Fast, Reliable Window Replacement Across Three Lakes
Window replacement in Three Lakes means something specific: every permitted job must carry a Miami-Dade Notice of Acceptance because this entire community sits inside the High-Velocity Hurricane Zone. That single fact shapes everything about how we approach a project here, from the products we recommend to the way we pull permits. Winslow Windows & Doors has been installing impact-rated windows and doors since 2011, and our crews work throughout Three Lakes regularly. When you call (904) 478-8983, you’ll get a live person who understands the difference between a jalousie window that needs full demolition and an insert that can slide into an existing frame. We’re the one down the road, and Ed Winslow’s name is on the door, and on every job we do.
Why Winslow Windows & Doors Is Three Lakes’s Preferred Window Replacement Company
Three Lakes homeowners tend to do their research before signing anything. They’ve lived through enough hurricane seasons to know that a window is only as good as its product approval number. That’s why our local reputation here is built on paperwork as much as workmanship. We present Miami-Dade NOA documentation before we quote, so you know the product you’re paying for will pass inspection the first time. Our customers in Three Lakes frequently tell us the thing they appreciated most was knowing every surprise gets priced in writing before we touch a single jamb. That’s a direct result of Ed Winslow running an owner-operated company. No ticket numbers, no call centers, and no vague verbal promises.
We’ve replaced windows and doors in Three Lakes homes along SW 137th Avenue, near the residential stretches off SW 128th Street, and throughout the blocks between Killian Parkway and Coral Reef Drive. We know this housing stock well. Most of it is single-story concrete block from the 1970s through early 1990s, and most of it still has the original aluminum single-pane windows that were legal then and are non-compliant now. That experience means our response time to Three Lakes is straightforward: we schedule within days of your estimate, and we don’t send a salesperson who’s never touched a hurricane-rated mullion. Background-checked, uniformed technicians handle every job, and a live person answers every call. If we can’t do it right the first time, the Done Right Promise means we come back and make it right.
Our Window Replacement Services in Three Lakes
We handle the full range of Window Replacement work in Three Lakes, but the housing age and HVHZ code requirements here mean full-frame replacement is often the only legal path. That’s not an upsell. It’s what happens when original aluminum frames from 1978 meet 2026 wind-load law.
Full Frame Replacement
Full-frame replacement in Three Lakes means we remove the entire existing window down to the rough opening, inspect the concrete block jambs for hidden corrosion or water damage, rebuild what’s necessary, and install a new impact-rated unit with its own Miami-Dade NOA. We see oxidized aluminum frames hidden behind trim all the time in this area. Salt-laden humidity works its way behind the old caulk, eats the frame, and suddenly a “simple” swap becomes a structural correction. We plan for that. Inspections come first, allowances are written into the contract, and nothing gets touched until you’ve approved a written change order.

Insert Window Replacement
Insert replacement, sometimes called pocket installation, fits a new window into the existing frame. It works when the frame itself is sound, square, and able to support a heavier impact-rated unit. In Three Lakes, that’s the exception rather than the rule for homes built before 1992. We’ll tell you straight if your frame is a candidate. If it is, insert replacement can save on demolition and stucco repair while still delivering an NOA-compliant product. If it isn’t, which is common here, full-frame is the only responsible option.

Vinyl Replacement Windows
Vinyl is a workhorse material for South Florida for one reason: it never oxidizes. Unlike the aluminum frames on original Three Lakes homes, vinyl doesn’t corrode in salt-laden humidity, and it provides solid thermal performance when paired with the right glazing. We install vinyl impact windows from brands like CWS and ECO Window Systems, and every unit we put into a Three Lakes home carries a Miami-Dade NOA. There’s no corner-cutting here. A vinyl impact window with laminated glass is a serious window, and in this wind zone, that’s the minimum.

