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

We stock and install CGI-compatible sliding and patio door systems in Tamiami, with typical installed replacement pricing running $1,800-$4,200 depending on series, glazing package, and whether the opening requires impact-rated product per Miami-Dade NOA. Most CGI sliding door failures we see in Tamiami involve roller assemblies, locking hardware, or weatherstripping degradation, and we carry common CGI replacement components on our service trucks. The symptom that usually brings a homeowner to call: the door sticks, drags, or won’t lock securely, often after a tropical weather season or years of trail dust working into the track system.

Which CGI Models This Applies To

CGI’s sliding and patio door lineup breaks into three series most common in South Florida installations: the Estate Series (aluminum frame, non-impact), the Sentinel Series (impact-rated, HVHZ certified), and the Targa Series (premium impact with multi-point locking). The label you need is the etched mark on the glass spacer or the interior frame sticker, usually located on the fixed panel edge or top track housing. It will read something like “CGI-ES-XX” or “CGI-SEN-XX” followed by a date code.

Here’s where matching gets specific: CGI changed roller housing dimensions between 2016 and 2019 production runs. The older Estate Series used a 1-1/4 inch stainless roller with a flat-profile axle bracket; post-2019 units shifted to a 1-1/2 inch tandem roller with an angled bracket that sits deeper in the sill track. Order the wrong one and the door sits proud of the threshold, leaking air and water. We carry both configurations on our Tamiami trucks, and we verify with a physical sample before ordering anything we don’t stock.

OEM CGI hardware comes through their Florida distribution network with a 2-3 week lead time on some lock sets. We also source verified aftermarket equivalents from Truth Hardware and Amesbury that meet the same cycle-testing standards and carry comparable finish warranties. For impact-rated units, we do not substitute non-OEM glazing or frame components; the NOA documentation chain matters for resale and insurance, and we keep that paperwork intact.

Signs Your CGI Sliding or Patio Door Is Failing

• The door drags or requires shoulder pressure to move. This usually means the roller assembly has flat-spotted bearings or collected enough trail grit in the housing to seize. In Tamiami, we see this accelerate when homeowners pressure-wash tracks without protecting the roller axles; water intrusion past the axle seal washes out lubricant and starts corrosion within a season.
• Visible daylight or water intrusion at the sill or jamb. The pile weatherstripping compresses permanently after 5-7 years of Florida UV exposure, and the sill dam or weep system may be clogged with debris. On CGI units with a recessed track, standing water that doesn’t drain within 24 hours of rain points to blocked weep ports or a compromised sill pan.
• Lock lever operates but doesn’t engage the keeper. The multi-point locking system on Sentinel and Targa series uses a concealed rod mechanism; when the door sags on worn rollers, the rod tips miss the keeper strikers by an eighth of an inch and the handle feels mushy. Adjusting the roller height sometimes fixes this; other times the rod itself has bent from repeated forced closure.
• Glass fogs between panes. This is seal failure in the insulated glass unit, not a frame or hardware issue, but it’s worth noting because CGI’s warranty on glass seal failure runs 20 years from manufacture date on most series. We document the etched date code and handle the warranty claim directly when applicable.
• Frame corner gaps or sealant separation. Thermal expansion in South Florida puts cyclic stress on aluminum frame corners. A visible gap at the head-jamb corner or separated back bedding means the frame is no longer square and the door will never seal properly until the unit is re-squared or replaced.

Replacement Cost & What’s Included

For Tamiami, our installed pricing on CGI sliding and patio door work breaks down as follows:

What drives the range: single-panel versus multi-panel configurations, impact-rated versus non-impact glazing, and whether the existing frame opening is plumb and square or needs reframing. Every Tamiami job starts with our measured survey, which the customer keeps. The written quote derived from that survey is the same document that governs the final invoice; Haven Clause 1 means no change orders for conditions we should have caught at measurement. Our 365-Day Done Right Promise covers the installation and hardware function, and every job leaves a documented photo record of before, during, and after.

DIY or Call Us?

There are two things a Tamiami homeowner can safely check without tools: whether debris is visible in the track (remove it with a vacuum crevice tool, not a screwdriver that will score the stainless track), and whether the weep holes at the sill exterior are blocked (clear with a pipe cleaner, never compressed air that can blow debris into the frame cavity).

Everything else carries risk. The roller assemblies on CGI sliding doors support 80-120 pounds of panel weight; releasing the adjustment screw without supporting the panel can drop glass abruptly. Multi-point lock mechanisms store spring tension in the rod system; disassembly without knowing the release sequence can launch components. We are not affiliated with CGI; we are an independent service provider with no manufacturer obligation to steer you toward full replacement when a component fix will serve. If you have a written estimate from another contractor, we will review it at no charge and tell you whether the scope matches what we find on site. Call (786) 321-9118 to schedule.
