Fast, Reliable Window Replacement Across Westchester
Window replacement in Westchester means one thing before anything else: Miami-Dade NOA compliance. Every unit we install carries a current Notice of Acceptance on file with the county, because Westchester sits inside the High Velocity Hurricane Zone, the strictest wind-load jurisdiction in the country. If the product doesn’t have that NOA stamp, the inspector won’t pass it. Period.
Ed Winslow has been running Window Replacement crews across Miami-Dade since 2011, and we know exactly what Westchester’s 1950s and 1960s CBS ranch homes throw at us. Original jalousie windows, salt-pitted aluminum frames, humidity-bloated sashes that won’t seal. We replace them with impact-rated units built for this specific wind zone, and we schedule your free in-home measure at (850) 721-1218.
Why Winslow Windows & Doors Is Westchester’s Preferred Window Replacement Company
We’re the local crew that shows up knowing your house was likely built between 1955 and 1975, with concrete block walls, a flat or low-slope roof, and window openings sized for louvered jalousies nobody makes replacement parts for anymore. That’s not a guess. It’s what we see on nearly every street between Coral Way and Bird Road.
Westchester homeowners call us because Ed’s name is on the door, not a franchise number. Our techs are background-checked and uniformed, so you know who’s walking up your driveway before they knock. And when you call, a live person answers. 2 a.m., Sunday afternoon, doesn’t matter. No voicemail loop, no call center in another state.
We carry the Done Right Promise on every job. If it’s not done right, we make it right. That’s not a warranty card in a drawer somewhere. It’s Ed’s word, and Ed still answers the phone.
Our Window Replacement Services in Westchester
Full Frame Replacement
Most Westchester homes still have their original window frames, and after 50 to 70 years of salt air and humidity, those frames are done. We pull the entire assembly down to the rough opening, repair or replace any rotted or termite-damaged wood bucks, and set a new impact-rated frame with stainless fasteners rated for coastal exposure. Full frame replacement is the only way to fix a pitted, binding jalousie opening correctly. You can’t retrofit around a frame that’s already failing.

Insert Window Replacement
If your existing frames are still square and sound, an insert replacement keeps the frame and swaps the sashes and glass. It’s faster and less invasive, and it works well on Westchester’s CBS construction where the opening is set in concrete block. The catch: inserts still have to carry a Miami-Dade NOA for the final assembly, and the glazing label has to match the approved configuration. We verify that before we order anything.

Vinyl Replacement Windows
Vinyl frames handle Westchester’s humidity better than old aluminum ever did. They don’t pit, they don’t corrode, and they don’t sweat like single-pane aluminum in a 70% humidity July afternoon. We install vinyl impact units from authorized brands we trust, and every configuration is matched to the design pressure for your specific opening size and floor height. No generic “one size fits all” specs.

Energy-Efficient Upgrade
Westchester homes bleed cool air through original single-pane jalousies all summer long. Upgrading to low-E, double-pane impact glass cuts that loss dramatically, and you’ll feel it in the room the same week we install. The Florida sales-tax exemption on impact windows and the federal 25C energy credit both apply to qualifying units, which means the upgrade costs less than the sticker price before we even talk about your windstorm premium reduction.

