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 landing between $8,000 and $25,000 depending on opening count and frame material. Every unit we install in Miami carries a Miami-Dade NOA (Notice of Acceptance), because without that county-specific certification, your windows are not legal here and your insurance credits won’t apply. We’re Winslow Windows & Doors, and Ed Winslow’s name is on the door and on every job we do. Call (727) 483-7883 for a free in-home measure and a written, line-item quote.
Why Winslow Windows & Doors Is Miami’s Preferred Impact Windows Company
Miami is home to one of the most demanding building codes in the country, and we’ve spent years navigating exactly what that means for homeowners from Coconut Grove to Kendall. Our crews know the difference between a window that passes in Broward and one that passes in Miami-Dade, because the Miami-Dade NOA standard is stricter than Florida Product Approval and a lot of homeowners only find that out after a failed inspection. That local knowledge saves you from a tear-out-and-replace scenario that cheap bids leave out.
Ed Winslow founded this company in 2011 and he still answers the phone. When you call (727) 483-7883, a live person picks up, 24 hours a day. You won’t get a voicemail loop or a call center. You’ll get a straight answer about NOA numbers, design pressure ratings, and what your specific opening actually needs.
Every technician we send into a Miami home is background-checked and arrives in uniform. You’ll know who’s at your door before the truck pulls up. And every install carries our Done Right Promise: if it’s not done right, we make it right. That’s Ed’s word, and it covers every window, every door, every roof we touch.
We’re an authorized installer for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru. You get real product options matched to your wind zone and your budget, not a one-brand push. Our standing offers never expire: $40 off any repair over $200, free second opinions on written estimates, no trip charge inside Miami-Dade, and a permanent 10% discount for seniors and veterans.
Our Impact Windows Services in Miami
Impact Windows
Every impact window we install in Miami is selected and specified against the Miami-Dade NOA database before we ever order it. That means the unit’s design pressure rating, large-missile certification, and frame anchoring system are verified for your specific opening size and floor height. We don’t install windows that only carry Florida Product Approval in Miami, because doing so fails final inspection and forces a full tear-out. Our Impact Windows team handles single-hung, casement, horizontal roller, picture, and custom geometric openings, all matched to your home’s wind zone and exposure category.
Hurricane Protection
Miami sits in the High Velocity Hurricane Zone, which means impact-rated openings aren’t optional here. We spec large-missile-rated glass and frames that meet the Miami-Dade protocol for windborne debris, and we document every NOA number for your wind mitigation inspection. If you’re comparing impact windows against hurricane shutters, the difference is real: shutters require you to be home when the storm approaches, panels have to be stored and hung and taken down, and they do nothing for daily UV, noise, or energy loss. Impact windows are permanent protection that’s always in place, with no panels to hang and no storage to manage.
Miami-Dade NOA Compliance
The Miami-Dade Notice of Acceptance is the county’s own product approval system, and it exists on top of the statewide Florida Building Code. A window can be FBC-approved and still illegal to install in Miami city limits if it lacks the NOA. We verify the NOA number for every unit before ordering, we confirm the drawings match your opening dimensions and wind pressures, and we keep that documentation in your project file for your insurance carrier and any future sale of the home. A quote from a cheap installer often omits this step, and that omission is exactly what causes failed inspections.
Jalousie and Aluminum Window Replacement
Miami’s housing stock is packed with CBS homes from the 1950s through the 1980s, and a huge share of them still have original single-pane aluminum frames or jalousie windows. Jalousie panels can be popped out by hand with zero wind resistance, which is why Miami-Dade code prohibits them in new construction. Retrofitting these openings in existing masonry is specialized work: we fabricate steel buck assemblies, reinforce lintels where needed, and anchor the new impact frames into concrete block, which is a different job entirely from the wood-frame rough openings common in most other U.S. markets.

