CGI Sliding & Patio Doors: The Jupiter Owner’s Guide

We stock and install CGI-compatible sliding and patio door systems in Jupiter, with typical installed replacement pricing from $2,800 to $5,400 depending on the series, glass package, and whether the opening needs reframing. Most CGI sliding door hardware assemblies and roller sets are on our trucks, and full panel replacements ordered from CGI’s Opa-locka facility generally arrive within 5-7 business days. Homeowners usually discover the failure when the door sticks in the track during humid mornings, the lockset won’t engage after a storm, or they notice daylight leaking through the weatherstrip after years of salt-air exposure along the Loxahatchee River corridor.

Which CGI Models This Applies To

CGI’s sliding and patio door lineup breaks into three series that handle different wind-load zones and frame depths. The CGI Estate Series uses a 2-5/8 inch frame depth with a flat sash profile; the CGI Sentinel Series carries a 3-1/4 inch impact-rated frame with a beveled sash; and the CGI Commercial Series steps to a 4-1/2 inch frame for multi-slide applications. The label you need is the etched mark on the glass corner or the stamped aluminum tag on the frame head - it lists the series, the design pressure rating (DP-50, DP-60, or DP-70 for most Jupiter installations), and the glass configuration.

Parts compatibility runs by series, not by door size. An Estate Series roller assembly will not seat correctly in a Sentinel track; the mounting bracket spacing differs by 3/8 inch, and the wheel diameter steps from 1-1/2 inch to 2 inch. We carry both OEM CGI hardware and quality aftermarket equivalents from Truth Hardware and AmesburyTruth where the spec matches. For impact-rated units, we specify OEM on any component that carries the missile-impact certification - the interlayer, the laminated lite, and the reinforced lock strike. For rollers, handles, and weatherstrip, aftermarket equivalents that meet AAMA 910 cycle testing perform identically at lower cost.

One compatibility gotcha we see regularly in Jupiter: homeowners with pre-2018 CGI doors often have the old-style mortise lock with a 7-5/8 inch backset. Current production uses 7-11/16 inch. The 1/16 inch difference sounds trivial until the latch misses the strike plate by a consistent margin. We measure the backset before ordering - Haven Clause 1 means the measurement and the quote travel together.

Signs Your CGI Sliding or Patio Door Is Failing

• The door drags or requires shoulder force to move. This usually means the roller assembly has flat-spotted or the axle has corroded. In Jupiter, salt air accelerates this - we see it first on east-facing doors within 6-8 years of installation.
• Water pools on the interior track after rain. The weep holes are blocked with debris, or the sill cap seal has hardened and lost compression. On ground-floor installations near Jupiter’s sandy soils, irrigation splash compounds the problem.
• The lock thumbturn rotates but the deadbolt doesn’t throw. The mortise gearbox has stripped, often from forcing the lock when the door is out of square. CGI’s current gearboxes use a zinc alloy housing that wears faster than the brass units they replaced in 2019.
• Visible gap at the meeting stile when closed. The adjustable strike has backed out, or the interlock weatherstrip has compressed past recovery. In Florida’s UV exposure, EPDM weatherstrip typically degrades in 8-12 years; silicone-treated versions stretch to 15.
• Condensation between the glass lites. The insulating glass unit (IGU) seal has failed. This is not a field-repairable condition - the sash or the full panel requires replacement, and the desiccant inside the spacer is already saturated.

Replacement Cost & What’s Included

The range reflects three variables: the series (impact-rated Sentinel costs more than standard Estate), the glass package (clear, Low-E, or Low-E with laminated impact layer), and whether the rough opening needs reframing. Every quote we write in Jupiter includes the measured survey you keep, the written scope with line-item pricing, and the 365-Day Done Right Promise stamped under Haven Clause 5 - No Surprises. The price on the page is the price on the invoice. We do not charge separately for the diagnostic visit when you proceed with the repair.

DIY or Call Us?

There is one task a Jupiter homeowner can safely handle: clearing weep holes with a pipe cleaner and verifying the track is free of sand and leaf debris. Beyond that, CGI sliding doors present two genuine hazards. The roller assemblies on impact-rated units are spring-loaded to maintain compression against the track; releasing the tension without proper support can snap the axle or damage the frame rail. More critically, any work that disturbs the glass panel on an impact-rated unit risks voiding the Miami-Dade NOA certification if the reinstallation is not documented to the original fastening pattern and torque spec.

We are an independent service provider - not affiliated with CGI - and we document every panel removal with frame readings, sightline measurements, and a photo record of the reinstallation. If you have already attempted a repair and the door is worse, we will assess it honestly and tell you whether it is salvageable before any work starts.
