AfterFast, Reliable Impact Windows Across Miami
Impact windows in Miami are not optional. Miami-Dade County is the only jurisdiction in the nation where every window and door must carry a Miami-Dade Notice of Acceptance (NOA), a product-certification standard stricter than anything else in Florida or the US. That means when you replace windows here, you’re dealing with a code-compliance requirement first and a storm-hardening upgrade second. Winslow Windows & Doors has installed impact-rated units throughout Miami for over a decade, and Ed Winslow’s name is on every job. Call (863) 862-5435 to schedule a free in-home measure and written quote.
Why Winslow Windows & Doors Is Miami’s Preferred Impact Windows Company
Miami homeowners have a specific set of problems that contractors from Orlando or Tampa simply never see. Jalousie windows in pre-1992 Hialeah and West Miami homes fail HVHZ inspection instantly. Salt-air corrosion eats standard aluminum frames within a mile of Biscayne Bay. Older CBS homes hide undersized or rotted wood bucks behind original window trim. We know this because we’ve pulled thousands of those windows out of Miami walls.
Ed Winslow founded this company in 2011 and still runs it personally. That’s not a marketing line. His phone number is published, his license number is published, and when something goes wrong on a job, the homeowner talks to Ed, not a call center supervisor in another state. Homeowners across Coral Gables, Brickell, Kendall, and Hialeah have trusted us with their impact window projects because we write allowances into the contract before demolition, price every surprise in writing before we touch an opening, and stand behind the finished install with the 36500-Day Done Right Promise.
Every technician who shows up at a Miami home is background-checked and uniformed. A live person answers our phone 24 hours a day, seven days a week. No voicemail loops. No ticket numbers. Just a neighbor you can call at 2 a.m. and someone will actually answer.
Our Impact Windows Services in Miami
Impact Window Installation
Full replacement of existing windows with NOA-certified impact units rated for Miami-Dade’s High-Velocity Hurricane Zone (HVHZ). We handle single-hung, casement, horizontal roller, and picture windows in vinyl, aluminum, and marine-grade frames. Installation is often completed in as fast as a single day once your units arrive. Custom fabrication typically runs 4 to 6 weeks.
Jalousie Window Replacement
Jalousie windows, those louvered glass blades still common in pre-1992 homes across Hialeah and West Miami, are entirely prohibited under HVHZ code. They provide zero impact resistance and windstorm insurers non-renew policies until they’re replaced. We specialize in converting jalousie openings to properly framed, sealed, and rated impact units, including the structural reframing that older CBS walls almost always require once you pull the originals.
Impact Door and Sliding Glass Door Installation
Window openings get more attention, but doors are usually the first point of wind-driven rain failure in a Miami home. We install impact-rated entry doors, French doors, and sliding glass patio doors that meet the same Miami-Dade NOA and design-pressure requirements as your windows. In high-rise condos along Brickell and Edgewater, we coordinate with HOA architectural review boards to match existing aesthetic standards.
Window Repair and Hardware Replacement
Miami’s coastal salt air corrodes standard rollers, balances, and locking hardware faster than almost anywhere in the country. If your impact windows are seizing, leaking, or refusing to lock, we repair them. We stock common replacement hardware for PGT, CGI, and ES Windows product lines, which keeps turnaround faster for Miami customers who don’t want to wait on a backordered part.

Trusted Brands We Service in Miami
Winslow Windows & Doors is an authorized installer for eight premium brands, and we stock seals, rollers, and lock assemblies for the lines most common in South Florida. For Miami clients, we typically specify CGI for coastal high-rise applications, PGT for single-family CBS homes, and ES Windows or ECO Window Systems where design pressure demands are high and sightlines matter. CWS units work well for contemporary floor plans with large glazing areas. Every product we install carries a Miami-Dade NOA with design pressure ratings matched to the specific opening, never above +/-100 PSF.
Common Impact Windows Problems We See in Miami Homes
- Jalousie windows in pre-1992 homes. Any home built before Hurricane Andrew in Hialeah, West Miami, or unincorporated Miami-Dade likely has at least a few jalousie units. They fail HVHZ inspection instantly and trigger non-renewal notices from windstorm carriers.
- Salt-air corrosion on standard aluminum frames. Homes within a mile of Biscayne Bay or the Atlantic eat ordinary aluminum at an alarming rate. Non-marine-grade frames seize shut or start leaking within a few seasons, long before their useful life should end.
- Rotted or undersized wood bucks behind original windows. Opening up a 1950s or 1960s CBS wall often reveals framing that was never built for a modern impact-rated unit. Slapping a new window onto a failed buck leaks and loses its design pressure rating.
