Fast, Reliable Custom & Geometric Windows Across Miami Beach
Custom and geometric windows in Miami Beach, FL typically run $1,200 to $4,800 per opening installed, with arched and radius units landing between $2,500 and $5,000 once you factor Miami-Dade NOA engineering and Historic Preservation Board documentation. Every shaped window we fabricate for this barrier island must clear two separate approvals that most Florida contractors never deal with, which is why we handle the paperwork, the engineers, and the permit review from day one. If you’re replacing a jalousie window, restoring an Art Deco facade, or opening up an oversized view corridor on a waterfront condo, call Winslow Windows & Doors at (727) 291-4678 for a free in-home measure and a written line-item quote. Ed Winslow owns this company, and Ed’s name goes on every job we do in Miami Beach.
Why Winslow Windows & Doors Is Miami Beach’s Preferred Custom & Geometric Windows Company
We’re the company Miami Beach homeowners call when a big-box installer tells them a radius window “can’t be done” or when their permit gets red-flagged by the city. Our crews work in South Beach, mid-Beach, and North Beach every week, so we know which buildings off Collins Avenue, Alton Road, and 63rd Street trigger Historic Preservation Board review before we even measure the rough opening. Every technician who arrives at your door is background-checked and in uniform, and when you call us at 2 a.m. with a blown-out window after a storm, a live person answers. Not a voicemail. Not a call center.
Locally owned by Ed Winslow with a published address and license number, Winslow has been installing impact-rated custom windows since 2011, and our Done Right Promise means if the work isn’t done right, we come back and make it right. That’s a standard of accountability written into every job. We’ve never once asked a Miami Beach customer to call an 800 number and hope for the best.
Our Custom & Geometric Windows Services in Miami Beach
Custom Impact Windows
Every custom impact window we install in Miami Beach carries a Miami-Dade NOA for the exact frame profile, not just the glass package. On a barrier island where the Atlantic and Biscayne Bay both throw salt spray at your building envelope, we spec marine-grade coatings and stainless fasteners as standard, because standard anodized aluminum can show pitting failure in under five years out here. Our Custom & Geometric Windows team matches design pressures to the opening, so a third-floor corner unit on West Avenue gets a different engineered package than a ground-floor storefront on Lincoln Road.

Geometric & Shaped Windows
Triangles, trapezoids, pentagons, parallelogram windows. Miami Beach’s Mid-Century and Art Deco buildings are full of them, and most replacement companies won’t touch them because the engineering has to be done per-opening. We do the structural calcs, get the NOA issued, and fabricate the finished unit so it reads correctly against the original sightlines, especially in the Historic District.

Arched & Curved Windows
Arch-top and radius windows are common on 1920s Mediterranean Revival buildings along Flamingo Park and the Venetian Islands, and they’re the most likely units to get bounced by the Historic Preservation Board if the mullion profile reads too modern. We fabricate arched units that hold the original steel casement proportions while still meeting current HVHZ large-missile impact standards. The two requirements pull against each other, which is exactly why you want a company that has done this before.

Oversized Openings
Floor-to-ceiling fixed geometric glass on a Biscayne Bay-facing penthouse is a different animal than a standard bedroom window. Oversized openings in Miami Beach need heavier frames, stronger mullion packages, and often a crane or lift plan for installation in mid-rise and high-rise buildings. We’ve installed custom fixed units up to 12 feet wide in Miami Beach condos where the HOA, the city, and the structural engineer all had to sign off before glass ever touched the building.

Trusted Brands We Service in Miami Beach
We’re an authorized installer for PGT, CGI, and we stock common replacement parts and hardware for those product lines locally so Miami Beach customers aren’t waiting on a warehouse in another state. When a PGT custom slider in a North Beach rental gets jammed or a CGI casement on a historic South Beach building needs a new operator, we can usually source the part fast because we run these products through Miami Beach installs constantly. We don’t substitute off-brand hardware and we don’t tell you to “upgrade” because we don’t stock what you already own.
Common Custom & Geometric Windows Problems We See in Miami Beach Homes
- Salt-spray corrosion eating the frame and hardware: Being 30 blocks from the ocean here is not the same as being five blocks from the ocean in Coral Gables. We regularly rebuild rough openings on mid-Beach buildings where the original jalousie jambs have corroded to the point of structural failure.
- Catalog windows with no Miami-Dade NOA: A homeowner specs a beautiful arch window online, pays a deposit, and then the city rejects the permit because the engineered mullion package never got a NOA for Miami Beach’s wind zone. We see this at least once a month.
- Jalousie replacements that kick back at plan review: Any louvered opening in North Beach or mid-Beach has to be replaced with an impact-rated system meeting the design pressure of the original wall assembly. Submit a standard double-hung and the city sends it back. We know this going in.
- Historic Preservation Board denials on compliant windows: A window can carry full HVHZ approval and still get rejected on a Collins Avenue Art Deco building because the sightline reads wrong. We reprofile custom units so they pass the board without sacrificing a single performance rating.
Pricing for Custom & Geometric Windows in Miami Beach, FL
A standard custom impact window in Miami Beach runs $1,200 to $2,400 opened-installed for a modest geometric shape. Arched and radius units start around $2,500 and can push $5,000 or more depending on the radius, the frame material, and whether the building is in the Historic District review zone. Here’s what moves the number: size and shape, wind zone and floor height, frame material and finish, whether the opening needs rough-opening rebuild work, and whether Historic Preservation Board submittal is required. Whole-home packages on a 2,000-square-foot Miami Beach house typically fall between $12,000 and $28,000. Every quote we give is a fixed price, line-itemed, with no change orders unless you change the scope. Call (727) 291-4678 for a free in-home measure.
What Custom & Geometric Windows Costs in Miami Beach
Let’s put real numbers on it. Impact windows generally run $800 to $1,500 per window installed. Impact single-hungs fall between $900 and $1,800. Large or custom openings, the kind Miami Beach is full of, run $2,500 to $5,000. Whole-home packages start around $8,000 and can exceed $25,000 on high-rise condos or historic properties with complex sightline requirements. In Miami Beach specifically, the cost drivers are threefold: your wind zone and floor height, whether the opening needs a custom NOA for a shaped frame profile, and whether the Historic Preservation Board has jurisdiction. We give you a written quote after a free in-home measure, and that number doesn’t move unless you change the job.
| Window Type | Typical Miami Beach Installed Cost |
|---|---|
| Impact windows (standard sizes) | $800 – $1,500 per window |
| Impact single-hung | $900 – $1,800 per window |
| Custom & geometric openings | $2,500 – $5,000 per opening |
| Whole-home impact package | $8,000 – $25,000+ |
Florida Pays You Back
The incentives stack if you know where to look. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact-resistant windows and doors are currently exempt from Florida sales tax. The federal 25C energy credit can return 30% of product cost, up to $600 per year on qualifying units. After installation, a wind mitigation inspection ($75 to $150) typically leads to windstorm premium credits averaging about 25% on the windstorm portion of your policy. We don’t guarantee those numbers, because your carrier and the program administrators set the final figures, but we’ll hand you the documentation packet any inspector or insurer asks for. Impact windows versus hurricane shutters: shutters only protect you if you’re home to hang them, and Miami Beach evacuations don’t wait. Permanent impact glass protects the building while you’re gone.

