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

CGI sliding and patio doors in Miami Beach typically run $2,800 to $7,500 installed depending on series, size, and whether you’re replacing the door or just the failing hardware. We stock CGI-compatible rollers, tracks, handles, and weatherstripping on our trucks, and in most cases we can have a door sliding properly again in one visit. The way most Miami Beach homeowners find out something’s wrong is the same way we’ve seen it a thousand times: the door that used to glide with two fingers now takes a shoulder, or you feel a breeze through the seam on a still day, or the lock doesn’t catch the way it did when the house was new.

Here’s the thing about CGI doors in particular. They’re built for hurricane country, and that’s exactly why the parts fail in specific, predictable ways. The same impact-rated construction that makes the door strong also makes the panels heavy. Heavy panels wear out rollers faster than standard doors, especially in Miami Beach where salt air and fine sand work their way into the track. If you’ve noticed a change in how the door moves, acting now costs a lot less than waiting until the frame starts binding.

Which CGI Models This Applies To

CGI sliding doors come in several series, and the replacement parts are not all interchangeable. The main product lines we work with are the Estate Collection, Sentinel, Targa, and the older 700/800 series doors still on a lot of Miami Beach homes from the 1990s and 2000s. The single biggest compatibility gotcha we see: Estate and Sentinel use different roller carriage profiles than the Targa series, and a roller that looks close in a photo will bind on the track or leave the panel sitting too low. That’s why we always take the measurement off the old part before ordering a replacement, never off the door model alone.

OEM versus aftermarket is worth being honest about here. CGI’s OEM hardware is well-made and engineered to the door’s weight rating. There are quality aftermarket equivalents from suppliers like Prime-Line and SWISCO for common rollers and handles on older CGI doors, but on any door still under CGI’s warranty, using aftermarket parts can void that coverage. We quote both options on paper so you can see the price difference and make an informed call. Our rule is simple: if the door carries an active warranty, we use OEM parts and register the work. If the warranty has expired, we talk through what’s actually the best value for a Miami Beach door that’s already survived twenty-plus seasons.

Signs Your CGI Sliding Door Is Failing

• The door drags or requires real force to move. This almost always means the rollers have flat spots or the bearings are corroded. Miami Beach’s salt air is brutal on steel bearing races, and a door that drags today will eventually gouge the track, which is a much bigger repair.
• You feel air or see daylight at the meeting stile. The weatherstripping has compressed or the interlock has shifted. On a CGI impact door, this isn’t just a comfort problem. A compromised seal changes the pressure rating of the door in a storm.
• The lock or handle feels loose, or the door doesn’t latch cleanly. The latch mechanism has worn or the door has settled slightly. Forcing it closed day after day bends the keeper and eventually breaks the lock housing.
• The panel grinds or scrapes when it moves. Sand and salt grit get into the track and act like sandpaper on both the roller wheels and the aluminum track surface. By the time you hear it, the wear is already happening.
• The door has become noticeably harder to lock in summer. Aluminum frames expand in Miami Beach’s July heat. A door installed without proper clearance will bind at the top corner, which is a frame alignment issue, not just a worn part.

Replacement Cost & What’s Included

In Miami Beach, here’s what we see on a typical CGI sliding door repair:

• Roller replacement (both panels, including adjustment): $285 to $540
• Track cleaning, re-alignment, and roller replacement: $400 to $700
• Full hardware replacement (rollers, handle, lock, weatherstripping): $650 to $1,150
• Weatherstripping replacement only: $180 to $320

If the door itself needs replacing, a new CGI Estate or Sentinel sliding door in Miami Beach installed usually runs $3,200 to $6,800, and a larger multi-panel Targa configuration can reach $7,500 or more depending on size and finish. Every quote includes labor, the exact parts we’re installing, and cleanup. There are no surprise line items, no “while we’re in there” additions. Both warranty layers get registered in writing before our truck leaves your driveway. That’s the Keystone Standard, and it applies to every job we do.

DIY or Call Us?

There are a couple of things a Miami Beach homeowner can safely check on a CGI sliding door. You can clear sand and debris from the bottom track with a brush and vacuum, and you can wipe down the weatherstripping to see if it’s torn or compressed. But once you’re lifting a heavy impact-rated panel off its track, you’re dealing with a door that weighs anywhere from 150 to 300 pounds, and if it tips or comes off the rollers wrong, it can cause serious injury and damage the frame. That’s not a scare tactic. It’s the honest arithmetic of working with hurricane-rated doors.

We also say this plainly: most DIY roller replacements on CGI doors end with the panel sitting too low or too high because the adjustment screws were set by feel instead of by measurement. A door that’s a sixteenth of an inch out of alignment won’t seal right, and on an impact door, the seal is the whole point. If you’ve already tried the easy fix and the door still isn’t right, call (386) 406-9359 and we’ll get it done properly.
