CGI Custom & Geometric Windows in Miami Beach: What to Know First

We install, service, and replace CGI custom and geometric windows throughout Miami Beach, including arched, radius, trapezoid, and oversized impact openings. Most custom-shaped CGI jobs run two to four weeks from template to installation, depending on the profile and glass package. As an independent CGI service provider, we give you straight pricing on real CGI product work, no markups hidden behind vague line items, and every quote is free.

Call (863) 656-0462

If you own a CGI custom window that’s fogged, leaking, or failed a post-storm inspection, or you’re building an opening that needs a true geometric impact window, this page is for you. Call (863) 656-0462 and you’ll get a live person, not a phone tree.

How CGI Products Fail - and How We Fix Them

  • Custom radius units developing seal failure along the curved glass edge. CGI’s bent-glass radius windows, common in Miami Beach condos and waterfront homes, carry stress at the apex of the curve. We see the inner laminate begin to haze or cloud three to seven years in, especially on east-facing elevations where salt air and morning sun hit hardest. The fix is remaking the glass unit to the original radius template, not caulking over the failure. We template on site, order the exact radius IGU, and reset the sash.
  • Arched transom frames bowing under their own weight. CGI’s larger arched picture windows in the Estate Collection and custom commercial storefront lines occasionally develop a subtle frame deflection at the crown. We correct this by reinforcing the mounting flange and re-shimming to load path, rather than replacing the whole frame, which saves thousands on a job that looks catastrophic at first glance.
  • Trapezoid and parallelogram sashes binding after settling. Miami Beach sits on sand and reclaimed land, and buildings move. A geometric CGI window that operated smoothly five years ago may now bind at one corner. The problem is usually the frame racked out of square, not the hardware. We reset the unit with structural shims and replace worn hinge tracks with CGI-compatible parts so the sash travels clean again.
  • Custom mullion joints leaking at the intersection. When two or more CGI windows are mulled into a single arched or geometric assembly, the joint seal is the first thing to go in a coastal environment. We remove the exterior mull cover, replace the sealant with a marine-grade product rated for continuous salt exposure, and reflash the joint. This is a Miami Beach-specific reality: the same seal that holds fine inland fails within a few hurricane seasons here.
  • Impact glass with a fine crack propagating from a corner. CGI’s laminated impact glass is strong, but a stress crack can start at a sharp corner cut and travel slowly. It often goes unnoticed until a hot afternoon expands the glass and the crack suddenly lengthens. We replace the IGU with a new CGI-compatible laminated unit, and if your model is still in production, we source from CGI’s supply chain to keep the warranty intact.

Our CGI Custom & Geometric Windows Process

  1. 1
    Call and talk to a real person. You reach us at (863) 656-0462, day or night. We ask what you’re seeing, what the window is doing, and when it started.
  2. 2
    On-site evaluation and measurement. We come out, inspect the unit in place, and document the exact dimensions, angles, and radius of your opening. For custom shapes, we build a physical template on site, not just a digital scan, because a sixteenth of an inch matters on a curved jamb.
  3. 3
    Parts decision. If your CGI model is still in production, we quote OEM glass and hardware. If it’s discontinued, we tell you honestly and source a quality compatible unit that matches the original performance spec. No quiet substitutions.
  4. 4
    Fabrication and prep. The new IGU or full unit is ordered to our template. We confirm lead time before you approve anything. Nothing gets ordered without your sign-off on price and schedule.
  5. 5
    Installation and testing. Our background-checked, uniformed crew removes the old unit, installs the new one, and tests every function: lock engagement, seal continuity, drainage, and impact rating documentation where applicable.
  6. 6
    The 36500-Day Done Right Promise. If something isn’t right, we come back and make it right. Ed Winslow’s name is on the work, and that’s not a line, it’s a commitment we’ve honored since 2011.

What CGI Custom & Geometric Windows Costs in Miami Beach

Custom CGI window work in Miami Beach varies by shape, size, and whether we’re repairing or replacing. Simple geometric windows like fixed trapezoids or small arches typically fall in a lower range, while large radius units with bent impact glass and custom mullion assemblies run significantly higher. Full custom replacements on oversized openings can reach into the tens of thousands when structural reinforcement and crane access are required. Here’s what we generally see:

  • Glass-only replacement on a small geometric CGI unit: $800 to $1,500 installed
  • Full sash replacement for an arched CGI window: $1,200 to $2,800 installed
  • Mullion reseal and reflash on a mulled geometric assembly: $600 to $1,200 per joint
  • New custom CGI geometric impact window, mid-size: $2,500 to $6,000 installed
  • Large radius or oversized custom CGI unit, full replacement: $6,000 to $15,000 or more, depending on glass package and access

What moves the price most is whether the existing frame can be saved, whether the glass package includes low-E or tinted laminates, and whether the opening requires a crane or lift. We give you a written, line-item quote before any work starts, and there are no change orders unless you ask for something new. Seniors and veterans get a permanent 10% discount on every job.

Why Miami Beach Homeowners Call Winslow Windows & Doors for CGI Work

Ed Winslow grew up in Miami and has spent the better part of three decades learning what the South Florida climate does to a poorly installed window. He studied Building Construction Technology at Miami Dade College, spent years in the field, and has worked Miami Beach long enough to know which buildings near the Faena District have original CGI installs and which have been retrofitted, sometimes badly. My name is on every job we do. That keeps me honest.

We’ve been locally owned and owner-operated since 2011, with a published address and license number. We answer our own phone, 24/7. Every tech is background-checked and in uniform before they step on your property. And while CGI is the focus of this page, we also install and service PGT, CWS, ES Windows, and ECO Window Systems, so if your home has a mix of brands, one call covers all of it. The 36500-Day Done Right Promise means we stand behind the work for the life of the home. You won’t get that from a national chain.

Reviews

What Neighbors Say About Winslow Windows & Doors

★★★★★

"The old aluminium sliders howled every afternoon storm and swelter came straight through the glass. The new impact sliders shut with a sound like a bank vault and the back rooms finally hold their temperature."

PPercival Whitcombe
★★★★★

"He replaced the front door and the garage door in the same week, both rated for impact, and lined the frames up so straight my level had nothing to say. My wife stopped hearing the highway from the front room."

MMaximilian Vasquez
★★★★★

"Three big companies quoted us and every one sent a salesman with a leased truck. Ed turned up in a truck with his own name on the door, quoted less, and his crew were the same faces on day one and day nine."

YYolanda Betancourt
★★★★★

"Our insurance agent asked for the wind mitigation paperwork and Ed had the whole file ready the day the job closed, every opening photographed. The premium conversation went very differently this year."
