CGI Window Replacement Nationwide

CGI Window Replacement: The San Antonio Owner’s Guide

CGI window replacement in San Antonio typically runs $450 – $1,200 per window installed, depending on the series, glass package, and whether the frame itself is still sound. We keep CGI-compatible sashes, balances, rollers, and glass units in stock for most CGI Estate, Sentry, and Classic series windows, and we can usually complete a single-window swap the same day we diagnose it. Most San Antonio homeowners discover they need this work after a crank handle strips out, a sash drops hard when opened, or a south-facing window starts showing condensation between the two glass panes that won’t wipe away.

That last one is the tell. A failed insulated glass unit doesn’t just fog up, it quietly loses the argon or krypton gas that was doing the insulating. In San Antonio’s July heat, that turns a sealed window into a radiator above your sofa. Spencer Odell has pulled enough failed panes out of Cibolo and Stone Oak homes to know exactly what that costs you on your CPS bill.

Which CGI Models This Applies To

CGI’s San Antonio market is dominated by three series: the Estate line, the Sentry line, and the Classic aluminum single-hung. Each takes different replacement parts, and here’s the compatibility gotcha most homeowners hit: a Sentry sash will not seat correctly in an Estate frame even if the visible dimensions match within an eighth of an inch. The interlock profile where the upper and lower sash meet is cut differently. If you order a replacement sash from a generic supplier that isn’t matching by CGI’s actual part code, you’ll get something that looks close and binds the second it goes in.

The correct way to identify your part is the white rectangular label inside the frame track, visible when you tilt the sash in. CGI stamps the series name, the glass package code, and the date of manufacture right there. If that label is gone or unreadable, we can pull the sash and read the etched code on the glass spacer bar. For glass replacement specifically, OEM (CGI-branded) units preserve your original warranty terms on the window itself. Quality aftermarket equivalents run 20 – 30% less and use identical double-strength glass and low-E coatings, but they reset the warranty picture. We give you both prices in writing and let you choose.

CGI’s San Antonio footprint also includes coastal-rated units originally sold for storm zones. If your home is on the far north side around Bulverde Road, you probably don’t need a Dade County-rated replacement unit. We won’t upsell you one either. But if your window label shows a DP-50 rating or higher, we won’t downgrade it.

Signs Your CGI Window Replacement Is Failing

• Condensation between the panes that won’t wipe off. This means the perimeter seal on the insulated glass unit has failed. The desiccant inside the spacer bar is now saturated, and no amount of Texas sun will dry it out. The glass package is dead; replacement is the fix.
• A sash that sags, drops, or won’t stay up. CGI balances use spring-loaded or block-and-tackle systems that lose tension faster in extreme heat. A window that slams shut when you let go isn’t just annoying, it’s a finger injury waiting for a kid. This is a safety issue.
• A crank or handle that spins without engaging. The gear teeth inside CGI casement operators are zinc alloy and strip over time. When you turn the crank and nothing moves, the operator needs replacement, not just the handle.
• Visible frame rot or soft wood around the sill. This is more common on the exterior frame where San Antonio’s heavy rain seasons meet decades of sprinkler overspray. A window replacement that only swaps the sash while the frame rots underneath is throwing money away.
• Air you can feel around the sash edges on a windy day. Weatherstripping on CGI windows compresses and degrades in high UV. If you can feel a draft with the window locked, the seal between sash and frame is gone.

Replacement Cost & What’s Included

Here’s what we charge in San Antonio, in plain numbers, so you know before you call:

• Insulated glass unit replacement (per sash): $180 – $340 installed. Depends on glass size, low-E coating level, and whether you want OEM or aftermarket glass.
• Full sash replacement (Estate or Sentry): $380 – $700 installed. This covers a new sash with glass, new balances, and new weatherstripping, fitted to the existing frame.
• Full window replacement with frame removal: $700 – $1,200 per opening. This is the right call when the frame itself has rot, racking, or failed flashing. New construction-grade CGI or a comparable PGT, CWS, or ES Windows unit goes in.

Every one of these prices is a written quote you receive before we pick up a tool. No change orders, no “we found additional work” surprises on the invoice. Every replacement carries our written guarantee, and the job falls under our 365-Day Done Right Promise. If it’s not right, we make it right. That’s not a marketing line, it’s the document we hand you with your receipt.

For a full-frame replacement, permits are pulled when San Antonio code requires them, and we handle the inspection. For sash and glass swaps, no permit is needed and we usually finish in under two hours.

DIY or Call Us?

Some parts of this job are safe for a careful homeowner. You can clean and lubricate a sticky track with dry silicone spray. You can replace a lift handle or a lock mechanism with basic tools. You can even swap a snap-in glazing bead for a new one if you’re patient.

What we’d tell you not to do is handle the spring-loaded balances yourself. CGI balance systems hold real tension. If a block-and-tackle balance releases while you’re prying it out of the jamb, the spring can drive a plastic connector into your hand fast enough to break bone. We’ve seen it. Same goes for hoisting a large glass unit overhead. A double-glazed sash for a picture window can weigh 70 pounds. A fall from a ladder onto tile isn’t worth the couple hundred you save.

If the problem is fogged glass or a dead balance, call us at (361) 348-8929. We’ll tell you over the phone what you’re likely looking at, then send a technician to confirm with a written price before any work starts.
