CGI Window Replacement: The Coral Gables Owner’s Guide
CGI window replacement in Coral Gables typically runs $850 to $2,400 per window installed, depending on the series, size, and whether the frame is salvageable. We stock CGI-compatible replacement windows, sashes, and hardware in our Coral Gables service area and can often complete a single-window swap the same day once measurements are confirmed. Most homeowners discover the problem the same way: a window that suddenly takes two hands to crank, a latch that will not seat, or a fogged pane that will not clear in a Coral Gables afternoon storm.
CGI builds windows to Miami-Dade product approval standards, which means a failed part is rarely a cheap off-the-shelf fix. The parts are specific, the tolerances are tight, and the paperwork matters. We have been matching CGI components to the right model for years, and we keep the most common replacement parts on hand.
Which CGI Models This Applies To
CGI’s most common lines in Coral Gables homes are the Sentinel, Estate, and Targa series, along with older Custom Window and Commercial Window units still holding up in mid-century Gables houses. Each series uses different frame depths, sash profiles, and hardware mounting patterns, so a latch from a Sentinel will not necessarily seat in a Targa, even if the window size looks identical. The quickest way to identify your CGI window is the silver product label on the interior frame, usually on the top or side jamb. That label carries the model number, glass make-up, and the crucial Miami-Dade County Notice of Acceptance number. Take a photo of it before you call anyone.
When a CGI window needs replacement, you have two paths: a new OEM CGI unit through the manufacturer’s replacement channel, or a quality aftermarket sash or insulated glass unit matched to CGI’s exact frame profile. We quote both options side by side on paper, because sometimes the OEM unit is the only sensible choice and sometimes a matched IG unit with the same impact rating does the job for less. The decision should be in writing with the spec called out, not explained over the phone in general terms.
TruePane Windows & Doors is an independent service provider. We are not affiliated with CGI. We install and service CGI windows because Coral Gables has thousands of them, and our customers deserve a company that knows the product without waiting on a manufacturer’s schedule.
Signs Your CGI Window Replacement Is Failing
- Condensation between the glass panes. This is a failed seal, and it is the most common reason Coral Gables homeowners call us. The trapped moisture fogs the glass, and no amount of Florida sun will clear it. Once the desiccant inside the insulated glass unit is saturated, the pane needs replacement, not drying out.
- Rust staining or peeling on the interior sash corners. CGI frames are aluminum, and coastal air finds any cut edge or worn finish. Left alone, corrosion spreads into the corner keys and weakens the sash. What starts as a cosmetic blemish becomes a structural problem within a few seasons.
- A crank, handle, or lock that grinds or slips. CGI hardware is built for impact cycles, but salt air and years of operation wear the gears and strike plates. If the handle turns without engaging, the gearbox is shot. If the lock will not throw, the sash has likely settled out of square.
- Visible gaps at the weatherstripping or a window that rattles in wind. Coral Gables gets real wind, and an impact window that rattles means the compression seals have flattened or the sash has sagged. The glass may still be intact, but the listed pressure rating depends on a tight frame seal. A rattling CGI window is not doing its job.
- Hard operation after a storm or settling. If a window opened fine in March and binds in August, the frame has moved. In Coral Gables, the combination of clay-heavy soil, seasonal moisture swings, and older homes on slab foundations means frames shift. Sometimes the fix is a sash adjustment; sometimes the window unit itself needs replacing to match the new frame alignment.
Replacement Cost & What’s Included
For Coral Gables homes, a full CGI window replacement, meaning the entire frame and sash removed and a new impact-rated unit set, typically runs $850 to $1,800 per window for standard sizes. Larger openings, second-story access, and stucco repair around the frame push the range toward $1,500 to $2,400. A sash-only replacement, where the frame is sound and the moving panel is the only problem, usually lands between $450 and $900 per sash.
Every quote we write includes the part, the labor, the disposal of the old unit, and the re-sealing of the opening. Both manufacturer warranty layers get registered in writing before we leave the driveway, and our workmanship carries the Done Right Promise. You will not see a change order appear because the opening was out of square, we measure twice before any price is final. That is what “a square deal” means to us, the number on the paper is the number on the bill.
DIY or Call Us?
There are things a Coral Gables homeowner can safely check before calling: read the product label and photograph it, note which window or door it is, and feel around the frame for soft spots or daylight. What an owner should not attempt is pulling a CGI sash out of its frame, especially on a second-floor unit or any window wider than about four feet. These sashes are heavy, and the balance systems and corner keys are under constant tension. A dropped CGI sash does not just break the glass; it can take out stucco, tile, or a hand on the way down.
If the window is fogged, losing its coating, or fighting you to operate, call (954) 507-3613. We will come measure, confirm the series from the label, and put the replacement options in writing before any work begins. Most CGI replacement calls in Coral Gables are resolved in one visit.
FAQs
CGI windows in Coral Gables generally last twenty to thirty years as complete assemblies, but seals commonly fail between ten and fifteen years due to the combination of salt air, humidity, and intense sun exposure. Hardware like crank gears and locks often needs replacement sooner, usually around the eight to twelve year mark. Call (954) 507-3613 if yours is fogged or fighting you, we will tell you honestly whether it is worth repairing or time to replace.
Yes, in many cases. If the frame and corner structure are sound, a failed insulated glass unit or worn sash hardware can be replaced without pulling the entire window. The exception is when the frame shows corrosion at the joints or the opening has shifted out of square, at which point a full replacement is the honest fix. Call (954) 507-3613 for a quote, estimates are free and you will get both options in writing.
A standard single-sash or single-window replacement in a Coral Gables home is usually completed in two to four hours once the unit is on site, and most jobs are done in a single visit. Full frame replacements with stucco repair can run half a day. Call (954) 507-3613 and we will give you a straight schedule before any deposit changes hands.
