CGI Sliding & Patio Doors: The Miami Owner’s Guide
CGI sliding and patio door replacement in Miami typically runs between $1,800 and $5,400 installed, depending on the series, size, and whether you’re replacing the entire panel or just the rollers, track, or locking hardware. We stock CGI-compatible parts on our trucks and can match most CGI sliding door components same-day when the part is in inventory. Most Miami homeowners discover they have a CGI door problem the hard way: the door starts dragging across the track in June, the lock stops catching, or a hurricane inspection flags the door as no longer meeting Miami-Dade code.

We’re an independent service provider, not affiliated with CGI. That matters because we’re not here to push a single product line. We’re here to match the part to the door you already own, price it straight, and install it so it holds up to Miami’s salt air and afternoon downpours. If you’re reading this, you’re probably not shopping for a whole new door. You’re looking for the right part, an honest price, and someone who answers the phone. That’s what this page is for.
Which CGI Models This Applies To
CGI builds sliding glass doors and patio doors across several product families, and the part you need depends on which series you have. The most common lines we work on in Miami are the CGI Estate Collection, the CGI Classic sliding door line, and the CGI Sentinel impact-rated series. Many Miami homes built after Hurricane Andrew carry CGI impact doors specifically because they meet Miami-Dade County’s strict wind-load requirements. If your door carries a Miami-Dade Notice of Acceptance (NOA) sticker, that sticker tells us more about your door than the model name ever will.
Here’s the compatibility gotcha most owners don’t know: CGI has changed roller and track specs across production years. A roller assembly that fits a 2005 CGI Estate door will not necessarily seat correctly in a 2018 unit, even if the door looks identical from the outside. The same applies to interlocking hardware and weatherstripping profiles. Before we quote anything, we pull the model number off the door’s edge or the manufacturer’s label on the frame, then we measure the roller housing and the track profile with a caliper. That’s the only way to know if we’re ordering the OEM part or a quality aftermarket equivalent that actually fits. Dale Kessler’s rule on this is short: measure twice, order once, and put everything in writing.
On the OEM versus aftermarket question for CGI specifically: OEM parts are typically the right call when the door is still under warranty or when the part is safety-critical, like impact-rated glass or reinforced locking hardware. For wear items like rollers, glides, and weatherstripping, a well-made aftermarket part from a supplier we’ve vetted over years in the field will often outlast the original at a better price. We’ll show you both options on paper and tell you honestly which one we’d put in our own house.
Signs Your CGI Sliding & Patio Doors Is Failing
- The door drags or sticks mid-track. This usually means the roller assemblies have flattened or the bearings have seized. In Miami, salt air accelerates this by corroding the steel internals of the roller wheels. You’ll feel the door bind in one spot, then free up.
- The door jumps off the track or rocks when you push it. A worn roller can disengage from the track, and once that happens the full weight of the door panel starts riding on the frame. On a CGI impact door, that’s a heavy panel, and the rocking motion will tear up the track channel quickly.
- The lock won’t catch or the handle feels loose. The interlocking stile and lock mechanism on CGI doors is a precise assembly. Years of slight misalignment from sagging rollers wears the lock components unevenly until they simply stop engaging. This is a security issue, not just an annoyance, especially on a ground-floor Miami patio door.
- Water seeps in around the bottom track during heavy rain. Miami’s summer downpours find every gap. If the weatherstripping or the track’s weep system is clogged or degraded, water pools at the base plate and works its way under the tile or flooring. We see this regularly in older Coral Gables and Pinecrest homes where the original track was never leveled properly.
- You hear grinding or a rattle when the door moves. Crushed bearings and loose glides make noise. It’s not a cosmetic issue; it’s the mechanical equivalent of a check-engine light. The longer a rough roller runs on an aluminum track, the more metal it removes.
Replacement Cost & What’s Included
For CGI sliding and patio door parts in Miami, here’s the honest range we quote on a daily basis:
- Roller assembly replacement (parts + labor): $180 - $420 per panel, depending on the series and whether the door must be removed from the frame.
- Track repair or replacement: $220 - $650 for a single-track section, more if the entire bottom track is pitted and must be replaced.
- Lock and interlock hardware replacement: $120 - $340, including realignment of the stiles so the new lock engages correctly.
- Full door panel replacement (impact-rated CGI glass): $1,800 - $5,400 installed, with the wide spread driven by panel size, Low-E options, and whether the frame is still square.
Every quote we write includes the part, the labor to remove and reinstall the door panel, clean-out of the track channel, and a written line-item breakdown before any work starts. No change orders, no “we found something else” surcharge. The 90-Day Done Right Promise covers our workmanship, and The Keystone Standard means both the manufacturer’s warranty and our labor warranty are registered in writing before our truck leaves your driveway. If it’s not done right, we make it right. No paperwork fight.
DIY or Call Us?
Some CGI sliding door issues are safe to check yourself. You can clean the track with a vacuum and a stiff brush, clear the weep holes with a wire, and check whether the door is visibly sagging by looking at the gap between the panel and the jamb. If the track is dirty or blocked, cleaning it may fix a dragging door without a service call.
But removing a CGI door panel is not a homeowner job. These panels are heavy, especially impact-rated ones, and the door is under tension from the top rollers and the interlock assembly. A panel that tips during removal can shatter, damage the frame, or hurt someone. Replacing a roller requires lifting the panel out of the track and laying it down carefully on a protected surface, then pressing out the old roller housings without bending the stile. We do this every week in Miami. If you’re not certain, call (561) 489-4036 and we’ll give you an honest read over the phone before we ever schedule a truck.
FAQs
In Miami’s salt air and humidity, original CGI rollers typically last 8 to 12 years before the bearings start to fail. Doors that face the ocean in neighborhoods like Key Biscayne or Brickell often need roller service closer to every 6 to 8 years. If your door is dragging and you’re not sure when the rollers were last replaced, call (561) 489-4036 for a free estimate.
Sometimes yes, sometimes no. A bent track can often be straightened and re-secured, and a lock mechanism that’s just out of alignment can usually be adjusted back into place. But a roller with crushed bearings or a cracked roller housing is a replace-only part. We’ll tell you which path makes sense for your door before we order anything.
Most roller and track replacements we complete in under two hours on site, including removal, cleaning, and reinstallation of the panel. Full panel replacements take longer because the glass is ordered to your exact size and Miami-Dade specifications. Call (561) 489-4036 and we’ll give you a straight answer on lead times for your specific door.
We stock the most common CGI roller assemblies, locking hardware, and weatherstripping profiles on our trucks because we service Miami homes every day. Less common series-specific parts may need a quick order from our supplier network, which also carries PGT, CWS, and ES Windows components. We’ll confirm stock before we schedule your appointment.
