CGI Window Replacement Nationwide

CGI Window Replacement: The Miami Owner’s Guide

CGI window replacement for a failed sash, balance, or glass unit in Miami typically runs $180 to $640 installed per window, depending on the series and whether you need the full sash or just the glass. Most CGI parts are in our Miami warehouse or can be pulled within two business days, and we do same-week installs for most replacements. The way most owners find out something failed is simple: a window that won’t stay up, a latch that won’t catch, or glass that fogs between the panes after a hard rain. You don’t always need a whole new window, and we’ll tell you that straight before we ever quote you a full replacement.

I’m Owen Satterfield, and I’ve been installing and servicing impact-rated windows in Miami long enough to know that CGI parts fail in specific, predictable ways. Salt air works on the hardware. UV beats on the weatherstripping. And the humidity finds every weak seal. Tell me what you’re dealing with, and I’ll tell you straight what it’ll take to fix it.

Which CGI Models This Applies To

We replace and install components across the main CGI product lines: Sentinel, Estate, Estate Collection, Targa, and the CGI Commercial Series. The compatibility gotcha that trips up most Miami homeowners is this: CGI glass units from the Sentinel line do not interchange with Estate series sashes, even when the rough opening measurements are identical. The frame profile depths and glazing bead styles are different, and forcing the wrong unit into the frame is how you end up with a warranty-voided window and a leak that shows up in the next named storm.

To identify your model, check the aluminum frame on the hinge side. CGI stamps a permanent label there with the series name, model number, and manufacturing date. If the label is faded or missing, we can still match it: measure the visible glass width and height, then the frame depth, and we’ll cross-reference it against CGI’s spec sheets. When OEM parts are available, we install OEM. When a CGI part is discontinued or on backorder, we’ll give you a quality aftermarket equivalent and tell you exactly what differs, so you’re making an informed call, not a blind one.

We’re an independent service provider. We are not affiliated with CGI, but we install more of their product than most dealers in Miami-Dade because homeowners with existing CGI windows want replacements that match what they already have. We also stock parts for PGT, CWS, and ES Windows when the job calls for it.

Signs Your CGI Window Replacement Is Failing

• Fog or condensation between the glass panes. The seal on the insulated glass unit has failed. In Miami’s humidity, this shows up fast once the desiccant inside the spacer is saturated. The glass unit needs replacement, not the whole frame.
• Sash won’t stay up or drops when you raise it. The block-and-tackle balance inside the jamb has worn out. CGI balances are sized by sash weight and series; the wrong replacement balance either slams the sash or makes it impossible to lift.
• Latch or lock won’t engage. Salt corrosion is the usual culprit on Miami windows near the coast. CGI’s multi-point locks can seize internally. Sometimes it’s a cleaning and lubrication job, sometimes the lock body needs replacing.
• Water staining on the interior sill or wall below the window. The glazing bead or sill dam has failed, or the frame anchors have pulled loose after years of wind-load cycling. This is the one you don’t ignore, because water intrusion rots the buck and the drywall before you see the stain darken.
• Window is harder to open or close than it used to be. The rollers on sliding windows or the hinge arms on casements and awnings have worn flat. In Coral Gables and Coconut Grove, tree canopy and salt air together shorten roller life by a couple of years compared to inland installs.

Replacement Cost & What’s Included

Here’s what CGI window replacement parts cost in Miami, installed:

• Insulated glass unit replacement (seal failure / impact glass): $180 – $360 per sash
• Sash replacement (frame and glass, CGI-compatible): $220 – $480 per sash
• Balance replacement (both sides, block-and-tackle): $140 – $230 per window
• Multi-point lock replacement: $120 – $210 per lock body
• Full-frame window replacement (CGI or equivalent impact-rated): $850 – $1,400 per window installed, depending on size and series

The spread exists because CGI made different series with different aluminum wall thicknesses and glazing options. A Targa is not priced like an Estate. Every quote we give is a written, line-item price before work starts, per the Kingswell Guarantee. That’s the whole point of the way we operate: you know the cost of the part, the labor, and the total before a single screw turns. We don’t revise quotes at the door, and we don’t hand you a surprise change order because the job turned out harder than we thought.

DIY or Call Us?

Here’s the honest split. You can safely clean the tracks, check the weep holes for debris, and take photos of the label and any visible damage before you call. That saves both of us time.

What you should not do yourself is pull a CGI sash out of the frame to replace a balance or a glass unit. These sashes are heavy. An Estate series sliding glass panel can run over a hundred pounds, and when one drops, it doesn’t miss. The balance springs are under tension even when the window is closed. Pinching a finger or dropping a sash into a tile floor is the best case scenario. The worst is a broken foot or a shattered impact-glass unit on the ground with you in the path of it. If the part that failed is the glass, the balance, or the locking mechanism, call us at (850) 753-2730. We’ll bring the right part, the right tools, and a second set of hands for anything over sixty pounds.
