AfterFast, Reliable Window Replacement Across Miami
Replacing windows in Miami isn’t like replacing windows anywhere else. Between the salt air off Biscayne Bay, the humidity that never quits, and Miami-Dade County’s NOA product-approval rules, a window job here demands local knowledge you won’t get from an out-of-town crew or a big-box installer. Winslow Windows & Doors has been doing this work since 2011, and Ed Winslow’s name goes on every job we finish. If you’re wondering whether your windows meet code, whether your frames are corroding from the inside, or what a replacement actually costs in your neighborhood, call us at (727) 860-0593. A live person answers, day or night.
Why Winslow Windows & Doors Is Miami’s Preferred Window Replacement Company
We’re locally owned and owner-operated, not a franchise with a rotating cast of subcontractors. Every tech who shows up at your door in Miami is background-checked and in uniform, so you know who’s on your property before the truck parks. Our published address and license number are on every estimate. No shell companies, no mystery crews.
Miami homeowners deal with a specific set of problems: failed seals from humidity, seized sashes from galvanic corrosion, and windows that never had a Miami-Dade NOA number to begin with. We’ve replaced original jalousie windows in Hialeah, retrofitted impact glass in Coral Gables, and full-framed 1970s CBS homes in Westchester. That’s not a list of places we “serve” on a website. Those are blocks we’ve worked on.
Ed Winslow founded this company in 2011 and still runs it. When a Miami customer calls about a warranty question or a concern after install, the answer comes from someone with skin in the game, not a call-center script. The Done Right Promise says it plainly: if it’s not done right, we make it right. That’s a lasting standard. No national chain offers it because no national chain would survive it.
Our Window Replacement Services in Miami
Full Frame Replacement
Most Miami homes built between the 1950s and 1970s are concrete block and stucco. That changes everything about how a window goes in. You can’t just screw into wood framing like you would on a frame house in the Northeast; you anchor into masonry, and you flash it for a concrete substrate. A full frame replacement in Miami means pulling the old window down to the rough opening, repairing any spalling or water damage in the block, and setting the new unit with compatible sealants. We do this on CBS homes across Window Replacement in Miami every week.
Insert Window Replacement
If your existing frames are still square and solid, an insert replacement can save you money and time. The new window slides into the old frame, so we don’t disturb stucco or interior trim. But here’s the Miami catch: aluminum frames near Biscayne Bay often look fine on the outside while corroding from the inside. Before we quote an insert, we check the frame for hidden galvanic damage. Recommending an insert on a frame that’s about to fail would be a shortcut. We don’t do shortcuts.
Vinyl Replacement Windows
Vinyl makes sense in Miami for one big reason: it doesn’t corrode. Salt-laden air eats aluminum; vinyl shrugs it off. We install vinyl replacement windows with stainless steel hardware and multi-point locking systems that hold up in a coastal environment. For homeowners in Miami Beach and along the bay, vinyl impact-rated units with Miami-Dade NOA certification give you corrosion resistance and code compliance in one product.
Energy-Efficient Upgrade
Miami’s average humidity sits above 75% almost year-round. That drives condensation at window sills and along the glass edge, which leads to mold, peeling paint, and warped trim. Low-E glass and thermal breaks aren’t luxury add-ons here; they’re how you keep an air-conditioned house from sweating through its windows in August. We install energy-efficient units from brands like ES Windows and ECO Window Systems, both of which carry configurations rated for Miami’s climate and wind zone. The federal 25C energy credit applies to qualifying units, which helps offset the cost.

Trusted Brands We Service in Miami
We’re an authorized installer for PGT, Therma-Tru, ES Windows, and ECO Window Systems, among others. Why does that matter for a Miami homeowner? Because authorized means we stock local service parts, we know the product lines cold, and when a window needs a replacement sash or hardware under warranty, we’re not waiting on a third-party distributor three states away. Fast turnaround on parts means less downtime for your home. Whether you’re replacing a single failed unit or a whole wall of jalousies, we’ll match the right brand to your opening, your wind zone, and your budget.
Common Window Replacement Problems We See in Miami Homes
- Seized sashes from galvanic corrosion. Salt air from Biscayne Bay and the Atlantic creates a galvanic reaction between dissimilar metals in window hardware. Aluminum frames with steel screws become batteries, and within a decade the sash won’t move. We specify stainless steel hardware and corrosion-resistant components on every coastal replacement.
- Failed seals and fogged glass. Miami’s humidity finds every weak seal. Once the insulating gas escapes a double-pane unit, you get fog between the panes and a window that no longer insulates. This is rarely a repair; it’s a replacement call.
- Windows without Miami-Dade NOA numbers. If your home still has original single-pane jalousie windows, or if a previous owner installed units with Florida statewide approval but no Miami-Dade NOA, your house may fail inspection on a resale or after a claim. This is the single most common problem we see in Hialeah, Little Havana, and Westchester.
- Condensation and mold at sills. Poor pan-flashing on masonry openings lets water wick into the block. High humidity keeps it wet. By the time you see mold on the drywall, water has been migrating for months. Proper flashing and weep-hole maintenance fix this at the source.
