AfterFast, Reliable Window Installation Across Miami
Window installation in Miami means something different than it does 30 miles north. In Miami-Dade County, every window you put in has to carry its own Notice of Acceptance number, a county-level certification stricter than the Florida Building Code. We’re Winslow Windows & Doors, and we’ve been navigating Miami-Dade’s NOA system long enough to know exactly which units pass inspection the first time. Call (727) 860-0593 and you’ll get a live person, not a voicemail loop. Ed Winslow’s name is on the door, and on every job we do in Miami.
Why Winslow Windows & Doors Is Miami’s Preferred Window Installation Company
Miami homeowners have watched plenty of out-of-town crews chase post-storm work with products that pass Florida statewide approval but fail Miami-Dade’s building department cross-check. That mistake means an automatic rejection, a re-order, and weeks of delay. We don’t make that mistake because we’ve pulled permits in Miami-Dade long enough to know the NOA database like the back of our hand. Since 2011, we’ve built our reputation as a locally owned, owner-operated company with a published address and license number. No shell companies. No ticket numbers. Just Ed Winslow and a crew that shows up in uniform, background-checked, and ready to anchor windows into the concrete block construction that defines Miami’s housing stock.
Miami customers don’t need vague promises. They need a company that knows what happens when salt-laden air from Biscayne Bay meets aluminum frames, and what the county inspector will look for before sign-off. We know both. The Done Right Promise backs every installation: if it’s not done right, we make it right. Period. That’s a lasting standard no national chain can match.
Our Window Installation Services in Miami
Single & Double Hung Windows
In Miami’s 1950s-1970s concrete block homes across Hialeah and Westchester, single and double hung windows are the most common replacement pick. You get a traditional look with modern impact-rated glass that holds up to Miami-Dade’s wind zone requirements. We anchor into masonry, not wood framing, and use corrosion-resistant hardware that won’t seize up in the salt air.
3-Panel Sliding (3-Lite Roller) Windows
Three-panel sliders open up Miami’s view corridors in ways standard windows can’t, and they’re a favorite in Coral Gables and along the bay side. In a home with original jalousie windows, a 3-lite roller transforms airflow and natural light while meeting Miami-Dade NOA impact standards. Expect custom fabrication to run 4-6 weeks before installation.
Casement Windows
Casement windows crank outward and seal tight, which matters in a city where humidity averages above 75% most months. In Miami’s older CBS construction, casements give you better water resistance at the jamb than sliding tracks ever will. We match each unit to the specific design pressure of its opening, so you’re not over- or under-specced.
Horizontal Roller Windows
Horizontal roller windows are common in Miami’s mid-century homes, but many originals have frames corroded from decades of coastal air. We replace them with new units that carry Miami-Dade NOA certification and feature modern, non-corrosive hardware. This is one of the most common full-replacement jobs we do from Hialeah to Little Havana.

What Window Installation Costs in Miami
Here’s what Miami pricing actually looks like. A typical impact window runs $800-$1,500 per unit installed. Impact single-hung windows land around $900-$1,800 depending on size and wind zone. Large or custom openings, like a picture window or a 3-lite slider, run $2,500-$5,000. Whole-home packages across a Miami residence generally start around $8,000 and climb toward $25,000 or more for larger properties with multiple openings. What moves the number: opening count, wind zone, floor height, and whether your home is concrete block or a rare wood-frame build. We’ll walk your home, measure each opening, and give you a written, line-item quote with no trip charge inside Miami-Dade. Call (727) 860-0593 to schedule your free in-home estimate.
Common Window Installation Problems We See in Miami Homes
- Crumbling 60-year-old masonry: Anchoring new windows into deteriorated concrete block without repair causes frame movement and water intrusion at the jamb. We assess the substrate before we ever order a unit.
- Wrong product approval: A contractor installs a window with Florida statewide approval but no Miami-Dade NOA number. The county rejects it at inspection, and the homeowner waits on a full re-order.
- Flashing built for wood framing: Miami’s CBS homes need pan-flashing and sealants compatible with concrete substrate. The wrong detail leads to mold at the sills within a season. We see it constantly.
- Original jalousie windows: Those louvered panels give almost zero wind or water resistance. In a hurricane zone, they’re a liability, but replacing them properly requires reframing the opening, not just swapping glass.
On a 1962 CBS home in Westchester, we opened the wall around an original jalousie window and found undersized wood bucks with active dry rot from years of condensation. The county cross-check would have rejected any standard permit. Our crew reframed the opening with pressure-treated lumber, flashed the concrete substrate with a compatible membrane, and installed PGT impact-rated double-hungs carrying Miami-Dade NOA numbers. Then we documented the wind mitigation credits for their insurer.
Trusted Brands We Service in Miami
We install from a lineup we know will pass Miami-Dade inspection on the first attempt: CWS, ES Windows, and Mr-Glass among them. These are authorized brands, not whatever happened to be on a warehouse shelf. In Miami, product selection isn’t a style decision alone; it’s a compliance decision. The county’s building department cross-checks every window and door against its online NOA database before sign-off. We stock local parts for Miami customers and turn around service calls fast. Our Window Installation team knows which NOA numbers match your openings before we ever place the order.
Florida Pays You Back
Florida’s incentive stack is real, and Miami homeowners should know what’s on the table. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact windows. Florida also exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit returns 30% of product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection (typically $75-$150), many Miami homeowners see their windstorm premium drop by roughly 25% on the windstorm portion. We don’t guarantee those numbers; your carrier sets the final rate. But we’ll document everything your insurer needs.
One comparison worth making: impact windows beat hurricane shutters for most Miami homeowners because you get permanent protection with no panels to haul out before a storm. No storage racks in the garage, no last-minute scramble when a watch gets issued. The windows do the job every single day, storm or no storm.

