Fast, Reliable Window Installation Across Three Lakes
Window installation in Three Lakes isn’t like window installation in most of Florida. This community sits entirely inside Miami-Dade County’s High Velocity Hurricane Zone (HVHZ), which means every replacement window must carry an active Miami-Dade Notice of Acceptance (NOA), not just a Florida Product Approval. That single fact changes who you can hire, what products qualify, and what the job costs. We’re Winslow Windows & Doors, and we’ve been handling HVHZ-compliant installations since 2011. Our Window Installation team works in Three Lakes regularly. Call (727) 620-6983 and a live person picks up, day or night.
Key Takeaways:
- Three Lakes homes fall under the strictest wind-load code in the country. Any window going in must have a Miami-Dade NOA or the county can flag it and your insurer can reject the wind mitigation credit.
- Full replacement is almost always the answer here. Original single-pane aluminum frames from the 1970s through early 1990s can’t be retrofitted to current impact standards.
- Expect to pay between $900 and $1,800 per opening for most impact-rated units, before any grants or tax exemptions.
- We quote in writing after a free in-home measure, and we scope septic and well setbacks on acreage lots before we ever hand you a number.
Why Winslow Windows & Doors Is Three Lakes’s Preferred Window Installation Company
Ed Winslow’s name is on our Door Installation in Three Lakes and on every job we do. We’re not a national chain that subcontracts your window install to a rotating crew. We’re a locally owned company founded in 2011, authorized to install PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru. When you call us about Three Lakes work, you talk to someone who knows the difference between a CBS ranch off SW 87th Avenue and a newer frame home near the Turnpike. That matters when we’re sizing impact units to existing concrete block openings.
Our techs arrive background-checked and in uniform. The phone gets answered by a real person 24/7, so when an August storm rips through and you’re staring at a cracked pane at 2 a.m., you reach us, not a voicemail tree. We publish our address and license number. We don’t hide behind a website form.
In Three Lakes, most of the work we do is complete replacement of the original aluminum windows that went in when these homes were built. Those units were engineered for a different code era. We quote the full scope up front, we pull the right permits, and we document the large-missile ratings your insurance carrier needs after the job’s done. That’s how a locally owned company should operate here.
Our Window Installation Services in Three Lakes
Casement Windows
Casements are the window we most often recommend for older Three Lakes CBS ranches where the original jalousie or aluminum slider openings need complete reworking. Because a casement cranks outward and seals against the frame, it generally performs better under HVHZ wind pressure than a vertical slider. On a 1970s concrete block home off SW 87th Avenue, we pulled corroded jalousie windows, set PGT impact-rated casements into fresh masonry bucks, and anchored them to code. The homeowner had an insurance nonrenewal letter demanding Miami-Dade NOA glazing. After install, we documented the large-missile rating for their wind mitigation credit.

3-Panel Sliding (3-Lite Roller) Windows
For the long living-room walls common in Three Lakes ranch layouts, our Sliding Glass & Patio Doors in Three Lakes like the 3-lite roller are often the most functional option. These units span wide openings and let in the same Gulf air the old single-pane sliders did, except now they close tight against debris and wind. The key on a CBS wall is anchoring. We core into concrete block and bolt the frame with proper masonry anchors, because drywall screws into stucco are not a code-compliant installation in an HVHZ zone. If your original builder hung sliders with undersized headers, we scope that on the measure.

Single & Double Hung Windows
Many Three Lakes bedrooms were built with single-pane aluminum vertical sliders, and homeowners often swap them for impact-rated single or double hungs. Double hungs give you ventilation control and easier cleaning, but we’re honest about the price difference: a good impact double hung runs higher per opening than a casement in some configurations. In an HVHZ, the unit itself has to be Miami-Dade NOA approved. We never install a Florida Product Approval-only window in Three Lakes and call it an impact window.

Picture & Fixed Windows
For the back of a home facing open Everglades edge, fixed picture windows are the cleanest way to hold a view while meeting wind-load requirements. These are large, heavy units, so on an acreage lot with a long driveway and soft ground, we send the right equipment and plan the carry path before install day. No surprises on the invoice because we scoped it first.

