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

CGI sliding and patio door parts replacement in Palm Beach typically runs $180 to $680 depending on the part - rollers, handles, locks, or weatherstripping - with full panel replacement starting around $1,900 installed. We stock the common CGI rollers, tandem assemblies, and latch hardware on our trucks, so most Palm Beach calls are same-day fixes. What usually brings a homeowner to this page is a door that suddenly drags, won’t latch, or whistles during an afternoon squall off the Intracoastal. By the time you’re reading this, you’ve probably already dealt with the door jumping its track or a handle that spins without engaging. Here’s exactly what to do about it.

Which CGI Models This Applies To

CGI’s sliding door lines break into two main families. The Estate Series and Tribute Series are the most common in Palm Beach, especially along the waterfront where impact-rated assemblies are code-mandated. Both use a stainless-steel roller carriage that sits inside an aluminum track, but the carriage dimensions differ between series - an Estate roller will not seat correctly in a Tribute track, and forcing it scores the rail. The quickest way to identify what you have is the product label on the interior side of the door panel’s vertical stile. It lists the series name, the Miami-Dade NOA number, and the panel size. If the label’s faded from years of salt air, measure the door panel thickness: Estate panels run 1-3/4 inches thick, Tribute panels run 2 inches. The stack weight matters too. A three-panel Estate sliding setup can exceed 700 pounds, which is why the tandem roller assemblies on those units wear faster than anything else. On the OEM-versus-aftermarket question: for rollers and locks, we’ve had solid results with OEM-style replacements that match the original spec exactly. For impact glass panels themselves, we only install genuine CGI - substituting unrated glass on an impact-rated door is a code violation in Palm Beach and defeats the entire point of the assembly.

Signs Your CGI Sliding & Patio Doors Is Failing

• The door drags or takes two hands to move. This is almost always the roller carriages. In Palm Beach, salt air and windblown sand from the beach side get into the track, score the nylon roller wheels, and eventually flatten one side so the door rides rough. You’ll hear it too - a grinding sound when the door slides.
• The handle turns but the latch doesn’t move. CGI’s mortise latch uses a gear-driven mechanism inside the door panel. Over time the internal gears strip - especially on doors that get heavy daily use in a screened lanai - and the handle spins free. This is a common Palm Beach failure because patio doors here are the main entry, not an occasional architectural feature.
• The door won’t stay locked, or the lock feels loose. The strike plate and keeper on the jamb side can work loose from thousands of open-close cycles. On impact-rated CGI doors, a loose lock also means the interlocking rails aren’t engaging at the meeting stile, which weakens the whole assembly during wind-load pressure.
• Water stains or dampness on the interior floor near the track. The weatherstripping along the bottom of a CGI door is a sacrificial part. Florida UV breaks it down, it compresses, and then afternoon thunderstorms push water under the panel. Once water sits in the track, the rollers corrode even faster.
• The door jumps off the track or tips when opened halfway. This is a failure of the anti-lift blocks or the roller itself breaking free of its housing. It’s also the point where DIY stops being safe - a 300-pound glass panel leaning out of its track can cause serious injury if you’re trying to reseat it alone.

Replacement Cost & What’s Included

Here are the installed price ranges we quote most often in Palm Beach:

• Single roller carriage replacement: $180 to $260 per panel, including the roller, track cleaning, and alignment.
• Both tandem roller assemblies on a heavy Estate panel: $325 to $425.
• Handle and mortise latch replacement: $140 to $220 depending on the finish and series.
• Full-length bottom weatherstripping and track reseal: $120 to $195.
• Complete door panel replacement (impact glass, CGI genuine): starts around $1,900 and goes up based on panel width, glass package, and whether the frame needs rework.

What drives the range is the series - Estate parts cost more than Tribute - and whether the track itself is worn to the point of needing replacement. We quote the parts and the labor as separate line items, so you see exactly what you’re paying for. No change orders, no surprise add-ons. Every parts repair includes the $40-off-any-repair-over-$200 standing discount, which applies automatically. And every job we do carries the 36500-Day Done Right Promise: if it’s not right, we come back and make it right. That’s been Ed Winslow’s rule since 2011, and it’s not changing.

DIY or Call Us?

Some things you can safely handle. Cleaning the track with a stiff brush and a shop vac, lubricating the track with a dry silicone spray, and visually checking for obvious damage to the weatherstripping - all fair game, all cheap. What you shouldn’t attempt is lifting an impact-rated door panel off its track to swap rollers. CGI panels are heavy, and when one decides to tip, it happens fast. We’ve pulled homeowners out of that exact situation more times than we can count, and it’s rarely just the roller that needs replacing by then - it’s usually a bent frame or a chipped glass corner from the panel going down. If you’re not sure whether the problem is the roller or the track itself, call us at (561) 831-7863. We’ll tell you over the phone what to look for, and if you need us on site, there’s no trip charge inside our home county.
