Key Takeaways:

• Monroe County effectively mandates impact-rated doors on permitted structures; touching a jalousie window or door during a remodel can trigger a full replacement requirement.
• Marathon’s salt air corrodes standard aluminum door frames and hardware in 5-7 years. Marine-grade finishes and stainless hardware are not optional here.
• Most Marathon door installs involve hidden framing repair once the old jamb comes off. We price it honestly and get written approval before touching it.
• Every TruePane job carries the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing before our truck leaves your driveway.
• A live person answers our phone 24/7. No voicemail tree, no callback form.

Why TruePane Windows & Doors Is Marathon’s Preferred Door Installation Company

We’re a second-generation glazier company, founded by Dale Kessler, and we’ve spent years doing windows and doors the way a craftsman should: measure twice, quote on paper, register warranties in writing, and stand behind the work. Marathon homeowners call us because they’ve been burned before by mainland outfits that quote a door, then discover the jamb is rotted and the price changes. That doesn’t happen with us, because we already know what Marathon door openings look like.

Our technicians work in elevated CBS homes off Sombrero Beach Road and wood-frame houses on pilings near Boot Key the same way they’d work in their own mother’s house. We carry marine-grade flashing, stainless hinges, and subsill material on the truck because we know salt spray from the Atlantic and the Gulf hits Marathon from both sides. Dispatch and scheduling run from our South Florida office, but the crews who show up in Marathon know the Keys. A live person answers the phone around the clock, and when you call about a door that won’t close or a hinge that’s seized, you get a straight answer, not a script.

Dale Kessler’s founding rule still governs every install: if the pane is not true, the job is not done. We apply that to doors too. Whether it’s a single entry door on a 1950s block home or a full set of impact-rated French doors on a post-Irma rebuild, the standard is the same. Done right, documented, and guaranteed.

Our Door Installation Services in Marathon

Entry & Swing Doors

Entry doors in Marathon take abuse that mainland doors never see. Salt spray, wind-driven rain, and relentless humidity eat standard aluminum frames and hinges in under seven years. We install impact-rated fiberglass and steel entry doors with fusion-welded frames, stainless steel hinges, and marine-grade weatherstripping. Every opening gets measured twice, and if the rough opening is out of square or the jamb is compromised, we address it before the new door goes in. The result is a door that seals tight against tropical storms and doesn’t bind in July.

Storm Doors

A storm door in Marathon is not decoration. It’s a sacrificial layer that takes the brunt of salt spray and wind before it reaches your primary door. We install storm doors with corrosion-resistant frames and tempered or impact-rated glass, depending on the opening and the homeowner’s goals. On elevated homes where wind-driven rain tracks across the porch, a properly flashed storm door keeps the sill pan dry and the subfloor intact. We’ve replaced too many rotted rim joists beneath entry doors to treat storm doors as an afterthought.

Double & French Doors

Double and French doors are common in Marathon’s post-Irma rebuilds and elevated homes where owners want Gulf views and cross-breeze. They’re also one of the most common failure points when installed by a crew that doesn’t understand coastal wind loads. Both panels must seat square against the astragal, the sill must be flashed for wind-driven rain, and the hardware must be stainless or it will seize. We set double doors so both panels close true, shift evenly with humidity, and keep water on the outside where it belongs.

Bifold & Folding Doors

Bifold and folding door systems open whole walls, which makes them attractive to Marathon homeowners building or renovating for indoor-outdoor living. They also carry enormous wind-load requirements in Monroe County. The track, the rollers, the locking points, and the flashing all have to be rated for a direct-hit storm zone. We quote manufacturer lines side by side on paper, including PGT and CGI, so you see exactly what you’re buying and what the warranty covers. Our team handles the structural requirements so the inspection passes the first time.

Pivot Doors

Pivot doors are heavier, larger, and more unforgiving than conventional hinged doors. In Marathon, where humidity swells wood and salt air corrodes pivot hardware, they demand precise installation. We set pivot doors with marine-grade hardware, proper clearance for seasonal movement, and flashing details that keep wind-driven rain from working into the frame. When we install a pivot door, the owner gets a door that opens with one finger and closes true, even in August humidity.

Trusted Brands We Service in Marathon

TruePane is an authorized installer for more than a dozen manufacturer lines, and for Marathon, that matters. We carry and install PGT and CGI impact-rated door lines because they’re engineered for the Florida Keys’ wind zone and salt exposure. We also work with Ply Gem and other manufacturers where a non-impact or standard-rated door is appropriate for an interior opening or a non-permitted application. Our side-by-side quotes on paper show you the price difference between a mainland-grade door and a Keys-grade door before you spend a dollar. That’s a square deal, and it’s the only way we do business.

Common Door Installation Problems We See in Marathon Homes

• Salt-corroded jambs and hinges: Aluminum door frames in Marathon’s salt air corrode to the point of hinge seizure within 5-7 years. When we open these up, the jamb is often too far gone to reuse, and the rough opening needs framing repair.
• Failed sill pans on elevated homes: Older Marathon homes on pilings often have sill pans that were never properly flashed. Years of wind-driven rain wick past the sill, rot the rim joist and subfloor beneath the entry door, and the damage stays hidden until the jamb comes off for a permitted remodel.
• Impact doors with mainland-grade hardware: We see impact-rated doors installed with galvanized hinges and standard weatherstripping. Within two seasons, the hardware seizes or the seal fails, and the door leaks during a tropical storm. Stainless hardware and marine-grade weatherstripping are not upgrades in Marathon; they’re the baseline.
• Jalousie-triggered code requirements: The moment a homeowner pulls a permit for almost any renovation in Marathon, Monroe County inspectors flag original jalousie windows and non-impact doors for mandatory impact-rated replacement. That changes the scope and the budget, and we write it into the contract from the start so there are no surprises at inspection.

When our crew opened up a 1960s concrete-block home off Sombrero Beach Road to replace a corroded aluminum entry door, we found the jamb and rough opening had been saturated by years of salt spray that wicked past a failed sill pan. The wood framing was so compromised it couldn’t hold a standard anchor. We cut back the rotted sections, installed a marine-grade stainless steel subsill and flashing tape, then set a new impact-rated fiberglass door with fusion-welded frame and stainless hardware. That’s the same assembly we’d use in a direct-hit storm zone, because Marathon’s humidity and salt air eat standard door materials in under five years.