Trusted Brands We Service in Miami
Our Miami customers most often choose PGT for its deep catalog of Miami-Dade NOA-certified lines, Mr-Glass for window and door repairs that don’t require full replacement, and Therma-Tru for impact-rated entry doors that complement window upgrades. We carry local stock of common hardware and replacement parts so most repairs on these brands happen faster than ordering from out-of-state distributors. Because we’re an authorized installer, we can pull NOA documentation directly from manufacturer records and match it to your wind mitigation inspection paperwork.
Common Impact Windows Problems We See in Miami Homes
- Salt corrosion on standard aluminum frames. Homes near Biscayne Bay, the Miami River, and the coast deal with salt-laden air year-round. Non-marine-grade extrusions and hardware corrode within a few years, causing jamb binding and sash failure. We spec marine-grade anodized or vinyl-clad frames as the baseline for anything within a few miles of saltwater.
- Windows installed with Florida Product Approval but no Miami-Dade NOA. This is the most expensive mistake we fix in Miami. The window passes in Broward or Palm Beach, gets installed here, and then fails final inspection because Miami-Dade requires its own NOA. The fix is a full tear-out and replacement.
- Jalousie windows still in service on original 1960s homes. The louvers rattle, leak air, and provide zero impact resistance. Code prohibits them in new construction, and leaving them in place means losing any realistic shot at wind-mitigation insurance credits.
- Leaks around retrofit openings in concrete block walls. Improperly flashed or anchored retrofit frames let water into the block during Miami’s summer downpours. Correct installation requires buck fabrication, proper flashing, and anchor spacing matched to the NOA drawings, not generic rough-opening work.
Pricing for Impact Windows in Miami, FL
A standard impact single-hung window in Miami runs $900 to $1,800 installed, and a typical impact window overall lands between $800 and $1,500 per opening. Large or custom openings, like a wide picture window or a sliding glass door conversion, run $2,500 to $5,000. Whole-home packages typically start around $8,000 and can exceed $25,000 for larger homes with many openings or specialty geometry. What moves the price in Miami is opening count, frame material, floor height, and wind zone exposure. A second-floor window on a Biscayne Bay-facing elevation requires a higher design pressure than a first-floor window on an interior street, and that’s reflected in the NOA drawings and the unit cost. We quote fixed, line-item pricing with no change orders, and we never pad a quote to cover an inspection we didn’t plan for. Call (727) 483-7883 to schedule a free in-home measure and get a written quote with every NOA number listed.
What Impact Windows Cost in Miami
Impact windows in Miami generally run $800 to $1,500 per window installed, with impact single-hung units at $900 to $1,800 and large or custom openings at $2,500 to $5,000. Whole-home packages typically fall between $8,000 and $25,000-plus depending on opening count and frame material. The three things that move your price in Miami are the number of openings, the wind zone and floor height of each opening, and the frame material you choose. Aluminum is the most common choice here for its strength-to-weight ratio, but vinyl and vinyl-clad options perform better against salt air near the coast and often cost similar money once you factor in corrosion-resistant hardware. For the most accurate number, we do a free in-home measure and give you a written line-item quote. Call (727) 483-7883 to schedule yours.
Florida Pays You Back
The incentive stack for Miami homeowners is real, and every one of these programs requires documentation we provide as part of a compliant install. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows and doors are one of the covered improvements. Florida sales tax is currently exempt on impact-resistant windows and doors, which takes 6% or more off the top of your project. The federal 25C energy credit covers 30% of product cost on qualifying units, up to $600 per year. And the big one in Miami: windstorm-premium credits after a wind mitigation inspection average around 25% on the windstorm portion of your premium. The inspection itself runs $75 to $150. None of these are guaranteed, but they only become available when the windows carry the correct Miami-Dade NOA and the installation is documented properly. That’s exactly what we do.

