CGI Energy-Efficient Windows in Fort Lauderdale: What to Know First
CGI energy-efficient windows in Fort Lauderdale are impact-rated hurricane windows built around insulated laminated glass, Low-E coatings, and argon gas fills that keep cooling costs down while standing up to Atlantic storms. As an independent CGI service provider, Winslow Windows & Doors repairs, replaces, and upgrades CGI windows across Fort Lauderdale, typically completing most energy-efficiency work within three to five business days after diagnosis. Our pricing is straightforward: window energy upgrades on CGI units in this market generally run $85 to $240 per window for glass and seal work, while full replacement runs higher depending on the series and opening size.
If you own CGI windows and your electric bill has crept up, or you’ve noticed condensation between panes, fading on furniture near south-facing glass, or drafty sills, this page tells you exactly what’s happening and what it costs to fix. Call (904) 913-5886 and you’ll get a live person, not a voicemail, any hour of the day.
Key Takeaways:
- CGI windows are built for hurricane impact, but their energy performance degrades when seals fail, Low-E coatings break down, or argon gas escapes
- Most CGI energy-efficiency repairs cost between $85 and $240 per window; full replacement typically ranges $900 to $2,400 per opening in Fort Lauderdale
- Winslow carries both OEM CGI glass packages and quality aftermarket Low-E insulated units, so you’re not locked into one price
- We’re locally owned since 2011, every tech is background-checked and uniformed, and the 36500-Day Done Right Promise covers every CGI job we do
How CGI Products Fail - and How We Fix Them
CGI builds a tough window. But Fort Lauderdale’s salt air, relentless UV, and summer humidity find the weak points in any window over enough years. Here’s what we see most on CGI units in this area and how we address each one.
- Failed argon gas seals on CGI Estate and Targa series insulated glass. The Estate line uses a dual-pane insulated unit with argon between the panes for thermal performance. After roughly 10 to 15 years in Fort Lauderdale’s humidity, the flexible sealant around the spacer bar breaks down, argon leaks out, and the window loses most of its insulating value. The telltale sign is fogging or a milky haze inside the glass you can’t wipe off. The fix is a new insulated glass unit, and we can match either the OEM CGI glass package or a quality aftermarket Low-E unit, depending on your budget and warranty situation.
- Low-E coating degradation on south-facing CGI windows. CGI uses a microscopically thin metallic Low-E coating on the interior glass surface to reflect heat. On Fort Lauderdale homes where windows face dead south with no shade, we see that coating break down after prolonged exposure to intense UV and salt air, leaving a blotchy or cloudy appearance and reducing heat rejection. We replace the glass unit with a fresh Low-E or solar-control package and adjust the installation so the coating sits on the correct surface for maximum heat rejection.
- Weatherstripping rot on CGI casement and awning operators. CGI’s casement and awning lines seal tight when the weatherstripping is intact. But Fort Lauderdale’s wet-dry-wet cycle causes the compression gaskets to flatten and crumble over five to seven years. Air leaks then bypass the glass entirely, which defeats the energy performance even if the glass itself is perfect. We replace weatherstripping with OEM CGI gaskets or matching aftermarket stock, then test the seal with a smoke pencil so you can see the difference.
- Frame settling and twisted sashes on CGI sliding glass doors. On older Fort Lauderdale slab homes, soil shift from our boom-and-bust rainy seasons can settle a door frame enough that the sliding panel no longer seats square. A twisted panel leaves a gap at the corner, and conditioned air pours out. We re-square the frame, replace worn rollers with the correct CGI-spec hardware, and reset the panel so the interlock seals flush again.
- Laminated glass delamination on CGI Sentinel series near the ocean. East of US-1, salt spray and constant humidity attack the edge seal on laminated impact glass. Over time, moisture wicks between the laminate layers and creates a white, cloudy edge that creeps inward. We see this on Sentinel-series windows within a few blocks of the beach far more often than inland. The repair is a new laminated insulated unit, and for oceanfront jobs we recommend a marine-grade edge seal to buy more years between replacements.
Our CGI Energy-Efficient Windows Process
Here’s what a CGI energy-efficiency job looks like when you call Winslow, from the first conversation to the final walkthrough.
- 1
You call, a person answers. No voicemail, no call center. You describe what you’re seeing, and we schedule a visit at a time that works for you. No trip charge for homes in our county.
- 2
We diagnose on site. A background-checked, uniformed tech arrives, inspects each window, checks for seal failure, coating breakdown, air leaks, and frame issues, and walks you through what we find in plain English.
- 3
You get a written, line-item quote. We tell you whether the OEM CGI glass package or a quality aftermarket unit makes more sense for your budget and warranty, and the price won’t change once work starts.
- 4
We do the work. Glass units are measured precisely, ordered or pulled from our local supply, and installed with the same fastening and sealing standards CGI specifies. Permits are pulled when the job requires them, and we don’t cut corners on anchorage or sealant.
- 5
We test and verify. Every window gets checked for proper seal, smooth operation, and glass clarity. We show you the difference before we call the job done.

What CGI Energy-Efficient Windows Costs in Fort Lauderdale
Most CGI energy-efficiency work falls into clear price bands depending on what’s actually wrong. Here’s what homeowners in Fort Lauderdale can expect.
- Weatherstripping and seal replacement: $40 to $95 per window for gaskets, sweeps, and compression seals, including labor
- Insulated glass unit replacement (Low-E or argon): $185 to $340 per unit for standard CGI sizes, more for large Estate or Sentinel panels
- Full CGI window replacement: $900 to $2,400 per opening depending on series, size, and whether you need impact-rated glass or standard Low-E insulated glass
- Whole-home energy retrofit (10+ windows): $9,000 to $22,000 for full glass packages, frame seals, and hardware resets on a typical Fort Lauderdale single-story
What moves the price: glass type, window size, whether the frame needs re-squaring, and whether you choose OEM CGI glass or an aftermarket equivalent. We give you the numbers for both so you decide with full information. Every estimate is free, written, and itemized. Call (904) 913-5886 and we’ll give you exact numbers for your windows, not a ballpark range.

FAQs
A fogged CGI window means the insulated glass seal has failed and the argon gas has escaped. The repair is a new insulated glass unit, which typically costs $185 to $340 per window in Fort Lauderdale for standard Estate or Targa sizes, installed. Call (904) 913-5886 for an exact quote, the estimate is free.
In almost every case, we can replace just the insulated glass unit and keep your existing CGI frame, which saves you hundreds per window compared to full replacement. The exceptions are when the frame has sustained structural damage or the sash hardware is so worn that a new frame makes more sense long-term. We’ll show you the numbers for both paths and let you decide.
CGI’s written warranty covers the frame and original glass for a set period, and replacing a failed glass unit after that period with a quality aftermarket Low-E or laminated unit does not retroactively void the frame coverage. If your CGI windows are still under the manufacturer glass warranty, we’ll tell you and help you pursue that route first. We’re an independent CGI service provider, so our recommendation is about what’s best for your home, not what moves the most product.
Diagnosis happens at the first visit, and once we have precise glass measurements, most CGI insulated glass replacements are completed within three to five business days in Fort Lauderdale. Weatherstripping and seal work on existing units is usually done same-day or next-day. When you call, we’ll give you a straight timeline based on what we find.
When a CGI job requires a permit under Fort Lauderdale building code, we pull it, schedule inspections, and see it through to final approval. We don’t skip the process and we don’t leave you holding the paperwork. That’s standard practice on every job we do.
If your CGI windows aren’t performing like they should, call (904) 913-5886 for a free estimate. Ed Winslow’s name is on the door, and it means something.
