AfterArched & Curved Windows in Coral Gables, FL
Our Custom & Geometric Windows services in Coral Gables can be measured, fabricated, and installed to match your home’s exact opening – whether that’s a classic half-round transom above a front door or a full elliptical unit spanning a two-story foyer. Most projects take one to three weeks from measurement to installation, and every unit we install is impact-rated to meet Miami-Dade’s stringent NOA requirements. If you’re replacing an existing arched window or adding one to a new opening, call (904) 478-8983 and a live person will pick up – any time of day.
Coral Gables is one of the few places in South Florida where the architecture genuinely demands this kind of precision work. The Mediterranean Revival homes along Alhambra Circle, the Spanish Colonial estates near Coral Way, and the newer custom builds in Cocoplum all share one thing: Geometric & Shaped Windows that flat, rectangular glass simply can’t serve. These openings aren’t decorative afterthoughts. They’re structural, they’re on the building permit, and they have to be impact-rated. Getting them wrong means a failed inspection and a window that leaks every time a tropical storm tracks through Biscayne Bay.
We’ve been doing this kind of work in Coral Gables since 2011. Ed Winslow built this company on jobs that other contractors turned away because the radius was too tight or the transom too wide. That’s exactly where we specialize. If you want to see the full range of shaped glass work we offer, our Custom & Geometric Windows in Coral Gables page covers the broader category – arched and curved units are the most common request we handle within it.
When You Need Arched or Curved Window Service in Coral Gables
- Your existing arched window is leaking or fogged. Failed seals in an insulated arched unit are common in Coral Gables homes that went through the 2004-2005 hurricane seasons with original windows still in place. The curved glass shifts slightly with thermal cycling, and if the original glazing compound was petroleum-based (common in pre-2000 installs), it hardens and pulls away from the frame long before the glass itself fails.
- You’re renovating a Mediterranean Revival or Spanish Colonial home. Building permits in Coral Gables require any replacement window to match the approved architectural character of the structure. A square replacement in an arched opening will fail city review. We produce units that match the original radius and profile so your permit closes without a callback.
- Your current arched unit is single-pane and not impact-rated. Miami-Dade code has required impact-rated glazing in wind-borne debris regions since 2002. Many older Coral Gables homes – particularly in the Biltmore and Granada sections – still have original single-pane arched transoms that are both a code liability and an energy drain. Replacing them cuts both risk.
- You’re adding a new arched opening to an existing wall. Some homeowners in Cocoplum and Old Cutler Road want the look of a classic arched window in a room that currently has a rectangular opening. This involves structural work and a Miami-Dade permit, and the window itself must be custom-fabricated. We coordinate both.
- The frame is visibly warping or the sash won’t seat properly. In Coral Gables’ humidity and salt-air environment, aluminum frames on arched units can develop stress corrosion, especially on homes within a half-mile of Biscayne Bay. A warped frame on a curved window isn’t a DIY fix – the geometry means even a millimeter of deviation changes how the glass loads under wind pressure.
- You’re preparing for a major storm season and want full code compliance. FEMA flood maps updated in 2023 reclassified several Coral Gables neighborhoods, and insurance underwriters are paying closer attention to window certifications. An arched window without a current NOA label can affect your Citizens or private carrier premium. We document every unit we install with the full NOA package.
Our Arched & Curved Windows Process in Coral Gables
- On-site measurement and radius verification. Arched windows fail when they’re ordered from a rough measurement. We send a technician to Coral Gables with a radius gauge and a digital template tool. We measure the sill, both jambs, the spring point of the arch, and the rise at the crown. For elliptical or eyebrow units, we take a physical template using a flexible rod and transfer it to a CAD file. This step takes 45-60 minutes and it’s what separates a window that fits from one that has to be returned.
- Permit application and Miami-Dade NOA confirmation. Before we order glass, we pull the permit with the City of Coral Gables Building Department and confirm the NOA for the specific unit being installed. Coral Gables has its own architectural review layer on top of Miami-Dade county requirements, and some historic districts require an additional sign-off. We handle this paperwork – you don’t have to make a single call to the city.
- Custom fabrication through our authorized brand partners. Depending on the opening size, radius, and impact rating needed, we order through CGI or ES Windows – both of which offer factory-fabricated arched units in aluminum and PVC frames with laminated impact glass. Lead times run 7-21 days depending on the profile. We’ll give you an exact window (no pun intended) when we place the order.
- Pre-installation rough-in inspection. Before the window arrives, we check the rough opening for moisture intrusion, rot in any wood buck material, and proper flashing. In Coral Gables, stucco exteriors often hide water damage that’s been migrating behind the frame for years. Catching it before the new window goes in saves you from doing this job twice.
- Installation, sealing, and glazing. We set the unit, fasten it to the buck or masonry per the approved permit drawings, apply a continuous bead of weatherization sealant, and install the impact-rated glazing. For arched units, the curved geometry means the sealant work is done by hand in sections – no mechanized caulk gun can follow a tight radius consistently. Our technicians are background-checked and show up in uniform, so you know exactly who’s working on your home.
- Final inspection and Done Right sign-off. We schedule the city inspection, walk it through with the inspector, and hand you the closed permit card. Then Ed Winslow’s name goes on the job under the Done Right Promise: if anything we installed isn’t performing correctly, we come back and make it right. That’s not a warranty with a call center behind it – it’s a promise from the person who built this company.
