CGI Energy-Efficient Windows in Fort Lauderdale: What to Know First
We install, replace, and service CGI energy-efficient windows throughout Fort Lauderdale as an independent CGI service provider. Typical turnaround for a full replacement runs two to four weeks from signed quote to cleanup, depending on glass lead times and permitting. Pricing runs honest and line-itemed: most energy-efficient CGI replacements in Fort Lauderdale land between $1,400 and $3,800 per opening, installed, and you will see that number on paper before we touch a wall.
This page is for homeowners who own CGI windows and doors, or are considering them, and want a straight answer on what holds up, what fails, and what it costs to make it right. If you have a fogged pane, a failed Low-E coating, or a utility bill that climbs every July, call (954) 280-4413 and a live person answers – day or night.
How CGI Products Fail - and How We Fix Them
CGI builds a serious impact product. The aluminum frames are heavy, the glass is thick, and the engineering is coastal-tested. But energy efficiency on a Fort Lauderdale window is a different conversation than impact rating. Here is what we actually see on CGI units after years of salt air and sun:
- Seal failure on CGI Estate and Targa series insulated glass units. The sealant between the panes breaks down, moisture creeps in, and you get the fog you cannot wipe away. What most homeowners do not know is that the window still passes impact testing even with a failed seal. It just does not insulate anymore. We measure the exact glass thickness and replace the IGU with a matching Low-E unit rather than swapping the whole sash.
- Low-E coating degradation, most common on south-facing CGI Sentry and Estate windows. Fort Lauderdale’s UV load is brutal. Over a decade or so, the microscopic metallic coating inside the glass can oxidize, which shows up as a hazy or slightly bronzed look from inside. The window looks dirty but will not clean up. That is not surface grime; that is the coating itself going. We replace the glass pack, and we will show you the difference under a thermal imager before and after.
- Weep-hole blockage on CGI casement and horizontal slider frames. CGI frames drain through small weep channels at the sill. In Fort Lauderdale, wind-driven rain plus pollen plus salt crust those holes shut, and water backs up into the track. You will see water stains at the interior corners and eventually rot in the rough opening if it is wood. We clear the weeps, verify drainage with a controlled water test, and replace any sill gaskets that have gone flat.
- Thermal bridging on older CGI aluminum frames without a thermal break. Aluminum conducts heat beautifully, which is a problem. Homes with early CGI installs, think mid-2000s, often have frames that get hot to the touch in August. That heat transfers straight into the house. The fix depends on the frame condition. Sometimes we can retrofit with thermally broken sashes. Sometimes the honest answer is replacement, and we will quote it side by side so you can see the arithmetic.
- Gas fill loss in double-pane CGI units. Argon or krypton between the panes boosts the insulating value. When the seal goes, the gas escapes – you will not see fog right away, but the window’s U-factor quietly falls. An energy audit with our thermal camera shows exactly which panes have lost their fill. Most homeowners are surprised to learn the glass looks fine but is doing half its original insulating job.
Our CGI Energy-Efficient Windows Process
- 1
You call, a person answers. We ask about the symptoms, not the part number. Fog, drafts, heat gain, binding. Then we schedule a site visit at a time that works for you.
- 2
We measure every opening twice. This is Dale’s rule, and it never changes. We also check the rough opening for rot, settling, and water intrusion before quoting.
- 3
We put options on paper, side by side. OEM CGI glass versus quality aftermarket for the same spec, or replacement window lines if the frame is beyond saving. You see the numbers, the warranty terms, and the energy ratings before you decide.
- 4
We do the work in one visit when we can. For glass replacement, most CGI jobs are done in a single day. For full-frame replacement, we stage the work and keep the site clean and tarped.
- 5
We test before we leave. Water test on the sills, thermal scan on the glass, and we operate every sash three times. If it binds, we adjust it. If the pane is not true, the job is not done.
- 6
Both warranty layers go into your hand. The glass manufacturer’s warranty and our Done Right Promise, registered in writing, durations stated, before the truck pulls away.
What CGI Energy-Efficient Windows Costs in Fort Lauderdale
| Scenario | Typical Range (Installed) |
|---|---|
| IGU replacement, single pane, Low-E insulated glass | $450 - $900 |
| IGU replacement on a CGI Estate or Targa sash, field-glazed | $700 - $1,400 |
| Full replacement window, CGI or equivalent energy-efficient unit, per opening | $1,400 - $3,800 |
| Sill gasket / weather-seal rebuild on one CGI jamb | $180 - $420 |
| Whole-home energy audit with thermal imaging (no repairs) | $220 - $400 |
What moves the price: whether the sash comes out whole, how the old glass was set, whether we are matching tint or Low-E spec on existing windows, and how much frame work the rough opening needs. You will get the number in writing before we start, and the number on the bill will match the number on the quote. Call (954) 280-4413 for a free estimate.
Why Fort Lauderdale Homeowners Call TruePane Windows & Doors for CGI Work
We have been at this in Fort Lauderdale since 2008, and Dale Kessler has been doing glass work in the coastal corridor since before most of the current tract developments went up. That matters on a CGI job because the failure modes are product-specific, and we have seen enough of them to know what a fogged seal means, what a bronzed Low-E coating means, and which part is worth replacing versus which sash needs to go.
Every job leaves with both warranty layers registered in writing under The Keystone Standard, and our Done Right Promise means if something is not right, we make it right – no paperwork fights, no arguing. We also work on Andersen, Pella, and PGT, so if a mixed-brand house needs attention, one crew handles it all. Background-checked, uniformed technicians on every job, and a live person answers the phone 24 hours a day.
FAQs
No, not when it is done correctly. CGI’s warranty covers the frame and the original glass against manufacturing defects. Replacing a failed IGU with properly specified glass does not void the frame warranty. We verify the original warranty status before we touch the sash, and we register both warranty layers in writing under The Keystone Standard. The key is that the new glass must meet the same spec rating as the original, and we make sure it does. Call (954) 280-4413 and we will check your specific units.
If the frame is square, the drainage channels are clear, and the operator hardware works, glass replacement is almost always the better dollar. Fogged seals, failed Low-E coating, and lost gas fill are glass problems, not frame problems, and the fix is $450 to $1,400 instead of $1,400 to $3,800. We will tell you straight if the frame is not worth saving, and show you the numbers on paper either way.
A single-pane or sash-glazed IGU replacement is typically a one-day job. Full-frame replacement runs two to four weeks start to finish, mostly driven by glass lead times and the city permitting schedule. We will give you a firm date at quote, and we will be there when we say.
Yes. We match tint, Low-E spec, and glass thickness against the existing units so a replaced pane does not stand out from its neighbors. CGI has used several glass packages over the years, and we keep samples and documentation on the common ones. If your exact spec is no longer available, we will show you the closest match side by side before we order.
No. The quote you sign is the price you pay. If we find rot or water damage in the rough opening that could not be seen before demolition, we stop and put the additional scope in writing before we proceed. No surprise line items on the bill, ever. That is a square deal, and we stand behind it.
If your CGI windows are fogged, hot to the touch, or the utility bill is climbing, call (954) 280-4413 for a free estimate. A live person answers, and we will give you straight answers on what is worth fixing and what is worth replacing.
