Fast, Reliable Impact Windows Across Three Lakes
Window Replacement in Three Lakes typically runs $800 to $1,500 per window installed, and because the entire CDP sits inside Miami-Dade County’s High-Velocity Hurricane Zone, every permitted job must carry a Miami-Dade Notice of Acceptance (NOA). That’s not an upsell. It’s the law. Call (904) 478-8983 for a free in-home measure and written quote from a team that has been doing HVHZ-compliant work since 2011. Ed Winslow owns this company, his name is on the door, and he stands behind every window we put into a Three Lakes home.
Why Winslow Windows & Doors Is Three Lakes’s Preferred Impact Windows Company
We’ve worked on enough concrete block ranchers off SW 268th Street and the side roads feeding into it to know exactly what Three Lakes homeowners are dealing with: houses built solid in the 1970s and 1980s, still carrying original aluminum single-pane sliders and jalousies that were legal when installed and are nowhere near legal now. Our Impact Windows team knows which permits Miami-Dade will approve, which products carry the right NOA, and how to get a county inspection scheduled without weeks of delay. That local know-how translates into fewer surprises on the invoice.
Three Lakes customers call us because we answer the phone. Not a call center. A live person, 24 hours a day, seven days a week. Every technician who shows up at a Three Lakes home is background-checked and in uniform, so you know who is at your door before the truck even parks. And our Done Right Promise means if the work is not done right, Ed makes it right. That’s a lasting standard, and it applies to every window, door, and frame we touch in Three Lakes.
Our Impact Windows Services in Three Lakes
Impact Windows
Full-frame impact window replacement is the default job in Three Lakes. Most homes here were built before Hurricane Andrew forced the post-1992 code overhaul, which means original aluminum sliders and jalousies have no path to HVHZ compliance through retrofit glazing. We pull the old frame completely, install large-missile-rated laminated glass units from NOA-approved brands like PGT and CGI, and handle the Miami-Dade permit application as part of the quote. Installed in as fast as a single day once your units arrive.

Windows & Doors
Impact-rated windows and doors have to work as a system. A compliant front entry door does you little good if the sidelights next to it still carry single-pane glass. We quote matched sets when the opening calls for it, and we carry product lines from CWS, ECO Window Systems, ES Windows, and Mr-Glass for homeowners who want an architectural look without sacrificing the wind-load rating. In Three Lakes, where salt humidity oxidizes aluminum frames fast, we recommend reinforced frame materials that will not corrode within a decade of install.

Energy-Efficient Impact Windows
The same laminated glass that stops a wind-borne 2-by-4 also cuts down on the UV that pours through South Florida windows year-round. Three Lakes homeowners see a measurable drop in cooling load once the original single-pane aluminum goes away. We spec low-E coatings and insulated frames in every quote, and the federal 25C energy credit applies to qualifying units, up to $600 per year on the product cost.

Impact Garage Doors
Three Lakes garages often sit forward of the living space, and a wind-rated garage door is a required part of any whole-home wind mitigation package. We install impact garage doors from Therma-Tru and other authorized brands, matched to the same HVHZ design pressure rating as the rest of the openings on the home.

Trusted Brands We Service in Three Lakes
We are an authorized installer for eight premium brands: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru. What matters most for Three Lakes is that these are the brands that bothered to obtain Miami-Dade NOA certifications. Most national window brands never did, which means their product sheets fail permit review before the job starts. We stock the local product, matching frames and hardware for Three Lakes jobs, so warranty claims and reorders get handled without weeks of back-and-forth.
Common Impact Windows Problems We See in Three Lakes Homes
- Jalousie windows in secondary bedrooms. These louvered glass slats are common in 1970s and 1980s Three Lakes construction. They offer zero impact resistance and cannot be reglazed, retrofitted, or upgraded into compliance. The only legal fix is full demolition and replacement with NOA-approved laminated units. We get calls every hurricane season from homeowners asking for a reglazing quote and we have to break the news.
- Corroded aluminum frames snapping during removal. Salt-laden humidity eats aluminum frames quickly in Three Lakes. When installers try to reset an original jamb, the metal often shears. That means a job quoted as a simple window replacement becomes a full-frame replacement mid-project. We quote for the full frame up front so the number does not change on you.
- Permit denials on cheap quotes. Some homeowners accept a low quote that skips the NOA paperwork and saves a few hundred dollars, only to have Miami-Dade deny the permit because the product lacks Florida Product Approval. The job stalls, the deposit is at risk, and hurricane season is not waiting. We include permit-ready NOA documentation in every quote.
- Weatherstripping failure on original sliders. Three Lakes homes from the pre-Andrew era have weatherstripping that degrades within a few years of install. Air leaks drive up cooling bills and let wind-driven rain into the wall cavity. Once the window is replaced with a properly sealed impact unit, the air leakage and the water intrusion stop.
Pricing for Impact Windows in Three Lakes, FL
Impact window pricing in Three Lakes runs $800 to $1,500 per window installed, with single-hung units landing between $900 and $1,800. Large or custom openings typically run $2,500 to $5,000 per opening. A whole-home package for a standard Three Lakes concrete block rancher lands between $8,000 and $25,000 or more, depending on opening count, frame material, and design pressure requirements. Anything requiring a large-missile-rated laminate in a tall opening will sit at the higher end.
What moves the price in Three Lakes specifically? First, the HVHZ wind zone means every opening must meet higher design pressure ratings than a typical Florida Product Approval covers. Second, the pre-Andrew housing stock requires full-frame replacement, not insert windows, which adds labor and materials. Third, floor height matters; a second-story opening on one of the few two-story homes in the area needs a heavier rating than a ground-floor slider. Call (904) 478-8983 for a free in-home measure and written line-item quote. We do not change the number once work begins.

