CGI Windows & Doors Service Nationwide | Winslow Windows & Doors

Why Naples Homeowners Choose CGI Windows & Doors

We provide CGI in Naples - independent windows and doors service from Old Naples bungalows to the glass-walled estates in Port Royal and Pelican Bay. Our techs have rebuilt enough CGI Estate Impact and Targa Series units along the Gulfshore to know these products down to the extrusion profiles, and we service even discontinued lines that manufacturer-authorized channels won’t touch. As an independent CGI service provider, we’re not tied to one brand’s sales quotas - our only job is keeping your existing CGI windows and doors watertight, square, and code-compliant. Call (239) 899-6411 for a straight answer and an honest fix.

CGI holds a particular place in Collier County. The company built its reputation in South Florida, and Naples homes carry more CGI products than nearly any market outside Miami-Dade and Broward. The reason is straightforward: CGI was one of the first Florida manufacturers to engineer its entire line around Miami-Dade’s High Velocity Hurricane Zone standards, which happen to exceed what Collier County’s wind-borne debris region requires. A CGI window rated for a 170 mph design pressure in Bal Harbour is overbuilt for a home off Gulf Shore Boulevard. That over-engineering matters here, because Naples sits in a 160+ mph design wind speed zone with salt air that punishes lesser materials. Homeowners who bought CGI twenty years ago, when the Estate Impact line first appeared in Old Naples, often still have windows performing well today - but time and salt work on everything eventually.

Why Trust Winslow Windows & Doors for Your CGI Windows & Doors?

Ed Winslow grew up in Miami and learned the windows and doors trade at Miami Dade College’s construction technology program, then spent decades in the field before founding Winslow Windows & Doors in 2011. He’s been installing Impact Windows services on everything from quiet Naples ranch homes to high-rises overlooking the Gulf along Vanderbilt Beach Road for well over a decade. Ed still shows up to every job site at least once - not to supervise, but because he genuinely wants to see how the light comes through a finished window. My name’s on the truck. That means I stand behind every frame we set.

Our technicians work on CGI products weekly, not occasionally. That repetition breeds familiarity with the specific failure patterns these units develop in Naples - the corrosion points on Estate Impact double hungs, the roller wear on Targa sliders, the glazing bead fatigue that appears after repeated storm-pressure cycles. We carry the hardware, balances, and weatherstripping profiles these repairs demand, and we machine compatible stainless steel components when a CGI part has been discontinued. Every job carries the 36500-Day Done Right Promise: if it’s not done right, we make it right. A century-long standard of accountability, because Ed’s name is on the door - and on every job we do.

We answer the phone with a live person, 24 hours a day. When a Naples homeowner calls about a CGI window that won’t close before a storm front moves in, they talk to a person who knows what a CGI Estate Impact is - not a call center reading from a script.

Common CGI Windows & Doors Problems We Fix in Naples

• Cracked or loosened glazing bead on aging Estate Impact units. The vinyl glazing bead that holds CGI’s laminated glass in the sash frame takes a beating from repeated pressure cycles during hurricane season. After enough storm-driven flex, the bead develops hairline cracks or loses its grip. We’ve seen this on Estate Impact windows installed in the mid-2000s throughout Old Naples and Pelican Bay. Left untreated, the glass shifts slightly and water finds its way into the frame. We replace the bead with new material and re-seat the glass properly.
• Corroded or seized balance springs in double hung windows. Salt-laden Gulf air is relentless on metal components, especially within two miles of the water. CGI double hung windows use a balance system that originally shipped with steel components. Years of salt exposure cause corrosion that makes the upper sash hard to raise or impossible to hold open. This is the single most common CGI repair call we get from beachfront condos along Gulf Shore Boulevard and homes in the Moorings. We replace the balances with marine-grade stainless steel assemblies that hold up far longer than the originals.
• Warped or misaligned sash frames on south-facing windows. Naples sun is brutal, and south-facing CGI windows spend all day baking. The vinyl on older CGI Classic Impact and Estate units can warp slightly under prolonged heat exposure, which misaligns the sash and creates gaps where air and water intrude. We straighten what’s salvageable and replace what isn’t, then re-align the sashes so the window locks tight again.
• Worn or torn weatherstripping on Targa Series sliding doors. The Targa Series uses a specific weatherstripping profile along the interlock and jambs. After years of sliding open and closed, plus salt air and heat, that stripping compresses, tears, or peels away. Homeowners notice wind whistle on breezy days and water seepage during the rainy season’s intense downpours. We replace the stripping with the correct profile, which eliminates the draft and stops the leak.
• Fogged glass from seal failure. CGI impact windows are built as a laminated glass unit with an insulating air space. When the seal around that air space fails - often from years of thermal cycling in the Naples heat - moisture works its way between the panes and fogs the glass. The impact protection remains intact, but the view through a $5,000 picture window over a Grey Oaks golf course fairway is ruined. We replace the insulating glass unit and restore the clarity.

