AfterGeometric & Shaped Windows in Miami, FL
Custom & Geometric Windows - circles, octagons, arches, trapezoids, and custom angles - are specialty units built to exact dimensions and installed to perform just as reliably as any standard rectangle. In Miami, where hurricane-rated glazing is required by code and salt air never takes a day off, getting these shapes done right means more than aesthetics: it means impact-rated glass, precision frames, and a proper weatherseal that holds through a Category 4 storm. If you’re replacing an aging palladium above your front door or adding an accent oval to a Brickell high-rise unit, Winslow Windows & Doors has handled those calls since 2011, and Ed Winslow’s name is on every one of them.
We’re locally owned and owner-operated – not a franchise routing your job to whoever’s available that week. Call us at (863) 946-5039 and a live person answers, any hour of the day. From there, we measure, source from our authorized brand lineup, pull any required permits, and install with the 36500-Day Done Right Promise backing every square inch of the work. You can read more about our full approach on the Custom & Geometric Windows in Miami page, but this page focuses specifically on shaped and geometric units – what drives the cost in Miami’s market, how the process works, and what to watch out for.
When You Need Geometric & Shaped Windows
Shaped windows don’t fail on a predictable schedule, but Miami’s climate accelerates the timeline. Salt air corrodes aluminum frames from the inside out, and the thermal cycling between a 95-degree July afternoon and an aggressively air-conditioned interior stresses seals that were already marginal. Here’s when homeowners in Miami typically call us:
- Your existing shaped window no longer passes a blow-door test or shows daylight around the frame. In older Coral Gables and Coconut Grove homes, we regularly find arched or circular windows that were installed before Miami-Dade’s post-Andrew impact code and have never been upgraded. A failed seal on a shaped unit is more than an energy bill problem – it’s a code liability during permit inspections for any subsequent work.
- Condensation is forming inside the glass layers. Dual-pane shaped windows that fog between the panes have a broken insulated glass unit. In Miami’s humidity, that fogging typically worsens within one rainy season; the glass won’t clear on its own.
- You’re remodeling a Mediterranean Revival or Art Deco home and need a shaped window to match the architecture. Neighborhoods like El Portal, Miami Shores, and parts of Little Havana have heavy concentrations of 1920s-1950s homes where the original window shapes are part of the building’s character. Matching those shapes exactly requires custom fabrication, not off-the-shelf stock.
- Your builder or architect spec’d a geometric accent window for a new addition or ADU. New construction in Miami requires impact glazing across the board; a fixed geometric unit above a door or in a gable end still has to meet Miami-Dade’s Notice of Acceptance (NOA) requirements.
- A post-storm inspection flagged your specialty window as damaged or non-compliant. After major storms, Miami-Dade County’s inspection process can flag shaped windows – particularly older decorative glass units in Wynwood lofts or Doral townhouses – that no longer meet current standards.
- You want to add a geometric window where none existed before. Opening a new rough opening in an existing wall for a circle, arch, or polygon window involves structural work, framing, and waterproofing. It’s not a weekend project, and in Miami’s high-humidity envelope, improper flashing on a shaped opening creates rot pathways that can compromise the surrounding wall within two or three wet seasons.
Our Geometric & Shaped Windows Process
Custom shapes require more coordination than a standard rectangle swap. Every step below matters, and skipping any one of them is how shaped windows end up leaking or failing inspections.
- On-site measurement and documentation. We come to your Miami address, measure the rough opening in multiple planes, and photograph the existing condition. For arches, this includes measuring the radius precisely – a half-inch error on a 48-inch arch translates into a visible gap at the apex. For polygons and custom angles, we capture every corner angle. This isn’t something we eyeball; it determines the fabrication template.
- Miami-Dade NOA review and product matching. Not every shaped window product carries a Miami-Dade Notice of Acceptance. We cross-reference your opening’s size, shape, and exposure category against our authorized brands – ES Windows and ECO Window Systems both offer custom-shape impact units with valid NOAs for Miami-Dade – and confirm that the product we specify is fully compliant before we order anything.
- Permit filing (when required). Replacement-in-kind on a shaped window often requires a permit in Miami-Dade County, especially if the glazing type is changing (from non-impact to impact, or from single-pane to insulated). We handle the permit application. You don’t have to track it. We won’t let your job sit in a limbo where work has started but permits haven’t posted.
- Factory fabrication and delivery coordination. Custom shapes are built to order. Lead times for shaped impact windows through our authorized channels typically run three to five weeks from order to delivery, depending on the complexity of the shape and current shop schedules. We give you an honest timeline at the start – not an optimistic guess that shifts every week.
- Installation and weatherproofing. Our background-checked, uniformed technicians install the unit into the prepared opening, set it in the correct plane, apply the Miami-Dade-specified flashing and sealant, and secure the frame to the rough opening per the NOA’s fastener schedule. For arched or curved units, this takes longer than a standard installation because each fastener position has to follow the curve of the frame precisely. We don’t rush it.
- Inspection sign-off and final walk-through. After installation, we coordinate the required inspection with the building department. Once the inspector signs off, we walk you through the finished window – how it looks from the inside, how it looks from the exterior, and what the 36500-Day Done Right Promise covers going forward. If anything doesn’t look right at the walk-through, we address it before we leave.
