AfterGeometric & Shaped Windows in South Miami, FL
Custom & Geometric Windows – circles, ovals, arches, trapezoids, octagons, and custom polygon forms – are specialty installations that most general contractors simply aren’t set up to handle. At Winslow Windows & Doors, we measure, order, and install these windows to exact field dimensions, so the finished product fits flush, seals tight, and holds up to South Miami’s heat and hurricane exposure. If you have a shaped window that’s leaking, fogged, or needs upgrading to impact glass, call us at (850) 930-1813 – a real person answers every time, around the clock.
For the full picture of what we do in this category, visit our Custom & Geometric Windows in South Miami page. This page focuses specifically on geometric and shaped window units – the non-rectangular forms that demand custom fabrication and a measurably different installation skill set.
Ed Winslow built this business in 2011 on the principle that every job gets done right or we come back and make it right. That promise applies equally to a round porthole window in a Coral Gables-style home in South Miami and a six-panel trapezoid clerestory in a newer construction in Pinecrest. Shaped windows aren’t a sideline for us – they’re a regular part of what we do.
When You Need Geometric & Shaped Windows
South Miami homes carry a distinct architectural identity. Many were built or renovated in the 1980s and 1990s with round, arched & curved windows, or angled accent windows that were never designed to the impact standards now required under the Florida Building Code. Others have original wood-framed shaped windows that have simply reached the end of their useful life in this climate. Here are the situations we see most often:
- Failed or fogging insulated glass in a shaped unit. When the seal breaks in a double-pane geometric window, the argon escapes and condensation forms between the panes. In South Miami’s humidity, this happens faster in shaped windows because many older units use inferior spacer systems not rated for tropical exposure. The fix is a full-unit replacement – you can’t re-seal an IGU in the field.
- Non-impact shaped windows in a storm-required zone. If your home has a round or arched window that isn’t impact-rated, it’s a code and insurance liability. South Miami falls inside Miami-Dade County’s High-Velocity Hurricane Zone (HVHZ), which has some of the most stringent impact product requirements in the country. Every shaped window we install carries the necessary Miami-Dade NOA (Notice of Acceptance).
- Water intrusion around the frame perimeter. Curved and angled window frames are harder to flash correctly than rectangular ones. In South Miami’s summer rain season – where afternoon storms can dump three inches in an hour – even a minor flashing gap around a half-round becomes a serious leak. We see this regularly in the neighborhoods west of US-1.
- A new custom home or addition requiring shaped windows. If you’re building or adding on in South Miami and your architect has specified circular, elliptical, or geometric accent windows, we handle the measure-to-order process and coordinate with your GC or directly with the permit office.
- Outdated single-pane fixed geometric windows. Many homes in South Miami built before 1995 have single-pane fixed arches or quarter-circles that contribute to high cooling loads. Replacing them with low-E laminated units – available through brands like ES Windows and ECO Window Systems – can measurably reduce the heat gain through those south- and west-facing openings.
- Broken or cracked glass in a shaped frame. Impact glass in a geometric unit is a laminated assembly – a crack doesn’t shatter the way single-pane does, but the unit needs replacing before the integrity of the laminate degrades further. We can often match the existing frame profile so you don’t need to disturb the surrounding wall finish.
Our Geometric & Shaped Windows Process
Installing a shaped window correctly is a different exercise than swapping a standard rectangular unit. The margin for error is smaller, the fabrication lead times are longer, and the flashing details are more involved. Here’s how we handle it, start to finish:
- On-site field measure. We don’t rely on nominal or blueprint dimensions for shaped windows. Ed’s team comes to your South Miami home with calibrated measurement tools and takes multiple reference points across the rough opening – because a circle that’s slightly out of round or an arch whose radius shifts by a quarter-inch at the jamb will produce a unit that doesn’t fit. We document the exact profile before anything is ordered.
- Product selection and NOA verification. Based on your opening dimensions, your impact requirements, and your energy goals, we recommend units from our authorized brands. For geometric shapes, we regularly work with CWS and ECO Window Systems, both of which have Miami-Dade approved product lines for non-rectangular configurations. We verify the NOA for every unit before placing the order – no exceptions, because HVHZ inspections don’t pass on a close-enough product.
- Permit pulling and scheduling. Shaped window replacements in South Miami require a permit through Miami-Dade County when the work involves a structural opening or an impact upgrade. We handle the permit application, submit the NOA documentation, and coordinate the inspection schedule. You don’t have to navigate the county permit portal on your own.
- Existing window removal. Our background-checked, uniformed technicians remove the existing unit carefully to avoid damaging the surrounding stucco or interior finish. On arched and circular openings, the buck framing often needs assessment – we check it before the new unit goes in, not after.
