Fast, Reliable Window Replacement Across Key Biscayne

Window replacement in Key Biscayne runs $800-$2,500 per opening for most impact-rated units, with whole-home projects typically landing between $8,000 and $25,000.

We’ve been on this island enough to know that Crandon Boulevard condos and the quiet streets off Harbor Drive each present their own challenges. One is a forty-year-old aluminum frame with salt pitting. The other is a board that wants specific glass tint. We handle both.

Why Winslow Windows & Doors Is Key Biscayne’s Preferred Window Replacement Company

Ed’s name is on the door. That’s not a slogan. When you call (863) 656-0462, a live person answers, and the buck stops with the guy who founded this company in 2011. We’re not a franchise with a rotating crew. The technician who shows up at your Key Biscayne condo or house is background-checked and in uniform, and they work for Ed Winslow directly.

Key Biscayne homeowners deal with a specific headache: their building needs windows that satisfy both the county and the condo board, and those two groups rarely talk to each other. We’ve spent years navigating that two-track approval on this island. Our clients on Crandon Boulevard, in the Towers of Key Biscayne, and along Mashta Drive know we file the permit, prepare the NOA package, and sequence material orders so installation isn’t waiting on a committee vote.

We carry the 36500-Day Done Right Promise on every job. If it’s not done right, we make it right. A century-long standard. That’s the accountability a mainland big-box installer can’t offer someone living on a barrier island where a bad install means salt water inside your wall cavity within a year.

Our Window Replacement Services in Key Biscayne

Full Frame Replacement

Full frame replacement in Key Biscayne means tearing out the entire existing window down to the rough opening, including the frame, sill, and trim. For older condo towers and single-family homes built in the 1960s through 1980s, this is often the only correct fix. The original aluminum frames on Crandon Boulevard are frequently so salt-pitted and corroded that a pocket insert simply can’t anchor properly. We remove everything, inspect the opening for hidden rust or rot, and set a new frame that meets current HVHZ requirements. This service runs $1,200-$2,500 per opening depending on size and floor height.

Insert Window Replacement

When the existing frame is still structurally sound, an insert window slips into the old frame with minimal disruption to stucco, drywall, or interior trim. Some Key Biscayne condo boards prefer inserts because the building’s exterior appearance stays nearly identical. The catch is that inserts only work when the old frame has survived the salt. We’ll tell you honestly if an insert is a fit or if you’re throwing money at a frame that’s already compromised. Inserts typically run $800-$1,500 per window on the island.

Vinyl Replacement Windows

Vinyl makes sense for Key Biscayne homeowners who want a corrosion-proof frame at a moderate price point. Unlike aluminum, vinyl doesn’t oxidize in constant salt spray, and it handles the humidity without pitting or flaking. We install vinyl units with welded corners and multi-chamber construction, and we always size them with the correct design pressure for your specific elevation and exposure. A typical vinyl replacement in Key Biscayne runs $700-$1,400 per opening.

Energy-Efficient Upgrade

Key Biscayne’s tropical sun punishes glass all year. Upgrading to Low-E coated, low-SHGC (solar heat gain coefficient) glass cuts cooling loads in concrete condo towers and single-family homes alike. We specify glass packages tuned to the island’s southern exposure, because what works in Orlando is wrong for Key Biscayne. Energy-efficient upgrades generally add $150-$400 per window over standard glass, and they pair with the federal 25C energy credit. The right glass also keeps your furniture from fading under that relentless Atlantic glare.

Trusted Brands We Service in Key Biscayne

We’re an authorized installer for PGT, CGI, ES Windows, and Therma-Tru, and we stock common hardware and components locally for fast turnaround on Key Biscayne jobs. When a condo board on Key Biscayne wants a specific frame color in ES Windows’ palette, we can quote and order it without waiting on a third party. When a homeowner needs PGT impact casements with marine-grade hardware, we’re already familiar with the exact configurations that pass Miami-Dade review on this island. Ed’s shop is small enough to know the product lines deeply and big enough to have the relationships that move an order along.

Common Window Replacement Problems We See in Key Biscayne Homes

• Salt-pitted aluminum frames with corroded internal steel. The original 1970s aluminum frames on Crandon Boulevard condos develop deep pitting from decades of salt spray. The steel reinforcements inside rust, and brown staining bleeds through the mullions. By the time you see it on the surface, the frame’s structural integrity is already compromised.
• Seized operators and corroded weep hole covers from non-marine hardware. Builders used standard mainland aluminum hardware with plain steel screws. Within eighteen months of salt-air exposure on Key Biscayne, operators seize and weep covers corrode shut. Every replacement we install uses 316 marine-grade stainless hardware, because that’s what survives here.
• Condo board rejection after permit issuance. A product can sail through Miami-Dade HVHZ review and still get rejected by the association because the frame color or glass tint doesn’t match the board’s approved palette. That swap adds two to four weeks and can invalidate the NOA wind-load rating if the replacement isn’t identical. We’ve seen it happen. We sequence our submittals to avoid it.
• Rubber gaskets hardened and cracked far earlier than expected. The constant salt humidity on this barrier island degrades rubber seals faster than on the mainland. Gaskets dry out, crack, and let wind-driven rain into the track. It’s the most common reason a Key Biscayne window that looks fine from the outside is actually leaking into the wall.

