AfterFast, Reliable Impact Windows Across Miami
Impact window installation in Miami typically runs $800 to $1,500 per window for standard openings, with whole-home packages starting around $8,000. Every window we install in Miami carries a Miami-Dade Notice of Acceptance (NOA), because a Florida Statewide Product Approval alone will fail inspection here. That’s the paperwork reality most homeowners don’t learn until the inspector shakes his head. We know it before we order your first unit.
Ed Winslow has had his name on this business since 2011, and that matters when you’re spending this kind of money. Call (844) 901-4551 and a live person picks up, any hour, any day. Not a call center. Not a voicemail box. We serve the entire Miami metro including Coral Gables, Kendall, Cutler Bay, and the neighborhoods along US-1 and the Palmetto Expressway.
Why Winslow Windows & Doors Is Miami’s Preferred Impact Windows Company
We’re the local alternative to the national chains that treat Miami like any other market. Miami isn’t any other market. Ours is a High Velocity Hurricane Zone with its own product approval system, its own inspection standards, and its own salt-air corrosion problems that inland installers have never seen.
Our Miami customers keep coming back because we do the paperwork right the first time. Before we order a single window, we confirm the Miami-Dade NOA matches the exact configuration going into your opening. An out-of-market crew learns that lesson at inspection, when the window they installed in Tampa three weeks ago gets red-tagged on a Miami jobsite. We learned it years ago, and we built our entire Miami process around it.
Every technician who arrives at your Miami home is background-checked, uniformed, and works for Winslow directly, not a subcontractor we found on a gig app. Ed’s name is on the door, and on every job we do.
We’re proud to be the Impact Windows team Miami homeowners call when they want it done once, correctly, with documentation that passes inspection and actually lowers their windstorm premium.
Our Impact Windows Services in Miami
Miami-Dade NOA Product Verification & Permit Documentation
This is the service nobody else in Miami advertises, and it’s the one that saves you the most money and stress. Before ordering product, we verify the Miami-Dade NOA for your exact window configuration, including size, design pressure rating, and frame material. Then we prepare the permit documentation so the inspection goes through on the first visit. A failed inspection means another day off work and another scheduling cycle. We prevent that before it starts.
Masonry Anchoring for Concrete Block (CBS) Openings
Most Miami homes built from the 1950s through the 1980s are CBS construction: concrete block with stucco. Anchoring an impact window into masonry is a fundamentally different skill than screwing into wood studs, which is what installers do in most of the country. Our crews anchor directly into the block using fasteners and techniques matched to the wind load, the block condition, and the height of the opening. Get this wrong and the window blows out of the wall during a storm, frame and all.
Salt-Air Corrosion-Resistant Hardware & Sealant Upgrades
Miami’s proximity to Biscayne Bay and the Atlantic means salt-laden air eats aluminum frames, hardware, and sealants year-round. We specify marine-grade finishes and stainless or hot-dip galvanized hardware on every coastal job. Non-marine hardware fails in five to seven years here. You can buy the cheaper spec, or you can buy it once. We stock the right materials for Miami’s environment because we work in it every day.
Full Replacement of Jalousie & Single-Pane Windows
Older Miami neighborhoods like Little Havana, Allapattah, Brownsville, and parts of Miami Beach still have jalousie windows, the louvered glass slats that provide zero hurricane protection and fail any wind mitigation inspection. We remove them entirely, reframe and seal the masonry opening, and install fully impact-rated units with large-missile certification. This is a code-compliance upgrade and an insurance-premium reduction in one job.

Trusted Brands We Service in Miami
We’re an authorized installer for CGI, CWS, and ES Windows, and we maintain local parts inventory so Miami customers aren’t waiting on a shipment from a warehouse in another state. Every unit we install comes with documentation matching its exact Miami-Dade NOA or Florida Product Approval number by configuration. We don’t sell generic glass with a hurricane sticker. We sell PGT, CGI, and the other brands we’ve built our reputation on since Ed founded the company in 2011.
Common Impact Windows Problems We See in Miami Homes
- Corroded aluminum frames near Biscayne Bay: Salt-laden air eats non-marine finishes in five to seven years, causing sash binding and seal failure. We see it on nearly every coastal inspection we do in Coconut Grove and Key Biscayne.
- Jalousie windows that fail wind mitigation inspections: These louvered-glass units provide no large-missile protection and automatically block insurance credits. Full replacement is the fix, and it’s the most common upgrade we perform in Little Havana and Hialeah.
- Salt-degraded sealants allowing wind-driven rain intrusion: Once the seal at the jamb fails, Miami’s summer thunderstorms push water directly into the drywall. Quiet damage, expensive repair. We replace with marine-grade sealants that hold up to salt spray and UV.
- Windows without a Miami-Dade NOA installed by out-of-market crews: A Florida Product Approval is not enough in Miami-Dade. We’ve had homeowners call us after another company installed windows that failed inspection because the paperwork didn’t match local requirements. We fix it, but it’s a costly lesson that never needed to happen.
Pricing for Impact Windows in Miami, FL
Standard impact windows in Miami run $800 to $1,500 per unit installed. Single-hung impact windows land between $900 and $1,800. Large or custom openings, the kind you see in waterfront homes or mid-century modern properties, can run $2,500 to $5,000 each. Whole-home packages typically start around $8,000 and go up from there depending on opening count, frame material, and floor height, which affects design pressure requirements.
What moves the price in Miami specifically: opening count, whether the home is in the HVHZ, how high the windows sit, and whether you choose standard aluminum or a marine-grade finish. The coastal-spec version costs more up front, 10 to 20 percent typically, and it avoids the five-to-seven-year corrosion replacement that the inland-spec version guarantees.

