CGI Door Installation: The Princeton Owner’s Guide
CGI door installation in Princeton typically runs $2,800-$6,400 depending on the series, impact rating, and whether the rough opening needs reframing. We stock CGI-compatible hardware and carry the common frame and jamb sizes on our trucks, so most installs start within 3-5 business days of the measured survey. Most Princeton homeowners realize their CGI door is failing when the sweep drags, the multipoint lock won’t engage, or they spot daylight between the frame and the wall after a storm season.
Which CGI Models This Applies To
CGI manufactures three door series we regularly install in Princeton: the Estate Collection (aluminum impact-rated entry doors), the Sentinel Series (impact-rated French and sliding doors), and the commercial-grade Targa line. The Estate and Sentinel use a proprietary 4-9/16″ or 6-9/16″ jamb depth depending on wall thickness, while Targa frames run deeper and require a different anchor pattern.
To identify your model, check the etched marking on the glass corner or the sticker inside the hinge jamb. The series code appears before the dash in the serial number. We match OEM hardware from CGI’s current catalog, though we also stock quality aftermarket multipoint locks and hinges from Truth Hardware and Hoppe when the lead time on CGI-branded parts stretches past two weeks. The aftermarket route saves roughly $180-$340 on hardware but voids any remaining CGI factory warranty on that component. For doors installed before 2018, watch for the old Estate latch mechanism with the rectangular faceplate; the current design uses a rounded Euro-profile that won’t retrofit without mortising the edge.
Signs Your CGI Door Installation Is Failing

- The door sticks or drags at the threshold. In Princeton, the seasonal ground shift between wet summers and dry winters throws off plumb on aluminum frames faster than vinyl. The bottom sweep compresses or the threshold cap loosens, and the frame itself may have settled if the original shim pack was sparse.
- Daylight visible around the frame perimeter. This means the seal gasket has hardened or the frame has pulled from the rough opening. On impact-rated CGI doors, this also compromises the pressure rating; the door may still latch, but it won’t perform under debris impact.
- Multipoint lock bolts don’t throw or retract smoothly. Salt air corrodes the internal linkage, especially on east-facing installations within two miles of the coast. The handle gets stiff, then the top bolt seizes, and eventually you’re forcing the mechanism until something cracks.
- Condensation between glass lites on a multipane unit. The IGU seal has failed. CGI uses a dual-seal system, but South Florida’s UV exposure and thermal cycling stress the butyl primary seal after 12-18 years. The glass unit needs replacement, not the whole door.
- Hinge screws backing out or frame flex at the hinge side. This indicates the original installer used standard wood screws instead of the longer structural screws CGI specifies for impact-rated weight. The door sags, the lock misaligns, and the weatherstrip tears from friction.

AfterReplacement Cost & What’s Included
| Component/Scope | Typical Range in Princeton |
|---|---|
| CGI Estate entry door, installed (standard size, single) | $2,800-$4,200 |
| CGI Sentinel sliding or French door, installed | $4,100-$6,400 |
| IGU replacement (glass only, failed seal) | $680-$1,240 |
| Multipoint lock hardware replacement | $340-$580 |
| Frame reflash and seal repair (no door replacement) | $580-$920 |
| Rough opening reframe (if out of square > 1/4″) | $420-$780 additional |
What drives the range: wall thickness (stucco vs. block), whether the existing frame comes out clean or needs cutting, and if the sill pan flashing was done correctly the first time. Every quote we write in Princeton includes the measured survey document you keep, the written scope with line-item pricing, and the photo record we deliver at completion. The 365-Day Done Right Promise covers labor and installation; CGI’s factory warranty covers the product itself. No change orders once the scope is signed.
DIY or Call Us?

There’s a short list of checks that won’t make things worse. Verify the hinge screws are tight with a proper driver (not a drill that strips the heads). Look for the CGI label to confirm your series before ordering any part. Check if the threshold cap lifts off by hand; sometimes debris packs underneath and a cleanout fixes the drag.
Where DIY ends: impact-rated doors weigh 80-140 pounds depending on size and glazing. The frame must be shimmed to hold square while structural screws are driven; if the frame racks during installation, the multipoint lock won’t align and the pressure seal fails. We have reframed three CGI doors in Princeton this year where the homeowner’s self-install looked straight to the eye but measured 3/16″ out of plumb. That variance doesn’t show until the lock bolts start chewing their strikes. Measure it right the first time, or measure it twice after the callbacks.
For a door that’s already failing, call (786) 977-2953 and we’ll schedule the measured survey. You’ll have the written price before we order a single part.
FAQs
Expect 18-25 years for the frame and hardware, 12-18 years for the insulated glass unit before seal failure. East-facing installations and those within a mile of open water see the shorter end of both ranges from salt corrosion and UV exposure. Call (786) 977-2953 for an exact quote on replacement - estimates are free.
Glass seal failure, hardware corrosion, and weatherstrip wear are all repairable. Frame cracks, hinge rail deformation, or pressure-test failure require full replacement. We assess both paths during the measured survey and price each in writing. Call (786) 977-2953 for an exact quote - estimates are free.
A standard CGI entry door replacement takes one day; a Sentinel sliding or French door with reframing takes two. We arrive with the product pre-measured and the hardware staged, so the opening isn’t exposed overnight. Call (786) 977-2953 to schedule.
We stock common Estate and Sentinel sizes in white and bronze; custom sizes, colors, or Targa commercial specs ship from CGI’s Doral facility in 4-6 weeks. We don’t start the clock until you’ve approved the written price. Call (786) 977-2953 to check current availability.
