AfterFast, Reliable Custom & Geometric Windows Across Miami Beach
Custom and geometric windows in Miami Beach typically run $2,500 to $5,000 per large or shaped opening installed, and the permitting path here is unlike anywhere else in Florida. You have to satisfy two masters: the Miami-Dade High Velocity Hurricane Zone code and, in much of the city, the Historic Preservation Board. Winslow Windows & Doors has worked both sides of that table since 2011. If you’re planning a geometric replacement on South Beach, Mid-Beach, or North Beach, call (850) 998-3090 and Ed Winslow will walk you through what actually passes.
Why Winslow Windows & Doors Is Miami Beach’s Preferred Custom & Geometric Windows Company
Ed Winslow put his name on this business in 2011, and he still answers the phone. That matters on a job where the framing depth, muntin profile, and sightline width can make or break a permit. We’re not a national chain routing calls to a call center in another state. When you call (850) 998-3090 about a custom arched window on a 1930s low-rise off Washington Avenue, you’re talking to a person who knows what the Miami Beach Preservation Board will and won’t accept.
Our Custom & Geometric Windows team has installed shaped units in Art Deco buildings, 1960s condo towers along Collins Avenue, and newer Mid-Beach townhomes. Every technician arrives in uniform, background-checked, with a name you’ll actually recognize when they step out of the truck. We publish our address and license number. We don’t hide behind a PO box after the job is done.
Homeowners in Miami Beach call us because we show up when we say we will, price the job in writing before we start, and stand behind the work under the Done Right Promise. If it’s not done right, we make it right. That’s not a slogan. That’s Ed’s name on the line.
Our Custom & Geometric Windows Services in Miami Beach
Custom Impact Windows
Every impact window in Miami Beach we install carries a Miami-Dade County Notice of Acceptance. That’s the baseline, not the finish line. We match design pressure ratings to the specific opening, floor height, and exposure on your building. A third-floor unit facing Biscayne Bay takes a different load than a ground-floor storefront on Lincoln Road. We order per configuration, never from a generic chart.
Geometric & Shaped Windows
Circles, triangles, parallelograms, hexagons. Miami Beach’s Art Deco stock loves angles and curves, and we love building them. The catch here is that a geometric window with the right NOA number can still get rejected if the frame depth or sightline doesn’t match the original steel profile. We source from manufacturers and specialty fabricators who understand that a Miami Beach window has to satisfy an HVHZ inspector and a preservation officer on the same day.
Arched & Curved Windows
Arched windows on Miami Beach are common in 1930s and 1940s buildings, and they frequently need replacement after decades of salt exposure. What we find when we pull the old unit is often worse than the window itself: corroded steel lintels, rotted wood bucks, and concrete banding that’s lost its anchorage. We rebuild the opening, not just swap the glass. The arch radius has to be field-measured to the sixteenth of an inch; a factory template from a photo won’t cut it on a 85-year-old building.
Oversized Openings
Large fixed picture windows, floor-to-ceiling corner glass, and sliding wall systems on Miami Beach high-rises require scaffolding permits, crane or hoist logistics, and HOA coordination. We’ve done this on occupied buildings where residents stay in place during the work. Our crews stage materials to minimize lobby disruption and complete the unit swap after the custom fabrication arrives. In some Mid-Beach corridors, city road-raising projects have altered finished grade, which changes sill height requirements. We field-verify before we order.

Trusted Brands We Service in Miami Beach
We’re authorized installers for PGT, CGI, among eight premium brands we can order from without a middleman. That authorization matters in Miami Beach, where a custom geometric window often needs a narrow-sightline frame that mimics original steel casement proportions. PGT and CGI both produce Miami-Dade NOA-certified lines with slim frame options that have passed the Miami Beach Historic Preservation Board on projects we’ve completed. We also service Miami Beach Therma Tru service on the same openings when the project includes entry doors. Parts and hardware stocked locally for Miami Beach customers mean less downtime when a lock, hinge, or weep system fails between replacements.
Common Custom & Geometric Windows Problems We See in Miami Beach Homes
- Salt corrosion killing frames in under a decade. Miami Beach sits between the Atlantic and Biscayne Bay, so every elevation gets salt-laden air, not just oceanfront facades. Aluminum jambs, weep holes, and hardware that would last 25 years in Coral Gables regularly show pitting and failure here within 10. We see it constantly on custom arched units where water pools at the sill and eats through the frame from the inside out.
- Historic Preservation Board rejection stalls. A geometric impact window ordered with the correct design pressure but the wrong sightline depth gets rejected, and the project sits for months while a compliant product is re-sourced. We’ve been called in to rescue jobs where the original contractor ordered off a standard spec sheet without checking the board’s requirements. On Miami Beach, that mistake costs weeks and thousands.
- Concrete banding anchorage failure behind old steel casements. The 1930s and 1940s buildings that give South Beach its character used poured-concrete banding with steel rebar that’s now 80-plus years old. When we remove original steel casements, the concrete often crumbles at the jamb. You can’t just screw a modern frame into powder. We rebuild the anchorage before installing the new unit.
- Road-raising changed the ground, and the opening no longer matches. Miami Beach’s ongoing street elevation program has shifted finished grade on multiple Mid-Beach blocks. A factory-measured oversized geometric window orders arrive and the sill no longer meets HVHZ water-intrusion clearance. We field-verify grades before fabrication, which saves you a very expensive refit.
Pricing for Custom & Geometric Windows in Miami Beach, FL
Here are real numbers for the Miami Beach market. A standard impact window replacement runs $800 to $1,500 per opening installed. Impact single-hung units run $900 to $1,800. Large or custom geometric openings, which require field templating, specialty fabrication, and often historic review, run $2,500 to $5,000 per unit. Whole-home packages on a Miami Beach condo or single-family home run $8,000 to $25,000 or more depending on opening count, floor height, and wind zone exposure.
