CGI Windows & Doors in Clewiston, FL | TruePane Windows & Doors
We provide independent CGI in South Bay and throughout Clewiston, from single-sash rebuilds to full insert replacements. The one thing that separates our CGI work here from anywhere else: we account for the sugarcane ash that settles into frame tracks and weep holes after every harvest burn, then hardens into a paste when Lake Okeechobee’s morning fog rolls through. That failure pattern shows up on nearly every older CGI window in town, and most repair crews never look for it. Call (813) 320-9346 for a free estimate on CGI service in Clewiston.
Why Clewiston Residents Choose Us for CGI Service
Our crews have been retrofitting CGI impact windows and doors into Hendry County’s Wind-Borne Debris Region for over a decade. We know how CGI’s aluminum-frame profiles, mullion systems, and stainless-hinge hardware perform under Clewiston’s ash-and-humidity exposure because we see it weekly, not occasionally. Dale Kessler, our owner, grew up around building maintenance work and learned early that a callback means the first job wasn’t finished. That’s the standard we carry into every CGI service call here: if the pane is not true, the job is not done. We order CGI products directly through factory distribution, which lets us match original frame depths, finish codes, and structural mullion loads without relying on generic supplier catalogs. For Clewiston homeowners, that means a repair that fits the opening the way the original did.
We’re not a manufacturer-authorized service center. We’re an independent CGI service provider, which matters more than most people realize: we work for the homeowner, not the warranty department. We troubleshoot honestly, spec factory-original parts where they matter most, and tell you plainly when a rebuild beats a replacement. Learn more about our CGI sales & service.
Common CGI Windows & Doors Problems We Solve in Clewiston
- Ash-clogged weep holes on CGI 3000 Series single-hungs. After each sugarcane burn, fine black ash settles into the bottom track and blocks the drainage path. Water sits inside the sash, softens the seal around the glass, and corrodes the balance shoe. We clear, sleeve, and often enlarge the weep holes with stainless inserts so they don’t clog again next season.
- Cloudy glass and failed seals on CGI Classic Series fixed picture windows. Lake Okeechobee’s persistent humidity degrades silicone setting blocks and gaskets faster than in coastal towns to the east. Internal condensation shows up within 7 to 10 years on many Clewiston homes. We replace the IGU or the gasket set depending on what failed, and we tell the homeowner which one went bad before we quote anything.
- Pitted anodized bottom rails from harvest-season cane dust. Fine dust driven by open-field winds abrades the anodized finish on double-hung sashes where they contact the track. Raw aluminum starts pitting. We treat the surface, install ash-resistant pile weatherstrip, and set the sash so contact friction stays low.
- Binding casement operators on older CGI Estate Collection windows. Ash packs into the operator base and strips gear teeth when the crank is forced. If the frame extrusion is straight and the interlock isn’t split, we rebuild the hardware in place rather than sell a full replacement. That typically saves the homeowner 40 to 60 percent.
- Threshold and roller failures on CGI 700 Series sliding glass doors. Morning fog off the lake keeps aluminum thresholds damp much of the year. We see pitting and roller degradation earlier here than in Fort Myers or LaBelle. We spec marine-grade replacement rollers and reset the threshold for proper drainage.
CGI Service in Clewiston: What Local Conditions Mean for Your Equipment
After every sugarcane harvest burn, the fine carbonized ash settles into CGI window weep holes and door tracks along Clewiston’s US Sugar company streets. Unlike our CGI in Belle Glade ten miles north, the ash here mixes with Lake Okeechobee’s morning fog to create a sticky paste that hardens in the track. That paste is the real killer. It blocks drainage, traps water inside the frame, and accelerates the breakdown of every soft component from weatherstripping to balance bearings. Our techs never see this in Fort Myers or LaBelle, and a crew from out of town won’t spot it until the window is already failing. On a 1960s ranch along Sugarland Boulevard just east of the mill, our tech pulled a CGI 3000 Series single-hung whose bottom sash had seized after harvest-season ash packed the left jamb track. The weep holes were completely blocked, and water had been trapped inside the frame for months, corroding the zinc-plated balance shoe. We replaced the balance assembly with a marine-grade aftermarket shoe, drilled and sleeved enlarged weep holes with stainless inserts, then reset the sash with new ash-resistant pile weatherstrip. The homeowner scheduled the matching second window the same day. That is what Clewiston-specific service looks like: knowing where the ash goes, what it does once it’s there, and how to stop it from happening again. If it needs to be in writing to be true, we will put it in writing.
