Our quotes start with the measured survey you keep, and that document and the final invoice are the same paper - Haven Clause 1, no exceptions.

How CGI Products Fail - and How We Fix Them

• Sentinel by CGI single hung sashes dropping out of alignment. We see this regularly in Boynton Beach homes built between 2015 and 2019, especially on east-facing walls where thermal expansion cycles are aggressive. The balance shoe wears asymmetrically, and the sash tilts until the tilt latch cracks. We replace the balance assembly with OEM-spec components and check the jamb liner for deformation - if it’s out of square by more than 1/16 inch, we shim before reinstalling so the new balance doesn’t inherit the same load pattern.
• Impact-rated horizontal rollers with corroded stainless steel rollers. CGI’s Estate Collection rollers use 440C stainless that holds up well inland but degrades faster within a mile of salt air, which in Boynton Beach means anywhere near the Intracoastal or east of Federal Highway. The roller doesn’t seize immediately; it develops flat spots that score the sill track. We replace with marine-grade 316L rollers where the exposure warrants it, and we document the sill track condition in the photo record so there’s no dispute later about pre-existing damage.
• Sentinel double hung top sash lock failure after impact test pressure cycling. The lock mechanism itself is robust, but the keeper screw holes in the vinyl jamb can oval out over years of pressure flex. Homeowners notice the lock lever moves but doesn’t engage. We don’t just replace the lock; we backfill the stripped holes with structural epoxy and re-tap, or relocate the keeper if the jamb integrity is compromised. This preserves the impact rating - a critical point, since relocating hardware on an impact-rated unit requires recalculation of the design pressure.
• CGI fixed picture window seal failure presenting as interior condensation between panes. The warm-edge spacer in pre-2018 units can lose adhesion in the Florida heat, and Boynton Beach’s afternoon sun loads on west walls accelerate this. The glass is impact-rated and expensive to replace as a full unit. We first verify whether the seal breach is localized - sometimes repairable with a perimeter vacuum-and-fill - and we quote both paths. If full IGU replacement is necessary, we source through CGI’s distribution channel with the original DP rating stamped on the spacer, not a generic aftermarket equivalent that voids the product’s Miami-Dade notice of acceptance.
• Estate Collection sliding door tandem roller carriage collapse under weight. The tandem roller design carries heavy impact-laminated glass well when new, but the polymer axle bushings degrade. In Boynton Beach, we see this most often on south-facing patio doors where UV exposure is maximum. The door becomes hard to roll, so homeowners muscle it, which bends the aluminum track. We replace the full carriage with OEM tandem rollers, realign the track with a precision level (not eyeball), and check the header deflection - if the header has sagged, the new rollers will fail the same way.

Our CGI Impact Windows & Doors Process

1. 1
   Measured survey and written scope. Sonia Raman or a verified crew member arrives with a license number you can check, measures every opening with a laser and tape (we cross-check both), and records frame squareness, sill condition, and existing fastener patterns. You keep the survey; it becomes the quote.
2. 2
   Parts verification. We identify the CGI series, manufacturing date range, and DP rating from the etched mark on the glass or the frame label. For discontinued components, we source OEM-equivalent parts that maintain the impact rating - we do not substitute generic hardware on impact-rated units without documenting the engineering equivalency.
3. 3
   Written price before work starts. The quote is line-itemed: labor, materials, disposal, permit if required. In Boynton Beach, most CGI impact window replacements do not require a permit if the opening dimensions are unchanged, but we verify with Palm Beach County and include the permit cost in writing if it’s needed. No change orders unless you add scope.
4. 4
   Installation by verified crew. Background-checked, uniformed technicians arrive on schedule - Haven Clause 2. For CGI units, we use the manufacturer’s specified fastener pattern and sealant; Sonia checks caulk joints personally before any truck leaves, based on a list she keeps of windows she’s had to replace due to wrong sealant.
5. 5
   Testing and documentation. Every operable unit is cycled twenty times, locks are engagement-tested, and we verify the sash or panel meets the original DP rating’s deflection limits. The photo record - frame close-ups, fastener heads, sealant beads, operational test - is uploaded to your job file.
6. 6
   365-Day Done Right Promise. If anything fails due to our work or our parts selection, we return and make it right. The promise is written into the Haven Standard, not offered as a courtesy.
