Arched & Curved Windows in Miami, FL

Arched and curved windows are our Custom & Geometric Windows services – measured, ordered, and installed to fit a specific shape that no off-the-shelf unit can match. In Miami, where Mediterranean Revival, Art Deco, and modern coastal architecture all share the same zip codes, these windows are more common than most homeowners realize, and replacing or upgrading them takes a different skill set than a standard rectangle swap. At Winslow Windows & Doors, Ed Winslow has been fitting arched and curved units across Miami since 2011, and we bring that same owner-led accountability to every curved sill and radiused frame we touch. Call us at (863) 862-5435 – a live person answers around the clock, no voicemail, no callback queue.

If you’re exploring the full range of specialty shapes we handle, our Custom & Geometric Windows in Miami page covers every angle – from octagons and trapezoids to the true radius work described here. This page is specifically about arched and curved windows: what they cost in Miami’s market, what the installation process looks like, and why the details matter more here than almost anywhere else in Florida.

Quick answer: Arched and curved window replacement in Miami typically runs between $650 and $2,800 per unit depending on size, glass type, and whether the opening requires structural modification. Most single-unit jobs are completed in one day once the custom unit arrives from the fabricator, which usually takes two to four weeks.

When You Need Arched & Curved Windows

• Your existing arched unit is fogged, cracked, or leaking at the frame. In Miami’s humidity, the seal between the curved glass and the frame degrades faster than on flat windows. Once you see condensation trapped inside the glass or water staining on the interior sill, the insulated glass unit has failed and the frame is likely compromised too.
• You’re upgrading to impact glass and your current arch isn’t rated. Many Coral Gables and Coconut Grove homes built before the 2002 Florida Building Code changes still have decorative arched transoms with single-pane glass. Those units will not pass a Miami-Dade NOA (Notice of Acceptance) inspection and need to be replaced before a sale or after any significant storm claim.
• The opening was custom-built and no stock window fits it. True radius windows – where the entire frame curves, not just the top – require a custom fabrication order. If a previous contractor patched yours with caulk or a flat panel insert, you know it, and so does anyone who looks at it from the street.
• You’re adding an arched window to a new addition or renovation. New construction in Brickell, Edgewater, and the Roads neighborhood frequently incorporates arched transoms above entry doors or in great rooms. Getting the rough opening framed correctly and the custom unit ordered in sequence with the rest of the project saves weeks of delay.
• Your current arch lets in excessive heat. South-facing arched windows on Miami homes can contribute significantly to cooling costs because the curved glass surface – often a single large pane – has more solar exposure than a divided flat window. Low-e coatings and argon-filled impact glass make a measurable difference in rooms that currently overheat by midday.
• The frame is rotting or the casing has separated from the wall. Wood frames around arched windows in Miami’s salt air environment tend to fail at the curve first, where water pools between the frame and the wall. If you’re seeing paint bubbling, soft spots when you press the casing, or daylight at the joint, the frame needs to come out – not just be patched.

Our Arched & Curved Windows Process

1. On-site measurement and opening assessment. Curved windows are unforgiving of approximation. We measure the full radius or ellipse at multiple points, check the rough opening for level and plumb, and look at the surrounding wall for any structural concerns before we order anything. In older Miami homes – especially the CBS construction common in Little Havana and West Miami – the opening may have settled unevenly over decades. We identify that before it becomes a problem mid-install.
2. Custom unit selection and fabrication order. Based on your measurements, structural needs, and energy goals, we specify the unit. For impact-rated arched windows, we work with manufacturers like ES Windows and ECO Window Systems, both of which produce Miami-Dade NOA-approved curved and arched configurations. The fabrication lead time is typically two to four weeks. We give you a firm timeline at the order date, not a vague estimate.
3. Permit coordination. In Miami, window replacement – including arched units – generally requires a building permit when the work involves structural changes or when the new window changes the opening size. We handle the permit application and coordinate with Miami-Dade Building Department on your behalf. You won’t be left managing paperwork between a fabricator, a permit office, and a contractor.
4. Frame removal and opening preparation. The existing frame comes out carefully to preserve as much of the surrounding stucco and interior finish as possible. If the rough opening needs modification – shimming, framing adjustment, or repair of rotted substrate – we do it before the new unit goes in. Skipping this step is how water infiltration problems start over.
5. Installation and weatherproofing. The new arched or curved unit is set, leveled, and fastened per Miami-Dade product approval specifications. Flashing, sealant, and any required stucco patching are completed the same day. We don’t leave a half-finished opening overnight – not in a city where an afternoon thunderstorm is a near-daily event from June through October.
6. Final inspection and walkthrough. We walk you through the finished installation, show you the operation (if the unit opens), point out the sightlines from inside and outside, and confirm the permit inspection is scheduled. If anything doesn’t meet our standard – or yours – we address it before we leave. That’s the 36500-Day Done Right Promise in practice, not in a brochure.

