Fast, Reliable Custom & Geometric Windows Across North Miami Beach
Custom and geometric window work in North Miami Beach is a different animal from anything you’ll find in Broward County. The city sits inside the High Velocity Hurricane Zone, which means every arched transom, porthole unit, radius window, and oversized fixed pane must carry a Miami-Dade Notice of Acceptance. We’ve been installing and replacing these windows across North Miami Beach long enough to know exactly what inspectors look for, what the salt air does to cheap frames, and how to open a 1950s concrete block wall without cracking it. If you’re pricing a custom window project in North Miami Beach, call (727) 483-7883 and we’ll give you real numbers, not ballpark guesses.

Why Winslow Windows & Doors Is North Miami Beach’s Preferred Custom & Geometric Windows Company
Ed Winslow started this company in 2011, and he still answers to his name on every job. Homeowners in North Miami Beach call us because they’ve learned the hard way that a window company from Fort Lauderdale or Miami Gardens may not know the first thing about HVHZ compliance on a geometric opening. We do. Our Custom & Geometric Windows team has handled enough North Miami Beach projects to tell you, before you sign, whether a radius unit will clear Miami-Dade NOA review, what the rough opening in your CBS wall actually looks like once we remove the old jalousie, and which frame material will hold up to Biscayne Bay salt air.
We also answer the phone. Not a call center, not a voicemail loop. A live person picks up 24/7. That matters when a storm is bearing down on North Miami Beach and you need a straight answer about whether your existing geometric glass is impact-rated. Ed’s name is on the door, and our published address and state license number are right there for anyone to check. No shell companies, no subcontractor roulette, no ticket numbers. Every technician who arrives at your North Miami Beach home is background-checked and in uniform, so you know who’s at your door before the truck stops.
Our Custom & Geometric Windows Services in North Miami Beach
Custom Impact Windows
A custom impact window in North Miami Beach means more than just ordering a nonstandard size. It means the unit must carry a Miami-Dade NOA for the exact configuration, the glass must pass large-missile impact testing, and the frame must be joined and sealed to survive decades of salt-laden wind off the Atlantic. We design and install true custom impact windows for openings that have no standard replacement on the shelf. If your 1960s CBS home still has the original single-pane aluminum sliders, you’re past due for an upgrade, and we’ll spec the NOA-compliant replacement from the start.

Geometric & Shaped Windows
Triangles, trapezoids, pentagons, portholes, half-rounds. North Miami Beach has a stock of mid-century homes with genuinely interesting glass, and most of it predates any impact standard. We build geometric windows to fit openings that were never square and never standard. The trick in North Miami Beach is paperwork as much as carpentry: every custom geometry needs a NOA or an engineered product approval that matches the opening dimensions and design pressure for your wind zone. We handle that end to end so you don’t get a failed inspection over a document.

Arched & Curved Windows
Arched windows over entryways and curved radius units in living rooms are common in North Miami Beach’s older single-family stock, and they’re among the most expensive windows to get wrong. An arched unit that would pass inspection in Hollywood or Davie will get red-tagged here if it lacks a Miami-Dade NOA. We’ll measure the exact radius, source the laminated impact glass, and set the frame so the miter joints stay tight. We also see a lot of arched windows with rotted wood bucks behind the stucco. We replace those with pressure-treated lumber sized to the new unit.

Oversized Openings
Big fixed panes, wide sliding glass walls, and full-height geometric windows look spectacular in North Miami Beach’s waterfront homes, but they need design pressures and glass deflection numbers that small window shops never calculate. Oversized impact openings carry the highest wind loads and the strictest HVHZ requirements. We handle the structural arithmetic, the NOA documentation, and the installation sequencing, so your 12-foot pane doesn’t bow or whistle during a September blow. These jobs take longer and cost more than swapping a bedroom window. We’ll tell you that upfront.

