CGI Sliding & Patio Doors: The Boca Raton Owner’s Guide

CGI sliding and patio door replacement in Boca Raton typically runs $2,400 to $4,800 installed, depending on glass package, frame finish, and whether you need a standard 2-panel slider or a multi-panel configuration. We stock the most common CGI rollers, tracks, handles, and lock assemblies on our trucks, and in most cases we can have the full door unit here within 3 to 5 business days once we confirm your measurements. Most homeowners discover the problem the same way: the door that once glided with two fingers now takes a shoulder, or the lock no longer catches cleanly, or there’s a hairline crack you found while cleaning the glass and now can’t unsee.

Which CGI Models This Applies To

CGI builds their sliding and patio doors across several series lines, and we regularly work on all of them in Boca Raton. The main families we see are the Estate Collection, the Sentinel series, and the classic 900 Series. Each series uses different roller assemblies and interlock profiles, which is where a lot of well-meaning parts ordering goes sideways. A roller that fits a 2005 Sentinel won’t necessarily fit a 2018 Estate door, even if both panels are 80 inches tall. If you open your door and look at the top corner of the operating panel, you’ll usually find a CGI label with the series name and sometimes a 4- or 5-digit product code. That code is the single fastest way to confirm which roller, lock, or replacement panel you need. As an independent service provider, we’re not affiliated with CGI corporate, but we have been installing and repairing their doors across South Florida for years, and we source both OEM CGI parts and quality aftermarket equivalents when they’re genuinely comparable. For hardware like rollers and locks, OEM is almost always worth the few extra dollars. For rollers, specifically, we stock a stainless-steel upgrade option that holds up far better than the nylon wheels some older units shipped with.

Signs Your CGI Sliding & Patio Doors Is Failing

• You have to lift or “lift and slide” the panel to get it moving. That’s the roller assembly flattening out or the track wearing unevenly. In Boca Raton’s humidity, steel rollers corrode from the inside out, and the bearing seizes long before the wheel looks bad.
• The door sounds like it’s dragging gravel. Grit and sand from beachside air work into the track and chew up the roller face. Once the roller gets flat spots, every pass grinds them deeper.
• The lock lever goes up and down but the hook won’t reach the keeper. Over years, the interlock wears, or the panel sags slightly as rollers break down. The door “looks” locked but a firm shove at the interlock shows daylight between the panels.
• You see condensation or fogging between the glass panes. The insulating glass unit’s perimeter seal has failed. Once moisture is in, the argon or krypton gas fill is gone and the glass is doing far less work against Boca Raton heat.
• Water stains on the interior floor, even after light rain. The bottom track’s weep system is clogged or the roller height is so far out of adjustment that the interlock no longer sheds water. Left alone, this rots the subfloor under the track.

Replacement Cost & What’s Included

We give every Boca Raton homeowner a written line-item quote before any work begins. For CGI sliders, a standard 2-panel replacement door with clear impact glass starts in the $2,400 to $3,200 range. Add tinted or low-E glass, a custom frame color, or a 3-panel configuration and you’re looking at $3,500 to $4,800. The biggest cost wildcard isn’t hardware, it’s glass package. Impact-rated laminated glass is mandatory in most of Boca Raton and the price difference between clear and energy-efficient tinted is real but pays back in AC load. Every quote includes the door, new rollers and track if needed, removal and haul-away of the old unit, all fasteners, sealants, flashing, and interior trim work. There are no change orders, period. Our workmanship warranty stands behind every install, and the 36500-Day Done Right Promise means if we didn’t get it right, we come back and make it right.

DIY or Call Us?

There are two things you can safely do yourself: clean the track with a dry brush and inspect the door label so you know your series and product code. Everything beyond that, especially on a CGI impact-rated unit, involves real risk. The panels on these doors are heavy, regularly 150 to 250 pounds each. When a roller finally gives way and the panel drops out of the track, it doesn’t fall gracefully; it twists, and it takes the interlock and often the frame with it. We also can’t overstate this: the force needed to reposition a warped panel or seat a new roller can shatter the glass if the frame is out of square. That’s not a scare tactic. We’ve watched neighbors try, and we’ve cleaned up the result more than once. If your door is dragging, rattling, or not locking tight, call us at (561) 816-5648. We’ll diagnose it, give you exact numbers, and only replace what actually failed.
