Fast, Reliable Impact Windows & Doors Across Duck Key
Impact windows and doors in Duck Key are not an upgrade. They are the code. Sitting at Mile Marker 61 with open water on all sides, every replacement opening on this island must carry a Miami-Dade Notice of Acceptance, and most of the original aluminum jalousie and single-pane sliders from the 1960s and 1970s no longer pass Monroe County inspection. We know Duck Key because we work it regularly: canal-front concrete-block homes near Hawks Cay, elevated stilt houses on Tom’s Harbor, and vacation properties that sit empty for months while salt spray works on the frames. Call (813) 320-9346 and a live person answers, any hour, any day.
Why TruePane Windows & Doors Is Duck Key’s Preferred Impact Windows & Doors Company
We are not the cheapest bid on Duck Key, and we do not pretend to be. What we offer is a fixed price in writing before ordering, both manufacturer warranty layers registered before the truck leaves your driveway, and a 90-Day Done Right Promise that has no fine print. Dale Kessler founded TruePane in 2008 on a rule that still names the company: if the pane is not true, the job is not done. That standard governs every Impact Windows & Doors install we run from Ocean Drive to Indies Road.
Duck Key homeowners call us after a bad experience elsewhere: a fogged seal that went unaddressed, a slider that bound in July, a warranty that evaporated when the installer stopped answering the phone. We answer the phone. A live person, 24 hours a day, 7 days a week. Our technicians are background-checked, uniformed, and trained to treat your canal-front home the way they would treat their own mother’s. We serve Duck Key from our Miami metro scheduling office, and crews are dispatched locally so you are not waiting on a callback from a regional call center.
Our Impact Windows & Doors Services in Duck Key
The service area for this page is Duck Key, and the work below reflects what we actually see on this island: salt-driven frame corrosion, non-compliant jalousie windows, and homeowners who want the HVHZ paperwork handled correctly the first time.
Hurricane Impact Windows
On Duck Key, replacement impact windows carry a legal requirement, not a preference. Monroe County enforces High-Velocity Hurricane Zone product approval on every permitted opening, which means a Miami-Dade NOA is mandatory for every unit we set. We install impact-rated single-hung, double-hung, casement, and picture windows with laminated glass rated for the Atlantic hurricane track. On a canal-front concrete-block home near Tom’s Harbor, we removed original single-pane aluminum sliders that had been salt-corroded for years while the owners were away and replaced them with fusion-welded vinyl double-hung units featuring low-E glass and argon fill. The NOA paperwork was coordinated so the Monroe County inspection passed without delay. That is standard procedure for us on Duck Key, not an add-on line item.

Impact Sliding Glass Doors
Canal-front homes on Duck Key live and die by their sliders. The original aluminum frames from the 1960s and 1970s corrode from salt spray off both the Atlantic and Florida Bay, and the rollers bind long before the glass fails. We replace them with impact-rated sliding doors that meet current HVHZ code and operate smoothly in the salt environment. If your slider sticks, grinds, or no longer seals against wind-driven rain, that is a structural issue on this island, not a minor annoyance.

Impact Entry & French Doors
Front doors on Duck Key take the brunt of direct ocean exposure. A non-impact entry door in this wind zone is an opening waiting to fail during a storm, and Monroe County inspectors will flag it the moment a permit is pulled for any adjacent work. We install impact-rated entry and French doors with multi-point locking hardware, reinforced frames, and laminated glass rated for the HVHZ. The price is fixed in writing before ordering, so there are no change orders when the lead time stretches.

Impact Garage Doors
Garage doors on elevated Duck Key homes are a weak point that homeowners often overlook until a wind mitigation inspection flags them. A non-rated garage door will fail under positive and negative pressure during a hurricane, which pressurizes the entire structure. We install Miami-Dade-approved impact garage doors with reinforced tracks and bracing that pass Monroe County wind mitigation requirements. If you are pulling a permit anywhere on the home, expect the inspector to ask about the garage door.

