AfterCGI Sliding & Patio Doors: The Miami Owner’s Guide
We stock, match, and install CGI sliding and patio door components throughout Miami, with most common repairs running $220 to $1,400 installed depending on whether it’s rollers, a lock, weatherstripping, or a full panel replacement. The parts are typically on our truck or at our supplier within one to two business days. Most Miami homeowners find the problem the same way: a door that used to glide with two fingers now takes a shoulder, the lock won’t throw, or water beads up on the tile after a hard August downpour.
Which CGI Models This Applies To
We handle parts and service for the full CGI sliding door lineup, including the Estate Collection, Sentinel series, and the Targa and S2000 impact-rated models common in Miami condos and single-family homes. The quickest way to identify your door is to check the corner of the glass for the etched CGI logo and a string of numbers. That string tells us the glass type, DP rating, and manufacturing date. Here’s the gotcha most people miss: CGI doors use proprietary roller assemblies that are not interchangeable with generic hardware-store parts, and getting the wrong roller carves grooves into the track. That’s a $400 mistake on a door that would’ve been a $95 fix. When a part is no longer available from CGI, we’ll tell you straight and offer a quality aftermarket equivalent only if we’ve installed it before and watched it hold up in Miami’s salt air. We’re an independent service provider, not affiliated with CGI, which means we’ll give you the honest compatibility call, not a brand-scripted answer.
Signs Your CGI Sliding & Patio Doors Is Failing
- It takes real effort to open or close. Rollers have flat-spotted or the bearings are packed with sand and salt. In Miami, we see this on doors as young as six years, especially on units facing the water.
- The door lifts or drops as it moves. The adjustment screws have backed out or the roller housing is cracked. That metallic scraping sound is the door riding on the track instead of the wheels, which means the track is next.
- Water appears on the interior floor after a storm. The interlocking weatherstripping or the threshold cap has degraded from UV and salt exposure. On impact-rated CGI doors, this is a warning sign, not a cosmetic issue.
- The multi-point lock won’t fully engage. The door has settled or the lock mechanism is gummed with corrosion. A door that doesn’t lock completely is no longer doing its hurricane job.
- Condensation or haze between the glass panes. The seal has failed and the argon or krypton fill is gone. That means the glass is doing less insulating and, on impact units, the pane is compromised.
Replacement Cost & What’s Included
Expect to budget these ranges for installed work in Miami:
- Roller replacement: $110 to $240 per panel
- Lock and handle set: $180 to $420
- Weatherstripping and threshold rebuild: $150 to $350
- Full panel or glass replacement (impact-rated): $900 to $1,400
Every quote is a written, line-by-line breakdown, so you see the part cost, the labor, and nothing else. The range exists because a 6000-series panel on a first-floor condo costs less than a 10-foot Estate Collection panel on a bayfront house with crane access. No change orders after work begins, ever. And every repair carries the 36500-Day Done Right Promise: if we didn’t do it right, we come back and make it right.
DIY or Call Us?
What you can safely do: keep the bottom track vacuumed, check for obvious debris in the rollers, and note exactly when the problem started and whether the door was hit or forced at any point. That information helps us. What you shouldn’t do: attempt to remove a door panel yourself. A CGI impact-rated panel can weigh over 200 pounds, and without the right lifting and realignment technique, you can damage the frame, crack the glass, or hurt yourself. The high-tension components and the weight involved mean this is a trained-professional job. If you’re in Miami and the door is binding or leaking, call (863) 862-5435 and we’ll schedule a diagnostic and get it gliding again.
FAQs
Rollers typically last 8 to 12 years in Miami’s salt air, locks 15-plus, and impact glass 20 or more. Coastal exposure shortens all of those numbers. If your door faces Biscayne Bay, expect to do rollers sooner than your neighbor inland.
Rollers are always replaced, never repaired; once the bearings are packed with sand and salt, they’re done. Locks can sometimes be cleaned and lubricated if caught early, but we’ll show you the wear before recommending a new set.
Most roller and lock swaps are done in under two hours on-site. Full panel replacements are scheduled after the glass arrives, which is usually one to two weeks from order in Miami.
We stock the most common CGI rollers, locks, and weatherstripping on our trucks. Specialty panels and odd-size glass are ordered direct, but we quote delivery time before you commit. Call (863) 862-5435 and we’ll check inventory for your specific model while you’re on the phone.
