How CGI Products Fail - and How We Fix Them
- Sentinel by CGI single-hung sash drift. The balance shoe wears asymmetrically in Three Lakes homes where units are locked in the vented position through hurricane season. The sash creeps down an inch or two after closing. We replace with OEM balance assemblies rather than aftermarket clips, which don’t seat correctly in the Sentinel jamb profile. The fix holds because the replacement matches the original extrusion tolerance.
- CGI Estate Collection horizontal roller hard roll. The stainless steel tandem roller corrodes at the axle when screen tracks collect condensation from afternoon thunderstorms off the Everglades. Owners force the sash and deform the keeper. We pull the sash, clean the track to bare aluminum, install a sealed-bearing roller with marine-grade hardware, and adjust the strike so the lock engages without muscle.
- CGI Targa impact vinyl frame screw boss cracks. The reinforced PVC screw bosses for lock hardware fatigue after repeated cycling, especially on east-facing openings that take the full morning thermal expansion cycle. A stripped boss won’t hold a replacement lock. We epoxy-bond a threaded brass insert and reinstall the factory lock set, or sister the boss with a concealed angle bracket if the crack propagates to the glazing stop.
- CGI Sparta line glazing bead pop-out. The snap-in vinyl glazing bead on Sparta fixed and single-hung units shrinks faster than the frame in Three Lakes’s UV load, working loose at the miter corners first. Once air enters, the insulated glass unit fogs. We reset with OEM bead profile, not universal snap bead, because the Sparta glazing pocket depth is shallower than PGT’s equivalent. The IGU gets replaced if the desiccant is saturated.
- CGI sentinel impact door hinge zone settlement. On full-lite impact doors, the weight of laminated glass gradually stresses the hinge-side jamb, particularly where the header meets the hinge jamb on out-of-square openings common in 1980s Three Lakes construction. The door drags at the threshold. We shim the frame to plumb, replace with heavy-duty ball-bearing hinges sized for the actual door weight, and reseal the threshold pan so water runs to the exterior, not the subfloor.
Our CGI Impact Windows & Doors Process
- 1
Measured survey. Sonia Raman or a verified crew member records every rough opening dimension, frame squareness, and existing condition with photos you receive. The measurement document becomes your written quote; Haven Clause 1 means they cannot differ.
- 2
Diagnostics with series identification. We confirm the CGI series, manufacturing date from the etched mark in the glass corner, and whether the original installation used CGI’s specified fasteners or generic substitutes that void warranty coverage.
- 3
Parts decision. OEM CGI hardware when available and warranty-relevant; quality aftermarket when the OEM part is obsolete or when the aftermarket spec exceeds original (we’ve used heavy-duty stainless rollers on Estate Collection units where CGI’s original axle diameter was undersized for the sash weight).
- 4
Repair or replacement execution. Work proceeds per the written scope, with no additional items added without a second written approval. We don’t “find” problems after the price is set.
- 5
Operational test and photo record. Every moving sash is cycled twenty times, every lock is torque-tested, and every completed job is photographed for your records and ours. Evidence on every job, Haven Clause 4.
- 6
365-Day Done Right Promise activation. The warranty document is generated from the same file as your quote and your photos. If it’s not done right, we make it right. That’s written into the Haven Standard, not offered as a courtesy.

Why Three Lakes Homeowners Call Sightline Windows & Doors Three Lakes for CGI Work
We’ve worked on homes backing up to the Killian Corridor where the afternoon sun loads are no joke and the wrong glazing choice shows up on your FPL bill every month. Sonia Raman specifies impact-rated units that meet Miami-Dade Notice of Acceptance requirements without upselling product a house doesn’t need. Our crews are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. If your CGI line is discontinued or lead times stretch, we can cross-specify from PGT, CWS, ES Windows, or ECO Window Systems from our measured survey, not from a catalog guess. Measure once, quote it straight, install it right - nothing else belongs on the invoice.
FAQs
No. As an independent CGI service provider, we perform warranty-safe work using OEM or equivalent-spec parts. CGI’s limited lifetime warranty covers manufacturing defects regardless of who services the unit, provided the work doesn’t damage the frame or glass. We document our methods with photos so any future claim has evidence. Call (786) 808-5792 if you need warranty guidance on a specific unit.
Common Sentinel and Estate Collection hardware ships within 3-5 business days. Discontinued Sparta line parts may take 10-14 days or require us to machine a compatible substitute we warranty ourselves. We don’t start work until parts are in hand - no return visits charged as “trip fees.” Call (786) 808-5792 to check availability for your series.
Most CGI units are repairable if the frame is structurally sound and the glass isn’t compromised. We replace when the frame is cracked at the weld, the IGU has failed beyond economical repair, or the series is obsolete and parts are unavailable. Our written estimate separates repair and replacement options with installed prices for each. Call (786) 808-5792 for an assessment.
No. Haven Clause 1 and Haven Clause 5: the written price before work starts is the final price. The only exception is concealed structural damage we couldn’t reasonably detect during survey - rot in the rough opening, for example - and even then, we stop, photograph, and write a second scope for your approval before continuing. Call (786) 808-5792 to schedule your free estimate.
Every CGI impact unit has an etched mark in the corner of the glass showing the manufacturer, product standard, and Miami-Dade Notice of Acceptance number. We photograph this mark during survey and again after installation. We also provide the product label from the frame for your records. If you’re uncertain about existing units, call (786) 808-5792 and we’ll verify during your free estimate.
