CGI Custom & Geometric Windows in Fort Myers: What to Know First
We’re an independent CGI service provider in Fort Myers, and we handle custom and geometric window jobs that most shops won’t touch: arches, radius tops, trapezoids, octagons, and oversized openings. Most CGI custom window work in Fort Myers runs $650-$2,800 per opening depending on glass package, frame finish, and whether we’re repairing or replacing the unit. We quote upfront, line by line, and we don’t change the number once we’ve started. If you own a CGI window that’s lost its seal, cracked at a miter joint, or never fit right from the day it was installed, call (239) 453-7751. This page is for Fort Myers homeowners who want straight answers about their CGI windows, not a sales script.
How CGI Products Fail - and How We Fix Them
CGI builds a serious impact window. But after 15 years of working on Fort Myers homes, we’ve learned exactly where these units show their age. Here’s what we see most often:
- Miter-joint separation on geometric frames. Trapezoids and octagons put stress at the corners where the aluminum frame pieces meet. On CGI’s Estate Collection and Sentinel lines, that miter can open up after years of thermal expansion and hurricane cycles. The corner key loosens, the joint gaps, and water finds a way in. We disassemble, re-key, and reseal the corner rather than slapping caulk over it and calling it done.
- Seal failure on radius-top and arch units. Curved glass is more prone to seal breach at the apex of the curve because the laminated interlayer and the spacer bar flex at different rates. We’ve replaced dozens of failed IGUs on CGI arched windows in Fort Myers, and we always match the original glass tint and Low-E coating so the new unit doesn’t stand out against its neighbors.
- Hardware wear on hinged geometric windows. CGI’s casement and awning lines use stainless steel operators, but the nylon rollers and slide bars wear down in salty Gulf air faster than the metal parts. When an octagon awning won’t stay open or cranks hard, it’s almost always the roller set, not the operator itself. We stock replacement rollers and slide bars for most CGI casement and awning models.
- Improper shimming from the original install. A custom geometric window that was installed with uneven shimming will bind, leak, or crack at the glass during settling. This is common in older Fort Myers ranch homes off McGregor Boulevard where slabs have shifted over decades. We pull the trim, re-shim the frame square, and reset the window so it operates the way CGI engineered it.
- Water intrusion at oversized opening transitions. On CGI fixed windows and large picture units, the flashing detail between the frame and the rough opening is where most leaks happen. Fort Myers gets 55+ inches of rain a year and the summer afternoon storms are relentless. If the original installer skipped peel-and-stick flashing or taped it wrong, water wicks into the sill plate. We pull the unit, re-flash properly, and reseat the window.

What CGI Custom & Geometric Windows Costs in Fort Myers
We quote per opening, not by some bundle formula you can’t see. Here’s what you’re generally looking at for CGI custom and geometric work in Fort Myers:
- IGU (insulated glass unit) replacement on an arched or radius-top CGI window: $650-$1,400 depending on glass size, tint, and whether it’s a laminated impact unit.
- Miter-joint repair on a geometric frame (trapezoid, octagon, or triangle): $180-$425 per corner, including disassembly, re-keying, and resealing.
- Hardware replacement (rollers, slide bars, operators) on a CGI casement or awning geometric window: $140-$360 per window, parts included.
- Flashing remediation and reset on an oversized fixed or picture CGI unit: $400-$950 depending on access and how much trim we have to pull.
- Full replacement of a custom geometric CGI window (new frame, impact glass, install): $1,800-$4,500+ per opening, and the sky’s the limit for truly custom shapes and finishes.
What moves the price: glass package (single vs. laminated impact), Low-E or tinted coatings, frame finish, access difficulty, and whether we’re repairing or pulling a permit for full replacement. Call (239) 453-7751 and we’ll give you an exact number before any work starts. Estimates are free.

FAQs
Using aftermarket parts can void the remaining CGI warranty on that specific component, which is why we discuss OEM versus aftermarket options with you before we order anything. For glass replacements, we match the original specification so the unit performs identically. If your window is still under CGI’s warranty, we’ll help you understand what’s covered and whether a manufacturer claim is the better path.
Most hardware repairs and miter-joint fixes are done in a single visit, typically 1-3 hours on site. Glass replacements take longer because we order the IGU to match your original tint and coating; that’s usually 7-14 days from order to installation. Call (239) 453-7751 and we’ll tell you what to expect for your specific window.
Yes. We measure the existing unit, confirm the CGI model line if it’s still identifiable, and order a replacement with matching glass, frame finish, and mull profile. If the line has been discontinued, we’ll show you the closest available match and get your approval before ordering. The goal is a window that doesn’t look like an obvious patch.
Most CGI leak repairs in Fort Myers run between $180 and $950 depending on whether it’s a failed seal, a bad miter joint, or a flashing problem at the rough opening. We’ll tell you the exact cause and the exact price before any work begins. Estimates are free, and seniors and veterans always get 10% off.
For full window replacements that require a permit under Lee County or City of Fort Myers code, we pull the permit and the job gets inspected. For like-for-like glass or hardware repairs, permits typically aren’t required. We’ll tell you which applies to your job before we start.
