CGI Sliding Glass & Patio Doors in Palm Beach: What to Know First
We provide independent CGI sliding glass and patio door repair and replacement across Palm Beach, with most diagnostic visits booked within 48 hours and most parts sourced within a week. Our pricing is upfront and itemized: you’ll see the parts cost, the labor cost, and the total before we touch anything. If you own a CGI slider that’s dragging, leaking, or locking poorly, call (561) 782-7525 and we’ll have a technician who actually knows these doors take a look.

This page is written for Palm Beach homeowners who already own CGI products and need someone who understands how they’re built, how they fail, and what makes them worth fixing rather than swapping. My name is Ed Winslow, and we’ve been doing this work in Palm Beach since 2011. The one down the road.
How CGI Products Fail - and How We Fix Them
CGI builds a serious impact door. We install them, we repair them, and we’ve seen the same failure patterns repeat across hundreds of Palm Beach homes. Here’s what we run into most often:
- Roller collapse on Estate Collection sliders. The Estate series uses a two-roller carriage per panel, and when the lower track gets sand and salt grit in it, the rollers grind down fast. Homeowners report the door going from smooth to “feels like pushing a truck” in a single season. The real cause is usually track debris chewing the nylon bearings, not the rollers themselves. We clean the track channel, check roller wear, and replace only what’s actually failed. Palm Beach’s salt air accelerates this faster than inland communities see.
- Lock strike misalignment on stationary panels. CGI’s multi-point locks are strong, but the strike plates on fixed panels shift when the frame settles in concrete slab homes. You’ll feel the handle turn halfway and jam. We realign the panel, shim the strike, and verify the lock engages all points before we leave.
- Weep hole clogging along the bottom track. Summer downpours expose this quickly. CGI tracks are designed to drain, but fine Palm Beach sand, pollen, and mulch dust plug the weep channels. Water backs up, then runs under the frame. Our fix is mechanical clearing plus a check that the interior weather seal hasn’t wicked water into the track cavity.
- Fogged glass units on older CGI sliders. If your door is from the pre-2015 era, you may have a failed insulating glass unit showing condensation between panes. CGI’s warranty terms on glass vary by purchase date, and we always check the door’s marking before quoting. When replacement glass is the right call, we match the impact rating and tint so the door still performs the way it was specified.
- Drag from interlock gaskets on the 8400 series. The interlock between the active and fixed panel relies on a felt-fit gasket that stiffens with age. Homeowners assume the rollers are shot, but the panel is actually catching on its own weather pile. We reset the interlock clearance and replace the gasket rather than selling a roller job that won’t fix the drag.
Our CGI Sliding Glass & Patio Doors Process
- 1
Call and diagnosis. You call (561) 782-7525, a live person answers, and we schedule a Palm Beach site visit at a time that works. Our tech arrives in uniform, background-checked, and starts by seeing the door operate.
- 2
Evidence-based inspection. We examine the track wear pattern, panel plumb, lock engagement, and glass seal condition. On CGI doors, we check both the visible hardware and the concealed roller carriages before quoting anything.
- 3
Parts decision. Where OEM parts are still available and priced reasonably, we use them. Where CGI part lead times run long or the aftermarket option is genuinely better, we tell you plainly and let you decide. No mystery parts on the invoice.
- 4
The repair or install. We complete the work with the panel removed safely, the track cleaned, and all seals reset. If it’s a replacement door, we set the frame plumb and square before hanging the panel.
- 5
Test and verify. We run the door through full travel at least ten times, confirm lock engagement and seal compression, and check drainage with water where the frame allows.
- 6
The guarantee. Every job leaves with our Done Right Promise. If it’s not done right, we come back and make it right. That’s not a warranty card; that’s how we’ve operated since 2011.

The price moves based on panel size, track condition, whether we’re reusing existing framing, and whether the door needs re-leveling on a shifted slab. We give you a written line-item quote before any work begins, and we don’t change the number once the job starts. The $40 off any repair over $200 applies to CGI slider work, and we offer a free second opinion on any written estimate from another company. Call (561) 782-7525 for a free estimate.
Why Palm Beach Homeowners Call Winslow Windows & Doors for CGI Work
Because CGI doors don’t all fail the same way, and the guy who answered the phone shouldn’t need fifteen minutes to figure out what model you’re talking about. We’ve installed and repaired CGI products in Palm Beach long enough to know the failure patterns by heart. And as an independent CGI service provider, we’re not tied to a corporate service script. We tell you what the door actually needs, even when the answer is “this one’s worth saving.” If a door is beyond economical repair, we’ll say so and show you the numbers.

Our techs are background-checked and show up in uniform. Ed’s name is on the truck, and the Done Right Promise means you’re not chasing us after the job. If it’s not right, we come back. We also work on the other major impact brands in the area: PGT, CWS, ES Windows, and ECO Window Systems. So if you have a mix of brands across your home, one call covers the doors and windows together.
FAQs
A proper repair using the correct parts and methods will not void your CGI warranty, but a hack job that damages the frame or uses incompatible hardware can. That’s why we match parts to the door’s model and impact rating, and document every job with photos. If you’re under warranty, we’ll always check the eligibility first before quoting any paid repair. Call (561) 782-7525 and we’ll walk you through it.
Most roller, track, lock, and gasket repairs are completed in a single visit of two to four hours. Full glass unit replacements depend on the glazing lead time, which typically runs one to three weeks for impact-rated CGI units in Palm Beach. We’ll give you a real timeline before you commit.
If the frame is square, the glass is intact, and the failure is in hardware or seals, repair is usually the right call and costs a fraction of replacement. We recommend replacement when the frame has corroded, the slab has shifted the structure, or the glass unit has failed and the door is over fifteen years old. We’ll show you both numbers and let you decide with no pressure.
Yes. When replacing a glass unit in a CGI door, we order the glazing to match the original tint, thickness, and impact certification. That means the door still performs and looks consistent with its neighbor panels. Matching the glass spec is standard on every CGI glass replacement we do in Palm Beach.
We’ll always work to get a Palm Beach CGI repair scheduled as quickly as our current workload allows, and we’ll tell you the real date upfront, not a vague “soon.” If your door won’t close or lock, call (561) 782-7525 and we’ll prioritize getting you secure.
