CGI Custom & Geometric Windows in Coral Gables: What to Know First

We’re an independent CGI service provider in Coral Gables, and we handle custom impact windows, arched and curved designs, and oversized geometric openings that most window companies won’t touch. Most CGI custom & geometric window repairs or replacements in Coral Gables are quoted within 48 hours, and many jobs are completed in two to three weeks once materials land. The honest pricing posture is this: custom shapes cost more than standard rectangles, but you’ll get a written line-item quote before any work starts, and the price on that quote is the price you pay.

This page is for Coral Gables homeowners who already own CGI windows, or who are planning a remodel with custom shapes and want a straight answer about what works. If you need a real person to talk it through, call (904) 478-8983.

How CGI Products Fail - and How We Fix Them

We’ve been working on CGI windows in Coral Gables long enough to know exactly where they show their age. Here’s what we see most often with custom and geometric shapes specifically:

• Custom arched transoms losing their seat. CGI’s Estate Collection and Custom Series arched windows are gorgeous, but the curved frame puts uneven pressure on the sealant bed where the glass meets the frame. In Coral Gables, the combination of intense afternoon sun on western exposures and salt air from the coast breaks that seal down faster than it would on a vertical rectangle. We remove the old glazing, clean the channel, and re-bed the glass with commercial-grade marine sealant. Done right, it holds another decade or more.
• Geometric picture windows with failing laminated interlayer. CGI’s impact glass uses a polyvinyl butyral interlayer that can develop a milky haze at the edges over time, especially on large trapezoid and pentagon shapes where the glass flexes more during storms. It doesn’t shatter, but it looks wrong, and it can let moisture creep between the panes. We replace the insulated glass unit, matching the original shape exactly, and we spec the replacement from a glass fabricator that cuts true geometric angles, not rounded approximations.
• OEM hinge and roller wear on operable custom shapes. Some CGI custom windows use multi-point locking hardware on arched casements, and the bottom hinge takes the brunt of the weight on taller openings. We’ve seen the pivot bearing wear to the point where the sash drops a quarter inch and rubs the frame. CGI sells replacement hardware, but the wait can stretch weeks. We keep high-grade aftermarket equivalents in stock for the most common CGI hinge profiles, and we’ll tell you honestly when OEM is worth the wait and when it isn’t.
• Weep hole blockage in radius-bottom and oval windows. Any curved custom shape has tighter weep channels than a standard sill. Corrosive dust and heavy Coral Gables rains can clog them, and then water pools inside the frame. You’ll see condensation that never goes away. We clear and enlarge the weep paths, treat them to resist corrosion, and test with water before we leave.
• Flange seal failure on oversized openings. When a Coral Gables home has floor-to-ceiling geometric window walls, the aluminum flange that ties into the structure takes enormous thermal expansion stress. CGI specifies a particular expansion allowance, but if the original installer skipped the expansion joint, the flange will tear its own sealant over a few hurricane seasons. We demo the old flange, install an expansion-compliant sealant system, and re-tape the opening to match CGI’s own water management detail.

Our CGI Custom & Geometric Windows Process

Here’s how a typical CGI custom window job goes with us, from first call to final walkthrough:

1. 1
   Call and schedule a visit. You call (904) 478-8983, tell us what you’re seeing. We schedule a time that works for you, and there’s no trip charge inside the home county.
2. 2
   We measure and document everything. For custom shapes, we take exact field measurements, photograph the existing window, and note the trim details. We don’t trust rough dimensions on anything that isn’t a rectangle.
3. 3
   Parts decision: OEM or aftermarket. We tell you the wait time and cost for genuine CGI parts versus a quality aftermarket option, and we let the warranty situation drive the recommendation. If your CGI warranty is still active, we push OEM. If it’s long expired, we show you both numbers.
4. 4
   Written quote with line items. You get a fixed-price written estimate. No change orders, no “we found something else” surprises. If we find something else, that’s on us for not catching it during diagnostics.
5. 5
   The work and the test. Our background-checked, uniformed technicians do the removal, the framing, the install, and the seal, then test the window for operation, air infiltration, and water drainage. We don’t leave until it passes.
6. 6
   The Done Right Promise. If a year from now, a hinge sticks or a seal fails on work we did, Ed Winslow’s name is on the work order and we come back to make it right.

What CGI Custom & Geometric Windows Costs in Coral Gables

Custom and geometric CGI windows in Coral Gables run on a different cost curve than standard windows, and here’s the range we see most often. A straightforward arched transom glass replacement runs roughly $900 to $1,800 depending on size and glass package. Replacing an entire custom-shaped window in an older Coral Gables home, frame and all, typically falls between $2,500 and $6,000 per opening, and can go higher for oversized or complex geometry. Hardware and seal repairs on existing windows usually land between $300 and $900 per window. What moves the price most is the glass package, the frame finish, and whether the existing rough opening is square enough to work with or needs corrective framing.

FAQs

Will repairing or replacing my CGI custom window void the manufacturer warranty?
In many cases, using an independent installer does not void the warranty so long as the work meets CGI’s installation specifications, which we follow. If your warranty is still active, we recommend OEM parts and we’ll document the work so you have everything you need for a claim. Call (904) 478-8983 and we’ll walk through your specific warranty terms.

Can you match a geometric window that another contractor installed wrong?
Yes. We field-measure every custom shape ourselves, with our own equipment, and we don’t trust the old opening’s dimensions if the original install was questionable. We’ve corrected out-of-square openings in Coral Gables homes more times than we can count.

What’s the turnaround time for a custom CGI window replacement?
Most custom shapes take two to three weeks from the day we place the order to the day we install, depending on the glass package and whether we’re sourcing OEM or aftermarket. You’ll get a target date in your quote, not a vague “we’ll call you.”

Should I repair or replace my old CGI geometric window?
If the frame is straight, the glazing channel is intact, and the glass unit is the only problem, a glass replacement makes sense and saves real money. If the frame is corroded, the flange is compromised, or the window is over 20 years old, replacement is the better long-term move. We’ll give you both numbers and let you decide without any pressure.

Is there a cost savings if I bundle several custom windows into one project?
Yes, in most cases, the per-window cost drops when we’re mobilizing once and fabricating multiple shapes at the same time. Tell us your full scope up front, and we’ll line-item the whole thing so you can see the savings.
