CGI Window Replacement Nationwide | Sightline Windows & Doors Fort Lauderdale

CGI Window Replacement: The Fort Lauderdale Owner’s Guide

CGI window replacement in Fort Lauderdale typically runs $340 to $780 per opening for standard sizes, with most units in stock or available within 48 hours through our verified supply chain. We stock CGI-compatible hardware, sash packs, and full-frame replacements for Series 238, 312, and Estate Collection units - the three lines we see most often in Fort Lauderdale homes built between 2015 and 2022. Most owners discover the problem when a sash won’t stay open, when condensation appears between panes of a supposedly sealed unit, or when the crank mechanism on a casement strips out after repeated salt-air exposure.

Which CGI Models This Applies To

CGI manufactures three distinct product tiers, and the replacement approach differs for each. The Series 238 is their entry impact-rated vinyl line, common in Fort Lauderdale duplexes and townhomes east of Federal Highway; replacement sashes carry a 2-1/4 inch frame depth and use a proprietary cam-lock system that aftermarket hardware rarely fits correctly. The Series 312 upgrades to aluminum construction with thermal break - we see these in Victoria Park and Coral Ridge remodels where the original 238s are being swapped for better U-factor performance. The Estate Collection uses heavier extrusions and custom glazing beads that must be ordered by CGI part number; the bead profile changed in 2019, so a 2017 unit and a 2021 unit sitting side by side in a Rio Vista home may need different replacement components.

Identifying your unit requires two things: the etched mark in the glass corner (shows manufacturing date and Miami-Dade NOA number) and the frame depth measurement taken from interior drywall to exterior stucco. We carry OEM sash balances for 238 and 312 series on our trucks; Estate Collection hardware ships from CGI’s Hialeah distribution center, usually two business days. Sightline Windows & Doors Fort Lauderdale is an independent service provider, not affiliated with CGI. We also stock parts for PGT, CWS, and ES Windows units when a full replacement makes more sense than chasing a discontinued CGI component.

Before

After

Signs Your CGI Window Replacement Is Failing

• The sash drops or won’t stay open. This is almost always a failed coil balance in the 238 series or a broken block-and-tackle in the 312. Salt air corrodes the spring housing faster than inland specs predict; we replace these with stainless-steel equivalents rated for marine environments.
• Condensation between the panes. The insulated glass unit (IGU) seal has failed. In Fort Lauderdale’s humidity, this happens when the desiccant inside the spacer bar saturates, typically 8 to 14 years after manufacture depending on eastern vs. western exposure.
• Crank handle spins without moving the sash. The operator gearbox has stripped. CGI used two different operator manufacturers between 2015 and 2020; the mounting hole pattern differs by 3/8 inch, so the replacement must match the original casting number stamped on the housing.
• Visible frame distortion or corner separation. Thermal expansion in dark-colored aluminum frames accelerates this on west-facing walls. We measure the diagonal before quoting; anything over 1/4 inch out of square means the frame, not just the sash, needs replacement.
• Water intrusion at the sill after heavy rain. Usually the weep system is clogged with salt residue and insect debris, but sometimes the sill flashing was never integrated correctly with the Fort Lauderdale stucco wrap. We photograph the drainage path before disassembly so the fix addresses the actual path, not just the symptom.

Replacement Cost & What’s Included

What drives the range: frame size, whether the original installation used CGI’s specified rough-opening tolerance (we find 30 percent of Fort Lauderdale homes do not), and whether the exterior stucco needs repair after unit extraction. Our quote is the measured survey you keep; the final invoice matches it. Haven Clause 1: Have it in writing. Every replacement carries the 365-Day Done Right Promise, and we leave a documented photo record of the completed opening.

DIY or Call Us?

There is one thing a CGI owner can safely check: open the sash fully and look for the etched glass mark and any visible part numbers on the balance or operator housing. Photograph these. That information determines whether the correct replacement is on our truck or needs to be ordered.

What goes wrong with DIY: the 238 series sash pack weighs 35 to 50 pounds depending on size, and the balance must be tensioned with a specific winding tool - without it, the sash can drop unexpectedly and shatter the new IGU before it is seated. The 312 series uses tamper-resistant screws at the hinge jamb that strip easily with the wrong driver. And in any impact-rated unit, disturbing the glazing bead without the correct nylon setting block risks voiding the Miami-Dade NOA compliance that your insurance policy may require documented. We are background-checked, uniformed, and identified by license number before arrival; the person at your door is the person on the record. Call (754) 666-7478 to schedule your free estimate.

FAQs

How long does a CGI window last in Fort Lauderdale?

IGU seal failure typically appears at 8 to 14 years on eastern exposure, 10 to 16 years on the north side. Hardware fatigue varies with use frequency; coastal homes east of A1A see corrosion-related failures 3 to 5 years sooner than inland Fort Lauderdale properties. Call (754) 666-7478 for an exact quote on your specific unit - estimates are free.

Can the glass be repaired instead of replaced?

Once condensation appears between panes, the IGU seal is permanently compromised - there is no field repair that restores the argon fill or desiccant function. We replace the sealed unit, reusing the frame if it is square and structurally sound. Call (754) 666-7478 for an exact quote - estimates are free.

How long does the replacement take?

A standard sash pack swap in a square opening takes 90 to 120 minutes per unit. Full-frame replacement with stucco repair runs 4 to 6 hours. We schedule by the opening, not by the clock, and leave a documented photo record when finished. Call (754) 666-7478 to schedule your free estimate.

Do you stock CGI parts?

We carry Series 238 and 312 sash balances, operators, and glazing components on our trucks. Estate Collection and custom-size IGUs ship from CGI’s Hialeah facility, typically arriving within two business days. We verify availability against your etched glass mark before scheduling. Call (754) 666-7478 for an exact quote - estimates are free.

Sonia Raman keeps a running list of every product failure she’s seen and what caused it. She learned early, working summers with a glazing outfit in Burbank, that measure it right the first time or measure it twice on someone else’s dime. That principle is why every Sightline engagement begins with a measured survey the customer keeps, and why the written quote cannot differ from that document.
