AfterCGI Custom & Geometric Windows in Hialeah: What to Know First
We repair and replace CGI custom and geometric windows across Hialeah, from arched and radius units on Palm Avenue ranches to oversized trapezoid openings on newer Mediterranean builds. Most CGI custom window jobs in Hialeah run in the $800 to $3,200 range depending on geometry, glass package, and whether we’re replacing the sash or the full frame. Turnaround is typically 3 to 10 business days once we measure, and every job carries the Done Right Promise.
This page is for Hialeah homeowners and property managers who already own CGI windows, specifically the shaped and non-rectangular units that big-box installers won’t touch. If you’ve got a leaking arch, a radius window that won’t seal, or an octagon that’s suddenly got condensation between the panes, call us at (850) 998-3090. We’ll give you a straight answer on whether it’s repairable or time to replace, and a written line-item estimate either way.
How CGI Products Fail, and How We Fix Them
CGI makes tough windows, but they’re not invincible, and Hialeah has a way of finding the weak points. Here’s what we actually see on service calls.
- Arch-top sashes (Estate Collection): thermal seal failure at the apex. The curved glass on arched CGI Estate units tends to lose its inert gas fill at the highest point of the bend first. You’ll see a milky haze or condensation you can’t wipe off. Hialeah’s afternoon heat expands the aluminum frame unevenly and accelerates the seal breakdown. We deglaze, replace the insulated glass unit with a fresh one cut to CGI’s exact radius spec, and re-seal with structural adhesive rated for South Florida humidity.
- Trapezoid and pentagon fixed units (Sentinel line): frame racking from settling slab foundations. Hialeah sits on porous limestone and a lot of older homes were built on slabs that move. When a fixed geometric CGI frame gets torqued out of square by even a quarter inch, the corners lose compression and water finds a path during summer downpours. We pull the unit, shim and re-square the rough opening, and set the frame back with fresh sealant joints at the corners, which is where 90 percent of the leaks actually start.
- Radius operable windows (CGI Estate casement/awning): hinge hardware corrosion. CGI’s hardware is marine-grade, but the salt-laden air that rolls through east Hialeah off the bay still eats at pivot pins and operator arms over time, especially on homes within a couple miles of the water. A radius awning window that suddenly won’t crank smooth is almost always a corroded operator, not a bent frame. We replace the operator assembly with OEM CGI hardware when it’s available, or a direct-match aftermarket assembly that preserves the original geometry.
- Oversized geometric fixed lites (Targa by CGI): gasket compression set. The Targa line’s heavier glass loads put real pressure on the perimeter gaskets, particularly on big trapezoids that face full western sun. After eight or ten Hialeah summers, the gaskets compress permanently, shrink slightly, and start letting air and water sneak past the edges. The fix is straightforward: we pull the stop, replace every gasket with fresh EPDM cut to the exact profile, and bed the unit down again. The glass is usually fine.
- Geometric impact windows with interior condensation (Sentinel and Estate): failed dual-seal system. When both panes show moisture between them on a shaped unit, it’s not the caulk bead around the outside. It’s the dual-seal between glass and spacer inside the IG unit itself. On geometrically-shaped glass, this often begins at the tightest radius corners where the sealant bead runs thinnest. The only correct fix is a new IG unit. We measure the shape with digital templates and order a replacement cut to the same corner radii, not just the same width and height.
Our CGI Custom & Geometric Windows Process
Shape work is different from swapping out a standard rectangle, and we treat it that way. Here’s how it goes:
- 1
Call and assessment. You tell us what the window is doing. We ask about the shape, the age, any leaks, any moisture. If it sounds urgent, Ed or one of our senior techs arranges to look at it fast.
- 2
On-site measurement and diagnosis. Every geometric window gets digitally templated, not measured with a tape at three points and hope. We check the rough opening, the frame square, the seal condition, and what failed.
