Custom & Geometric Windows in Miami - Free In-Home Measure, Written Price

Fast, Reliable Custom & Geometric Windows Across Miami

Custom and geometric window work in Miami isn’t a standard window replacement with a different label on the box. It’s engineering a specific shape into a specific opening on a specific house, then proving to Miami-Dade County that the finished assembly will hold up in a hurricane. A circle-top transom, a true radius casement, a trapezoid picture window facing Biscayne Bay: every one of these needs a Miami-Dade Notice of Acceptance (NOA) tied to the exact glass cut and frame profile, or the inspector fails it. We deliver that. Call (863) 251-5864 and Ed Winslow’s team will measure, spec, and install it right.

We’ve worked the neighborhoods from Little Havana to North Miami to Coral Gables long enough to know that a geometric window on a 1940s Mediterranean Revival is a completely different job from the same shape on a 1980s CBS rancher. The difference isn’t just aesthetics. It’s permitting, anchoring, flashing, and product selection. We plan for all of it before the first cut.

Why Winslow Windows & Doors Is Miami’s Preferred Custom & Geometric Windows Company

Ed Winslow founded this business in 2011, and he still answers the phone. That matters in a city where a lot of window companies are call centers routing to subcontractors. Our Miami customers get a published address, a license number, and a live person on the phone 24/7. You call at 2 a.m. with water coming through a failed custom transom, a real person picks up. Not a voicemail tree.

Every technician who shows up in Miami is background-checked and in uniform. You know the name before the truck parks. Our installation crews work with eight authorized brands including PGT, CGI, ES Windows, ECO Window Systems, Mr Glass service in Miami, and Therma-Tru. We don’t push whatever’s easiest to source. We spec the product that matches the opening, the wind zone, and the look you’re preserving or creating.

And when Miami-Dade inspectors review our work, the NOA number is on the paperwork before the window is ordered. Because we’ve seen what happens when it isn’t: a failed inspection, a reorder, and a homeowner with an open hole during hurricane season.

Our Custom & Geometric Windows Services in Miami

Here’s the reality of Custom & Geometric Windows: in most of the country, these are novelty upgrades. In Miami, they’re structural decisions regulated by the toughest building code in the continental U.S. These are the four services we handle most often across Miami.

Custom Impact Windows

A custom Impact Windows in Miami is not an off-the-shelf product with a bigger price tag. It’s a large-missile-rated laminated glass unit, a reinforced frame, and a NOA that covers that exact combination. We handle large picture windows, radius shapes, and openings where a standard rectangle won’t work. We verify the NOA before we order, because Miami-Dade doesn’t accept Florida Product Approval alone on non-standard shapes.

Geometric & Shaped Windows

Triangles, trapezoids, pentagons, ovals, eyebrows. Miami’s custom home builders and renovators use these shapes constantly, especially on modern concrete structures along the bay. Each shape carries its own design pressure rating and its own product approval number. We match the shape to the structural opening and then confirm the county paperwork lines up. If the manufacturer’s NOA doesn’t cover a specific cut, we find that out before your deposit is spent, not after a failed inspection.

Arched & Curved Windows

Arched windows are the single most common custom request we get in Coral Gables and the older neighborhoods around it. A true radius top on a Mediterranean Revival home isn’t a decorative add-on. It’s a structural radius on a masonry opening. We’ve built these to match original divided-lite muntin profiles while hitting modern HVHZ impact standards. That’s the specialty here.

Oversized Openings

A 12-foot arch facing the water. A floor-to-ceiling trapezoid on a modern CBS home in North Miami. Openings this size need engineering review, reinforced framing, and often a crane lift. We scope the framing and the glass package together, because the wind load on a 12-foot span within a mile of Biscayne Bay is an entirely different calculation than what a stock window is rated for.

Trusted Brands We Service in Miami

We’re authorized installers for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux, offering Shingle, Tile & Metal Roofing - Miami as well. For Miami coastal work, we lean heavily on CGI and PGT for impact-rated custom shapes, and ES Windows for high-end architectural radius work where the finish matters as much as the rating. We stock local access to parts and hardware for these brands, so warranty service in Miami doesn’t mean a six-week wait on a truck from out of state. When a salt-air-corroded sash component fails on a bayfront installation, we get the replacement from inventory or direct from the manufacturer fast. You don’t live with a taped-up window.

Common Custom & Geometric Windows Problems We See in Miami Homes

• Non-rectangular shapes without Miami-Dade NOAs: A triangular transom over a door can pass Florida Product Approval but lack the county-specific NOA. The inspector flags it, the window fails, and the homeowner reorders and waits six to eight weeks. We verify NOA numbers at the quote stage, not at the inspection.
• Salt-air hardware failure in bayfront openings: Any custom window within a mile of Biscayne Bay or the Atlantic needs marine-grade hardware and a reinforced finish on the frame. Standard aluminum sash hardware oxidizes fast, and once the hardware goes, the impact-rated glazing seal is compromised. We spec marine-grade components on every coastal job.
• Jalousie replacements on pre-Andrew homes: Hialeah, Little Havana, and North Miami are full of 1950s and 1960s CBS homes with original jalousie windows. They offer zero hurricane resistance and insurance carriers are forcing replacements. Custom geometric impact windows solve the code and insurance problem, but the masonry openings often need re-bedding before the new frame goes in.
• Coral Gables divided-lite conflicts: Replace a divided-lite window on a Coral Gables landmark home without City Beautiful Board pre-clearance, and you risk a stop-work order. The window has to match the original muntin profile and get board approval before fabrication. We handle that paperwork path from day one.

Pricing for Custom & Geometric Windows in Miami, FL

What Custom & Geometric Windows Costs in Miami

Here are the working ranges we quote from every week. Impact windows generally cost $800 to $1,500 per window installed. A single-hung impact unit runs $900 to $1,800. Large or fully custom openings in the geometric category land at $2,500 to $5,000 each. Whole-home packages with custom and geometric shapes start around $8,000 and go beyond $25,000 on high-wind-zone coastal properties.

What actually moves the number in Miami? Opening count first. Then wind zone: a bayfront home within a mile of open water carries a higher design pressure requirement than an interior lot in Westchester. Floor height matters too, because upper-floor openings catch more wind load. Frame material changes the price: vinyl is the budget path, aluminum the standard for coastal corrosion resistance, and wood-clad only where a historic overlay requires it. We give you a written line-item quote after a free in-home measure, and the number on that quote is the number you pay. No change orders unless the opening itself turns out to be structurally different than what we measured.

Florida Pays You Back

Florida’s incentive programs are real, and they stack. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and custom impact windows qualify. Florida also exempts impact-resistant windows and doors from sales tax. At the federal level, the 25C energy credit covers 30% of the product cost on qualifying units, up to $600 per year. And once your home passes a wind-mitigation inspection ($75 to $150), most Miami carriers cut the windstorm portion of your premium by around 25% on average. These aren’t guarantees from us. The state sets the grant terms, your insurer sets the final premium numbers, and your accountant sets the tax credit. But we supply the product documentation and the NOA paperwork that makes all of it possible.

One more thing worth knowing: impact windows beat hurricane shutters for a Miami homeowner who wants permanent protection without panels to hang at 11 p.m. before a storm makes landfall. Shutters only work if someone installs them. Impact windows are always on. And they qualify for the same insurance credits.
