AfterArched & Curved Windows in Miami Beach, FL
Arched and curved windows are custom-fabricated openings built to match a specific radius, angle, or architectural shape – no two are quite alike, and that’s exactly the point. In Miami Beach, where Mediterranean Revival facades, Art Deco detailing, and modern waterfront builds sit side by side, these windows do real aesthetic work while still needing to meet Florida’s strict impact ratings for coastal zones. At Winslow Windows & Doors, Ed Winslow has been measuring, sourcing, and installing arched and curved windows across Miami Beach since 2011 – and because every one of these units is made to order, getting the measurements right the first time isn’t optional. Call us at (863) 656-0462 anytime – a live person answers around the clock.
This page sits under our broader work with Custom & Geometric Windows in Miami Beach, which covers the full range of non-rectangular window shapes we handle. Arched and curved units are the most technically demanding of the group, so we’ve broken them out here to give you the detail you actually need before you commit to a project.
What Makes Arched and Curved Windows Different in Miami Beach
Most window replacement jobs involve a standard rectangular opening with a catalogued size. You pull the old unit, slide in the new one, and seal it up. Arched and curved windows don’t work that way. Every unit is built to a custom radius or compound curve, which means the glass, the frame, the weather stripping, and the impact laminate all have to be engineered for that specific shape as part of our Custom & Geometric Windows services.
Miami Beach adds another layer of complexity. The city sits in Miami-Dade County’s High-Velocity Hurricane Zone (HVHZ) – one of the most demanding building jurisdictions in the country. Any window installed here, regardless of its shape, has to carry a Miami-Dade Notice of Acceptance (NOA). For arched and curved units, that NOA must cover the Custom Impact Windows configuration, not just the stock product family. Installers who don’t understand that distinction will hand you a window that fails inspection – or worse, one that passes inspection on paper but fails in a storm.
Salt air is the other ongoing factor. In South Beach and along the barrier island neighborhoods, aluminum frames that aren’t properly finished oxidize faster than homeowners expect. We specify marine-grade finishes and corrosion-resistant hardware on every coastal installation, and we walk you through the maintenance schedule before we leave the job site.
When You Need Arched and Curved Window Service
- Your existing arch or fanlight is single-pane. Older Miami Beach homes – particularly the Mediterranean-style buildings near Flamingo Park and the historic districts on Espanola Way – frequently have original single-pane arched transoms that offer no real protection against wind-borne debris. Replacing them with laminated impact units brings you into code compliance without altering the look of the facade.
- The frame is showing visible corrosion or seal failure. Salt-laden air off Biscayne Bay accelerates frame degradation. If you’re seeing rust staining on aluminum, soft spots on wood frames, or fogging between the glass panes on an arched unit, the seal is gone and the insulating value is too.
- You’re renovating or adding on, and the new space has a curved or arched roofline. New construction and additions in Miami Beach often incorporate arched openings to match the existing architectural character of the building. Getting the window fabricated before the opening is finished – rather than after – saves significant rework.
- Your arched window doesn’t match your impact-rated units and you’re planning to sell. Miami-Dade home inspectors flag non-impact windows in HVHZ properties. If every other window in your home is already impact-rated but the decorative arch over your front entry isn’t, that gap will show up on a buyer’s inspection report.
- You have a casement or awning unit inside an arched frame that no longer operates correctly. Sometimes the arch is a fixed decorative frame and the operable section sits below it. When the hardware inside that assembly wears out – hinges, cranks, or multipoint locks – the whole unit can look neglected even if the glass is fine. We service the mechanical components separately when that’s the right fix.
- You want a true curved glass unit for a contemporary build or renovation. Bent or curved glass (as distinct from a flat pane set inside a curved frame) is a different product category entirely. We source curved glass units through CGI and CWS for projects where a flat-pane approximation won’t satisfy the design intent.
Our Arched and Curved Windows Process
- On-site measurement and documentation. Ed or one of our background-checked installers comes to the property and takes radius measurements, sill heights, head heights, and rough opening dimensions for every arched or curved opening on the project. We photograph the existing unit, the frame condition, and any relevant architectural details. You don’t pay for this visit – there’s no trip charge inside Miami-Dade County, and the estimate is free.
- Product selection and NOA verification. Based on your measurements, architectural style, and performance requirements, we identify the right unit from our authorized brand lineup. For curved glass applications, we typically work with CGI or CWS, both of which have product families with Miami-Dade NOAs that extend to custom configurations. We confirm the NOA covers your specific shape before anything is ordered – not after.
- Factory order and timeline communication. Custom arched and curved units are not pulled from a warehouse. Lead times from the factory run longer than stock windows – we’ll give you a realistic window (no pun intended) before you sign anything, and we stay in contact as the order progresses. If a lead time changes, you hear it from us before you find out on your own.
- Permit coordination. In Miami Beach, window replacements that alter the opening size or change the product type require a permit. We handle the permit application, submit the NOA documentation to the building department, and schedule the required inspection. You don’t have to navigate the Miami Beach Building Department on your own.
- Installation. Our uniformed, background-checked installers remove the existing unit, prepare the rough opening, and set the new arched or curved window to manufacturer specs and code. Flashing, sealant, and any required backer rod are part of the installation – not add-ons. For historic district properties near the Art Deco National Historic Landmark District, we work within the guidelines that govern visible exterior changes.
- Final inspection and walkthrough. Once the unit is in, we walk you through the operation, the hardware, and the maintenance schedule specific to your frame material and finish. The 36500-Day Done Right Promise covers every installation: if something isn’t right after we leave, we come back and fix it. That commitment doesn’t have an expiration date.
Arched and Curved Windows Pricing in Miami Beach
Arched and curved windows in Miami Beach cost more than stock rectangular units, and the honest answer is that the range is wide. A simple fixed half-round arch over a standard door opening will cost considerably less than a large eyebrow window with a compound curve and bent glass. Here are the factors that move the number, and realistic ranges based on what we see in this market.
| Unit Type | Typical Installed Cost Range (Miami Beach) |
|---|---|
| Fixed half-round or quarter-round transom (up to 36″ wide) | $650 – $1,100 per unit |
| Fixed full-arch or eyebrow unit (36″ – 60″ wide) | $1,100 – $2,200 per unit |
| Large fixed arch with impact laminate (60″+ wide) | $2,200 – $4,500+ per unit |
| Arched frame with operable casement below (combination unit) | $1,800 – $3,800 per unit |
| True bent/curved glass unit (contemporary applications) | $3,500 – $7,000+ per unit |
These ranges include the unit, installation labor, standard flashing, and sealant. Permit fees from the Miami Beach Building Department are separate and vary by project scope – we’ll include an accurate permit cost estimate in your written quote, not a vague “permit fees may apply” line.
What moves the price up: bent or curved glass vs. flat pane in curved frame; larger radius or compound curves; historic district requirements that restrict frame color or profile; second-story or difficult-access installations; removal of a deteriorated original frame that requires opening repair before the new unit can be set.
What keeps cost down: simple fixed half-round or quarter-round units; straightforward single-story access; existing frame in good condition that can accept the new unit without modification.