Trusted Brands We Service in North Miami Beach
We’re an authorized installer for eight premium window and door brands, and for custom and geometric work in North Miami Beach we most often specify ECO Window Systems, Mr-Glass because their engineering and NOA paperwork are solid and predictable. We also install PGT and CGI products where the opening calls for them. Every custom unit we order for North Miami Beach is fabricated to the measured opening and the required design pressure. That means no field modifications that would void a NOA, and no “close enough” shimming. The custom fabrication window runs four to six weeks once we finalize your measurements, and once the units arrive they can be installed in as fast as a single day.
Common Custom & Geometric Windows Problems We See in North Miami Beach Homes
- Salt corrosion at the frame corners. Standard zinc-plated fasteners and unanodized aluminum frames start pitting within two or three seasons this close to Biscayne Bay. You’ll see white blooms at the miter joints first. We specify marine-grade or properly anodized aluminum and stainless or hot-dip galvanized hardware on every North Miami Beach job.
- Non-NOA impact glazing that fails HVHZ inspection. We’ve replaced brand-new arched windows in North Miami Beach that a Broward contractor installed with Florida Product Approval glass. It doesn’t matter how clean the trim looks. If the unit doesn’t carry a Miami-Dade NOA, it fails and has to come out.
- Improperly sealed custom-shaped openings. Driving rain at a jamb or sill joint gets behind the CBS wall, spalls the concrete over time, and creates a hidden path for termites. North Miami Beach’s hurricane season turns a small caulk void into a structural problem fast. We seal and flash every custom opening to the specifics of the wall assembly.
- Jalousie frames mortared directly into concrete block. In the older North Miami Beach neighborhoods around Skylake and Ives Dairy Road, we routinely find original jalousie frames set straight into the block with no conventional rough opening. Pulling them without cracking the masonry, then building a compliant pressure-treated buck, is a skill set that catches Broward crews off guard.
Pricing for Custom & Geometric Windows in North Miami Beach, FL
North Miami Beach pricing reflects the HVHZ code, the salt-air material requirements, and the reality of nonstandard CBS rough openings. Impact windows in this market generally run $800 to $1,500 per window installed. A custom or oversized opening starts around $2,500 and can reach $5,000 or more depending on glass area, design pressure, and geometry. Whole-home packages in North Miami Beach land between $8,000 and $25,000 or higher for large custom jobs. What moves the price most is opening count, wind zone (everything here is HVHZ, but window elevation and exposure change the required design pressure), frame material, and whether we need to saw-cut a new opening or rebuild a rotting buck. Salt-air marine finishes and stainless hardware add cost too, and they’re not optional here. Call (727) 483-7883 for a free in-home measure and a written line-item quote. Upfront pricing, no surprises on the invoice.

What Custom & Geometric Windows Costs in North Miami Beach
Let’s put real numbers on the page. A standard impact single-hung in North Miami Beach runs $900 to $1,800 installed. A fixed geometric or radius unit, especially one that requires a custom NOA product approval, runs $2,500 to $5,000 installed. Whole-home impact packages typically fall between $8,000 and $25,000 or more, depending on the number of openings and how many are nonstandard. The largest driver of North Miami Beach cost is the opening itself. A 1950s CBS wall with a jalousie frame mortared into the block needs saw-cutting, a new pressure-treated buck, and often masonry repair before the new window goes in. An experienced crew will factor that into the quote from day one. A crew that doesn’t will “discover” it mid-job and hand you a change order. We don’t work that way. Call (727) 483-7883 and we’ll measure, itemize, and give you a fixed written quote.
Florida Pays You Back
North Miami Beach homeowners can stack several incentives on custom impact window work. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and North Miami Beach homes inside the HVHZ are exactly the houses the program was built for. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit can return 30% of the product cost, up to $600 per year, on qualifying efficient units. After a wind-mitigation inspection, which runs roughly $75 to $150 in this market, many North Miami Beach homeowners see windstorm-premium credits averaging around 25% on the wind portion of their policy. Programs and carriers set the final numbers, so we’ll point you to the right paperwork and let you confirm the details with your insurer. We won’t promise a dollar figure that isn’t ours to promise.

FAQs - Custom & Geometric Windows in North Miami Beach
A NOA is required, not optional. North Miami Beach is entirely inside Miami-Dade County’s High Velocity Hurricane Zone, and every window or door replacement must carry a Miami-Dade Notice of Acceptance. A Florida Product Approval, which passes in Broward cities like Hollywood or Fort Lauderdale, will not clear inspection here. If a contractor tells you otherwise, hang up. Call (727) 483-7883 and we’ll spec NOA-compliant units from the first drawing.
We saw-cut the block carefully, remove the old jalousie frame without cracking the surrounding masonry, then build and seal a pressure-treated buck sized to the new geometric window. In practice, we recently opened a 1950s CBS house off Ives Dairy Road where a porthole-style window had been mortared directly into the block with no rough opening at all. Our crew cut the opening clean, built the buck, and set a PGT custom radius impact-rated unit with a laminated interlayer and a large-missile rating that now carries a Miami-Dade NOA. That’s the standard process, and it’s why we quote these jobs accurately the first time.
Marine-grade or properly anodized aluminum is the right call this close to Biscayne Bay. Salt air pits standard zinc-plated fasteners and raw aluminum within a few seasons, and you’ll see white corrosion blooms at the miter joints of a custom geometric window before you’ve owned it three years. We also use stainless or hot-dip galvanized hardware. Vinyl can work for interior-facing installs, but for a coastal custom window we’d rather spec a frame we know will still look tight in a decade. Call (727) 483-7883 and we’ll walk you through the options with real numbers.
We schedule from our Miami (South FL) office, and our crews serve North Miami Beach daily. For a custom window measure in Skylake, Eastern Shores, or the Ives Dairy Road corridor, we can typically get a technician to you within a day or two of your call. Once your custom units are fabricated, which runs four to six weeks, installation can often be completed in a single day. Call (727) 483-7883 and a real person will get you on the schedule.
No. We give you a written line-item quote before work begins, and we stand behind it. The one place where hacks make their money in North Miami Beach is the surprise change order after they discover a rotted buck or a nonstandard rough opening mid-install. We anticipate those conditions because we know this housing stock. The price we quote is the price you pay. If you already have a written estimate from another company, bring it in and we’ll give you a free second opinion. Call (727) 483-7883.
