AfterFast, Reliable Custom & Geometric Windows Across Miami
Custom and geometric windows in Miami aren’t a style choice, they’re a structural commitment. Every arched transom, oversized trapezoid, or radius corner unit you put into a Miami home has to hold a Miami-Dade Notice of Acceptance (NOA) before it’s legal to install. We know the paperwork, the engineering, and the install side of that equation better than most because we’ve been doing exactly this work in neighborhoods from Little Havana to Edgewater for years. Call (727) 604-9322 and you’ll reach a live person who can talk through your opening, your elevation, and what it actually takes to get it done right in Miami-Dade County.
Why Winslow Windows & Doors Is Miami’s Preferred Custom & Geometric Windows Company
Ed Winslow founded this company in 2011 and put his name on it. That’s not marketing language, it’s how we operate. When a Miami homeowner calls about an arched window that’s leaking wind-driven rain through the jamb, Ed’s the one who reviews the job notes. When a Brickell condo board asks for a Fl Product Approval number and a Miami-Dade NOA on the same submittal, we don’t blink. We’ve done it. Our crews are background-checked and uniformed, and they’ve worked enough CBS homes in Hialeah and historic districts in Miami Beach to know what they’re walking into before the truck parks. Every job carries the Done Right Promise. If it’s not right, we make it right. Simple as that.
One more thing worth saying plainly: our phone is answered by a person, 24 hours a day, every day. No call centers. No next-business-day callback. A neighbor you can call at 2 a.m. and someone will actually answer.
Our Custom & Geometric Windows Services in Miami
When Miami homeowners search for Custom & Geometric Windows, they’re usually looking at one of four situations. We handle all of them, and we start every one with a fixed written quote before anything gets ordered.
Custom Impact Windows
A custom impact window in Miami is a different animal from a stock impact window. The glass package has to carry a large-missile rating that matches your wind zone, and the frame extrusion has to be certified under the Miami-Dade NOA, not just Florida Product Approval. We order these from CWS and other authorized brands with design pressures calculated for the specific opening and floor height, not a one-size-fits-all spec. Expect $2,800 to $4,600 per window for a true custom impact unit in Miami, depending on size and glass.
Geometric & Shaped Windows
Triangles, pentagons, parallelograms, rake walls with angled tops. These are common in Miami’s 1950s and 1960s CBS ranches, especially in Westchester and Miami Gardens, where the original jalousie panels are long past their useful life. We reframe the rough opening, order the custom shape, and most importantly, verify the NOA covers that exact configuration before we submit the order. Getting a geometric window engineered and approved takes four to six weeks. Getting it wrong because the NOA doesn’t cover the shape takes ten to fourteen weeks once you factor in the reorder.
Arched & Curved Windows
Arched windows are the signature of Miami’s Mediterranean Revival and Art Deco housing stock. A true radius arch in Miami-Dade means the top curve is either a fixed radius or a segmented arch, and both have to pass the HVHZ large-missile impact test. We’ve worked on arched windows in Coral Gables where the HOA wants the muntin profile to match the original 1938 millwork, and we’ve worked on Miami Beach projects where the Historic Preservation Board has to sign off on glass clarity before one dollar gets spent on fabrication. Lead time on a custom arched impact unit: five to six weeks. Board review: add two to three more.
Oversized Openings
Floor-to-ceiling glass walls, multi-slide door and window combinations, corner glass with no mullion. These are the jobs where Miami’s wind zone matters most. A 12-foot wide opening at grade is a different engineering problem than the same opening on the 20th floor of a Brickell tower. We coordinate with the structural engineer, the glazier, and the crane company if needed. A large or custom opening in Miami typically runs $2,500 to $5,000 per opening, and whole-home packages with multiple oversized units start around $8,000 and go up from there.

Trusted Brands We Service in Miami
We’re an authorized installer for eight premium brands, and on Miami custom work we lean heavily on CWS, ES Windows, and ECO Window Systems. These are manufacturers who understand coastal wind zones and who maintain active Miami-Dade NOA product lines for geometric, arched, and oversized configurations. We don’t stock parts for one or two generic brands and try to make them work for every opening. We order from the exact manufacturer whose product is certified for your specific shape, elevation, and exposure. That’s how you get a window that passes inspection on the first visit.
Common Custom & Geometric Windows Problems We See in Miami Homes
- Salt-air corrosion on non-marine-grade frames. On barrier island properties and anything within a mile of Biscayne Bay, standard aluminum frames pit and fail in five to seven years. Marine-grade aluminum and proper stainless hardware are not optional on Miami waterfront.
- Wind-driven rain intrusion around custom openings. Miami gets 60-plus inches of rain annually, and a lot of it arrives sideways at 50 mph. The flashing and sealant detail on a geometric window matters as much as the glass. We rebuild the rough opening and flash it before the unit goes in.
- Failed Florida Product Approval only installs. A window that’s legal in Orlando is not automatically legal in Miami-Dade. If a custom unit was ordered without Miami-Dade NOA paperwork, inspection fails and the unit has to come out. That’s a $4,000-plus mistake on a single opening.
