Fast, Reliable Custom & Geometric Windows Across Miami
Custom and geometric windows in Miami carry a requirement no other major U.S. city enforces the same way: every unit must hold a Miami-Dade Notice of Acceptance (NOA) because the entire city sits inside the High Velocity Hurricane Zone. That changes everything about how these windows are engineered, ordered, and priced. Our team handles the full scope, from arched and curved openings to oversized impact glazing, and we do it with the millwork and code detail Miami’s concrete block homes actually demand. Call (850) 930-1813 and you’ll reach a live person who knows this market.
Ed Winslow put his name on this company in 2011, and he’s the one who stands behind every install. When an architect in Coral Gables specifies a radius window that has to pass HVHZ large-missile testing, or a homeowner in Westchester asks us to replace a 1960s jalousie bay with a curved impact unit, the answer isn’t a shrug, it’s a plan. We’re at home in Miami, and we understand that design intent has to survive both a building inspector and a Category 5 wind load.
Why Winslow Windows & Doors Is Miami’s Preferred Custom & Geometric Windows Company
We’ve built a local reputation in Miami by being blunt about what custom work actually requires here. That means telling a homeowner the truth when an out-of-state quote for a geometric window won’t pass a Miami-Dade building review. It means pricing a job correctly the first time, with the NOA compliance and custom buck framing already in the line items, not discovered halfway through the install. Homeowners in Miami Shores and Hialeah have invited us back for second and third projects, and we don’t take that lightly.
Every technician on a Miami job is background-checked and arrives in uniform, so you know exactly who’s at your door before you open it. Calls are answered by a real person 24/7, not a voicemail loop. And the Done Right Promise applies to every custom geometric window we install, no exceptions. If it’s not done right, we make it right. That’s a hundred-year standard, and it belongs to Ed personally.
We also carry a full menu of standing offers that have no expiration date: $40 off any repair over $200, free second opinions on written estimates, no trip charge inside our home county, and a permanent 10% discount for seniors and veterans. Upfront pricing, written before we order anything. No surprises on the invoice.
Our Custom & Geometric Windows Services in Miami
Most custom window companies can draw a pretty shape. Fewer can get that shape through a Miami-Dade product approval review and keep it watertight against salt-laden Atlantic air for two decades. That’s the work we do. Here’s how it breaks down for Miami homes.
Custom Impact Windows
In Miami, custom impact windows are not an aesthetic upgrade, they’re an insurance requirement. Nearly every geometric opening in the city has to meet HVHZ large-missile standards, which means laminated glass, specific interlayers, and design pressures matched to the exact opening size and floor height. We order from manufacturers that maintain Florida Product Approval for their custom lines, so the unit that fits your trapezoid opening also satisfies your carrier’s opening-protection requirement. A custom impact window in Miami generally runs $900 to $1,800 per opening, depending on size and DP rating, with large or unusual shapes pushing higher.

Geometric & Shaped Windows
Trapezoids, pentagons, parallelograms, octagons, rake-head units, triangles over doorways. Miami’s mid-century CBS homes and its newer architect-designed builds both lean on these shapes. The catch in this city is that a geometric window cut for an inland Florida house often lacks the NOA paperwork Miami-Dade requires. We handle the engineering and the approvals so the shape you want is the shape that gets permitted, not the shape that gets rejected.

Arched & Curved Windows
Radius and arch-top windows are common in Coral Gables Mediterranean revival homes and along Miami’s waterfront streets, where curved glass reads as deliberate design. But a curved impact window in Miami has to hold its large-missile rating across the full arc, and that’s a different product than a flat rectangle with a decorative arch applied to the frame. We work with CWS and ES Windows on true curved and radius impact lines that carry the documentation Miami-Dade inspectors actually ask to see. Arched and curved openings in Miami typically land between $2,500 and $5,000 per unit when impact-rated.

Oversized Openings
A 12-foot glass wall in a waterfront Miami living room is a beautiful thing until a storm throws a 2×4 at it. Oversized custom openings in the HVHZ demand the largest lites, the heaviest laminated glass packages, and framing reinforced far beyond standard residential specs. We’ve installed fixed and operable oversized units in post-Andrew concrete towers and in single-family rebuilds where the new design called for spans the original structure never anticipated. These projects are quoted individually, because the glass package, the lift hardware, and the site access all move the number.

