CGI Window Replacement Nationwide

CGI Window Replacement: The Fort Worth Owner’s Guide

We stock and install CGI-compatible window replacements throughout Fort Worth, with most single-window replacements running between $450 and $1,150 fully installed depending on the series, glass package, and frame condition. If your CGI window has a cracked sash, failed seal, or hardware that no longer locks, we can usually match the replacement part from our truck stock or have it sourced within three to five business days. Most Fort Worth homeowners discover a problem the same way: a room that suddenly feels drafty in July, condensation that won’t wipe away between the panes, or a crank handle that spins without moving the sash.

A quick note before we go further: Lightwell Windows Fort Worth is an independent service provider. We are not affiliated with CGI, but we have worked with their product lines long enough to know which replacement parts fit which series, and which failures are worth repairing versus replacing outright.

Which CGI Models This Applies To

CGI builds impact-rated and non-impact window lines, and the replacement path depends on which one you have. The most common CGI series we see in Fort Worth homes are the Estate Collection, the Sentinel line, and the Classic sliders. Each has different sash thicknesses, balance systems, and hardware profiles, so the first thing we do on a service call is read the AAMA label etched into the corner of the glass or the frame sticker on the head jamb. That label gives us the series, the glass make-up, and the manufacturing date, which tells us whether we are matching an OEM part or a quality aftermarket equivalent.

One compatibility gotcha specific to CGI: the balance shoe and pivot bar on their hung windows changed profile around 2016. A pre-2016 sash will not seat correctly into a post-2016 balance shoe even if the visible dimensions look close. We carry both profiles on the truck because getting this wrong means a window that won’t stay up, and that is exactly the kind of detail Keith Yamada checks before he ever quotes a number. For impact-rated CGI units, we always recommend OEM glass replacement rather than aftermarket glazing, since the laminate interlayer and seal specs are part of the wind-missile rating. On non-impact units, a quality aftermarket insulated glass unit with a matching Low-E coating performs just as well and often saves $80 to $150 per sash.

Signs Your CGI Window Replacement Is Failing

• Condensation or haze between the glass panes. This means the seal around the insulated glass unit has given out. The desiccant inside the spacer bar can only absorb so much moisture, and once it is saturated, the fog is permanent. In Fort Worth humidity, a failed seal shows up fast after a rainy spring.
• A sash that drops when you raise it. The balance springs inside the side jambs have lost tension or the balance shoe has cracked. This is a wear item on any hung window, but Texas heat accelerates it because the vinyl components get brittle after repeated expansion and contraction.
• Hard to lock or the lock misses the keeper. When a window frame shifts out of square, the locking points no longer align. Fort Worth’s clay soil expands and contracts with moisture, and older homes with pier foundations see this more than slab homes. Sometimes shimming fixes it; other times the sash is warped and needs replacement.
• Visible cracks in the sash corners or frame welds. CGI vinyl sashes are welded at the corners, and a crack there means the structural seal is failing. You can patch it, but the patch will not hold in a window that cycles open and closed daily.
• Water staining on the interior wall below the window. This points to a failure in the sill flashing or the weep system, not the glass itself. On CGI horizontal sliders, the weep holes along the bottom track can clog with dust and pollen, and water backs up into the frame. A replacement sill track or a full frame replacement may be the fix.

Replacement Cost & What’s Included

In Fort Worth, a CGI sash replacement runs $250 to $550 for a standard double-hung or slider sash with matching Low-E glass. Full window unit replacement, including frame and trim, typically lands between $650 and $1,150 per opening depending on size, impact rating, and whether we are matching existing interior trim or installing new. The spread comes down to three things: whether the unit is impact-rated, whether the opening needs new flashing or sill repair, and whether the existing trim can be reused without visible gaps.

Every quote we give in Fort Worth is a written line-item price before any work starts. You’ll see the part, the labor, and any disposal or trim line separately. There is no allowance for a surprise change order at the end. The workmanship is covered by our 365-Day Done Right Promise: if something about the finished install is not right, we make it right. No debate, no countdown.

DIY or Call Us?

There are a couple of things a Fort Worth homeowner can safely check before calling. You can read the label on the frame to confirm the CGI series, take a measurement of the visible glass width and height, and look for obvious cracks or gaps. That information helps us bring the right part on the first trip.

What we do not recommend is trying to remove a sash or replace a balance spring on your own, especially on a second-story window. The springs in CGI hung windows are under tension even with the sash removed, and a slipped tool can take a finger off. Vinyl sashes also flex, and carrying a large one down a ladder alone is how trim gets gouged and frames get dropped. If you are not sure whether the problem is the sash, the balance, or the frame itself, call (682) 900-6694 and we will send a background-checked technician to look. The diagnostic visit is straightforward, and you will get a written price before we touch anything.
