Trusted Custom & Geometric Windows for Miami Homeowners
Custom & Geometric Windows in Miami typically cost $850 to $4,500 per window installed, depending on shape, glass package, and whether you need impact rating. Most homeowners choose them for one reason: standard rectangles simply don’t fit the architecture, the view, or the light they want. We’ve been designing and installing shaped windows across Miami since 2011, and Ed Winslow’s name is on every job we do. If you’ve got a round-top, an eyebrow arch, a triangle, a trapezoid, or an oversized opening that other companies walked away from, call us at (844) 901-4551. We answer the phone 24/7, and we’ll give you a straight answer about what’s possible and what it costs.
Miami architecture rewards windows that take risks. Art Deco curves in South Beach, Mediterranean arches in Coral Gables, mid-century angles in Miami Shores Custom & Geometric Windows – none of them fit a stock window from a big-box aisle. We build and install windows that match the geometry of your house, not the geometry of a warehouse shelf. And because we’re a Miami company, every custom unit gets the same scrutiny on wind load, water intrusion, and impact code that we apply to every window we touch.
What Our Custom & Geometric Windows Service Includes
When you call Winslow Windows & Doors about a shaped or custom window, you’re getting the full picture, not a sales pitch. We measure, design, order from brands we’re authorized to install, pull the permit, handle the structure, install, trim, seal, and stand behind it for 100 years under our Done Right Promise. Here’s what that means in practice, broken down by the kinds of custom work we do most often in Miami.
Custom Impact Windows
Florida building code treats impact windows as a structural system, not a finish item. A custom impact window means a window shaped to your opening that also carries a Miami-Dade or Florida Product Approval for wind-borne debris. This matters when the opening isn’t square, when the house predates modern rough openings, or when you want a specific shape that no one stocks in impact glass. We order custom impact units through PGT and CGI, both of which manufacture shaped impact windows with full NOA documentation. Every custom impact installation we do in Miami includes the full permit package and passes final inspection before we call the job done.

Geometric & Shaped Windows
Geometric windows are the non-rectangular units that give a house its silhouette: triangles, pentagons, hexagons, octagons, quarter-rounds, and parallelograms. Miami homes from the 1920s through the 1990s used these constantly, often above front doors, in stairwells, or at gable peaks. When one fails, the fix isn’t a stock window. We measure every angle precisely, order the unit to the degree, and install with flashed openings that shed water the way the original builder meant. We do this throughout Miami, from Westchester colonials to Allapattah Custom & Geometric Windows and South Miami cottages.

Arched & Curved Windows
Arched windows fall into two families: true-radius arches and segmented (eyebrow) arches. A true arch is a continuous curve; an eyebrow arch is made of straight segments that approximate a curve. The distinction drives cost, and you’d be surprised how often homeowners are told they need a true-radius window when a segmented arch would look identical from the street and save real money. We walk you through the difference. We also handle full round-tops, half-rounds, ovals, and elliptical windows, and we order them as complete units rather than piecing together trim to fake the shape. That’s the difference between a window that reads as architectural and one that reads as patched.

Oversized Openings
When an opening exceeds standard window sizing charts, you’re in engineered-territory. Oversized custom windows need heavier glass, stiffer frames, and sometimes a structural header upgrade above the opening. In Miami, where wind loads are among the highest in the country, this isn’t optional. We’ve installed oversized custom units in Fountainebleau living rooms, Miami Springs Custom & Geometric Windows sunrooms, and Coral Gables great rooms, and in each case the window was specified for the exact design pressure of that wall on that house. Before we order anything, we verify the header, the rough opening, and the load path, because a twenty-foot span of glass that deflects in a hurricane is not a window, it’s a liability.