Trusted Brands We Service in Miami
We’re an authorized installer for eight premium brands, and for Miami custom work we lean hardest on CWS, ES Windows, and Mr-Glass because their custom and geometric impact lines carry the Miami-Dade NOA paperwork this city demands. ECO Window Systems also shows up when a project calls for a specific European profile that architects like. We order direct from the manufacturer and manage the approval documents ourselves, so you’re not chasing a permit office or an insurance carrier with a stack of papers you didn’t know you needed. Local Miami jobs run smoother when the installer already owns the compliance path.
Common Custom & Geometric Windows Problems We See in Miami Homes
- Out-of-state orders rejected by Miami-Dade. Every year we get calls from Miami homeowners who ordered an arched or geometric window online or through a national chain, only to have the building department and their insurance carrier both refuse it because it lacks a Miami-Dade NOA. The full reorder costs them months and thousands.
- Geometric impact glass undersized for HVHZ pressure. An estimator who treats Miami like Orlando will spec a design pressure that can’t survive a sustained Category 4 wind load on a first-floor opening near Biscayne Bay. By the time anyone catches it, trim and framing are often already on site.
- Jalousie rough-opening mismatches. Older Hialeah and Westchester CBS homes were framed for the now-extinct jalousie rough-opening standard. Replacing those with a custom geometric impact unit almost always requires custom buck framing to bridge the gap, and most out-of-town quotes never account for the labor.
- Salt-corrosion failures from wrong frame specs. Miami’s salt-laden air off the Atlantic eats standard aluminum frames and degrades glazing seals faster than inland markets. A custom window with a non-marine-grade frame can fail within a decade, even if the glass itself is impact-rated.
Pricing for Custom & Geometric Windows in Miami, FL
Here’s the honest range for Miami. Standard impact windows run $800 to $1,500 per window installed. Impact single-hung units land between $900 and $1,800. Large or custom openings, the kind these projects usually involve, run $2,500 to $5,000 or more. Whole-home packages start around $8,000 and can exceed $25,000 depending on opening count, floor height, and wind-zone requirements. What moves the price in Miami specifically: the number of openings, whether we’re working on a ground-floor exposure where surge and large-missile ratings are highest, the frame material, and whether existing rough openings are jalousie-sized and need custom bucking. Your Custom & Geometric Windows estimate is written, line-itemed, and fixed before we order anything. Call (850) 930-1813 for a free in-home measure and written quote.
What Custom & Geometric Windows Costs in Miami
The pricing anchors above are real Miami numbers, not national averages. A single custom impact window in this market is $900 to $1,800. Arched and curved units are $2,500 to $5,000. A whole-home package of custom geometric openings on a Miami CBS home can run from $8,000 to $25,000 or more. What pushes a Miami quote higher than a Tampa or Orlando quote on the same footprint: HVHZ large-missile requirements, design pressure calculations for ground-floor openings near the coast, custom buck framing on older CBS walls, and the fact that every unit needs Florida Product Approval paperwork filed with the permit. We fix the price in writing before we order your glass, and the lead time on custom fabrication, typically four to six weeks, does not change your number. You get a free in-home measure, a written line-item quote, and a fixed price that survives the whole job. Call (850) 930-1813 to schedule.
Florida Pays You Back
Miami homeowners can stack several programs on custom impact window work. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and a custom impact window installation is exactly the kind of retrofit that qualifies. Florida also exempts impact-resistant windows and doors from sales tax. At the federal level, the 25C energy credit returns 30% of product cost, up to $600 per year, on qualifying units. And many Miami carriers credit around 25% on the windstorm portion of your premium after a wind-mitigation inspection, which runs about $75 to $150. The programs and the carriers set the final numbers, so we never promise a payout. We do make sure the paperwork from your install supports every credit you’re entitled to claim. A comparison worth knowing: impact windows versus hurricane shutters. Shutters are cheaper upfront but require you to hang panels before every storm, on every opening, forever. Permanent impact glass is already in the frame when the warning goes up. In Miami, where storms arrive fast and evacuation windows are short, that difference matters.

FAQs - Custom & Geometric Windows in Miami
Almost never. Miami’s pre-1980s CBS housing stock was overwhelmingly framed for jalousie windows, which used a rough-opening standard that no longer exists in modern manufacturing. When we set a custom trapezoid or radius unit into an older Hialeah or Westchester home, we’re typically building custom buck framing against the concrete block to bridge the gap between the old rough opening and the new unit’s frame. The glass itself can be fabricated to nearly any shape, but the structural interface to a CBS wall is work that has to be done correctly the first time. Call (850) 930-1813 and we’ll measure what you actually have before we quote what you’ll actually need.
Yes. Flood zones and wind zones are separate things in Miami. The entire city sits inside the High Velocity Hurricane Zone, regardless of flood-map designation, and HVHZ requires impact-rated opening protection on every exterior window and door. A custom trapezoid or radius window on a flood-zone-X home still has to carry a Miami-Dade NOA and meet the same large-missile and design-pressure standards as one on the water. The insurance carrier will check.
Properly documented, custom oversized impact windows can strengthen your wind-mitigation inspection report, which is what Miami carriers use to apply windstorm-premium discounts, commonly around 25% on the windstorm portion. The key is that the NOA paperwork, the Florida Product Approval numbers, and the installation details all match what the inspector finds on site. We file that documentation consistently, including design pressures specific to each opening, so your inspection isn’t held up by missing paperwork.
Because every custom geometric unit in Miami has to be engineered to the exact design pressure and large-missile rating for its specific opening, then fabricated with laminated glass interlayers and frame extrusions that carry a Miami-Dade NOA. That’s not an off-the-shelf product. Custom fabrication typically runs four to six weeks, and high-end architects and designers know this going in. What catches people off guard is ordering from an out-of-state supplier without NOA documentation, then losing the entire lead time to a reorder. We fix the price in writing before the clock starts, so the wait is at least predictable. Call (850) 930-1813 for a written quote with the lead time spelled out.
No. A true radius or arch-top window has a curved glass package and a curved frame engineered to carry the impact rating across the full arc, which is a different product than a rectangle with a decorative arch applied to the trim. In Miami, the building department checks the NOA documentation against the actual unit, and a mismatched frame or glass package gets flagged. We order true curved units from manufacturers like CWS and ES Windows that keep current Miami-Dade approvals on their radius and arch lines.
