This page is for Clewiston homeowners who already own CGI products and need honest answers about what’s failing, what it’ll cost to fix, and whether the repair will hold through another hurricane season. We’ve worked on CGI frames in homes from the historic district near Sugarland Park to newer builds off East Ventura Avenue, and the humidity around Lake Okeechobee creates seal failures you won’t see in drier Florida markets.

How CGI Products Fail - and How We Fix Them

• Sentinel by CGI single-hung sashes drop or stick. The balance shoe in the Series 210 and 230 tilt-wash units wears flat where it rides the jamb liner, especially in Clewiston’s salt-air environment. We replace with OEM balance assemblies rather than lubricating and hoping; the new shoe restores proper sash tension so the window stays where you put it.
• Impact-rated horizontal rollers develop track pitting. The Estate Collection and Targa by CGI sliding windows collect grit from our limestone-rich soil in the track, accelerating wear on the stainless steel rollers. We pull the sash, clean the track to bare metal, and install sealed-bearing rollers that don’t bind when debris returns.
• Sentinel double-hung upper sashes lose their weatherstrip seal. The bulb gasket compresses permanently after five to seven years of thermal cycling in Clewiston’s 90-plus-degree summers. We source the exact Durometer bulb from CGI’s parts catalog - not universal strip - so the sash compresses evenly and the impact rating stays intact.
• Fixed picture windows weep at the sill. On the Estate Collection and Aria lines, the weep hole baffle clogs with pollen and cane-field dust, trapping water against the sill leg. We clear the baffle, verify the sill pan slopes to drain, and reseal with neutral-cure silicone that won’t outgas and degrade the glazing tape.
• Targa casement operators strip gears. The Truth Hardware operator in older Targa units fails at the worm gear when homeowners force a warped sash closed. We replace the entire operator mechanism with the current Truth Encore specification and realign the sash to the frame so the new gears don’t inherit the same load.

Our CGI Impact Windows & Doors Process

1. 1
   Measured survey you keep. We record every rough opening dimension, frame squareness reading, and sightline measurement on a document you sign and retain. Sonia Raman checks critical openings personally - she’ll pull a frame twice before letting a bad measurement get buried behind trim.
2. 2
   Diagnosis with photo evidence. We photograph the failure mode, the part number, and the surrounding frame condition. You see what we see before any work is approved.
3. 3
   Parts decision: OEM or verified equivalent. For warranty-active CGI products, we use OEM parts to preserve coverage. For out-of-warranty units, we specify quality aftermarket alternatives when they meet or exceed the original spec - and we document the substitution in writing.
4. 4
   Repair or replacement with verified crews. Our technicians arrive uniformed with license numbers visible, install per CGI’s published tolerances, and test every operable unit for function and seal.
5. 5
   Photo record and written sign-off. We leave you with dated photos of the completed work, the final invoice matching your quote, and the 365-Day Done Right Promise stamped under Haven Clause 5: No Surprises.
6. 6
   Follow-up at 90 days. We call to confirm the repair held through its first full season - not because we’re worried, but because Haven Clause 4 (Evidence on Every Job) means we verify outcomes, not just outputs.

Why Clewiston Homeowners Call Sightline Windows & Doors Clewiston for CGI Work

We’ve installed and serviced 18,000-plus openings since 2012, every one with a written price before work started and a documented photo record when finished. Our crews know CGI’s product evolution - which Estate Collection sashes used the old-style tilt latch, which Targa operators cross-reference to current Truth Hardware - because we’ve repaired them in Clewiston homes, not just read the catalog.

If your CGI line is discontinued or lead times stretch, we specify from our other verified manufacturers: PGT, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. The opening’s performance requirements drive the specification, not our warehouse inventory. Haven Clause 3 means the technician at your door is background-checked, uniformed, and identified by license number before arrival - the person on the record is the person on your porch.

And if something’s not right, the 365-Day Done Right Promise isn’t a courtesy call. It’s written into the Haven Standard, same as the price guarantee and the photo record. Measure it right the first time. Everything after that is just paperwork.
