CGI Custom & Geometric Windows in South Miami: What to Know First
Custom and geometric CGI windows in South Miami need a specialist who understands how shaped glass performs under hurricane load, not just how to order a stock rectangle. We provide independent CGI custom and geometric window service across South Miami, including diagnosis, parts sourcing, glass replacement, and full frame work. Most CGI custom window repairs run $340 to $1,200 depending on the shape, glass package, and what failed. If you own CGI arched, radius, trapezoid, or oversized windows and something isn’t right, call (850) 930-1813 and you’ll get a real person.
This page is for South Miami homeowners who already have CGI windows (or are considering them) and need custom or geometric work done correctly. We’re an independent CGI service provider, which means we can tell you the truth about what’s worth fixing and what isn’t, without a manufacturer’s sales script behind us.
Key Takeaways
- We work on CGI custom and geometric windows daily across South Miami, from Coral Gables border homes to the neighborhoods around Dante Fascell Park.
- Most CGI shaped-window failures are seal or hardware issues, not full frame replacements. We tell you which one you have before you spend a dime.
- Every estimate is free, written, and line-itemed. The price we quote is the price you pay.
- We’re not CGI authorized, but we know their product lines as well as anyone installing them since 2011.
How CGI Products Fail - and How We Fix Them
CGI builds strong windows. But custom and geometric shapes put stress on areas that stock rectangular windows never see. Here’s what we actually find when we open up CGI shaped windows in South Miami homes:
- Seal failure at the radius points on Arched and Eyebrow series windows. The curved glass on CGI’s radius windows puts uneven pressure on the spacer system, and after 8-12 years in South Miami humidity, the seals start letting go at the apex. You’ll see haze or moisture between the panes that comes and goes. We replace the insulated glass unit with a new one cut to the exact radius, not a “close enough” stock piece.
- Hinge fatigue on CGI casement geometric units. Non-rectangular casements, like pentagons and octagons used over fixed picture windows, weigh more per square foot at the hinge points. The hardware CGI ships works fine, but the South Miami salt air accelerates corrosion on the friction stays. We see windows that won’t stay open after year 6 or 7. The fix is new stainless hardware, not a whole new window, and we make that call honestly.
- Frame racking on oversized trapezoid openings. South Miami homes with large fixed trapezoid windows (the kind above a front door or over a transom) sometimes get micro-movement in the rough opening. Over time that transfers to the frame, and you’ll notice the window “sticks” or the reveal is uneven. We reset and shim the frame, re-flash it, and get the reveal back to true. This is one of the most common CGI custom window calls we run in South Miami.
- Laminate delamination on coastal-facing shaped units. CGI uses laminated glass in most impact-rated lines, and on geometric shapes facing east toward Biscayne Bay, we’ve seen edge delamination start at the sharp corners. It looks like a cloudy line creeping in from the edge. Once it starts, it doesn’t stop. We replace the glass with the correct CGI-spec laminate, not a generic impact panel that might not match the frame’s structural rating.
- Weep system clogs on radius-bottom windows. Half-round and oval windows with curved bottom edges have weep holes that South Miami’s rainy season can plug with dirt and pollen. Water pools, sits against the frame, and you get staining on the interior sill. We clear the weeps, re-pitch the sill track where needed, and seal the exterior properly. This one’s usually a $40 repair that prevents a $900 frame job, and our $40-off-any-repair-over-$200 standing offer applies.
Our CGI Custom & Geometric Windows Process
Here’s how a CGI shaped-window job runs when you call Winslow Windows & Doors:
- 1
You call (850) 930-1813. A live person answers, day or night. You describe what the window is doing. We schedule a visit. No trip charge if you’re in our home county.
- 2
We measure and diagnose on-site. Our technician takes exact measurements of the shape, checks the glass package, inspects the frame, and tells you exactly what failed and why. Background-checked, uniformed, and he’ll introduce himself before he touches anything.
- 3
We give you a written, line-item estimate. You see the cost of glass, hardware, labor, and any sealant or flashing work as separate items. If you already have a written estimate from someone else, bring it. We’ll give you a free second opinion on it.
