How CGI Products Fail - and How We Fix Them

• Sentinel by CGI laminated glass delamination at the edge seal. In Opa-locka’s salt-air corridor, the interlayer can separate from the glass lite near the spacer after seven to ten years, creating a foggy perimeter that reads as moisture intrusion but is actually adhesive breakdown. We remove the sash, verify whether the delamination has compromised the impact rating per Florida Building Code TAS 201/202, and replace with OEM laminated glass or an equivalent impact-rated assembly that matches the original design pressure.
• Sparta single-hung balance shoe fracture in the jamb liner. The nylon balance shoes in older Sparta units fatigue under repeated cycling, especially in homes near Opa-locka Executive Airport where vibration is a constant environmental load. We replace with CGI-specified balance shoes rather than universal aftermarket parts, because the jamb liner groove geometry is proprietary and a misfit will bind the sash within two seasons.
• WinGuard horizontal roller corrosion in the sill track. The stainless steel rollers and aluminum track develop galvanic corrosion when salt accumulates in the sill during Opa-locka’s wet season, causing the sash to drag or jump the track. We pull the sash, media-blast the track to bare aluminum, apply a zinc-rich primer compatible with CGI’s finish warranty, and install OEM rollers with the correct axle diameter - not the 3/4-inch generic that binds in the WinGuard housing.
• Architectural Collection corner key separation in multi-lite assemblies. The mechanical corner keys in larger Architectural Collection fixed units can loosen when the thermal expansion differential between the exterior and interior aluminum tubes exceeds the design tolerance - something we see more often in Opa-locka’s unshaded western exposures than in shaded northern lots. We disassemble the frame, re-crimp with CGI’s specified corner key profile, and re-glaze with fresh setting blocks to restore the original shear strength.
• Impact door hinge mortise crush in Estate Entrances fiberglass units. The dense fiberglass door slab can compress at the hinge mortise if the original installation used standard wood screws rather than CGI’s specified machine screws into the composite reinforcement block. We re-machine the mortise, install helical inserts where the substrate has crushed, and hang the door on the correct fastener schedule so the weight distribution returns to factory specification.

Our CGI Impact Windows & Doors Process

1. 1
   Measured survey. We arrive with a laser measure, a moisture meter, and a camera. Sonia Raman or a verified crew member records every rough-opening dimension, notes the existing frame’s attachment method to the CMU or wood buck, and checks for water intrusion at the sill. You keep this survey.
2. 2
   Written scope and price. We specify the exact CGI series, glass make-up, and hardware finish. The quote is the same document as the survey - Haven Clause 1. No verbal add-ons, no “we’ll see when we get into it.”
3. 3
   Parts decision. For repairs, we source OEM CGI parts when available and when warranty compliance matters. For older discontinued series, we specify quality aftermarket equivalents with documented DP ratings and finish-match guarantees - never a guess.
4. 4
   Installation or repair. Background-checked, uniformed technicians, license number provided before arrival. We protect floors, contain dust, and photograph each phase: rough opening, flashing detail, fastener pattern, and final shim placement.
5. 5
   Testing and documentation. Every operable unit is cycled twenty times. Impact-rated assemblies are checked for proper engagement of the interlock. You receive the photo record and the 365-Day Done Right Promise in writing.
6. 6
   Cleanup and close. We haul debris, vacuum sills, and leave the written warranty and maintenance schedule on the kitchen counter. The invoice matches the quote to the dollar.

Why Opa-locka Homeowners Call Sightline Windows & Doors Opa-locka for CGI Work

We have installed and serviced CGI products in Opa-locka since 2012, including a stretch of commercial and residential work near Ali Baba Avenue that remains some of the most technically demanding framing our crew has encountered - tight rough openings in CMU construction with inconsistent mortar joints that taught us to measure every opening twice and photograph the buck condition before ordering glass. Our 365-Day Done Right Promise is written into the Haven Standard, not offered as a courtesy. Every technician is background-checked, uniformed, and identified by license number before arrival. Because we carry eight manufacturer lines - PGT, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux alongside CGI - we can specify by what the opening requires, not by what is in stock. Live phone coverage is available 24/7. Measure it right the first time, document everything, and let the finished opening speak for itself.
