CGI Window Replacement: The Doral Owner’s Guide

CGI window replacement in Doral typically runs $340-$780 per opening installed, depending on series, glazing package, and whether the frame is salvageable. We stock CGI-compatible sash, hardware, and insulated glass units for same-day replacement on most residential series, and we carry the measured survey to the quote - Haven Clause 1 means the price you sign is the price on the invoice. Most Doral owners discover a problem when they feel airflow around a locked sash, spot condensation between glass layers, or the window refuses to stay open in a second-story bedroom after a storm season.

Which CGI Models This Applies To

CGI manufactures several distinct series, and the replacement part you need depends on which line is in your wall. The Estate Series uses heavier aluminum extrusions and a different glazing bead profile than the Sentinel line, which means a sash built for one will not seat properly in the other. We replace units across the full CGI residential catalog: Estate, Sentinel, Targa, and Impact Resistant lines, plus the commercial-grade Series 9000 storefront systems found in some Doral townhome associations.

To identify your series, check the etched mark in the glass corner or the label on the frame header. The etching includes the NFRC certification number and the glazing spec - write that down before you call. If the label is painted over, which we see often in Doral’s newer construction near Downtown Doral, measure the frame depth and the visible glass dimensions; we cross-reference those against CGI’s extrusion drawings.

OEM parts from CGI’s Opa-locka distribution center match exactly but carry a longer lead time for discontinued series. We also source quality aftermarket equivalents from our verified lines when the OEM part is back-ordered, and we document the substitution in your written scope - Haven Clause 5, no surprises. The aftermarket decision is yours; we price both and explain the warranty difference.

Signs Your CGI Window Replacement Is Failing

• Condensation between glass panes. The insulated glass unit (IGU) seal has failed, allowing moist South Florida air into the cavity. In Doral, we see this accelerate when the desiccant inside the spacer bar saturates - usually 8-14 years in our humidity, sooner if the window faces afternoon sun.
• Sash drops or won’t stay open. The balance system, either a coil spring or block-and-tackle type depending on CGI series, has lost tension. On upper-floor units, this is a safety issue; a dropped sash can pinch fingers or crack the glass.
• Airflow around a locked frame. The weatherstrip has compressed or the sash has shifted in its track. We check with a smoke pencil during survey - a trick Sonia learned at Miami Dade College - to locate the exact leak path before quoting.
• Cracked or shattered impact glass. The outer lite may be intact while the inner laminated layer holds, but the impact rating is compromised. Florida building code requires the full IGU replacement to maintain the HVHZ certification on the opening.
• Hardware operates roughly or not at all. The multipoint lock or tilt latch has corroded, which is common within 3 miles of Doral’s golf course irrigation and the canal systems. We stock stainless replacements that outlast the original zinc alloy parts.

Replacement Cost & What’s Included

What drives the range: the glazing package (single-pane, laminated, or insulated laminated), whether the existing frame is square within 1/8 inch, and whether we need to match a discontinued color finish. Our quote includes parts, labor, disposal, and the documented photo record - no line item is added after you sign. Every replacement carries the 365-Day Done Right Promise under the Haven Standard. If the sash drags or the seal fails in that window, we return and correct it.

DIY or Call Us?

There is a safe middle ground. You can verify the model number, photograph the failure, and check for visible frame damage - that information saves us time and saves you money on the survey. What we do not recommend: removing a sash with a failed balance, cutting glazing tape, or handling laminated glass without proper support. An unsupported IGU can flex and crack in your hands, and a dropped sash on a second-story opening in Doral is a liability you do not need.

We are an independent service provider - not affiliated with CGI - and we carry the measured survey, the written price, and the background-checked crew to your door. Call (786) 460-1563 to schedule your free estimate. Measure it right the first time. Everything else follows from that.