- Wind-driven rain failures around aging thresholds. Miami’s near-daily summer thunderstorms push water sideways. Old door thresholds and window seals that never leaked before suddenly fail once they’re asked to keep hurricane-driven rain out.
Pricing for Impact Windows in Miami, FL
Impact window pricing in Miami runs higher than inland markets, and there’s a reason. Every unit installed here must carry a Miami-Dade NOA, which eliminates budget-grade products sold in Orlando or Tampa and forces the entire conversation toward properly certified, marine-grade construction. A standard impact window in Miami runs $800 to $1,500 per window installed. Single-hung units run $900 to $1,800. Large custom openings run $2,500 to $5,000. Whole-home packages typically start around $8,000 and can exceed $25,000 for larger homes with multiple sliding doors and custom shapes.
What moves the price here: the number of openings, the wind zone your home sits in, floor height, frame material, and whether the existing rough opening needs structural reframing once we pull the original window. We measure in person, write every allowance into the contract before demo starts, and price any surprise in writing before we touch an opening. Call (863) 862-5435 to schedule a free in-home measure and written line-item quote.
What Impact Windows Costs in Miami
Let’s talk about the real anchors. Impact windows generally run $800 to $1,500 per window installed in Miami. Impact single-hung units run $900 to $1,800. Large or custom openings (picture windows, oversized sliders, geometric shapes) run $2,500 to $5,000. A whole-home package across a typical 3-bedroom CBS ranch runs $8,000 to $25,000+ depending on opening count and frame selection.
If you’re comparing quotes, ask each contractor these three things: Is the unit NOA-certified for Miami-Dade County? Is the design pressure rating matched to the specific opening, never above +/-100 PSF? Does the quote include reframing allowances for what we’ll likely find inside the wall? If a quote can’t answer all three in writing, keep shopping. Our quotes always do.
Call (863) 862-5435 for a free in-home measure. We’ll walk your windows, show you what we’re seeing, and hand you a written number before we leave.
Florida Pays You Back
Here’s what Miami homeowners should know before writing the check. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida also exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit can return 30% of product cost, up to $600 per year, for qualifying units. And once your home passes a wind-mitigation inspection (which runs $75 to $150), windstorm carriers typically credit around 25% off the windstorm portion of your premium, which in Miami can be the largest single line on the policy. Programs and carriers set the final numbers, so we’ll help you document everything but we won’t promise a dollar figure a carrier hasn’t committed to.

FAQs - Impact Windows in Miami
A Miami-Dade Notice of Acceptance (NOA) is a product-certification standard that verifies a window or door has been tested and approved for use in the High-Velocity Hurricane Zone (HVHZ). Miami-Dade County is the only jurisdiction in the nation that requires it. A window without an NOA cannot legally be installed in Miami, period. If a contractor offers to install a unit that doesn’t carry an NOA, walk away. Call (863) 862-5435 and we’ll show you the NOA paperwork before we order anything.
No. Jalousie windows are entirely prohibited under HVHZ code and cannot be brought into compliance with storm panels or any other add-on. Windstorm insurers non-renew policies until they’re replaced. The only fix is full removal and replacement with NOA-certified impact units, which often requires reframing the opening. We handle that reframing daily in Hialeah and West Miami homes.
Windstorm carriers in Florida require the entire building envelope to meet HVHZ standards, not just a few openings. If you replaced three windows and left two jalousies and an old aluminum slider, your insurer sees a non-compliant structure and non-renews. A wind-mitigation inspection after partial work reads as incomplete, not improved. We always recommend budgeting for a full opening-by-opening assessment before starting a partial replacement. Call (863) 862-5435 for a free assessment and written plan.
Concrete block homes from the 1950s through the 1980s were rarely framed with modern impact units in mind. When we pull the original window, we often find undersized or rotted wood bucks, corroded aluminum jambs, and block pockets that have been soaking up wind-driven rain for decades. That means the scope, and the price, moves once the wall is open. We write allowances into the contract before demolition and price every change order in writing before we touch an opening. No one opens your wall and hands you a surprise invoice. Call (863) 862-5435 for a free estimate.
Yes, and the effect is measurable. Impact windows use laminated glass with a low-E coating that blocks a significant portion of solar heat gain, which is a major driver of cooling load in Miami’s year-round heat and humidity. The federal 25C energy credit recognizes this with a 30% credit on qualifying units, up to $600 per year. Your windstorm premium credit, which averages around 25% off the windstorm portion, usually saves more than the cooling reduction. Call (863) 862-5435 for exact numbers on your home.
