CGI Window Replacement: The Westgate Owner’s Guide

If you’re searching for CGI window replacement in Westgate, you’re probably holding a failed sash, a fogged impact pane, or a window that won’t seal against the afternoon storms anymore. A full CGI replacement window in Westgate typically runs $900 to $2,400 installed, depending on size, series, and glass package. We stock CGI-compatible hardware and glass packages on our trucks, and most single-window replacements are finished in one visit.

The way most Westgate owners discover a failed CGI window isn’t dramatic. It’s a room that never quite cools down, a rattle during wind gusts, or condensation between the panes that shows up one humid morning and never leaves. You don’t need a full window replacement every time, but when the frame, sash, or glazing bead is gone, a new one is cheaper than fighting it.

Which CGI Models This Applies To

CGI manufactures impact-rated windows across several series lines, and the replacement part has to match the original extrusion profile. In Westgate, we regularly work on CGI’s Estate Collection, Targa, and Sentinel series, plus the older Classic line that’s still in hundreds of homes built between 2005 and 2015. The sticker matters: look for the CGI etching on the glass or a label on the frame’s top interior track. If the label’s gone, we match by measuring the visible glass dimensions and the frame pocket depth, which is the measurement most owners miss.

Here’s the gotcha with CGI specifically: their frames use a proprietary balance system on single-hung and double-hung units. An aftermarket balance that “fits” by width will not operate correctly and will leave the sash fighting you every time you open it. We’ve corrected at least two Westgate installs where another contractor used a generic balance and the homeowner assumed the window was just stiff. OEM hardware is always our first recommendation for CGI. The good news is CGI parts are still actively manufactured and available, and we don’t jack the price up for the privilege. Winslow Windows & Doors is an independent service provider, not affiliated with CGI, but we’ve installed and serviced their product line for over a decade.

Signs Your CGI Window Replacement Is Failing

• Condensation between the panes. The seal assembly around the insulated glass unit has separated, which lets humid Florida air inside and destroys the argon gas fill. This is the most common failure in Westgate because the temperature swings between air-conditioned interiors and 95-degree exteriors put constant stress on the seal.
• The sash won’t stay up or binds halfway. The balance system has weakened or broken. On CGI models this usually means coil springs have lost tension, not that the whole window needs replacing. Sometimes a new balance assembly fixes it; sometimes a warped frame corner means a new sash.
• You can hear wind whistling around the frame. The weatherstripping has compressed past usefulness. If the frame itself is square and the glass is intact, weatherstripping is a parts swap. If the frame has twisted from storm pressure, you’re looking at full replacement.
• The crank or slider roller grinds or skips. The operator mechanism inside the frame has stripped gears. On casement and horizontal slider CGI models, this is a frequent failure after ten-plus years of salt air exposure. A good tech replaces the operator and recalibrates the travel in under an hour.
• Visible algae or black streaks inside the glass pocket. Water is getting past the glazing bead and sitting in the sash cavity. Left alone in Westgate’s humidity, this rots the aluminum pocket and turns a $300 parts repair into a full-window replacement.

Replacement Cost & What’s Included

In Westgate, the most common CGI replacement window sizes run between $900 and $1,600 installed. Larger fixed-glass impact units or windows with special glass packages push toward $2,400. The three things driving cost: glass type (clear vs. Low-E vs. tinted), frame color match, and whether the existing frame can be reused or the rough opening needs rebuilding.

Our installed price includes the new CGI-compatible window, the correct OEM hardware, removal and disposal of the old unit, and sealing to match the original install. We write a line-item quote before work starts, and if the invoice looks different from the quote at the end of the job, we’ve done something wrong and we eat the difference. That’s how we’ve done it since Ed founded Winslow Windows & Doors in 2011. Every replacement is backed by our Done Right Promise: if it’s not right, we come back and make it right.

DIY or Call Us?

A homeowner can safely handle two things on a CGI window: cleaning the track of debris and silicone spray on the weatherstripping once a year. That’s the maintenance, not the repair. The problem with self-installing a window replacement is that impact-rated frames carry a structural load not present in conventional windows. If the frame isn’t shimmed and anchored to the original torque pattern, you compromise the impact rating and your insurance carrier can deny a future claim.

Glass removal on an impact-rated unit is where most DIY attempts go sideways. These panes are heavy, bonded with structural adhesive, and when they release they release fast. We’ve seen a homeowner in Westgate lose a finger attempting a sash glass replacement. It’s the one time we’ll flatly tell you not to do it yourself. Call us at (561) 468-6136 and we’ll send a background-checked tech in a Winslow uniform who’s done this hundreds of times.
