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

Replacing the rollers, tracks, or lock hardware on a CGI sliding patio door in Miami typically runs $220 to $480 installed, depending on which component failed and whether we’re matching OEM or a quality aftermarket equivalent. Most hardware swaps take under two hours once the door is on the bench, and we keep the most common CGI replacement parts on the truck. What usually brings a homeowner to this page is a door that’s started dragging, a handle that won’t latch, or a roller that finally gave out after years of salt air and daily use.

CGI builds sliding doors to take a hurricane, but the moving parts are still moving parts. Rollers wear. Tracks collect sand and grit from the beach breeze. A door that fights you every time you open it isn’t just annoying in July, it’s telling you something specific. Here’s what you need to know before you spend a dollar on parts or labor.

Which CGI Models This Applies To

We work on CGI’s residential sliding glass door lines regularly, including the Estate Collection and the Classic Series, along with their impact-rated models that carry the Miami-Dade NOA. The compatibility gotcha with CGI is the roller assembly: CGI uses a few different roller housings across their production years, and the old door may have a stainless tandem roller or a single-wheel nylon unit depending on when it was built and which series it is. If you try to match by looks alone, you’ll end up with a roller that’s close but not right, and the door will never close square again.

To identify your door, look for the silver sticker or etched marking on the interior edge of the door panel, usually near the bottom corner or the lock stile. You’ll see a series name and a manufacturing code. Take a clear photo of that sticker and the bottom edge of the door where the rollers sit. That tells us more than a model name ever will. On the OEM-versus-aftermarket question, CGI hardware is well made but priced accordingly. For rollers and locks, we’re comfortable using proven aftermarket equivalents from suppliers we’ve vetted over the years. For anything structural, the frame, the impact glass, the interlock, OEM is the only conversation worth having. We quote both side by side on paper so you see exactly what you’re paying for, and we’ll tell you which one we’d put in our own house. TruePane Windows & Doors is an independent service provider; we’re not affiliated with CGI, but we’ve been installing and repairing their doors in the Miami market long enough to know which parts hold up and which ones don’t.

Signs Your CGI Sliding & Patio Doors Is Failing

• You’re using two hands and a hip to open it. The rollers are worn flat or the track is packed with grit. You shouldn’t need momentum to slide a patio door, and every forced open is doing more damage.
• The door lifts when it slides, then drops. The roller adjusting screws have backed out or the roller wheels have collapsed. That lift-and-drop motion wears the track and the rollers together, and the wear accelerates fast once it starts.
• You hear a grinding or scraping when the door moves. Either the bearings in the roller are gone or the track has developed burrs from years of sand and salt. Grinding means metal on metal, which means you’re shopping for a track next.
• The lock doesn’t catch, or it catches but won’t release. The door has settled or the lock stile is out of alignment. On an impact-rated CGI door, a misaligned lock is also a security problem, not just a lever that sticks.
• Water is getting past the threshold, especially in heavy rain. The door panel’s sag means it isn’t seating against the interlock or the weatherstripping at the head and sill. Water intrusion in a Miami home is a slow, expensive problem, and it almost always starts with a roller that should have been replaced a season earlier.

Replacement Cost & What’s Included

In Miami, expect to pay $220 to $340 for a pair of quality aftermarket rollers installed and adjusted, $260 to $420 for CGI OEM rollers, and $280 to $480 for a full lock and latch assembly replacement. A track replacement runs higher; $400 to $750 depending on length and whether we need to pull the panel. These are installed prices, not just parts. Labor, adjustment, and a clean bench are all in the number.

What drives the range is which series you have, how far the old hardware has damaged the surrounding components, and whether the panel needs to come out of the opening to do it right. We don’t have change orders on this kind of work. The quote you get before we start is the bill you sign when we leave. Every replacement is covered by our 90-Day Done Right Promise, and if the part has a manufacturer warranty, we register it in writing and hand you the paperwork. A square deal means the price is the price.

DIY or Call Us?

You can safely do the diagnostic part yourself. Check whether the door moves freely, whether the gap between the panel and frame changes as it slides, whether the lock throws cleanly. That tells you something. But swapping rollers on a CGI impact door means lifting a glass panel that runs anywhere from 150 to 250 pounds or more. If the panel tips or drops, you’re looking at broken glass, a bent frame, or worse. The panel is under tension against the track, and pulling it out alone is how homeowners end up with a door that never slides right again or a foot you don’t want to think about.

If you’ve got the equipment, a helper, and you’ve done it before, fine. If not, this is a job that costs less to hand to a professional than any mistake will cost to fix. We bring the right rollers, the right shims, and we set the door so it slides like it did the week it was installed. Call (561) 956-2754 and we’ll tell you over the phone what you’re likely dealing with and what it should cost to set it right.
