CGI Sliding & Patio Doors: The Westchester Owner’s Guide

We stock and install CGI-compatible sliding and patio door parts across Westchester, with most rollers, tracks, locks, and handle sets running $180 to $620 installed depending on your series and what actually failed. If your door is grinding, dragging, or refusing to lock, we can usually diagnose it the same day and have the right part matched to your CGI model within 24 to 48 hours. Most Westchester homeowners discover the problem the hard way: the door gets harder to slide over a few months, then one morning it won’t budge at all, or the lock stops catching and suddenly the door that was supposed to be your hurricane barrier won’t seal against a summer squall.

Which CGI Models This Applies To

The parts we source cover CGI’s sliding glass door and hinged patio door lines, including the Estate Collection, the Classic Collection, and the CGI 9500 and 9600 series sliders that are common in Westchester homes built or renovated after Hurricane Andrew. Here’s the compatibility gotcha most people don’t know: a roller that fits a 9500 will not necessarily fit a 9600, because the 9600 series uses a heavier stainless-steel roller assembly designed for the wider, taller panels added to meet Miami-Dade impact codes. You’ll want the factory label off the door frame or the glass itself, which lists the series, production date, and impact-zone rating. We match OEM parts whenever the door is still under warranty or the homeowner specifically requests them; for out-of-warranty doors, we often recommend a quality aftermarket equivalent from the same Southeast manufacturers CGI sources from, which typically saves 20 to 35% without changing the door’s rating or fit. Winslow Windows & Doors is an independent service provider, not a CGI dealer, so our only interest is what fits your door correctly and holds up in salt air.

Signs Your CGI Sliding & Patio Door Is Failing

• Grinding or a gravel-like feel when you slide the panel. The roller bearings have corroded or flattened. In Westchester, the combination of humidity and fine construction dust accelerates this; we see roller failure in 7 to 10 years on doors that see daily use.
• The door lifts slightly when you pull the handle, then drops. The roller carriage has come off its adjustment screw, which means the panel is now riding on the track itself. Left alone, this gouges the aluminum track and turns a $200 roller replacement into a $500 track job.
• The lock bolt won’t fully throw into the strike plate. Over time, the door settles, or the rollers wear unevenly, and the panel drops a quarter inch. The lock still looks fine, but it’s not engaging like it did. On an impact door, that’s the difference between a sealed unit and a weak point in a storm.
• Water staining on the interior floor at the track corners. The weep holes in the bottom track are clogged, or the weatherstripping has compressed to the point where driving rain pushes past it. In Westchester, where afternoon storms come sideways, this shows up fast.
• You feel more heat or humidity near the closed door. The interlock weatherstripping between the fixed panel and sliding panel has lost its compression. This door was engineered as a thermal break; when the seal dies, your AC works harder in the hottest months.

Replacement Cost & What’s Included

In Westchester, expect a full roller replacement on a CGI slider to run $180 to $340 per panel including parts and labor, a new handle-and-lock set $150 to $280, and a track replacement or repair $350 to $620 depending on whether the bottom track needs to be cut out and a new extrusion set. The spread comes down to the series: 9600-series hardware is heavier and costs more, and doors wider than 6 feet require two technicians to safely lift and reset the panel. Every quote is a written line item; you’ll see the part cost and the labor separated, and the price we sign off on is the price you pay with no change orders added later. We stand behind the parts and the workmanship, and if something isn’t right, the Done Right Promise means we come back and make it right.

DIY or Call Us?

The honest answer: you can safely check a few things on your own, but past that, call us. You can vacuum the bottom track, clear the weep holes with a pipe cleaner, and tighten the visible screws on the handle. What you should not do is pull the sliding panel off the track. A 6-foot CGI impact panel weighs 180 to 250 pounds, and if it tips while you’re working on the rollers, you’re looking at a crushed foot, a shattered panel, or both. The most common DIY failure we repair in Westchester comes from a homeowner who got the panel off, replaced the rollers, and couldn’t get the panel back onto the adjustment screws, leaving the door hanging out of square. If you’re unsure, call us at (850) 721-1218. We’ll tell you over the phone whether it’s worth a service call or whether we can walk you through a cleaner fix.
