Fast, Reliable Window Replacement Across Duck Key
Window replacement on Duck Key is a different job than it is anywhere on the mainland. Every opening you replace here must carry a Miami-Dade Notice of Acceptance (NOA) because the island sits inside Monroe County’s High-Velocity Hurricane Zone. That’s code, not a preference. TruePane Windows & Doors works in Duck Key regularly, and we know what the inspectors require before the first pane comes out. If you’re planning replacement windows on a canal-front stilt home or a Hawks Cay-area vacation property, call (813) 320-9346 and we’ll walk the job with you, measure every opening twice, and price it in writing before you commit to anything.
Why TruePane Windows & Doors Is Duck Key’s Preferred Window Replacement Company
We’re not the cheapest bid on Duck Key, and we don’t try to be. We are the company that shows up when we say, does the work once, and registers both warranty layers in writing before the truck leaves your driveway. Dale Kessler founded TruePane in 2008 on a rule he still keeps on the whiteboard: if the pane is not true, the job is not done. That standard governs every install we do from Bimini Drive to the Hawks Cay corridor.
Duck Key homeowners tend to ask harder questions than most, and they should. Many have owned here for decades. They’ve watched salt air eat aluminum frames on homes built in the 1970s. They know what a fogged sealed unit looks like after a season away. When we quote windows on Duck Key, we quote manufacturer lines side by side on paper, show you exactly which product carries which NOA number, and write the price down so it doesn’t move. Our technicians are background-checked, uniformed, and trained to treat your home the way they’d treat their own mother’s. That’s not a slogan. It’s the hiring standard.
We coordinate scheduling and dispatch from our South Florida office, and our crews serve Duck Key locally. A live person answers our phone 24 hours a day, seven days a week. Not a voicemail tree. Not a callback form. A person. When you call about a failed impact window on a rental property that sat empty since April, someone picks up and starts solving the problem.
We also stand behind the work with the 90-Day Done Right Promise. If something isn’t right, we make it right. No paperwork fights. No arguing. That promise is why a significant share of our Duck Key work comes from referrals, homeowners who got burned once and don’t intend to get burned again.
Our Window Replacement Services in Duck Key
Full Frame Replacement
Full frame replacement on Duck Key almost always means pulling an original aluminum jalousie or single-pane slider out of a concrete-block opening and installing a modern impact-rated unit with a fusion-welded frame and new flashing tape. Salt corrosion around the rough opening is common here, and we treat the opening before we set the new frame. On older canal-front homes along streets like Bimini Drive and Seaview Drive, full frame replacement is the only way to meet current Monroe County HVHZ code and get a clean, square install that won’t bind in July humidity.

Insert Window Replacement
Insert replacement works when the existing frame is still structurally sound and square. On Duck Key, that’s rarer than it is inland, because decades of salt spray from both the Atlantic and Florida Bay tends to rot aluminum jambs from the inside out. We’ll tell you honestly whether an insert makes sense or whether you’re better served pulling the whole frame. Most Duck Key insert jobs we do are on newer homes built after the 1990s, where the original frames were powder-coated and still holding. Expect a typical insert window replacement on Duck Key to run $850-$1,400 per opening depending on glass package and frame material.

Storm Window Replacement
On Duck Key, storm window replacement means impact-rated glazing, not the old-school exterior storm panels you’d see up north. A direct hit from an Atlantic hurricane is a real possibility here, and Monroe County code treats every exterior opening as a potential breach point. We install impact windows from manufacturers including Andersen, Pella, Marvin, PGT, CGI, and ES Windows, each with the Miami-Dade NOA documentation on file before the inspector shows up. If you’re replacing storm-damaged glazing after a named storm, call us, and we’ll get you on the schedule fast.

Energy-Efficient Upgrade
Duck Key’s air conditioning runs hard from May through October, and windows that leak air are the single biggest driver of cooling cost in older island homes. Low-E glass with argon fill cuts solar heat gain meaningfully in this climate, and on west-facing exposures over open water, it’s the difference between a living room that holds 74 degrees and one that fights the compressor all afternoon. A typical energy-efficient window upgrade in Duck Key runs $900-$1,600 per opening for impact-rated low-E units, with the higher end reflecting triple-coat glass and premium frame materials. We always show you the manufacturer performance data in writing before you order.

