We know Three Lakes because we’ve worked here for years. The 1970s and 1980s CBS ranch homes off SW 120th Street, the wider lots that back up to the lake chain, the original aluminum jalousies that rattle when the afternoon storms roll through. This is our backyard, and we treat every job like the homeowner is a neighbor. Because they are.
Why Winslow Windows & Doors Is Three Lakes’s Preferred Energy-Efficient Windows Company
Ed Winslow started this company in 2011, and his name still goes on every invoice, every permit application, and every job we do. That’s not a slogan. It’s how we’re built. When a Three Lakes homeowner calls us about a failed window seal or a jalousie that won’t close, they’re not getting a ticket number from a call center. They’re getting Ed’s team, a live person who knows the local code requirements, and a crew that shows up in uniform with a background check already on file.
Three Lakes sits inside Miami-Dade County’s High Velocity Hurricane Zone, or HVHZ. That single fact changes everything about window replacement here. The product rules are stricter than anywhere else in Florida, including just across the county line in Broward. We’ve handled enough HVHZ replacements in Three Lakes to know exactly which products carry the right Miami-Dade Notice of Acceptance, and we post that NOA number on-site before the inspector shows up. No reinspections. No delays. No guesswork.
Our Energy-Efficient Windows team works Three Lakes regularly. We answer the phone 24/7, and every standing offer applies here: $40 off any repair over $200, a free second opinion on any written estimate, no trip charge for homes in our home county, and a permanent 10% discount for seniors and veterans.
Our Energy-Efficient Windows Services in Three Lakes
Window Energy Audits & Ratings
Before we quote a single window, we’ll look at what’s actually happening in your Three Lakes home. That means checking the U-factor and Solar Heat Gain Coefficient on your existing glass, testing for seal failure, and looking at how each opening faces the afternoon sun. Older CBS homes in Three Lakes often lose the most energy through west-facing sliders and jalousies, and an audit tells us exactly where your dollars are bleeding out.

Insulated Laminated Glass
In Three Lakes, insulated laminated glass does double duty. The insulating air space cuts heat transfer, and the laminate layer holds the glass together if something hits it. It’s the right product for homes near the lakes where wind-driven debris is a real concern during storm season, and it’s what we’ll recommend for most replacement openings here.

Low-E & Argon Gas Glass
Low-E coatings reflect infrared heat away from the home while letting visible light through. That matters in Three Lakes, where the summer sun hits hard from June through September and cooling costs climb every afternoon. Argon gas between the panes adds another layer of insulation. We’ve seen Three Lakes homeowners cut cooling costs 20 to 30 percent after upgrading from original single-pane aluminum to Low-E argon units.

UV-Blocking & Fade Protection
Sun fading on furniture, floors, and artwork is a constant battle in South Florida. The right UV-blocking glass keeps your interior from bleaching out year after year. For Three Lakes homes with large east-facing living room windows or wide sliding glass doors, this upgrade pays off faster than most people expect.

