CGI Custom & Geometric Windows in Miami: What to Know First
We service and repair CGI custom and geometric windows throughout Miami, including arched, radius, trapezoid, and oversized impact units. Most service calls are handled in a single visit, and we carry or can source the specific hardware, glass packs, and weatherstripping these shaped windows need. Pricing is straightforward: you pay a diagnostic fee upfront, we apply it toward the repair if you proceed, and you get a written line-item quote before any work begins. Call (561) 956-2754 and a live person answers, day or night.
This page is for homeowners who already own CGI windows and are dealing with a problem in a custom or geometric opening: a fogged radius unit, a trapezoid that won’t seal, an arch window that binds in the frame, or an oversized impact window with a failing track. If that sounds familiar, the sections below explain what’s actually going wrong and how we address it.
How CGI Products Fail - and How We Fix Them
CGI builds a solid product line, but Miami’s salt air, humidity, and storm cycles expose weak points over time, especially in shaped and oversized glass. Here’s what we actually see on service calls, with the series names where they apply.
- Fogged glass in radius and arched units (CGI Estate Collection). The bent-glass seals on arched and radius insulated units take more thermal expansion than flat glass. In Miami, a south-facing arch window can cycle through temperature swings of 40 degrees in a single afternoon, and the seal flexes until it fails. We replace the insulated glass pack, not the whole sash, and register the glass warranty with CGI before we leave the driveway.
- Trapezoid and parallelogram windows that won’t close square (CGI Targa series). Shaped frames rely on precise corner joinery. When a trapezoid window is 10 or 15 years old, the frame corners can work loose, and the sash drops a degree or two out of square. The window looks fine from street level but won’t latch. We disassemble the frame, re-square the corners with factory-spec fasteners, and reset the sash so it seats cleanly against the weatherstripping.
- Oversized horizontal sliders that bind on the track (CGI Estate and Estate Deluxe lines). A 12-foot or 16-foot impact slider carries serious weight. The rollers wear unevenly, and the track picks up a fine mix of salt and sand that grinds the bearings down. The window gets hard to move, then binds entirely. We replace the roller assemblies with load-rated parts matched to the panel weight and clean the track channels with the sash out of the frame, not just wiped down from above.
- Weep-hole blockage in geometric fixed windows (CGI 2100 single-hung and fixed shapes). In a heavy Miami downpour, water that can’t drain through the weep holes pools inside the frame and finds its way to the interior. Hexagonal, octagonal, and circle-top fixed windows are the most common culprits because their weep paths follow the shape of the frame and clog at the corners. We clear the original drain paths, verify they’re not painted over from a past refinish, and test the frame with water before we put the trim back.
- Impact glass delamination in older CGI laminated units. Impact windows use a plastic interlayer between glass layers. In coastal Miami exposure, edges of that interlayer can delaminate if the original edge seal was cut too close or damaged during install. The glass doesn’t crack, but you see a milky haze spreading inward from the frame edge. This is a glass-pack replacement, not a repair, and we order the replacement from the OEM where available or a Miami-certified partner fabricator when the original line has been discontinued.
Our CGI Custom & Geometric Windows Process
Every CGI shaped-window job follows the same sequence, whether it’s a fogged arch in Coral Gables or a binding trapezoid in Kendall. It’s methodical on purpose.
- 1
Call and describe the problem. A live person answers at (561) 956-2754. We ask about the window shape, the symptom, and the age of the unit, then schedule the diagnostic visit.
- 2
On-site inspection and measurement. The technician measures the frame, the sash, and the opening itself, then inspects the glass, hardware, and weatherstripping. Every opening is measured twice.
- 3
Parts decision: OEM or matched aftermarket. For active warranty work, we source CGI OEM parts where available. For out-of-warranty windows where OEM has been discontinued, we use aftermarket parts matched to the original spec, and we show you the differences on paper before ordering.
- 4
The repair or replacement, done in place. For glass-pack work, we remove the sash or the direct-set glass, install the new pack, and reset the seals. For frame work, we re-square, refasten, and reseat. We protect the surrounding trim and clean up as we go.
- 5
Test and verify. We cycle the window, check the latching, run water over the track where applicable, and confirm the drainage paths move water the way they should.
- 6
Warranty registration and the 90-Day Done Right Promise. If the repair involves new glass or frame components with a manufacturer warranty, we register both warranty layers in writing and hand you the paperwork before the truck leaves. Our workmanship is covered for 90 days, no arguing.
What CGI Custom & Geometric Windows Costs in Miami
Costs vary by the window’s shape, the failure type, and whether the unit is still under warranty. Here’s what we’ve charged on recent Miami jobs, as line-item ranges, so you have a real number to work from.
- Resealing or cleaning a fogged radius or arch unit: $280-$650 depending on glass size and whether sash removal is required.
- Full glass-pack replacement for an arched or geometric CGI window: $700-$1,700 depending on dimensions, glass thickness, and whether the original line is still in production.
- Track and roller replacement on oversized CGI sliders: $350-$900 depending on panel count and roller type.
- Frame re-squaring for binding trapezoid or parallelogram windows: $400-$1,100 depending on frame condition and access.
- Weep remediation and drainage testing on fixed geometric windows: $180-$450.
What moves the price: glass area, whether we’re working on an upper floor, whether the original line is discontinued, and whether the failure is isolated or widespread across multiple panes. You’ll have a written quote before we order anything. Call (561) 956-2754 to schedule a free estimate, and we’ll apply the diagnostic fee toward the repair if you proceed.
Why Miami Homeowners Call TruePane Windows & Doors for CGI Work
We’re an independent CGI service provider, not a factory installer, and that independence matters when a window is out of warranty and the manufacturer’s answer is “replace the whole unit.” We’ll tell you honestly whether a repair makes sense or whether replacement is the better spend. Dale Kessler started this company in 2008 with a rule that’s still on the whiteboard: if the pane is not true, the job is not done.
Beyond CGI, our techs work on PGT, CWS, ES Windows, and ECO Window Systems, so when a Miami home has mixed brands across different openings, one call covers all of them. Every job is backed by the 90-Day Done Right Promise and The Keystone Standard: both warranty layers registered in writing, durations stated, before the truck leaves the driveway. We’ve served Miami’s homeowners for over a decade, and we plan to be answering the phone here in thirty years.
FAQs
In most cases we replace the glass pack only, not the frame, which saves you 40-60% over a full unit replacement. For a fogged arch, a delaminated impact pane, or a blown seal in a radius window, the frame is usually fine and the glass pack is the fix. We assess the frame condition on site and tell you before any work begins. Call (561) 956-2754 for an exact quote.
No, not when it’s done with OEM parts on an active warranty claim, or with matched aftermarket parts on an out-of-warranty unit. We document every part number and register warranty layers in writing before we leave. That’s part of The Keystone Standard we’ve applied to every job since 2008.
Yes. We maintain relationships with Miami glass fabricators and parts distributors who carry CGI-compatible hardware, including bent glass, custom radius weatherstripping, and load-rated rollers. When OEM parts are discontinued, we source matched alternatives and show you the spec sheet before we order.
Most glass-pack replacements, track repairs, and weep remediations are finished the same day. If we’re waiting on a custom glass order for an unusual radius or a discontinued shape, expect 7 to 14 days from order to install. We’ll tell you the timeline before you approve the work.
Replace when the frame is rotted or bent, when the original line was discontinued and no matched aftermarket glass exists, or when the cost of repair exceeds 50% of a new unit. Otherwise, repair is usually the better spend. We’ve been honest about this with Miami homeowners for over a decade, and we’ll give you the same straight answer on your window.
