AfterFast, Reliable Custom & Geometric Windows Across Miami
Custom and geometric windows in Miami run from about $2,500 to $5,000 per opening installed, with whole-home packages typically landing between $8,000 and $25,000 depending on size, shape, and wind-load requirements. Every window we install in Miami carries a Miami-Dade Notice of Acceptance (NOA), because without one, the inspector fails the job and your insurer won’t issue windstorm credits. That’s the non-negotiable baseline here, and we’ve built our entire Miami operation around it since we started taking jobs in the city. Call (904) 478-8983 for a free in-home measure and a written quote that accounts for your specific opening, your block-wall depth, and your wind zone.
We’re Winslow Windows & Doors. Ed Winslow’s name is on the business, and the crew that shows up at your door in Miami is the same crew Ed trained. We don’t sub out to strangers. We don’t sell windows that can’t pass Miami-Dade inspection. And we answer the phone when you call, any hour, with a live person, not a menu tree.
Why Winslow Windows & Doors Is Miami’s Preferred Custom & Geometric Windows Company
Miami homeowners call us because we understand the rules here better than most installers. A custom arch window in Coral Gables has to meet a different approval standard than the same window in Fort Lauderdale, and we don’t assume one spec fits all. We’ve worked in Brickell high-rises where the design pressure on a 30th-floor unit matters more than any aesthetic choice. We’ve worked in Little Havana where a 1958 CBS wall refused a standard jamb depth and we had to custom-fabricate the frame. That kind of local knowledge only comes from doing the work, not from a sales script.
Miami customers consistently tell us three things: the quote matched the invoice, the crew showed up when they said they would, and the inspector signed off the first time. We carry a full suite of marine-grade fasteners and stainless hardware in our South Florida shop specifically for Miami’s salt air, because standard aluminum corrodes within a year in Brickell, Edgewater, and anything within a mile of Biscayne Bay. We coordinate scheduling from our Miami office, so we’re not dispatching a crew from three counties away when you need a measurement.
Every technician is background-checked and arrives in uniform. You know exactly who’s at your door before the truck pulls up. That matters on a tight Miami lot where you might have neighbors on both sides inches away.
Our Custom & Geometric Windows Services in Miami
We handle four main types of work across Miami: custom impact windows, Shingle, Tile & Metal Roofing - Miami, arched and curved windows, and oversized openings. Each one has its own permitting path, its own approval requirements, and its own installation challenges in Miami’s concrete-block housing stock.
Custom Impact Windows
Impact Windows in Miami aren’t optional if you’re replacing a window in a CBs home in West Miami or a condo in Brickell. Miami-Dade County requires every window to carry an NOA, and impact-rated custom windows must handle large-missile testing, not just small-missile. We configure every unit to the design pressure of the specific opening and floor height. A ground-floor casement in Little Havana has a different DP rating than a 20th-floor picture window in Edgewater. We order each window to spec, never off the shelf.
Geometric & Shaped Windows
Triangles, trapezoids, pentagons, half-rounds with angled legs – these shapes show up constantly in Miami’s 1950s and 1960s homes and in the newer spec-built houses in the Gables. The challenge in Miami is that most of these openings were originally cut into CBS block walls and never framed with standard stud spacing. We measure every opening three ways: rough opening width, rough opening height, and jamb depth. Then we order the shaped window to fit the actual wall, not the other way around. The wrong jamb depth leaves gaps that compromise the HVHZ air and water seal, and Miami inspectors check that closely.
Arched & Curved Windows
Arched windows are signature features on Miami Mediterranean revival homes across Coral Gables and the older sections of Coconut Grove. The radius has to match exactly. Too shallow and the window binds. Too tall and the flashing won’t seat. We template each arch on site before ordering, and we only use manufacturers in our lineup – CGI, CWS, and ES Windows – that can hold the arc tolerance we need for Miami-Dade NOA compliance. Curved glass isn’t the place to experiment with a brand we haven’t tested.
Oversized Openings
Miami’s indoor-outdoor living style means walls of glass facing the pool or the bay. These oversized openings need custom-fabricated frames and sometimes multi-panel assemblies that weigh enough to require a crane or a four-man crew. We’ve installed 12-foot sliders and 20-foot transom runs in Key Biscayne homes where access meant coming through a 36-inch side gate and staging entirely in the driveway. Site access changes the quote. If we can’t get a lift through the gate, we plan the rigging differently. That’s part of the estimate, not a surprise on the invoice.