FAQs - Impact Windows in Miami
A Miami-Dade NOA, or Notice of Acceptance, is the county’s own product approval document that certifies a specific window or door model and configuration has passed Miami-Dade’s wind-load and impact testing protocols. Every impact window and door installed in Miami must carry a Miami-Dade NOA, and windows approved only under statewide Florida Product Approval are not legal to install within city limits. Your final inspection will fail without the NOA, and your insurance wind-mitigation credits won’t apply. We verify the NOA number for every unit before ordering and document it in your project file. Call (727) 483-7883 for an exact quote, and we’ll show you the NOA documentation for the exact units we’re specifying.
Yes, but only with approval from the Miami Beach Historic Preservation Board, which reviews any exterior modification in the Miami Beach Architectural District. The board requires new units to replicate original sight lines, muntin profiles, and frame depths, which means custom-fabricated impact-rated windows that satisfy both HVHZ wind-load standards and the board’s aesthetic requirements. A standard off-the-shelf impact window installed without that approval triggers a stop-work order and a removal penalty. We’ve handled the paperwork and the custom sourcing for Art Deco and Mediterranean Revival homes throughout the district, and Miami Beach is one of the nearby cities we serve. Call (727) 483-7883 to talk through your specific property.
Your wind mitigation inspection documents the large-missile rating, design pressure, and Miami-Dade NOA numbers for every opening, and those three data points are what your insurance carrier uses to calculate premium credits. If the NOA numbers aren’t documented, or if the windows don’t carry the NOA at all, you get no credit. We provide a documentation package with every install that lists each unit’s NOA number, design pressure, and large-missile certification, so when the inspector shows up, everything they need is already in hand. Call (727) 483-7883 for a free estimate, and ask us to include the documentation package.
Design pressure, expressed as a number like DP 50 or DP 60, measures how much wind force a window can withstand before structural failure. Large-missile rating is a separate test where a 9-pound 2×4 is shot at the glass at 50 feet per second, twice, followed by cyclical wind-pressure testing. A window can have a high design pressure and fail large-missile, or pass large-missile and have a lower design pressure. In the HVHZ, Miami openings need both ratings, matched to your specific wind zone and floor height. We spec both on every unit and document them for your inspection.
Jalousie windows are prohibited in new construction under Miami-Dade code because the louvered glass panels can be popped out by hand and provide zero wind or impact resistance. Existing jalousie windows in older homes can remain until you replace them, but they won’t qualify for wind-mitigation credits and they’re a real liability in a storm. Replacing them in a CBS wall requires buck fabrication and proper anchoring, which is exactly the kind of retrofit work we handle. Call (727) 483-7883 if you’re ready to replace yours.
Miami’s Code Is Different. Your Windows Have to Be Too.
Every impact window and door installed in Miami must hold a Miami-Dade NOA, and windows approved only under statewide Florida Product Approval are not legal to install within city limits. That’s a stricter standard than in Broward or Palm Beach counties, and it’s the single most important thing a Miami homeowner needs to know before signing any window contract. The NOA isn’t a marketing badge. It’s the document that proves your specific window, in your specific size, at your specific floor height, passed Miami-Dade’s wind-load and impact testing. If it’s not there, your final inspection fails, and you’re paying twice.
In a 1960s CBS home off Coral Way, our crew replaced original jalousie windows with PGT impact-rated casement units carrying Miami-Dade NOA #19-1025. The existing openings had no lintel reinforcement, so we fabricated and installed new steel buck assemblies before setting the frames. Then we documented the large-missile rating for the homeowner’s wind mitigation inspection. That’s what a compliant quote includes: buck fabrication, lintel work, NOA documentation, and anchoring matched to the drawings. A cheap quote leaves those out, passes the savings on paper, and hands you a failed inspection.
If you’re comparing impact windows against hurricane shutters, think about how you actually live. Shutters mean panels in the garage, a ladder in the heat, and the hope that you’re home when the storm turns toward us. Impact windows are permanent protection that’s always in place. They stop windborne debris, cut noise and UV year-round, and reduce your cooling load in a climate where air conditioning runs ten months a year. That’s why Miami-Dade homeowners are replacing old windows even outside hurricane season: the insurance premium reduction alone often covers a meaningful share of the project cost over a few years.
