CGI Window Replacement: The Miami Shores Owner’s Guide

If you have a CGI window that’s failed, fogged, or blown out, we stock and install CGI-compatible replacement windows throughout Miami Shores, with most complete window replacements running $850 to $2,400 fully installed depending on size, series, and glass package. We can usually have your replacement ordered and scheduled within days, not weeks, because we keep common CGI glass packs and hardware on our trucks and know exactly which series your Miami Shores home was likely built with.

Most homeowners in Miami Shores discover they need a CGI window replacement the hard way: a bedroom window won’t close flush after a storm, condensation has crept between the panes, or the laminate glass has spiderwebbed but not shattered. Sometimes it’s a crank operator that snapped or a balance shoe that gave out. Whatever the failure, the fix starts with identifying your exact CGI series, because CGI has built several distinct window lines over the years and they don’t all take the same parts.

Which CGI Models This Applies To

CGI’s main window lines we replace in Miami Shores homes include the Estate Collection, the Sentinel series, and the older 9400/9600 series that went into a lot of Miami Shores houses built or renovated between 1995 and 2015. The Estate Collection uses a different frame depth and glazing bead than the Sentinel, and the 9400 series uses an entirely different balance system. Here’s the compatibility gotcha: a glass pack cut for an Estate window will not seat properly in a Sentinel frame, even if the visible glass dimensions match. The locking channels differ by roughly 3/16 of an inch.

To identify your CGI series, look for a silver or white sticker on the inside of the frame near the top or bottom sash rail. If the sticker’s gone (common after years of Miami sun), we can identify the series by the frame profile and the style of the locking hardware. We also match the glass itself: CGI impact windows in Miami Shores generally ship with laminated glass meeting Miami-Dade HVHZ standards, and the replacement needs to carry the same rating. We source OEM CGI glass packs where available, and use high-quality aftermarket equivalents only when CGI has discontinued the glazing. Either way, the replacement is impact-rated and carries our workmanship warranty.

Signs Your CGI Window Replacement Is Failing

• Condensation between the panes. The seal has failed and moisture is now trapped in the insulated glass unit. In Miami Shores humidity, this shows up fast and will never clear on its own. The glass pack needs replacing.
• The sash won’t stay up, or drops when you release it. The balance coil or balance shoe inside the frame is worn out. CGI balances are sized to the exact sash weight, so a generic replacement from a hardware store will either be too weak or too stiff.
• Crank, hinge, or lock hardware snapped or stripped. CGI hardware is robust, but salt air in Miami Shores accelerates corrosion on aluminum and zinc components. A stripped crank gear or corroded hinge is a mechanical replacement, not a full window replacement.
• Visible spiderwebbing or cracks in the glass. Laminated impact glass can crack but hold together (that’s the design). Even so, a cracked pane has lost its structural integrity and no longer meets impact code. It needs replacing before the next storm season.
• Water or air leaking around the frame. Often this is a failed seal between the frame and the rough opening, not a glass failure. If left alone in Miami Shores, water intrusion rots framing and invites mold. We fix the flashing and reseal the opening, replacing the window only if the frame itself is compromised.

Replacement Cost & What’s Included

For Miami Shores homeowners, a CGI window replacement typically runs:

• Glass pack only (seal failure or cracked pane): $350 to $900 installed, depending on size and glass type
• Hardware repair (crank, hinge, balance, lock): $120 to $450 installed
• Full window replacement (new frame and glass): $850 to $2,400 installed, depending on size, series, and finish

What drives the range? Size is the biggest factor, followed by series. A 36-by-60 Sentinel costs more to replace than a 24-by-36. Glass package matters too: standard laminated impact, Low-E, and tinted options all carry different prices. Every quote we give includes the part, labor, disposal of the old unit, and sealing/flashing work. No separate line items that appear after the fact. And the work is backed by our Done Right Promise: if it’s not done right, we come back and make it right. Ed Winslow’s name is on the door, and on every job we do.

DIY or Call Us?

Here’s the honest split. Things you can safely check yourself: whether the lock or crank is obviously broken, whether the glass is cracked or fogged, and whether the frame itself is square. That tells us what to bring. What you shouldn’t attempt: removing a CGI sash or glass pack yourself. These windows are heavy, the balances are under tension, and a mishandled sash can do real damage to you or the window. Impact-rated frames are also intolerant of forced removal; prying on the glazing bead without the right tools cracks the bead and turns a $400 glass swap into a $1,200 frame replacement.

If you’re in Miami Shores and your CGI window is acting up, call us at (727) 483-7883. We’ll tell you whether it’s a repair or a full replacement, and what each path costs before anything gets started.