CGI Models & Products We Service in Clewiston
We service the full CGI product line sold across Hendry County, including the 3000 Series single-hung impact windows, Estate Collection casement and awning windows, 700 Series impact sliding glass doors, and Classic Series fixed and picture windows. For structural components like mullions, corner keys, and hinge bases, we use factory-original CGI replacement kits. Those parts carry load and must match the extrusion profile exactly. For wear items, we make a different call: sash bushings, weatherstripping, and weep covers often get marine-grade aftermarket parts that outlast OEM under Clewiston’s ash-and-humidity condition. We stock common CGI service parts locally for faster turnaround, so a repair doesn’t stall waiting on a truck from the coast. This page is the only place that maps Clewiston’s sugarcane-ash and Lake Okeechobee micro-humidity directly onto CGI frame parts, weep drainage, and hardware specs. A generic impact window quote doesn’t account for any of it. Our estimate does.
CGI Service Pricing in Clewiston
CGI service pricing in Clewiston depends on what failed and how far it went before you called. A sash rebuild with new balance assemblies and weatherstripping usually runs less than half the cost of a full replacement. A glass package replacement on a fixed picture window sits in the middle. A full insert replacement for an original jalousie or single-pane aluminum frame runs higher, but that’s a full upgrade, not a patch. The honest replace-vs-repair rule we follow: unless the frame extrusion is bent or the interlock is split, we rebuild the sash and hardware in place. That typically saves 40 to 60 percent versus replacing the unit. Every estimate includes a written line-item quote with both warranty layers stated up front, so you see exactly what you’re paying for and what’s covered. Call (813) 320-9346 for an exact quote on your CGI windows or doors. Estimates are free, and nobody will pressure you into a replacement you don’t need.

FAQs - CGI Windows & Doors in Clewiston
The ash itself doesn’t break the glass. It blocks the weep holes in the frame’s bottom track, which traps water inside the sash channel. That standing water softens the sealant around the glass, corrodes the zinc-plated hardware, and eventually leads to cloudy panes, seized sashes, and frame pitting. On a CGI 3000 Series, the failure usually shows up first as a window that’s harder to open after October. The fix is drainage restoration plus resetting the affected parts. Call (813) 320-9346 and we’ll inspect yours before the next burn season.
Because those are harvest months. Fine cane ash and dust get worked into the jamb tracks every day, and the morning fog off the lake turns it into a sticky film that hardens as it dries. By late season, the sash is riding on packed debris. We clean the tracks, replace the balance assemblies if they’ve been stressed, and install ash-resistant pile weatherstrip so the next season doesn’t seize it again. Call (813) 320-9346 for a free estimate and we’ll take a look.
Sometimes. If the frame extrusion is straight, the interlock is intact, and the original frame was installed to current anchoring standards, we can often replace the impact glass package and reseal the unit to meet Hendry County’s Wind-Borne Debris Region requirements. If the frame is bent, pitted through, or was never anchored to code, a full insert replacement is the honest call. We’ll measure it twice and tell you plainly which applies to your windows.
For south-facing CGI 700 Series doors near the lake, we recommend a marine-grade anodized aluminum threshold with integrated drainage channels rather than an OEM replacement. The persistent morning fog and humidity pit standard thresholds faster here, and the marine-grade material holds up longer than factory finish under Clewiston conditions. The roller assemblies should also be spec’d for wet exposure. Call (813) 320-9346 for a written quote on the full threshold and roller job.
No, the permit process is the same Florida Building Code pathway, but Clewiston sits in Hendry County’s Wind-Borne Debris Region, so the product approval numbers and anchoring schedules must match that designation. Fort Myers and Cape Coral are in Lee County with their own local amendments, but the underlying impact requirement is similar for all three. We pull permits on every CGI job in Clewiston and handle the inspections, so the paperwork doesn’t become your problem.
