CGI Sliding Glass & Patio Doors in Palm Beach: What to Know First
CGI sliding glass and patio doors in Palm Beach are among the most storm-tested impact doors you can own, and we service them as an independent CGI service provider. Most sliding door repairs on CGI units in our area run between $200 and $1,200 depending on whether you’re dealing with rollers, tracks, handles, or a full panel replacement. We quote upfront pricing before any work begins, and we typically complete sliding door repairs in one visit.
This page is for Palm Beach homeowners who already own CGI doors, or are considering them, and need a straight answer on how to keep them operating the way they should. We’re Winslow Windows & Doors, and we’ve been working on impact-rated doors in this part of Florida long enough to know exactly what salt air, humidity, and storm season do to them. If you’ve got a CGI slider that’s sticking, dragging, or not locking cleanly, call (561) 831-7863 and a real person answers.
How CGI Products Fail - and How We Fix Them
- Roller fatigue on CGI Estate Collection sliders. The Estate Series uses heavy interlocking panels that weigh more than standard sliders. Over time, the factory rollers flatten slightly, and the door starts dragging on the bottom track. We see this on doors facing direct sun exposure, where the added heat accelerates roller wear. We replace the rollers with OEM-spec parts and re-balance the panel, which restores the original glide. Skipping this repair leads to track damage, which costs far more to fix.
- Lock misalignment on CGI Sentinel impact sliders. The Sentinel line has a multi-point locking system, and Palm Beach’s sandy soil shifts door frames over years of settlement. The lock points drift a few millimeters out of alignment, and the handle suddenly won’t throw. This is a frame adjustment issue, not a lock failure. We realign the strike points and the door locks like the day it was installed. A lot of companies just replace the handle, which fixes nothing.
- Track corrosion near the salt line. Doors within a half-mile of the Intracoastal pick up salt residue on the bottom track, and even powder-coated CGI tracks eventually show pitting if they’re not cleaned and treated. We see this constantly along the estate corridors of El Brillo Way. We remove the corrosion, restore the track surface, and apply the right protective treatment. Then we tell you exactly how often to rinse the track based on your distance from the water.
- Weep hole blockage on CGI sliding glass doors. CGI doors drain through small weep holes along the bottom track. Palm Beach’s pollen, sand, and leaf debris clog those holes, and water backs up into the track and eventually into the door frame. The fix is simple if caught early. Left alone, the frame saturates and you’re looking at frame rot or corrosion on the reinforcement. We clean the channels and verify drainage on every service call, even when you called us for something else.
- Panel sag on oversized CGI patio door configurations. We service a number of CGI doors where a single panel spans eight feet or more. Over a decade of use, the panel can sag a few millimeters, and the door starts catching at the top corner. This is almost always a hinge or roller carrier issue, not a bent panel. We correct the carrier geometry, and the panel sits square again. If a customer waits too long, the glass seal itself can fail from the constant stress.
Our CGI Sliding Glass & Patio Doors Process
- 1
You call (561) 831-7863. A live person answers, day or night. You describe the symptom. We ask a few pointed questions about the door’s age, which CGI line it is, and what you’re seeing. We also tell you upfront if there’s a trip charge, but inside our home county there isn’t one.
- 2
We diagnose by door, not by guess. Our tech arrives in uniform, background-checked, and inspects the track, rollers, lock points, weep holes, and panel alignment before touching anything. On CGI doors, we check the frame plumb too, because settlement is the root cause of half the problems we see.
- 3
You get a written, line-item quote. We tell you what’s actually wrong, what parts it needs, and what it costs. OEM parts when warranty or fit demands it. Quality aftermarket only when it’s genuinely equivalent and saves you real money. No change orders after the fact.
- 4
We do the repair. Most CGI sliding door work is done same-visit. We carry the common roller sets, handles, and hardware for the lines we see most in Palm Beach, so you’re not waiting on a second trip for common parts.
- 5
We test the door the way your warranty expects it to be tested. Panel weight, lock throw, drainage, and glass seal inspection. If anything’s off, we fix it before we leave.
- 6
You get the 36500-Day Done Right Promise. If it’s not done right, we come back and make it right. That’s the entire guarantee, and it doesn’t expire.

The free second opinion on any written estimate is always on the table, and if you have a written quote from another company, bring it. Call (561) 831-7863 and we’ll give you an exact number before any work begins.

FAQs
As an independent CGI service provider, we use OEM parts where warranty compliance or structural fit requires them, and we document every repair with the same care your warranty expects. We never alter the door’s structural or impact-rated components in a way that would void coverage. If you’re unsure what your specific CGI warranty covers, call us at (561) 831-7863 and we’ll walk through it before touching anything.
Common hardware for the CGI lines we see most in Palm Beach is on our trucks, which means most roller, handle, and lock jobs are done same-visit. For specialized parts or full panel work, it’s usually three to five business days. We’ll tell you before you spend a dime what the part timeline is, and you never pay for a part we didn’t quote.
If the frame is square and the glass seal is intact, repair is almost always the smarter money. We replace when the frame has structural damage, when the glass seal has failed, or when panel sag has stressed the glass unit itself. We’ll give you the repair number and the replacement number side by side, and let you decide. Call (561) 831-7863 for a free assessment.
No trip charge inside our home county. You pay for the work, not for the truck showing up. And if you’ve got a written estimate from another contractor, bring it. We’ll give you a free second opinion on it, no obligation.
Yes. We work on CGI sliding glass and patio doors regardless of who sold or installed them. The door doesn’t care who put it in, and neither do we. What we care about is that the door works the way a storm-rated product in Palm Beach is supposed to work.
