This page is for Naples homeowners who bought CGI impact windows, inherited them with a house, or are considering them for a replacement project. You’ll find real failure patterns, pricing honesty, and what we do differently on a CGI job. Not the brochure version.

How CGI Products Fail, and How We Fix Them

CGI builds a strong window. But after 15-plus years of working on them in Naples, we’ve learned where they show their age first. Here’s what we actually see:

• Sentinel and Estate series: roller wear and track binding. CGI’s horizontal sliders are popular in Naples condos and single-family homes alike. After years of salt air and daily use, the stainless rollers develop flat spots or the adjusters seize. The window gets harder to slide, then refuses to close fully. We replace rollers with OEM or high-grade aftermarket sets and clean, re-lubricate, and realign the track. The fix usually runs under two hours, and the window slides like it did the day it was installed.
• Targa and Estate casement windows: crank gear failure. Casement operators take a beating, especially in homes where windows face southwest and get baked after lunch. The internal worm gear in the crank strips, and the handle spins without moving the sash. Homeowners sometimes force it, which cracks the operator housing and damages the linkage. We replace the operator assembly and reseat the sash, checking lock points at all four corners, because a casement that doesn’t fully seat won’t perform to its impact rating.
• Fogging between panes on CGI impact glass. This is the failure every Naples homeowner knows. When the dual-seal around an impact glazing unit breaks down, humid Gulf air gets between the panes and condenses. You can’t dry it out from the outside, and the window loses insulation value. The proper fix is a new insulating glass unit made for that specific CGI frame, which we order to match the original glass specification. In many cases, especially on newer CGI windows, a replacement IGU costs less than half of a full window replacement and keeps your original frame in place.
• Sentinel single-hung: balance system fatigue. Single-hung windows from CGI rely on spring-loaded balance systems hidden inside the jambs. Over years of salt exposure, the springs weaken or the balance shoes crack. The sash becomes heavy, won’t stay up, or slams down. This is a safety concern if you have kids or pets, and it also means the window isn’t sealing at the meeting rail. We replace both balances at once, even if one looks fine, because paired systems that age together should be replaced together.
• Loosening of frames on CGI impact windows after hurricane season. South Florida homes flex. After a few storms, some CGI frames shift slightly in their rough openings, especially on second-story elevations or walls that carry roof thrust. The window still looks fine, but water starts seeping in during heavy rain. We pull interior trim, refasten the frame to the rough opening with the right fasteners at the right spacing, re-seal the perimeter with polyurethane sealant, and reset the interior trim. The fix holds, because the problem wasn’t the window, it was how the window was locked into the wall.

Our CGI Impact Windows Process

Here’s what a typical CGI service call looks like with Winslow Windows & Doors, from the first phone call to the final wipe-down:

1. 1
   Walkthrough and diagnosis. We inspect the window, the frame, and the surrounding wall opening. We want to know whether the problem is the window itself or the installation.
2. 2
   Written estimate with a real number. We hand you a line-item quote before we pick up a tool. No range, no “we’ll see once we open the wall.” You approve the number, we do exactly that work.
3. 3
   Parts decision. We tell you honestly whether OEM CGI parts are worth the price for this failure or whether a high-grade aftermarket part will perform the same. We don’t push either direction.
4. 4
   The repair. Background-checked, uniformed techs do the work. Ed Winslow still shows up on most job sites in Naples before the job is done, because his name is on the truck and he takes that literally.
5. 5
   Testing and alignment. We cycle the window, check lock engagement, inspect weatherstripping, and verify drainage. Then we clean up and haul off any debris.
6. 6
   The 36500-Day Done Right Promise. If it’s not done right, we come back and make it right. That’s not a one-year conditional promise. It’s the standard we’ve worked under since 2011.

What CGI Impact Windows Cost in Naples

Real numbers, not vague ranges. Here’s what we see on CGI work in Naples:

• Slider roller replacement (one window): $160 to $320, depending on series and track condition.
• Casement operator replacement: $185 to $385, including linkage adjustment and lock alignment.
• Single-hung balance replacement (both balances, one window): $220 to $410.
• Replacement insulated glass unit for a CGI frame: $380 to $900, depending on glass size, tint, and whether it’s laminated impact glass.
• Full impact window replacement with installation (typical opening): $1,400 to $3,800 per opening, driven by size, series, and whether you’re matching existing windows or upgrading all of them.

What moves the price? Glass size, laminated versus non-laminated, frame series, and how much frame flashing or interior trim has to be disturbed. We charge no trip charge in our home county, and we’ll give you a free second opinion on any written estimate you already have. Call (239) 899-6411 for your exact number, and we’ll stand behind it.
