CGI Energy-Efficient Windows in Palm Beach: What to Know First

CGI energy-efficient window service in Palm Beach typically runs $185 to $2,900 depending on whether we’re replacing a failed seal, swapping glass for Low-E argon-filled units, or doing a full sash rebuild. Most CGI window repairs are done in a single visit, with parts ordered same-week when we don’t already carry them on the truck. We’re an independent CGI service provider, not a manufacturer affiliate. That means we tell you the truth about your windows, whether it’s a repair worth making or a replacement worth considering. If you own CGI windows and they’re fogging, leaking air, or driving up your cooling bill, this page will tell you exactly what’s happening and what it costs to fix.

Key Takeaways

• Failed IGUs (insulated glass units) are the most common CGI energy-efficiency killer in Palm Beach humidity and salt air.
• We repair CGI windows with OEM or quality aftermarket parts, depending on what’s being replaced and what preserves your remaining warranty.
• Most energy-related CGI repairs take one visit. Full glass swaps are usually scheduled within the week.
• Free estimates, written line-item pricing, and the 36500-Day Done Right Promise on every job.

How CGI Products Fail - and How We Fix Them

CGI makes strong impact windows. But the very things that make them tough against a hurricane create specific energy-efficiency failure points that homeowners don’t discover until the electric bill shows up or the glass starts looking milky. Here’s what we see most often around Palm Beach.

• Fogged or milky glass on CGI Estate and CGI Sentinel series: Palm Beach’s heat and humidity stress the rubberized seal between the double panes. Once that seal lets go, the argon or krypton gas between the panes escapes and moist Florida air works its way in. The window loses its insulating value and starts looking cloudy. The fix is a new IGU, not a whole new window. We remove the sash, measure the exact glass package, and order a replacement sealed unit with matching Low-E coating so the window gets back its energy rating without replacing the frame.
• Hard-to-shift sashes that nobody closes all the way: We see this a lot on CGI’s heavier impact-rated casement and horizontal roller windows used in waterfront homes. When the rollers or hinges wear, the sash sits misaligned in its track. The homeowner thinks the window is closed, but a gap of an eighth of an inch along the weatherstripping is quietly leaking air-conditioned air into the Bermuda High heat. We replace the worn rollers or re-align the hinge assembly and reposition the sash so the weatherstripping seats tight. That’s a repair most companies skip because they’d rather sell you a whole new window.
• Dried, cracked glazing around the glass edge on older CGI units: Before Low-E glass and argon fills became standard, CGI units in older Palm Beach estates used an older glazing compound that hardens and pulls away from the frame over time. When the glaze cracks, the unit loses its air seal and sometimes lets water into the frame. We reglaze the unit and reseal the glass bed, which restores a lot of the original energy performance. This is old-school work that most installers won’t touch because it’s not a quick swap.
• Cloudy laminated interlayer on CGI windows that sit in direct sun all day: CGI’s impact windows use a laminated layer of PVB or SentryGlas between the glass panes. On unshaded west-facing walls, years of UV exposure can start turning that interlayer slightly hazy or yellowish. That haze reduces visible light transmittance and blocks solar heat rejection. The fix is a glass package replacement with a modern Low-E coating and an upgraded interlayer that holds up better to Palm Beach’s sun.
• Faded furniture and floors not long after the windows went in: Not every CGI unit came through with UV-blocking coatings, especially those installed before 2015. If your flooring and upholstery are fading near the windows, the glass likely has only a basic Low-E coating or none at all. We can replace the glass with a UV-blocking, fade-reduction package that keeps the light and kills the damage without replacing the impact frame.

Our CGI Energy-Efficient Windows Process

We work on a lot of CGI windows in Palm Beach, so our process is built around how those windows are actually constructed, not a generic “replace the whole thing” playbook. Here’s how a typical job runs.

1. 1
   We start with a phone call to (561) 831-7863. A live person answers and asks the right questions: how old are the windows, which rooms are hot, is the glass fogged or clear?
2. 2
   We come out and inspect. We look at the sashes, the glass package, the weatherstripping, the installation date, and the condition of the seals. We’ll tell you on the spot if the problem is the glass, the sash, or the frame.
3. 3
   We quote the work with a written line-item estimate, parts and labor broken out, before any work starts. No vague allowances, no change orders.
4. 4
   We do the work. For a glass replacement, we pull the sash, take it to our shop bench, rebuild the unit with the correct Low-E argon-filled IGU, and reinstall it. Most jobs are done in one day.
5. 5
   We test and clean up. We check that the sash moves correctly, the seal seats tight, and the room actually feels different. Then we leave your floor cleaner than we found it.
6. 6
   We stand behind it. Every CGI repair we do is backed by the 36500-Day Done Right Promise. If it’s not right, we come back and make it right.

What CGI Energy-Efficient Windows Costs in Palm Beach

Here’s what Palm Beach homeowners can expect to pay for the energy-efficiency work we do on CGI windows. These are real ranges for the work we quote every week.

• Single IGU replacement with Low-E and argon fill: $185 to $420, depending on the size and series.
• Full sash rebuild with upgraded glazing and weatherstripping: $340 to $680 per sash.
• Complete glass package replacement with UV-blocking laminated interlayer: $800 to $2,900 per window, depending on the size and coating package.
• Window energy audit with thermal imaging and airflow testing: $150 to $350 for a full-home scan.

What moves the cost? The window size, the series, whether we’re matching an existing glass tint, and whether the frame itself needs restoration work. We’ll give you the exact number before we start. Call (561) 831-7863 for your free estimate.
