CGI Window Installation: The Stuart Owner’s Guide
CGI window installation in Stuart typically runs $850 to $2,400 per opening installed, depending on the series, size, and whether you’re replacing a failed unit or installing new impact glass. Most CGI replacement work we do is completed in a single visit. Homeowners usually find us the same way: a seal has fogged, a sash has started binding in the frame, or a storm rolled through and a window that was supposed to be impact-rated didn’t hold up the way the sticker on the glass said it would. That’s the moment the paperwork matters as much as the glass.
We stock and install CGI-compatible window units across Stuart, Jensen Beach, Palm City, and the surrounding Martin County area. TruePane Windows & Doors is an independent installer and service provider, not a division of or affiliate of CGI. That independence means we quote your options side by side on paper and let the numbers and specs do the talking.
Key Takeaways
- CGI window installation in Stuart runs $850 to $2,400 per opening, parts and labor included
- Identifying your CGI series correctly before you buy saves you from a return trip and a restocking fee
- Aftermarket glazing beads and balance shoes are fine; aftermarket glass packs void the warranty
- We carry common CGI hardware on the truck and can source series-specific parts same week
Which CGI Models This Applies To
CGI builds its window lines in series: Estate, Sentinel, Targa, and the commercial-grade CGI Commercial line. Each series has different frame depths, glazing bead profiles, and balance systems. The number that matters is stamped on a small metal or foil label on the inside edge of the sash or the head jamb. Look for a code that starts with the series name followed by a four- to six-digit production sequence. If the label is gone, which we see regularly on Stuart homes where salt air has worked on the foil, we match by measuring the glass pack thickness and the frame depth with a caliper.
Here’s the compatibility gotcha most owners run into: CGI’s Estate and Sentinel series use a proprietary glazing bead that aftermarket suppliers do not reliably reproduce. We have seen homeowners order a “CGI-compatible” bead online, only to find it seats a sixteenth of an inch proud and leaks air at the first hard rain. For glass packs, the decision matters more. OEM CGI glass carries the laminated impact rating and the warranty registration. Aftermarket glass, even when it fits, does not carry the impact certification. In Stuart, where code enforcement checks impact ratings on permits, that distinction matters. We stock common CGI hardware including balance shoes, pivot bars, sash locks, and weatherstripping on our trucks. Series-specific extrusions we order direct and usually have within a week.
Signs Your CGI Window Installation Is Failing
- Fog between the panes: The desiccant in the spacer bar has saturated, usually after ten to fifteen years of Treasure Coast humidity. The seal is done; the glass pack needs replacing, not drying out.
- Sash binds when you open or close it: This is typically a worn balance shoe or a frame that settled out of square. In Stuart, slab homes on sandy soil shift enough over two decades to pinch a sash that once glided.
- Water staining on the interior sill after heavy rain: The weep holes at the bottom of the outer frame are clogged with salt crust or debris, or the original install left the sill flashing short. We see this most often on east-facing windows that take the full force of summer squalls.
- You can hear road noise more than you used to: The weatherstripping has compressed or the corner gaskets have dried out. A $40 weatherstrip kit restores the seal if the frame is still square; if the frame is racked, the weatherstrip is a band-aid.
- The crank operator slips or spins free: The gear teeth inside the operator body have stripped, usually from forcing the sash against a warped frame. The operator is replaceable, but the warped frame is the root problem; replacing the hardware without correcting the frame means you’ll do the job again in two years.
Replacement Cost & What’s Included
For a standard CGI single-hung or casement unit in Stuart, expect to pay $850 to $1,600 per opening for the glass pack and installation. Larger fixed picture windows and custom sizes run $1,400 to $2,400. If the frame extrusion itself is damaged or badly out of square, add $300 to $700 per opening for frame work. These are installed prices: the part, the labor, the sealant rated for coastal exposure, and the haul-off of the old glass.
| Scope | Installed Price Range (Stuart) |
|---|---|
| Standard CGI single-hung replacement (glass pack + labor) | $850-$1,400 |
| CGI casement unit replacement | $950-$1,600 |
| Large fixed or custom CGI window | $1,400-$2,400 |
| Frame repair or squared reset per opening | $300-$700 |
| Hardware-only repair (balance, lock, operator) | $140-$320 |

DIY or Call Us?
There are things worth checking yourself. If a sash feels stiff, clean the track with a dry brush and check the weep holes are clear of sand and salt crust. If you can see daylight around the weatherstripping, a replacement strip is a reasonable weekend job on a single-story window. What we would not do yourself is anything involving the glass pack, the balance springs, or the frame. A CGI impact-rated glass pack in Stuart runs 60 to 100 pounds depending on the unit. If it drops out of the frame while you are easing it free, the injury is serious and the glass is not cheap to replace. The balance springs are under enough tension to take a fingertip off. If the frame is out of square, you cannot shim it true from inside the house without pulling the interior casing, and half-measures there just move the stress to the new glass.
Dale Kessler grew up in Rio, just south of Stuart along the St. Lucie River, and spent years learning the trade from his father before opening TruePane. One of his rules, the one he uses on every job, is this: if the opening is right, the rest is just doing the work. We measure every opening twice, and if the frame is out of square, we tell you before we quote you. Call (754) 324-4646 and we will come take a look.
FAQs
A CGI impact window in Stuart’s salt-air, high-UV climate should deliver 15 to 20 years of service before the seal or hardware starts to go. Coastal exposure, especially within a mile of the Atlantic or the St. Lucie River, shortens that by a few years compared to inland Palm City. The glass pack typically fails before the frame. Call (754) 324-4646 if you’re seeing fog or binding.
No. Once the seal between the panes has failed and moisture has entered, the desiccant inside the spacer bar is saturated and the glass pack needs replacement. There are companies that drill and vent fogged glass; we do not do it because the fix does not hold, especially not in Stuart humidity. The honest solution is a new glass pack.
Most single-unit CGI replacements in Stuart are completed in one day, and if the balance hardware or operators are on our truck, we can usually finish in a few hours. Multiple windows may take two days if the frames need squaring or the sizes are custom. We’ll give you a written timeline at the estimate, and we’ll be there when we say.
We stock common CGI hardware including balance shoes, pivot bars, sash locks, keepers, and weatherstripping on our trucks. Glass packs are ordered to the exact size and series from CGI or an approved supplier; that usually takes under a week. Call (754) 324-4646 with your series name and we’ll tell you what’s available and when it lands.
