Trusted Custom & Geometric Windows for Coral Gables Homeowners
Custom and geometric windows in Coral Gables are not an off-the-shelf product. They are a glazing craft that requires field measurement, custom fabrication, and an installer who understands how Mediterranean Revival and Spanish Colonial architecture puts curves, arches, and odd angles where standard rectangles do not belong. TruePane Windows & Doors has measured, ordered, and set shaped windows throughout Coral Gables for homeowners who learned the hard way that a wrong radius or a fudged rough opening means a window that leaks, binds, and voids the manufacturer’s warranty. Dale Kessler has run crews on these jobs since 2008, and the rule has not changed: if the pane is not true, the job is not done.

What Our Custom & Geometric Windows Service Includes
Custom Impact Windows
Custom impact windows combine South Florida’s hurricane code requirements with an opening that was never designed for a stock size. Coral Gables homes built in the 1920s and 1930s often have masonry openings that have settled out of square by a quarter inch or more, and forcing a standard impact unit into that opening is how you end up with stress fractures and a voided warranty. TruePane measures every opening in the rough, not just the visible frame, then orders each impact window to the exact dimensions, including custom laminated glass packages that meet Miami-Dade County product approval standards. We register the manufacturer’s impact warranty and our own 90-day labor promise in writing before we leave the job.

Geometric & Shaped Windows
Geometric windows are the triangles, trapezoids, pentagons, hexagons, and parallelograms that give Coral Gables architecture its distinct character. These are not decorations; they are structural openings that carry wind load, shed water, and need to be set square, sealed correctly, and flashed so water never finds the rough opening. TruePane orders each geometric unit from the manufacturer with the exact angles, frame depth, and glass package specified on the shop drawing, so what arrives is what the opening calls for. We have set shaped windows that other shops declined to quote because the rough opening was out of square by nearly half an inch, and we made it right the first visit.

Arched & Curved Windows
Arched and curved windows are the single most common source of retrofit grief in Coral Gables. A springline height measured wrong by three quarters of an inch means the window does not seat, the exterior trim will not close the gap, and the homeowner is left with a job that has to be torn out and redone. TruePane uses a full-height story pole and checks the radius at three points on every arched opening before the order is placed, because we would rather spend an extra half hour measuring than try to explain a reorder to a homeowner who has already lived through one failed job. We handle full-radius, half-round, eyebrow, and segmental arches in wood, aluminum, vinyl, and composite.

Oversized Openings
An oversized window opening is anything wider than roughly eight feet or taller than about six feet, and these jobs are where structural engineering meets glazing. Coral Gables estates with picture windows, window walls, or pass-through openings need headers checked, dead loads verified, and glass packages engineered for both impact and deflection. TruePane pulls permits where required, coordinates with the structural engineer when the opening calls for it, and never cuts a header or trims a king stud to make a window fit. The point of an oversized opening is light and proportion, and no amount of caulk will fix a window that was designed wrong. We set it true, flash it right, and stand behind it.

