Fast, Reliable Custom Windows & Doors Across Duck Key
Custom windows and doors in Duck Key aren’t a cosmetic upgrade. They’re the difference between keeping your insurance policy and losing it. On this island, surrounded on all sides by open saltwater in Monroe County’s extreme wind-load zone, every exterior opening must carry a Florida Product Approval accepted for wind-borne debris regions. Design wind speeds here top 170 mph. We know that because we replace corroded, failed, and non-compliant units on Duck Key every month. Call (754) 238-2201 for a free estimate, and we’ll walk your property with a clipboard, not a sales script.
Why TruePane Windows & Doors Is Duck Key’s Preferred Custom Windows & Doors Company
TruePane has served Monroe County homeowners for years, and the calls we get from Duck Key follow the same pattern: a pre-Irma sliding door that won’t latch flush, an insulated glass unit gone milky from humidity infiltration, hardware seized by salt spray working from both directions. Our background-checked, uniformed technicians measure every opening twice and quote manufacturer lines side by side on paper. That matters on an island where the wrong window choice means an insurer cancels your policy, not just an uncomfortable room.
Duck Key homeowners call us because we register both warranty layers in writing before the truck leaves the driveway. That’s The Keystone Standard, and it’s backed by the Done Right Promise: if it’s not done right, we make it right with no paperwork and no arguing. Dale Kessler founded this company on the rule that if the pane is not true, the job is not done. That rule governs every custom window and door we set on Duck Key.
Our Custom Windows & Doors Services in Duck Key
We install, replace, and service custom windows and doors across Duck Key, working with elevated CBS and wood-frame homes on concrete pilings that face relentless salt spray from multiple sides. Our Custom Windows & Doors team handles the full scope, from design consultation through final inspection.
Custom Shape Windows
Duck Key homes built after Hurricane Irma often feature trapezoids, radius tops, and angled glazing designed to capture water views from odd rooflines. We measure those openings twice, fabricate to exact dimensions, and set the unit so it drains and seals correctly against bidirectional wind-driven rain. A custom shape window that’s off by a quarter inch leaks. We don’t let that happen.

Commercial Storefront Glazing
Duck Key’s small commercial properties, from the marina-facing storefronts to the small offices near the causeway, need glazing that meets Florida Product Approval for wind-borne debris. We install and replace impact-rated storefront systems, working around the salt corrosion that eats standard aluminum framing within six or seven years here. Business owners get the same written warranty registration as our residential clients.

Curtain Wall Systems
Large water-view expanses on Duck Key demand curtain wall systems engineered for 170 mph-plus wind loads and salt exposure from both the Gulf and the Atlantic. We coordinate with architects and structural engineers on every curtain wall job, because the connections, drainage, and expansion joints determine whether the system performs for twenty years or fails in five. Lead times run 12 to 16 weeks on these systems, so we lock pricing in writing before ordering.

Architectural Grilles & SDLs
Simulated divided lites and architectural grilles aren’t decoration on Duck Key. They’re part of the character of the island’s better homes, and matching existing millwork profiles matters. We source grille patterns from the same manufacturer lines we specify for the glass, and our shop matches the bar width, profile, and finish so a replacement window disappears into the elevation. On Harbour Cay Drive, our crew replaced a pre-Irma 12-foot sliding glass door where the bottom track had corroded through in three places, the insulated glass unit’s seal had failed so the argon was long gone, and the handle no longer latched flush. We used ViewLux impact-rated glazing in a fusion-welded frame with oversized glass panels, matching the home’s existing architectural grilles, and coordinated with the owner’s insurer to confirm the new Florida Product Approval numbers before ordering.

Trusted Brands We Service in Duck Key
We’re an authorized installer for more than a dozen manufacturer lines, including CGI, PGT, and ES Windows. For island work, these brands matter because their marine-grade finishes and hardware coatings hold up longer against Duck Key’s salt exposure than standard residential lines. We keep a rotating stock of common replacement hardware, rollers, and weatherstripping in our service vehicles so most repair calls on Duck Key finish in a single visit. When you need a full replacement, we quote side by side on paper so you see exactly what you’re buying.
Common Custom Windows & Doors Problems We See in Duck Key Homes
- Corroded bottom tracks and hardware on sliding doors. Bidirectional salt spray from the Gulf and Atlantic attacks the aluminum track, rollers, and latch mechanisms within five to seven years. Rollers seize, doors drag, and latches stop engaging flush, which fails wind mitigation inspections and triggers insurance non-renewals.
- Failed insulated glass units from humidity infiltration. Duck Key’s year-round humidity works into failed edge seals, robbing the argon fill and leaving visible milky-white fog between the panes. Once the fill is gone, U-factor performance collapses and the window no longer meets the energy performance your insurer or code official expects.
- Pre-Irma units flagging on wind mitigation. Sliding glass doors and fixed windows installed before 2017 often lack the documentation or the glazing performance required under current Monroe County codes. Insurers flag these units during inspection and refuse to bind or renew until the openings are brought current.
- Custom millwork mismatch after partial replacements. When one window on an elevation fails and gets replaced with a stock unit, the grille profile, glass tint, and frame finish don’t match the rest of the house. On Duck Key, where elevations are highly visible from the water and the street, that mismatch kills curb value and draws attention every single day.

FAQs - Custom Windows & Doors in Duck Key
The salt attacks from both the Gulf and the Atlantic, so every face of the frame, hardware, and weatherstripping takes a hit from at least one direction. Standard anodized or painted aluminum that lasts 15-plus years in central Florida starts showing critical corrosion, failed seals, and seized hardware within five to seven years on Duck Key. We specify marine-grade finishes and recommend annual hardware inspection and lubrication. Call (754) 238-2201 and we’ll check your existing units for corrosion before you get hit with an insurance inspection.
Duck Key sits in Monroe County’s extreme wind-load zone where design wind speeds exceed 170 mph, so insurers require every exterior opening to carry a Florida Product Approval accepted for wind-borne debris regions. They need the product approval number, the installation permit, and the wind mitigation inspection report. We confirm all Florida Product Approval numbers with your insurer before ordering, and our workmanship and both manufacturer warranty layers are registered in writing before the truck leaves the driveway.
Yes. We match existing grille bar width, profile, finish, and glass tint using the manufacturer lines we already work with, including CGI and ES Windows. When the original millwork came from a manufacturer that’s no longer available, our shop can replicate the profile in a marine-grade alternative that withstands Duck Key’s salt exposure better than the original. Call (754) 238-2201 and bring a photo of the existing elevation to the free estimate.
Lead times, not labor. Custom millwork, specialty glass finishes, and oversized impact-rated panels run 12 to 16 weeks from order to delivery. We lock pricing in writing before the long-lead items ship, so the quote you sign is the price you pay when the job is done. Labor itself is usually one to three days depending on the opening and access. Call (754) 238-2201 and we’ll give you an honest delivery date, not an optimistic one.
Three signs: the door doesn’t latch flush, the insulated glass has gone milky or shows condensation between the panes, and the bottom track is corroded through or the rollers drag. Any of these means the unit has lost its argon fill or structural integrity and will fail wind mitigation inspection. A failed track on a pre-Irma door on Duck Key is almost never worth repairing because the rest of the frame and hardware is on the same corrosion clock. We’ll tell you straight, and our repair over $250 carries $50 off. Call (754) 238-2201 and we’ll inspect it for you.
