Fast, Reliable Window Installation Across Westchester
Replacing windows in Westchester isn’t a cosmetic upgrade; it’s a code-driven retrofit. Every opening in this neighborhood sits inside Miami-Dade County’s High Velocity Hurricane Zone, which means your new windows must carry a Miami-Dade Notice of Acceptance, or the inspector fails the job and your insurer walks. We’ve spent over 15 years navigating that exact requirement on the original CBS ranch homes that dominate Westchester’s grid, from SW 8th Street down to Bird Road and everywhere off SW 87th Avenue. Call (863) 251-5864 and you’ll get Ed Winslow’s team, a real person who knows this neighborhood’s housing stock without you having to explain it.
Why Winslow Windows & Doors Is Westchester’s Preferred Window Installation Company
We’re not a national chain that subcontracted a crew from two counties away. We’ve been installing impact windows in Westchester since 2011, and Ed Winslow’s name is on the door and on every job we do. Homeowners near Tropical Park, along Coral Way, and up in the neighborhoods south of Flagler keep calling us back because we show up when we say we will, price the work honestly before we start, and don’t leave the site until the stucco patch matches and the inspector signs off.
Our technicians are background-checked and show up in uniform, so you know exactly who’s walking up your driveway before the first knock. Every call is answered by a live person, 24 hours a day, 7 days a week. No voicemail maze, no call center in another state. When you call (863) 251-5864, you reach someone who knows what a jalousie-to-impact conversion actually involves on a 1962 CBS wall.
Westchester homeowners consistently tell us the same thing: the big-box installer gave them a ticket number, and we gave them a written quote with line items and a phone number they can call at 2 a.m. That’s the difference. And our 36500-Day Done Right Promise backs every install. If it’s not done right, we make it right. Period. That’s a century-long standard of accountability no faceless chain can match.
Our Window Installation Services in Westchester
Single & Double Hung Windows
Most Westchester ranch homes were built with louvered jalousie windows or thin single-pane aluminum sliders, not vertical sashes. When we retrofit to single or double hung windows, the rough opening often needs reframing and masonry anchoring before the new unit goes in. We install PGT 5500 single hungs and other Miami-Dade NOA-approved systems that hold design pressures matched to your specific opening and wind zone, not whatever was cheapest on a shelf. For Westchester’s CBS construction, that means pressure-treated bucks, proper flashing, and a stucco patch that blends with the original wall texture.
Horizontal Roller Windows
Horizontal roller windows are a natural fit for Westchester’s low, wide openings, especially on back porches, patios, and utility rooms. The original aluminum rollers from the 1960s and 70s are almost always oxidized, pitted, and leaking air around the tracks. We replace them with impact-rated roller windows that glide cleanly, seal tightly, and meet the same HVHZ requirements as any other opening in your house. If you’re in one of the streets off SW 72nd or down by Bird Road, we’ve likely already worked on a house just like yours.
3-Panel Sliding (3-Lite Roller) Windows
Three-panel sliders are common across Westchester’s larger living rooms and Florida rooms, where a wide view mattered more to the original builder than energy performance. Replacing one without pulling a permit and meeting NOA requirements is a costly mistake. We frame these openings correctly, anchor the track system into the existing block, and install units that operate smoothly while carrying a true Miami-Dade product approval. The difference is noticeable the first afternoon the sea breeze does not whistle through the frame.
Casement Windows
Casement windows give Westchester homeowners something the original jalousies never could: a sealed, gasketed operating window that locks air and water out when the wind picks up in September. They also crank open wide to catch the afternoon breeze off the bay. On CBS ranch homes, casement retrofits require careful flashing at the masonry face and a sill design that sheds water away from the wall, not into it. We’ve done enough of these along Coral Way and the numbered streets to know exactly where failures happen when the prep work gets skipped.

Common Window Installation Problems We See in Westchester Homes
- Jalousie windows failing insurance standards: The original louvered jalousies on Westchester’s 1950s-to-1970s CBS homes have zero impact resistance and no weather seal. Miami-Dade insurers are flagging them for surcharges or outright cancellation, which is why jalousie-to-impact conversion is the single most common job category in this neighborhood.
- Skipping pressure-treated bucks on masonry walls: Anchoring a new impact window directly into 60-year-old concrete block without a pressure-treated buck causes leaks, sagging sashes, and cracked stucco within two seasons. Westchester’s CBS construction makes this prep step non-negotiable.
- Non-NOA “impact-style” windows failing inspection: A homeowner buys what looks like an impact window from a big-box store, installs it, and then fails the Miami-Dade inspection because the product has no NOA number. That’s money out the door and an insurance credit that never comes.
- No stucco patch allowance in the quote: A retrofit quote that doesn’t include matching the stucco texture on the exterior wall means the job stops halfway or leaves a mismatched patch. Westchester’s stucco finishes are textured in ways you have to match carefully, or the whole wall looks patched.
What Window Installation Costs in Westchester
We quote honest line-item pricing because Westchester homeowners have been burned by vague estimates before. A single impact window install, including the unit, anchoring, flashing, and stucco patch, typically runs $800-$1,500 per window in this market. Impact single-hung windows generally land between $900-$1,800 depending on size, floor height, and the design pressure your specific opening requires. Large or custom openings, like a wide three-panel slider or a bay conversion, run $2,500-$5,000 or more. Whole-home packages for a typical 3-bedroom Westchester ranch commonly land between $8,000 and $25,000+, driven by the number of openings, frame material, and whether we’re doing a straightforward replacement or a full jalousie-to-impact retrofit with reframing.
