Why Duck Key Homeowners Choose TruePane Windows & Doors
People on this island tend to ask hard questions before they hire. We don’t blame them. A window replacement in Duck Key is rarely a casual upgrade; it’s usually forced by an insurance non-renewal, a failed wind mitigation inspection, or a sliding door that hasn’t latched flush since Irma. Homeowners in neighborhoods like Centre Island and the canal-front streets off Bimini Drive call us because we answer the phone, show up when we say, and put every manufacturer warranty on paper before the truck leaves the driveway.
Our technicians are background-checked and uniformed. They measure every opening twice and bring manufacturer quotes side by side, so you see the difference between a PGT impact window and a CGI unit in writing, not over the phone. The Keystone Standard governs every job: both warranty layers registered, durations stated, and a Done Right Promise behind the work. If the pane is not true, the job is not done. That’s the rule Dale Kessler keeps on the whiteboard, and it’s the reason Duck Key homeowners who’ve been burned once tend to call us first the second time.
Windows & Doors Services We Offer in Duck Key
Window Installation
New construction or post-storm rebuild, we set windows square and seal them for wind loads exceeding 170 mph design speeds. Our installers respect the piling elevations and CBS construction common across Duck Key, because out-of-true installs here don’t just leak; they fail inspection.
Learn more about our Window Installation in Duck Key.

Door Installation
Entry doors, balcony doors, and primary egress doors all get set to close dead flush with weatherstripping that won’t whistle in a September squall. We handle the heavier glass doors and the hardware that seizes up from salt exposure faster than a mainland contractor would believe.

Window Replacement
Most of what we replace in Duck Key are older units with failed seals and frames that can’t pass a wind mitigation inspection anymore. We pull permits, pull the old unit, and set the new one with a written workmanship warranty attached.

Impact Windows & Doors
On this island, impact-rated openings aren’t a luxury line item. They’re the difference between a policy that binds and a letter of non-renewal. We’re an authorized installer for PGT and CGI, and we’ll show you both quotes on paper.

Energy-Efficient Windows
Low-E glass and tight seals matter here, not just for cooling bills but for keeping humidity out of the frame cavities where IGU seals fail. We spec glass packages suited to a house that gets southern exposure over open water.

Sliding & Patio Doors
Those pre-Irma aluminum sliders with the corroded bottom tracks are the most common call we take on Duck Key. We replace the track, the rollers, the seals, or the whole unit, and we’ll tell you honestly which one it needs.

Glass Railing Systems
For elevated decks and pool landings, glass railing has to hold up to wind load and salt spray without loosening. We install systems that pass inspection and stay clear enough to keep the water view you paid for.

Custom Windows & Doors
Water-view picture windows, oversized sliders, odd opening sizes from older raised homes; if it needs a custom cut and a careful set, that’s the work we do. We’ll measure, order, and install to the opening rather than asking you to rebuild the opening to fit a stock unit.

Neighborhoods We Serve in Duck Key
We work throughout the island, from the canal lots off Bimini Drive to the homes along Harbour Drive and the quieter end past Centre Island. Typical response for estimates and service calls in Duck Key is set at the time you call; no waiting on a callback.

Why Duck Key’s Climate & Housing Affect Windows & Doors
Duck Key is not a coastal lot with one side facing the water. The whole island is surrounded by open saltwater, which means window frames, glazing seals, hardware, and weatherstripping get hit by bidirectional salt spray year-round. Aluminum components that last fifteen years in central Florida commonly show critical corrosion and seized hardware within five to seven years here. The residential stock is almost entirely elevated CBS or wood-frame homes on concrete pilings, many rebuilt to post-Hurricane Irma codes with large sliding glass doors and expansive picture windows facing the water. Those openings take wind, spray, and humidity from multiple sides at once. When we replace a window or door here, we spec for that reality, not for a generic Florida climate.
Pricing for Windows & Doors in Duck Key
Impact-rated windows in Duck Key typically run higher than mainland equivalents because the units themselves carry wind-load certifications for the Keys’ 170-plus mph design speeds. Expect a standard impact window replacement to fall in the range of $900 to $1,800 per opening installed, depending on size and manufacturer. Impact sliding glass doors generally land between $2,500 and $6,500 installed. Stock, non-impact replacements run lower, but they often will not satisfy an insurer here. Every quote we write is line-item and fixed; no change orders, no surprise line items. We also offer a permanent 5% discount for seniors and veterans, plus a free written repair estimate. Call (754) 238-2201 for an exact number on your openings.

FAQs About Windows & Doors in Duck Key
Impact window replacement in Duck Key generally costs between $900 and $1,800 per opening installed, depending on size, brand, and whether the opening needs any structural attention. Sliding impact doors run from around $2,500 to $6,500 installed. Every quote is fixed and line-item, so the number we give you is the number you pay. Call (754) 238-2201 for a free estimate.
Usually not. Duck Key sits in Monroe County’s extreme wind-load zone, and insurers in the Keys routinely cancel or refuse to bind policies without verified impact-rated windows and doors. Even if a policy is currently in force, a non-impact unit that fails a wind mitigation inspection can trigger non-renewal. We install Florida Product Approved impact units from PGT and CGI, and we register both warranty layers in writing before we leave.
Most window and door replacement jobs on Duck Key are completed in a single visit once the units are on hand, though custom or oversized water-view units can add lead time at the factory. We pull permits, set the openings, and pass inspection before we consider the job done. We’ll give you a written timeline with your quote.
Yes. The pre-Irma aluminum sliders with corroded bottom tracks and seized hardware are the most common service call we take on Duck Key. Depending on the condition of the frame and the glass, we replace the track, rollers, and seals, or we replace the entire unit if the seals have failed. We’ll show you the difference in writing before you spend a dollar.
No. Our quotes are fixed. What we put on paper as the line-item price is what you pay, with no change orders and no surprise line items on the final bill. If we find something in the opening that needs attention, we stop and show you before any additional work is approved. Call (754) 238-2201 to schedule a free estimate.

What Duck Key Customers Say
"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G.