Geometric & Shaped Windows Pricing in Miami
Shaped and geometric windows cost more than standard rectangles of the same approximate size, and the difference is real. Custom fabrication, longer lead times, more complex installation, and Miami-Dade NOA compliance all add to the base cost. Here’s what the Miami market looks like as of 2025-2026:
| Window Type | Typical Miami Price Range (supply + install) | Notes |
|---|---|---|
| Fixed arch or half-circle (up to 36″ wide) | $480 – $850 | Most common shape in Miami’s Mediterranean Revival homes |
| Fixed arch or half-circle (36″ – 60″ wide) | $750 – $1,400 | Larger radius increases fabrication cost |
| Full circle or oval (fixed) | $600 – $1,200 | Diameter and frame profile affect pricing |
| Octagon or polygon (fixed) | $550 – $1,100 | Corner count and size both factor in |
| Trapezoid or custom angle (fixed) | $520 – $1,050 | Common in contemporary Doral and Kendall new builds |
| Palladian combination (arch over rectangle) | $900 – $2,200 | Multi-unit combination; framing and sill work included |
These ranges assume impact-rated laminated glass with a valid Miami-Dade NOA – non-impact glass is not a realistic option for exterior windows in Miami-Dade County for most applications. Permit fees, if required, typically run $75 to $200 depending on the municipality. If you’re in an HOA-governed community in Doral, Kendall, or South Miami, factor in potential architectural review timelines; we can advise on what documentation your HOA typically wants.
What moves the price up within these ranges: larger dimensions, thicker impact glass, specialty finishes on the aluminum frame, a more complex shape with more corner angles, and whether we’re removing and disposing of a single-pane unit that’s been painted or caulked into the opening over decades. What keeps it toward the lower end: simpler shapes, smaller dimensions, straightforward access, and a rough opening that’s already correctly sized and structurally sound.

FAQs – Geometric & Shaped Windows
Do geometric and shaped windows in Miami have to be impact-rated?
Yes, in nearly all cases. Miami-Dade County’s building code requires impact-rated glazing on exterior windows, including fixed geometric and shaped units, for new installations and replacements in the county’s High Velocity Hurricane Zone. The specific product you install must carry a Miami-Dade Notice of Acceptance (NOA) that covers your window’s size, shape, and wind-load exposure category. A shaped window without a valid NOA will not pass final inspection. We only source and install products with current NOA coverage for Miami-Dade, so this isn’t a risk you take with us. Call (863) 946-5039 and we can confirm compliance for your specific opening during the estimate.
How long does it take to get a custom-shaped window made and installed in Miami?
From signed contract to installation day, most Oversized Openings and custom geometric windows run four to seven weeks in the current Miami market. The fabrication window from our authorized suppliers is typically three to five weeks, and permit processing in Miami-Dade adds one to two weeks on top of that, depending on the jurisdiction (City of Miami, Miami-Dade unincorporated, Coral Gables, and other municipalities each have their own counters and timelines). We give you the realistic schedule on day one – not a number we’ll revise three times before the truck shows up. Call (863) 946-5039 if you’re working against a renovation deadline; we can tell you immediately whether the timeline is feasible.
Can you match a shaped window to the original style in a historic Miami home?
Yes, and this is work we do regularly in Coral Gables, Miami Shores, and El Portal, where Spanish Mission, Mediterranean Revival, and Art Deco architecture means a lot of Arched & Curved Windows, elliptical, and multi-sided openings. Through our authorized brands – including ECO Window Systems, which produces custom-profile aluminum frames – we can get very close to an original profile while upgrading the glass to current impact standards. We’ll photograph and measure the existing unit before ordering anything. Where a historic district has design-review requirements, we can provide product specifications and NOA documentation to support your submission. The result is a window that looks like it belongs to the house and performs like it was built for a Category 4 storm. Call (863) 946-5039 to schedule a measurement visit.
Is it cheaper to repair a failing shaped window or replace it entirely?
Repair is usually only cost-effective when the frame is structurally sound and the issue is limited to the glass unit itself – for example, a broken seal on a dual-pane insert in an otherwise solid arch frame. In that case, replacing just the insulated glass unit (IGU) typically runs $150 to $350 for a shaped piece, depending on size and glass spec. But if the frame is corroded, the sealant has failed around the perimeter, or the product lacks a current Miami-Dade NOA, replacement is the better path – because a repaired non-compliant window still won’t pass inspection and will likely fail again within a few seasons in Miami’s salt-air environment. We’ll tell you honestly which direction makes sense after we’ve looked at your specific window. Call (863) 946-5039 for a free estimate and a straight answer.
Why Miami Homeowners Call Winslow for Shaped Windows
Ed Winslow started this company in 2011, and geometric windows have been part of the work from the beginning. Miami’s housing stock – Spanish colonials in Coral Gables, contemporary towers in Brickell, 1950s CBS homes in Hialeah – produces shaped-window jobs that require actual experience, not a crew that does rectangles all week and figures out the arch on the way there.
Every technician we send to your home in Miami is background-checked and arrives in uniform. You’ll know who to expect before the truck pulls up. We carry the state license and insurance you should always ask for before letting anyone touch your windows – Ed’s published license number isn’t buried in a footer, it’s part of how we introduce ourselves. And when the job is done, it’s covered by our 36500-Day Done Right Promise: if it’s not right, we come back and make it right. No asterisks, no expiration date on that commitment.
We’re authorized to install products from eight brands, including ES Windows and ECO Window Systems, both of which produce impact-rated custom shapes with Miami-Dade NOA coverage. Mr-Glass is in our lineup for specialty glass configurations where standard stock shapes don’t apply. You get product options, not a single manufacturer’s catalog.
And when you call us at any hour – 2 a.m. because you just noticed your oval window has a crack after a storm, noon on a Saturday, whenever – a real person answers. Not a voicemail. Not a callback form. A person who can pull up your address, check your job history, and give you a straight answer about next steps.
Ed’s name is on the door, and on every job we do in Miami. That’s the accountability a national chain simply can’t offer. We’re not the company with the biggest billboard on I-95. We’re the one down the road.
