CGI Window Replacement: The Fort Pierce Owner’s Guide
Replacing a CGI window in Fort Pierce typically runs $850 to $2,400 installed, depending on the series, size, and whether the frame is salvageable. We stock a range of CGI-compatible replacement sashes and hardware on the truck, and most single-unit jobs are done the same visit. Most homeowners discover a problem the way the weather announces itself here: a window that won’t seal before the afternoon storm, a crank that skips, or glass that fogs between the panes and never clears.
We are an independent service provider. We install, service, and replace CGI windows, but we are not affiliated with CGI or its parent company. That independence matters when a homeowner needs an honest read on whether a forty-dollar part fixes the window or the sash itself is done.
Which CGI Models This Applies To
CGI builds two families you are likely to have in Fort Pierce: the Estate Collection (aluminum, hurricane rated, found on half the concrete-block homes from Vero to Port St. Lucie) and the Sentinel series (vinyl, a later line that shows up on newer construction). Within each you will find fixed, single-hung, casement, and horizontal roller windows. The parts are not interchangeable across families. An Estate sash will not sit in a Sentinel frame, and the locking hardware is different enough that mixing them is how a homeowner ends up with a window that passes a visual check and fails the first wind test.
Finding your model is straightforward. Open the sash and look at the lower corner of the frame. CGI stamps a series code and size callout there on most units built after 2005. Older windows lose the stamp to sun and salt air; in that case we measure glass dimensions and frame depth in place. Then we quote the OEM replacement side by side with a quality aftermarket equivalent and let you see both prices on paper before you decide. For CGI specifically, OEM makes sense on load-bearing hardware: lock assemblies, hinge arms, and the interlocking meeting rails on Estate windows. Aftermarket glass units are often the better buy, since the laminate meets the same Miami-Dade specs and comes from the same glass suppliers CGI uses.
Signs Your CGI Window Replacement Is Failing
- Condensation between the panes that does not clear. The seal has failed. In Fort Pierce, we see this most often on western-facing glass that catches afternoon sun and salt air. The insulating value is gone, and the only real fix is glass replacement, not a repair.
- The crank turns but the sash does not move. The operator gear has stripped, usually because the window was forced against a bind. On CGI casements, the operator is a replaceable part, but if the sash frame is racked, the new gear will strip the same way in a season.
- You have to lift the sash to close it. The block-and-tackle balance on a single-hung has lost tension or snapped. This is not a window you ignore through hurricane season. A sash that drops closed can also be a finger-breaker, and we have replaced more than a few balances for owners who put this off.
- The window locks but the corners still rattle or leak air. The interlock along the meeting rail has worn, or the corner keys in the frame have loosened. You may not see daylight, but run a hand along the seam during a breeze and you will feel it.
- Water stains below the window after heavy rain. The problem is usually not the glass. It is the frame seal or the flashing outside. Water is patient and finds the path of least resistance. Once the drywall starts to stain, the leak has been there a while.
Replacement Cost and What’s Included
Here are the installed price ranges we quote in Fort Pierce:
| CGI Replacement | Typical Installed Range |
|---|---|
| Glass unit only (seal failure, same sash) | $350 – $750 |
| Complete sash replacement (same frame) | $600 – $1,100 |
| Full window replacement (frame included) | $1,100 – $2,400 |
| Hardware replacement (lock, operator, balance) | $180 – $400 |
What drives the spread is mostly size and glass type. A fixed-picture window with clear glass costs less than a casement with impact laminate and a Low-E coating. We write the parts and labor separately on every quote, so you see exactly what the hardware costs and what the install costs. No hidden line items. No “the frame was worse than expected” upcharge after the window is out. And every replacement carries the Done Right Promise on our work plus both warranty layers registered in writing before the truck leaves the driveway.
DIY or Call Us?
Some things an owner should absolutely do. Check the weep holes at the bottom of the frame and clear them of dirt and pine needles. Lubricate hinges and tracks with a dry silicone spray once a year. Wipe down the weatherstripping and check for tears before June.
What a homeowner should not do is pull the sash out of a CGI Estate window without knowing how the balance is tied. When a block-and-tackle assembly lets go, the spring tension is stored in a metal channel that can cut you on the way out. We have seen the result of a homeowner prying a stuck sash with a flathead and a short temper. The sash wins. If the window is fogged, stripped, or racked, call us at (772) 218-5890. We will measure it, quote it, and tell you honestly whether the part or the whole window is the right call.
If it is not right when the caulk dries, it will not be right in two years either.
FAQs
In our coastal climate, a CGI window gives real service for twenty to thirty years. The glass laminate and frame can go longer. What fails first is the hardware: operators, balances, and the weatherstripping that takes a beating in salt air. We also stock and install parts for Andersen, and Pella if you have a mixed house.
The glass unit needs replacement. Once the seal fails and moisture gets between the panes, the insulating gas is gone and the only durable fix is a new sealed unit measured to your sash. Call (772) 218-5890 and we will measure and quote it without charging for the look.
A single-hung sash or glass unit usually takes one visit, roughly an hour and a half from setup to cleanup. A full-frame replacement runs a half day. We schedule it, show up when we say, and don’t leave a second appointment hanging over your week.
We keep common CGI replacement hardware and balance assemblies on the truck. Glass units are ordered to spec because the laminate and Low-E coating are cut per window. Typical turnaround is one to two weeks, and we tell you the date before you commit.
