AfterFast, Reliable Custom & Geometric Windows Across Miami Beach
Custom and geometric window replacement in Miami Beach typically costs $2,500 to $5,000 per large or shaped opening, and full impact-rated projects on Art Deco buildings run $8,000 to $25,000 and up. The work almost always requires a Miami-Dade County Notice of Acceptance (NOA), and in the South Beach Historic District, a separate review by the Miami Beach Historic Preservation Board before you can pull a permit. That dual approval process catches plenty of mainland contractors off guard. It doesn’t catch us.
Winslow Windows & Doors has been installing Custom & Geometric Windows across barrier-island Florida since 2011, and we know what Miami Beach buildings actually demand: NOA-rated glass, marine-grade aluminum, and profiles that satisfy both the code official and the preservation board. Ed Winslow’s name is on the door and on every job we do. If you’re weighing a custom impact window, an arched unit, or a full geometric replacement, call (844) 901-4551 and a live person answers, day or night.
Why Winslow Windows & Doors Is Miami Beach’s Preferred Custom & Geometric Windows Company
We’re locally owned, not a franchise. That matters in Miami Beach because the city has two approval tracks for windows: the Miami-Dade NOA that governs impact performance, and the Historic Preservation Board review that governs appearance in the Art Deco District. Contractors from western Miami-Dade County routinely miss the second one. We don’t, because our crews work here every week, from South of Fifth to North Beach.
Every technician who shows up to your Miami Beach property is background-checked and in uniform, so you know who’s walking through the gate before the truck stops. When a condo board or HOA on Collins Avenue or West Avenue asks for a window submittal package with NOA numbers, design pressure ratings, and finish samples, we have it ready. No ticket numbers, no call centers. You call, Ed’s team answers.
Our Done Right Promise is simple: if it’s not done right, we make it right. A hundred-year standard. No mainland chain writes that into a quote for a Miami Beach high-rise. We do.
Our Custom & Geometric Windows Services in Miami Beach
Custom Impact Windows
Custom impact windows in Miami Beach start around $1,200 per opening for standard sizes and climb to $4,500-plus for non-standard shapes in HVHZ wind zones. Every unit we install carries a Miami-Dade NOA and is matched to the design pressure the building actually requires, not a generic Florida Product Approval from some inland test lab. In Mid-Beach condos off Indian Creek Drive, that’s routinely the difference between passing inspection and a tear-out order.
Geometric & Shaped Windows
Circles, triangles, trapezoids, pentagons. Miami Beach’s Art Deco and Mediterranean Revival buildings are full of them, because the original architects treated windows as ornament, not punch-outs. We fabricate geometric units with true divided lites where the Historic Preservation Board requires them, and we spec marine-grade aluminum so the mitered corners don’t rot out in salt air. A 1930s hexagon window on a Euclid Avenue mid-rise is a different animal than a new-construction square in Doral, and we quote it that way.
Arched & Curved Windows
Arched windows dominate the upper floors of South Beach’s Art Deco stock, and they’re the hardest units to get through both Miami-Dade and the preservation board. The arch radius must match the original, the muntin pattern must replicate the steel sash profile, and the glass still has to meet NOA impact standards. On one 1930s low-rise off Ocean Drive, our crew replaced original single-pane steel casements with custom arched impact-rated units from ES Windows. The HPB required true divided-lite muntins and a specific bronze finish, so we spec’d a Miami-Dade NOA-rated insulated glass unit with a laminated interlayer and matched the steel profile, then handled the HPB submittal before we ever pulled the building permit. That’s the order of operations in Miami Beach, and it’s non-negotiable.
Oversized Openings
Full-height corner windows, sliding glass walls, and formal entry transoms in North Beach MiMo condos and newer luxury towers on West Avenue all fall into oversized territory. These openings run $2,500 to $5,000 per unit installed, and the engineering matters more than the glass. A 12-foot-wide custom mitered frame in a 20-story building on the beachside of Collins Avenue has to hold a design pressure rating that inland Florida never sees. We compute it per opening, per elevation, per floor height, and we don’t guess.

Trusted Brands We Service in Miami Beach
We’re an authorized installer for PGT, CGI, and ViewLux, along with ES Windows for historic-profile work. For Miami Beach customers, that means we can pull the exact NOA documentation a condo board or the HPB will ask for, straight from the manufacturer’s Miami-Dade approvals file. We don’t stock generic parts and hope. When a board wants to see the PGT NOA for a specific impact casement, we hand it over before the first submittal meeting. Fast turnaround, correct paperwork, done.
Common Custom & Geometric Windows Problems We See in Miami Beach Homes
- Sill corrosion on ground-floor frames. Sunny-day tidal flooding on West Avenue and around Sunset Harbour submerges door thresholds and window sills in brackish water. Standard aluminum corrodes at the seam within a few years; marine-grade alloy with proper sill flashing is the only fix that lasts. We see this failure constantly in Miami Beach and almost never 15 minutes west.