Energy-Efficient Upgrade
Replacing old single-pane aluminum in Three Lakes with laminated impact glass does two things at once: it meets HVHZ code and it slashes the solar heat gain coming through your south-facing openings. The original windows in these 1970s and 80s homes were built when electricity was cheap and impact requirements didn’t exist. Today, you’re paying for both. Low-E coatings and argon-filled airspaces are standard in the impact packages we specify, and the difference in your cooling load is most noticeable from August through October, when the afternoon sun sits longest on the west side of your block.

Trusted Brands We Service in Three Lakes
We’re an authorized installer for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru. For Three Lakes specifically, we lean heavily on PGT and CGI because both maintain deep catalogs of Miami-Dade NOA approved impact products, which makes permitting and inspection smoother. ES Windows and ECO Window Systems fill the mid-range for homeowners who want an impact-rated but budget-conscious option. We order directly from these manufacturers, which means we can move quickly when a custom size or configuration gets flagged during a replacement. That’s a real advantage when you’re living in a house that was originally framed around jalousie units no modern brand makes anymore.
Common Window Replacement Problems We See in Three Lakes Homes
We’ve seen the same issues repeat across this community for years. None of them surprise us anymore, and all of them have a clear fix.
- Jalousie windows that can’t be saved. Louvered glass slats in secondary bedrooms or entry vestibules were common in 1970s and 80s Three Lakes construction. They have zero impact resistance and no reglazing option. They must come out entirely, and that often means rebuilding the opening to fit a modern casement or single-hung unit.
- Aluminum frame corrosion hidden behind trim. The salt-heavy humidity along this stretch of South Florida works on aluminum like sandpaper. By the time the trim comes off, the frame is often pitted and structurally compromised, which turns an intended insert replacement into a full-frame job.
- Non-compliant windows from past work. We’ve walked into homes where a previous contractor installed a window without a Miami-Dade NOA. It passed visually and failed inspection. The unit had to be removed, the opening corrected, and a compliant product reinstalled, on the homeowner’s dime. It’s an expensive mistake we make sure our customers never repeat.
- Failed waterproofing around original openings. The original sealant on pre-Andrew homes in Three Lakes is decades past its service life. Water has been finding its way behind stucco for years. When we do a full-frame replacement, we repair and re-flash the opening properly, which is something an insert swap can’t address.
What Window Replacement Costs in Three Lakes
Impact windows in Three Lakes generally run $800 to $1,500 per window installed, and that’s our real working range for standard openings in this market. A typical impact single-hung runs $900 to $1,800 depending on size and design pressure requirements. Large or custom openings, including sliders and picture windows, range from $2,500 to $5,000. Whole-home packages for a single-story Three Lakes home typically land between $8,000 and $25,000 or more, driven by opening count, floor height, and the wind zone rating required for your specific location within the HVHZ. Frame material matters too: vinyl is generally the most economical, aluminum thermally broken frames step up in price, and custom architectural shapes always push the quote higher. Your best move is a free in-home measure and written quote. We come out, inspect every opening, check current conditions, and give you a line-item price before you commit to anything. Call (904) 478-8983 to schedule that.
Pricing for Window Replacement in Three Lakes, FL
A typical insert replacement in Three Lakes runs about $500 to $900 per window when the existing frame qualifies, though as we’ve said, pre-Andrew frames rarely do. Full-frame impact replacement is the realistic baseline here, starting around $800 per window for small vinyl units and climbing from there. The factors that actually move your price in Three Lakes are the number of openings, the design pressure rating required for your wall orientation and elevation, whether we find hidden corrosion or water damage once walls are open, and what brand you choose. You’ll get a written, line-item quote before any work starts. No vague allowances, no handshake estimates. And if a surprise shows up mid-project, which happens in older concrete block homes more than anyone likes, you get a priced change order in writing and the final call on whether we proceed. That’s how Ed Winslow has always run this company.
Florida Pays You Back
Three Lakes homeowners have access to several incentive programs that can meaningfully offset the cost of impact windows and doors. My Safe Florida Home matching grants can provide up to $10,000 for qualifying wind-mitigation upgrades, and impact-rated windows and doors are specifically eligible. Florida also exempts impact-resistant windows and doors from sales tax, which is an immediate savings at point of purchase. On the federal side, the 25C energy credit returns 30% of product cost on qualifying energy-efficient units, up to $600 per year. After installation, many Three Lakes homeowners see windstorm-premium credits averaging about 25% off the windstorm portion of their policy once a wind-mitigation inspection documents the new glazing. That inspection typically costs $75 to $150. We can’t guarantee what your insurer will approve or what any program will fund, but we’ll help you with the documentation every step of the way.
How We Handle What Opening Up an Older Three Lakes Home Actually Turns Up
This is the honest part most contractors skip. When we open up a pre-Andrew Three Lakes home, we often find things the homeowner had no way of seeing: outdated and undersized framing around the original jambs, hidden water damage behind stucco, corroded buck anchors, and waterproofing that failed years ago. The permit process then triggers code requirements that didn’t exist when the house was built. That can mean a quote moves. We handle this differently than anyone else. We inspect first. We write realistic allowances into the contract from day one, instead of lowballing to win the job and then piling on change orders. And every single surprise gets photographed, explained in plain English, and priced in writing before we touch it. You approve it or you don’t. The Done Right Promise isn’t just about the final product. It’s about transparency, starting with the first inspection.
Our crew recently replaced a row of jalousie windows in a 1970s concrete block home off SW 137th Avenue with PGT impact-rated casement units. The original aluminum louvers had no design pressure rating at all and could not be brought into HVHZ compliance under any circumstance. We demolished the old jambs, rebuilt the openings to accept full-frame replacements, installed laminated glass interlayers with a large-missile rating, and then documented every bit of the wind mitigation for the homeowner’s insurer. That homeowner didn’t just get new windows. He got a file his insurance company accepted without argument.