Pricing for Window Replacement in Miami, FL
What moves the price in Miami specifically: the wind zone and design pressure rating required for your address, whether the opening sits on an upper floor (which drives up install labor), the substrate condition behind the old frame, and whether the product you want carries a Miami-Dade NOA number. Cheaper products without NOA approval won’t pass inspection. Period. Call (727) 860-0593 for a free in-home measure and written quote. Upfront pricing, no change orders.
What Window Replacement Costs in Miami
Let’s put those numbers in context. Impact windows in Miami generally run $800 to $1,500 per window installed. Impact single-hung falls between $900 and $1,800. Large or custom openings, like a full-height fixed window or a specialized geometric shape, hit $2,500 to $5,000. Whole-home packages on a typical 1950s to 1970s CBS house land anywhere from $8,000 to $25,000-plus, depending on how many openings and how many are full frame versus insert.
The gap between a coastal-spec window and an inland-spec version of the same opening is real, and it’s worth being honest about it. A builder-grade aluminum window with steel hardware and no NOA number might save you $150 to $300 per opening today. But near Biscayne Bay, that hardware starts corroding within five years, the seals fail, the sash seizes, and in a decade you’re paying to replace it again. The cheap spec costs more within a decade. We’d rather install it once with marine-grade hardware, sealed joints, and a real NOA number. That’s the difference between a price and a cost.
One more thing to keep straight: a big-box store will sell you an impact window, but they won’t pull a Miami-Dade permit for you, and their installers may not know an NOA from a UPC code. A licensed impact specialist runs the NOA cross-check before you ever put a deposit down, because showing up at final inspection with the wrong product means an automatic rejection and a re-order. That mistake usually costs more than the “savings” from the big-box price. The free in-home measure and written quote from us costs nothing. Call (727) 860-0593 and compare line by line.
Florida Pays You Back
The incentives on the table right now make replaced windows a different financial equation than they were ten years ago. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and a wind-mitigation inspection ($75 to $150) is the first step. Florida also exempts impact-resistant windows and doors from sales tax, which takes a meaningful bite out of the invoice. On the federal side, the 25C energy credit returns 30% of product cost on qualifying units, up to $600 per year. And after a wind-mitigation inspection, most Miami homeowners see a credit on the windstorm portion of their insurance premium, averaging around 25%.
No guarantees here. Programs change, carriers set their own numbers. But we’ll walk you through what applies to your home and your policy, line by line, before you sign anything. That’s the way Ed runs the company: full transparency, no pressure.

FAQs - Window Replacement in Miami
Miami-Dade County enforces its own product-approval system called Notice of Acceptance, or NOA, and it is stricter than the Florida Building Code used by neighboring Broward and Palm Beach counties. Any window installed in Miami-Dade must carry its own NOA number, a requirement born from Hurricane Andrew’s 1992 destruction. If a product has statewide Florida Product Approval but no Miami-Dade NOA, the county’s building department cross-checks it against the online NOA database and rejects it at inspection. That means a re-order, more labor, and a blown schedule. Every window we install in Miami carries a valid Miami-Dade NOA for that specific configuration. Call (727) 860-0593 and we’ll verify your product choices before you commit.
Yes, and it’s one of the most common upgrades we do in Miami. Most jalousie windows are original to 1950s and 1960s CBS homes in neighborhoods like Little Havana, Hialeah, and Westchester. They provide almost zero wind or water resistance, and they don’t carry NOA certification of any kind. We replace them with impact-rated casement or single-hung windows that meet current code. We recently replaced a wall of original single-pane jalousies on a 1960s CBS home in Little Havana where the salt air had eaten through the aluminum frames. We installed PGT impact-rated casement windows with stainless steel hardware and masonry anchors, and the homeowner’s wind mitigation inspection passed the next week. That’s the typical before-and-after. Call (727) 860-0593 for a free in-home measure and exact quote.
HVHZ stands for High Velocity Hurricane Zone, and Miami-Dade County sits inside it. HVHZ-rated windows must pass more demanding testing for wind-borne debris impact and cyclic wind pressure than products rated only for the wind speeds used outside the HVHZ. Non-HVHZ impact windows may meet Florida Building Code elsewhere in the state, but they generally won’t satisfy Miami-Dade NOA requirements. We match the design pressure rating to the specific opening, never above +/-100, and we verify the NOA number for every configuration before order. Call (727) 860-0593 and we’ll explain what your address requires.
Often, yes, but the credit comes from the wind-mitigation inspection, not from the windows themselves. After installing impact-rated windows with Miami-Dade NOA certification, a wind-mitigation inspection ($75 to $150) documents the upgrade for your carrier. Most Miami homeowners see a credit averaging around 25% on the windstorm portion of their premium. The exact number is your carrier’s call. We’ll install to spec, and we’ll walk you through how to get the inspection scheduled and the paperwork filed. Call (727) 860-0593 for a free quote and a straight answer.
Salt-laden air from Biscayne Bay and the Atlantic creates a galvanic reaction between the aluminum frame and any non-stainless steel hardware. The two metals act like a battery in the presence of salt moisture, and the aluminum is what sacrifices itself. Within a decade, the sash seizes, the seals fail, and the frame starts to pit. We specify stainless steel or marine-grade hardware on every coastal replacement we do in Miami, and we use corrosion-resistant finishes wherever the window meets the stucco. If your frames are already pitted or seized, don’t force the sash; call (727) 860-0593 and we’ll assess whether you need a repair or a replacement.
