AfterCGI Custom & Geometric Windows in West Park: What to Know First
We provide independent CGI custom and geometric window service in West Park, with most measured surveys scheduled within 48 hours and written quotes delivered before any work begins. Custom CGI shapes - arched, round-top, trapezoid, and oversized geometric units - typically run $1,800 to $4,500 installed depending on the series and whether the opening requires structural modification. This page is for West Park homeowners who already own CGI products or are specifying them for a renovation, and need a technician who understands the difference between a Series 375 fixed geometric and a Series 550 architectural shape. Call (786) 685-4706 to schedule your measured survey. The price we write is the price you pay.
How CGI Products Fail - and How We Fix Them
- Series 375 geometric fixed units: seal failure in the thermal break. The aluminum thermal break in these custom shapes can separate at the mitered corners where the factory weld meets the geometric cut. We see this in West Park homes built during the 2015-2019 window boom, especially on south-facing gables where daily expansion cycles stress the corner joint. We replace with OEM thermal-break extrusion or, when CGI lead times stretch past 12 weeks, a verified aftermarket equivalent that matches the original U-factor and SHGC ratings.
- Series 550 architectural shapes: laminated glass delamination at the radius. Curved and arched CGI units use heat-formed laminated glass that can develop edge delamination where the PVB interlayer meets the curved cut. The symptom is a cloudy perimeter that homeowners mistake for seal failure. We diagnose this with a polarized light check - a tool most glass shops don’t carry - and source radius-matched replacement lites through our CGI parts channel or, when necessary, custom-laminate to the original thickness specification.
- Series 301 impact geometric units: corner key stress cracking in oversized openings. Custom geometric windows over 60 inches on any side in the Series 301 line rely on internal corner keys that can fatigue under repeated hurricane-season pressure cycling. West Park’s location near the coast means these units see more negative pressure events than inland Broward County homes. We reinforce with structural silicone bedding and, on replacements, upgrade to the Series 375 corner-key geometry if the frame depth allows.
- Custom color anodized frames: chalking and finish degradation. CGI’s Dark Bronze and Black anodized finishes on custom shapes can chalk prematurely when the clearcoat breaks down under UV exposure. This is cosmetic until the anodic layer itself degrades, at which point the aluminum begins to pit. We assess remaining anodic thickness with an eddy-current gauge and match replacement frames to the original lot color using CGI’s archived finish codes - or coordinate a factory-refinish order when the lot code has been discontinued.
- Geometric operating units: sash warpage in trapezoid and pentagon shapes. CGI’s custom operating geometric windows use a heavier sash profile that can rack out of square if the original installation didn’t include proper shimming at the hinge side. The tell is binding at the lock or daylight visible at the weatherstrip. We measure the diagonal deviation, then either re-shim the existing sash or specify a replacement with reinforced hinge bosses - a running change CGI introduced around 2019 that many West Park homes predate.
Our CGI Custom & Geometric Windows Process
- 1
Measured survey and documentation. Sonia Raman or a licensed technician arrives with a laser measure, level, and the CGI spec binder for the series in question. You keep the measured drawing; we keep the photocopy. Haven Clause 1: Have it in writing.
- 2
Failure-mode diagnosis. We test operability, check glass edge condition with polarized light, and record frame readings including anodic thickness where relevant. The findings go on the same document as the quote.
- 3
Parts decision: OEM, verified aftermarket, or custom fabrication. We log the CGI part number, check current availability, and present options with lead times and warranty implications. No surprises.
- 4
Installation or repair under the Haven Standard. Verified crew, license number provided before arrival, uniformed technician. We photograph before, during, and after. Evidence on every job.
- 5
Operational test and final documentation. Every moving part is cycled, every seal is smoke-tested, and the photo record is uploaded to your job file. The invoice matches the quote. The 365-Day Done Right Promise is stamped and dated.
- 6
Cleanup and sign-off. We leave the work area as we found it, with the documented photo record, written warranty, and your copy of the original measured survey in hand.

Why West Park Homeowners Call Sightline Windows & Doors West Park for CGI Work
We’ve worked the residential streets near Sunview Park long enough to know which West Park homes carry original 1980s single-pane aluminum that was retrofitted with CGI in the mid-2010s, and which were built new with Series 375 or 550 from the start. That history matters when you’re diagnosing why a geometric unit is leaking at the corner - the rough opening may have settled in ways a tech from Orlando wouldn’t recognize.
Our technicians are background-checked, uniformed, and identified by license number before they arrive - Haven Clause 3. We carry eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - so if your CGI custom window is discontinued or the lead time doesn’t work, we can specify an equivalent from another line with comparable performance numbers, not whatever we have in the warehouse.
The 365-Day Done Right Promise is written into every job, not offered as a favor. And the price on the page - or in your written quote - is the price on the invoice. Measure it right, say what it costs, do the work.
FAQs
Using an independent service provider like Sightline does not automatically void a CGI warranty, but warranty coverage for the specific repair depends on the age of the unit and whether the failure is a manufacturing defect or installation-related. We document our findings with photos and written assessment so you have evidence if a warranty claim is appropriate. For units still under CGI’s original 10-year limited warranty, we can coordinate the claim or perform the repair and provide documentation for reimbursement. Call (786) 685-4706 and we’ll review your serial number and failure mode at no charge.
Standard geometric extrusions and glass packages typically ship in 4-6 weeks from CGI’s Hialeah facility; custom radius laminates or discontinued finish colors can extend to 10-14 weeks. We maintain relationships with regional distributors and, when lead times are unacceptable, can source verified aftermarket equivalents or specify a compatible unit from PGT, CWS, or ES Windows. We tell you the real lead time in the written quote, not after you’ve signed. Call (786) 685-4706 for current availability on your specific series and shape.
Most arched and curved CGI units can be reglazed - the glass replaced while retaining the original frame - provided the frame extrusion is sound and the thermal break is intact. We remove the sash, measure the exact radius and lite thickness, and order replacement glass to the original CGI specification. If the frame has corner-key fatigue or anodic degradation, we’ll tell you before ordering glass and give you the price for both repair and full replacement. Call (786) 685-4706 to schedule a diagnostic; the assessment is free.
Yes, when the job involves structural modification or when the original installation was not permitted and the city requires documentation for the replacement. West Park falls under Broward County building code, and impact-rated replacements must meet the HVHZ (High Velocity Hurricane Zone) requirements that govern our coastal location. We pull the permit, schedule inspections, and pass them - included in the written scope, never added later. Call (786) 685-4706 and we’ll confirm whether your specific job triggers permit requirements.
We replace rather than repair when the frame is structurally compromised, the series has been discontinued with no parts path, or the repair cost exceeds 60% of replacement. For most Series 375 and 550 units under 15 years with isolated seal or hardware failure, repair is the better value. We make this recommendation in writing with both prices, and we don’t charge for the assessment. Call (786) 685-4706 to schedule your free evaluation.