What moves the price in Miami Beach specifically: whether your building falls in the Art Deco Historic District (historic compatibility review adds engineering and documentation time), whether you’re on a high floor facing open water (higher design pressures, heavier glass, bigger cost), and whether the building is mid-rise or high-rise (scaffolding and crane logistics). We don’t pad the quote. We give you a written, line-item price before work starts, and the price doesn’t change unless you change the scope. Call (850) 998-3090 for a free in-home measure and a written quote.
What Custom & Geometric Windows Costs in Miami Beach
Let’s put the numbers in one place. Impact windows in Miami Beach generally start around $800 per window installed and run to $1,500 for standard sizes. Impact single-hung units land between $900 and $1,800. Large or custom geometric openings, the kind Miami Beach’s older buildings demand, run $2,500 to $5,000 each. Whole-home packages range from $8,000 to $25,000 and up, depending on building height and exposure.
The price is driven by four things: how many openings you’re replacing, what wind zone and floor height your building sits in, what frame material and finish you choose, and whether the Historic Preservation Board has jurisdiction. We don’t quote over the phone. We come out, measure every opening, check the building’s existing NOA documentation if available, and hand you a written quote that breaks the job down opening by opening. That’s free. Call (850) 998-3090.
Florida Pays You Back
Miami Beach homeowners doing custom impact window work have incentives available right now, and we’ll point you to them without overpromising. The My Safe Florida Home program has offered matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida also exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit can apply at 30% of product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection, which typically costs $75 to $150, many Miami Beach homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of their policy. These programs change, and your insurance carrier sets the final numbers, but we’ll help you document the work correctly so you’re positioned to claim what’s available.
One more comparison worth making: impact windows beat hurricane shutters for Miami Beach specifically because there’s no panel to hang before a storm, no storage locker, and no step where you’re not home when the evacuation order comes. Permanent protection that’s already in place. For a condo or a single-family home on a barrier island, that’s not a luxury. It’s the right call.
The Wall You Don’t See Is the Quote You Didn’t Get
Opening up an older Miami Beach home during a Roof Replacement & Installation - Miami Beach or window replacement turns up things nobody planned for. We’ve been doing this since 2011, and we can tell you exactly what we find in 1930s South Beach buildings and 1960s concrete condos along Collins Avenue: outdated wiring run through window headers, undersized or rotted framing, failed waterproofing behind the stucco, and code upgrades that a permit triggers once the wall is open. This is the single biggest reason a remodel quote moves after work starts, and most homeowners never see it coming.
Here’s how we handle it. We inspect first. Before we ever order your custom geometric window, we look at the opening, the surrounding framing, the anchorage points, and what’s behind the stucco where we can access it. Then we write allowances into the contract for the unknowns, clearly identified, with real dollar figures. If we open the wall and find rebar anchorage shot or a header undersized for a Miami Beach wind load, we stop, photograph it, show you exactly what we found, and hand you a written price for the repair before we touch another inch. You approve it or you don’t. Nothing gets added to your invoice without your signature.
On a 1939 South Beach low-rise off Collins Avenue, our crew removed the original steel casements and found the poured-concrete banding had lost most of its original rebar anchorage. We rebuilt each jamb with engineered grout and installed PGT custom impact-rated casements with a narrow-sightline frame that passed both the HVHZ inspector and the Preservation Board. The owner now gets the wind mitigation credit and keeps the original horizontal banding look. That’s how we work. Inspection first, allowances written into the contract, and any surprise priced and approved in writing before we touch it.

FAQs - Custom & Geometric Windows in Miami Beach
No. A Miami-Dade NOA proves the window meets impact code, but the Miami Beach Historic Preservation Board can and does reject NOA-certified windows whose frame depth, sightline width, muntin profile, or color doesn’t convincingly replicate the original thin-profile steel casement look. You need a narrow tier of specialty historic-compatible impact products. We source those and have passed board review under this dual constraint. Call (850) 998-3090 and we’ll tell you honestly whether your planned window will clear both hurdles.
Because Miami Beach sits inside the High Velocity Hurricane Zone, which requires stricter design pressures than Broward or Palm Beach, and because the Historic Preservation Board layer in much of the city adds engineering, documentation, and review time that doesn’t exist in Fort Lauderdale or West Palm Beach. The same PGT or CGI product line often needs a different configuration and a different approval path in Miami Beach. That’s the cost difference in real terms. Call (850) 998-3090 for a written quote on your specific opening.
Miami Beach is a barrier island between the Atlantic and Biscayne Bay, so salt-laden air reaches every building elevation, not just oceanfront units. Aluminum frames, weep holes, and hardware corrode far faster here than inland. We see custom arched windows with decade-old frames pitted and leaking at the sill. We select finishes and hardware rated for coastal exposure and recommend maintenance schedules specific to Miami Beach conditions. Call (850) 998-3090 to discuss what we’re seeing on buildings like yours.
We stop and show you. Before any work starts, our contract includes written allowances for framing unknowns. When we open the wall and find a header undersized for Miami Beach wind loads or rot from decades of salt-driven moisture, we photograph it, explain it, and give you a written price for the repair before we proceed. Nothing is added without your approval. Call (850) 998-3090 and ask us how the allowance structure works on your project.
Yes, in most cases a custom arched impact window with the correct Miami-Dade NOA can qualify for wind-mitigation credits on the windstorm portion of your policy, which Miami Beach homeowners often see averaging around 25% after a wind-mitigation inspection. The inspection typically costs $75 to $150, and your carrier sets the final credit. We’ll install and document the work so the inspection goes smoothly. Call (850) 998-3090 for a free estimate.
