CGI Impact Garage Doors: The Jupiter Owner’s Guide

We stock and install CGI-compatible impact garage doors across Jupiter, with installed prices typically ranging from $2,800 to $5,400 depending on door size, wind-load rating, and hardware package. Most standard single-car replacements can be surveyed and quoted same-week; double-car and custom-height units usually run 10-14 days from measured survey to installation. Most Jupiter homeowners discover their CGI impact garage door is failing when the opener strains, the door hangs uneven in the tracks, or they notice daylight seeping through a cracked glazing insert after a summer storm - symptoms that start small and accelerate once the torsion spring or impact-rated panel loses integrity.

Which CGI Models This Applies To

CGI’s impact garage door program centers on the Estate Series and Sentinel Series, both engineered for Florida’s HVHZ (High Velocity Hurricane Zone) requirements. The Estate Series carries a 9/16-inch impact-rated glazing insert with a 6.5 psf design pressure rating; the Sentinel Series steps up to 7.5 psf with a heavier-gauge aluminum frame and reinforced corner joints. We also service discontinued CGI lines including the early Guardian Series (pre-2018), though parts availability for those units requires a measured survey to confirm.

To identify your model, check the interior side of the top rail for a stamped aluminum tag - usually 2 inches by 3 inches, riveted near the left hinge stack. The tag lists the series code (EST, SEN, or GDN), the nominal door size, and the wind-load zone certification. If the tag is missing or painted over, we measure the panel thickness (Estate runs 1-3/8 inch, Sentinel runs 1-3/4 inch) and the glazing pocket depth to determine compatibility. OEM hardware from CGI is available through their Florida distribution center in Lakeland with a 5-7 day lead time; for hardware-only repairs we often specify heavy-duty aftermarket equivalents from Clopay or Amarr that meet the same Miami-Dade NOA standards at roughly 60 percent of OEM cost. The one compatibility gotcha we see in Jupiter: Estate Series doors from 2016-2019 used a proprietary 2-inch track radius that does not accept standard 3-inch radius rollers without rail modification. We check this on every survey - no exceptions.

Signs Your CGI Impact Garage Door Is Failing

• The opener labors or reverses mid-cycle. This usually traces to a weakening torsion spring or seized roller bearings. In Jupiter’s salt-air environment, we regularly see roller corrosion within 4-6 years on beach-adjacent homes, well short of the 10-year rating.
• Daylight visible through cracked or fogged glazing inserts. The impact-rated laminated glass has failed its seal, or the polycarbonate insert has stress-fractured from thermal cycling. Once moisture enters the laminate, the interlayer delaminates and the panel loses its missile-impact rating.
• The door hangs crooked or binds in the tracks. A failing cable drum, worn hinge, or bent bottom fixture is the typical cause. On CGI Sentinel Series units, the heavier 1-3/4-inch panel puts more load on the hinge stack; we find cracked hinge mounts on roughly 30 percent of Sentinel surveys past year seven.
• Rattling or whistling during wind events. Weatherstrip compression set or missing retainer screws along the meeting stile. Jupiter’s easterly exposure along the Intracoastal sees sustained 25-35 mph winds that accelerate wear on vinyl bulb seals.
• Remote intermittently fails or the wall button flashes. Often misdiagnosed as an opener problem, this frequently stems from a misaligned safety sensor knocked loose by a binding door section. The root cause is mechanical, not electrical.

Replacement Cost & What’s Included

For Jupiter installations, our measured survey produces a written scope with line-item pricing before any work is authorized. Single-car CGI Estate Series replacement: $2,800-$3,800. Double-car Estate or single-car Sentinel: $3,600-$4,800. Oversized or custom-height units with upgraded hardware packages: $4,200-$5,400. These ranges include door removal and disposal, new heavy-duty galvanized track (we do not reuse old track on impact-rated installs), professional alignment, and opener reconnection.

What drives the spread: wind-load certification required (Miami-Dade NOA vs. standard Florida Product Approval), glazing upgrade from standard laminated to low-E insulated, and whether the existing opener can handle the new door’s weight or requires replacement. Every job carries our 365-Day Done Right Promise under the Haven Standard, and we leave a documented photo record of the installed assembly, the track fastener pattern, and the final balance test. No change orders, no invoice surprises - Haven Clause 1.

DIY or Call Us?

There is one place we draw a hard line: torsion spring systems on impact-rated garage doors store lethal energy. A standard 16-foot double-car door spring is wound to roughly 10,000 pounds of torque. We have replaced doors where a homeowner’s DIY spring release cracked the top panel, stripped the cable drum, and turned a $400 hardware repair into a full door replacement. Do not attempt spring, cable, or bottom-bracket work yourself.

What you can safely check: verify the opener is plugged in and the photo-eye lenses are clean and aligned (both LEDs should glow steady, not blink). Lubricate the hinge pins and roller stems with silicone spray - not WD-40, which attracts grit. Beyond that, the precision matters. Measure once, quote it straight, install it right - that’s the whole business. Call (772) 362-5402 to schedule your free measured survey; we will read the rough opening, identify your CGI series, and hand you the written price before a tool is lifted.
