This page is for people who bought CGI windows because they were told they’d save energy, and now the electric bill says something different. We’ll show you what actually goes wrong with these windows in South Florida, what it costs to fix, and how to know if you’re better off replacing.

How CGI Products Fail - and How We Fix Them

• Fogged glass on CGI Estate Collection picture windows. The Estate Collection uses a dual-pane insulated glass unit with a desiccant-filled spacer. In Little Gables, the humidity sits above 80% for half the year, and once the perimeter seal on that spacer gives out, moisture gets pulled into the air gap and it’s over. You can’t wipe it off from either side. We replace the full IGU with a Low-E argon-filled unit and re-glaze the sash, which brings the window back to its original ENERGY STAR rating instead of just clearing the view.
• Drafty sashes on older CGI Sentinel Series single-hung windows. Sentinel Series windows from the mid-2000s used a weatherstripping profile that flattens out over time in Florida’s heat. The window doesn’t sag like a cheaper vinyl frame does, but air starts slipping past the meeting rail. We pull the sash, check the balance system for wear, replace the weatherstripping with a high-density foam profile, and reset the tilt latches. Fixing the air gap on a Sentinel is usually a fraction of what a full replacement costs.
• Low-E coating degradation on south-facing CGI fixed windows. This is one we see all over Little Gables on windows facing Coral Way or any street with no shade. The Low-E coating on the interior face of the outer pane starts to break down after years of direct UV exposure. It looks like a cloudy film that won’t clean off. Homeowners think the glass is dirty, but it’s the coating failing. Replacement glass with a fresh Low-E layer restores the heat rejection, and we can spec a stronger UV-blocking film if the window gets hammered by afternoon sun.
• Condensation between panes on CGI Targa Series casement windows. Targa casements have a narrow frame profile, which looks great but leaves less room for the insulated glass seal. After 10 to 12 years in a coastal humidity zone like Little Gables, the seal around the IGU edge can fail and you’ll see beads of water form between the glass. We measure the existing unit, order the correct thickness with a matching spacer pattern, and swap it in. The frame and crank hardware stay intact, so you keep the original look without paying for a whole new window.
• Argon gas loss that makes the window feel warm to the touch. CGI windows built for hurricane zones are laminated and heavy, which is why they hold up in a storm. But any dual-pane window loses a small percentage of argon gas per year, and eventually the window starts transferring heat through the gap. You can feel it standing next to the glass in August. It’s not a leak you’d notice as a draft, just a window that stopped doing its job. When we replace the IGU, we confirm the fill rate and use a warm-edge spacer to slow future gas loss.

Our CGI Energy-Efficient Windows Process

1. 1
   Call and talk to a real person. You call (727) 291-4678, someone at our office picks up, and we ask what the window is doing. We’ll usually know within a few minutes whether we’re looking at a seal failure, a hardware issue, or a full replacement.
2. 2
   On-site inspection and measurement. We come out to your Little Gables home, inspect the window and the ones next to it, and take exact measurements. We check the frame, the glazing, the balance system, and the condition of the existing Low-E coating.
3. 3
   Straightforward options. We tell you what’s wrong, what it costs to fix, and whether a repair or a replacement makes more sense for your situation. If the frame is solid, we don’t sell you a new window. If it’s not, we say so plainly.
4. 4
   Parts decision. For CGI windows we use OEM glass and hardware whenever it’s available and the right call. For older or discontinued lines, we source quality aftermarket IGUs that meet or exceed the original spec. Warranty-safe practice is always the priority.
5. 5
   The work, done right. We replace the glass unit, re-seal the sash, reset the hardware, and test the window for air leaks and smooth operation before we clean up.
6. 6
   Done Right Promise. If something isn’t right, we come back and make it right. That’s the whole promise. No fine print about when it expires.

What CGI Energy-Efficient Windows Costs in Little Gables

Here’s what we’re seeing in the Little Gables market right now:

• Glass-only replacement (seal failure or coating breakdown): $185 to $420 per window, depending on size and whether it’s laminated or tempered.
• Full IGU replacement with Low-E argon glass on a CGI Estate or Sentinel: $260 to $480 per window.
• Weatherstripping and balance repair on a single CGI window: $90 to $180.
• Energy audit on all windows plus a written report: $150 to $275, applied toward any repair you approve.

What moves the price is the glass spec, the window size, and whether we’re dealing with a second-story installation or a window that needs scaffolding. Little Gables homes run from 1920s bungalows to newer builds, so the frame condition matters too. Call (727) 291-4678 for an exact quote. Estimates are free, and our pricing is upfront, no surprises on the invoice.

Ed Winslow’s name is on the door, and on every job we do. We’ve been doing this in South Florida since 2011, and we’re still here because we answer the phone and stand behind the work. When a Little Gables homeowner calls us about a CGI window that’s fogged up or leaking air, they get a tech who knows CGI’s product lines, not someone reading a script off a tablet.
