CGI Window Replacement Nationwide

CGI Window Replacement: The Jacksonville Owner’s Guide

CGI window replacement in Jacksonville typically runs $850 to $2,400 per window installed, depending on the series, size, and whether we’re replacing the sash, the glass unit, or the full frame. We stock CGI-compatible parts on our trucks and install replacements across Jacksonville neighborhoods from San Marco to Mandarin, usually in a single visit. Most Jacksonville homeowners discover the problem the Florida way: a window that won’t lock after a storm, condensation between the panes that won’t clear, or a crank that suddenly spins without moving the sash. You know something’s wrong before you know the part name. That’s normal. The fix starts with identifying exactly what failed.

Which CGI Models This Applies To

CGI product lines common in Jacksonville homes include the Estate Collection, the Sentinel series, and the Targa impact-rated line. Each series uses different hardware spec’d for its frame depth and weight rating. A Sentinel sash, for example, won’t seat properly in an Estate frame, even if the glass dimensions look close. The compatibility detail that matters: CGI stamps a series code and manufacturing date on the spacer bar inside the glass unit and on the frame extrusion itself. Before we order or pull any replacement part, we read that stamp and measure the sash pocket width. That’s the difference between a smooth swap and a window that binds on the first hot afternoon.

We stock OEM CGI parts where the series is still in production. For discontinued lines, we use aftermarket equivalents machined to the same lock geometry and cam profile. We’ll tell you which option applies to your window and why, in writing, before we start. One detail worth knowing in Florida: CGI’s laminated impact glass carries different overall thickness than standard annealed units, so a replacement sash built for non-impact glass will not sit flush in an impact-rated frame. We verify that spec on every CGI job.

Signs Your CGI Window Replacement Is Failing

• Condensation or haze between the panes. The sealed glass unit has lost its argon fill or developed a seal breach. Once moisture is inside the unit, there’s no drying it out. The glass gets replaced, not rehabbed.
• Window won’t lock or the lock feels loose. On CGI windows, this usually means the keeper on the frame has drifted or the lock cam in the sash is worn. A forced lock bends the hardware and eventually the sash rail.
• Crank spins without moving the sash. The operator gear teeth have stripped. This is the most common failure we see on CGI casement windows in Jacksonville, especially on the west-facing walls that take full afternoon sun.
• Visible rust or corrosion at the hinges or lock points. Jacksonville’s salt air works on hardware. Once rust starts, the metal swells, and the sash stops seating square. Doors and windows near the Intracoastal usually show this first.
• Drafts or daylight at the sash meeting rail. The weatherstripping has compressed or the frame has settled. In an impact-rated CGI window, a draft also means the structural seal isn’t doing its job the way it should.

Replacement Cost & What’s Included

The installed price for a single CGI window replacement in Jacksonville depends on three things: what failed, which series you have, and whether the opening is standard or custom. The most affordable fix is a balance or operator replacement, which typically runs $185 to $400 installed. A new laminated impact glass unit runs $500 to $1,100 installed. Full sash replacement on an Estate or Sentinel window runs $850 to $1,600, and a complete window-in-frame replacement starts around $1,400 and goes up from there. If the frame itself is damaged from storm impact or sill rot, that’s a full replacement, not a part swap, and the price reflects that.

Every price we quote in Jacksonville is written down before work starts. It includes the part, the labor, the installation hardware, and the cleanup. It does not change at the door. We install with the same discipline on a single window or a full set, and every job carries the 365-Day Done Right Promise in writing. If it fails within that year, we come back and fix it at no charge.

DIY or Call Us?

There’s a narrow list of things you can safely check yourself. You can look for the CGI series code on the spacer bar. You can check whether the lock keeper is visibly loose. You can note whether the issue appears on every window or just one. What you should not do is try to replace a sash, re-tension a balance, or remove impact glass yourself. These assemblies are heavy, and a CGI impact sash under spring tension can cause a serious injury if it releases wrong. The high-tension balance hardware is the same principle as a garage door spring: the stored energy is invisible until it isn’t. We recommend a trained professional for any repair that involves removing the sash from the frame or replacing the glass unit. That’s not a scare tactic. It’s just the truth from three decades of watching these jobs go right, and occasionally watching one go very wrong.