What Impact Windows Costs in Miami
Let’s put harder numbers on it. Most Miami homeowners replace between five and twelve openings. A five-window job on a single-story CBS home in Westchester might run $4,000 to $7,500. A twelve-window job on a two-story home in Pinecrest with large custom openings could exceed $25,000. The variables are real: frame material, glass package, whether you need tempered or laminated glass per opening, and the design pressure rating required by your wind zone and exposure category.
We give you a written, line-item quote before you commit to anything. No change orders after the fact, no “we found rot and need another $4,000” phone calls. Free in-home measure, free quote, and a free second opinion on any written estimate you’ve received from another company. Call (844) 901-4551 to schedule yours.
Florida Pays You Back
Miami homeowners have access to real incentives that make impact windows easier to justify. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact windows and doors. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit can return 30 percent of product cost, up to $600 per year, on qualifying energy-efficient units. And after a wind-mitigation inspection, which typically costs $75 to $150, most Miami homeowners see their windstorm premium drop by around 25 percent.
Program details and carrier calculations are controlled by the state and your insurer, not by us. But we prepare the documentation properly so the credits you qualify for actually land. One Little Havana homeowner we work with saw her annual premium drop by nearly $900 after replacing eight jalousie windows with fully impact-rated CGI units and passing her first wind mitigation inspection in twenty years.
One note on comparison: impact windows beat hurricane shutters for most Miami homeowners because the protection is permanent. No panels to drag out of a storage room at the last minute, no tracks corroding in the salt air, no forgetting to close them before you evacuate. The upfront cost is higher, but the premium credit applies every year, and the window is always working.

FAQs — Impact Windows in Miami
A Miami-Dade Notice of Acceptance is a stricter product-testing protocol than the statewide Florida Product Approval system, and it’s required for every replacement window and door in Miami-Dade County. A Florida Product Approval alone will fail inspection here even though the same window is legal in Tampa or Sarasota. Before we order any unit for your home, we verify the NOA matches your exact configuration, size, and design pressure rating. Call (844) 901-4551 and we’ll check your existing paperwork for free.
Salt-laden air accelerates corrosion on aluminum frames, hardware, and sealants, so homes within a few miles of Biscayne Bay or the Atlantic need marine-grade finishes and stainless or hot-dip galvanized hardware to avoid sash binding and seal failure within five to seven years. Standard inland-spec frames cost less up front but often need replacement within a decade in Miami’s coastal environment. We quote both options and show you the real cost difference so you can decide with full information.
Yes, in most cases. After a wind-mitigation inspection, which typically costs $75 to $150, fully impact-rated windows and doors commonly reduce the windstorm portion of a Miami homeowner’s premium by roughly 25 percent. The exact credit depends on your insurer and policy, but the documentation has to be correct, and that’s the part we handle. We’ll prepare the NOA paperwork and installation documentation your inspector needs to sign off.
Jalousie windows cannot be retrofitted to meet Miami-Dade impact requirements. They provide zero large-missile protection and fail any wind mitigation inspection automatically. Full replacement with impact-rated units is required, and it’s one of the most common upgrades we perform in Little Havana, Hialeah, and other older Miami neighborhoods with 1950s-to-1970s CBS construction. We saw a row of original jalousie windows on a 1960s home in Little Havana where the aluminum jambs had corroded through from decades of Biscayne Bay salt spray, leaving the interlayer fogged. Our crew anchored new PGT double-hung units into the concrete block openings and sealed the rough openings with marine-grade sealant. The homeowner passed her first wind mitigation inspection on the first attempt.
A large-missile rating means the window was tested to withstand impact from a nine-pound two-by-four traveling at 34 miles per hour, the standard that simulates wind-borne debris during a major hurricane. Miami’s position at the tip of the Florida peninsula places it in the most hurricane-exposed corridor in the continental U.S., and the HVHZ designation requires large-missile protection on all windward openings. Inland Florida cities face lower wind loads and don’t have the same mandatory requirement, which is why a window legal in Orlando may not pass inspection here. Every unit we install in Miami carries the large-missile certification required by your opening’s design pressure calculation.
