Fast, Reliable Window Replacement Across Miami
Window replacement in Miami means something different than it does anywhere else in the country. Miami-Dade County sits entirely inside Florida’s High-Velocity Hurricane Zone (HVHZ), the strictest window-and-door code jurisdiction in the United States. Every replacement opening must carry a Miami-Dade Notice of Acceptance (NOA), a certification tier that many nationally-sold brands never bother to obtain. If the window you’re buying can’t produce one, it won’t pass inspection here, period. Winslow Windows & Doors has installed NOA-compliant impact windows across Miami since 2011, and we’re the team homeowners call when they want the job done right the first time.

Miami customers consistently tell us the same thing: the quote we give is the price they pay. No change orders, no surprises on the invoice. We offer a free second opinion on any written estimate, and there’s no trip charge inside Miami-Dade County. If you’re a senior or veteran, you’ll get a permanent 10% discount on every job.

Our Window Replacement Services in Miami
Every window we install in Miami is a hurricane-compliance job first. That’s the reality of HVHZ code, and it shapes every service we offer. Here’s what Miami homeowners call us for most.
Full Frame Replacement
Full frame replacement removes the entire existing window assembly, including the frame and jamb, down to the rough opening. In Miami’s older concrete block homes across Hialeah, Kendall, and Little Havana, this is often the only correct approach. The original aluminum frames from the 1950s and 1960s are corroded from decades of salt air off Biscayne Bay, and reusing them compromises the new window’s design pressure rating. A full frame replacement in Miami means fresh framing, proper flashing and sealant, and an installation that actually meets the NOA’s structural requirements.

Insert Window Replacement
Insert replacement, sometimes called pocket replacement, fits a new window unit inside the existing frame. It works well in Miami when the current frame is still structurally sound and square. That’s more common in newer construction, particularly in Brickell and along the Miami Beach corridor, where buildings from the 1990s and later often have frames worth saving. We’ll tell you honestly whether an insert makes sense for your opening or whether a full frame is the smarter move. Salt air corrosion is the deciding factor more often than homeowners expect.

Vinyl Replacement Windows
Vinyl replacement windows are the most popular choice in Miami for good reason. Marine-grade vinyl resists the salt corrosion that eats aluminum frames along the bay and coast, and it takes impact-rated glass beautifully. We install vinyl units from PGT and CGI, both with full Miami-Dade NOA documentation for HVHZ compliance. For the typical CBS ranch home in West Miami or Coral Gables, a vinyl impact window gives you hurricane protection, energy efficiency, and a frame that won’t pit or oxidize in the salt air.

Energy-Efficient Upgrade
Miami’s sun is relentless, and your AC bill feels it every month. Energy-efficient replacement windows with low-E coatings and insulated glass cut solar heat gain through the glass itself, which matters enormously in a city where east- and west-facing openings bake all day. Pair an energy-efficient upgrade with impact rating and you get two benefits at once: lower cooling costs and windstorm premium credits after your wind mitigation inspection. That’s what a smart Miami window replacement looks like.

Trusted Brands We Service in Miami
We’re authorized installers for eight premium window and door brands, and in Miami we lean heavily on the three that dominate HVHZ work: PGT, CGI, and Therma-Tru. PGT and CGI impact windows carry the Miami-Dade NOA documentation Miami requires on every opening, and Therma-Tru doors meet the same standard for entry and patio applications. Because we install these brands daily across Miami, we know their product lines, their lead times, and their documentation requirements inside out. When your permit package needs NOA and Florida Product Approval numbers pulled for each unit, we handle it. Call (727) 620-6983 and we’ll walk you through which brand fits your home and your opening.
Common Window Replacement Problems We See in Miami Homes
- Corroded aluminum frames from salt air. Homes near Biscayne Bay, the Atlantic coast, and even along the Miami River deal with accelerated oxidation that pits and weakens aluminum frames within a decade or two. Reusing a corroded jamb on a new impact window is a shortcut that fails inspection and leaks during the next storm.
- Original jalousie windows still in place. Thousands of homes in Hialeah and older Miami neighborhoods still have louvered glass panels that provide zero hurricane resistance and are explicitly prohibited under HVHZ code for any new or replacement installation. Many homeowners don’t realize these windows can make them uninsurable under current Citizens Insurance underwriting rules.
- Windows with Florida Product Approval but no Miami-Dade NOA. A window can be legal in Tampa or Orlando and completely non-compliant in Miami. If a contractor installs a unit without a Miami-Dade NOA here, the opening fails HVHZ review and you’re left with an unpermitted window. We see this happen often enough that we check the documentation before we recommend any product.
- Skipped wind mitigation inspections. You can install impact windows correctly and still miss the insurance credit if the final wind mitigation inspection never happens. That inspection documents every opening as large-missile rated, and without it, Citizens and private carriers won’t apply the windstorm premium credit you earned.
Pricing for Window Replacement in Miami, FL
Window replacement in Miami runs higher than most of Florida because HVHZ compliance is mandatory, not optional. A typical impact-rated vinyl window in Miami costs between $800 and $1,500 installed. Impact single-hung units run $900 to $1,800. Large or custom openings, including oversized sliders and picture windows, land between $2,500 and $5,000. Whole-home packages for an average three-bedroom Miami home typically fall between $8,000 and $25,000. What moves the price: the number of openings, your wind zone, floor height, and frame material. Custom fabrication runs four to six weeks; once your units arrive, installation is often done in as fast as a single day. The estimate is free, and it’s a written line-item quote. Call (727) 620-6983 to schedule yours.
What Window Replacement Costs in Miami
Let’s be direct about the numbers. Impact windows in Miami run $800 to $1,500 per window installed, with impact single-hung units at $900 to $1,800. Large or custom openings, like a picture window facing the bay or a wide slider on a Brickell balcony, cost $2,500 to $5,000 each. Whole-home packages start around $8,000 and can exceed $25,000 depending on opening count and product choices. What moves the price in Miami specifically: your wind zone (coastal frontage costs more than inland), floor height (upper floors need higher design pressures), frame material (marine-grade vinyl and aluminum cost differently), and whether you’re doing insert or full frame replacement. We give you a free in-home measure and a written quote with every NOA number pulled before you sign anything.
Florida Pays You Back
Miami homeowners have several programs that offset window replacement costs. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which includes impact windows in many cases. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit gives you 30% of product cost back, up to $600 per year, on qualifying energy-efficient units. After installation, a wind mitigation inspection ($75 to $150) typically unlocks windstorm premium credits averaging around 25% on the windstorm portion of your policy. Programs and carriers set the final numbers, so we can’t guarantee amounts, but we’ll document every opening so you can claim what you qualify for.
One comparison worth making: impact windows versus hurricane shutters. Shutters protect openings only when someone is home to deploy them, and they do nothing for daily light, UV damage, or energy costs. Impact windows are permanent protection, no panels to hang, no decisions to make when a storm is 48 hours out. In Miami, where hurricane prep is a way of life, that permanence matters.