If you’re in Miami and looking for a true custom window, our Custom & Geometric Windows team handles everything from initial measurement to final inspection.

Trusted Brands We Service in Miami
We install and service custom and geometric windows from CGI, CWS, and Eco Window Systems in Miami. These are the brands we trust for Miami-Dade because their NOA documentation is complete, their engineering holds up in brackish coastal air, and their warranties actually get honored when a seal fails in year seven of subtropical humidity. We stock replacement hardware, sashes, and weatherstripping for these lines in our South Florida shop, which means a Miami homeowner isn’t waiting two weeks on a part when a latch breaks or a seal gives out. Fast turnaround matters here because there is no slow season for corrosion.
Common Custom & Geometric Windows Problems We See in Miami Homes
- No Miami-Dade NOA on the window. A window can have a Florida Product Approval and still be illegal to install in Miami-Dade. We see this constantly – someone bought a window online or from an out-of-county installer and the inspector red-tags it on sight. Now the homeowner has a hole in the wall and a window they can’t use.
- Undersized jamb depth on a non-standard rough opening. Miami’s CBS block homes from the 1950s through the 1970s have wall cavities that don’t match modern frame dimensions. A standard jamb won’t seat properly, the air and water seal fails, and the window leaks during the first summer storm. We measure wall depth before we ever order a frame.
- Standard aluminum fasteners on coastal windows. Salt-laden air off Biscayne Bay corrodes plain aluminum hardware within a year. The sash loosens, the window won’t seal, and the manufacturer voids the warranty because the wrong fastener was used. In Miami, marine-grade stainless is the default, not an upgrade.
- Jalousie windows still in place on pre-1970 homes. Little Havana, Hialeah, and older Wynwood blocks still have jalousie windows, but HVHZ code prohibits them and most carriers won’t insure a home that still has one. Any permitted remodel or re-roof triggers a mandatory replacement. If you still have a jalousie window, call us before you list the house or renew your policy.
Pricing for Custom & Geometric Windows in Miami, FL
A geometric or shaped window in Miami typically runs $2,500 to $5,000 per opening installed, including the custom fabrication, the NOA-compliant impact glass, the marine-grade frame, and the labor. A standard impact single-hung in a rectangular opening runs $900 to $1,800. Whole-home packages with mixed shapes and oversized openings start around $8,000 and can reach $25,000 or more depending on the opening count, the size of the windows, and the wind-load requirements of the specific site. Floor height matters. A 20th-floor condo window in Brickell costs more to build and more to install than a ground-floor window in Kendall because the design pressure is higher. Frame material moves the price, too. Aluminum is less expensive but carries corrosion risk in Miami’s coastal air. Thermally broken aluminum or reinforced vinyl costs more upfront and lasts far longer near the bay. We give you a written line-item quote before any work starts, and the number on that quote is the number you pay. Call (904) 478-8983 to schedule a free in-home measure. We’ll walk the site, check the wall depth, and tell you exactly what your windows will cost.
What Custom & Geometric Windows Costs in Miami
Let’s put real numbers on the table. A custom impact window in a standard rectangular opening runs $800 to $1,500 installed at the lower end, though geometric shapes, arches, and oversized units push past that. An impact single-hung runs $900 to $1,800. A large custom opening – a trapezoid in a gable, an arch over a door, a 10-foot transom run – lands between $2,500 and $5,000. Whole-home packages with several custom shapes hit $8,000 to $25,000 and up. What moves the price in Miami specifically: the number of openings, the wind zone and design pressure required, the floor height, the frame material, and whether the wall is CBS block or wood frame. A window in a 1950s CBS home in West Miami needs a custom jamb depth, which adds fabrication cost. A window in a 30th-floor Brickell condo needs a higher DP rating and a crew experienced with high-rise rigging. We measure everything, explain the line items, and give you a written quote. The free in-home measure is exactly that – free. Call (904) 478-8983.
Florida Pays You Back
Miami homeowners can stack several programs to offset the cost of impact-rated custom windows. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and custom impact windows with a Miami-Dade NOA qualify. The state’s sales-tax exemption on impact-resistant windows and doors removes the sales tax from the bill at purchase. The federal 25C energy credit covers 30% of the product cost on qualifying units, up to $600 per year. After installation, a wind-mitigation inspection – typically $75 to $150 – can unlock windstorm-premium credits that average around 25% of the windstorm portion of your homeowners policy. Programs and carriers set the final numbers, so we won’t promise a specific dollar amount. But the incentives are real, and we’ve watched Miami homeowners recover a significant share of their window investment through them. One point worth making clearly: a custom geometric window with no NOA collects none of these incentives. The approval number is the gateway.

