CGI Window Installation: The Sunrise Owner’s Guide

CGI window installation in Sunrise typically runs $340-$780 per opening for standard replacement, with impact-rated units starting around $620 and custom geometries reaching $1,400+. We stock CGI-compatible hardware, fasteners, and sealant profiles on every truck, and most standard replacements are scheduled within 48 hours of the measured survey. Most Sunrise homeowners discover their CGI window needs attention when the sash won’t stay open, they feel air movement at the frame perimeter, or they spot staining on the interior drywall beneath the sill after a summer storm.

Which CGI Models This Applies To

CGI’s product line breaks into three families, and the installation approach differs for each. The Estate Series uses a heavier extrusion with integrated reinforcement channels; the Sentinel Series is the impact-rated workhorse common in Sunrise homes built after 2004; and the Targa Series is the slimmer profile used in non-impact and replacement applications. The label you need is on the interior sash rail, a stamped aluminum tag with the series code, nominal size, and manufacturing date.

Here’s where owners get tripped up: CGI changed its corner key geometry in 2019. A pre-2019 Estate 4000 series frame will not accept post-2019 hardware without a retrofit block, and many online part sellers don’t flag this. We carry both generations on the truck. For fasteners, we use the OEM stainless steel screw pack where the original specification matters for Miami-Dade HVHZ certification, and we stock quality aftermarket equivalents for non-rated replacements where the shear value is the only critical spec. If your original installation was done under permit in Sunrise, the permit record at City Hall will list the exact series and impact rating; we pull that documentation as part of our survey.

Signs Your CGI Window Installation Is Failing

• Sash drift or won’t stay open. The balance system, either a coil spring or block-and-tackle depending on CGI series, has lost tension. In Sunrise’s salt air, the balance housing corrodes from the bottom up because condensation collects in the jamb pocket.
• Visible daylight or air movement at the frame perimeter. The installation sealant has separated from the substrate, or the shims have compressed. This is common in west-facing walls where daily thermal cycling is most extreme.
• Water staining on interior drywall below the sill. The sloped sill pan is either missing, incorrectly bedded, or the weep holes are blocked. CGI’s weep system is external and faces downward; stucco or paint buildup is the usual culprit in older Sunrise installations.
• Condensation between glass lites. The insulating glass unit seal has failed. In CGI’s case, this means the entire sash must be ordered; the glass is not field-reglazable on most series.
• Difficulty latching or visible frame racking. The installation fasteners have loosened, or the rough opening has settled. This is structural, not a part failure, and it will damage the operable hardware if not corrected.

Replacement Cost & What’s Included

The range depends on three factors: whether the existing frame can be retained, whether the replacement unit is in our current stock rotation, and whether the original installation was permitted to current Sunrise code. Our quote includes the measured survey you keep, the written scope with line-item pricing, installation labor, sealant and flashing, and disposal of the old unit. Every CGI installation carries the 365-Day Done Right Promise under the Haven Standard, and the photo record is delivered within 24 hours of completion.

DIY or Call Us?

There is one safe check a homeowner can make: open the sash fully, look at the bottom of the frame, and verify the weep slots are clear of debris or paint. A pipe cleaner or compressed air can clear them. Beyond that, CGI window installation involves structural fasteners, sealant chemistry that must bond to both concrete and vinyl or aluminum, and in impact-rated units, the continuity of the pressure envelope that the inspector will verify.

We have removed DIY attempts in Sunrise where the owner used the wrong fastener type and stripped the jamb reinforcement, or where silicone was applied over dirty substrate and failed within six months. The cost to correct those jobs exceeds the original professional installation. If you are uncertain of your CGI series, the manufacturing date, or whether your wall is block or frame construction, call us at (754) 254-5294. We will schedule the measured survey, give you the written price, and you decide from there.