- 3
Parts decision. Some fixes demand OEM CGI components, especially on impact-rated sashes any time the structural integrity of the frame or glass is in play. For hardware and gaskets, we’ll use quality aftermarket parts where they match the original spec exactly and don’t void the manufacturer’s warranty. We’ll explain which is which before any work starts.
- 4
The repair or replacement. We handle the removal, prep, re-glazing, and reinstallation in one visit when possible. On full replacements, we order the new shaped unit and come back when it’s in. No vague “a few weeks” estimates; you’ll know the lead time on the estimate.
- 5
Water test and closure. After any reseal or replacement on a geometric unit, we run a calibrated water test across the corners and apex, the places that fail first. If it doesn’t pass, it’s not done.
- 6
Guarantee and paperwork. Every job closes with your written warranty and a line-item invoice. If something’s not right, the Done Right Promise means we’re back out until it is.
What CGI Custom & Geometric Windows Costs in Hialeah
Here’s what we typically see on CGI geometric work in Hialeah. These are installed price ranges, assuming no structural surprises in the opening.
| Job | Typical Range |
|---|---|
| Thermal seal repair on arch-top IG unit (Estate) | $450 - $850 |
| Corner leak reseal on fixed trapezoid (Sentinel) | $350 - $650 |
| Hardware replacement, radius awning/operable window | $225 - $500 |
| Full replacement, mid-size geometric impact window (36″ x 48″ pentagon or similar) | $1,400 - $2,800 |
| Oversized trapezoid or arch replacement, custom templated | $2,200 - $3,800+ |
What moves the price: glass package (laminated impact glass costs more than non-impact insulated), whether the frame itself is sound, curb-to-second-floor access, and how tight the corner radii are. We don’t charge for the estimate, and we’ll never surprise you with a change order once work is underway. Call (850) 998-3090 for a line-item quote, free.
Why Hialeah Homeowners Call Winslow Windows & Doors for CGI Work
Ed Winslow’s name is on the door, and on every job we do. He grew up in the Westland area of Hialeah helping his uncle patch the old concrete-block homes that line those streets, and he’s never lost patience for the detail work that shaped windows demand. We’ve been at this since 2011, locally owned and not a franchise, with a real address and license you can look up. Our techs are background-checked, uniformed, and know CGI geometry without having to watch a training video on your driveway.
And when we’re not the right fit for a particular CGI shape, we install PGT, CWS, ES Windows, and ECO Window Systems, so you’re never stuck with whatever one brand sells. We’d rather tell you what actually works for your opening than shoehorn in something close enough. That’s the difference between a contractor and a neighbor.
My name’s on the truck and on the warranty, that’s not something we take lightly.
FAQs
In most cases, no. Seal repairs, gasket replacement, and hardware swaps on CGI windows do not void the CGI warranty when done correctly, and we use OEM parts for structural or glass work precisely to keep you covered. If you’re worried, we’ll walk you through what the CGI warranty covers and what it doesn’t before we touch anything.
Lead times on custom CGI geometric units typically run 2 to 6 weeks depending on shape complexity and glass package. Standard-shaped sashes are often available faster. We’ll tell you the lead time in writing before you commit, and nobody at Winslow will promise a window that isn’t actually on the truck yet.
If the frame is square and sound, a failed thermal seal on an arched CGI unit can almost always be fixed by replacing the insulated glass unit, not the entire window. You’ll get clear glass again at a fraction of full replacement cost. If the frame has racked from slab movement, that’s a different conversation, and we’ll show you the measurements that prove it.
Yes. We service both impact-rated and non-impact CGI shaped windows across Hialeah. The seal and hardware failure patterns are similar, but non-impact glass is thinner and generally less expensive to replace when it fails. We’ll confirm what you actually have before we quote, so you’re not paying for impact glass you don’t need or getting quoted for basic glass when your opening needs impact.
No. The price you approve is the price you pay. We put it in writing, line by line. The only time a price changes is if we uncover something structural in the opening that nobody could see before, and in that case we stop the job, show you what we found, and get your written sign-off before any additional work starts.
