CGI Windows & Doors: The Boca Raton Owner’s Guide
We stock and install CGI-compatible windows and doors across Boca Raton, with most replacement parts available same-day and full unit swaps quoted at $4,500-$15,000 installed depending on series and opening count. For individual component failures - balances, locks, rollers, or weatherstripping - parts typically run $85-$340 plus labor, and we carry the common sizes on every truck. Most Boca Raton homeowners discover a CGI part has failed when a window won’t stay open in humid weather, the lock won’t engage after a storm, or they feel Atlantic breeze around a frame that used to seal tight.
Which CGI Models This Applies To
CGI manufactures under several series names, and the part you need depends on which line is installed in your home. The Estate Series uses a heavier extruded aluminum frame with a distinct 2-5/8 inch frame depth, while the Sentinel Series carries a slimmer 2-1/4 inch profile and a different roller pocket geometry. The WinGuard vinyl line, common in Boca Raton subdivisions built 2012-2019, uses proprietary balances that do not interchange with the aluminum series. To identify your unit, open the sash and look for the etched manufacturing label in the top track or the spacer bar between glass lites - the series code and manufacturing date are stamped there.
We source OEM CGI parts through the manufacturer’s Florida distribution network, though for discontinued series we specify quality aftermarket equivalents from Truth Hardware or Amesbury that match the original operating force and corrosion resistance. One compatibility gotcha we see regularly in Boca Raton: Estate Series locks from units manufactured before 2015 use a 3-1/2 inch hole spacing that changed to 3-3/4 inch in later production. Measuring the center-to-center dimension before ordering saves a second trip. We are an independent service provider, not affiliated with CGI.
Signs Your CGI Windows & Doors Is Failing

- The sash drops or won’t stay open. This points to failed coil balances or broken pivot bars, common in Boca Raton after 8-12 years of salt-air exposure. The balance spring loses tension gradually, so owners often compensate with a stick or prop before calling.
- Locking points misalign or the handle spins freely. The multipoint lock mechanism has internal cams that wear against the keeper; once the first cam slips, the others follow quickly. Humidity swells the frame slightly seasonally, which accelerates wear on marginal locks.
- Rolling patio panels jump the track or grind. The tandem roller assemblies collect sand and salt, then the axle pits. In Boca Raton, we see this first on south-facing sliders that catch afternoon sun and thermal-cycling stress.
- Visible daylight or air movement at the frame perimeter. Compression weatherstripping loses its memory in Florida heat, and the fin-seal pile along the sash edge mats down. The gap may be intermittent - tight when cool, leaky when the frame expands.
- Condensation between glass panes. The insulating glass unit seal has failed, admitting moist Atlantic air. This is not a part repair but a full sash replacement; the desiccant inside the spacer bar is saturated and cannot be restored.

AfterReplacement Cost & What’s Included
For full window replacement in Boca Raton, our installed range runs $4,500-$15,000 depending on unit count, series, and whether impact-rated glass is required. Individual component repairs are quoted flat: balance replacement at $180-$340 per sash, multipoint lock repair at $220-$480 per opening, roller assembly replacement at $160-$290 per panel, and weatherstripping renewal at $85-$190 per unit. These are parts-plus-labor numbers, written before work starts under Clause 1 of the Haven Standard.
What drives the range: accessibility (second-story access adds ladder time), the age of the unit (discontinued series require custom sourcing), and whether the substrate needs repair after part removal. Every repair carries our 365-Day Done Right Promise - if the new balance sags or the lock drags, we return and make it right. You receive a written warranty, a photo record of the work, and the signed scope before we start.
DIY or Call Us?

An owner can safely check a few things: verify the lock keeper is clear of debris, lubricate the track with silicone spray, and confirm the weep holes at the frame bottom are not clogged with sand. These are observation and maintenance tasks, not repairs.
Where DIY goes wrong: coil balances store significant tension and can release suddenly when the sash is removed without proper tools. The multipoint lock mechanism requires precise alignment of three or more locking points simultaneously; a misadjusted lock stresses the gearbox and fails again within months. And impact-rated glass units weigh 40-60 pounds per sash - dropping one damages the frame, the glass, and potentially the installer. We carry the tools, the parts inventory, and the liability coverage. Call (754) 254-8065 and we’ll schedule a free estimate with a written flat price before any work begins.
FAQs
Aluminum-framed CGI units typically last 20-30 years in Boca Raton’s coastal environment, though hardware components - balances, locks, rollers - need attention at 8-15 years due to salt-air corrosion and UV fatigue. Vinyl WinGuard series frames hold up well but the balances and weatherstripping follow a similar replacement cycle. Call (754) 254-8065 for an exact quote - estimates are free.
Some components can be serviced: lock keepers can be shimmed, track rollers can be cleaned and re-greased if the axle is sound, and weatherstripping can be replaced independently. Failed balances, fogged glass units, and cracked frames require full replacement - there is no reliable field repair. We assess this on-site and tell you which category applies before quoting. Call (754) 254-8065 for a free evaluation.
Most single-component replacements - one balance, one lock set, one roller pair - take 45-90 minutes on-site. Full sash or unit replacement runs 2-4 hours per opening, plus trim and sealant cure time. We schedule with a two-hour arrival window and send a photo confirmation when the technician is en route. Call (754) 254-8065 to schedule.
We carry the ten most common CGI hardware SKUs on every truck: balances for 22-36 inch sashes, multipoint locks for Estate and Sentinel series, tandem rollers for standard and heavy-duty sliders, and compression weatherstripping in the three standard frame widths. Less common or older-series parts are sourced overnight from CGI’s Florida distribution center. Call (754) 254-8065 - we’ll confirm availability when you book.
We also stock parts for KraftMaid cabinetry, Cambria and Silestone countertops, and maintain sourcing relationships across fifty-plus vetted brands so our written quotes reflect actual supplier pricing rather than inflated allowances.
