CGI Custom & Geometric Windows in Miami Beach: What to Know First
We repair and replace CGI custom and geometric windows across Miami Beach, including arched, radius, trapezoid, and oversized impact units. Most service calls are scheduled within a few days, and we give you a written line-item quote before any work begins. If you own a CGI window that is fogged, binding, leaking, or failed after a storm, call (386) 406-9359 and a live person will answer.
This page is for Miami Beach homeowners who already have CGI windows or are planning a build that calls for shaped openings. CGI builds a strong product. But shaped windows in salt air behave differently than rectangular ones, and the fixes are not always what the spec sheet suggests. We are an independent CGI service provider, not a CGI dealer, which means we are free to tell you when a repair makes sense and when replacement is the honest call.
Key Takeaways
- CGI custom and geometric windows are worth repairing when the frame is sound and the glass is intact.
- Shaped units fail at the radius points and at the frame-to-glass bond more often than rectangular sashes.
- We quote OEM and quality aftermarket parts side by side so you see the cost difference on paper.
- Every job is backed by our Done Right Promise and both warranty layers registered in writing.
How CGI Products Fail - and How We Fix Them
CGI makes a heavy, well-engineered window. The failures we see in Miami Beach are rarely a matter of cheap manufacturing. They are a matter of geometry, salt, and time. Here is what shows up most often on custom and geometric CGI units.
- Radius seal separation on arched units. CGI’s Estate Collection and Targa series arched windows flex at the crown more than a square unit ever will. After enough thermal cycles, the seal between the glass and the frame pulls away at the top of the radius. You will see condensation that comes and goes, or a faint white haze along the curve. We remove the sash, clean the channel, reset the seal with the correct bedding compound, and re-square the unit in the opening. Silicone smeared over the crack is not a repair; it buys a season.
- Frame racking on oversized geometric openings. A fixed trapezoid or pentagon window carries wind load differently than a venting rectangle. On homes along the Venetian Causeway and North Beach, we regularly see CGI frames that have racked a quarter-inch out of true because the original install relied on shims instead of a structural header inspection. The glass does not break; the frame twists, and the window starts to bind or leak at the bottom corner. We pull the unit, correct the opening, and reset it with continuous bearing, not a stack of cedar shims.
- Roller and track wear on CGI sliding windows in geometric frames. The CGI Estate slider and Estate II lines use a stainless roller assembly that holds up well, but the track collects salt and sand from the ocean breeze. After a decade, the rollers grind flat and the panel drags. On a rectangular window this is annoying. On a shaped unit with a non-square track, a dragging panel puts sideways pressure on the frame and accelerates seal failure. We replace rollers with the correct CGI-spec part, clean and true the track, and adjust the panel so it rides square.
- Laminated glass delamination at exposed corners. CGI impact glass is a laminated sandwich, and on triangle and octagon windows the exposed corner is the vulnerable point. Salt moisture works into the edge and the layers begin to separate, showing up as a milky bloom along the corner. This is more common on older CGI units from the mid-2000s. If the delamination is confined to the edge and the structural interlayer is intact, the glass can often be saved. If it has crept more than an inch into the sightline, the lite needs replacement. We will tell you which one you have before any money changes hands.
- Weep system blockages on custom-shaped fixed windows. Fixed geometric windows still need to drain. On CGI’s Sentinel and Estate fixed units, the weep holes are small and positioned for a rectangular install. When a builder orders a custom shape, the weeps sometimes end up in the wrong place, or get buried in stucco during install. Water then sits in the lower channel, and over time you get mineral staining, a soft frame at the bottom corner, or corrosion on the hardware. We clear the blocked weeps, add drainage where the geometry requires it, and reseal the sill with a marine-grade sealant.
Our CGI Custom & Geometric Windows Process
Every CGI job we take in Miami Beach follows the same sequence. No shortcuts, no surprises.
- 1
Call and describe the problem. A live person answers, day or night, and records what you are seeing. We will ask about the window’s age, shape, and where the problem shows up.
- 2
On-site inspection. A background-checked, uniformed technician measures the opening twice, checks the frame for true, and identifies the failure point. If it is a shaped unit, we inspect the radius points and the header above the window. Dale Kessler himself reads the opening on most shaped units because that is where installs go wrong most often.