Trusted Brands We Service in Duck Key
TruePane is an authorized installer for more than a dozen manufacturer lines, and on Duck Key we lean heavily on impact-rated product from Andersen, Pella, Marvin, PGT, and CGI. We also work with Simonton StormBreaker Plus for specific HVHZ applications, as we did on a canal-front stilt home on Bimini Drive where the original 1970s jalousies had to go. Because we install these lines regularly in the Keys, we know which products hold up best against salt air and which NOA documentation each one needs. We quote manufacturer lines side by side on paper so you can see exactly what you’re buying and what it costs. No buried line items. No surprises on the bill.
Common Window Replacement Problems We See in Duck Key Homes
- Salt-corroded aluminum frames and frozen hardware. Duck Key gets salt spray from open water on both sides, so aluminum jambs and sash hardware oxidize far faster than even nearby mainland Keys communities see. We routinely replace windows where the crank operator has seized solid and the frame is flaking white powder.
- Fogged sealed units in seasonal homes. Many Duck Key properties sit vacant for months between owner visits. Seal failure in an insulated glass unit goes unnoticed until the owner arrives for the season and finds fog between the panes. By then the argon fill is gone and the unit’s insulating value has collapsed.
- Non-compliant original jalousie windows triggering whole-house retrofits. A single permitted door replacement on a home still carrying original aluminum jalousies forces a whole-house HVHZ window conversation under Monroe County code. Seasonal owners are rarely prepared for the scope or the cost, and we walk them through it plainly.
- Frame rot at the sill on stilt homes. Elevated stilt construction leaves lower-level openings exposed to wind-driven rain and salt spray from below. Sill rot and flashing failure are common, and we replace the flashing tape and treat the opening whenever we pull a frame.
Pricing for Window Replacement in Duck Key, FL
Window replacement pricing on Duck Key runs higher than mainland Florida, and there’s a reason: every unit must carry a Miami-Dade NOA, the product is impact-rated, and the logistics of working on a water-surrounded island add cost. A typical insert replacement on Duck Key runs $850-$1,400 per opening. Full frame replacement runs $1,200-$2,200 per opening depending on size, glass package, and whether we’re working on a stilt home where access is harder. Energy-efficient impact upgrades run $900-$1,600 per opening. Custom architectural glass and specialty finishes, the kind of work we do on Hawks Cay-area and high-end canal-front properties, can run $2,500-$5,000 per opening and up. We price every job in writing before ordering. The number on the written quote is the number on the bill. Call (813) 320-9346 for a free estimate.

FAQs - Window Replacement in Duck Key
Yes. Duck Key sits inside Monroe County’s High-Velocity Hurricane Zone, and every replacement window or door must carry a Miami-Dade Notice of Acceptance. This is a legal code requirement, not a best practice. We pull the NOA documentation for every product we quote and keep it on file for the inspector. If a contractor quotes you windows without mentioning NOA compliance on Duck Key, ask why. Call (813) 320-9346 and we’ll show you the documentation for the exact product we recommend before you sign anything.
Generally no. Under Monroe County HVHZ rules, the moment you pull a permit for a door replacement on a home with original non-compliant jalousies, the inspector will require those windows to come up to current code as well. This catches seasonal owners off guard every year. We coordinate with your architect or designer to phase the work so the whole house gets done correctly and the permit passes the first time. Call (813) 320-9346 and we’ll walk the scope with you honestly before you pull the permit.
Duck Key receives salt spray from both the Atlantic and Florida Bay simultaneously, and because the island is fully water-surrounded, there’s no buffer. Aluminum frame oxidation and steel hardware corrosion happen far faster here than even a few miles inland. We see jamb and sash corrosion that seizes crank operators within a few seasons. On Duck Key we recommend fusion-welded frames and stainless or coated hardware specifically rated for coastal exposure, and we treat every rough opening for corrosion before setting the new frame. Call (813) 320-9346 for specifics on the hardware we specify for island homes.
Fog between the panes means the insulated glass unit’s seal has failed. On Duck Key, this is especially common in seasonal homes because the failure happens gradually while the house sits vacant, and by the time you arrive for the season, the argon fill is gone and the glass has lost most of its insulating value. The fix is replacement of the sealed unit or the entire sash, depending on the frame. We diagnose this on Duck Key properties regularly and can often match the existing frame so you don’t have to replace the whole window. Call (813) 320-9346 and we’ll tell you over the phone whether it’s a unit replacement or a full-frame job.
Our written price includes the complete window unit, the NOA documentation on file for the inspector, new flashing tape, all labor to remove the old window and set the new one, and disposal of the old unit. It also includes both warranty layers registered in writing with durations stated, and our 90-Day Done Right Promise. What it does not include is surprise change orders. We measure every opening twice before we write the quote, and the number we write is the number you pay. Call (813) 320-9346 for a free estimate and a line-item quote you can review on paper.
