Fast, Reliable Impact Windows Across Three Lakes
If you live in Three Lakes, you already know the drill: every window you put in your house has to meet Miami-Dade’s High Velocity Hurricane Zone code. That’s not a suggestion. It’s the law, and it’s stricter here than almost anywhere else in the country. Winslow Windows & Doors handles HVHZ-compliant Impact Windows for Three Lakes homeowners every week, from initial measure to final inspection. Call (850) 930-1813 and Ed Winslow will make sure your project is done right, permitted, and inspected, with no surprises on the invoice.
Why Winslow Windows & Doors Is Three Lakes’s Preferred Impact Windows Company
Three Lakes isn’t just another stop on our route. It’s a community we know block by block, from the post-Andrew rebuilds along SW 152nd Terrace to the older ranches near Three Lakes Park. We understand that homes here fall into two camps: the pre-1992 originals with jalousie windows that wouldn’t stop a thrown baseball, and the 1990s rebuilds whose first-generation impact glass is now fogging, delaminating, and failing at the seals. Nobody else talks about that split because most crews don’t know it exists. We do.
Winslow has been locally owned and owner-operated since 2011. Ed Winslow’s name is on the door, and on every job we do. When you call (850) 930-1813, a live person answers, 24/7, not a voicemail loop. Our technicians are background-checked and arrive in uniform, so you know exactly who’s at your door before the truck pulls up. We publish our address and license number, and we stand behind every install with the Done Right Promise: if it’s not done right, we make it right. Period.
Our Impact Windows Services in Three Lakes
Impact Window Replacement
Most Three Lakes calls we get are replacements, not first-time installs. The 1990s post-Andrew generation of laminated impact glass is hitting the end of its service life. You’ll see fog between the panes, water staining around the jambs, and hardware that’s worn loose from years of salt air and humidity. We tear out the old sashes, check the rough opening for rot or corrosion, and install new units that carry a current Miami-Dade NOA, not a grandfathered approval from 1994.

HVHZ Compliance Retrofits
If your Three Lakes home still has jalousie or louvered aluminum windows, you’re living with openings that can’t pass any meaningful wind-mitigation inspection. We replace them with impact-rated single-hungs, casements, or picture windows matched to the design pressure each opening requires. The difference shows up fast: lower windstorm premiums, a quieter house, and actual protection when the next storm tracks through southern Miami-Dade.

Impact Sliding Glass Doors
Sliding doors take more abuse in Three Lakes than almost any other opening. Salt air drifting in from Biscayne Bay pits the aluminum tracks, and the constant humidity works on the rollers and weatherstripping. We install impact-rated sliding glass doors from PGT and CGI that carry Miami-Dade NOAs for the exact configuration you’re buying, including the frame, glass, and hardware combined.

Custom and Geometric Impact Windows
Some of the older Three Lakes homes have arch tops, radius corners, or trapezoid openings that big-box stores won’t touch. We fabricate through our authorized brand partners, including ES Windows and ECO Window Systems, to match the original geometry while meeting current HVHZ structural requirements. Every custom unit still has to go through the same NOA and inspection process, and we handle that paperwork for you.

