CGI Custom & Geometric Windows in Fort Lauderdale: What to Know First
We install and replace CGI custom and geometric windows in Fort Lauderdale as an independent CGI service provider. Most measured surveys are scheduled within 48 hours, and the written quote you receive is the same document our technicians work from - no change orders, no surprises. Typical custom CGI jobs in Fort Lauderdale run from $1,800 for a standard geometric replacement to $6,500+ for oversized impact-rated specialty shapes, depending on series and glazing specification.
This page is for homeowners who already own CGI windows and need custom shapes, arched units, or oversized geometric replacements - or who are comparing CGI against other impact-rated lines for a new installation. If you’re researching before contacting a contractor, you’ll find our pricing, process, and failure-mode specifics below. Call (754) 666-7478 to schedule your measured survey, or bring us any written competitor estimate for a free second opinion.
How CGI Products Fail - and How We Fix Them
- Escalade Series fixed geometric units: The thermal break in Escalade’s aluminum frame can separate at the miter joints of trapezoid and hexagonal shapes after 6-10 years of Fort Lauderdale’s salt-air exposure. We’ve traced this to the original silicone back-bed degrading faster on southern exposures within a mile of the Intracoastal. We remove the sash, re-bed the glazing with Dow 795 compatible with CGI’s anodized finish, and replace the thermal break gasket with OEM-spec material rather than generic EPDM.
- Impact-rated radius windows (Sentinel and Estate series): The curved laminated glass in radius-top units sometimes delaminates at the edge first, visible as a milky perimeter band that homeowners mistake for condensation. This is almost always a glazing rebate issue, not glass failure. We re-glaze with the correct PVB interlayer thickness for the specific series - Sentinel uses .090, Estate uses .100 - and document the edge clearance to maintain the Miami-Dade Notice of Acceptance.
- Sparta Series double-hung with custom grilles: The SDL (simulated divided lite) bars on Sparta units can bow inward on units wider than 48 inches, creating a sightline gap that lets water track behind the exterior bar. We see this most in Victoria Park and Coral Ridge homes where the original installer used the standard bar clip instead of the heavy-duty anchor specified for spans over 42 inches. We replace with the correct clip and seal the bar penetration with SikaFlex-221, not silicone.
- Serenade Series casement in geometric configurations: The multi-point lock hardware on Serenade casements drifts out of alignment when the unit is configured as a pentagon or eyebrow shape, because the torque load distributes unevenly across the non-rectilinear frame. Our techs re-map the locking points using CGI’s own striker template rather than field-fabricating shims, which preserves the warranty and prevents the operator arm from stripping the gearbox.
- Estate Collection oversized fixed triangles: On triangles over 60 inches on the base, we’ve found the interior glazing stop can crack at the acute angle corner due to thermal expansion stress concentration. This is a documented issue in south-facing Fort Lauderdale installations where daily temperature swing exceeds 25°F. We upgrade to the reinforced stop extrusion CGI introduced in 2019, available as a retrofit part, and we document the original versus replacement part number in your photo record.
Before
AfterOur CGI Custom & Geometric Windows Process
- 1
Measured survey. We arrive with a printed copy of your original order if available, or we measure the rough opening to 1/16 inch. You keep this document. Sonia Raman reviews every custom geometric survey personally - “measure it right the first time or measure it twice on someone else’s dime.”
- 2
Diagnostics and series identification. We locate the etched mark or label that identifies the CGI series, production date, and original glazing spec. This determines which parts are still available and which have been superseded.
- 3
Parts decision. We quote OEM parts first. If CGI has discontinued a component, we specify the quality aftermarket equivalent that matches the original performance spec, not the closest thing in our van. You see both options in writing.
- 4
Installation. Background-checked, uniformed technicians arrive with license numbers visible. We work from the written scope, photograph each stage, and test every operable unit for air infiltration and lock engagement before cleanup.
