Fast, Reliable Impact Windows Across Three Lakes
Impact window replacement in Three Lakes typically runs $900-$1,800 per opening for standard sizes, with whole-home packages landing between $8,000 and $25,000 depending on the count and custom work. The bigger variable here isn’t the glass. It’s whether the unit carries an active Miami-Dade Notice of Acceptance, because a Florida Statewide Product Approval alone won’t pass a Three Lakes permit inspection. That’s the first thing we check on every estimate, and it’s the reason homeowners call us instead of gambling on a cut-rate crew from out of county.
We’ve spent years working the canal-laced streets between SW 184th Avenue and the Turnpike edge, replacing post-Andrew aluminum assemblies that are now 30-plus years old and failing under humidity most window salesmen never mention. Call (727) 291-4678 and you’ll get a live person who knows Three Lakes, not a call center in another state. Ed Winslow’s name is on the door, and it’s on every job we do here.
Why Winslow Windows & Doors Is Three Lakes’s Preferred Impact Windows Company
We’re locally owned and owner-operated since 2011, with a published address and license number. No shell companies, no ticket numbers. Homeowners in Three Lakes know Ed Winslow personally, and they know that if something isn’t done right, the Done Right Promise means we come back and make it right. Not for a year. For a standard of accountability written into every job.
Our technicians show up in uniform, background-checked, and they know the difference between a 1993 CWS aluminum slider and a 2005 CGI casement by the frame profile alone. That matters when you’re deciding whether to repair or replace. We don’t sell you a one-size-fits-all quote. We walk the opening, check the NOA label, measure the design pressure, and write a line-item price before you ever commit.
When Three Lakes homeowners call us, the phone is answered by a real person 24/7. Not a voicemail loop. Not a next-business-day callback. We coordinate dispatch from our South Florida metro office and schedule crews into Three Lakes on a regular rotation, so you’re never waiting on a contractor from another county to figure out the local permit requirements.
Our Impact Windows Services in Three Lakes
Impact Window Replacement
Most Three Lakes homes still carry the original impact assemblies installed during the post-Hurricane Andrew rebuild wave of the early-to-mid 1990s. Those windows are now 30-plus years old, with frames oxidizing at the jambs and interlayers delaminating at the bottom rails. We replace them with new Miami-Dade NOA-compliant units sized to the opening, not just swapped for whatever’s on the truck. A standard replacement runs $900-$1,800 per window installed.

Sliding Glass Doors
The canal-facing CBS homes off SW 184th Avenue see constant humidity that eats aluminum door frames from the inside. We recently pulled a 1993 aluminum slider where the original impact frame showed white oxide pitting and the laminated interlayer had begun separating. The old NOA label was gone, which meant the homeowner couldn’t verify compliance for insurance. We installed a PGT vinyl slider with a fresh wind-mitigation certificate and resolved a permit rejection at the counter before inspection ever happened. Sliding door replacements in Three Lakes typically run $2,500-$5,000 for standard openings.

Low-E Insulated Impact Glass
Impact glass doesn’t have to be dark or cloudy. Low-E insulated impact units give you both the Miami-Dade large-missile rating and the solar heat rejection that keeps a west-facing Three Lakes living room from baking in August. We install Low-E packages from PGT, CGI, matched to the orientation of each opening, not spec’d blindly from a catalog. Expect to add $150-$350 per window over standard clear impact glass.

Hurricane Shutters vs. Impact Windows
Some homeowners in Three Lakes ask whether shutters are enough. Shutters stop debris while they’re up, but they don’t exist until you hang them. Impact windows are always on, always rated, and you never have to drag panels out of a garage at 11 p.m. when a storm shifts toward the Florida Straits. If you want permanent protection without the pre-storm scramble, impact windows are the answer. Whole-home replacement packages here run $8,000-$25,000+ depending on opening count.

