CGI Window Replacement: The Fort Myers Owner’s Guide

CGI window replacement in Fort Myers typically runs $850 to $2,400 per window installed, depending on the series, size, and whether you need the full frame or just the sash. We stock CGI-compatible hardware and glass on our trucks, and in most cases we can complete the swap the same day we diagnose the problem. Most Fort Myers homeowners discover they need a CGI window replacement the hard way: a crank that suddenly spins without moving the sash, a slider that grinds against its track after a storm, or a laminated pane that developed a fog between the glass layers that no amount of Florida sun will burn off.

What usually surprises people is that CGI windows are built like tanks specifically because of our climate, but the moving parts still take a beating from salt air, humidity, and the occasional sideways rain off the Caloosahatchee. The glass may be impact-rated, but the hardware and seals are the first things to go. We’ve replaced enough CGI components across Fort Myers, from older homes off McGregor Boulevard to newer builds east of I-75, that we can usually tell you what failed and why before we even take the window apart.

Which CGI Models This Applies To

We work on the full CGI window lineup: the Estate Collection, Sentry Collection, Targa series, and the older Classic and 950/960 series models that are still in a lot of Fort Myers homes built in the 1990s and 2000s. Each series has its own hardware footprint, and this is where generic replacement parts go wrong. A Sentry series casement crank arm is not interchangeable with an Estate series arm, even when they look almost identical side by side. The screw mounting pattern, the arm length, and the gear ratio inside the operator are all different.

If you can find the label, that helps. CGI etches or stickers a series code and manufacturing date on the frame or the spacer bar between glass panes, usually on the corner of the sash. If the label is faded or painted over, take a photo of the window hardware from the inside and measure the visible glass area, not the frame. We can match almost anything from those two pieces of information.

On the OEM versus aftermarket question: for glass and structural components, we recommend OEM CGI or a code-approved equivalent. For hardware like crank operators, locks, and balances, quality aftermarket parts from manufacturers like Truth Hardware and Ashland are often better than the originals because they include design fixes for the exact failure modes we see after years of Florida weather. We’re an independent service provider, not a CGI factory branch, which means we carry both and give you the honest recommendation based on what failed and how long you plan to stay in the home.

Signs Your CGI Window Replacement Is Failing

• The crank turns but the sash barely moves. The operator gear inside the crank housing is stripping, which happens after years of salt-laden air working into the mechanism. This is the single most common CGI casement failure we see in Fort Myers because the coastal air is merciless on exposed gears.
• Fog or condensation trapped between the panes. This means the edge seal on the insulated glass unit has failed and moisture is now inside. Once that happens in Florida’s humidity, the fog never goes away on its own, and the energy efficiency of that pane is permanently compromised.
• You hear a grinding or scraping when sliding the window. The rollers or glides have worn flat, or the track itself has corroded from years of weather exposure. Continuing to force it will damage the frame channel, turning a roller swap into a much larger repair.
• The sash drops or won’t stay up. On single-hung and double-hung CGI models, the balance system has lost tension. That’s a spring-loaded component under the sash, and while a homeowner can replace balances on some models, it’s one of those jobs where one wrong move turns a $200 fix into a broken pane.
• Water staining or soft drywall below the window after rain. The window itself may still look fine, but the weatherstripping or sealant flange has failed and water is getting behind the frame. In Fort Myers we see this most often on south-facing windows that eat direct sun every day and bake the sealant until it cracks.

Replacement Cost & What’s Included

Here’s what CGI window replacement costs in Fort Myers, based on the jobs we’ve done across Lee County:

• Hardware-only replacement (crank operator, lock set, rollers): $180 to $360 installed.
• Insulated glass unit replacement (seal failure, fogged pane): $420 to $850 per sash, including new glass, desiccant spacer, and re-glazing.
• Full sash replacement (damaged frame member or sash, or matching a discontinued series): $650 to $1,100 installed.
• Complete window replacement (full frame, impact-rated, code-compliant): $1,200 to $2,400 per opening, installed with permit and inspection.

The range comes down to three things: the window size, the CGI series, and whether the frame itself is still solid. A Sentry single-hung with fogged glass is a simple glass swap. A 20-year-old Estate casement with a stripped operator, corroded track, and failing sealant is a bigger job. Every quote from us is a line-item breakdown of parts, labor, and any permit or disposal fee, before you approve anything. The price we write is the price you pay. No change orders, no “we discovered more damage” upcharge later. And every CGI window replacement we do in Fort Myers falls under the 36500-Day Done Right Promise: if it’s not done right, we make it right.

DIY or Call Us?

There are two things a homeowner can safely check before calling us. First, inspect the visible hardware for loose screws or obvious corrosion. Tightening a loose crank arm screw takes 30 seconds and occasionally resolves the problem. Second, check the weep holes along the bottom track of a slider or single-hung. Fort Myers pollen and dust clog them constantly, and a clogged weep hole causes water to pool and wick into the frame.

Beyond that, we’d tell you to stop. The balance springs inside hung windows carry serious tension, and a sudden release can break a hand or shatter the glass. Re-glazing an impact-rated CGI sash without the right tools usually ruins the sash or voids your remaining factory warranty. And if the laminated glass itself is compromised, that’s simply not a homeowner job. Call us at (239) 453-7751. We’ll diagnose it, give you a fixed price, and have it handled before the next afternoon thunderstorm rolls through.