CGI Parts & Our Repair-vs-Replace Approach

CGI still supplies hardware for its current product lines, and we stock the common items locally so most Naples repairs don’t wait on a freight truck. Balances, rollers, weatherstripping, sash locks, and glazing bead for Estate Impact and Targa Series units sit on our service vehicles. When a CGI line has been discontinued and the manufacturer’s parts warehouse runs dry, we machine compatible replacements from high-grade stainless steel - measured against the original component’s exact dimensions, not a generic approximation.

Our repair-versus-replace decision comes down to frame integrity. If the aluminum or vinyl frame is sound, we repair the moving parts and seals and the window returns to service for a fraction of replacement cost. If salt corrosion has eaten through the frame itself, or if impact damage compromised the structural channel that holds the glass, we tell you straight: this unit needs replacement. We’ll never sell a repair that won’t hold, and we’ll never prescribe a replacement when a $200 balance assembly fixes the problem. Call (239) 899-6411 for an honest assessment.

Our CGI Service Process - Step by Step

1. 1
   Diagnosis. We inspect the window or door in place, test the operation, check the glazing and weatherstripping, and identify the exact failure point. For CGI units specifically, we look for the failure patterns known to that product line - corrosion on Estate Impact balances, glazing bead fatigue from pressure cycles, or Targa roller wear.
2. 2
   Repair or replacement recommendation. We explain what we found, what it costs, and how long the fix will last. No pressure, no upsell. If a repair makes sense, we quote the repair. If replacement is the honest answer, we explain why in terms you can verify.
3. 3
   The work. We arrive with the parts, background-checked and in uniform. For balance replacements, we remove the sash, extract the old corroded assembly, install marine-grade stainless steel, re-grease the tracks, and re-hang the sash. For weatherstripping, we remove every trace of the old material and bed the new profile correctly.
4. 4
   Testing. Every window gets operated through its full range after the repair. We check that the sash glides, the locks engage, the weatherstripping seals, and no light passes where it shouldn’t. After a repair, we water-test critical areas in West Naples and coastal corridor homes before we call the job done.
5. 5
   Warranty. Our workmanship carries the 36500-Day Done Right Promise. If something’s not right, we come back and make it right. That’s not a tagline. It’s Ed Winslow’s name on the invoice.

CGI Products We Service & Install in Naples

We service and install the full CGI lineup that Naples homeowners actually have in their homes: the Estate Collection and Estate Impact series, the Classic Impact line found in many 1990s and early-2000s Naples builds, and the Targa Series sliding glass doors common in lanai-facing rooms throughout Pelican Bay, Grey Oaks, and CGI repair in Bonita Springs and Old Naples. We stock balances, rollers, weatherstripping, and hardware for these lines locally. When a discontinued component can’t be sourced from CGI, we machine a stainless steel replacement to the original spec. On a 2007 CGI Estate Impact double hung in Old Naples, our tech found the upper sash wouldn’t stay up - the original balance system had corroded through from years of salt air. We replaced both balances with marine-grade stainless steel assemblies, re-greased the tracks, and reinstalled new glazing bead. The window now glides smoothly and seals tight. That’s what CGI-specific expertise in Naples looks like.