Trusted Brands We Service in Duck Key
We are an authorized installer for more than a dozen manufacturer lines, and on Duck Key that matters because the NOA paperwork has to match the product exactly. We quote Andersen, PGT, and ES Windows side by side on paper so you see the glass, the frame, the rating, and the price before you commit. other specialty lines are available for high-end retrofits along the Hawks Cay Resort corridor where architects call for specific performance numbers. We stock common parts for Duck Key jobs locally, so repairs and replacements do not wait on a shipment from the mainland when the part is already on the island.
Common Impact Windows & Doors Problems We See in Duck Key Homes
- Salt-driven frame corrosion: Duck Key receives salt spray from the Atlantic and Florida Bay simultaneously, which oxidizes aluminum frames and eats steel rollers and hinges faster than even nearby mainland-adjacent Keys communities. Homes that sit vacant for months between owner visits fail long before anyone notices.
- Fogged insulated glass from seal failure: The original sliders on many Duck Key homes lose their argon fill when the seal fails, and the fog between panes often goes unnoticed until owners return for season. The glass looks intact but the insulation value is gone.
- Non-compliant aluminum jalousie windows: The breezy lower-level jalousies on older canal-front homes are classic Keys style and now flatly illegal to reinstall under Monroe County HVHZ rules. A single door replacement can trigger a whole-house window conversation that out-of-state owners are rarely prepared for.
- Binding sliders and French doors: Salt and humidity cause steel rollers to seize and wood frames to swell, so doors that opened fine in January bind hard by June. On Duck Key, a door that will not close and seal is a code and insurance problem, not just a nuisance.
Pricing for Impact Windows & Doors in Duck Key, FL
A typical impact window retrofit on Duck Key runs $900 to $2,400 per opening, installed, depending on the size, frame material, and glass package.

Impact entry doors start around $2,200 and run to $6,000 for custom French units with side lites. Garage doors rated for HVHZ typically run $2,800 to $6,500.

FAQs - Impact Windows & Doors in Duck Key
Because Duck Key sits inside Monroe County’s High-Velocity Hurricane Zone, and county inspectors enforce HVHZ product approval on every permitted opening. The Miami-Dade NOA certifies that the specific window or door model has been tested and approved for the wind pressures and impact loads expected here. Without it, the inspection fails, the permit closes, and the unit is not code-compliant. We handle the NOA paperwork as part of every Duck Key install, and we register both manufacturer warranty layers in writing before the truck leaves your driveway. Call (813) 320-9346 to have us check whether your proposed unit carries the right NOA.
No. Under current Monroe County code, the moment a permit is pulled for any opening, the existing jalousie windows are no longer compliant and cannot remain. Many Duck Key homeowners learn this the hard way when a simple door replacement turns into a whole-house window conversation. We quote the full scope honestly before work starts, so there are no surprises after the inspector visits. Call (813) 320-9346 and we will help you understand exactly what triggers compliance on your home.
Salt-driven frame and hardware corrosion. Duck Key gets salt spray from the Atlantic and Florida Bay at the same time, and on a seasonal home that sits vacant for months, the aluminum frames and steel rollers corrode before anyone sees the damage. The glass may look fine while the frame no longer seals, the hardware no longer operates, or the laminated interlayer has degraded from humidity. If your impact windows are hard to open, whistle in a storm, or show white oxidation on the frames, call (813) 320-9346 for an assessment.
Lead times, not labor, set the calendar on Duck Key. Custom impact windows from lines like ES Windows, PGT, or Andersen can run 6 to 14 weeks from order to delivery, and on an island with limited receiving and staging, that schedule gets tighter. We order after the contract is signed and the price is fixed in writing. We do not start demolition until the units are staged and ready, so you are not living with open openings while waiting on a shipment. Call (813) 320-9346 early in your planning, and we will map the schedule backward from your target move-in date.
Yes, in two ways. First, the low-E glass and argon fill on modern impact units cut solar heat gain, which lowers cooling load in the Keys climate. Second, the laminated glass and tight frames stop the salt-laden air that accelerates HVAC coil corrosion, so your air handler is not fighting the same moisture and salt burden. On Duck Key, the energy benefit is real, but the bigger benefit is a window that does not fail structurally or operationally from salt exposure. Call (813) 320-9346 for a free estimate and a straight answer on what your specific openings actually need.
