CGI Window Installation: The Davie Owner’s Guide
CGI window installation in Davie typically runs $890-$2,400 per opening depending on series, impact rating, and whether the job is a retrofit into existing frames or a full-frame replacement with stucco repair. We stock CGI’s most common sash, frame, and hardware configurations for same-day installation on standard sizes. Most Davie homeowners discover their CGI window needs attention when they feel salt-air draft around the sash, spot fog between impact-laminated glass layers, or find the lock hardware has corroded after a humid summer.
Which CGI Models This Applies To
CGI manufactures three primary residential lines we install in Davie: the Sentinel series (non-impact vinyl), the Estate series (aluminum impact-rated), and the Targa series (high-velocity hurricane zone, Miami-Dade and Broward approved). The label you need is inside the frame channel, visible when the sash is tilted or removed, showing a six-digit SKU beginning with ES-, SE-, or TG- followed by the glass spec code.
Here’s where owners get stuck: Estate series hardware from 2015-2019 used a proprietary mortise lock with a 7/8-inch backset that CGI revised in 2020. The new part looks identical but carries a 1-inch backset. We carry both on the truck, and we measure before ordering anything. For impact glass, OEM laminated units are built to CGI’s exact interlayer spec, but we also source equivalent laminates from PGT and CWS when CGI’s lead time stretches past three weeks. The U-factor and SHGC ratings must match your original NFRC label, or your energy compliance certificate becomes invalid. That’s documented on every replacement we do.

Signs Your CGI Window Installation Is Failing

- Fog or haze between glass panes. In Davie’s coastal climate, the dual-seal system on older CGI units eventually admits moisture through the spacer bar. Once the desiccant saturates, the view clouds permanently. The glass unit needs replacement, not cleaning.
- Sash won’t lock or unlock smoothly. Salt air corrodes the zinc-alloy lock mechanisms in Estate series hardware faster than inland specs predict. We see this most in Pine Island Ridge homes within two miles of the drainage canals where humidity lingers.
- Visible frame separation or caulk failure. Thermal cycling between Davie’s 95-degree summer afternoons and 55-degree winter mornings stresses the frame-to-wall joint. Gaps here let water behind the stucco, and the repair scope grows quickly.
- Draft despite closed sash. Compression weatherstrip on CGI’s tilt-wash sashes hardens after 6-8 years of UV exposure. The gap is often less than 1/16 inch, but that’s enough to move conditioned air and raise your FPL bill measurably.
- Impact glass spider-cracking without breach. The polyvinyl butyral interlayer in CGI laminated glass can delaminate from edge moisture intrusion before the glass itself breaks. It still passes impact code, but the optical distortion means the unit has reached end of service life.

|---|---|---|
| Retrofit glass unit replacement, standard size | $890-$1,340 | Measured survey, OEM or equivalent laminate, removal/disposal, re-glaze, photo record |
| Full-frame replacement with stucco repair | $1,680-$2,400 | Frame out, new CGI frame, impact glass, stucco patch, paint match to 6 feet, permit pull |

| Weatherstrip replacement per sash | $140-$220 | Profile match, compression set verification, seasonal operation check |
What moves the number: stucco condition on full-frame jobs, glass size above 40 x 60 inches requiring two technicians, and whether the original installation used CGI’s nailing fin or a block-frame retrofit method. We don’t quote until we’ve measured. Haven Clause 1 means the price on your written scope is the price on the invoice. The 365-Day Done Right Promise covers labor and installation; glass carries the manufacturer’s warranty against seal failure, typically 10 years.
DIY or Call Us?

There’s a safe middle ground and a hard stop. Homeowners can verify the model label, photograph the failure, and check the NFRC sticker for glass specs. That information saves us twenty minutes on site and gets your parts ordered faster.
What we don’t recommend: removing an impact-rated glass unit yourself. CGI laminated glass runs 3/8 to 9/16 inch thick and weighs 6-8 pounds per square foot. A 36 x 48 inch sash exceeds 70 pounds, and the sharp edge on tempered lite can slice through standard gloves. More critically, improper handling voids the impact certification, and reinstallation without the proper glazing tape and setting blocks compromises the structural rating your windstorm inspection depends on. We’ve been called to three Davie homes in the past year where a DIY glass swap failed the reinspection and required complete redo.
Measure it right the first time. Everything else follows from that. Call (754) 254-8492 and we’ll schedule a measured survey you keep, with a written price before any work starts.
FAQs
Impact-rated CGI units typically serve 20-25 years in Broward’s coastal environment, though hardware and weatherstrip need attention at 8-12 years. Salt air within three miles of the Intracoastal accelerates corrosion on Estate series locks; we inspect these annually for our maintenance clients. Call (754) 254-8492 for an exact condition check - estimates are free.
Impact-laminated glass cannot be field-repaired. Once the seal fails or the interlayer delaminates, the unit must be removed and a new laminated pane fabricated to the original CGI spec. We document the existing NFRC ratings and match them exactly. Call (754) 254-8492 for a written replacement quote.
Retrofit glass replacement in an existing CGI frame takes 2-3 hours per opening, including removal, disposal, and glazing. Full-frame replacement with stucco repair runs one full day for two openings, plus cure time before paint. We schedule to minimize wall exposure in case of Davie’s afternoon storms. Call (754) 254-8492 to book.
We carry Estate and Targa series hardware, standard weatherstrip profiles, and the most common glass sizes up to 40 x 60 inches. Custom sizes or Sentinel series vinyl parts typically order in 5-10 business days. Sonia Raman checks every truck inventory weekly against upcoming Davie appointments. Call (754) 254-8492 to confirm stock for your model.
