CGI Sliding & Patio Doors: The Kendall Owner’s Guide
CGI sliding and patio door replacement in Kendall typically runs $2,800-$6,400 installed, depending on the series, size, and whether you’re swapping a standard unit or an impact-rated panel. We stock CGI-compatible rollers, tracks, handles, and locking assemblies on our trucks, and we carry full replacement units for the Estate and Sentinel series in common sizes. Most Kendall homeowners realize their CGI door is failing when the panel sticks in the summer humidity, the lock won’t engage after a storm, or they notice daylight showing through the weatherstrip after years of UV exposure.
Which CGI Models This Applies To
CGI’s sliding and patio door lineup breaks into three tiers, and the parts are not interchangeable between them. The Estate Series uses a heavier extrusion with a stainless steel roller carriage rated for panels up to 200 lbs; the Sentinel Series shifts to a lighter aluminum frame with polymer rollers for standard-duty applications; the Targa Series sits between them with a hybrid roller system and a narrower interlock profile. We see the most calls in Kendall for Estate and Sentinel units installed between 2012 and 2019, the years when CGI dominated the South Florida market after the building code changes.
To identify your series, check the etched mark on the glass spacer bar visible when the door is open, or look for the stamped label on the frame head jamb. The Estate roller assembly measures 1-1/4 inch wheel diameter with a 7/16 inch axle bore; Sentinel uses a 1-inch wheel with a 3/8 inch bore. Mixing these up destroys the track in about six months of use. We source OEM rollers and tracks directly from CGI’s Florida distribution center, though we also stock quality aftermarket equivalents from C.R. Laurence for same-day repairs when the OEM lead time stretches past a week. Sightline Windows & Doors Kendall is an independent service provider, not affiliated with CGI.
Signs Your CGI Sliding & Patio Door Is Failing

- The panel drags or requires two hands to move. This usually means the roller carriage has seized or the wheels have flat-spotted from sitting in one position through a wet season. In Kendall, we see this accelerate when owners pressure-wash the track and force water into the bearing races.
- The lock thumbturn spins without engaging the deadbolt. The Estate Series uses a multi-point lock with a concealed gearbox; when the internal cam wears, the handle feels normal but nothing catches. We replace the gearbox, not the whole lock set, unless the faceplate has corroded.
- Daylight or water intrusion at the sill. The weatherstrip pile on CGI’s older units compresses permanently after four to six years of South Florida sun. We measure the kerf width with a feeler gauge and match the replacement pile to the thousandth of an inch.
- The track itself is gouged or dented. A failed roller drags metal on metal, and once the track profile is compromised, new rollers will not ride true. Track replacement requires removing the fixed panel, which is a two-technician job on Estate units over 8 feet wide.
- Condensation between the glass panes. This indicates seal failure in the insulated glass unit. CGI’s standard warranty on glass is ten years, but many Kendall installations from the mid-2010s are now outside that window. We measure the sightline and order a replacement IGU to the exact cut size.

The range reflects three factors: whether the opening requires reframing, if the existing flange is intact enough to reuse, and whether the replacement unit needs to match a specific interior finish. Every quote we write in Kendall starts with a measured survey you keep, and the final invoice matches that document exactly. Haven Clause 1, Have it in writing, means the price cannot change once work begins unless you add scope. The 365-Day Done Right Promise covers all labor, and we leave a documented photo record of the completed installation.
DIY or Call Us?

There is one thing a Kendall owner can safely check: remove the panel stop trim and inspect the roller carriage for visible corrosion or debris. If the wheels turn freely and the carriage isn’t cracked, a thorough track cleaning with a dry nylon brush may restore operation.
Everything else benefits from a second set of hands and the right tools. Estate Series panels weigh 150-200 lbs; tilting one to access the rollers risks glass breakage or back injury. The multi-point lock gearbox requires precise shim alignment or the deadbolts won’t seat in the keepers. Track replacement involves cutting the old track without damaging the sub-sill, then setting the new track to a level within 1/16 inch over the full width. We carry the specific CRL track bender and CGI’s factory shims on every truck. Call (786) 321-3319 to schedule your free estimate; we’ll bring the measured survey and the written price to your door.
FAQs
In South Florida’s salt-air environment, expect six to ten years on Estate Series stainless rollers, four to seven on Sentinel polymer units. Units facing direct west sun or within a mile of Biscayne Bay tend toward the shorter end. Call (786) 321-3319 for an exact quote on replacement - estimates are free.
Sometimes. If the thumbturn operates but the deadbolts don’t extend, the internal gearbox has failed and we replace that component alone. If the faceplate or keepers have corroded, full lock set replacement is the only reliable fix. Call (786) 321-3319 for an exact quote - estimates are free.
Most CGI sliding door removals and replacements in Kendall finish in one day, assuming the rough opening is sound and the finish trim doesn’t require custom matching. Impact-rated Estate units with integral blinds add a half-day for adjustment and testing. Call (786) 321-3319 to schedule your free estimate.
We carry rollers, tracks, weatherstrip pile, and multi-point lock gearboxes for Estate and Sentinel Series on every Kendall route. Full door units require a factory order with a two-to-four-week lead time, though we maintain a small inventory of common Sentinel sizes at our warehouse. Call (786) 321-3319 to confirm availability for your specific model.
We also stock and install parts for PGT, CWS, and ES Windows sliding and patio doors.
