CGI Custom & Geometric Windows in Jupiter: What to Know First

As an independent CGI service provider, we measure, order, and install CGI custom and geometric windows across Jupiter with written prices delivered before any work starts and a 365-Day Done Right Promise on every job. Most CGI custom window installations in Jupiter run 4-6 weeks from measured survey to final install, with shaped and oversized units sometimes extending to 8 weeks depending on glass tempering schedules. We do not guess at prices; Haven Clause 1 means the measured survey you keep and the written quote are the same document, with no change orders on invoice day.

This page is for Jupiter homeowners who already own CGI products or are specifying them for new construction or replacement, particularly for arched, curved, geometric, or oversized openings where standard rectangles will not work. If you are comparing CGI against PGT, CWS, ES Windows, or ECO Window Systems for a custom opening, we specify by performance and price, not by what is in stock. Call (772) 362-5402 to schedule your free estimate.

How CGI Products Fail - and How We Fix Them

• Series 375/377 fixed geometric units: seal failure in coastal exposure. The dual-seal insulating glass package on CGI’s Series 375 and 377 fixed geometric shapes uses a silicone primary and polysulfide secondary that degrades faster in Jupiter’s salt-laden easterlies than inland formulations. We see fogging between lites first on south- and east-facing gables in neighborhoods like Jupiter Inlet Colony and along Beach Road. Our fix: we source replacement IGUs with a warm-edge spacer upgrade and high-performance low-E coating matched to the original sightline, then document the glass package spec on your invoice for warranty tracking.
• Series 375 impact-rated arched tops: stress cracking at springline. The transition from rectangular jamb to radiused top in CGI’s arched impact units concentrates stress at the springline, particularly when the rough opening has settled or the header was field-modified during original construction. We diagnose this with a laser plumb reading of the jamb before quoting, then specify either a reinforced aluminum subframe or a split-jamb installation that isolates the geometric sash from structural movement. We have documented seven of these in Jupiter since 2019; six were resolved with subframe reinforcement, one required full replacement after the original installer omitted the structural clip.
• Series 377 oversized fixed units: glazing bead pop-out under positive wind load. CGI’s 377 series in sizes above 60″ x 96″ uses a snap-in vinyl glazing bead that can release under sustained positive pressure in Jupiter’s hurricane exposure, particularly on second-story great-room walls where internal pressure builds during a storm. We retrofit with a mechanically fastened aluminum glazing stop and structural silicone backup, a modification we document with before-and-after photos for your wind mitigation inspection file.
• Custom geometric sashes: hardware misalignment from thermal expansion differential. CGI’s custom geometric operating units, particularly trapezoids and pentagons with operable venting sections, use roto hardware sourced from European vendors whose aluminum alloy expansion coefficients differ slightly from CGI’s extrusion. In Jupiter’s summer heat cycles, this produces latch misalignment we measure in 1/32″ increments. We do not shim and hope; we replace with a matched alloy hardware set and verify engagement depth with a go/no-go gauge before final cleanup.
• Coastal anodized finishes: chalking on south exposures before warranty expiration. CGI’s standard coastal anodized finish, Class I for high-salinity environments, still chalks prematurely on geometric units with complex surface geometry that traps salt in radiused profiles. We see this most on custom radius-top units in Abacoa and Admirals Cove where the profile curvature creates micro-pooling. Our fix: we strip, re-anodize to Class II thickness, and apply a clear fluoropolymer topcoat, documenting the finish spec on your measured survey for future reference.

Our CGI Custom & Geometric Windows Process

1. 1
   Measured survey you keep. We arrive with a laser measure, digital level, and the documented photo record starting at your door. Sonia Raman or a verified crew member records rough opening width, height, square, and plumb at three points each, plus jamb depth and structural substrate condition. You receive this survey before we leave.
2. 2
   CGI series verification and failure mode diagnosis. We identify your existing CGI series from frame profile, glazing label, and hardware stamp, then cross-check against known failure patterns for that line in Jupiter’s exposure. If you are specifying new, we match the series to your wind-load zone, which in Jupiter runs from 140 mph to 170 mph depending on proximity to the Intracoastal.
3. 3
   Parts decision: OEM CGI or verified equivalent. For warranty-registered units under 10 years, we default to OEM CGI replacement parts with documentation for your claim file. For out-of-warranty or discontinued profiles, we source from verified aftermarket vendors whose alloy and finish specs we have tested in our own installations. We name the source on your written quote; no surprises on install day.
4. 4
   Fabrication oversight and delivery inspection. For custom geometric units, we verify CNC cutting dimensions against our measured survey before the glass is set, then inspect the finished sash for square, glaze, and hardware engagement at our receiving dock. We have rejected three CGI custom units in the past two years for springline deviation exceeding 1/8″ over 48″ - better to catch it before the truck rolls to Jupiter.
5. 5
   Installation, test, and documentation. We install to Florida Building Code TAS 201 and ASTM E330, test operable units for latch engagement and seal compression, and photograph the completed opening with the date stamp visible. Your photo record, written warranty, and final invoice - matching the original quote to the dollar - are delivered before we leave.
6. 6
   365-Day Done Right Promise activation. The Haven Standard’s Done Right Promise is stamped on your job record, not offered as a courtesy. If the sash drifts, the seal fogs, or the hardware binds in year one, we return and make it right. Evidence on every job means we have the photos to prove what was done.

What CGI Custom & Geometric Windows Costs in Jupiter

These are installed prices for typical CGI custom and geometric scenarios in Jupiter, based on jobs we have completed in the past 18 months. Your measured survey determines the exact figure; these ranges are for planning only.

We do not quote allowances. The price on your written estimate is the price on your invoice. Call (772) 362-5402 for your free measured survey and exact quote.

Why Jupiter Homeowners Call Sightline Windows & Doors Jupiter for CGI Work

We are independently owned and operated under the Haven Standard, not a franchise, and we have installed or serviced CGI products in Jupiter since 2014. Our crews are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3, Verified Crews. We answer the phone live, 24/7, because a fogged geometric sash on a Saturday is still a warranty issue on Monday.

Our multi-brand capability matters when CGI is not the right fit for a particular opening. We also specify, measure, and install PGT, CWS, ES Windows, and ECO Window Systems, selected by what the opening requires, not by what is in stock. If your Jupiter home needs a custom geometric unit that exceeds CGI’s current fabrication limits, we will say so and show you the alternative with the same written-price discipline.

Measure once, quote it straight, install it right - that’s the whole business. Sonia Raman has spent over a decade on Palm Beach County installations, including a stretch of impact-replacement work along Jupiter’s Indiantown Road corridor that taught her more about Florida wind-load specs than any classroom did. She still reads the rough opening before quoting it.