- Original jalousie and single-pane sliding windows in 1950s-1970s CBS homes. Thousands of these are still in service across Little Havana, Hialeah, and Miami Gardens. None are impact-rated, none meet current HVHZ code, and most leak. Reframing those openings for modern custom geometric windows is some of the most satisfying work we do.
Pricing for Custom & Geometric Windows in Miami, FL
A custom impact window in Miami typically runs $2,800 to $4,600 per window installed. Custom geometric and shaped units fall in the same range, with true arches and curves pushing toward the top of it. Oversized openings run $2,500 to $5,000 each. Whole-home custom packages start around $8,000 and climb past $25,000 depending on how many openings and how much glass. What moves the price in Miami: the wind zone, the floor height, the opening size, the frame material, and whether the unit needs a Miami-Dade NOA for that exact configuration. Every quote we give is a fixed written line-item quote. The price doesn’t change once work starts.

FAQs - Custom & Geometric Windows in Miami
Florida Product Approval is a statewide standard. Miami-Dade NOA is stricter, and Miami-Dade County requires the NOA on every window and door, including custom geometric units. A product can pass statewide testing and still lack the additional Miami-Dade certification for wind load, impact, and structural performance under the High Velocity Hurricane Zone. If you order a custom window without the NOA, inspection will fail and you’ll either tear it out or pay for a reorder. We verify NOA coverage before we order anything, on every single opening. Call (727) 604-9322 if you’ve got an estimate from someone else and want a second opinion. It’s free.
Two approvals run in parallel. The product has to carry a Miami-Dade NOA, and the design has to clear the Miami Beach Historic Preservation Board. The Board reviews muntin profiles, glass clarity, and frame finish against the district’s 1930s-1940s aesthetic. We submit the product NOA with the Board application at the same time, because a denial after ordering burns five to six weeks and the deposit. We’ve coordinated this on Miami Beach jobs and we’ll walk you through the sequence before you commit a dollar.
Yes. When a Miami-Dade NOA-certified impact window is installed and verified through a wind mitigation inspection, Florida carriers commonly reduce the windstorm premium by around 20 to 45 percent. The inspection itself typically costs $75 to $150. We’ll provide the NOA documentation and installation records your inspector needs. The final credit amount is set by your carrier, not by us, and we won’t guarantee a specific dollar figure. Call (727) 604-9322 and we’ll talk through what your house qualifies for.
Because every unit is fabricated to order and engineered specifically for Miami-Dade HVHZ. The glass is laminated, the interlayer is tested for large-missile impact, and the frame is built to the shape and size of your opening. That’s four to six weeks of fabrication before the unit ships. The labor once the window arrives is usually one to two days per opening. The calendar is set by the glass plant, not by the crew, which is why we lock in pricing before ordering so nothing changes while you wait.
It corrodes. Salt-laden air off Biscayne Bay pits standard aluminum within five to seven years, and the corrosion starts at the corners and the weep holes, exactly where a geometric window has the most joinery. Add Miami’s rain volume and you get leaks around the sash within two seasons. Marine-grade aluminum, proper flashing, and stainless hardware are the floor for Coconut Grove waterfront work, not an upgrade. If you’re seeing white powder or pitting on your existing frames, it’s already started. Call (727) 604-9322 and we’ll do a free visual assessment.
What Custom & Geometric Windows Cost in Miami
Let’s give you real numbers. Standard impact windows in Miami run $800 to $1,500 per window installed. Single-hung impact units land between $900 and $1,800. Large or custom openings with geometric shapes, arches, or oversized glass run $2,500 to $5,000 per opening. Whole-home packages across a 1950s CBS house in Miami Gardens or a waterfront home in Coconut Grove start around $8,000 and climb past $25,000 depending on glass area, frame spec, and how many openings need reframing. What moves the price: the number of openings, the wind zone and floor height, the frame material (marine-grade costs more and is worth it on the water), and whether the opening needs structural reframing before the window goes in. We measure in person and give you a fixed written quote. The price on that quote is the price you pay. Call (727) 604-9322 to schedule your free in-home measure.
Florida Pays You Back
Miami homeowners have access to a few incentives that soften the cost of custom impact windows. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact windows. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit covers 30 percent of product cost up to $600 per year on qualifying energy-efficient units. And windstorm premium credits after a wind mitigation inspection typically average about 25 percent on the windstorm portion of your policy. Programs change and carriers set final numbers, so we won’t promise a dollar figure we can’t guarantee. But we’ll hand you the documentation and point you to the right applications. One comparison worth making: impact windows versus hurricane shutters. Shutters only work if someone is home to hang them, and they do nothing for intruders, noise, or daily energy costs. Permanent impact glass protects every day it’s installed, storm or no storm.
We rebuilt a 1950s CBS home in Little Havana where the original aluminum jalousie openings were collapsing from salt corrosion. The owner wanted real glass, real protection, and real light. Our crew reframed the openings for custom impact-rated geometric windows from ES Windows, with laminated glass interlayers and low-E coating. We pulled the Miami-Dade NOA paperwork and coordinated the historic review before the order was placed, so the design pressures and large-missile rating matched the wind mitigation requirements and the job held to the fixed written quote. That’s how custom work in Miami should go. That’s how we do it.