Trusted Brands We Service in Three Lakes
We install energy-efficient windows from brands that meet Miami-Dade’s HVHZ requirements. In Three Lakes, we frequently work with PGT, CGI, and ES Windows products. These manufacturers all carry the Miami-Dade NOA paperwork required for replacements here, and we stock common hardware and parts locally so turnaround stays tight. If a window needs a replacement latch or balance, we’re not waiting on a slow national supply chain.
Common Energy-Efficient Windows Problems We See in Three Lakes Homes
- NOA mismatch on replacements. A contractor installs a window with a Florida Product Approval from Broward but no Miami-Dade NOA. The permit gets rejected, the product has to be swapped, and the homeowner eats the delay. We verify the NOA before ordering.
- Salt-air corrosion on aluminum frames. Three Lakes sits roughly 12 to 15 miles inland from Biscayne Bay, but salt-laden air still works its way in. Original jalousie hardware seizes or pits within a few years, breaking the seal and letting wind-driven rain push through during afternoon thunderstorms.
- Septic and well setback conflicts on larger lots. Some Three Lakes homes sit on acreage with septic drain fields and wells. A new window or door rough opening can encroach on the required setback, which forces a redesign after the hole is cut. We scope setbacks before we quote, not after.
- Wide slider openings that lose conditioned air. The 1970s-through-1990s tract homes here often feature wide sliding glass door openings. When seals fail, these big glass areas leak cooled air all summer. Replacing them with insulated laminated glass units closes the gap.
Pricing for Energy-Efficient Windows in Three Lakes, FL
A typical impact-rated, energy-efficient replacement window in Three Lakes runs $800 to $1,500 per opening installed. Single-hung impact units fall between $900 and $1,800. Large or custom openings, like a picture window or a wide slider, run $2,500 to $5,000. Whole-home packages on a 1970s or 1980s CBS ranch usually land between $8,000 and $25,000 depending on how many openings you have and what’s being pulled out.
What moves the price here? Opening count is the biggest driver. Wind zone already pushes every Three Lakes home into strict HVHZ territory, so there’s no budget-friendly code exception to chase. Frame material matters, and floor height can affect access and labor. On acreage lots, we also look at septic and well setbacks before finalizing the layout. Call (844) 901-4551 for a free in-home measure and a written quote. It’s fixed pricing, no change orders down the line.
What Energy-Efficient Windows Costs in Three Lakes
The numbers above are real anchors for this market. Impact windows in Three Lakes generally run $800 to $1,500 per window installed. Impact single-hung units sit in the $900 to $1,800 range. Large or custom openings go $2,500 to $5,000. Whole-home packages across a full 1970s ranch or two-story CBS home run $8,000 to $25,000 or more, depending on opening count and product line.
Three Lakes carries an extra cost layer that most other Florida markets don’t: the HVHZ means every unit must carry a Miami-Dade NOA. That’s not optional, and it’s not the same as a Florida Product Approval. We’ll never install a window in Three Lakes that doesn’t carry the right NOA number for its specific configuration. It’s why our quotes here are sometimes slightly higher than what a homeowner hears from a Broward-only contractor. The alternative is a failed inspection and a window that has to come back out.
We scope every job before we quote: opening count, wind zone, frame material, floor height, septic and well setbacks on acreage lots, and access for material hauling on long driveways. All of that goes into the written estimate. Call (844) 901-4551 for a free in-home measure.
Florida Pays You Back
Florida and the federal government offer a few ways to offset the cost of energy-efficient, impact-rated windows in Three Lakes. The My Safe Florida Home program has provided matching grants of up to $10,000 for qualifying wind-mitigation upgrades, though funding windows open and close. Florida also exempts impact-resistant windows and doors from sales tax, which can save you hundreds on a whole-home package. On the federal side, the 25C energy credit covers 30 percent of the product cost on qualifying units, up to $600 per year.
Homeowners in Three Lakes who replace original single-pane jalousies with impact-rated, energy-efficient units often see windstorm premium credits after a wind-mitigation inspection. Those inspections run $75 to $150, and the credit on the windstorm portion of the premium averages around 25 percent. Your carrier sets the final number, and we can’t guarantee a specific credit. But the inspection is cheap, and the savings tend to stack.
One thing we hear from Three Lakes homeowners: impact windows beat hurricane shutters for the simple reason that you never have to think about them. Panels sit in a shed. Impact glass is always in place. When a storm comes through, your home is already protected, and you’re not outside on a ladder fumbling with hardware in the wind.
Building on Acreage Around Three Lakes
Plenty of Three Lakes homes sit on larger lots. Not city-sized lots, but real acreage with septic systems, wells, outbuildings, and long driveways. That changes how we scope a window or door replacement, and we factor all of it into the quote before we cut a single opening.
County permitting rather than city permitting is the rule here. Miami-Dade inspectors work off the same code regardless, but the paperwork path is different, and the NOA matching requirement gets enforced hard. Septic and well setbacks are the other big one. A new window or sliding glass door rough opening can’t encroach on the required setback from a drain field or well head. We measure those distances before we finalize the design. If the opening doesn’t work, we move it before the hole gets cut, not after.
Long material hauls and equipment access also matter. A crane can’t always get close to the structure on a heavily treed lot, and that changes labor. Outbuildings, detached shops, and ADUs have their own window and door requirements, and we handle those as part of the same package. Grading and drainage on an open lot affects how door thresholds need to be set so wind-driven rain doesn’t pool at the sill. We walk all of it before we quote.
On a 1978 CBS ranch off SW 120th Street, we replaced eight original jalousie windows and a wide sliding glass door with PGT impact-rated casement and picture windows using insulated laminated glass. The homeowner had already cut cooling costs 20 to 30 percent with our Low-E argon gas units, and we posted the Miami-Dade NOA for each product before the inspector’s first visit. No reinspection needed. That’s what scoping the job right up front buys you.

FAQs — Energy-Efficient Windows in Three Lakes
Three Lakes sits entirely within Miami-Dade County’s High Velocity Hurricane Zone, the only jurisdiction in Florida that requires every replacement window and door to carry a Miami-Dade Notice of Acceptance. A Florida Product Approval from Broward is not enough here. The NOA certifies that the specific product passed large-missile impact testing, which is a stricter standard than the pressure-based approvals used elsewhere. If you install a window without the right NOA, the inspector will fail the job and you’ll pay to have the product swapped. Call (844) 901-4551 and we’ll verify the NOA before we order anything.
Yes, in most cases. Homes in Three Lakes that replace original single-pane jalousies with impact-rated, NOA-certified units typically see windstorm premium credits after a wind-mitigation inspection. Those inspections run $75 to $150, and the credit on the windstorm portion of the premium averages around 25 percent. Your insurance carrier sets the final number. We’ll provide the product documentation your inspector needs. Call (844) 901-4551 and we’ll walk you through it.
Yes. In Miami-Dade County, new window and door rough openings cannot encroach on the required setback from a septic drain field or well head. We measure those distances before we finalize the design. If the opening needs to move, it moves before the hole is cut, not after. Call (844) 901-4551 for a free on-site measure and scope.
Yes, still. Shading from mature oaks helps reduce direct solar gain, but ambient heat and humidity still push through single-pane aluminum frames around the clock. Low-E coatings and argon gas reduce both radiant and convective heat transfer, which lowers cooling loads even on shaded lots. We’ve seen Three Lakes homeowners cut cooling costs 20 to 30 percent after replacing original jalousies with Low-E argon units, shaded lot or not. Call (844) 901-4551 and we’ll run the numbers on your home.
Look for the Miami-Dade NOA number on the product documentation. Every replacement window in Three Lakes must carry an NOA that matches the specific product configuration being installed, and that number must be posted on-site and matched to the permit. If a contractor can’t show you the NOA, the window isn’t code-legal here, no matter how energy-efficient it is. We handle this on every job. Call (844) 901-4551 and we’ll confirm the paperwork before ordering.
