CGI Window Replacement in Little Gables: What to Know First

CGI window replacement in Little Gables typically runs $850 to $2,400 per window installed, depending on the series, glass package, and whether you’re doing a full frame or insert replacement. We’re an independent CGI service provider, not a manufacturer affiliate, and we usually complete most single-window replacements in one day once your new unit arrives. Ed Winslow has been replacing CGI windows in South Florida for over 15 years, and this page tells you what actually matters before you spend a dime.

Call (727) 291-4678

If you own a CGI window that’s fogged, binding, leaking, or just tired, call (727) 291-4678. You’ll reach a live person, not a call center.

How CGI Products Fail - and How We Fix Them

CGI builds a tough window. But Little Gables humidity, salt air, and afternoon thunderstorms find the weak spots in any window over time. Here’s what we see most on CGI jobs in Little Gables and how we address it:

• Sentinel series seal failure and fogging. The Sentinel line is common in older Little Gables homes, and its insulated glass units can lose their seal after 12 to 18 years of South Florida humidity cycles. Once argon escapes and moisture gets between the panes, you see permanent haze. We don’t patch this; we replace the glass unit or swap in a new window if the frame’s gone too. Patching a failed seal never lasts.
• Estate Collection roller and balance wear. Horizontal sliders and single-hungs in the Estate line carry a lot of sash weight, and the nylon rollers and block-and-tackle balances flatten out. Symptoms: sash that scrapes, tilts, or won’t stay up. We replace worn rollers and balances, and if the track is grooved from years of dragging, we tell you straight: a new window beats a parts fix.
• Frame corrosion at the hardware on Clad/Coastal series. CGI’s coastal-rated frames are built for salt exposure, but on Little Gables homes within a mile of the bay, aluminum hardware in contact with salt-laden air can corrode at the fasteners. That’s a water intrusion point. We inspect the full perimeter during replacement, not just the glass, and use marine-grade fasteners when we rebuild.
• Opening binding after settling or slab movement. Little Gables sits on limestone-influenced soil, and older pier-and-beam or slab foundations shift over decades. A CGI window that opened smoothly ten years ago might now bind because the opening has drifted. Our techs measure the reveal on all four sides before we order a replacement, because a square window in an out-of-square opening is a recurring leak.
• Latch and multipoint lock failure on Targa and Sentry series. The locking hardware on impact-rated CGI units takes a beating, especially on doors and casement windows that get opened daily. A broken multipoint lock is more than a nuisance; it compromises the impact rating because the sash isn’t fully seated against the weatherstripping. We source OEM CGI hardware or exact-match aftermarket replacements that preserve the pressure rating.

Our CGI Window Replacement Process

Here’s exactly what a CGI window replacement in Little Gables looks like when we do it, from first call to final walkthrough:

1. 1
   Call and scheduling. You call (727) 291-4678. A live person answers, asks about the problem, and we set a visit time. No voicemail tag, no call-back roulette.
2. 2
   On-site diagnosis. Our technician measures the window, inspects the frame and rough opening, checks for water intrusion, and identifies the exact CGI series and any failure. We give you a written line-item quote before we order anything.
3. 3
   Parts decision. We discuss OEM CGI glass and parts versus quality aftermarket options that match performance and preserve warranty coverage. We never hide this decision in the quote; you choose with full information.
4. 4
   Replacement installation. On install day, we protect the interior, remove the old unit, address any frame or flashing issues, set the new window, and seal it to CGI’s installation tolerances. For impact-rated units, this means full perimeter anchoring, not dabs of caulk.
5. 5
   Testing and cleanup. We operate every sash and lock, test for air and water infiltration around the perimeter, and clean the glass and work area. If it doesn’t pass our inspection, it’s not done.
6. 6
   Final walkthrough and warranty. We walk the job with you, explain what we did, and confirm the work is covered by the Winslow Done Right Promise. Ed’s name is on it.