Florida Pays You Back
Three Lakes homeowners have real incentives to offset the cost of impact windows. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact-resistant windows and doors are exempt from Florida sales tax. The federal 25C energy credit covers 30% of the product cost on qualifying energy-efficient units, up to $600 per year. After installation, a wind-mitigation inspection ($75 to $150) can unlock windstorm-premium credits that average around 25% on the windstorm portion of your policy. The exact numbers come from your carrier, not us, but the inspection report we help you get is what they look at.
One comparison worth making: impact windows versus hurricane shutters. Shutters only protect you when someone is home to deploy them, and they do nothing for UV, noise, or the cooling bill. Windows protect every hour of every day, with no panels to hang. In Three Lakes, where a storm cone can pop up fast, permanently installed laminated glass is the choice that actually gets used.
Ratings context: every unit we quote in Three Lakes carries a Miami-Dade NOA, and the design pressure rating is matched to the specific opening. We never spec anything above +/-100. The NOA number applies to each configuration, so the product sheet we hand you matches the frame, glass, and anchor system exactly. That is what passes inspection and what your insurance company wants on file. A big-box retail install is not going to walk you through the NOA paperwork with the county. We will.
What the Miami-Dade HVHZ Code Actually Forces You to Replace in Three Lakes
Every permitted impact window or door replacement in Three Lakes must carry a Miami-Dade Notice of Acceptance (NOA). The entire CDP lies within the High-Velocity Hurricane Zone, the most demanding wind-load designation in the country. That NOA is a product approval layer beyond the standard Florida Building Code, and it eliminates most national window brands from the job. Homeowners in Three Lakes are effectively working from a shortlist: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru. If a quote does not name a specific NOA number per configuration, the permit application will bounce.
We just finished a full-frame PGT casement replacement on a 1978 concrete block rancher off SW 268th Street. The original aluminum jalousies in the back bedrooms had corroded sashes and locks that would not engage, and the homeowner was shocked to learn jalousies cannot be brought into HVHZ compliance through any retrofit. We pulled the louvered frames, installed the new large-missile-rated units with laminated glass, and scheduled the county inspection that same week. That is the norm in Three Lakes, not the exception.
And that is the information gain no generic impact window page gives you: what exactly the Miami-Dade HVHZ code forces you to replace in Three Lakes’ pre-Andrew stock, and which NOA-bearing products will not get your permit bounced.

FAQs - Impact Windows in Three Lakes
Jalousie windows cannot be reglazed into HVHZ compliance. The louvered glass slat design, common in 1970s and 1980s Three Lakes homes, offers zero impact resistance and no retrofit path exists. The entire unit must be demolished and replaced with a Miami-Dade NOA-approved laminated glass window. Call (904) 478-8983 and we will tell you straight whether a reglaze is even possible on your specific openings, and what a compliant replacement would cost.
Usually the wind-mitigation inspection report is missing or incomplete. The initial permit inspection confirms code compliance, but your carrier’s premium credit requires a separate wind-mitigation inspection documenting opening protection, roof-to-wall connections, and the exact product approval numbers for every opening. We help Three Lakes homeowners schedule that inspection after install and make sure the report lists the Miami-Dade NOA numbers correctly. Without that report, the credit is not coming. Call us at (904) 478-8983 and we will walk you through it.
A Miami-Dade NOA is a stricter product approval that certifies the window meets the specific wind-load and missile-impact requirements of the High-Velocity Hurricane Zone. A generic Florida Product Approval is broader and does not automatically meet HVHZ standards. In Three Lakes, every permit application for a window or door replacement requires the NOA. Products without it will not pass plan review, and you will have wasted the application fee and the time. Our quotes include the NOA number for every unit we spec.
In Three Lakes, the design pressure rating depends on the specific opening: its size, floor height, and exposure. Most ground-floor openings in a single-story concrete block rancher need a rating between +/-40 and +/-80 pounds per square foot, but larger glazing or partial second-story elevations may push past that. We never spec above +/-100. The quote should list a design pressure number for each opening, and the NOA should match that number. If a quote does not include the DP rating and NOA number, it is not ready for permit. Call (904) 478-8983 for a quote that has both.
You do not have to replace working windows until you are changing them out. But the moment you pull a permit for any window or door replacement in Three Lakes, the new unit must meet current HVHZ code, and adjacent openings may need to be brought up if the project scope triggers it. And practically speaking, 1980s single-pane sliders offer no impact protection. The next hurricane cone is not going to wait for a retrofit. We can quote a phased replacement plan that works with your budget. Call (904) 478-8983 for a free in-home measure.