Brands We Service for Custom & Geometric Windows
We’re an authorized installer for eight window and door brands, and for custom geometric work in Miami we lean most heavily on three: PGT, CGI, and ViewLux. PGT is the workhorse of Florida impact glazing, and their custom shop does an excellent job with shaped impact units, particularly true-radius arches and large trapezoids. We’ve installed hundreds of PGT custom windows in Miami and know their lead times, their glass packages, and their frame options well enough to quote accurately the first time.
CGI is the brand we recommend when the job calls for a custom impact window with very high design pressure requirements, the kind you see on waterfront homes in Fort Lauderdale and Hollywood where the wind comes off the water with nothing to slow it down. ViewLux is our go-to for custom non-impact geometric work, particularly when the homeowner wants thermally broken aluminum in a modern profile that reads clean and architectural. And if you have a CWS window or any other make, we service what’s in your home and match new units to what’s already there, when replacement is the honest choice. If you have a brand we don’t list, call us anyway at (844) 901-4551. If we can’t source it, we’ll tell you, and we’ll tell you who can.
Signs You Need Custom & Geometric Windows Right Now
- Water staining or peeling paint below a shaped window. Geometric windows concentrate water at their corners, and Miami’s rainy season tests that geometry every afternoon from June through September. Staining below the sill or bubbling paint along the jamb means the flashing has failed or the frame has warped. Left alone, rot moves into the wall. We see this constantly in Miami Springs homes from the 1950s and 60s, where original geometric windows have simply aged out.
- Visible condensation between the panes of an arched or shaped unit. A sealed glass unit that fogs between panes has lost its argon gas and its insulating value. On a shaped window, the seal is under more stress than on a rectangle because the glass edges run at odd angles. Fogging won’t reverse itself. The fix is a new insulated glass unit cut to your window’s exact shape, which is routine for us and impossible off the shelf.
- A geometric window that no longer opens or closes without forcing it. Shaped windows are heavier than they look because the frame has to carry glass loads in multiple directions. When the sash starts dragging or the operator mechanism grinds, the frame is twisting or the hardware is failing. Forcing it just accelerates the damage. We repair or replace depending on what the frame tells us, and we’ll show you exactly what we’re seeing.
- The window is original to a home built before 1994. Miami’s post-Andrew building code was a dividing line. Pre-1994 shaped windows were rarely impact-rated, often single-pane, and almost always installed with materials that don’t meet current wind-load requirements. If your home in Miami Shores or South Miami still has original geometric windows, they’re not protecting you the way current code expects. Replacing them with custom impact units is both a safety upgrade and a real insurance premium conversation.
- You’re planning a renovation and the contractor wants to square off the opening. This is the one that breaks our hearts. Some general contractors propose framing down a beautiful arched or hexagonal opening to fit a stock rectangle because it’s faster and cheaper for them. You don’t have to accept that. We work directly with Miami homeowners and their builders to keep the architectural character and fit the custom window the house was designed for. Call us before the drywall goes in.
Our Custom & Geometric Windows Process — Step by Step
Custom windows fail when the process is sloppy. Ours isn’t. Here’s what happens from the first call to the final inspection.
- 1
Free in-home consultation and measurement. We come to your Miami home, inspect the existing opening, and measure to the sixteenth of an inch. For shaped windows, we also create a physical or digital template depending on the complexity, because measuring an arc with a tape measure is how expensive mistakes get made. There is no trip charge inside our home county, and you’ll get a written line-item quote with no vague allowances.
- 2
Design and specification. We review glass packages with you, including Low-E coatings, argon fill, impact rating where required, and frame finish. Every recommendation is tied to your specific wall orientation and exposure. A south-facing wall in Miami gets a different glass spec than a north-facing wall, and we’ll explain why. We also verify building code requirements for your address and prepare the permit package.
- 3
Ordering and manufacturing. Custom geometric windows are made to order. Typical lead times run 4 to 10 weeks depending on the brand, shape, and glass package. We order with exact specifications and spot-check every technical drawing before approving production. If the factory sends us a drawing with a wrong radius or angle, we catch it before it ships, not after it’s in your wall.
- 4
Professional installation. Our installers are background-checked, uniformed, and trained on the specific demands of shaped and oversized units. We remove the old window, inspect and repair the rough opening as needed, install the new unit with proper flashing and sealants, and trim the exterior to shed water correctly. For oversized units, we stage the lift so the window goes in square without racking the frame.
- 5
Inspection and the Done Right Promise. When the county or city inspector signs off, we walk the job with you and show you what was done. If anything isn’t right, we make it right. That’s not a slogan; it’s a 100-year promise in writing. If you ever find a problem with workmanship on a custom window we installed, call (844) 901-4551 and we’ll come back. No fine print. No expiration.
How Much Does Custom & Geometric Windows Cost in Miami?
Custom and geometric window pricing in Miami breaks down into three tiers. A standard shaped window like a half-round or eyebrow arch, non-impact, runs roughly $850 to $1,800 installed. Add impact rating and the price climbs to $1,800 to $3,200 for most shapes. Oversized or true-radius arched impact units, the kind you see on Coral Gables or waterfront Miami homes, typically run $3,200 to $4,500 or more depending on size, glass package, and structural requirements. These are real ranges from jobs we’ve quoted and completed across Miami, Hialeah, Coral Gables, and the surrounding area.
Five things drive the price: window area (bigger is more, and oversized glass gets heavy), shape complexity (true arcs cost more to fabricate than segmented brows), impact versus non-impact glass, frame material and finish, and the condition of your rough opening. If the header needs work or the original opening is out of square, that adds labor. We show you every line item before you sign, and our quote is fixed. No change orders. No “we discovered something” surprises. To avoid overpaying, get a written estimate that separates the window cost from the install labor, and ask whether the seller is quoting a true-radius or a segmented arch, because that’s the single biggest pricing confusion we see in Miami. Call (844) 901-4551 for a free estimate with no obligation. If you have a written estimate from another company, bring it in. We’ll give you a free second opinion and tell you if you’re paying for a Porche and getting a Sentra.

