CGI Window Installation: The Sarasota Owner’s Guide

CGI window installation in Sarasota typically runs $85-$210 per window in labor when we’re working with existing openings, with full unit replacement landing between $900 and $2,800 installed depending on size and series. We stock CGI-compatible hardware and mounting components on our trucks, so most installation work happens same-day once we’ve confirmed your model. The most common way Sarasota homeowners discover their CGI window needs professional reinstallation is after a storm: the window held, but the frame shifted, the seal broke, or the mounting hardware worked loose enough to let water in around the edges.

CGI builds a serious impact window. The extruded aluminum frames are heavier than most competitors, and the glass packages are engineered for Miami-Dade and coastal code. That weight is a feature, but it means installation quality is everything. A CGI window installed even slightly out of square will bind on the sash tracks, stress the mounting flanges, and eventually leak. Ed Winslow has been installing CGI products across Southwest Florida for nearly two decades, and he’ll tell you the same thing: most “window failures” we’re called out for are actually installation failures from the original job.

Which CGI Models This Applies To

We install and service CGI’s full residential lineup: the Sentinel series, the Estate collection, the Targa line, and the commercial-grade 700/800 series frames that show up on a lot of Sarasota waterfront homes and condos. Each series uses a different mounting flange configuration and frame depth, so the first step is identifying what you actually have. Look for the CGI label etched into the lower corner of the glass or stamped on the frame edge. It’ll give you the series name, the glass package (usually a code like 5050 or 5650 indicating the impact rating), and the manufacturing date.

Here’s a compatibility gotcha most homeowners don’t know: CGI changed their mounting hole spacing on the Sentinel series around 2016, and older frames don’t line up with newer mounting clips. If your home was built or retrofitted before that, we carry both the current OEM clips and the older pattern, because guessing wrong means drilling new holes in an aluminum frame that doesn’t love extra holes. For the Estate and Targa lines, we stock OEM mounting hardware and can source the exact factory gaskets and interior glazing beads, not generic equivalents. On glass replacement within existing frames, we’ll match the original CGI laminated glass specification rather than swapping in a cheaper aftermarket unit that changes the weight balance on the sash. The upcharge for genuine CGI glass versus an equivalent is modest, and on an impact window, that’s not where you want shortcuts.

Signs Your CGI Window Installation Is Failing

• Water staining or soft drywall below the window after rain. This is almost never the window itself. It’s the mounting flange or the exterior seal failing, letting water run behind the frame and into the wall cavity. On Sarasota homes with stucco exteriors, the crack in the stucco channel above the frame is the usual entry point.
• The sash drags or requires force to lock. Aluminum expands and contracts hard in Florida’s heat cycle. If the original install had the frame even slightly twisted, the sash tracks get tighter over the years until the lock stops engaging cleanly. A CGI window that won’t lock is not an impact window anymore.
• Condensation between the glass panes. The factory seal on the insulated glass unit has failed. CGI’s laminated packages can last 30-plus years, but a bad desiccant strip or a seal compromised during original installation shortens that dramatically, especially with Sarasota’s humidity swings.
• You can feel air moving around the frame edges on a breezy day. That’s the interior glazing bead or the exterior seal releasing. It starts as a draft and ends as water entry during a driving rain.
• Cracks in the stucco radiating from the window corners. This is structural movement, likely because the original opening wasn’t flashed or shimmed correctly. The frame is now carrying load it wasn’t designed for, and the stucco is telegraphing the stress.

Replacement Cost & What’s Included

A straightforward CGI window reinstallation, where we pull the existing unit, correct the opening, reflash, and reset the window, typically falls between $350 and $700 per window in Sarasota. Full window replacement, including a new CGI unit, runs $900 to $2,800 installed depending on size, series, and glass package, with most common sizes like a 48″ x 60″ Sentinel landing around $1,400 to $1,900. What drives the range is the condition of the rough opening: if the original install left rotted buck framing or corroded fasteners, you’re looking at sill repair or reframing before the new window goes in.

You’ll get a line-item written quote before we start, so you see the exact split between the window, the hardware, and the labor. No change orders when we discover what’s behind the stucco, no “while we’re here” add-ons unless you approve them first. Every CGI installation we do carries our workmanship warranty, and because we’re an independent local installer rather than a factory rep, we can be honest about what the factory warranty will and won’t cover when a frame issue comes up. We also offer a free second opinion on any written estimate from another contractor, no trip charge inside our home county.

DIY or Call Us?

Impact windows are not a DIY job, full stop. A CGI unit can weigh 200 pounds or more, and the glass is designed to take a hurricane’s abuse without shattering, which means when it does break, it comes apart in sheets rather than harmless cubes. Getting a unit this heavy out of a second-story opening without dropping it through your lanai screen requires equipment and a plan. Even on a first-floor window, the flashing and sealing work has to be correct or you’ll trade a working window for a hidden leak that rots your framing for years before you see the stain.

What you can safely do is identify what’s wrong: check for the frame label, note where the water or air is coming through, and take measurements of the glass only if you can do it from inside. That’s genuinely helpful and speeds up the estimate. Then call us at (941) 267-0779, and someone will pick up. We’ll tell you over the phone whether we think it’s a reinstallation or a full replacement, and schedule a look. No call centers, no voicemail loops. Ed’s name is on the truck, and he stands behind the work.