FAQs - Custom & Geometric Windows in Miami
Yes. A Florida Product Approval is not sufficient in Miami-Dade County. Every window and door installed in the county must carry a Miami-Dade Notice of Acceptance, or the inspector will fail the job regardless of any other certification. A geometric window with only a Florida Product Approval is illegal to install in Miami. We order every custom window with the NOA documentation matched to the exact configuration. Call (904) 478-8983 to confirm your opening’s requirements with a free measure.
No, you cannot. Jalousie windows are explicitly prohibited under HVHZ code, and most carriers will not insure a home that still has them. Any permitted remodel, Roof Replacement & Installation - Miami, or window replacement on a property with jalousies triggers a mandatory full window replacement order. The permit review is unavoidable, but we manage it end to end. We pull the permit, order the NOA-compliant windows, and schedule the inspection. The jalousie replacement itself is straightforward once the right windows are specified.
We stage the entire job within your property line, follow local work-hour ordinances, and post the required 24-hour notice to neighbors when a shared wall is involved. In dense areas like Little Havana or older Wynwood blocks, that means scheduling noisy cutting for the permitted morning window and keeping materials in a side alley or driveway, never in a neighbor’s space. We’ll walk your lot with you before the job starts and tell you exactly where the truck, the dumpster, and the staging will go. Call us at (904) 478-8983 for a free on-site assessment.
Yes. Design pressure rises with floor height and exposure. A 20th-floor window on a Brickell high-rise faces far higher wind-load requirements than a ground-floor window in Kendall, and the glass, frame, and anchoring all have to be engineered accordingly. We order each unit to the DP rating of the specific opening and floor, never to a generic Miami standard. The NOA documentation we provide reflects the exact configuration. Call (904) 478-8983 and we’ll pull the wind-load data for your building before we quote.
Miami’s peninsula geography means constant salt-laden air off Biscayne Bay and the Atlantic. Plain aluminum fasteners and standard frame hardware corrode within a year, loosening the sash and voiding the manufacturer’s warranty. Orlando is inland and doesn’t face the same salt exposure, so standard hardware lasts there. In Miami, marine-grade finishes and stainless fasteners are not an upsell – they are the only hardware that survives. We install marine-grade hardware on every coastal window without exception.
Working on a Tight Miami Lot: Staging, Noise, and Neighbors
Most Miami homes don’t have a generous side yard and a quiet street to work from. We’re often working on a 5,000-square-foot lot in Little Havana or West Miami with a shared wall inches from the window we’re replacing. This shapes the entire job. Before we quote anything, we walk the site and answer three questions: where does the truck go, where does the material stage, and what time can we actually start making noise. Miami has specific work-hour ordinances, and we don’t cut corners on them. When a shared party wall is involved, we post the required 24-hour notice and schedule the loudest work for the permitted morning window. We stage materials inside your property line, never in a neighbor’s driveway or alley without written permission. On a recent job in Little Havana, we replaced a jalousie window on a 1958 CBS home with a custom impact-rated casement. The shared party wall sat inches from the opening. We posted the notice, kept our staging entirely within a narrow side alley, and scheduled the noisy cutting for the permitted 8 a.m. start. The finished window carried a Miami-Dade NOA and large-missile rating, and the homeowner’s insurer issued a wind mitigation credit on the spot. That’s how a tight Miami lot should be handled.
Density also affects the quote. If access means carrying a 200-pound custom window through a 30-inch gate and across a narrow side yard, the labor line changes. If we need a crane for an upper-floor unit in a Brickell condo, the rigging goes on the quote. We don’t bury these costs. We name them.
And on the comparison question people ask: impact windows versus hurricane shutters. Shutters are cheaper upfront, but they only protect the house when someone is there to hang them. A permanent impact window protects the opening every hour of every storm, no panels to haul out of a garage, no hardware to rust in the salt air, no forgotten shutter on the leeward side. For a home you live in year-round, the impact window is the smarter long-term call. For a seasonal property, shutters can make sense. We’ll tell you straight which one fits. Our Custom & Geometric Windows team can give you an honest comparison for your specific opening.