The NOA Reality Most Window Pages Skip
Miami-Dade County requires every window installed here to carry its own Notice of Acceptance (NOA) number. That’s a stricter product-approval system than the Florida Building Code used in neighboring Broward and Palm Beach counties. It was born from Hurricane Andrew’s 1992 devastation, and it means impact-rated glass and reinforced framing aren’t an upsell in Miami. They are the legal minimum for virtually every replacement job in the county. Contractors pulling permits in unincorporated Miami-Dade learn quickly that the building department cross-checks every product against the online NOA database before inspection sign-off. Showing up with a product that passed Florida statewide approval but lacks its own Miami-Dade NOA number means automatic rejection and a re-order. That’s the costly mistake that separates locals from out-of-town crews. We vet every unit before we order it, because a rejected inspection doesn’t just delay the job; it leaves your home open to the elements while we sort out the paperwork.
How We Handle What’s Behind the Wall
Opening up an older Miami home for a window replacement usually turns up more than anyone expected. Outdated wiring run too close to rough openings. Undersized or rotted wood bucks. Failed waterproofing that never showed itself until we pulled the old frame. And the code upgrades a permit triggers once the walls are open. This is the single biggest reason a remodel quote moves.
Here’s our process: we inspect first, before you’re committed to anything. If we believe the opening needs reframing or waterproofing work, we write an allowance into the contract so you know the ceiling. When we find something behind the wall, we price it and get your written approval before we touch it. No change orders you didn’t sign off on. No surprise invoice at the end. In Miami’s CBS construction, that often means repairing deteriorated concrete around the opening, replacing wood bucks with pressure-treated lumber, and flashing for a masonry substrate rather than wood framing.

FAQs - Window Installation in Miami
Miami-Dade created its own Notice of Acceptance system after Hurricane Andrew in 1992 because the statewide Florida Building Code wasn’t strict enough for the county’s wind zone. Every window product installed in Miami-Dade must carry its own NOA number, specific to that product configuration. The county’s building department verifies each NOA against its online database before inspection sign-off. Installing a window with only Florida statewide approval means automatic rejection and a re-order. We check NOA numbers before we order, so our Miami customers don’t live through that delay. Call (727) 860-0593 if you’re unsure whether your current windows carry NOA certification.
Yes, in most Miami homes the difference is noticeable. Impact windows with low-E coatings cut solar heat gain, and tight seals reduce the humidity infiltration that makes your AC work harder. Miami’s average humidity above 75% means your system fights moisture, not just temperature. Properly installed impact windows reduce both. The federal 25C energy credit can return 30% of product cost, up to $600 per year, on qualifying units. We’ll document your units for that credit as part of the install.
Absolutely. Jalousie windows are the defining South Florida relic, and they provide almost zero wind or water resistance. Replacing them isn’t a simple glass swap, though. The old louvered units mount differently than modern impact windows, so the opening typically needs reframing with pressure-treated lumber, new flashing, and sometimes masonry repair around the rough opening. In a 1958 concrete block home, we anchor into the block with the right fasteners and sealants for that substrate. The result is a modern impact window with a Miami-Dade NOA number, and a home that’s dramatically quieter and cooler. Call (727) 860-0593 for a free in-home measure and written quote.
We inspect first and write allowances into the contract for the likely repairs before work begins. When we find something unexpected, we stop, document it, price it, and get your written approval before we proceed. You will never receive a change order you didn’t sign. In Miami’s older CBS homes, common findings include undersized wood bucks with dry rot from years of condensation, corroded anchors, or wiring that needs to be moved to meet current code. Each gets handled the same way: told, priced, approved, then done. That’s Ed Winslow’s standard on every job in Miami.
In most cases, yes. After a wind-mitigation inspection (typically $75-$150), many Miami homeowners see their windstorm premium drop by roughly 25% on the windstorm portion. Your carrier sets the final number, not us. We document every window’s NOA number, design pressure rating, and installation photo for your insurer. We also recommend pairing the window install with a roof mitigation inspection if your roof is older, since carriers look at both. Call (727) 860-0593 and we’ll talk through what your home needs.