Arched & Curved Windows Pricing in Coral Gables
Arched and curved window pricing in Coral Gables runs higher than standard rectangular units because every piece involves custom fabrication – there’s no off-the-shelf radius that fits every opening. Below are honest ranges based on the jobs we actually do in this market. These are installed prices including labor, permit, and disposal of the old unit.
| Window Type | Typical Installed Price Range |
|---|---|
| Half-round transom (up to 36″ wide) | $480 – $850 |
| Half-round transom (37″ – 60″ wide) | $850 – $1,400 |
| Full arched unit with operating sash | $1,200 – $2,400 |
| Elliptical or eyebrow window | $1,400 – $2,800 |
| Quarter-round corner unit | $600 – $1,100 |
| Multi-piece curved assembly (foyer or stairwell) | $2,800 – $6,500+ |
Several factors push a job toward the higher end of these ranges in Coral Gables specifically:
- Historic district review fees. Homes in the platted historic sections of Coral Gables – particularly around the Miracle Mile corridor and Alhambra Plaza – sometimes require an architectural review submittal before permits are approved. This adds cost and time.
- Masonry substrates. Most Coral Gables homes are CBS (concrete block and stucco) construction. Setting an arched unit into masonry takes longer than a wood-frame rough opening and requires different fasteners and sealant chemistry.
- Tight radius profiles. A half-round with a rise-to-width ratio under 0.25 is harder to fabricate and harder to seal correctly. Some of the older bungalow-style homes near Douglas Road have very flat arches that require extra lead time from the fabricator.
- Laminated vs. tempered glass specs. Impact-rated arched units use laminated glass rather than tempered. For large-format curved units, the laminate thickness affects both price and weight – and heavier glass means more labor to set safely.

Why Coral Gables Homeowners Call Winslow for Arched Windows
Coral Gables has stricter architectural guidelines than any surrounding municipality. The city’s original 1920s master plan by George Merrick established design standards that still carry legal weight today – including rules around Oversized Openings – replacement windows can be denied if they don’t match the approved character of the structure. We know that review process. We’ve submitted dozens of permit packages to the Coral Gables Building Department and we know what the plan reviewers look for before they sign off.
The other thing that separates us here is product access. Not every installer is authorized to order from CGI or ES Windows for custom fabrications. Both brands require certification at the installer level, and both offer factory-produced arched units that carry Miami-Dade NOA numbers – which means your permit closes and your insurance carrier has documentation. We’re authorized for both, and we’ve built enough of a track record with their fabrication teams to get accurate lead-time estimates rather than guesses.
Ed Winslow started this company in 2011 doing exactly the kind of jobs other contractors passed on. Arched windows in a historic district with a tight radius and a masonry substrate – that’s not a call most shops want. It’s the kind of call we want. Ed’s name is on the door and on every job we do.
When you call (904) 478-8983, a live person answers. Not a voicemail. Not a call center in another state. Someone who can schedule your measure, pull up permit history for your address, and tell you which fabrication lead times are running long right now. That matters when you’re trying to close a renovation before hurricane season starts in June.

FAQs – Arched & Curved Windows in Coral Gables
Are arched windows required to be impact-rated in Coral Gables?
Yes – any Custom Impact Windows or curved window in Coral Gables must meet Miami-Dade wind-load and impact standards, the same as any other window in the county. There’s no exception for decorative transoms, high-sill windows, or units above the first floor. The NOA (Notice of Acceptance) must be listed on your permit application, and the city inspector will check the label on the installed unit. If you have an older arched window that predates the 2002 code update, it’s almost certainly non-compliant and worth replacing before your next insurance renewal. Call (904) 478-8983 for a free assessment.
How much does arched window replacement cost in Coral Gables?
A single impact-rated half-round transom in Coral Gables typically runs $480 to $1,400 installed, depending on width and substrate. Larger elliptical units or multi-piece curved assemblies for foyers or stairwells can run $2,800 to $6,500 or more. The main cost drivers are custom fabrication (every arched unit is made to order), the masonry installation common in CBS homes, and any historic review fees that apply to your address. We give you an upfront price before any work starts – no estimates that balloon after the old window comes out. Call (904) 478-8983 for a specific number based on your opening.
How long does it take to get a custom arched window fabricated?
Most custom arched and curved units take 7 to 21 days from order to delivery, depending on the fabricator’s current queue and the complexity of the profile. CGI and ES Windows both produce impact-rated arched units with reliable lead times, and we’ll give you a specific estimate when we place the order – not a vague “a few weeks.” Permit processing with the City of Coral Gables typically adds 5 to 10 business days. We start the permit application before the window ships, so both processes run in parallel and your installation date doesn’t slip.
Can you replace just the glass in an existing arched window, or does the whole frame need to come out?
It depends on the frame condition and whether the unit needs to be upgraded to impact-rated. If the existing aluminum frame is structurally sound, plumb, and already carries an NOA number, a glass-only replacement is sometimes possible and costs significantly less than a full unit swap. In practice, most arched frames we see in Coral Gables that are old enough to have failed glass are also showing signs of frame corrosion, warping, or original sealant failure – and replacing glass into a compromised frame just pushes the problem forward. We’ll assess the frame honestly during the measure visit and tell you which approach makes more sense for your specific window. Call (904) 478-8983 to schedule that visit at no charge.
