CGI Sliding & Patio Doors: The Miami Owner’s Guide
CGI sliding and patio door parts in Miami typically run $140 to $680 installed depending on whether you need rollers, a handle set, a lock assembly, or a full track replacement, with most common repairs completed in one visit. We stock CGI-compatible components on our trucks and source OEM parts directly when a specific series requires it. Most Miami homeowners discover a part has failed the same way: the door starts dragging across the track in August, the lock won’t throw cleanly, or the handle feels loose enough that you stop trusting it during a storm warning. By the time you feel it, the wear has usually been building for years.
Key Takeaways:
- CGI parts are series-specific; a Series 1000 roller will not seat correctly in a Series 7000 frame.
- Salt air and humidity kill track hardware faster in Miami than almost any other market in the country.
- The part that fails first on most CGI sliders is the roller assembly, followed by the lock pawl.
- We are an independent service provider, not affiliated with CGI, but we install and match their parts to factory spec every day.
Which CGI Models This Applies To
CGI’s sliding and patio door lines break into a few families you will see across Miami homes: the Series 1000 and 2000 aluminum sliders common on condos built before 2005, the heavier Series 7000 and 8000 impact-rated doors on newer construction and retrofits, and the Estate Collection multi-slide doors on higher-end waterfront properties. Each family uses different roller carriage widths, different track profiles, and different handle backset dimensions. A Series 2000 roller is narrower than a Series 8000 roller by roughly a quarter inch, and forcing the wrong one into a track gouges the anodized surface and binds the door within months.
Before we order or pull anything from the truck, we read the sticker. CGI etches or labels every sash with a model number, usually on the edge rail or the interlock where the two panels meet. The label tells us the series, the glass make-up, and the production date, which matters when a door is under warranty or when a mid-cycle design change means the newer handle set won’t line up with the older mortise pocket. When OEM is required for a warranty or an insurance claim, we wait the lead time and charge for the part, not a markup on a markup. When a quality aftermarket equivalent makes sense and holds to the same load rating, we quote both on paper and let the homeowner decide. Some things we will not substitute: impact-rated lock cylinders, reinforced interlock hardware, and any component that affects the door’s structural rating in a storm.
Signs Your CGI Sliding & Patio Doors Is Failing
- The door is hard to push, even after cleaning the track. This almost always means the rollers are flattened or seized. Nylon wheels wear into an oval shape over time, and once they stop rolling, they start scraping. Miami humidity accelerates the corrosion on the steel axles inside the wheel.
- The handle lifts but the door does not unlock. On CGI doors, the handle operates a pawl and hook assembly inside the jamb. When the spring inside the handle mechanism breaks, the handle moves without engaging. This is a small part, but it means the door is not actually securing anything.
- The door sags toward the latch side and leaves a gap at the top. Rollers are load-bearing. When one side fails, the panel drops. You will see daylight or feel air movement along the top rail, and the door will bind on the lower track. Running a door in this condition bends the track over time and turns a roller job into a track replacement.
- The lock throws only halfway and stops. In Miami, this is usually corrosion inside the lock body or misalignment from a sagging panel. The strike plate in the jamb shifts, and the lock bolt hits the edge of it. Forcing the handle bends internal linkage and breaks the tailpiece.
- You hear gravel grinding when the door moves. Sand, salt, and debris work into the roller assembly. That grinding is the sound of delrin plastic and aluminum being chewed into powder. Ignoring it means the axle will eventually seize, and the wheel will drag flat on the track and carve a groove into it.
Replacement Cost & What’s Included
In Miami, the installed price for most CGI sliding and patio door repairs lands between $140 and $680. Roller replacement on a standard two-panel slider is the lower end of that range: four rollers, cleaning and re-aligning the door, and labor. A complete handle and lock set, including the exterior cylinder and interior latch hardware, runs higher because the parts themselves are more expensive and the mortise pocket sometimes needs re-cutting. Full track replacement is the upper end, and that happens when a seized roller has been run over the track long enough to wear through the anodizing.
What is included: the part, the labor to install it, adjustment so the door seats square in the frame, and our workmanship warranty. We do not add a trip charge on top of a repair, we do not pad the part cost, and the price we quote before we start is the price on the bill. Every job is covered by the Done Right Promise. If the fix does not hold, we come back and make it right without a fight about it.
CGI Sliding Door Repair Cost Ranges, Miami:

- Handle and lock set replacement: $180 – $410
- Track realignment and hardware adjustment: $120 – $280
- Full track replacement: $380 – $680
DIY or Call Us?
You can safely clean the track, vacuum loose debris out of the sill, and check whether the door sits level by eye. What you should not do is pull the panel out of the frame yourself. A sliding glass panel in a CGI impact door is heavy, and the moment the rollers leave the track, that panel wants to tip. If it goes over, the glass shatters, the frame twists, and you have a much bigger bill than the roller job ever was. Torsion in a raised panel, even a partially raised one, is exactly what it sounds like: stored energy looking for somewhere to go.
What we can tell you over the phone, after a few questions: whether it sounds like rollers or a track problem, whether the part you describe is likely something we have on the truck, and an honest range for what it will cost. We will not tell you a final price sight unseen, because a door that sounds simple over the phone is sometimes hiding a bent interlock or a failed weld. But we will tell you what we think, and we will be there when we say. Call (754) 238-2201 if you want a set of eyes on it.
FAQs
In Miami’s salt air and humidity, you can expect 8 to 15 years out of a set of OEM CGI rollers before they start to flatten, corrode, or bind. Doors facing open water or exposed to direct afternoon sun on a canal or bayfront property sit at the lower end of that range. If a door is opened and closed several times a day, the clock runs faster still. When a roller set is replaced, we clean the track, check the alignment, and tell you honestly how much life is left in the track itself. If the answer is not much, you will know before we leave. Call (754) 238-2201 for an exact read on your door.
In most cases, no. Once the nylon wheel has worn flat, re-rounding it is not a thing, and lubricating a flattened wheel just turns nice grease into a sand paste. The axle inside the carriage corrodes in our coastal air, and by the time a door noticeably drags, the roller set is done. Replacement is the repair. The exception is when only one side of a dual-wheel carriage is worn and the carriage is still structurally sound; even then, the labor to rebuild rarely saves money over replacing the set.
Most single-part replacements take under two hours from arrival to final adjustment. Rollers, handle sets, and lock assemblies on the common CGI series are jobs our technicians do regularly, and we carry the most common components on the truck. If a track needs to be ordered or a specialty finish matched, the job becomes two visits: one to measure and confirm the part, and one to install. We quote that on paper before anything is ordered so there is no surprise between the estimate and the bill.
We stock the parts that fail most often on CGI sliding doors in Miami: roller carriages for the Series 1000, 2000, 7000, and 8000, lock assemblies, handle sets, keeper plates, and adjustment hardware. Specialty finishes, custom glass stops, and non-standard track profiles are ordered from the manufacturer or an approved aftermarket source. When we order, we give you the lead time straight, and we register the part against your serial number so the warranty clock starts on the day it goes in, not the day it leaves the warehouse. We also stock compatible parts for Andersen, and Pella doors, though this page is about CGI-specific work.
If your CGI sliding or patio door is dragging, sticking, or refusing to lock and you want a straight answer about what it will take to fix it, call (754) 238-2201. We will ask a few questions, give you a range, and schedule a time that works. Estimates are free, and the price we quote is the price you pay. We have been doing this in South Florida for a long time, and we plan to be doing it here for a long time more.
