CGI Custom & Geometric Windows in Miami: What to Know First
CGI custom and geometric windows in Miami are our specialty at Winslow Windows & Doors. We install, repair, and replace arched, radius, trapezoid, and oversized CGI impact windows, and most jobs in the Miami area run one to three days from first measurement to final cleanup. Expect a straight price before we start, not after, and a free estimate every time.
If you own a CGI window and it’s fogging, binding, leaking, or the hardware’s gone sloppy, this page is for you. We’re an independent CGI service provider, meaning we’re not a corporate arm of CGI, but we work on their windows and doors constantly. Call (844) 901-4551 and a real person picks up.
How CGI Products Fail — and How We Fix Them
CGI builds good windows. But years of Miami sun, salt air, and hurricane cycles expose weak points just like any other brand. Here’s what we actually see on custom and geometric CGI units in the field:
- Radius and arched units losing their seal. On CGI Estate Collection and Targa Series windows, the insulated glass unit in curved frames flexes differently than square panes. Over time, the seal at the curve fails, showing fog or water droplets between the panes. In Miami’s humidity, this happens faster than inland. We replace the IGU and re-seat it with fresh setting blocks so the curve doesn’t pinch the seal again.
- Sagging on oversized fixed units. CGI’s Estate Collection includes some wide custom spans. In Miami homes with western exposure, we see the frame relax slightly over years of afternoon heat. The unit still locks, but there’s a hairline gap at the meeting rail. We purge and refill the frame with a fresh setting block layout, then adjust the hardware so the interlock closes tight again.
- Hardware fatigue on crank-out geometric windows. CGI casement and awning units used in custom shapes (like triangles or half-rounds) put a lot of torque on the operator arm. We see stripped gearboxes and bent arms on units that get cycled daily. We stock and install both OEM CGI hardware and, where the warranty’s already expired, high-grade aftermarket operators that outlast the originals.
- Water intrusion at custom mullion joints. When two CGI windows are mulled together to make a wide geometric opening, the splice point is the usual suspect for water entry in Miami’s summer storms. We remove the mullion cap, inspect the internal flashing, and re-seal with the right structural sealant, not whatever’s on the shelf at a big box store.
- Scratched or clouded glass on shaped panes. A curved or angled CGI window is a custom-order glass piece. The “I’ll just live with it” instinct is common, but it’s a mistake. We can often source replacement glass for CGI shapes faster than homeowners expect, and we’ll swap it without changing the frame.
Our CGI Custom & Geometric Windows Process
- 1
The phone call. You reach a live person at (844) 901-4551, day or night. We ask what’s happening with the window and schedule a time that works.
- 2
The diagnostic visit. We measure the rough opening, check the frame square, see how the unit sits in the wall, and identify why it failed. No charge for the trip inside our home county.
- 3
The straight answer. We tell you if it’s a parts fix, a glass replacement, or a full-unit replacement. If the warranty applies, we’ll help you understand what’s covered, but we never pretend a manufacturer will pay for something they won’t. We source OEM CGI parts when warranty matters; when it doesn’t, we’ll give you the choice of OEM or a quality aftermarket part and show the price difference.
- 4
The repair. Our techs do the work in uniform and on time. For curved glass and odd shapes, we’re careful with shims, glazing, and sealant application so the window sits right and won’t re-fail in six months.
- 5
The test. We run the unit through its full range, check for air and water leaks around the frame, and confirm the hardware operates smoothly. You watch the window work before we leave.
- 6
The promise. Every CGI job we do is covered by our Done Right Promise. If it’s not done right, we come back and make it right. That commitment has our name on it for a century, which is more than anyone can say about a ticket number from a national chain.
What CGI Custom & Geometric Windows Costs in Miami
Here’s the honest range for the work we do in Miami:
| Job Type | Typical Cost |
|---|---|
| IGU replacement on a curved CGI unit (parts and labor) | $600 – $1,300 per pane |
| Hardware replacement on a custom CGI casement or awning | $180 – $380 per operator |
| Frame re-seal and mullion reseal | $250 – $600 per mullion joint |
| Full CGI custom geometric window replacement | $1,800 – $4,500 per unit, depending on size, shape, and glass package |
What moves the price? The glass package matters most, then the frame color and finish, then whether the opening needs new buck framing or an updated anchor system to meet current Miami-Dade code. We’ll show you the line items and explain what drives the number. Call (844) 901-4551 for an exact quote. Estimates are free, and if you’re a senior or veteran, ask about the standing 10% discount.
Why Miami Homeowners Call Winslow Windows & Doors for CGI Work
The person who answers is a neighbor, not a call center. Ed Winslow founded this company in 2011 and has been working on South Florida windows since, including his time in the construction technology program at Miami Dade College’s Wolfson Campus. He grew up in Hialeah watching crews work the older concrete-block homes west of the Palmetto, and he’s been fixing what the weather does to them ever since.
We carry parts and glass for CGI Estate, Targa, and other lines. We also service PGT, CWS, ES Windows, and ECO Window Systems, so when a Miami home has a mix of impact brands, we can handle the whole call in one visit. Our techs are background-checked and in uniform before they hit your door. And if anything isn’t right, the Done Right Promise means we fix it, no fine print. The one down the road doesn’t have to mean the one you settle for.
FAQs
If we use OEM parts and don’t alter the frame, no. We’re careful to stay within what CGI’s warranty terms allow, and we’ll tell you plainly when a repair crosses into territory that could affect coverage. That’s the kind of straight answer you’ll get at (844) 901-4551.
Yes, we source replacement insulated glass for CGI arched, radius, trapezoid, and oversized units regularly. The glass order takes a few days to a couple of weeks depending on the shape and glazing. Call (844) 901-4551 with your window’s rough dimensions and we’ll get a lead time.
If the frame is sound and the failure is in the glass or hardware, repair is usually the right call. If the frame is bowed, water-damaged, or the unit predates current Miami-Dade impact codes, replacement may make more sense. We’ll show you the numbers both ways and let you decide.
We schedule quickly, and because a live person answers the phone 24/7, you’ll know your time slot before we hang up. No callback loops, no “we’ll text you a window.” Call (844) 901-4551 and let’s get it on the calendar.
Yes. While this page focuses on CGI, we’re authorized installers for PGT, CWS, ES Windows, ECO Window Systems, and others. If your Miami home has a mix, we’ll sort it out in one trip.