FAQs - Custom & Geometric Windows in Miami Beach
Yes, but impact rating alone isn’t enough. The Historic Preservation Board reviews the sightline, profile, and mullion configuration against the building’s original facade character. A fully HVHZ-compliant round window can still be denied on an Art Deco District building off Collins Avenue if it reads too modern. We’ve reprofiled custom units specifically to satisfy board reviewers while holding the Miami-Dade NOA intact. Call (727) 291-4678 before you buy anything, so you don’t pay for a window you can’t legally install.
Because Miami Beach enforces HVHZ structural review on every shaped unit, and a Florida Product Approval for the glass package doesn’t cover the frame profile if it wasn’t engineered for that exact configuration. The city requires a Miami-Dade NOA for the frame and mullion system as fabricated, not just the glazing. If a contractor submits a catalog arch window with a generic FL approval, the plan reviewer will kick it back. We pull NOAs for every custom profile before the first submittal.
Jalousie windows are prohibited in replacement installations under the current HVHZ code, so you can’t legally put jalousies back in. A custom geometric impact window is allowed as a replacement, but it must meet the design pressure of the original wall assembly and carry the proper Miami-Dade NOA for the new frame profile. Many North Beach rental owners don’t realize the code forces a full window conversation until the permit comes back. We handle that conversation all the time. Call (727) 291-4678 and we’ll tell you exactly what your building needs before you spend a dollar.
No. A NOA applies to a specific frame profile, glass package, and structural configuration as tested. When you build a custom radius mullion or a large geometric fixed unit, the engineered mullion package must be documented under its own NOA or an engineering analysis accepted by the city. This is the exact point where cheap quotes fall apart in Miami Beach, because the contractor priced the glass, not the engineering. We document every mullion, every anchor, and every design pressure calculation before we order the unit.
Your insurer wants evidence that the window was designed and installed to meet the wind load for your exact building location and floor height. A documented design pressure rating, matched to a Miami-Dade NOA and a passed permit inspection, gives the adjuster no room to argue that “inadequate” windows caused the damage. That’s what gets claims paid instead of litigated. We hand you the full packet at closeout: NOA, stamped drawings, inspection sign-offs. Call (727) 291-4678 for a free estimate and we’ll walk you through the exact path, from measure to permit to inspection to your insurance file.
The Miami Beach Approval Gauntlet No Other Page Will Explain
Miami Beach is the only place in the country where a shaped window has to satisfy Miami-Dade County’s HVHZ Notice of Acceptance requirements, the strictest impact-rated window and door codes in the nation, and clear the Miami Beach Historic Preservation Board’s design review if you’re in the Art Deco Historic District. A window can be fully HVHZ-compliant and still get rejected on a Collins Avenue building because its profile or sightline disrupts the original Art Deco facade. That dual-compliance gauntlet doesn’t exist in Coral Gables, doesn’t exist in Hialeah, and doesn’t exist in any neighboring municipality. This page is the only source that pairs Miami Beach’s dual HVHZ NOA and Historic Preservation Board requirements with the fabrication realities of arched, radius, and oversized openings, so you know exactly which documented ratings and sightline details your shaped window must carry before you buy.
Here’s what that looks like on the ground. On a mid-Beach 1960s concrete-block apartment off 63rd Street, our crew replaced a wall of corroded jalousie windows with custom impact-rated casement and oversized fixed geometric units from PGT. The original jambs had salt-spray pitting so severe we had to rebuild the rough openings before installing new Miami-Dade NOA frames with marine-grade coatings and stainless fasteners. The permit inspection passed on first look because the design pressure and large-missile rating documentation matched the stamped drawings exactly. That’s the difference between a quote that gets a window installed and a quote that just gets a window ordered.
