How CGI Products Fail - and How We Fix Them

• Sentinel by CGI single hung sash drift. The balance shoe in the jamb liner wears asymmetrically in coastal humidity, causing the sash to drop or tilt when opened. We see this regularly in West Palm Beach homes built between 2015 and 2019. Our fix: replace the balance assembly with the correct OEM shoe and spring set for the sash weight, then verify the tilt latch engagement before we leave. Using a generic balance shoe here will fail again within two seasons.
• Impact-rated horizontal roller (Series 375) hard to slide or lock. The tandem roller carriage corrodes where the stainless axle meets the aluminum housing, especially on east-facing openings that catch salt spray off the Intracoastal. The sash drags, and the mortise lock misaligns. We replace the full roller carriage, not just the wheel, and reset the lock keep to the new sash position.
• Sentinel double hung top sash seal failure. The bulb seal compresses permanently after years of heat cycling, losing the design pressure rating at the meeting rail. This is not visible until we run the smoke pencil or measure with a manometer. We install the correct durometer replacement seal and verify DP rating restoration with the sash closed and locked.
• Series 375 fixed picture window weep blockage. The weep flap valve hardens and traps water in the sill track, which then enters the wall cavity during a driving rain from the southeast, common in West Palm Beach summer storms. We clear the track, replace the flap with a silicone alternative that stays flexible above 90 degrees, and document the sill slope with a photo for your record.
• Impact door (Sentinel entry system) hinge screw strip-out. The MDF composite jamb does not hold a wood screw under repeated wind loading; the hinge pulls, and the door drops. We install helical thread inserts with the correct length machine screw, restoring plumb and latch engagement without replacing the jamb. This is a warranty-safe repair if done with the right insert depth and thread pitch.

Our CGI Impact Windows & Doors Process

1. 1
   Measured survey. We record every opening with a laser measure and document frame squareness, rough opening condition, and existing fastening pattern. You keep this document.
2. 2
   Diagnostic with parts identification. We determine whether the failure is in the glazing, hardware, or frame, and identify whether OEM CGI parts are available or a quality aftermarket equivalent meets the specification. For discontinued Series 375 hardware, we maintain a parts cross-reference built from fifteen years of field data.
3. 3
   Written scope and price. The quote lists every part by description and every labor hour by task. Haven Clause 1: the measured survey and the quote are the same document.
4. 4
   Repair or replacement with documented steps. Our background-checked, uniformed technicians perform the work; license numbers are provided before arrival. We photograph each stage for your record.
5. 5
   Operational test and pressure verification. Every moving sash is cycled twenty times. Every lock is torque-tested. Fixed units are checked for seal integrity.
6. 6
   Cleanup and final documentation. You receive the photo record, the completed scope document, and the 365-Day Done Right Promise stamped under the Haven Standard.

What CGI Impact Windows & Doors Costs in West Palm Beach

Price moves with sash size, impact rating required, and whether the existing frame can be preserved. Coastal exposure adds material cost for marine-grade hardware. We do not quote over the phone without a measured survey. Call (561) 354-3861 for your free estimate.

Why West Palm Beach Homeowners Call Sightline Windows & Doors West Palm Beach for CGI Work

We have installed and serviced more than 18,000 openings since 2012, and a significant share of those have been CGI products in the West Palm Beach market. Sonia Raman, who leads our operation, learned frame systems and glazing tolerances at Los Angeles Trade-Technical College before spending fifteen years measuring and installing in South Florida. Her crews work regularly along Flagler Drive and throughout the surrounding neighborhoods.

The 365-Day Done Right Promise is written into the Haven Standard, not offered as a courtesy. Our technicians are background-checked, uniformed, and identified by license number before arrival. If CGI lead times are prohibitive, we can specify a functionally equivalent product from PGT, CWS, ES Windows, or ECO Window Systems, drawn from our eight verified manufacturer lines, because we stock no inventory and specify by what the opening requires.