- 4
Parts decision: OEM or quality aftermarket. If your CGI window is under warranty and OEM parts are required to preserve it, we tell you that plainly. If the warranty’s expired and a proven aftermarket glass package performs identically for less money, we show you both numbers and let you choose.
- 5
The repair or replacement. We remove the old glass or hardware, prep the opening properly, install to CGI’s structural spec, and re-flash and seal with materials rated for South Miami’s rain and sun.
- 6
We test, you inspect, and the Done Right Promise applies. If it’s not right, we come back and make it right. That’s the whole promise. No fine print about “reasonable wear” or “normal conditions.”
What CGI Custom & Geometric Windows Costs in South Miami
Here’s what we charge for the most common CGI shaped-window scenarios in South Miami, so you can price the problem before you even pick up the phone:
- Glass replacement on a half-round or arch window: $420 to $900, depending on diameter and whether it’s laminated impact or standard insulated glass.
- Full-frame replacement of a trapezoid or pentagon window: $800 to $2,400, depending on size, glass package, and frame condition. Oversized openings run higher.
- Hardware replacement (casement stays, hinges, locks on geometric units): $180 to $380 per window, including labor.
- Seal failure repair (defogging or IGU replacement) on a radius window: $340 to $700 per unit, depending on whether we can reuse the existing sash.
- Weep system clearing and sill re-sealing: $140 to $260, often same-day.
What moves the price: the glass package (impact-rated laminated costs more than non-impact), the complexity of the shape (an eyebrow arch with a tight radius costs more to fabricate than a shallow arch), and whether the frame itself has water damage that needs carpentry. We give you the fixed price before we start, and it does not change unless you add scope. Call (850) 930-1813 for a free estimate, and remember: seniors and veterans get 10% off, permanently.
Why South Miami Homeowners Call Winslow Windows & Doors for CGI Work
We’ve been doing this in South Miami since 2011, and Ed Winslow grew up in the Sunset neighborhood, a few blocks from Dante Fascell Park. That’s not a marketing line. That’s where he learned what salt air and summer storms do to windows, and it’s why he started this company: his own family’s house took hurricane damage and nobody could give them a straight answer about their windows. He decided South Miami deserved better.
We install CGI, PGT, CWS, ES Windows, and ECO Window Systems, so when a CGI part is back-ordered or a job makes more sense with a different product, we give you honest options instead of a sales pitch. Every call is answered by a live person, 24/7. Every technician is background-checked and in uniform before he knocks. And every job carries the Done Right Promise. My name’s on the truck. If the work isn’t right, neither am I.
FAQ: CGI Custom & Geometric Windows in South Miami
No. As an independent CGI service provider, we do not void your CGI warranty by servicing or repairing your windows. If your window is under warranty and OEM parts are required for the claim, we use them and document everything. If your warranty has expired, we explain which aftermarket glass and hardware options match CGI’s structural spec and let you decide.
Yes. We template every curved and angled opening precisely, and we order glass cut to that exact template, including eyebrow arches, quarter-rounds, trapezoids, and custom pentagons. We do not adapt stock rectangular glass to a shaped opening. That’s how you get stress cracks and seal failures a year later. Call (850) 930-1813 for a free estimate and we’ll template your windows in person.
Usually not. Fogged glass on a CGI geometric window is seal failure in the insulated glass unit, and most of the time we can replace just the IGU while keeping the existing frame and sash. The exceptions are when the frame has rot or racking, in which case we’ll show you exactly what we found before quoting anything.
Most standard CGI replacement glass and hardware arrive in 7 to 14 days. Custom geometric glass with unusual radii can take 3 to 4 weeks because it’s fabricated to order, not pulled from a shelf. We keep common CGI hardware in stock on our trucks, and we’ll give you a firm timeline when we give you the estimate. That timeline doesn’t slip without a phone call from us explaining why.
No. We price based on the actual labor, glass, and hardware, not the brand name on the frame. In fact, many CGI repairs cost the same as comparable PGT or CWS repairs. We give you a line-item written estimate before work starts, and the price does not change unless you add scope. If you already have a written estimate from another company, bring it to us for a free second opinion. Call (850) 930-1813.
