CGI Sliding & Patio Doors: The Florida City Owner’s Guide

We stock and install CGI-compatible sliding and patio door systems in Florida City, with typical installed replacement pricing from $1,850 to $4,200 depending on series, size, and impact rating. Most CGI rollers, tracks, and locking assemblies are available same-day from our Florida City inventory, and we carry the full suite of OEM and verified-equivalent hardware for the Estate, Sentinel, and Targa series. Homeowners usually discover a problem when the door sticks in the track during summer humidity, the lock no longer engages flush, or they notice daylight leaking through the weatherstrip after a storm season.

Which CGI Models This Applies To

CGI sliding and patio doors fall into three main series that we service across Florida City: Estate (non-impact, aluminum frame), Sentinel (impact-rated with laminated glass), and Targa (premium impact with reinforced interlocking stiles). The critical compatibility gotcha is this: Estate and Sentinel rollers share a 1-1/4 inch nylon wheel diameter, but Targa series uses a 1-1/2 inch stainless steel roller with a wider axle bracket. Install the wrong roller and the door sits high in the track, stressing the latch mechanism.

To identify your series, check the etched marking on the glass spacer bar or the embossed label on the frame header. The model number prefix matters: ES- for Estate, SE- for Sentinel, TA- for Targa. We stock OEM CGI rollers, tandem assemblies, and weatherstrip profiles, plus verified-equivalent hardware from Truth Hardware and Amesbury that matches the original specifications without the OEM lead time. For Florida City properties within two miles of Biscayne Bay or Homestead Bayfront Park, we typically specify stainless steel equivalents regardless of original equipment, because standard nylon degrades faster in salt-air environments. Measure it right the first time. The wall does not accept revisions.

Signs Your CGI Sliding & Patio Door Is Failing

• The door requires shoulder weight to move. This usually means the tandem roller assembly has flat-spotted or the axle bearings have seized. In Florida City, we see this accelerate when homeowners pressure-wash the track, forcing grit into the bearing races.
• The lock thumbturn rotates but the bolt does not throw. The internal cam linkage in CGI multi-point locks is zinc alloy and can shear after repeated cycling. Humidity corrosion at the mortise pocket makes this worse.
• Visible daylight between the active panel and the jamb. The pile weatherstrip compresses permanently after five to seven years in South Florida UV. Once the fuzz barrier fails, the door leaks air and driving rain.
• The track itself is gouged or corrugated. A failed roller drags metal across aluminum, destroying the track extrusion. Track replacement is a frame-level repair, not a hardware swap.
• Glass fogs between the panes. On Sentinel and Targa impact units, this means the warm-edge spacer has lost its butyl seal. The insulated glass unit must be remanufactured; defogging sprays do not work on laminated impact glass.

Replacement Cost & What’s Included

What drives the range: frame size, whether the opening requires impact-rated product per Florida Building Code, and whether the existing sub-sill is salvageable. Every Florida City quote we write starts with the measured survey you keep, and the final invoice matches that document. The 365-Day Done Right Promise covers all hardware and installation labor.

DIY or Call Us?

An owner can safely inspect the roller condition by lifting the active panel slightly and rotating the adjustment screw at the bottom rail. If the wheel turns freely and the adjustment still has travel, the assembly may just need cleaning. Where DIY goes wrong: CGI multi-point locks require precise backset and face-plate alignment; a mis-drilled mortise voids the frame warranty. Impact-rated panels weigh 80 to 140 pounds depending on size and cannot be safely handled without suction cups and proper bracing. We are an independent service provider, not affiliated with CGI. For anything involving glass handling or frame disassembly, our background-checked, uniformed technicians carry license numbers on record and work under Haven Clause 3 (Verified Crews).
