AfterFast, Reliable Impact Windows Across Miami
Window Replacement - Miami isn’t a cosmetic upgrade. It’s the thing that keeps your house standing when a Cat 4 spins off the Atlantic and the insurance adjuster asks what you did to harden the opening. Most Miami homes built before Andrew still carry original jalousie windows, and every single one of those aluminum louver jobs fails current wind-load code. We replace them with Miami-Dade NOA impact units, we do it at a fixed written price, and we answer the phone when you call (850) 930-1813. The work is coordinated from our Miami office, and our crews live here, in Coral Gables, in Hialeah, in Westchester. We know what the salt does to frames on SW 8th Street. We know what the insurance carrier wants to see on the wind mitigation report.
Why Winslow Windows & Doors Is Miami’s Preferred Impact Windows Company
Ed Winslow started this company in 2011, and he put his name on it because his word is the warranty. We’re the locally owned operation that replaced the faceless national chain, and our Miami customers talk to us the way you’d talk to a neighbor who happens to be a window guy. We run background-checked, uniformed technicians on every job, we publish our address and license number, and our Impact Windows team has handled more jalousie-to-impact conversions in pre-1980 CBS homes than most estimators will see in a career. That matters because the older Miami housing stock has specific rough-opening quirks that out-of-town bids consistently miss.
Our customers across Miami consistently cite two things: the price on the written estimate is the price on the final invoice, and when they called about the install, a live person picked up. Not a callback queue. Not a call center in another state. Someone who knows that a unit going into a Hialeah CBS home needs custom buck framing. Ed’s name is on the door, and on every job we do.
Our Impact Windows Services in Miami
Impact Window Replacement & Installation
We install Door Installation in Miami and impact windows rated for the Miami-Dade High Velocity Hurricane Zone (HVHZ). That means every unit carries a Notice of Acceptance (NOA) specific to the configuration, with design pressures matched to the opening, never a generic rating above +/-100. We handle the demo, the framing correction, the installation, and the documentation your carrier needs for wind mitigation credits. For most Miami homes the replacement runs $800 to $1,500 per window installed, and the work is done by a trained professional who knows the difference between a Miami-Dade NOA and a generic Florida Product Approval when the inspector asks.
Jalousie-to-Impact Conversions
If you own a 1950s-to-1980s CBS home in West Little Havana, Westchester, or Miami Shores, you’ve probably got jalousie windows sized to a rough-opening standard that no longer exists. Modern NOA impact units don’t fit those openings without custom buck framing. We build that bridge with pressure-treated lumber, seal the jamb-to-buck gap with marine-grade polyurethane, and install laminated impact glass that meets large-missile ratings. This isn’t an add-on line item we spring on you after demo. It’s in the estimate from day one because our estimators know the housing stock.
Wind Mitigation Inspection Prep
Florida carriers want to see documented opening protection before they’ll write or renew a policy in Miami. We don’t just install the windows, we prepare the paperwork: NOA numbers per configuration, product approval documents, and a tidy record your wind mitigation inspector can verify in one pass. No fumbling, no missing forms, no second inspection because the carrier rejected the first one. The inspection itself typically runs $75 to $150, and the premium credit that follows can average around 25% on the windstorm portion.
Salt-Air Resistant Hardware Upgrades
Miami’s salt-laden air off Biscayne Bay corrodes standard aluminum hardware fast. Jamb screws seize. Sash balances bind. Three to five years in, the window that looked fine at install is sticking and grinding. For coastal-adjacent homes we specify stainless or hot-dip hardware and marine-grade finishes on frame components. The upgrade costs more up front, but it buys you an extra decade before the salt wins. We’d rather install it right the first time than sell you a cheaper inland-spec that rots from the inside.

Trusted Brands We Service in Miami
We’re an authorized installer for the brands that actually hold up in Miami’s wind and salt profile: PGT, CGI, CWS, ES Windows, ECO Window Systems, Miami Mr Glass service, Therma-Tru. For this market, we lean on ECO Window Systems for custom jalousie-to-impact conversions where the rough opening needs a non-standard size, Mr-Glass for retrofit configurations, and Therma-Tru for impact-rated entry doors that match the front elevation on a Coral Gables Mediterranean or a Hialeah ranch. Because we’re local, we stock commonly needed components in Miami, which means faster turnaround when a unit needs re-glazing or hardware replacement down the line. Big-box stores hand you a ticket number. We hand you Ed’s word.
Common Impact Windows Problems We See in Miami Homes
- Salt-air corrosion on non-HVHZ-rated aluminum frames. Homeowners who bought inland-spec replacements five years ago now have jamb screws that won’t turn and sashes that bind mid-travel. The salt off Biscayne Bay and the Atlantic corrodes uncoated aluminum faster than any inland market in the state.
- Shattered single-pane “hurricane glass” without a Miami-Dade NOA. We’ve walked into homes after a Cat 2 where the owner believed they had impact protection. The interlayer was absent, the pane blew out, and the opening was breached. If the unit doesn’t carry a Miami-Dade NOA, it’s not impact protection in this wind zone.
- Wind-driven rain blowing through the jamb-to-buck gap. Original jalousie rough openings not sealed with closed-cell backer rod leave a percussive failure path: wind pushes water through the pocket between the buck frame and the CBS wall, and the drywall delaminates at the jamb. We see this in Hialeah and Westchester all the time.
- Out-of-town bids missing the buck-framing cost. Older Miami CBS homes need custom rough-opening correction for every NOA replacement. Estimators who don’t know the housing stock underbid the labor, then either eat the job or hit the homeowner with a change order. A local crew with jalousie-specific experience prices it accurately from the first estimate.
