CGI Sliding & Patio Doors: The Coral Gables Owner’s Guide

If you have a CGI sliding or patio door with a part that’s failed or starting to go, we stock and install the replacement parts you need, and most jobs run between $280 and $950 installed depending on what’s worn out. We’re an independent service provider, not affiliated with CGI, but we’ve worked on their doors across Coral Gables long enough to know exactly which rollers, tracks, handles, and weatherstripping match which series. Usually, homeowners call us after the door starts dragging across the track, the lock stops lining up, or they notice daylight sneaking in around the edges. That’s the point where ignoring it stops being an option.

Which CGI Models This Applies To

CGI sliding doors in Coral Gables homes typically fall into a few series lines: the Estate Collection, the Targa series, and the Sentinel line, though we also see older CGI doors from the 1990s and early 2000s that predate some of the current naming. The easiest way to identify your door is to look at the corner of the glass or the edge of the door panel for the CGI etching and a small metal tag, usually on the top or bottom rail. That tag will give you the model, the manufacturing date, and sometimes the original glass make-up, which matters if you ever need a replacement panel down the road.

Here’s the compatibility gotcha most homeowners run into: CGI doors are not one-size-fits-all. The roller assemblies on a Sentinel door won’t necessarily slide into a Targa frame, and the interlocking weatherstripping profiles differ between series. We’ve had customers order parts online, guess the model, and end up with a roller carriage that’s a quarter-inch too tall and a door that binds worse than before. For OEM parts, the fit is exact but lead times can stretch. For quality aftermarket equivalents, we spec them against the original measurements, and on most Coral Gables jobs the aftermarket option performs just as well at a lower cost. We’ll tell you honestly which route makes sense for your door.

Signs Your CGI Sliding & Patio Door Is Failing

• The door drags or grinds when you push it. This is almost always a roller problem. South Florida humidity and salt air eat the bearings, and once they seize, the door rides on flat-spotted wheels that scrape the track. You’ll hear it before you see it.
• The door binds halfway open and won’t go further. Track misalignment or a warped bottom rail can cause this. In Coral Gables, we see frames settle over time on older homes, and the track drops just enough to catch the roller carriage.
• You can see daylight or feel air moving around the weatherstripping. The pile seal and vinyl sweeps on CGI doors dry out and compress after years of heat. When they’re gone, your air conditioning is leaking out too.
• The lock doesn’t catch, or catches only sometimes. The mortise lock or keeper can wear down, especially on doors that get heavy daily use. If you have to lift or push the door to get the lock to engage, the alignment is off.
• Water puddles at the door sill after heavy rain. This often points to a failed threshold seal or clogged weep holes in the track. In Coral Gables storms, water that can’t drain out will find its way inside.

Replacement Cost & What’s Included

For Coral Gables homeowners, the final installed price depends on what’s actually failed. A pair of replacement roller carriages and a track cleaning typically lands between $280 and $420. Replacing the threshold, weatherstripping, and adjusting the door for a tight seal runs closer to $400 to $650. Full hardware replacement, including a new handle set and mortise lock, can push toward $950 on high-end CGI Estate doors. The spread is driven by the part itself, how much corrosion we’re dealing with, and whether the frame needs realignment.

Every quote is a written line-item price. You’ll see the cost of parts, the labor, and that’s it. No change orders, no surprises on the invoice, and we don’t start until you approve the number. The work carries our Done Right Promise: if it’s not done right, we make it right. Ed’s name is on the door and on every job we do.

DIY or Call Us?

There are a few things you can safely check yourself. Look at the track and clear out any sand, shells, or debris that’s built up. Check that the weep holes on the exterior side of the track aren’t clogged. Those are the simple ones. Where DIY goes wrong is pulling the door panel out to replace rollers. A CGI impact door panel can weigh 150 pounds or more, and lifting it off the track without the right support damages the frame, the glass, or your back. We’ve repaired doors where someone tried, and the fix cost three times what the original roller replacement would have. If it’s more than debris on the track, call us at (904) 478-8983. We’ll tell you what’s going on and quote it straight.