Trusted Brands We Service in Three Lakes
We’re an authorized installer for eight premium brands, and for Three Lakes specifically we lean on the lines that carry the deepest catalog of Miami-Dade NOA-approved configurations. PGT WinGuard and CGI are the workhorses for most replacements. For custom geometry and higher-end architectural look, we turn to ES Windows and ECO Window Systems. For door packages, Therma-Tru remains a top choice. When a Three Lakes homeowner comes in with a failed window from a brand we don’t carry, we’ll still service it if parts exist, and we’ll tell you honestly when replacement makes more sense than repair.
Common Impact Windows Problems We See in Three Lakes Homes
- Delaminated 1990s impact glass. The laminated interlayers in early post-Andrew windows are separating between the panes, leaving cloudy, fogged glass that no longer performs to its original rating. The frame can look fine while the glass quietly loses structural integrity.
- Corroded aluminum frames from salt air. Biscayne Bay is only a few miles east, and that salt-laden breeze accelerates oxidation on uncoated aluminum frames and thresholds. Pitting around the jamb and sill is the tell. Once corrosion reaches the anchor points, the window’s hold-down strength drops.
- Non-NOA windows that pass nowhere. Some homeowners bought “impact windows” from out-of-county suppliers that carry a generic Florida Product Approval but no Miami-Dade NOA. Those fail plan review in Three Lakes, forcing a reorder, a delay, and a second permit cycle.
- Jalousie windows still in place. Pre-Andrew homes sometimes retain the original louvered glass. They rattle, leak, and offer zero projectile protection. More importantly, no insurance wind-mitigation credit is possible while they remain installed.
Pricing for Impact Windows in Three Lakes, FL
A typical replacement impact single-hung in Three Lakes runs $900 to $1,800 per window installed, depending on opening size, floor height, and required design pressure. Standard casements and picture windows fall roughly in the same range. Large or custom openings, including radius tops and oversized sliders, run $2,500 to $5,000 each. Whole-home packages on a three-bedroom Three Lakes house typically land between $8,000 and $25,000 or more, driven by opening count, frame material, and the structural fastening pattern each elevation requires. Every quote is written, itemized, and fixed before we start. Call (850) 930-1813 for a free in-home measure and a line-item proposal.
What Impact Windows Costs in Three Lakes
Impact windows generally run $800 to $1,500 per window installed at the entry level. From there, the numbers move based on what your specific openings demand. Impact single-hungs land between $900 and $1,800 installed. Large or custom openings, the arch tops and radius units common in the older parts of Three Lakes, push $2,500 to $5,000 each. Whole-home packages on a typical Three Lakes ranch or post-Andrew two-story range from $8,000 to $25,000 and up, with the total driven by opening count, elevation wind zone, floor height, and whether you choose vinyl, aluminum, or premium thermal frames.
Three factors move the price more than anything else here. First, wind zone: Miami-Dade’s design wind speeds of 175 to 185 mph mean every opening on certain elevations needs a higher structural rating, and that changes the frame and fastening spec. Second, mandatory inspections: we build the rough-opening inspection into the schedule and the price, because skipping it stalls the permit and leaves the house open. Third, the NOA: every unit you buy has to carry a Miami-Dade Notice of Acceptance for that exact configuration, and units without it get rejected at plan review. A cheap quote that doesn’t include the inspection, the NOA documentation, and the right fastening pattern isn’t cheaper. It’s just incomplete. We put all of it in the written quote, line by line, before you sign anything. Call (850) 930-1813 for your free in-home measure and written estimate.
Florida Pays You Back
The incentives stack if you know where to look. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows are one of the primary qualifying improvements. Florida also exempts impact-resistant windows and doors from sales tax at the point of purchase. On the federal side, the 25C energy credit can return 30% of the product cost, up to $600 per year, on qualifying energy-efficient units. Then there’s the insurance piece: after a wind-mitigation inspection, which runs roughly $75 to $150, many Three Lakes homeowners see their windstorm premium drop by around 25% on the windstorm portion. Programs change and carriers set final numbers, so we won’t promise a figure. We will give you the documentation your insurance company needs, including NOA numbers and the inspection sign-offs, so the credits actually process.

FAQs - Impact Windows in Three Lakes
Yes. The NOA requirement applies to the product you install now, not the age of the house. Even if the original windows were compliant in 1994, the replacement units must carry a current Miami-Dade Notice of Acceptance for the exact configuration being installed. Older NOAs lapse, products change, and the county requires current documentation at plan review. Call (850) 930-1813 and we’ll verify NOA compliance on your quote before you spend a dime.
After the old window is pulled and the new unit is anchored into the rough opening, but before any trim or interior casing goes on, a Miami-Dade building inspector must sign off on the structural connection. Experienced local crews schedule this inspection in advance so the inspector arrives the same day. Out-of-county crews that skip it get caught with the opening exposed for days. We build the inspection into the contract schedule from day one, so the house stays weathertight and the permit doesn’t stall.
Usually, yes. A wind-mitigation inspection documents the NOA-rated openings, and that documentation is what insurers use to apply windstorm credits. Homeowners here routinely see meaningful reductions on the windstorm portion of the premium, often in the range of 25%, but the final number belongs to your carrier. We provide the NOA numbers, installation photos, and inspection sign-offs in the format insurers request. Call (850) 930-1813 and we’ll get you the paperwork your agent needs.
Jalousies survive on pre-Andrew homes where owners haven’t been forced to replace them, usually because the house hasn’t sold recently and insurance renewals never triggered a mitigation push. But no, they cannot pass any HVHZ impact inspection. Louvered glass doesn’t resist wind pressure or projectile impact, and the frames leak air constantly. Replacing them with NOA-rated impact windows is the single biggest upgrade you can make to a 1960s-era Three Lakes home, both for safety and for premium reduction.
No. Miami-Dade’s approval covers the entire assembly: frame, glass, and hardware tested together as one unit. Swapping glass into a 30-year-old pitted frame breaks the NOA and fails plan review. If the frame has visible corrosion at the threshold or jamb anchors, the whole unit needs replacement with a new NOA-rated assembly. Call (850) 930-1813 for an honest assessment, even if the answer is that you don’t need us yet.
