AfterArched & Curved Windows in Miami, FL
Arched and curved windows in Miami can be replaced or installed to match your home’s exact radius and profile with our Custom & Geometric Windows services, impact-rated and energy-certified for South Florida’s climate. Most projects move from measurement to finished installation in two to four weeks, depending on glass type and frame complexity. If you have a Palladian arch over your foyer, a semicircle transom above a front door, or a full eyebrow window along a roofline, Winslow Windows & Doors has handled that exact shape – and Ed Winslow’s name goes on every one of those jobs.
We’ve been doing this in Miami since 2011. Call us at (863) 946-5039 – a live person answers every call, 24 hours a day, seven days a week, no voicemail loops. If you’re still figuring out what you need, our Custom & Geometric Windows in Miami page gives you the full picture of non-rectangular window shapes we work with across South Florida.
When You Need Arched or Curved Windows
Not every window problem announces itself with a crack or a draft. With arched and curved windows, the signs can be subtler – and ignoring them in Miami’s heat and humidity tends to make things worse faster than it would anywhere else.
- Hurricane season is coming and your arched windows aren’t impact-rated. Miami-Dade County enforces some of the strictest wind-load codes in the country, and non-impact glass in an arch above a front entry creates a genuine vulnerability. We regularly see homes in Coconut Grove and Coral Gables with beautiful original arched transoms that have never been upgraded – the frame looks fine, but the glass isn’t meeting current Miami-Dade NOA standards.
- Condensation is forming inside the glass unit. When the sealed air space between panes fails, you get fogging that won’t wipe away. On a curved insulated glass unit, that seal failure is harder to spot early because the condensation pools along the bottom radius – by the time it’s obvious, the unit has usually been compromised for months.
- Your existing arch frame is warped, cracked, or has visible daylight gaps. Wood and lower-grade vinyl frames don’t hold their shape well in Miami’s heat. A warped arched frame lets conditioned air escape at the curved seam – often the highest point in a room – and that’s where your air conditioning dollar disappears first.
- You’re renovating or building and need a custom radius fabricated from scratch. Spec homes in Brickell, Pinecrest, and South Miami often call for arched windows that don’t come off any standard shelf. We take field measurements and work with manufacturers like ES Windows and ECO Window Systems who build to custom radii rather than forcing a standard shape to fit.
- Your current arch window is single-pane clear glass. Single-pane glass in a Miami arch contributes meaningfully to solar heat gain, especially on east- and west-facing elevations. Switching to a low-E laminated impact unit in that same arch opening cuts solar heat transmission and keeps your interior noticeably cooler without touching the architectural character of the window.
- The frame finish has oxidized, chalked, or peeled and repainting isn’t keeping up. Saltwater air accelerates finish degradation on aluminum frames, particularly on homes within a mile of the bay or the Atlantic. When the frame looks bad but the glass is still sealed, sometimes recapping is an option – but when both are gone, a full replacement is usually the smarter long-term call.
Our Arched and Curved Window Process
Custom shapes require more precision than rectangular windows at every single stage. Here’s exactly how we handle a typical arched or curved window project in Miami – from the first conversation to the day we pull the truck out of your driveway.
- On-site field measurement and shape documentation. We don’t ask you to measure your own arch. One of our uniformed, background-checked technicians comes to your home, takes radius measurements at multiple points along the curve, documents the existing frame condition, and photographs the rough opening. Arches aren’t always perfectly symmetrical, especially in older Miami homes, and we account for that before anything gets ordered. There’s no trip charge for this visit inside Miami-Dade County.
- Product selection and Miami-Dade compliance review. We walk you through glass options and frame materials that are right for your specific opening and your home’s elevation – factoring in Miami-Dade NOA requirements, your insurance carrier’s preferences, and your energy goals. We work with ES Windows and ECO Window Systems for custom-radius impact units, and we’ll tell you plainly what each option costs and what you’re getting for it. Upfront pricing. No surprises on the invoice.
- Custom fabrication order and lead-time confirmation. Once you approve the quote, we place the fabrication order with confirmed dimensions. Custom arched and curved units typically carry a two-to-three-week lead time from manufacturers. We give you a realistic timeline on day one and update you when the product ships – you won’t be chasing us for a status update.
- Permit filing where required. Miami-Dade County requires a permit for window replacements that change the opening size or involve structural changes to the rough opening. For same-size replacements that maintain the existing opening, permit requirements vary. We handle permit filing when it’s required and keep the paperwork moving so it doesn’t stall your project.
- Installation day: removal, prep, and set. We remove the existing unit carefully – paying attention to interior trim, surrounding stucco, and any decorative casing that’s worth preserving. The rough opening gets inspected for moisture damage, especially at the sill and along the curved header. We flash, seal, and set the new unit to manufacturer specs and Miami-Dade code. Curved frames require precise shimming at multiple points along the radius – skip that step and the frame will rack over time.
- Final inspection, cleanup, and walkthrough. We test every operable unit, inspect the seal perimeter, clean the glass inside and out, and walk you through what was done and why. If anything isn’t exactly right – a gap, a finish issue, an operation problem – we fix it before we leave. That’s not a policy; it’s the 36500-Day Done Right Promise. If it’s not done right, we come back and make it right. That commitment doesn’t expire.