- 5
Documentation and guarantee. You receive the photo record, the final invoice matching the quote, and the 365-Day Done Right Promise stamped under Haven Clause 5: No surprises. If the unit doesn’t perform as specified, we return and correct it.
What CGI Custom & Geometric Windows Costs in Fort Lauderdale
These are the ranges we quote in writing for actual CGI custom and geometric work in Fort Lauderdale, based on 2024-2025 measured surveys:
- Standard geometric replacement (triangle, trapezoid, hexagon), non-impact, single glazing: $1,800-$2,800
- Impact-rated geometric, Sentinel or Sparta series, laminated glass: $2,800-$4,200
- Radius-top or arched unit, Estate Collection, impact-rated: $3,500-$5,500
- Oversized fixed geometric (over 72 inches on any dimension), custom marine-grade finish: $4,800-$6,500+
- Re-glazing existing CGI geometric frame (glass and gasket only, frame sound): $800-$1,400
- Hardware realignment or lock replacement on operable geometric casement: $340-$580
What moves the price: the series (Estate runs higher than Sparta), impact rating versus non-impact, whether the original frame is salvageable, and access complexity - second-story geometric units in Harbor Beach or Las Olas Isles sometimes require scaffolding that we specify in the quote, not add later. Call (754) 666-7478 for an exact quote - estimates are free, and we review competitor written estimates at no charge.
Why Fort Lauderdale Homeowners Call Sightline Windows & Doors Fort Lauderdale for CGI Work
We’ve installed and serviced CGI products since 2012, but we also specify PGT, CWS, ES Windows, and ECO Window Systems when the opening calls for a different performance tier or price point. That multi-brand fluency means we diagnose CGI failures against what we’ve seen across comparable lines, not in isolation.
Every technician is background-checked and uniformed with license number visible - Haven Clause 3, Verified Crews. The 365-Day Done Right Promise is written into every contract, not offered as a courtesy after the fact. And the measured survey you keep, the written price before any work starts, and the documented photo record on completion are standard on every job, not upgrades.
Our phone is answered by a live person, 24/7. If you’re comparing CGI against other impact-rated custom window options for a Fort Lauderdale home, we’ll walk through the specifications without pushing toward any single manufacturer.
FAQs
No, provided the work is performed to CGI’s installation standards and uses OEM or equivalent-spec parts. CGI’s warranty covers manufacturing defects, not installation. We document every part number and installation detail so that if a manufacturing issue arises, your claim is supported by evidence, not contradicted by sloppy fieldwork. Call (754) 666-7478 if you’d like us to review your warranty documents before scheduling.
Standard geometric frames and sashes typically ship in 4-6 weeks from CGI’s Miami-area distribution. Discontinued series parts or custom marine anodized finishes can extend to 8-10 weeks. We quote the lead time in writing with your price, and we don’t collect deposit until you confirm the timeline works. Call (754) 666-7478 for current availability on your specific series.
Repair makes sense when the frame is sound and the failure is isolated to glass, gasket, or hardware - typically 30-50% of replacement cost. Replacement is the better value when the frame has thermal break separation, the glazing rebate is corroded, or the series has been discontinued and parts are scarce. We assess both paths during the measured survey and quote each so you can compare. Call (754) 666-7478 to schedule.
We can match sightline dimensions, frame depth, and exterior profile closely enough that the difference is not visible from the curb, but we won’t claim exact color match across manufacturers. We bring sample chips to the survey and photograph them against your existing frame in natural light. The final specification is your approval, not our assumption. Call (754) 666-7478 to arrange a comparison.
Yes, for any replacement that changes the opening dimension or the impact rating. Fort Lauderdale Building Services requires a permit for impact-rated window installations in the High Velocity Hurricane Zone, and we pull and close those permits as part of our scope. The permit number appears on your final documentation. Non-impact like-for-like replacements in some interior zones may not require permitting; we verify this during survey and tell you in writing either way. Call (754) 666-7478 for specifics on your property.
