CGI Window Replacement: The West Palm Beach Owner’s Guide
CGI window replacement in West Palm Beach typically runs $380 to $1,200 per opening installed, depending on series, size, and whether the frame is being replaced or just the sash and hardware. We stock common CGI parts on our trucks and can usually complete the replacement within one visit once the measured survey confirms the spec. Most West Palm Beach homeowners discover the problem when a window won’t stay open, won’t lock, or shows visible frame separation after a storm season.
Which CGI Models This Applies To
CGI windows carry a white label inside the frame rail with the series code, date of manufacture, and NFRC ratings. The most common units we replace in West Palm Beach are from the Estate Series (aluminum impact), Sentinel Series (vinyl impact), and Targa Series (high-rise aluminum). The Estate 200 and 400 lines use a distinct sash balance and keeper geometry that changed in 2019, so a part pulled from a 2017 unit will not seat correctly on a 2021 frame. We verify this with a sightline measurement, not guesswork.
OEM parts from CGI come with the original finish match and warranty registration, but lead times can run 4 to 6 weeks for discontinued series. We also source quality aftermarket equivalents from CWS and ES Windows hardware catalogs when the original is back-ordered, and we document the substitution in writing before ordering. If your label is worn, we measure the rough opening, track width, and glazing pocket depth to reverse-engineer the correct part. That measured survey becomes the quote you keep, and the quote becomes the invoice.
Signs Your CGI Window Replacement Is Failing

- The sash drops or won’t stay open. This usually means the coil balance or constant-force spring has lost tension. In West Palm Beach, salt air accelerates corrosion in the balance shoe, and we see this most often on east-facing units within three miles of the Intracoastal.
- Visible gaps at the meeting rail when closed. The interlock or weatherstrip has compressed past recovery, or the frame has shifted slightly in its opening. Either way, the impact rating is compromised and the U-factor climbs.
- Locking hardware sticks or spins freely. The multipoint lock mechanism has worn cam housings, or the keepers have drifted out of alignment from repeated thermal cycling. A forced closure will strip the gears.
- Condensation between panes. The insulating glass unit (IGU) seal has failed. This cannot be repaired; the entire glazed sash must be replaced to restore the SHGC and visible transmittance ratings.
- Frame corner separation or weep hole blockage. Water intrusion at the sill joint causes aluminum oxidation or vinyl degradation. We see this in West Palm Beach homes where landscaping sprinklers hit the frame directly.

| Component | Typical Range (West Palm Beach) |
|---|---|
| CGI sash replacement (Estate Series) | $380 - $620 |
| CGI sash replacement (Sentinel Series) | $440 - $780 |
| Full frame replacement with CGI unit | $890 - $1,200 |
| IGU replacement (glazed sash) | $520 - $850 |
| Hardware set (lock, keepers, balances) | $180 - $340 |
The range reflects three variables: whether the existing frame is square within 1/8 inch, whether the original series is still in production, and whether the wall condition requires reframing. Our quote includes the measured survey, the part, the labor, the disposal, and the photo record. If the number isn’t on the page, it isn’t in the price. The 365-Day Done Right Promise covers the installation; manufacturer defects are handled through CGI’s warranty channel, which we manage for you.
DIY or Call Us?

A homeowner can safely check the label location, clear weep holes with a pipe cleaner, and confirm the lock engages fully without forcing it. Beyond that, CGI window replacement involves tempered or laminated glass under pressure, and the sash can weigh 40 to 90 pounds depending on the series. Removing a sash without supporting the frame risks glass breakage and personal injury.
We have also seen DIY attempts where the replacement balance was correct but installed with the wrong tension, causing the sash to slam shut. That is a finger hazard and a code violation. Our crews carry the tension gauges and the specific keeper shims for each CGI series. Call (561) 354-3861 to schedule the measured survey; the written estimate is free and we will show you exactly what failed and why.
FAQs
CGI aluminum frames typically last 25 to 30 years with proper maintenance; hardware and seals need attention at 10 to 15 years in coastal Florida. Salt air, UV exposure, and seasonal humidity cycling wear the balances and weatherstripping faster than inland climates. Call (561) 354-3861 for an exact quote on replacement - estimates are free.
Hardware, balances, and weatherstripping can often be repaired or swapped. A failed IGU or bent frame rail requires full sash or frame replacement to maintain the impact rating and warranty. We will tell you which category your unit falls into during the measured survey. Call (561) 354-3861 for an exact quote - estimates are free.
Once the part is on-site, a single sash replacement takes 45 to 90 minutes; a full frame replacement takes 2 to 4 hours per opening. We schedule the install only after the measured survey confirms the spec and the part is in hand. Call (561) 354-3861 to schedule your free estimate.
We stock common Estate and Sentinel hardware, balances, and keepers on our trucks. Specialty sizes and discontinued series are ordered after the measured survey, with typical lead times of 3 to 10 business days. We do not charge storage or rush fees.
