How CGI Products Fail - and How We Fix Them

• Sentinel by CGI horizontal rollers with seized tandem rollers. The stainless tandem roller assembly in this series collects salt and calcium from Boca Raton’s coastal air, particularly in oceanfront condos along A1A. The sash drags, the lock misaligns, and homeowners force it until the keeper bends. We replace with OEM tandem rollers or a marine-grade equivalent, realign the sash to the original sightline, and lubricate with a synthetic grease that won’t wash out in the first summer storm.
• Sparta single-hung balance shoe fracture. The nylon balance shoe in older Sparta units fatigues after repeated heat cycling - Boca Raton’s attic-frame temperatures regularly top 140°F, and the thermal stress concentrates at the shoe’s pivot pin hole. The sash drops or tilts unexpectedly. We stock the OEM shoe and the alternate pulley-style retrofit kit; which we use depends on whether the jamb liner is still square, which we check with a framing square before quoting.
• Impact-rated fixed picture windows with seal failure (fogging between lites). CGI’s impact glass packages use a polyvinyl butyral (PVB) interlayer that outlasts the insulated glass unit (IGU) edge seal in many installations. The fogging is cosmetic at first, but the failed seal breaches the argon fill and degrades the U-factor. We measure the IGU precisely, order a replacement from the original fabricator when possible, and document the SHGC and visible transmittance so the new unit matches the original performance label.
• WinGuard vinyl impact windows with warped sash frames. The multi-chambered vinyl profile in WinGuard can thermally distort when dark exterior colors absorb afternoon sun on west-facing elevations - common in Boca Raton’s Royal Palm Yacht & Country Club and Boca West properties. The warp prevents proper lock engagement and compresses the weatherstrip. We assess whether the sash is field-replaceable or if the full frame has racked; if the latter, we quote a complete replacement with a lighter exterior color or a heat-reflective lamination.
• Impact door hinge-side frame cracking at the fastener cluster. CGI entry doors in coastal Boca Raton see repeated wind-load cycling; the concentrated stress at the upper hinge fasteners can propagate a crack in the reinforced frame. This is not a door replacement - it’s a frame repair with a backer plate, structural epoxy, and re-fastening into virgin substrate. We pull the permit when required by Boca Raton’s building department and document the repair with photos for your record and any future insurance claim.

Our CGI Impact Windows & Doors Process

1. 1
   Measured survey. We record every rough opening dimension, squareness, and plumb with a laser and a story pole - the same tools Sonia Raman learned at Los Angeles Trade-Technical College. You keep the survey sheet.
2. 2
   Diagnosis with parts identification. We identify the CGI series, the vintage, and whether the part is still manufactured. If OEM is discontinued, we specify the quality aftermarket equivalent and explain the trade-off before you decide.
3. 3
   Written quote. The price is fixed to the survey. No change orders. No “we found more once we opened it up.” Measure it twice, write it down, then we can talk price.
4. 4
   Repair or replacement. Our background-checked, uniformed technicians arrive with license numbers visible. They work to the Haven Standard: verified crews, evidence on every job, no surprises.
5. 5
   Testing and documentation. Every impact unit is operated through full travel, locks are cycled, and we verify the weatherstrip compression. You receive a photo record of the completed work and the 365-Day Done Right Promise in writing.
6. 6
   Cleanup and closeout. We haul debris, protect your floors during the job, and leave the work area as we found it. The invoice matches the quote - Haven Clause 1 again.