FAQs - Window Replacement in Three Lakes
Because Three Lakes sits entirely inside Miami-Dade County’s High-Velocity Hurricane Zone, the most demanding wind-load designation in the country. A Miami-Dade Notice of Acceptance is a product approval that goes beyond the standard Florida Building Code and certifies that a specific window configuration has been tested to survive HVHZ wind pressures and missile impacts. Most national window brands don’t carry NOAs for this zone, which is why local product knowledge matters. Call (904) 478-8983 and we’ll show you the NOA paperwork for every window we recommend before you pay a cent.
No. Jalousie windows cannot be reglazed or upgraded to meet HVHZ impact requirements. They have zero design pressure rating and no structural path to compliance. They must be fully demolished and replaced with an impact-rated, NOA-approved unit. This surprises a lot of Three Lakes homeowners who call expecting a budget reglazing quote, but it’s the law. We’ll walk you through what full-frame replacement means for that opening and give you a clear written price.
Yes, and the effect is measurable. The original single-pane aluminum windows in Three Lakes homes transfer heat directly into your living space, especially on west-facing walls in summer. Impact-rated laminated glass with Low-E coating reflects solar heat and the argon-filled airspace adds thermal resistance. Homeowners routinely report noticeable cooling-bill reductions after full replacement, often the most dramatic change between August and October. The federal 25C credit recognizes this too, covering 30% of product cost on qualifying units.
It means we remove the entire window, including the old frame, down to the rough opening in the concrete block. We inspect and repair the jambs, address any hidden corrosion or water damage, re-flash the opening, and install a new impact-rated unit secured to code. Insert replacement only works if the old frame is still sound, which is rare in pre-1992 Three Lakes housing. Full-frame is what HVHZ compliance usually requires, and we’ll show you photographic evidence of your existing frame’s condition before we make that call.
You verify the Miami-Dade NOA. Every impact window we install in Three Lakes carries a product approval number that corresponds to a tested design pressure rating for your specific opening size, wall height, and wind zone. We match the rating to your home’s requirements and document everything for your building permit and your insurer. Impact windows are also a permanent form of protection, unlike hurricane shutters that require someone to be home to hang panels before a storm. No panels, no storage, no last-minute scramble. Call (904) 478-8983 for a free estimate and we’ll show you the paperwork.
