CGI Window Replacement in Stuart: What to Know First
CGI window replacement in Stuart typically runs $900 to $2,800 per opening depending on the series, size, and whether you’re doing a full-frame replacement or an insert.

What we give you is a straight price, both warranty layers registered in writing before the truck leaves, and a 90-day promise that if it’s not done right, we make it right.

This page is written for the Stuart homeowner who already owns CGI windows and needs them replaced. Not patched, not caulked, not adjusted. Replaced. If a previous contractor fogged a seal or set a frame out of true, you already know the difference between a quick fix and a real one.
How CGI Products Fail - and How We Fix Them
CGI builds a serious impact window. But every line has its weak points, and after four decades of Treasure Coast work, we know exactly where to look. Here’s what we see on CGI jobs in Stuart:
- Fogged sealed units in the Estate Collection. The laminated glass holds up, but the inner seal eventually lets go in salt air and humidity. Stuart sits between the St. Lucie River and the Atlantic, and that moisture gets into everything. We don’t fog-check and shrug. We pull exact measurements, order a matching insulated glass unit, and reset it with the same care as a new build.
- Binding sashes on CGI 5000 Series casements and awnings. This one is usually the rough opening, not the window. A frame that was shimmed incorrectly or settled over time will torque the hinge path. Dale Kessler grew up reading rough openings, and our rule holds: if the opening is right, the rest is just doing the work. We correct the mounting before we set the new sash.
- Weephole blockages and sill rot on older CGI Sentry Vinyl frames. The Sentry line drains through small weepholes at the sill. When they clog in Stuart’s leaf litter and rain, water pools against the frame and the wood sub-sill rots behind it. We don’t just swap the glass. We check the sill, replace what is soft, and make sure the drainage actually drains.
- Hinge fatigue on CGI H-Class doors and adjacent fixed windows. The H-Class is used on a lot of Stuart waterfront homes, and the constant salt air eats at hardware faster than the glass. When a homeowner wants the window adjacent to a failing door replaced, we check the door’s mounting too. Half the time, the window is out of true because the door shifted first.
- Frame leak paths from caulk joints, not the window itself. This is the one that gets other contractors. A homeowner sees a wet windowsill and assumes the window failed. On CGI aluminum frames, the leak is often in the mullion joints or between the frame and the stucco. We trace the path before we recommend replacement, because replacing a window you didn’t need to replace is a waste of your money.
Our CGI Window Replacement Process
Every CGI job follows the same sequence. No shortcuts, no surprises between the estimate and the final walkthrough.
- 1
Measure twice, in front of you. Our technician checks the rough opening, not just the existing frame. We note what’s square and what isn’t before the old unit comes out.
- 2
Parts decision on paper. We tell you the OEM part number and price alongside any quality aftermarket option that matches the opening. You choose, and we put it in writing.
- 3
Removal without the sledgehammer show. We cut fasteners and release the frame cleanly. If the sub-sill is soft, we tell you before we build over it.
- 4
Set the new unit true. Shims at the corners and midpoint, level and plumb, then anchored per the manufacturer’s torque spec. No “close enough” here. If the pane is not true, the job is not done.
- 5
Seal, trim, and test. We seal the perimeter, flash where the rough opening requires it, and run a water test on the sill. Then we operate the window through the full range of travel.
- 6
Warranty registration before we leave. Both warranty layers - manufacturer and workmanship - are registered in writing, with durations stated, before the truck leaves your driveway.
What CGI Window Replacement Costs in Stuart
Here are the ranges we quote most often on CGI work in Stuart. These are installed prices with trim and basic sealing, not bare-glass numbers.
- Insert replacement, CGI Sentry Vinyl: $900 to $1,400 per opening. This is the most common job we do, and it’s the least invasive. The old frame stays; the new sash and glass go in.
- Full-frame replacement, CGI Estate Collection: $1,800 to $2,800 per opening. Full frame means we pull the old frame to the rough opening and reset everything. More work, more material, longer life.
- Custom sizing or oversized fixed windows: $2,200 to $3,500 per opening. Over a certain width, the glass package and the handling change, and the manufacturer charges accordingly.
- Rot repair at the sill: $200 to $600 on top of the window itself, depending on what we find once the old unit is out. We will not bury rot and call it done.
What moves the price: the frame condition, whether the opening is square (an out-of-square opening means more shimming and careful flashing), local Stuart permitting if structural repair is involved, and whether the CGI line you own is still in production. Call (754) 324-4646 for an exact quote. The estimate is free, and it does not change once the work starts.

FAQs
No, replacing an individual unit with another CGI product preserves your remaining coverage on the frame and home system. We register both warranty layers in writing before we leave, so there’s no ambiguity about what’s covered and for how long. Call (754) 324-4646 if you want us to pull your specific series info and check.
We present both on paper. OEM CGI parts match exactly and keep the line’s original look, but they sometimes carry a longer lead time and a higher price. A quality aftermarket glass package can meet the same impact and energy spec for less, and we’ll tell you which is which on the quote, not after the fact.
Yes, in most cases. The question is whether the adjacent units are near failure too. We will measure, inspect, and tell you honestly if it makes sense to do one now or wait on the others. We don’t upsell glass you don’t need.
Most single-unit replacements are completed in one visit, usually 3 to 5 hours from arrival to cleanup. Custom-ordered units take longer because of manufacturer lead times, but we tell you that before you commit, not after.
Not necessarily. A fogged sealed unit can often be replaced as a glass-only job, saving the frame and several hundred dollars. We will inspect the frame and sill before recommending anything, and the estimate is free either way. Call (754) 324-4646 to schedule that inspection.