- Non-NOA units ordered by out-of-town contractors. A homeowner hires a mainland crew, the crew orders a custom arch with a Florida Product Approval but no Miami-Dade NOA, and the inspector red-tags the job on day one. The owner pays for the tear-out. We quote NOA-rated glass from the first line item so that never happens.
- HPB rejection on historic-profile replacements. The Miami Beach Historic Preservation Board reviews muntin pattern, profile depth, and finish color separately from the permit. Contractors who skip that step get ordered to remove compliant but unapproved windows at their own cost. We’ve never had an HPB rejection, because we never skip the submittal.
- Stress cracks on oversized geometric units. A heavy impact-rated laminate in a large trapezoid or arch needs a frame engineered for the glass weight plus the wind load. Cheap fabricators under-spec the frame, and the glass cracks at the corner within a year. We engineer the opening, not just the product.
Pricing for Custom & Geometric Windows in Miami Beach, FL
Here’s where honest numbers help. A standard impact window replacement in Miami Beach runs $800 to $1,500 per opening installed. Impact single-hung units run $900 to $1,800. Large or custom-shaped openings, the geometric work this page is about, run $2,500 to $5,000 per unit. Whole-home packages on Art Deco buildings start around $8,000 and go past $25,000 depending on opening count and HPB requirements. What moves the number: wind zone and floor height (high-rise openings above 30 feet cost more because design pressure requirements rise), frame material (marine-grade aluminum vs standard), true divided lites (required in the historic district), and the dual approval paperwork. We give free in-home measurements and a written line-item quote before any deposit changes hands. Call (844) 901-4551 for your free estimate.
What Custom & Geometric Windows Costs in Miami Beach
For planning purposes, here’s what Miami Beach homeowners actually pay. Impact windows generally run $800 to $1,500 per window installed. Single-hung impact units run $900 to $1,800. Large or custom openings, which covers most geometric and arched work on older Miami Beach buildings, run $2,500 to $5,000. Whole-home packages range from $8,000 to $25,000 and up, and in the Art Deco District the high end reflects HPB submittal work, true divided lites, and historic finishes. Floor height matters too: a custom arch on the fourth floor of a Collins Avenue condo has a higher design pressure requirement than the same arch at grade. We measure, we engineer, we quote it in writing. The quote is free, and it’s an actual number, not a range with an asterisk.
One comparison worth making: impact windows versus hurricane shutters. Shutters keep you legal in a storm, but someone has to haul panels out, mount them, and hope they remembered the hardware. Custom impact windows do the job permanently, with no panels, no warning scramble, and no shutters to store in an already-tight South Beach condo. For geometric openings especially, shutters often don’t fit the shape at all. Windows do.
Florida Pays You Back
The incentives stack in your favor, though nobody can promise the final dollar figure. My Safe Florida Home matching grants can cover up to $10,000 in qualifying wind-mitigation upgrades for eligible homeowners. Florida law exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit covers 30% of product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection ($75 to $150), most Miami Beach homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of their policy. The carrier sets the final number, and program funds run out. What we provide is the documentation, the NOA numbers, and the installed product that lets you apply.

FAQs — Custom & Geometric Windows in Miami Beach
A Miami-Dade NOA is required. A Florida Product Approval alone will not pass inspection in Miami Beach for an impact-rated custom window. The NOA is the stricter standard, tested for the high-velocity hurricane zone conditions that apply on this barrier island. If a quote includes only an FL approval number, push back before you sign. Call (844) 901-4551 and we’ll confirm the NOA status of any unit we quote.
It needs Miami Beach Historic Preservation Board approval, reviewed separately from the building permit. The HPB checks profile depth, muntin pattern, and finish color against the building’s original design. Contractors who skip this step get ordered to remove the windows at their own cost. We run the HPB submittal before we pull the permit, every single time.
Use marine-grade aluminum and a properly flashed, elevated sill pan. Miami Beach’s chronic sunny-day tidal flooding repeatedly submerges ground-floor sills in brackish water, which destroys standard aluminum within 5 to 7 years. The fix is material spec, not paint. On any ground-floor opening in 33139 or the bayfront corners of 33140, we quote marine alloy with sealed sill flashing by default.
Yes, provided the window carries a Miami-Dade NOA and the installation is documented with photos and product-approval numbers. The wind-mitigation inspector verifies the NOA, confirms the opening protection is present, and the carrier applies its credit, which averages around 25% on the windstorm portion in Miami Beach. No guarantees on the exact savings, but the documentation we provide is what makes the credit possible. Call (844) 901-4551 for an exact quote on your openings.
It depends on the floor height, the building elevation, and the wind zone, but a beachfront high-rise opening on Collins Avenue will typically require a design pressure rating well above the baseline for inland Miami. We calculate the required DP per opening and match the unit to the Miami-Dade NOA for that exact configuration. We never install at a rating below what the engineering calls for, and we document the number for your permit and your insurance file.