Arched and Curved Window Pricing in Miami
Arched and curved windows in Miami cost more than standard rectangles – that’s a straightforward fact, and we’d rather tell you upfront than let you find out after you’ve signed something. The added cost comes from custom fabrication, more complex installation, and the Custom Impact Windows glass that Miami-Dade code requires for most residential openings.
Here are honest ranges for the most common project types we handle in Miami:
| Window Type | Typical Installed Price Range |
|---|---|
| Semicircle transom (non-operable, impact glass, up to 36″ wide) | $850 – $1,400 |
| Full Palladian arch unit (fixed arch + operable side lites, impact-rated) | $1,800 – $3,200 |
| Eyebrow or elliptical window (custom radius, impact glass) | $1,100 – $2,200 |
| Large curved picture window (60″+ width, impact, custom radius) | $2,400 – $5,000+ |
| Arch-top casement (operable, impact-rated, aluminum or vinyl frame) | $1,200 – $2,600 |
What moves the price up or down
- Radius complexity: A true semicircle is easier to fabricate than an asymmetrical ellipse or an eyebrow with a compound curve. The more complex the shape, the higher the fabrication cost.
- Glass package: Standard impact laminated glass is the floor. Adding low-E coatings, tinted interlayers, or high-performance PVB laminates adds cost – and in Miami’s sun, those upgrades pay back in lower cooling bills over time.
- Frame material: Aluminum frames handle Miami’s humidity and salt air better than most alternatives and tend to hold their profile over time. Premium aluminum with thermal break costs more upfront than basic extruded aluminum, but performs better long-term in South Florida’s climate.
- Rough opening condition: If we open the wall and find rotted framing, compromised lintels, or moisture-damaged stucco around the arch, that work gets done before the new window goes in. We quote that separately and honestly – it’s not a line item we bury.
- Floor and accessibility: A first-floor arch over a front door is a straightforward setup. A curved window on the second or third story of a Brickell high-rise or a Coral Gables two-story adds staging and labor time.

FAQs – Arched and Curved Windows in Miami
Can arched windows in Miami be impact-rated?
Yes – impact-rated arched and curved windows are fully available and are what Miami-Dade County code requires for most residential projects. Manufacturers like ES Windows and ECO Window Systems fabricate custom-radius impact units to any approved shape, using laminated glass that meets Miami-Dade NOA standards. The glass holds together under impact rather than shattering, which is what the code is designed around. If you have an existing arch with non-impact glass, replacing it with a compliant impact unit is typically straightforward as long as the rough opening and frame are in reasonable condition. Call (863) 946-5039 and we can tell you what your specific window will need.
How long does it take to replace an arched window in Miami?
Most arched window replacements in Miami take two to four weeks from signed contract to completed installation. The majority of that time is fabrication lead time at the manufacturer – once the custom unit arrives, installation of a single arch transom or Palladian window typically takes one day on-site, sometimes less. Larger or more complex projects, or jobs requiring permits, can run closer to five or six weeks. We give you a realistic timeline on day one and don’t adjust it without telling you why. If you’re working toward a specific date – a closing, a renovation deadline, a storm season window – tell us upfront and we’ll structure the schedule around it.
Do curved windows need a permit in Miami-Dade County?
It depends on the scope. In Miami-Dade County, window replacements that change the size of the opening or involve modifications to the structural framing around an arch typically require a permit. Like-for-like replacements in the same opening, using Miami-Dade NOA-approved products, may qualify for a permit exemption under certain conditions – but that determination is made based on your specific home, the opening, and the product being installed. We handle permit filing when it’s required, and we tell you whether your project triggers it before we start. You don’t have to guess or call the county yourself.
Is it possible to change the shape of an existing arched window opening?
Changing the shape of an arch opening is structural work – it involves modifying the rough opening, potentially the lintel or header above it, and the surrounding stucco or cladding. It’s possible, and we’ve done it in Miami on renovation projects where a homeowner wanted to replace a standard rectangular opening with a true arch, or convert a smaller transom into a full Palladian unit with Geometric & Shaped Windows. It adds cost and almost always requires a permit. If that’s what you’re considering, the conversation starts with an on-site measurement visit so we can see what the wall is actually doing – call (863) 946-5039 and we’ll set that up at no charge inside Miami-Dade County.
Why Miami Homeowners Call Winslow for Curved and Arched Windows
Miami’s building stock is genuinely different from the rest of Florida. You have Mediterranean Revival homes in Coral Gables with original cast-stone arch surrounds. You have 1980s and 1990s spec homes in Kendall and Doral where the arched transoms were decorative afterthoughts – and they’re showing their age. You have newer construction in Brickell and Edgewater where the architect specified Oversized Openings with a curved curtain element that has to perform at high-wind category loads. All three of those situations look different on paper, and they call for different solutions in the field.
What ties them together is that none of them is a job for someone reading a measurement off a standard order form. Custom arched and curved windows require someone who shows up, measures the actual opening, accounts for the irregularities that always exist in older Miami construction, and orders the unit that fits what’s actually there – not a close approximation.