- 3
Written quote with parts options. We put OEM and quality aftermarket parts on paper side by side, with prices, so you can see exactly what you are buying and why. If the unit is too far gone, we tell you and quote replacement instead.
- 4
The repair or replacement. We remove the sash or the full unit, make the structural correction if the opening is out of true, and set the window with continuous bearing. We register both manufacturer warranty layers in writing before we leave the driveway.
- 5
Testing and cleanup. We cycle the unit, check the seals, and clean the job site. If it is not right in the opening, it is not right, and we do not leave until it is.
- 6
Done Right Promise. If anything we touched fails within 90 days, we come back and make it right. No paperwork fight, no fine print.
What CGI Custom & Geometric Windows Costs in Miami Beach
Here are honest ranges for the CGI work we do most often in Miami Beach. These are starting figures based on jobs we have completed in the last two years. Your exact number depends on access, the age of the unit, and whether the opening needs structural correction.
- Seal repair on an arched or radius CGI window: $180-$340 per unit
- Roller and track service on a CGI sliding window: $120-$260 per panel
- Full sash reglazing on a geometric fixed unit: $400-$900 per lite depending on glass type and size
- Frame reset and reinstallation of a racked shaped unit: $600-$1,400, more if the header needs reinforcement
- Full replacement of a custom CGI impact window: $1,800-$5,000+ depending on size, shape, and impact rating
What moves the price is whether we can save the existing frame, whether the opening is still true, and whether the glass is a standard CGI laminate or a custom radius profile. We quote on paper before we start, and the number we quote is the number you pay. Call (386) 406-9359 to schedule a free estimate.
Why Miami Beach Homeowners Call TruePane Windows & Doors for CGI Work
We have been serving Miami Beach and nearby communities since 2008 through a family craft tradition, not a franchise playbook. Our founder, Dale Kessler, grew up in Normandy Isles and learned the hard way what salt air does to a poorly sealed frame. Our technicians are trained in-house, background-checked, uniformed, and they work in your home the way they would work in their own mother’s.
We are an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. That matters when a CGI repair does not make economic sense and you need a side-by-side comparison of PGT, CWS, ES Windows, or ECO Window Systems. We will show you the options on paper and help you choose without pushing you toward the brand that pads our margin.
Every job we do carries the Done Right Promise and The Keystone Standard: both warranty layers registered in writing, durations stated, before the truck leaves the driveway. A live person answers the phone 24 hours a day, 7 days a week. If the pane is not true, the job is not done. That is the founding rule, and it governs every CGI window we set in Miami Beach.
FAQs
No, not when the work is done correctly with parts that meet CGI’s specifications. We register both manufacturer warranty layers in writing on every job, and we document the parts used. If an OEM part is required to preserve warranty coverage, we tell you and quote it accordingly. We also offer quality aftermarket options where the OEM part is discontinued or backordered, and we mark that clearly on the written quote.
In most cases, yes. We can source OEM parts for CGI lines dating back to the mid-2000s, including the Estate, Targa, Sentinel, and Estate II series. For discontinued shapes where the OEM part is no longer made, we work with reputable glass fabricators who cut custom radius and trapezoid lites to match. If a part is truly unobtainable, we will tell you on the first visit, not after we have taken the window apart. Call (386) 406-9359 with your window’s model and year, and we will check parts availability before scheduling.
If the frame is sound, the opening is true, and the glass is intact, repair is usually the right call and costs far less than replacement. If the frame is racked more than a quarter-inch, the laminated glass has delaminated into the sightline, or the unit is more than 20 years old with multiple failed seals, replacement is the honest recommendation. We will show you the numbers for both options and let you decide. We do not push replacement because it is a bigger invoice.
Most seal, roller, and hardware repairs are completed in a single visit, usually 1.5 to 3 hours depending on the unit. Full frame resets on shaped openings take longer, typically a half day to a full day, because we correct the opening structure before resetting the window. You will know the timeline before we start, and we will be there when we say.
Yes. When a repair involves changing the structural bearing of an oversized opening or replacing a header, we pull the permit and schedule the inspection. We do not do structural work on the quiet, and we do not leave a homeowner holding an unpermitted alteration. The permit cost is listed on your quote as a line item.