Trusted Brands We Service in Three Lakes
We’re an authorized installer for PGT, CGI, among others, and we keep current on each brand’s active Miami-Dade NOA numbers because that’s what the Three Lakes permit counter checks first. If you already have impact windows and one unit needs replacement, we can match the existing frame profile when the brand still supports it. If the product line has been discontinued or its NOA has lapsed, we’ll tell you honestly and spec a compliant replacement rather than patch something that will fail inspection. Local parts availability for PGT and CGI means faster turnaround for Three Lakes customers who need a single window matched to the rest of the house.
Common Impact Windows Problems We See in Three Lakes Homes
- Aluminum frame oxidation at the jamb and sash. The humidity near Three Lakes’s canal-laced wetlands causes salt-air pitting even without direct coastal spray. Frames that look fine from the outside are often corroded inside the track, binding the sash and compromising the seal.
- Silicone seal and glazing tape breakdown. After 10-15 years, the sealant around the insulated glass unit deteriorates far faster in Three Lakes than in drier inland neighborhoods. During a Miami-Dade HVHZ inspection, a failed seal can make the large-missile rating unverifiable, even if the glass is intact.
- Delaminating 1990s laminated interlayers. The original impact glass installed after Andrew used laminated interlayers that were rated for the design pressures of 1993. Many no longer meet current NOA requirements, and repair parts often lack a current Miami-Dade Notice of Acceptance, forcing full replacement.
- Pre-Andrew jalousie or single-pane aluminum windows. A smaller share of Three Lakes homes still carries these unprotected openings. Under current permit requirements, they don’t qualify for repair. They require full system replacement with NOA-compliant impact units.
Pricing for Impact Windows in Three Lakes, FL
Standard impact windows in Three Lakes run $800-$1,500 per window installed at the lower end, with better frames and Low-E glass pushing that to $900-$1,800. Large or custom openings like picture windows, radius tops, or oversized sliders land between $2,500 and $5,000. Whole-home packages start around $8,000 and climb past $25,000 for larger CBS homes with many openings. What moves the price here is the opening count, the wind zone design pressure, the floor height, and whether you choose aluminum or vinyl frames. We give every Three Lakes homeowner a free in-home measure and a written, line-item quote before any work starts. Call (727) 291-4678 to schedule yours.
What Impact Windows Costs in Three Lakes
Let’s get specific. Impact windows in Three Lakes generally cost $800-$1,500 per window installed. Single-hung impact units run $900-$1,800, depending on frame material and glass package. Large or custom openings, including oversized sliders and picture windows, range $2,500-$5,000. Whole-home packages typically fall between $8,000 and $25,000+ for a full CBS house.
In Three Lakes, the cost drivers are the number of openings, the design pressure required for your specific wind zone, the floor height, and whether you’re matching an existing frame profile or doing a clean replacement. A canal-front home with 20-plus openings and elevated floor heights will naturally land higher than a small inland ranch. We don’t quote over the phone blindly. We schedule a free in-home measure, write the line-item price, and you decide. Call (727) 291-4678 to book yours.
Florida Pays You Back
Florida’s incentive stack makes impact windows cheaper than the sticker price suggests. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit returns 30% of product cost, up to $600 per year, on qualifying energy-efficient units. And most insurance carriers apply a windstorm-premium credit averaging around 25% on the windstorm portion of your policy after a wind-mitigation inspection, which typically costs $75-$150. No guarantees. Programs and carriers set the final numbers. But the stack is real, and we can point you to the paperwork.
The Materials That Survive Three Lakes Humidity
Three Lakes sits at the western fringe of Miami-Dade’s developed grid, immediately adjacent to canal-laced wetland drainage. That means window frames and door hardware here see persistently elevated humidity well above what you’d find in coastal Kendall or Pinecrest. Aluminum pitting and silicone seal breakdown happen faster. Salt air doesn’t need to be oceanfront to do damage. It rides the canal breeze and settles into every jamb, every track, every screw head.
So we specify differently in Three Lakes. Marine-grade stainless hardware on every moving part. Hot-dip galvanized fasteners instead of zinc-plated. Sealed joints with commercial-grade silicone and butyl tape, not builder-grade caulk. The coastal-spec version of an impact window install costs more upfront, around 10-20% over the inland-spec version. But the cheap spec fails within a decade. We’ve pulled hardware out of Three Lakes homes that was installed six years ago and looked forty years old. The price gap is the cost of doing it once instead of twice.
This page tells you exactly which materials and certifications survive a Three Lakes canal-humidity environment and a Miami-Dade HVHZ inspection, and why the cheaper inland spec fails within a decade. If a quote looks too good to be true, ask one question: does the product carry an active Miami-Dade NOA, not just a Florida Statewide Product Approval? If the answer is no or a shrug, walk away.

FAQs - Impact Windows in Three Lakes
Three Lakes is inside Miami-Dade County’s High Velocity Hurricane Zone (HVHZ), which requires an active Miami-Dade Notice of Acceptance, not just Florida Statewide Product Approval, on every window and door replacement. A product legal in Broward or Collier County will be rejected at the Three Lakes permit counter. The NOA confirms the product passed Miami-Dade’s stricter large-missile and design-pressure testing. Call (727) 291-4678 and we’ll verify your existing units’ compliance before you spend a dollar.
Most Three Lakes homes were built or heavily renovated after Andrew’s ground-zero pass through southern Miami-Dade in 1992, and those original impact assemblies are now failing. Frames are oxidizing, interlayers are delaminating, and many units no longer meet current NOA design pressures. Full replacement is usually the only path to compliance. We give free estimates, and we’ll tell you honestly whether a single unit can be matched or the whole wall needs to go.
Humidity near the canal-laced wetlands accelerates aluminum pitting and silicone breakdown, so we specify marine-grade stainless hardware and hot-dip galvanized fasteners on every Three Lakes install. The coastal-spec version costs 10-20% more than inland-spec, but the cheap version fails within a decade. Call (727) 291-4678 and we’ll show you the difference on the quote.
Yes. Most carriers apply a windstorm-premium credit averaging around 25% on the windstorm portion of your policy after a wind-mitigation inspection, which runs $75-$150. You may also qualify for My Safe Florida Home grants up to $10,000, Florida sales-tax exemption on impact windows and doors, and the federal 25C energy credit of 30% up to $600 per year. We’ll help you understand which incentives apply to your Three Lakes home.
Full replacement. Jalousie and single-pane aluminum windows from before Andrew do not meet current Miami-Dade HVHZ code, and repair parts lack a current Notice of Acceptance. The permit office will not approve a repair on those openings. Replacement is the only compliant path, and we’ll walk you through the cost, the timeline, and the incentive stack. Estimates are free.
