How CGI Products Fail - and How We Fix Them

• Sentinel by CGI single hung sash drift. The balance shoe wears asymmetrically in Kendall’s salt-air environment, causing the sash to drop or tilt in its track. We see this most in units facing the Turnpike corridor where vibration compounds the wear. Our fix: replace the balance assembly with OEM-spec shoes and re-square the jamb liner, not the sash itself. We document the frame plumb before and after.
• Impact-rated horizontal roller hard roll and track gouging. The stainless steel tandem rollers on Estate Collection sliders seize when debris packs the bottom rail, then the sash drags aluminum into the vinyl track. Homeowners notice it first as resistance, then as a grinding sound during hurricane prep. We pull the sash, clean the rail cavity, replace with sealed-bearing rollers rated to the original DP, and photograph the track profile for your record.
• Sentinel double hung top-sash lock failure. The zinc die-cast tilt latch cracks after repeated cycling, especially where morning sun hits the upper sash and thermal expansion stresses the mechanism. We match the latch by die stamp, not by visual similarity; aftermarket latches that look right often fail to engage the keepers at full tilt, compromising the impact rating. We test three-point engagement before we leave.
• Fixed picture window seal breach in coastal exposure. The warm-edge spacer on older CGI fixed units corrodes at the edge where Kendall’s driving rains sit against the frame sill. Fog between panes is the late symptom; early signs are a chalky residue at the glass edge we catch during survey. We replace the insulated glass unit with a matched OEM build, re-bed with neutral-cure silicone, and record the spacer lot number.
• Estate Collection multi-point lock misalignment after settling. Kendall’s oolitic limestone substrate shifts seasonally, and the three-point lock on Estate swing doors drags at the deadbolt. Other techs file the keeper or shim the strike plate; we measure frame square, adjust the hinge barrel, and reset the multipoint rod travel to factory spec. Filing the keeper voids the impact certification. We don’t do it.

Our CGI Impact Windows & Doors Process

1. 1
   Measured survey you keep. Sonia Raman or a verified crew member arrives uniformed with license number visible, records every opening’s rough opening, reveal, and sightline dimension, and leaves you the handwritten sheet.
2. 2
   Diagnostics with photo evidence. We photograph the failure mode, the product label (series, DP rating, glass spec), and any adjacent damage. You get these images same-day.
3. 3
   Parts decision: OEM or qualified equivalent. For warranty-active CGI units, we use OEM parts to preserve coverage. For out-of-warranty work, we source equivalent components from our verified supply chain, never generic hardware that lacks Miami-Dade NOA documentation.
4. 4
   Dry-fit before sealant. Every sash, frame, or glass unit is set without sealant first. We check operation, lock engagement, and sightline alignment. Measure once, document it, then cut.
5. 5
   Final test and photo record. We cycle every operable unit ten times, verify lock function under load, and photograph the completed installation. The written invoice matches the survey; no additions, no change orders.
6. 6
   Haven Standard closeout. The 365-Day Done Right Promise is stamped on your paperwork, and the photo record uploads to your job file by evening.

If your CGI line is discontinued or the lead time doesn’t work, we specify from our other verified manufacturers: PGT, CWS, ES Windows, or ECO Window Systems, matched to the same performance tier, not whatever is in stock. The 365-Day Done Right Promise covers every job, and the photo record is standard, not an upsell.