Pricing for Impact Windows in Miami, FL
Impact window pricing in Miami runs from about $800 to $1,500 per window installed, with single-hung units landing between $900 and $1,800, and large or custom openings at $2,500 to $5,000 and up. Whole-home packages for a typical three-bedroom CBS home run $8,000 to $25,000 depending on opening count, floor height, and whether you’re converting from jalousies. The biggest variable in Miami specifically is the obsolete rough-opening size on pre-1980 homes: if your jalousies are sized to a standard that no longer exists, every opening needs custom buck framing, and that adds labor most national estimators don’t include. The second variable is salt-air upgrades: stainless hardware, marine-grade frame finishes, and sealed jamb-to-buck gaps cost more up front and fail much later. We give you a fixed written quote after a free in-home measure, and that number doesn’t move unless you change the scope. Call (850) 930-1813 to schedule yours.
What Impact Windows Cost in Miami
Here’s the honest breakdown. A standard impact window in Miami runs $800 to $1,500 installed. Impact single-hungs range from $900 to $1,800. Large or custom openings, picture windows, and Sliding Glass & Patio Doors in Miami run $2,500 to $5,000 or more. A whole-home package for a typical Miami CBS home lands between $8,000 and $25,000 plus. What drives the cost here is the opening count, the wind zone (all of Miami-Dade is HVHZ), floor height, and whether the existing rough openings were built for jalousies. If they were, every single opening needs buck framing, and that’s a labor cost the cheap quote doesn’t show. We write the real number on the estimate the first time, and it’s the same number on the invoice when the job is done. The ask is a free in-home measure and written quote. Call (850) 930-1813.
On a West Little Havana CBS home, our techs removed a wall of original jalousie windows and found the rough openings 1-1/2 inch narrower than any modern Miami-Dade NOA unit from CGI, Mr-Glass, or even custom-order ECO Window Systems. We bucked every opening with pressure-treated lumber, sealed the jamb-to-buck gap with marine-grade polyurethane, and installed double-hung laminated glass units with a 50 psf design pressure rating. The homeowner closed out their first wind mitigation inspection with a $1,100 annual premium credit. That’s the difference between a local crew that knows the housing stock and a national installer flying blind.
Florida Pays You Back
The incentives stack if you know what to claim. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, though program windows open and close based on state funding. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit returns 30% of the product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection ($75 to $150), Florida carriers typically apply a windstorm-premium credit averaging around 25% on the windstorm portion. We don’t guarantee program approval or carrier numbers, since both are set elsewhere, but we do provide the documentation that makes the claim clean and straightforward.
One comparison worth making: impact windows versus hurricane shutters. Shutters work, but you have to be home to hang the panels, store them somewhere, and fight the wind while you’re doing it. Impact windows are permanent protection, no panels, no pre-storm scramble, and they perform all year as the security and energy-glazing layer. For Miami homeowners who travel during storm season, impact windows are the difference between a protected house and an open envelope.

FAQs - Impact Windows in Miami
You can’t, because jalousie frames are structurally incapable of carrying Miami-Dade NOA impact glazing. The louver channels, the thin aluminum frame walls, and the crank mechanism were never designed to hold a laminated large-missile-rated unit under sustained Category 4 or 5 wind loads. Retrofitting impact glass into a jalousie frame would leave the opening non-compliant and your insurance carrier would reject the wind mitigation credit. The correct fix is full replacement with an NOA-rated impact window sized to the existing rough opening, which in pre-1980 CBS homes almost always means custom buck framing. Call (850) 930-1813 for an exact quote on your home.
In Miami-Dade County, no. Because Miami sits entirely within the High Velocity Hurricane Zone, which it shares only with Broward, carriers writing policies in Miami require products carrying a Miami-Dade Notice of Acceptance. A Florida Product Approval alone doesn’t meet the HVHZ standard, and the wind mitigation inspection will flag it. We install Miami-Dade NOA products as a matter of course, and we provide the NOA documentation with every job. If you’re unsure about what your carrier needs, the free estimate is the place to start.
Expect to pay roughly 10% to 20% more for salt-air-resistant upgrades: stainless or hot-dip hardware, marine-grade frame finishes, and sealed jamb-to-buck gaps with closed-cell backer rod. That might mean a few hundred dollars more per opening. The inland-spec unit will work initially, but in Miami’s salt-laden air, uncoated aluminum frames start corroding within three to five years, jamb screws seize, and sash balances bind. The cheap spec costs more within a decade because you’ll replace it. We’d rather quote the marine-spec version honestly and install it once. Estimates are free – call (850) 930-1813.
Almost never. The original buck framing on Miami’s 1950s-to-1980s CBS homes was built to a rough-opening standard that no longer exists, and the lumber is typically degraded from decades of Miami heat, humidity, and wind-driven rain. Reusing it would compromise the structural connection between the NOA impact unit and the CBS wall, which fails the wind-load requirement and voids the manufacturer’s coverage. We replace the buck frame with pressure-treated lumber, seal the gap with marine-grade polyurethane, and document the correction. Call (850) 930-1813 for a fixed written quote on your conversion.
You need the Miami-Dade NOA number for each installed configuration, the product approval documentation, the permit record, and a completed wind mitigation inspection form from a licensed inspector. The inspector verifies that each opening carries approved impact protection, records the design pressure ratings, and submits the results to your carrier. We prepare all of the documentation for you at install, so the inspector has what they need on the first pass. The inspection typically costs $75 to $150, and the windstorm-premium credit that follows averages around 25% on the windstorm portion. If you want to get ahead of the paperwork before you buy, call (850) 930-1813.
