Fast, Reliable Impact Windows & Doors Across Duck Key
If you own a home in Duck Key, every window and door replacement on this island is an impact job. Monroe County code requires it, and the open saltwater on all sides of the island means anything less than marine-grade hardware fails within two or three years. TruePane Windows & Doors has done this work on Duck Key long enough to know exactly what those conditions do to a standard frame, a standard hinge, a standard flashing job. Call (954) 280-4413 and you will speak to a live person, not a call center, who can schedule a free estimate at your place on Duck Key.
The challenge on Duck Key isn’t finding someone to install impact glazing. It’s finding someone who understands that the salt air here eats standard extrusions, that FEMA elevation rules change door specs on stilt homes, and that absentee owners need a company that registers both warranty layers in writing before the truck leaves. That’s the work we do.
Why TruePane Windows & Doors Is Duck Key’s Preferred Impact Windows & Doors Company
Duck Key is a small island, and word travels fast. Homeowners near the Hawks Cay Resort corridor and along the canals have called us for years because they see our crews showing up in uniform, measuring twice, and finishing the job the same day whenever the scope allows. Our work on Duck Key includes replacing salt-eaten Andersen sliders on stilt homes, re-hanging custom-height entry doors on elevated concrete-block houses, and pulling fogged insulated glass units that failed because non-marine hardware gave out. We know what to look for before the truck arrives.
We stand behind the work with The Keystone Standard. Both manufacturer warranty layers are registered in writing, with durations stated, before our crew leaves the driveway. Then we add our Done Right Promise: if the install isn’t right, we make it right. No paperwork fights. No arguing. That matters on Duck Key, where many homes sit vacant for months and a bad install can go unnoticed until a storm is moving in.
Dale Kessler founded this company in 2008 with a rule that still governs every job: if the pane is not true, the job is not done. Our technicians are background-checked and trained to work in a customer’s home the way they’d work in their own mother’s. For Duck Key, that includes understanding marine-grade specs, FEMA elevation basics, and the wind speeds this section of Monroe County actually sees.
Our Impact Windows & Doors Services in Duck Key
Hurricane Impact Windows
Every window replacement on Duck Key is a hurricane impact window replacement. Monroe County’s mandatory impact zone rules leaving no option for standard glazing here. Our Impact Windows & Doors team installs and replaces PG, PGT, and CGI lines with marine-grade frames and stainless or powder-coated hardware rated for the 150 mph-plus design wind speeds in this part of the Keys. We quote side-by-side on paper so you see exactly which product you are buying and what it costs.

Impact Entry & French Doors
Duck Key’s elevated stilt homes rarely accept a standard-height impact door. FEMA flood-zone elevation requirements mean custom-height door units and non-standard sill flashing are the default here, not the exception. We measure every opening twice, order the correct unit the first time, and flash the sill to keep saltwater and storm water out. A square deal, in writing, before any material is ordered.

Impact Sliding Glass Doors
Sliders take the worst of Duck Key’s salt-laden wind. The track, the rollers, the glazing seal. We replace them with marine-grade units, and we specify hardware that won’t seize up from constant salt exposure. If you have a slider that’s hard to open, fogged between the panes, or the exterior frame is oxidizing, that impact rating may already be compromised. We’ll tell you straight what needs replacing and what doesn’t.

Impact Garage Doors
Many Duck Key homes store vehicles, boats, and golf carts in ground-level garages that are fully exposed to wind and salt. Impact-rated garage doors have to carry a heavier wind load than window units, and the track hardware has to survive constant corrosion. We handle the full replacement, including reinforced tracks and marine-grade fasteners, so the door doesn’t blow in during a storm.
We also do Impact Windows & Doors in Duck Key work that includes hurricane shutters and wind mitigation inspections for homeowners who need documentation for insurance or a sale.