What Window Replacement Costs in Key Biscayne

Impact windows in Key Biscayne generally run $800-$1,500 per window installed. Impact single-hung units land between $900 and $1,800. Large or custom openings, including floor-to-ceiling sliders facing the bay, run $2,500-$5,000 each. Whole-home packages typically fall between $8,000 and $25,000 or more, driven by opening count, floor height, and frame material.

What moves the price in Key Biscayne specifically? Wind zone first. The island sits in Miami-Dade’s HVHZ, the strictest wind-load classification in U.S. building codes, and that requires laminated impact glass and stronger frames. Floor height matters too, because higher floors face greater wind pressures. Frame material is the third driver: marine-grade aluminum costs more than vinyl but lasts longer against salt. And condo work adds review time, which adds carrying costs on any materials ordered early. We offer free in-home measuring and a written line-item quote before any work begins. Call (863) 656-0462 to schedule yours.

Florida Pays You Back

Key Biscayne homeowners can stack several incentives on window replacement. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit returns 30% of product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection, which runs $75-$150, most carriers apply a windstorm-premium credit averaging around 25% on the windstorm portion of the policy. No guarantees, programs and carriers set the final numbers. But the stack is real, and we’ll help you document what qualifies.

The Two-Track Approval: Why Key Biscayne Is Different

Every window replacement in a Key Biscayne condo triggers two approvals that mainland Miami jobs never face. The first is the Miami-Dade permit from the Building Department, which requires a Miami-Dade Notice of Acceptance (NOA) for every window configuration. That alone is stricter than the rest of Florida. The second is written condo association approval, and here’s what makes the island unique: most associations mandate exact frame colors and glass tint levels to preserve the building’s uniform street-facing appearance. A PGT or CGI product can pass HVHZ code perfectly and still get rejected by the HOA board because the tint reads too dark or the frame is one shade off the approved palette. That rejection typically adds two to four weeks to the calendar, and it can force a product swap that jeopardizes the original NOA wind-load rating if the replacement unit isn’t identical to what the permit application described.

We’ve learned to front-load that process. We identify the board’s approved specifications before we finalize the product order. We prepare the full submittal packet, including NOA documentation and sample frame chips, and we file it with both the county and the association at the same time. Then we sequence material ordering so the windows arrive around the same time the board signs off. The goal is that your home is never left open to salt spray while a committee deliberates, and your project doesn’t stall waiting on a second approval that we saw coming.

Recently we replaced original 1970s aluminum single-pane windows in an oceanfront condo on Crandon Boulevard. The aluminum frames had deep pitting from decades of salt spray, and the steel reinforcements inside were rusting. Visible corrosion was bleeding through the mullions. Working with the association’s approved color palette, we installed PGT impact-rated casement windows with laminated glass interlayers and marine-grade stainless steel hardware. The project required two rounds of board review before installation started. We sequenced the permit application and material order so there was no downtime waiting on the committee. The windows went in on schedule, and the opening was never exposed to the elements.

Architectural Review: What Gets Approved on the Island

Key Biscayne’s condo associations accept a narrower range of materials, colors, and styles than any mainland building we work in. Most boards specify white, bronze, or a specific beige-tone frame, with glass tints that read neutral gray or light bronze. Mirrored finishes usually get kicked back. Dark tints often fail, because they shift the building’s appearance from the street. Vinyl frames occasionally face resistance in concrete towers, where boards want metal to match the original structure. Every submittal needs the NOA documentation, a physical frame chip sample, and specification sheets for the exact glass package proposed. We prepare all of it. We file it. And we attend the board review if you want us there.

Review typically adds two to three weeks to a Key Biscayne project timeline, sometimes more if a board meets monthly. We schedule around that. Materials get ordered once we know what’s approved, not before. That’s how we avoid the classic island failure mode where a homeowner buys windows, the board rejects the tint, and the units sit in a warehouse losing their return window.

Impact windows vs. hurricane shutters: Shutters need someone home to deploy them, and they only protect against wind and impact while they’re up. Impact windows protect permanently. No panels to hang, no storage locker to figure out, no nothing. For Key Biscayne homeowners who evacuate or travel during storm season, impact windows are the only option that offers protection when nobody’s around to close the shutters. Many insurers on the island also offer better windstorm credits for permanent impact glass than for shutter systems.

Window Maintenance & Care on a Barrier Island

In Key Biscayne, window maintenance isn’t optional. It’s survival. Salt-laden air lands on tracks, weep holes, hinges, and hardware every single day, from the bay side and the ocean side. We recommend an annual inspection and cleaning of tracks and weep holes, a twice-yearly rinse of the exterior glass with fresh water to knock off salt film, and immediate replacement of any gasket that shows cracking or hardness. We handle all of that as a service, because we know the salt on this island works faster than anywhere in Miami-Dade. A weep hole blocked with salt crust turns into a track that holds water, which turns into corrosion, which turns into a replacement job that could have been a $40 fix.