FAQs - Window Replacement in Miami
Miami-Dade requires an NOA because the entire county sits inside the High-Velocity Hurricane Zone, the strictest window-and-door code in the country, and the NOA is the document that proves a window has been tested to withstand Miami’s specific wind and debris loads. If you buy a window without a Miami-Dade NOA and install it anyway, the opening fails HVHZ review and you’re left with an unpermitted installation. That can block a home sale, trigger insurance issues, and leave the opening unprotected in the next storm. Call (727) 620-6983 and we’ll verify NOA documentation on any window you’re considering.
You must go impact-rated. Jalousie windows are explicitly prohibited under HVHZ code for any new or replacement installation in Miami-Dade, which means there is no legal non-impact replacement option. In Hialeah and older Miami neighborhoods, thousands of homes still have these louvered glass panels, and many homeowners don’t realize they’re uninsurable under current Citizens Insurance underwriting rules until they file a claim or try to renew a policy. We convert jalousie openings to impact-rated windows frequently, and we pull every permit and inspection along the way.
A documented impact window replacement, verified by a wind mitigation inspection, typically qualifies you for windstorm premium credits on the windstorm portion of your policy, averaging around 25% after the inspection. The key word is documented. The inspection must verify each opening as large-missile rated, and the NOA numbers and Florida Product Approval numbers must match the units installed. We provide all that documentation as part of the job. Call (727) 620-6983 for a free estimate and we’ll explain exactly what your home needs.
A Florida Product Approval is the statewide certification that a window meets Florida Building Code standards for impact resistance. A Miami-Dade NOA is a stricter, county-specific certification that tests for higher wind loads and confirms compliance with HVHZ requirements. In Miami, you need both. A window with only a Florida Product Approval fails HVHZ review and cannot be legally installed in Miami-Dade County. We only install units that carry both documents, and we include the numbers in your permit package.
If the frames are pitted and corroded, you need a full frame replacement. Salt corrosion weakens the structural integrity of the jamb, and reusing a corroded frame on a new impact window compromises the design pressure rating and creates leak points during the next storm. We see this constantly in bayfront and oceanfront homes in Miami, where aluminum frames can show visible corrosion within a decade. A full frame replacement gives you fresh framing, proper flashing, and a window that actually performs to its rating. Call (727) 620-6983 and we’ll inspect your frames honestly.
The Miami Code Reality Most Guides Skip
Miami-Dade County is the only U.S. jurisdiction where every replacement window must carry a Miami-Dade Notice of Acceptance, because the county sits entirely within the High-Velocity Hurricane Zone. This regulatory layer, written in response to the glazing failures exposed by Hurricane Andrew in 1992, means every window job in Miami is legally a hurricane-compliance job first. Product selection, permitting, and installation are fundamentally different here than anywhere else in the country. A window that’s perfectly legal in Jacksonville will fail inspection in Kendall. That’s not a technicality; it’s the difference between a documented, insurable opening and one that puts your home and your policy at risk. Our team knows the exact NOA requirements, the permitting steps, and the inspection sequence Miami-Dade demands. No generic window guide covers this. We do.
Here’s what a compliant quote includes that a cheap one leaves out: the NOA and Florida Product Approval numbers for every unit, pulled and matched to each opening’s design pressure requirements, the permit application with Miami-Dade, and the final wind mitigation inspection documentation your insurance carrier needs. If a quote doesn’t mention these, the quote isn’t for a compliant Miami job.
In a 1962 concrete block ranch in West Miami, our crew removed original single-pane aluminum sliders and installed PGT impact-rated casement windows with laminated glass interlayers. Each unit’s Miami-Dade NOA and Florida Product Approval were pulled for the permit package, and the homeowner’s wind mitigation inspection afterward documented every opening as large-missile rated for their insurance discount. That’s what a proper Miami window replacement looks like, from first measure to final inspection.
