CGI Custom & Geometric Windows in Fort Lauderdale: What to Know First

We’re Winslow Windows & Doors, an independent CGI service provider in Fort Lauderdale, and we repair, retrofit, and replace custom and geometric CGI windows – arched, radius, trapezoid, hexagon, and oversized configurations included. Most CGI custom-shape jobs in Fort Lauderdale take us 3 to 14 days from diagnosis to completed install, depending on whether the sash needs full replacement or the frame can be salvaged. Pricing starts around $400 for a straightforward custom-shape sash repair and climbs to $4,000+ for a full custom geometric replacement with impact glazing – and we give written line-item quotes before any work begins.

This page is for Fort Lauderdale homeowners who own CGI windows and need someone who actually understands how these specific products behave in our salt air, hurricane seasons, and afternoon downpours. If that’s you, call Ed and the crew at (904) 913-5886 – a live person answers, day or night.

How CGI Products Fail – and How We Fix Them

CGI builds excellent impact windows, but no product is perfect, especially once it’s been through a few Fort Lauderdale summers. Custom and geometric shapes add complexity that standard rectangles never face. Here’s what we see on actual job sites:

• Sentry Series arched-top sashes losing seal at the vertex. The Sentry line’s arched units carry tremendous stress where the curve meets the straight mullion. After a decade of Fort Lauderdale UV and thermal cycling, the sealant at that junction dries and micro-fractures, letting humidity seep between the panes. You’ll see fogging that never clears – and it always starts at the top of the arch. We remove the sash, clean the sightline, apply marine-grade sealant (not the silicone you’d buy at a big-box store), and re-install with fresh setting blocks. If the glass itself has delaminated, we quote a new glazing unit cut to CGI’s exact radius profile.
• Estate Collection trapezoids binding after frame settlement. Trapezoid and parallelogram windows in the Estate line are unforgiving when a wall shifts even a few millimeters. Fort Lauderdale homes on sandy soil settle, and that settlement transfers directly into the custom-shape frame. The symptom is a sash that sticks at one corner or won’t close flush against the weatherstripping. We don’t force the sash and call it fixed – we re-square the frame, adjust the hinge geometry, and often replace the factory glides with a lower-tolerance aftermarket part that allows the window to track cleanly despite minor settlement. OEM glides on these shapes wear quickly once misaligned, which is why this problem tends to get worse fast if ignored.
• CGI WinGuard radius units with failed balances on oversize openings. A six-foot-radius window is heavy, and when the balance system fails on a WinGuard unit, the sash either won’t stay up or slams down when released. This is a real safety concern, and we treat it like one. The fix is replacing the balance assembly with a weight-rated match, then testing the sash at half, three-quarter, and full travel. We see this most often on the larger radius configurations facing Fort Lauderdale’s east-facing exposures – the sun bakes the lubricant dry inside the balance mechanism, and once one side fails, the other follows within months.
• OEM parts lead times vs. our local sourcing reality. CGI is a Miami company, so their warehouse is close – but custom-shape parts still take 2 to 6 weeks when ordered through the manufacturer. We keep a working inventory of the most common radius and angled components for CGI picture and casement units, and for older discontinued shapes we work with two Florida fabrication partners who can replicate CGI’s exact curvature and glass thickness without a brand-marked part number. You get a faster fix without waiting on a shipping manifest. If OEM is your preference, we order it and schedule accordingly – but we always tell you the tradeoff before we ask for a deposit.
• Water staining at the bottom corners of geometric bay units. Bowed-out geometric bays in the CGI Estate and Sentry lines drain through weep channels that are small, and Fort Lauderdale’s summer storms can overwhelm them if the sill slopes even slightly inward. The tell is water stains on the interior drywall at the lowest corners. We re-slope the sill where possible, clean the internal weep pathways, and when warranted, add supplementary drainage on the exterior face that matches the frame color.

Our CGI Custom & Geometric Windows Process

Here’s what happens when you call us about a CGI custom window in Fort Lauderdale:

1. 1
   Call and talk to a person. You reach Ed or a team member who can ask the right questions: What shape is the window? When did you first notice the problem? Is there water, fogging, sticking, or all three? If we can, we’ll give you a rough idea over the phone before we ever put a truck on the road.
2. 2
   On-site diagnostic visit. We measure the exact unit, inspect the glass spec (CGI etches their model and impact rating in a corner of the glazing – we read that etch to confirm which series and which generation you own), and photograph everything we’ll need for accurate quoting. There’s no trip charge if your home is inside our home county.
3. 3
   Written line-item estimate. You get a written estimate that separates parts and labor, lists OEM versus aftermarket options where relevant, and explains the warranty on each path. No verbal estimates that change later. If you already have a written estimate from another company, we’ll review it and give you a free second opinion.
4. 4
   The repair or replacement. Our background-checked technicians arrive in uniform, protect your floors and around the opening, and perform the work using the parts we agreed on. For custom shapes, every cut and every seal is done on-site – we don’t factory-preassemble and hope it fits.
5. 5
   Operational and water test. Every CGI custom or geometric window gets a full open-close-close-lock cycle and a water test before we call it done. If it doesn’t pass, it isn’t done.
6. 6
   Your 36500-Day Done Right Promise. If it’s not done right, we make it right. That’s not a one-year warranty on the parts – that’s Ed Winslow’s standing promise on how we do our work.

What CGI Custom & Geometric Windows Costs in Fort Lauderdale

Here are the ranges we see most often in Fort Lauderdale for CGI custom and geometric window work, updated as of early 2025:

What moves the price: glass thickness and impact rating, the complexity of the radius or angle, whether the frame is salvageable, and access (second-story custom shapes cost more to service safely). Every quote is written and itemized before work starts, and the price on your written estimate is the price you pay – no change orders, no surprises.

Why Fort Lauderdale Homeowners Call Winslow Windows & Doors for CGI Work

We’ve been locally owned and operated since 2011, and Ed Winslow has spent nearly two decades working with Fort Lauderdale’s particular combination of salt air, Atlantic storms, and demanding custom-architecture homes – including plenty of jobs along the Las Olas corridor.

You’re calling the people whose published address and license number you can look up, and whose owner answers the phone. My name’s on the door – literally. That means it gets done right.

We install and service everything from PGT to CWS, ES Windows, and ECO Window Systems as well, which means we never need to fake brand loyalty to close a job. If a CGI custom shape truly isn’t worth saving, we’ll tell you – and we’ll give you the straight comparison against other impact lines we know intimately. Uniformed, background-checked technicians handle every visit. And we answer the phone 24 hours a day, because Fort Lauderdale weather doesn’t wait for business hours, and neither should your window company.
