Fast, Reliable Custom & Geometric Windows Across Miami
Custom and geometric windows in Miami are not a side project for us. They’re a discipline. A true custom-shaped impact window here has to carry a Miami-Dade Notice of Acceptance (NOA), survive large-missile impact testing, and get anchored correctly into concrete block. That’s what we do. Ed Winslow has been running Winslow Windows & Doors since 2011, and his name sits on every job we finish. If you’re in Miami and you need an arched window, a radius unit, a trapezoid, or a true custom impact window, call (863) 656-0462 for a free in-home measure and written quote. A real person answers, 24 hours a day.
Why Winslow Windows & Doors Is Miami’s Preferred Custom & Geometric Windows Company
We’ve worked enough Miami openings to know what’s behind the drywall before the demo blade ever touches it. Older CBS homes in Little Havana, Hialeah, and Westchester hide spalled concrete, failed lintels, and rusted steel bucks. Big-box installers quote those jobs blind. We don’t. We inspect first, write allowances into the contract, and price every surprise in writing before we touch it.
Miami homeowners also know us for what happens after the install. Our 36500-Day Done Right Promise means if it’s not done right, we make it right. That’s a hundred-year standard, and it’s not marketing copy. It’s Ed’s word. We’re locally owned, owner-operated, with a published address and license number. Every technician is background-checked and uniformed. When the truck pulls up in Coral Gables or North Miami Beach, you know exactly who’s walking to your door.
Our Custom & Geometric Windows team handles everything from single radius units to full geometric window walls. Dispatch and scheduling for Miami are coordinated from our South FL office, and crews serve Miami locally.
Our Custom & Geometric Windows Services in Miami
Custom Impact Windows
A custom impact window in Miami means laminated glass, heavy-duty frames, and a Miami-Dade NOA for the exact configuration. We spec every unit to the opening’s design pressure, never a generic “+/-” that won’t pass. For a 1950s CBS home in Little Havana, that often means setting a new aluminum buck with tapcon anchors and rebuilding stucco returns to match the original profile.

Geometric & Shaped Windows
Trapezoids, triangles, pentagons, parallelograms. Miami has thousands of these openings, and most were framed wrong the first time. We measure, template, and order each unit from fabricators who understand HVHZ requirements. No forcing a wood-frame-sized unit into a block reveal. No undersized fasteners. No voided NOA.

Arched & Curved Windows
Radius and arched windows are common on Miami’s Mediterranean revival and mid-century homes, but they demand precision. The arc has to match the existing opening, or you’re doing stucco work you never budgeted for. We template every curve on-site. On one 1950s CBS home in Little Havana, we removed a three-sided jalousie bank and found the original concrete jamb had spalled behind the lintel. Our crew chipped back the failed block, set a new aluminum buck with tapcon anchors, and installed an arched custom impact window with laminated glass interlayer and a Miami-Dade NOA, then rebuilt the stucco returns to match the original profile. That’s what an inspection-first approach looks like.

Oversized Openings
Large custom openings, geometric window walls, and floor-to-ceiling fixed units need engineering, not guesswork. Miami’s wind zone means every unit gets matched to its design pressure rating. We pull the permit, submit the NOA documentation, and schedule the inspection. You get a window that passes first time.