What moves the price in Westchester specifically: opening count, your home’s exact wind zone exposure, first-floor versus second-floor elevation, and the condition of the existing masonry around each opening. Homes with original jalousies need more prep than homes with older aluminum frames. Call (863) 251-5864 to schedule a free in-home measure and written quote. You get real numbers, not a “ballpark” that doubles later. No change orders because we missed something on the walkthrough.
Florida Pays You Back
The incentives stack up if you know where to look. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which includes impact windows in many cases. Florida also exempts impact-resistant windows and doors from sales tax, which saves you 6 to 7 percent on the whole job at purchase. The federal 25C energy credit covers 30% of the product cost, up to $600 per year on qualifying energy-efficient units. And after a wind-mitigation inspection, which runs about $75-$150 in Westchester, most homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of their policy. The exact numbers come from your carrier and the program administrators, not from us, but the stack is real and worth chasing.
Building on Acreage Around Westchester: What Actually Changes the Price
Most Westchester homes sit on standard 50-by-100 or 60-by-115 lots, but the neighborhoods south of Bird Road and out toward the edges of the grid have larger parcels, some with detached garages, outbuildings, or expanded Florida rooms that changed the original footprint. If you’re doing a whole-home window installation on one of those properties, the scope is different than a standard ranch replacement. County permitting applies across the board here, and setback and drainage considerations can affect how we approach exterior work around the foundation line. Long material hauls on narrow interior streets off SW 72nd or near the park require scoping access and staging before we quote, not after. Detached guest houses or workshops with their own windows add openings and sometimes their own wind-exposure profile. We walk the entire property before quoting because change orders are what happen when someone quotes from a satellite photo.
On one 1950s CBS ranch off SW 87th Avenue, our crew pulled out the original jalousie units and set PGT 5500 single-hung windows into pressure-treated bucks anchored into the masonry. We flashed every rough opening, tested the large-missile rating with the county inspector on site, and stucco-patched the exterior so the new frames looked original. No trim callbacks. The homeowner’s wind mitigation credit went through without a fight because the NOA paperwork matched the installed units exactly. That’s the kind of job Westchester requires, and it’s the only kind we do.

FAQs - Window Installation in Westchester
Why does Westchester require a Miami-Dade NOA for window installation when nearby cities don’t?
Westchester sits entirely inside Miami-Dade County’s High Velocity Hurricane Zone, which mandates that every window and door product carry a Miami-Dade Notice of Acceptance before it can be installed. That requirement exists because the county enforces the strictest wind-load standards in the continental US, and it applies to every opening in Westchester, no exceptions. Neighboring Broward County does not enforce the same NOA layer, which is why a window that passes inspection in Hollywood will fail in Westchester. Call (863) 251-5864 and we’ll walk you through the paperwork for your specific openings.
Can I replace my old jalousie windows with any impact window, or do I need a specific type for my CBS house?
You need a window system that carries a Miami-Dade NOA for the specific size and design pressure your opening requires, plus the right anchoring for concrete-block construction. Jalousie openings are usually wider and shorter than standard modern window rough openings, so a direct retrofit often means reframing the opening, installing pressure-treated bucks anchored into the masonry, and selecting a unit that fits the new dimensions while holding the required design loads. We scope all of that during the free estimate, not after the old windows are already out. Call (863) 251-5864 for an exact quote.
Will impact windows really lower my cooling bill in Westchester’s climate, and by how much?
Yes, by a measurable amount. Westchester’s combination of extreme UV, high humidity, and salt-laden air breaks down old single-pane aluminum frames quickly, and the air leakage through original jalousies is enormous. Impact windows with insulated glass and tight gaskets reduce that air exchange and solar gain, which typically cuts the cooling portion of the electric bill by a double-digit percentage, though the exact number depends on your home’s orientation, shading, and current insulation. The bigger guaranteed savings are on your windstorm insurance premium after a wind-mitigation inspection.
My insurance company is threatening to cancel because I still have jalousies. What exactly do I need to install to keep my policy?
You need Miami-Dade NOA-approved impact windows installed with the proper masonry anchoring and passed by a county inspection, followed by a wind-mitigation inspection that documents the new openings. The NOA is what the insurance carrier checks, and the wind-mitigation report is what actually unlocks the premium credit. We handle the installation and the inspection coordination so you don’t have to learn code language on a timeline. Call (863) 251-5864 and we’ll tell you exactly what your house needs.
Do I need a permit for window installation in Westchester, and how long does it take?
Yes, every window replacement in Westchester requires a Miami-Dade permit, and it’s not a formality. The permit review and inspection confirm the product’s NOA and the installation method match the approved product configuration. Typical permit turnaround runs a couple weeks, but custom unit fabrication adds 4-6 weeks before installation day. Once your windows arrive, installation on a standard ranch home is usually done in a single day. Call (863) 251-5864 and we’ll pull the permit, schedule the inspection, and handle the whole process.