Trusted Brands We Service in Westchester
We’re authorized installers for eight manufacturers, and on Westchester jobs we most often specify PGT, ECO Window Systems, and ES Windows because their HVHZ NOA catalogs cover the specific opening sizes and design pressures we see in postwar CBS ranch homes. Every unit comes with a transferable warranty covering accidental and hurricane glass breakage, delamination, and labor and materials. We order direct from the manufacturer, so there’s no middleman distributor markup, and your lead time matches the factory’s current production schedule.
Common Window Replacement Problems We See in Westchester Homes
- Salt-pitted aluminum jalousie frames. Westchester sits roughly 10 miles from Biscayne Bay, and the salt-laden air gets into the aluminum and pits it. Sashes bind, louver clips snap, and the windows stop sealing. We’ve pulled jalousies off Coral Way homes where the frames crumbled in our hands.
- Seal failure on original sliding glass doors. Non-impact sliders from the 1960s and 1970s lose their seals in Miami-Dade’s 70%+ humidity, and once the seal goes, water intrusion follows. By the time a wind-mitigation inspector fails the door, it’s been leaking for years.
- Permits pulled with the wrong product certification. We get calls from Westchester homeowners who hired an out-of-county crew, pulled a permit, and then failed inspection because the windows only had Florida Product Approval, not a Miami-Dade NOA. The inspector physically checks the glazing label against the NOA number. If it doesn’t match, the permit gets revoked and the whole job has to come out.
- Non-impact glass in a wind zone that demands impact. Westchester is not a “maybe” zone. Every window, even a single bathroom unit, must be impact-rated or protected. No exceptions. We’ve seen homeowners try to replace one window with a non-impact unit to save a few hundred dollars, and the county flagged it immediately.
What Window Replacement Costs in Westchester
Impact window replacement in Westchester runs roughly $800 to $1,500 per window installed for standard openings. Impact single-hungs typically land between $900 and $1,800 depending on size and design pressure. Large or custom openings, like a picture window facing the street on a corner lot off Bird Road, run $2,500 to $5,000. Whole-home packages for a typical 3-bedroom Westchester ranch fall between $8,000 and $25,000+ depending on opening count, floor height, and frame material.
What moves the price in Westchester: the number of openings, whether they’re standard or oversized, whether we’re doing a full-frame tear-out or an insert, and what design pressure the county requires for your exact location and floor elevation. Corner lots and second-story openings carry higher wind loads, which means higher-rated glass. We give you a written, line-item quote after a free in-home measure, so you see exactly what you’re paying for. Call (850) 721-1218 to schedule yours.
Florida Pays You Back
The incentives stack, and they’re real. My Safe Florida Home matching grants cover qualifying wind-mitigation upgrades up to $10,000. Florida gives you a sales-tax exemption on impact-resistant windows and doors. The federal 25C energy credit returns 30% of the product cost on qualifying units, capped at $600 per year. And after a wind-mitigation inspection ($75 to $150), most Westchester homeowners see their windstorm premium drop around 25% on the windstorm portion of their policy. We don’t set the numbers, carriers do, so we won’t promise a dollar figure. But the program stack is worth asking about.
The Salt Air Problem: Why Material Choice Matters in Westchester
Westchester’s distance from the water doesn’t protect it. We’re roughly 10 miles from Biscayne Bay, and salt-laden air travels that far without breaking a sweat. It settles on aluminum frames, works into the pores of the metal, and starts pitting within a decade. Add year-round humidity above 70% and intense UV, and window seals that last 20 years in Orlando last 10 to 12 here, sometimes less.
That’s why the cheap aluminum spec costs more within a decade. An inland-grade aluminum frame with standard fasteners will pit, bind, and start leaking around the jambs. The stainless fasteners and marine-grade finishes we specify cost more up front, but they survive. On a 1960s CBS ranch off Coral Way, we pulled out original louvered aluminum jalousies that had become so pitted from salt air and humidity the sashes no longer sealed. We reset the openings with PGT impact-rated casement units carrying current HVHZ NOAs, embedding stainless fasteners and back-sealing the jambs before the inspector verified each glazing label against the approved NOA number.
When you’re comparing quotes, ask what hardware the installer is using. If they can’t tell you, or they say “standard fasteners,” that’s your answer. The coastal-spec version of this job costs more because it has to. The inland-spec version costs less because it won’t last.
Impact Windows vs. Hurricane Shutters: The Westchester Reality
Some Westchester homeowners think shutters are the cheaper path. They’re not wrong on day one. But shutters mean you’re hanging panels in the dark during a storm, assuming they’re accessible and not stuck in a shed behind a lawn mower. Impact windows are permanent. They’re always deployed, always protecting the opening, and they never need a warning from the National Hurricane Center to start working. For a homeowner who leaves town for work or family, impact glass is the difference between a protected house and an open one. And impact windows add to your wind-mitigation credits in ways shutters don’t. That’s the bigger picture on the price gap.
Pricing for Window Replacement in Westchester, FL
A typical full-frame impact window replacement in Westchester runs $900 to $1,500 per opening. Inserts come in slightly lower, usually $700 to $1,200, when the existing frame is sound. An entire 3-bedroom ranch with 10 to 14 openings, including sliding glass doors, lands between $10,000 and $20,000 before incentives. Bigger openings, second-story work, and corner-lot wind loads push the per-unit rate toward the top of the range.
The best way to know your exact number is a free in-home measure. We walk the house, count the openings, check the frames, and give you a written quote with every line item separated. No change orders later, no “we didn’t see that” surprises. Call (850) 721-1218 to schedule your free estimate.

FAQs - Window Replacement in Westchester
Because Westchester is inside Miami-Dade County’s High Velocity Hurricane Zone, and the county requires every window and door replacement, even a single unit, to carry a Miami-Dade Notice of Acceptance (NOA). Florida Product Approval alone doesn’t cut it here. The inspector will check the glazing label against the NOA number during your permit inspection, and if it doesn’t match, the job fails and the permit gets revoked. That’s the same rule whether you’re replacing one bathroom window or fourteen openings. Call (850) 721-1218 and we’ll verify the NOA on every unit before we order.
No. Original jalousie windows are flatly non-compliant under current Miami-Dade code. The moment you pull a permit for any window work, the county will require the replacement assemblies to be impact-rated with current NOAs. If the jalousies are still in place, they’re not protecting your home from wind, water, or UV, and they’re costing you money on insurance every year. Call (850) 721-1218 for a free replacement estimate.
Yes. The HVHZ boundary covers all of Miami-Dade County, including every neighborhood in Westchester, from Coral Way to Bird Road. Distance from the water doesn’t change the wind-load requirements. Impact-rated glazing is mandatory for every replacement window in Westchester, no exceptions. Call (850) 721-1218 and we’ll walk you through the exact spec your opening requires.
In most cases, yes. After a wind-mitigation inspection, which typically costs $75 to $150, homeowners with impact-rated windows and doors see their windstorm premium drop an average of roughly 25% on the windstorm portion of their policy. Your carrier sets the final number, so we won’t promise a specific dollar figure, but the credits are well documented in Miami-Dade. Call (850) 721-1218 for details on which upgrades qualify for the biggest reduction.
Salt-laden air from Biscayne Bay, roughly 10 miles east, combines with year-round humidity above 70% and intense UV to pit and corrode aluminum frames significantly faster than in inland markets. Seals degrade sooner, sashes bind, and frames fail structurally within a decade or two. That’s why we specify stainless fasteners and marine-grade finishes on every Westchester job, and why we steer homeowners toward vinyl or impact-rated aluminum designed for coastal exposure. Call (850) 721-1218 to find out which material makes sense for your home.