Frequently Asked Questions — Custom & Geometric Windows in Miami
A custom or geometric window is any window made to a non-standard shape or size, including arches, circles, ovals, triangles, trapezoids, pentagons, and oversized rectangles that exceed manufacturer stock sizing. In Miami, custom windows often need to be impact-rated to meet Florida Building Code, which means they’re engineered and tested as a complete system. We design, order, and install these windows to match your home’s architecture and your area’s wind-load requirements.
Manufacturing typically takes 4 to 10 weeks after we finalize your design and get permit approval. Simple non-impact shaped windows trend toward the shorter end, while true-radius impact arches and oversized units take longer. The full project, from first call to final inspection, usually spans 6 to 12 weeks. We’ll give you a clear timeline before you commit, and we’ll keep you updated as the factory progresses. Call (844) 901-4551 and we can give you a realistic window based on current lead times.
Most Miami custom geometric windows run $850 to $4,500 installed, with impact-rated and oversized units at the higher end. A half-round or eyebrow arch without impact glass usually lands between $850 and $1,800. True-radius impact arches and very large units start around $3,200. Exact pricing depends on size, shape, glass, and any structural work needed at the opening. Estimates are always free and line-itemed, so you see exactly where every dollar goes.

PGT’s custom shop manufactures true-radius arches, trapezoids, and other geometric shapes with full Florida Product Approval, and we order directly, which keeps your warranty intact and your lead time honest. If you have PGT windows already and one has failed, we can also source replacement glass and hardware.
Yes, and we answer the phone 24/7. If a geometric window has broken and left your home exposed, call (844) 901-4551 any hour and a live person will pick up. We’ll talk through securing the opening, schedule a fast assessment, and get the custom replacement ordered as quickly as manufacturing allows. Full custom fabrication can’t happen overnight, but we’ll board and protect the opening properly so your home is safe while your new window is in production.
Every custom and geometric window we install includes the manufacturer’s warranty on the window itself, the glass seal, and the hardware, plus our Done Right Promise on workmanship. If we installed it and it wasn’t done right, we make it right, 100 years is a long time, and we mean it. The combination means your window is covered on materials and on labor from two directions. Ed Winslow’s name is on the door, and he stands behind every window we put in a Miami home.
Clear the interior area around the window by moving furniture at least six feet back and removing wall hangings and window treatments. Outside, trim back any landscaping that touches the wall and make sure we have a clear path to the opening. If the window is on a second story or in a hard-to-reach spot, let us know when you call so we can plan access. We handle the rest, protecting floors, managing dust, and cleaning the site when we’re done. Call (844) 901-4551 if you have questions about a specific opening before your appointment.
