AfterCGI Sliding Glass & Patio Doors in Naples: What to Know First
We service, repair, and replace CGI sliding glass and patio doors throughout Naples as an independent CGI service provider. Most sliding door repairs run one to two hours on site, and full replacements are typically quoted within two business days of measuring. Pricing is honest and line-itemed before we start, which means the number you see is the number you pay. If you own a CGI door that is binding, leaking, fogging, or simply tired after fifteen or twenty years of salt air, call (239) 326-9942 and we will schedule a time to look at it properly.
How CGI Products Fail - and How We Fix Them
CGI builds a serious door. The extruded aluminum frames and laminated impact glass hold up against storms that would flatten lesser products. But no door is immune to Southwest Florida, and after years of service along the Gulf, certain patterns show up in Naples homes. Here is what we see most often.
- Roller failure on the Estate Collection sliders. The Estate line uses heavy laminated glass panels that can exceed 200 pounds per panel. The factory rollers are serviceable, but once the internal bearings wear flat from sand and salt intrusion, the panel grinds instead of glides. Homeowners mistake it for a bent track. It is almost always the rollers. We replace them with stainless-sealed aftermarket rollers sized to the panel weight, not the generic hardware store version.
- Weep-hole blockage leading to interior water staining. CGI frames are designed to channel water through weep holes at the sill. In Naples, wind-driven rain carries fine salt spray and debris that hardens into a crust inside those channels. The door does not leak because the glass failed. It leaks because the water has nowhere to drain. We clear the weep system fully, not just the visible opening, and verify drainage with a measured water test before we call the job done.
- Sun-baked polypropylene pile and weatherstripping on older CGI doors. Older CGI sliding doors, particularly pre-2010 models, used pile weatherstripping that flattens and crumbles after a decade of southwest exposure. The result is a door that whistles in summer storms and lets humidity bleed into the house. We reglaze the weather-seal channels with silicone-bulb or fin-seal material matched to the frame profile. This is not a cosmetic fix. It changes how the door performs in a hurricane.
- Lock-stile misalignment on doors that have settled. Concrete slabs in Naples move. When the slab settles even a quarter inch, the lock stile drops and the multi-point lock will not engage without lifting the panel. Some contractors will grind the keepers until they catch. We re-square the panel, adjust the rollers at both ends, and set the keepers so the lock works with one hand and the door seals evenly across the full height. Grinding is a temporary band-aid. Re-squaring is a repair.
- Fogged or failed insulated glass units. Many CGI sliding doors in Naples are approaching the age where the argon fill has dissipated and the seals have begun to fail. You will notice it first as a haze you cannot wipe off, then as trapped moisture between the lites. We replace the IGU directly with glass matched to CGI’s original lamination and tint specifications. The frame stays. The warranty paperwork is handled correctly so the replacement is documented.
Our CGI Sliding Glass & Patio Doors Process
Every CGI job follows the same order of work. No surprises, no skipped steps.
- 1
Call and describe the symptom. A live person answers, 24 hours a day. Tell us what the door is doing. Binding, leaking, fogging, rattling, locking hard. We will ask a few questions and schedule the diagnostic.
- 2
We measure and diagnose. A background-checked, uniformed technician arrives and measures the opening, the panel weight, the roller condition, the track, the seals, and the square of the frame. We read the opening carefully, the way Dale Kessler taught every one of our techs.
- 3
We quote on paper before work begins. You get side-by-side pricing for OEM CGI parts and quality aftermarket equivalents where they exist. We tell you what each option buys you. You decide. We do not start until you have signed off.
- 4
We make the repair or replacement. The rollers, seals, hardware, or IGU are installed to manufacturer specifications. Everything is shimmed, squared, and torqued correctly.
- 5
We test, clean, and document. The door is cycled repeatedly, the locks are checked, drainage is verified. The area is left cleaner than we found it. Warranty layers are registered in writing before the truck leaves the driveway.

Why Naples Homeowners Call TruePane Windows & Doors for CGI Work
We have been serving local communities for over 42 years, and Dale Kessler founded TruePane in 2008 on a simple rule that still governs every install: if the pane is not true, the job is not done. The 90-Day Done Right Promise means if it is not right when we leave, we come back until it is. No paperwork fights, no arguing. The Keystone Standard gets both manufacturer warranty layers registered in writing, with durations stated, before the truck is back on the road. And because we are an authorized installer for more than a dozen lines including PGT, CWS, ES Windows, and ECO Window Systems, we can talk you through your options without pushing a single brand. If it is not right when we leave, we come back until it is. That is not a slogan. That is the job.
FAQs
CGI’s warranty coverage depends on the product line, the original installation date, and whether the original installer transferred everything correctly. Yes, we can review your paperwork and confirm what is covered. We register every replacement part and IGU in writing so the warranty trail stays intact for anything we touch.
Common rollers, handles, and weatherstripping are on our trucks or available within two to four business days. Custom IGUs matched to CGI’s lamination and tint generally take two to three weeks because they are built to spec, not pulled from a shelf. If your door is unsafe or unsecured, we will make it safe at the diagnostic visit.
If the frame is square, the glass is clear, and the failure is a roller, seal, or lock, repair is usually the right call and far less expensive. If the frame is corroded through, the glass has failed in multiple lites, or the door no longer meets current code, replacement makes more sense. We will show you the math both ways before you commit, with a free estimate at (239) 326-9942.
We quote both side by side on paper. OEM CGI parts carry the fullest warranty continuity. Quality aftermarket parts, like sealed stainless rollers or upgraded silicone weatherstripping, can outperform the original in Naples conditions and often cost less. You choose. We install either to the same standard.
Yes. Full replacements in Collier County require permitting and inspection. We pull the permit, schedule the inspection, and stand behind the work until it passes. Repairs and parts replacement typically do not require a permit.