FAQs – Arched and Curved Windows
Do arched windows in Miami Beach have to be impact-rated?
Yes – any window installed in Miami-Dade County must comply with the High-Velocity Hurricane Zone requirements, which means the unit needs a valid Miami-Dade Notice of Acceptance regardless of its shape. This applies to decorative arched transoms, Geometric & Shaped Windows above entry doors, and full-height curved units alike. A non-impact arch in an otherwise impact-rated home creates a code violation and a genuine vulnerability in a storm. We verify the NOA for every custom configuration before placing the factory order, not after the unit arrives. Call (863) 656-0462 and we’ll pull the relevant documentation for you during a free estimate visit.
How long does it take to get a custom arched window installed in Miami Beach?
From the day you approve the order, most custom arched units take between six and twelve weeks from the factory, depending on the complexity of the shape and the manufacturer’s current production schedule. Simpler half-round transoms from CGI or CWS tend to come in on the shorter end of that range; large Oversized Openings or bent-glass units can run longer. Permit approval from the Miami Beach Building Department adds time on top of the fabrication lead – typically two to four weeks depending on current department volume. We give you a realistic total timeline upfront, and we don’t schedule your install date until we have confirmed shipping information from the factory.
Can you match an existing arched window that’s no longer available as a stock product?
In most cases, yes. We take precise field measurements of the existing opening and any surviving frame details, then work with our manufacturing partners to produce a custom unit that matches the radius, profile height, and exterior finish as closely as possible. For historic properties in the Art Deco National Historic Landmark District or other designated areas in Miami Beach, we coordinate with the Historic Preservation Board guidelines so the replacement doesn’t trigger a compliance issue. The result won’t carry the original manufacturer’s name, but it will fit the opening correctly and meet current HVHZ requirements. Call us to discuss the specifics of your existing unit before assuming a match isn’t possible.
Is it cheaper to repair an arched window or replace it?
Repair is the right call when the glass is intact, the frame is structurally sound, and the problem is limited to failed hardware, a broken seal on an insulated glass unit, or minor weather-stripping wear. Replacement makes more sense when the frame itself is corroded or rotted, when the existing unit isn’t impact-rated and you need it to be, or when the glass has cracked or the laminate has delaminated on an impact unit. The honest answer is that we won’t recommend replacement if repair is the correct fix – Ed’s name is on every job we do, and a repair that holds is better for both of us than a replacement that wasn’t needed.

Why Miami Beach Homeowners Call Winslow
There are plenty of window companies operating in South Florida, including national chains that run high-volume operations out of centralized call centers. Winslow Windows & Doors is different in a specific way: Ed Winslow has been doing this work personally since 2011, his name and license number are public, and his direct line is (863) 656-0462 – answered by a live person at any hour. That’s not a marketing claim. It’s a structural fact about how this business is run.
For arched and curved windows specifically, that accountability matters more than it does for a standard rectangular replacement. Custom units involve long lead times, permit coordination, and factory orders that can’t be reversed once they’re placed. When something changes mid-project – a fabrication delay, a permit question, a field condition that wasn’t visible in the original photos – you want to talk to someone who has skin in the outcome, not a ticket system.
Our 36500-Day Done Right Promise covers every installation we do. If it isn’t right, we come back and make it right. No expiration date on that, no exceptions for custom units, no fine print that carves out arched windows because they’re complicated. Done right means done right.
From the waterfront condos along Collins Avenue to the restored Mediterranean houses in the Flamingo Park neighborhood, we’ve measured and installed arched windows in buildings that demand precision. We’re authorized to install ECO Window Systems and ES Windows products alongside CGI and CWS, which means we have access to a broader product range than most local competitors when a specific shape or performance spec requires it.

If you have an arched or curved window that needs replacing, repairing, or specifying from scratch, call (863) 656-0462. The estimate is free, there’s no trip charge inside Miami-Dade County, and you’ll talk to a real person who can answer a real question. That’s how Winslow Windows & Doors has worked since day one.