Trusted Brands We Service in Three Lakes
We’re authorized to install eight premium brands, and in Three Lakes we lean on PGT and Mr-Glass most often because their MVHZ configurations and available design pressures cover the elevations we see. We also service and install Therma-Tru doors for front entries that need the same Miami-Dade NOA documentation. Since we’re a Window Installation in Three Lakes crew, we keep measurements and local permit requirements top of mind. Parts and replacement units move faster when the company you hire already works in the county every week.
Common Window Installation Problems We See in Three Lakes Homes
- Corroded aluminum frames hidden behind stucco. The outside looks fine, but once we remove the old unit, the frame’s eaten through. We replace the buck and anchor properly before a heavy impact laminate unit goes in. Skipping that step means leaks and rotted drywall inside a year.
- Contractor installs a “impact” window with Florida Product Approval but no Miami-Dade NOA. Miami-Dade code enforcement flags it, and the homeowner’s insurer rejects the wind mitigation credit. We’ve had to correct several of these in Three Lakes. Make sure your quote lists the Miami-Dade NOA number for every unit, not just the product line name.
- Acreage lots and unnoticed septic or well setbacks. If a new sunroom or garden window is planned, the opening might be too close to a septic drain field or well. Moving a window six feet later means cutting concrete block and pulling permits twice. We check the property survey before we quote.
- Insurer pressure catching homeowners off guard. A lot of Three Lakes residents think accordion shutters make them hurricane ready. Then their carrier sends a nonrenewal letter demanding documented NOA impact glass. The replacement conversation shifts from “someday” to “this season,” and we help them sort the scope quickly.
Pricing for Window Installation in Three Lakes, FL
A typical impact window in Three Lakes runs $900 to $1,800 per opening installed, depending on size and product line. A basic impact single-hung starts around $900, while a large picture unit or a bay configuration lands in the $2,500 to $5,000 range. Whole-home packages on older ranches usually fall between $8,000 and $25,000 or more, driven by opening count, elevation, and whether you’re doing casements or sliders. Three Lakes pricing also reflects the cost of HVHZ documentation and masonry anchoring into concrete block, which doesn’t apply in non-HVHZ parts of Florida.
What Window Installation Costs in Three Lakes
Here’s what moves the number in Three Lakes specifically. First, opening count and window type. Casements cost more than single hungs because of hardware and hardware and the frame engineering required in an HVHZ. Second, floor height and exposure. A two-story CBS home facing open Everglades edge needs a higher design pressure than a ground-floor window in a cluster of homes. Third, frame material and anchoring. Frames that match the architectural style cost more than standard white, and any opening where the old aluminum buck is corroded adds labor. Fourth, heavy equipment access. On acreage lots with soft ground or a long driveway, we plan for a helper crew and equipment access. That gets scoped before the quote.
Call (727) 620-6983 and we’ll schedule a free in-home measure. You’ll get a written line-item quote with the Miami-Dade NOA number for each window, so there’s no question about what you’re buying.
Florida Pays You Back
The incentives stack, and Three Lakes homeowners should understand them before they buy. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades on your primary residence. Florida also suspends sales tax on impact-resistant windows and doors. The federal 25C energy credit returns 30% of the product cost, up to $600 per year, on qualifying Energy-Efficient Windows - Three Lakes units. Then there’s the windstorm premium credit: after a wind mitigation inspection (usually $75 to $150), many carriers cut the windstorm portion of your premium by around 25%. Programs change, and your carrier sets the final numbers, so we’ll point you to the current forms rather than promise a refund amount.
Here’s the direct comparison our Three Lakes customers ask about most: impact windows vs hurricane shutters. Shutters cost less up front, but someone has to pull them out, carry them, and hang them before every storm. Impact windows are in place permanently. You don’t panel up at 11 p.m. in wind. And when an insurer requires NOA glazing, shutters don’t satisfy that requirement. Impact windows do.

FAQs - Window Installation in Three Lakes
Three Lakes requires Miami-Dade NOA. The entire community is inside the HVHZ, and a Florida Product Approval from another county is not a substitute. If an installer hangs a window without a current Miami-Dade NOA, the county can flag the inspection and your insurer can reject the wind mitigation credit. Always ask for the specific NOA number for the unit being installed. Call (727) 620-6983 and we’ll walk you through what compliance documentation should look like before you sign anything.
Shutters are a wind-mitigation device, but Miami-Dade NOA impact glazing is a building product standard. More South Florida carriers now underwrite renewal on the basis of documented NOA windows, not shutter presence alone. An old wind mitigation report might satisfy a past underwriter, but the current one can require active NOA glazing as a renewal condition. If you’ve received a nonrenewal letter, we can help you scope the replacement and document the large-missile rating after install. Call (727) 620-6983 for an exact quote; estimates are free.
Yes, they can. If you’re planning to enlarge an opening or add a sunroom with a garden window, the new opening has to sit clear of your septic drain field and well. Moving a window because it’s too close to the septic line means tearing into concrete block, pulling new permits, and paying twice. We pull the property survey and check setbacks before we hand you a quote, not after the county flags the drawing. Call (727) 620-6983 and we’ll schedule a measure on your property.
Our installation crews can complete a full replacement in as fast as a single day once your units arrive. Custom fabrication typically runs 4 to 6 weeks, and then we schedule the install. On a Three Lakes CBS ranch, the masonry anchoring and seal work is methodical, not rushed. Call (727) 620-6983 and we’ll give you an honest timeline based on your specific product and opening count.
Yes. Our coverage is transferable and includes accidental and hurricane glass breakage, delamination, and labor and materials. The coverage terms don’t change based on your address, and we don’t shorten them for HVHZ work. Call (727) 620-6983 if you want to talk through the coverage specifics before you buy.
Upfront pricing. No surprises on the invoice. If you’re in Three Lakes and ready to stop patching original single-pane aluminum, call (727) 620-6983 to schedule your free estimate. Ed Winslow’s name is on the door and on every window we hang. The one down the road.