- Installation and weatherproofing. The new geometric unit is set, shimmed, and anchored to the specs required by the manufacturer’s installation instructions and the NOA. Flashing tape, sealant, and any required backer rod are applied in the correct sequence. For curved openings, this step takes longer than a rectangular replacement – we don’t rush it because the weatherproofing on a shaped window is where most callback problems originate.
- Final inspection and cleanup. We walk the installation with you before we leave. You see the finished product, confirm the glass is clear and the frame sits flush, and we go over the Done Right Promise with you directly: if anything isn’t right, call us and we come back. No runaround, no warranty bureaucracy – Ed’s word is the guarantee.
Geometric & Shaped Windows Pricing in South Miami
Shaped windows cost more than rectangular windows of comparable square footage – and that’s true regardless of who installs them. The reasons are straightforward: custom fabrication runs longer, field measuring takes more time, and the installation labor is more involved. That said, the range across jobs in South Miami is wide, and the factors below are what drive your specific number.
| Window Type | Typical Range (supply + install) |
|---|---|
| Small half-round or quarter-round (up to 24″ radius) | $480 – $750 per unit |
| Full round or oval (24″- 48″ diameter) | $700 – $1,200 per unit |
| Large arched or eyebrow unit (over 48″ span) | $950 – $1,800 per unit |
| Trapezoid or triangle fixed geometric | $550 – $1,100 per unit |
| Octagon or polygon accent window | $600 – $1,050 per unit |
| Complex custom multi-angle configuration | Quoted per project |
What affects the final number:
- Size and profile complexity. A symmetrical circle is simpler to fabricate than an ellipse with a custom aspect ratio. More complex profiles cost more in both glass and frame fabrication.
- Glass type. Standard clear laminated impact glass is the baseline. Low-E coatings, tinted glass, or decorative art-glass laminates add to the unit cost. In South Miami’s sun exposure, low-E is almost always worth the upgrade on west- and south-facing shapes.
- Frame material. Aluminum frames (standard for HVHZ impact products) are the most common. Some clients in South Miami specify vinyl-clad or specialty finishes for exterior aesthetics – those add cost but are available through our product lines.
- Buck and structural condition. If the existing rough opening needs framing repairs before the new unit can be set, that adds labor. We identify this during the measure visit, not mid-job.
- Permit and inspection fees. Miami-Dade permit fees are set by the county and vary by job valuation. We include an estimate of these fees in your upfront quote so there are no surprises on the invoice.

FAQs – Geometric & Shaped Windows
Can geometric windows be impact-rated in South Miami?
Yes – custom impact windows in geometric and shaped configurations are available and required under Miami-Dade County’s HVHZ rules if you’re replacing an existing unit or installing new. The key is that the specific shape and size must have a Miami-Dade Notice of Acceptance (NOA) on file for the product being installed. We verify this before ordering any unit. Not every manufacturer produces NOA-approved shaped windows, which is one reason we work with brands like CWS and ECO Window Systems that have documented HVHZ product approvals for non-rectangular configurations. Call (850) 930-1813 and we can confirm availability for your specific window profile.
How much do geometric windows cost in South Miami?
Most geometric window replacements in South Miami run between $480 and $1,800 per unit, depending on size, shape complexity, glass type, and whether any structural work is needed at the rough opening. Simple half-rounds at the lower end; large custom arches or multi-angle configurations at the higher end. These ranges reflect supply and installation combined – we don’t quote one without the other. Call (850) 930-1813 for a free, itemized estimate on your specific windows – it’s the only way to get an accurate number.
How long does it take to get a custom shaped window fabricated and installed?
Fabrication lead time for geometric windows typically runs 3 to 6 weeks from the time an order is placed, depending on the manufacturer’s current schedule and the complexity of your unit. That’s longer than standard rectangular windows, which often ship faster from distributor stock. Once the product arrives, installation in South Miami is usually scheduled within 1 to 2 weeks. Permit processing through Miami-Dade can add time, and we factor that into your project timeline at the outset so you’re not caught off guard mid-process.
Can I replace just the glass in a shaped window, or does the whole unit need to come out?
In most cases, the entire unit needs to be replaced. Shaped window glass is typically a factory-sealed insulated glass unit (IGU) bonded or set into a custom frame – it isn’t designed for field reglazing the way some older rectangular windows were. If the frame itself is structurally sound and the glass is the only problem, there are situations where a glass-only swap is possible, but those are the exception rather than the rule for impact-rated units. We’ll assess your specific window during the measure visit and give you an honest answer about whether a full replacement is necessary or whether a less invasive option exists.
