CGI Custom & Geometric Windows in Belle Glade: What to Know First

We install and service CGI custom and geometric windows in Belle Glade as an independent CGI service provider, with most measured surveys scheduled within a few business days and written quotes delivered before any work begins. Typical custom CGI installations run $2,800-$7,500 depending on shape complexity, impact rating, and whether the opening needs reframing. This page is for homeowners who already own CGI products or are specifying them for arched, curved, or oversized openings and want the price in writing before a tool is lifted. Call (561) 286-4734 to schedule your measured survey.

How CGI Products Fail - and How We Fix Them

• CGI Estate Series arched tops: seal drift in the radius. The curved aluminum extrusion in Estate geometric units expands differently than the straight leg below, and after five to seven Florida summers the glazing seal can walk. We see this near McDonald Park on homes where the original installer used standard backbedding instead of the radius-specific silicone profile. We remove the sash, clean the old sealant with a solvent wipe, and re-glaze with Dow 795 or GE SCS2000 matched to the expansion coefficient.
• CGI Sentinel impact-rated geometric windows: corner key stress cracking. Sentinel’s reinforced corners carry the impact load, but in trapezoid and pentagon shapes the miter forces concentrate at the narrow end. The symptom is a hairline crack propagating from the interior corner toward the glass stop, often misdiagnosed as impact damage. We replace with OEM corner keys rather than field-fabricated alternatives, because CGI’s heat-treated zinc alloy maintains the tested impact rating; aftermarket keys void the Miami-Dade NOA.
• CGI Targa oversized custom units: sash drop on the hinge side. Targa’s heavier laminated glass in large geometric configurations can overcome the standard hinge set, particularly on direct-set octagon windows above 48 inches. The sash creeps closed or binds at the lock. We upgrade to the heavy-duty stainless hinge pack and reset the frame plumb with composite shims, not cedar, which crushes under sustained load.
• CGI Sparta fixed geometric windows: weep channel blockage from pollen and sugar sand. Belle Glade’s muck soil generates fine particulate that migrates into the sill track; combine that with royal poinciana pollen in May and the weep slots clog. Water pools in the sill, stains the drywall, and the homeowner thinks the window leaks. We clear with regulated compressed air, install insect-resistant weep covers, and document the frame drainage test with a photo.
• CGI custom anodized finishes: chalking on south and west exposures. Anodized aluminum in Belle Glade’s high-UV environment can develop surface oxidation that looks like fading but is actually aluminum hydroxide buildup. It happens faster on geometric windows because the angled surfaces catch more direct sun. We do not recommend repainting anodized frames; instead, we source replacement sashes with Kynar 500 fluoropolymer finish, which carries a 20-year chalk rating and matches CGI’s current color palette.

Our CGI Custom & Geometric Windows Process

1. 1
   Measured survey. Sonia Raman or a verified crew member arrives with a laser measure and level, records the opening in six points (not four), and notes wall squareness, header condition, and interior trim constraints. You keep a copy of this document.
2. 2
   Diagnostics and parts decision. We identify the CGI series, manufacturing date (stamped on the glass spacer or frame label), and whether the issue is component failure or installation error. OEM parts are specified first; we only substitute quality aftermarket when the OEM part is discontinued and the substitution is documented as equivalent.
3. 3
   Written scope and price. The measured survey becomes the quote. No line item is added after you approve. Haven Clause 1: have it in writing.
4. 4
   Installation or repair. Background-checked, uniformed technicians arrive with license numbers visible. For geometric replacements, we verify the new unit against the template before removing the old frame.
5. 5
   Testing and documentation. Every job gets a photo record: before, during, and after, including the operational test and the final sightline check. The 365-Day Done Right Promise is stamped on your invoice.
6. 6
   Cleanup and closeout. We leave the work area as found, haul away the old unit, and email your documented photo record within 24 hours.
