides to save money by pulling the sash themselves, the most common result is a broken balance, a torn weatherstrip, or a sash dropped on a tile floor. We’re not saying that to scare you off. We’re telling you what we see when we get the call after the attempt.

Measure it right the first time, or you’ll be measuring it twice and paying for it either way. Call us at (213) 269-5559 and we’ll send someone who knows what they’re looking at.