Arched & Curved Windows Pricing in Miami

Arched and curved window pricing in Miami spans a wide range because the variables are wide. A small fixed transom arch above an interior door is a fundamentally different project than a full-height curved picture window on a Coconut Grove waterfront property. Here’s how costs break down in our market:

Several factors push a job toward the higher end of those ranges. Glass upgrades matter: laminated impact glass with a low-e coating costs more than standard clear impact glass, but it pays back in lower FPL bills over time. Frame material matters too – aluminum frames are the Miami standard for salt-air durability, but some homeowners in historic districts choose fiberglass or clad-wood for appearance, and both carry a premium. And opening complexity matters most of all: an arch that’s been patched, widened, or isn’t square adds labor that we identify upfront in our walkthrough, not as a line item surprise after the work is done.

Upfront pricing is not a marketing phrase for us – it’s how we operate. You get a written number before any work starts. We also offer $40 off any repair over $200, a 10% discount for seniors and veterans (permanent, not a promotion), and no trip charge for homes inside our home county. If you’ve already gotten a written estimate from another contractor, we’ll give you a free second opinion on it – no obligation.

Why Miami’s Climate Makes Arched Window Installation Different

Miami’s coastal environment is harder on windows than almost any other market in the continental United States. Salt air accelerates frame corrosion, particularly at the curved sections of arched units where water tends to sit. High humidity causes wood substrates to swell and shift, which can rack a curved frame out of tolerance over time. And the annual hurricane season – which Miami-Dade takes seriously enough to require Custom Impact Windows on most replacement work – means that a beautiful arch with single-pane glass is both a code violation and a genuine safety concern.

We see specific patterns in different parts of Miami. In Hialeah and Westchester, older CBS homes often have arched openings that were never designed for modern impact glass weights, so the rough framing needs reinforcement. In Brickell and Edgewater condos, arched windows in common areas or penthouse units are governed by building-specific approval requirements that layer on top of Miami-Dade code. In Coral Gables, the historic preservation rules add another review step before any exterior change – including a window swap – can be finalized. We know these variations because we’ve worked in all of them.

ES Windows, one of the manufacturers we’re authorized to install, produces impact-rated arched configurations specifically tested for the Miami-Dade wind load requirements. ECO Window Systems similarly offers custom curved units with current NOA documentation. Having a manufacturer relationship means we can get accurate lead times, confirm product specs before the order goes in, and stand behind the unit if something is wrong with the fabrication – not pass you back to a 1-800 number.

Arched Windows and Miami-Dade Code: What Homeowners Should Know

Miami-Dade County has some of the strictest window code requirements in the country, and arched windows sit in a specific regulatory space. Any replacement window in a permitted scope of work needs a current Notice of Acceptance (NOA) from Miami-Dade Product Approval. For custom arched and curved units, this means the manufacturer must have tested that specific configuration – not just a similar flat window – and received approval for it.

Not every manufacturer can provide this. It’s one reason why we limit our arched window work to brands with proven Miami-Dade documentation. An arched window installed with an out-of-county or unapproved product can fail a permit inspection, create complications at property sale, and – more importantly – may not perform as expected in a named storm. We check the NOA before the order goes in, every time.

Permit requirements for arched window replacement in Miami-Dade generally apply when the work involves structural changes, when the unit type changes (single-pane to impact, for example), or when the project is valued above a certain threshold. We pull the permit, coordinate the inspection, and close it out. You don’t need to manage that process – that’s our job.

FAQs – Arched & Curved Windows

Can an arched window be impact-rated in Miami?

Yes, impact-rated arched windows are available and required for most replacement work in Miami-Dade County. The key is that the specific arched configuration – not just a comparable flat window from the same manufacturer – must carry a Miami-Dade Notice of Acceptance (NOA). Manufacturers like ES Windows and ECO Window Systems produce Geometric & Shaped Windows with current NOA documentation that meets Miami-Dade’s wind load standards. We verify the product approval before placing any order. Call (863) 862-5435 if you want to confirm whether your specific opening qualifies for an impact-rated replacement – the estimate is free.

How long does it take to get a custom arched window in Miami?

Custom arched and curved windows typically have a fabrication lead time of two to four weeks from the confirmed order date. That timeline covers manufacturing the unit to your specific radius measurements. Installation itself usually takes one day once the unit arrives and the permit is in hand. The permit application process in Miami-Dade can run one to three weeks for residential window work, so we submit it early in the process to avoid stacking delays. Total project timeline from initial measurement to completed installation is typically four to seven weeks for a straightforward single-unit job.

Will replacing my arched window affect my homeowner’s insurance in Miami?

Upgrading from non-impact to impact-rated arched windows in Miami-Dade often qualifies for a homeowner’s insurance premium reduction under Florida’s windstorm mitigation credit program. The reduction varies by insurer and by how many openings are upgraded, but homeowners who complete a full opening protection upgrade – including arched units – sometimes see meaningful annual savings. We provide a product approval document and installation record that your insurance carrier can use to update your wind mitigation rating. Your insurer or a licensed wind mitigation inspector can give you specific credit figures based on your policy.

What’s the difference between an arched window and a curved window?

An arched window has a flat bottom section with a curved or semi-circular top – the arch is at the top of the frame and the rest of the unit is rectangular. A curved window has a frame that curves along its entire height or width, creating a true radius rather than a combination of straight and curved sections. Oversized Openings like curved windows are less common and generally more expensive to fabricate because the entire glass surface and frame must follow the radius. Both types require custom fabrication – neither comes off a standard production line. We handle both configurations, and the on-site measurement appointment will confirm exactly which type you have and what a replacement involves.
