CGI Window Replacement Nationwide

CGI Window Replacement: The Fort Worth Owner’s Guide

CGI window replacement in Fort Worth typically runs $400 to $1,100 per window installed, depending on the CGI series, glass package, and whether the frame needs full replacement or the sash alone can be swapped. We stock CGI-compatible sashes, balances, seals, and hardware on our trucks, and in most cases we can complete the replacement the same visit we diagnose the problem. Most Fort Worth homeowners discover a CGI part has failed the hard way: a window that suddenly won’t stay up, a latch that no longer catches, fog between the panes after a spring hail storm, or a frame that’s started letting North Texas dust through a gap that wasn’t there last season.

If you’ve got a CGI window that’s acting up, you’re in the right place. Below we walk through which models this applies to, what actually fails on CGI windows in this climate, what an honest installed price looks like, and whether you should grab a screwdriver or pick up the phone.

Which CGI Models This Applies To

CGI builds impact-rated windows and doors, and the replacement parts we handle most in Fort Worth come from the Estate Collection, Sentinel Series, and CGI Classic line. These share hardware platforms across several model years, but there’s a compatibility gotcha worth knowing: CGI changed its balance shoe design around 2017, and the older shoe will not seat correctly in a newer frame without a retrofit clip. If your window was installed before 2017, we bring the retrofit clip as a matter of course to avoid a second trip.

To identify your CGI window, look for the silver CGI label on the frame edge or inside the track near the sill. It’ll show the series name and a manufacturing code we can use to confirm the part before we touch anything. For the glass itself, CGI uses laminated impact glass that’s thicker than standard builder-grade material, so a sash from another brand won’t seat properly even if the rough dimensions line up. We recommend OEM CGI parts for load-bearing components like balance systems and impact glass; for cosmetic trim and weatherstripping, a quality aftermarket equivalent often performs identically and costs less. Either way, we’ll tell you the difference and quote both when it makes sense.

As an independent service provider, we’re not affiliated with CGI. What we are is a Fort Worth window company that’s stocked and installed their product lines for years, and we know which parts interchange and which don’t.

Signs Your CGI Window Replacement Is Failing

• Window drops or slams shut when you raise it. This is almost always a failed balance system. On CGI units, the constant heat cycling in Tarrant County attics and walls breaks down the nylon shoe bearings faster than the manufacturer’s average lifespan estimate, and once the shoe cracks, there’s nothing holding tension.
• Fog or moisture between the panes. That’s a failed seal on the insulated glass unit. Fort Worth’s swing between humid springs and 100-degree summers stresses perimeter seals, and once argon leaks out and moisture gets in, the glass needs replacement, not a repair.
• Latch or lock won’t catch. Frame settlement and repeated slamming wear the keeper plate or misalign the sash. On CGI impact windows, a latch that doesn’t seat means the window isn’t doing its storm job either, which matters when the next hail line rolls through.
• Visible daylight at the meeting rail or sill. Worn weatherstripping or a warped sash. You’ll feel the draft first in January, but you’ll see the dust line in July. That gap also lets in the fine clay dust Fort Worth is famous for.
• Crank or slider requires real muscle to move. Dirty or failed rollers on sliders, stripped gear teeth on casement cranks. The CGI roller assemblies are solid, but the dry Texas grit that gets into the track acts like sandpaper over time.

Replacement Cost & What’s Included

Here’s what Fort Worth owners can expect to pay for common CGI window replacement work, installed:

• Balance system replacement: $120 – $260 per window, including parts and labor
• Sash replacement (matching CGI series): $350 – $700 per window
• Insulated glass unit replacement: $400 – $900 per window, depending on impact rating and size
• Hardware rebuild (latch, keeper, weatherstripping, rollers): $150 – $400 per window
• Full frame replacement with new CGI window: $800 – $1,800 per opening, installed

The range comes down to the series, whether the glass is standard insulated or laminated impact, and whether the existing frame is square enough to accept a sash swap instead of a full pull. Every quote we give is a written line-item price before any work starts, and it includes the part, the labor, haul-off of the old material, and a 365-day warranty on parts and labor under our Done Right Promise. No change orders. No “we found something once we opened the wall.” Sean Mackey has been clear with his crew since day one: get the numbers right up front, and the install takes care of itself.

DIY or Call Us?

There are things you can safely do and things you shouldn’t. Reading the CGI label on your frame and snapping a photo to help us identify the part? Absolutely do that. Replacing a sash or balance system on an impact-rated window? That’s where we’d stop you. Tensioned balance springs carry enough stored force to injure you if released wrong, and a mis-seated impact sash means the window won’t perform in a storm, which is the reason you bought CGI in the first place. By the time you’ve bought the specialty tools and the right OEM part, you’re often close to our installed price anyway. Call (682) 354-9300 and we’ll diagnose it, quote it in writing, and install it right the first time.