Brands We Service for Custom & Geometric Windows
CGI and ES Windows are two of the lines we order most often for custom and geometric openings in Coral Gables, and for good reason. Both fabricate to the opening, not from a stock list, which means an arched transom or a five-sided gable window arrives with the correct radius, the correct angles, and the correct impact rating for Miami-Dade County. We have ordered hundreds of custom units from each brand, and we know their lead times, their frame options, and which glass package makes sense for a window that faces the afternoon sun on a Coral Gables lot with no shade.
ECO Window Systems rounds out the lines we commonly recommend when the homeowner wants a thermally broken aluminum frame with an impact package and a cleaner sightline. We also work with CWS when the job calls for it. The point is not which brand we prefer; the point is that we put the options on paper side by side, with prices, lead times, and warranty durations stated, so the homeowner decides with full information. Whether you have one of these brands already in the house or any other make, we can measure it, source it, and set it right.
Signs You Need Custom & Geometric Windows Right Now
- Fogged glass in a shaped or arched unit. A failed seal on a geometric window is not just an eyesore; it means the insulating gas has escaped and the window has lost its thermal and acoustic performance. Shaped units cannot be reglazed in the field by most shops, which means the entire sash or frame usually gets replaced. We diagnose it in one visit and tell you honestly whether you need a new unit or a glass-pack replacement.
- Water staining beneath an arched or curved window. A radius window that leaks is almost always a flashing failure at the springline or an out-of-mate condition between the frame and the stucco. Coral Gables gets seventy-plus inches of rain a year, and water that has been getting behind the exterior finish is doing damage you cannot see yet. We trace the leak to its source, not to a bead of caulk that buys six months.
- A window that binds, won’t close, or has a visible gap in the frame joint. Geometric and arched windows carry their own weight differently than rectangles, and a corner joint that has opened up means the frame is moving. That movement only gets worse in the summer humidity when wood swells and aluminum expands. A binding window is a heat load problem and a security problem. We address it before it becomes a full tear-out.
- Cracked or impact-compromised glass in a non-standard size. A stress crack in a trapezoid or a circular window almost always points to an installation problem or a frame problem, not a defect in the glass itself. If the glass is compromised, the window no longer meets the impact rating it was sold with. We replace the unit to code and document the new warranty in writing.
- You are planning a renovation that changes wall openings. Adding a pass-through, replacing a picture window with a sliding door, or converting a flat window to a bay changes the structural math. We would rather be in the room when the plans are still being drawn than arrive after a new opening has been framed too small. Dale Kessler has been on hundreds of Coral Gables job sites, and the pre-construction conversation is where most problems get prevented.
Our Custom & Geometric Windows Process - Step by Step
Step 1: You Call, a Person Answers
No phone tree, no callback form. Someone at TruePane answers the phone around the clock and schedules a measurement visit that works with your day. We ask a few questions about the opening and the symptoms so the technician arrives prepared.
Step 2: Field Measurement and Assessment
A background-checked, uniformed technician comes to your Coral Gables home and measures every opening in the rough: width, height, diagonal, springline, radius, and frame depth. We check the condition of the existing frame, the header above the opening, and the flashing below it. This is the step where we tell you the truth, even when the truth is that the opening needs framing work before a window can go in.
Step 3: Side-by-Side Quote on Paper
We put the manufacturer options down in writing with line-item pricing, glass package specs, lead times, and warranty durations stated. You see exactly what you are buying, and the price we quote is the price on the bill. There are no change orders written after the truck is parked in your driveway.
Step 4: Order, Permit, and Install
We place the order with the manufacturer using our shop drawings, pull the permit where the job requires it, and coordinate any structural work that the opening calls for. Our technicians set the window true, flash it, seal it, and clean the site before they leave. If a pane is not true, we do not call the job done.
Step 5: The Written Promise
Before the truck leaves, we hand you the warranty paperwork with both manufacturer warranty layers registered and the durations stated in writing. Our Done Right Promise covers the workmanship, and if something is not right, we make it right. No paperwork fight, no arguing, no fine print.
How Much Does Custom & Geometric Windows Cost in Coral Gables?
A custom geometric or shaped window in Coral Gables runs from about $1,800 for a single, small fixed triangle with a standard glass package to $6,500 or more for a large arched or curved unit with impact glass and a thermally broken frame. A full-wall oversized opening with structural work and site-glazed glass can exceed $15,000 when engineering and permits are involved. These are honest ranges for this market, and they reflect the fabrication, freight, glazing, and labor costs that no reputable shop can avoid.
| Window Type | Typical Coral Gables Price Range |
|---|---|
| Small fixed geometric (triangle, trapezoid, up to 12 sq ft) | $1,800 - $3,200 |
| Arched or half-round unit (standard glass) | $2,500 - $4,800 |
| Arched or half-round unit (impact glass) | $3,800 - $6,500 |
| Oversized custom window (8+ ft wide, structural) | $6,000 - $15,000+ |
What affects the price most is the opening itself: the radius on an arch, the angle accuracy on a pentagon, the glass package, and whether the existing frame and header are sound. You avoid overpaying by getting a written quote with the manufacturer listed, the glass spec written down, and the warranty duration stated. Our free estimate includes all of that and a line item for every cost, so you are comparing real numbers, not handshakes. Call (954) 507-3613 and we will come measure the opening and give you a number that holds.

Frequently Asked Questions - Custom & Geometric Windows in Coral Gables
A custom window is any unit built to a specific opening’s dimensions rather than pulled from a manufacturer’s stock list. Geometric windows are the non-rectangular shapes: triangles, trapezoids, pentagons, hexagons, circles, and arched units. In Coral Gables, these windows are common in Mediterranean Revival, Spanish Colonial, and mid-century homes, and they require field measurement plus a manufacturer that fabricates to order.
Most custom window jobs in Coral Gables have a three-part timeline: one measurement visit, a fabrication lead time of four to eight weeks depending on the manufacturer and glass package, and one to two days on site for a typical single opening. Oversized work with structural changes takes longer, and we will tell you the schedule in writing before the order goes in. Call (954) 507-3613 if you need a specific timeline for your project.
Expect to pay $1,800 to $6,500 for most shaped and arched windows, with oversized openings running higher when structural work is required. Impact glass, thermally broken frames, and unusual radii push the price toward the top of the range. Our free estimate gives you a written, line-item price that does not change after the truck arrives, and the estimate carries no obligation.
Yes. We order custom and geometric units from all three brands regularly and we are familiar with their fabrication tolerances, glass packages, and warranty structures. We also work with CWS and other manufacturers when the job calls for it. You will see the brands side by side on paper with prices and lead times, and we register the warranty for whichever line you choose.
If a geometric or arched window is broken and the opening is exposed, call us right away and we will get a technician out to secure it. A live person answers around the clock, and we can board and measure the same day in most Coral Gables locations. The replacement unit itself follows the normal fabrication timeline, but the opening will be safe and dry in the meantime.
You get two layers of warranty and both are registered in writing before our truck leaves the driveway. The manufacturer’s warranty covers the window and glass per the stated duration, and our Done Right Promise covers the labor. If the work is not done right, we make it right without a paperwork fight.
Clear furniture away from the window so we can set a ladder and work unimpeded, and if you have original plans or a previous window order, have them handy. We do the rest: rough opening measurements, radius checks, frame assessment, and a written quote. You do not need to empty the room, just give us access to the opening.