Common Custom & Geometric Windows Problems We See in Miami Homes
- Shaped windows forced into CBS block reveals. A wood-frame-sized unit gets wedged into an older masonry opening with undersized fasteners or no aluminum buck at all. The first wind event cracks the jamb, and the NOA is voided. We see this constantly in Hialeah and Westchester.
- Missing or voided NOA documentation. Curved or oversized impact glass without a Miami-Dade NOA gets spec’d from a supplier outside the HVHZ. It fails inspection, and the homeowner is left with an uninsurable opening plus a second demolition bill.
- Salt spray corrosion on barrier islands. Miami Beach and Sunny Isles Beach sit right on the Atlantic. Salt-laden air pits uncoated custom aluminum frames at corner welds within two seasons. The first hurricane exposes hairline cracks that were invisible at install.
- Jalousie windows that can’t be insured. Pre-1970 CBS homes throughout Little Havana, Overtown, and Hialeah still have louvered jalousie windows. They provide virtually no wind-borne debris resistance and fail every HVHZ requirement. Most modern homeowner policies effectively won’t insure them.
Pricing for Custom & Geometric Windows in Miami, FL
Here’s what Miami actually costs. A standard impact window runs $800 to $1,500 per unit installed. An impact single-hung is $900 to $1,800. Large or custom openings, geometric and arched units included, typically run $2,500 to $5,000 per opening. Whole-home packages in Miami start around $8,000 and climb past $25,000 depending on opening count, floor height, and wind zone.
What moves the price in Miami: masonry anchoring into CBS block, stucco repair around every opening, and NOA documentation per configuration. Wood-frame markets don’t carry those costs. We do a free in-home measure, give you a written line-item quote, and never change the price once work starts unless you approve it. Call (863) 656-0462 to schedule yours.
What Custom & Geometric Windows Costs in Miami
For a true custom geometric window in Miami, plan on $2,500 to $5,000 per opening installed. That’s the realistic range for arched, radius, trapezoid, or oversized impact units. If the opening is a standard rectangle and you just need impact glass, you’re back in the $800 to $1,500-per-window range.
In Miami specifically, you’re paying for more than the glass. CBS block anchoring with tapcon fasteners, a new aluminum buck where the old framing failed, stucco repair, and Miami-Dade NOA documentation all add labor hours. Floor height matters too: a second-story arched unit on a Coral Gables Mediterranean costs more to set than a first-floor unit in Westchester. Wind zone drives the glass spec. We give you a written quote that itemizes every one of these, so you’re never guessing. The in-home measure and quote are free.
Florida Pays You Back
Miami homeowners get a real stack of incentives on impact windows, and you should claim what applies. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida also has a sales-tax exemption on impact-resistant windows and doors. The federal 25C energy credit can return up to 30% of product cost on qualifying units, capped at $600 per year. After a wind-mitigation inspection ($75 to $150), most Miami homeowners also see windstorm premium credits averaging around 25% on the windstorm portion of their policy.
No guarantees on final amounts. Programs and insurance carriers set their own numbers. What we can do is install units that qualify: Miami-Dade NOA, large-missile rated, design pressures matched to the opening, never a rating above +/-100 PSF. If you’re comparing impact windows against hurricane shutters, remember that shutters only help when someone is home to hang them, and they don’t stop wind-driven rain or air-pressure failures. Impact windows are permanent protection, no panels to hang, and they work whether you’re in Miami or up in New York when the storm hits.

FAQs - Custom & Geometric Windows in Miami
Yes. A Miami-Dade Notice of Acceptance is separate from Florida Product Approval and stricter. Every product-specific configuration, including custom geometric shapes, must carry an NOA to be legal in Miami-Dade’s High-Velocity Hurricane Zone. A Florida Product Approval alone doesn’t meet Miami code. We file the NOA documentation for every opening we install, and our inspector sees it before the window goes in. Call (863) 656-0462 to check your current units.
Usually, yes. We remove the jalousie assembly, chip back any failed block, set a new aluminum buck with tapcon anchors, and install the arched impact unit with proper stucco returns. No full reframe needed. The catch is what’s behind the jalousie, which is why we inspect before we quote. If there’s hidden spalling or a bad lintel, you’ll know the cost in writing before we start.
They can move the price up, but only after you approve it in writing. Miami’s older CBS homes hide spalled concrete, rusted steel bucks, and failed waterproofing behind original windows. We write allowances into every contract for exactly these surprises. If we open the wall and find a problem, we price it, show you photos, and get your sign-off before we do anything else. No change orders you didn’t authorize. Call (863) 656-0462 for a free estimate.
If it’s coated and built for marine exposure, yes. Miami Beach salt spray pits uncoated aluminum frames at corner welds within two seasons. We spec custom units with marine-grade coatings and inspect corner welds on every install. Years later, the NOA sticker is still on the frame, the anchors are still set in block, and the wind mitigation inspection still passes. That’s the standard. Call (863) 656-0462 to schedule an inspection of your existing units.
Because the NOA is the proof that the unit passed large-missile impact testing for Miami’s wind zone. An invoice just says you paid for a window. The NOA says the window is legal, impact-rated, and tied to a specific product configuration. Without it, insurers treat the opening as unprotected. We provide the NOA documentation for every custom and geometric window we install in Miami, and we file it with the permit package so the inspector sees it first. Call (863) 656-0462 for a free review of your current windows.
Ed’s name is on the door, and on every job we do. If you’re in Miami and your shaped window is leaking, failing, or never had the right NOA, call (863) 656-0462 today. The estimate is free. The answer is always a real person. The one down the road.