Trusted Brands We Service in Duck Key
We’re an authorized installer for more than a dozen manufacturer lines, and on Duck Key we work most often with PGT, CGI, and Ply Gem because those product families hold up to salt and wind better than most. We keep common replacement hardware and seal components on hand for Duck Key customers, so if you call about a failed weatherstrip or a seized roller, the fix usually doesn’t wait on a part from a mainland warehouse. We stand behind every brand we install, and both warranty layers get registered in writing before we leave.
Common Impact Windows & Doors Problems We See in Duck Key Homes
- Ghost corrosion from absentee ownership. Properties that sit empty for a season or more develop frame oxidation and weatherstripping failure that’s invisible from inside. The unit looks fine, but the exterior impact rating is already gone. We catch this during routine service and replacement estimates.
- Non-marine hardware failing in two to three years. Standard aluminum extrusions and zinc-plated hardware don’t survive Duck Key’s constant salt spray. Seals fail, insulated glass fogs, and the frame starts pitting. We spec anodized or powder-coated marine hardware on every job, no exceptions.
- Standard-height doors violating FEMA elevation rules. Elevated stilt homes need custom-height impact doors with non-standard sill flashing. A stock unit won’t pass a wind mitigation inspection and can leak at the sill after one storm season.
- Rollers and tracks seizing on sliding doors. Salt works its way into the track and roller bearings fast on this island. Once the roller binds, the panel gets forced, the frame flexes, and the seal breaks. We see it on bayside and ocean-side properties alike.
Pricing for Impact Windows & Doors in Duck Key, FL
On Duck Key, a typical hurricane impact window runs $900 to $2,400 per opening installed, depending on size, frame material, and the manufacturer line. Impact entry and French doors on elevated homes generally run $4,800 to $11,000 installed because the custom-height FEMA requirement and custom sill flashing add real cost. Impact sliding glass doors run $3,500 to $9,500 installed, and impact garage doors run $5,000 to $14,000 depending on width and reinforcement needs. These are honest ranges for the Duck Key market, not teaser numbers. We quote fixed prices in writing before ordering, and once the price is set, it doesn’t change.

FAQs - Impact Windows & Doors in Duck Key
Duck Key’s code requirements and FEMA elevation rules push most orders into custom sizing and non-standard flashing, and manufacturers build those units to order, not from stock. Lead times typically run six to twelve weeks once the opening measurements are confirmed. Labor on-site is usually one to three days for a typical opening. Call (954) 280-4413 and we’ll map out the schedule before you commit to anything.
Yes. Duck Key sits fully exposed in the open-water Middle Keys with no inland buffer, and Monroe County places every structure in a mandatory impact-resistant window and door zone. Unlike some mainland coastal markets where impact glass is optional, here it applies to all replacements, not just new construction. We pull permits and pass wind mitigation inspections for Duck Key jobs as standard practice, and if you need documentation for insurance, we provide it.
Frames and hardware built from plain anodized aluminum or standard zinc-plated steel can show visible pitting within twelve to eighteen months and fail within two to three years. Duck Key is surrounded by saltwater on all sides, with Atlantic exposure to the east and Florida Bay to the west, and the near-constant salt-laden wind eats through non-marine-grade extrusions and hardware fast. That’s why we spec marine-grade anodized or powder-coated frames and stainless hardware on every Duck Key job.
Ghost corrosion is what happens when an absentee owner misses salt-driven frame oxidation and failed weatherstripping for an entire season or longer. The unit looks fine from inside, but the exterior frame and hardware have already lost enough integrity that the impact rating is compromised. We’ve found it on properties near Hawks Cay and on canal homes where the owners only visit a few weeks a year. A routine inspection catches it before a storm does.
Yes. We replace and install windows and doors on Duck Key homes that were built with custom millwork, specialty glass, and non-standard opening sizes, and we coordinate with designers and architects when the job calls for it. We’ve matched existing trim profiles on luxury stilt homes and spec’d glass that matches the original sightlines. The key is getting the measurements and the manufacturer order right the first time, because custom units can’t be returned if the spec is wrong. Call (954) 280-4413 and we’ll walk your property and take the measurements.
Duck Key’s open-water exposure and FEMA flood-zone elevation requirements change the product spec, the lead time, and the failure patterns for impact windows and doors. Standard mainland assumptions don’t hold here. We price it honestly, order it correctly, and register both warranty layers in writing before the truck leaves your driveway. If you have questions about your current windows or a plan to replace them, call TruePane at (954) 280-4413. A live person answers, and the estimate is free.
