CGI Window Replacement: The Boynton Beach Owner’s Guide

CGI window replacement in Boynton Beach typically runs $340-$780 per opening for standard vinyl impact units, with most jobs scheduled within 48 hours and same-day availability for in-stock sizes. We carry CGI-compatible sashes, balances, and hardware on our trucks, and we verify the exact series code before ordering anything. Most homeowners in Boynton Beach realize they need a replacement when the sash won’t stay open, the locking rail separates from the frame, or they feel air movement around a closed window after a storm season.

Which CGI Models This Applies To

CGI manufactures several distinct product families, and the replacement approach differs by series. The Sentinel line uses a heavier extrusion with a 3-1/4″ frame depth and integrated reinforcement, while the Estate series runs a 2-7/8″ profile with a different balance cartridge. We see the most replacement calls in Boynton Beach for the Sentinel 200 and 400 series, the Estate 7000 line, and the commercial-grade Targa fixed and projected windows installed during the 2016-2019 building cycle.

To identify your exact model, check the etched mark in the glass corner or the sticker on the frame head. It will read something like “CGI-SEN-200” or “EST-7120-SH.” The critical compatibility gotcha: Estate 7000 balances from units manufactured before 2018 use a 5/8″ pivot bar, while post-2018 production switched to 3/4″. Order the wrong one and the sash tilts out of plane within a month. We stock both pivot bar sizes and verify with a caliper before any part leaves our Boynton Beach warehouse.

On OEM versus aftermarket: CGI’s own parts program carries full sashes and hardware, but lead times run 3-4 weeks. For balances, rollers, and keepers, we use an ASTM-tested aftermarket equivalent that matches the original spec and carries the same 10-year warranty. We note the source on every written quote so you know what you’re getting.

Signs Your CGI Window Replacement Is Failing

• Sash drops or won’t stay open. The coil balance has lost tension, usually from corrosion at the pivot shoe. In Boynton Beach, salt air accelerates this; we’ve pulled balances from Intracoastal-facing homes that were rust-solid after six years.
• Visible gap between sash and frame when locked. The interlock rail has warped or the weatherstrip has compressed past recovery. On CGI’s vinyl lines, the interlock is a co-extruded bulb seal that hardens in direct sun; replacement requires the full sash, not just a gasket swap.
• Condensation between glass panes. The insulated glass unit (IGU) seal has failed. For CGI impact-rated windows, the IGU is laminated to the inner lite; replacement means ordering the exact glass makeup, including the PVB interlayer thickness, or the impact certification is void.
• Locking mechanism grinds or won’t engage. The multipoint lock cam has worn or the keepers have shifted. On Sentinel 400 series, the keeper screws into a vinyl boss that strips easily if over-torqued; we helicoil and re-anchor, or replace the jamb liner if the boss is cracked.
• Frame corner separates or bows. The fusion-welded joint has stress-cracked, often from thermal expansion against a stucco return. This is structural; a sash replacement won’t fix it, and we flag it during our measured survey before quoting any parts.

Replacement Cost & What’s Included

Every quote we write in Boynton Beach includes the measured survey you keep, the part specification by manufacturer and series, labor to remove and install, debris disposal, and the documented photo record. Our 365-Day Done Right Promise applies to all replacement work. The price on the page is the price on the invoice; Haven Clause 1 means the measurement and the quote are the same document.

DIY or Call Us?

There’s a safe middle ground for most CGI window issues. A homeowner can verify the model code, check for visible frame cracks, and photograph the failure for reference. What we don’t recommend: removing a sash with a failed balance (the sash is heavier than it looks and the tilt latches can snap), cutting sealant to free a fixed unit (you’ll compromise the water management plane), or ordering glass without confirming the DP rating and Miami-Dade notice of acceptance number.

We’ve replaced enough windows in Boynton Beach to know where DIY ends. Sonia Raman keeps a list of every unit she’s had to pull because a previous owner used the wrong sealant or skipped the sill pan. It’s longer than she’d like, and it’s why she checks her own crew’s caulk joints before any truck leaves a site. For a written price and a verified part match, call (561) 421-3844.
