How CGI Products Fail - and How We Fix Them
- Sentinel by CGI single-hung impact windows: sash drift and tilt-latch wear. The tilt-latch mechanism on older Sentinel units in Tamiami homes, especially those facing afternoon sun along Tamiami Trail, develops play after repeated heat cycles. The sash drifts down an inch or two when unlocked, which owners often blame on the balance system. We measure the frame squareness first - South Florida slab settlement is real - then replace the tilt-latch assembly with OEM parts or machine-grade equivalents that match the original pin geometry. If the balance is actually fatigued, we replace both sides so the sash tension stays matched.
- CGI Estate Collection horizontal rollers: track galling and roller collapse. The stainless track on Estate Collection sliders can develop galling when grit from Tamiami’s limestone-rich soil gets trapped under the roller wheels. Owners feel resistance before they see damage. We pull the sash, inspect the track for metal transfer, and replace the roller trucks with OEM-spec Delrin wheels rated for the sash weight. In cases where the track itself is scored, we sleeve it or replace the track section rather than selling you a full frame - Haven Clause 5 means no surprises, including unnecessary full replacements.
- CGI impact door multi-point locks: misalignment after seasonal swelling. Tamiami’s wet season pushes humidity through screened entries, and the laminated jamb on CGI impact doors moves more than owners expect. The multi-point bolts no longer seat cleanly in the keepers. We don’t just adjust the strike plate; we check the hinge-side plumb with a long level, shim the frame if the rough opening has settled, and reset the lock mechanism to factory clearances. The fix lasts because we address the frame, not just the symptom.
- CGI sentinel vinyl impact windows: glazing bead hardening and seal breach. The glazing bead on first-generation Sentinel vinyl units gets brittle after eight to ten years of UV exposure - accelerated in Tamiami by the reflective heat off concrete pool decks and light-colored stucco. Once the bead cracks, the insulated glass unit loses its seal integrity. We remove the sash, document the IGU dimensions and spacer type, and order a replacement unit that matches the original Miami-Dade NOA submission. The new glazing bead we install is UV-stabilized to the current CGI spec, not whatever a supplier has in the warehouse.
- CGI impact window and door screens: spline failure and frame twist. The extruded screen frames on CGI products hold their shape well, but the spline groove can deform if a previous installer used a flat-head screwdriver instead of a spline roller. We see this on rental properties near the Miccosukee Resort corridor where maintenance turnover is high. We square the frame on our bench, replace the spline with the correct diameter for the mesh weight, and tension the screen so it doesn’t drum or sag. It’s a small job, but we document it in the photo record same as a full window replacement - Haven Clause 4, Evidence on every job.
Our CGI Impact Windows & Doors Process
- 1
Measured survey you keep. Sonia Raman or a verified crew member arrives with a license number you can check, measures every opening with a laser and tape, and notes frame condition, existing fasteners, and Miami-Dade NOA label locations. You keep the survey sheet.
- 2
Written scope and price. We specify the exact CGI series, the part numbers or compatible alternatives, and the labor line items. The quote and the survey are the same document - Haven Clause 1, Have it in writing. No verbal add-ons later.
- 3
Parts decision: OEM or verified equivalent. For current CGI lines, we order factory-direct when lead times are acceptable. For discontinued series or when the owner needs faster turnaround, we source parts that match the original performance spec and document the substitution in writing. We don’t guess on impact-rated components.
- 4
Installation with photo record. The crew installs to the measured survey, not to “close enough.” We photograph the rough opening before, the fastening pattern during, and the finished operation after. You get the photo record within 24 hours.
- 5
Operational test and sign-off. Every sash is cycled, every lock is tested with pressure, every weep hole is cleared. We check the sightline - the visible glass edge when the window is closed - for consistent reveal, because that’s what you look at every day.
- 6
Cleanup and 365-Day Done Right Promise. We haul debris, protect your floors during the job, and leave the written warranty with the Haven Standard stamp. If it’s not done right, we make it right - not as a favor, but as the documented terms of the engagement.

Why Tamiami Homeowners Call Sightline Windows & Doors Tamiami for CGI Work
We’ve been measuring, ordering, and installing windows and doors across South Florida since 2012, and Tamiami has been a consistent part of our territory - including full impact-window retrofits near the Miccosukee Resort corridor and replacement work in the neighborhoods abutting Tamiami Trail. Sonia Raman reads a rough opening correctly the first time and orders product that matches Miami-Dade NOA requirements before a permit question ever comes up. That’s not a claim; it’s how we avoid the change orders that plague this trade.
Our multi-brand capability matters when CGI lead times stretch or when a discontinued series needs a compatible alternative. We also specify and install PGT, CWS, ES Windows, and ECO Window Systems - specified by what the opening requires, not by what is in stock. Every technician is background-checked, uniformed, and identified by license number before arrival. Calls are answered by a live person, 24/7. And the 365-Day Done Right Promise is stamped on every job, not offered as a courtesy.
Measure it right, order it right, install it once.
FAQs
No. As an independent CGI service provider, we perform work that does not alter the original product’s NOA certification or factory glass warranty. We use OEM or equivalent parts, document substitutions in writing, and never modify the frame or glazing package in ways that would invalidate Miami-Dade approval. If your CGI windows are still under the original manufacturer’s warranty, we can identify which components are factory-covered versus wear items before we start. Call (786) 321-9118 to review your situation.
Current CGI series typically ship within five to ten business days to our South Florida warehouse. Discontinued lines, including early Sentinel vinyl configurations, may require us to machine-match or source verified equivalents, which can add three to five days. We tell you the lead time in writing before you commit, and we don’t collect a deposit until you approve the full scope. Call (786) 321-9118 to check availability for your specific series.
Repair makes sense when the frame is square, the NOA label is intact, and the failure is isolated to a sash, balance, or hardware component. Full replacement is the better value when the frame has settled out of plumb, the glazing package has failed, or the series is discontinued and parts are no longer supportable. We make this recommendation during the measured survey and explain it with frame readings, not sales pressure. Call (786) 321-9118 for a free assessment.
No. Haven Clause 1 means the written quote and the measured survey are the same document. The only circumstance where the price changes is if we discover concealed damage that was not visible during the initial survey - rot in the rough opening, for example, or a prior install that violated code. In that case, we stop work, photograph the condition, and present a written amendment before proceeding. You approve it or we restore the opening and leave. Call (786) 321-9118 to schedule your survey.
Yes, when Miami-Dade requires them for High Velocity Hurricane Zone replacements or alterations. We pull the permit, schedule the inspection, and pass it. The permit cost is listed separately in your written quote, not hidden in labor. For like-for-like sash replacements in some circumstances, permitting may not be required; we tell you which category your job falls into before you sign. Call (786) 321-9118 to confirm for your specific opening.
