Fast, Reliable Door Installation Across Key Largo
Door installation in Key Largo comes down to one hard fact: every unit you hang here has to be impact-rated under the Miami-Dade Notice of Acceptance system, or it will not pass a Monroe County inspection, and your insurer will know. We install entry doors, storm doors, pivot doors, French doors, and custom units the right way on canal-front homes, stilt houses, and concrete block ranches from Ocean Isle Estates to Buccaneer Point. TruePane Windows & Doors has been doing glazing work the right way since 2008, and we quote every Key Largo job with the NOA number printed on paper before we touch a single jamb. Call (813) 320-9346 for a free estimate on your door replacement.
Why TruePane Windows & Doors Is Key Largo’s Preferred Door Installation Company
Key Largo is not mainland Miami. It is a narrow limestone island with the Atlantic on one side and Florida Bay on the other, and every door frame, hinge, and threshold here takes two directions of salt air year-round. Dale Kessler founded TruePane in 2008 as a second-generation glazier who was tired of seeing out-of-true installs and voided warranties, and our crews have worked the Upper Keys long enough to know exactly what a salt-corroded aluminum sill looks like and what it takes to fix it properly. We do not send a different subcontractor every month. Our background-checked, uniformed technicians work in your home the way they would work in their own mother’s.
Key Largo homeowners call us because we quote manufacturer lines side by side on paper, register both warranty layers in writing before the truck leaves the driveway, and stand behind every install with a 90-Day Done Right Promise. That promise is simple: if the work is not right, we return and make it right. No paperwork fights, no arguing. We have been a local company for over four decades through our founder’s glazier lineage, and we sponsor county fairs and church roof funds because we plan to be in town thirty years from now. When you call (813) 320-9346, a live person answers, not a voicemail tree.
Our Door Installation Services in Key Largo
Every door we hang in Key Largo is quoted, ordered, and installed around one requirement: the entire assembly must carry a Miami-Dade NOA impact rating. That means the frame, hardware, anchoring, and glazing all come from the same rated system, not a mix-and-match job that a cheap quote will try to slip past you. Here is what we install most often in Key Largo:
Entry and Swing Doors
Most Key Largo entry doors we replace are original units from the 1960s through the 1980s, and many have steel hardware that has been quietly rusting from dual salt-spray exposure for decades. We install impact-rated swing doors with marine-grade stainless hinges and handles, fusion-welded frames, and anchoring patterns that match the NOA drawings exactly. A proper entry door in Key Largo keeps hurricane wind-driven rain outside and holds its lock alignment through every season.

Storm Doors
A storm door in Key Largo is not the same product people buy in central Florida. Here it is the first line of defense against salt-laden wind and flying debris, so we only install storm doors with Miami-Dade NOA approval and corrosion-resistant frames. On canal-front homes, we see storm doors with steel hardware rusted solid within two years. Our quotes specify marine-grade hardware from the start because replacing a handle in eighteen months is not a repair; it is a design failure.

Pivot Doors
Pivot doors have become popular on Key Largo waterfront remodels, and they are unforgiving to install correctly. A pivot door carries its weight on a top and bottom hinge point, so the rough opening has to be dead plumb and the anchoring has to handle both gravity and hurricane uplift. On a stilt home, where the floor framing moves slightly with temperature and wind, a pivot door needs even more precise shimming and anchoring than a slab-on-grade install. We measure every opening twice and quote the pivot system as a complete assembly, never a slab swap.

Double and French Doors
Double French doors facing Florida Bay look beautiful for about three years if they are hung with mainland-grade hardware and weatherstripping. In Key Largo, the active leaf takes the brunt of salt air every afternoon when the sea breeze picks up, and the passive leaf leaks if the astragal does not seal tight. We install impact-rated French doors with multipoint locking, marine-grade weatherstripping, and sills that shed water away from the threshold. The goal is a door that still opens and locks cleanly ten years after the install, not just for the first season.

That means when your existing Andersen or Pella French door needs a replacement roller, a new multipoint lock, or a fresh sweep, we can usually handle it the same visit without ordering a part from a mainland warehouse. For full replacements, we quote Andersen, Pella, and Marvin side by side on paper so you see the exact numbers, the exact NOA ratings, and the exact warranty durations before you spend a dollar.
Common Door Installation Problems We See in Key Largo Homes
- Corroded original aluminum sliding door frames on canal-front homes. We regularly walk into Ocean Isle Estates and Buccaneer Point homes where the 1970s aluminum frames have pitted and swollen from forty years of dual-side salt exposure. The panels will not lock, and many owners are surprised to learn Monroe County requires a full permitted replacement with an NOA-certified impact unit, not just a glass swap.
- Non-marine-grade hardware on new doors. A stainless hinge is not automatically marine-grade. The cheap stainless used in budget door packages rusts within months in Key Largo’s salt-laden air, and then the lock binds and the owner is calling us anyway. We specify true marine-grade 316 stainless for hinges, handles, and fasteners on every exterior door.
- Stilt home rough openings measured as if the floor is on concrete. FEMA flood zone requirements put thousands of Key Largo homes up on pilings, and the elevated floor systems move differently than a slab. Installers who order standard door sizes and then shim or cut jambs to force a fit are voiding the HVHZ anchoring warranty. We measure elevated rough openings twice and order to the actual dimensions.
- Glass-only impact replacements that leave the old frame in place. The Miami-Dade NOA covers the entire door assembly, not just the insulated impact glass unit. A company that swaps the glass but leaves a 1970s aluminum frame has not done a compliant installation, and the permit will not pass final inspection. We replace the full unit with a rated system, and the NOA number goes on the permit.
Pricing for Door Installation in Key Largo, FL
A typical entry or swing door replacement in Key Largo runs $1,800 to $4,200 depending on the NOA rating, size, and whether the home is on slab or stilt. Storm doors typically land between $900 and $2,400 for impact-rated, marine-grade units. Pivot doors are a different animal: most Key Largo pivot door installs fall between $4,500 and $9,000 because of the precision anchoring, the rated hardware, and the custom sizing most stilt homes require. Double French door replacements on canal-front homes generally run $3,200 to $7,500. The single biggest variable is compliance: a quote that includes the NOA number on the permit, marine-grade hardware, and full perimeter flashing costs more than a glass-only swap, and it is the only quote that will pass a Monroe County inspection. Call (813) 320-9346 for an exact line-item quote. Estimates are free.

FAQs - Door Installation in Key Largo
Yes. Every exterior door in Key Largo requires a Miami-Dade NOA impact rating, regardless of whether the home is canal-front, stilt, or inland concrete block. The entire island sits inside Florida’s High Velocity Hurricane Zone, and there is no interior exemption anywhere in Key Largo. Call (813) 320-9346 if you want us to check the NOA rating on a door you are considering.
No, and if a contractor tells you that is allowed, walk away. Monroe County requires a full permitted replacement of the entire door assembly, including the frame, hardware, and anchoring, all covered by a Miami-Dade NOA. A glass-only swap leaves the non-compliant frame in place and will fail final inspection. The correct fix is a full replacement with a rated system, and we quote that job every week in Key Largo.
Stilt homes move. The elevated floor framing flexes with temperature changes, wind load, and foot traffic, which means rough opening dimensions can shift by a quarter inch or more seasonally. Installers who treat a stilt opening like a slab opening end up shimming and cutting jambs to force a fit, which voids the HVHZ anchoring warranty and makes the door bind within a year. We measure stilt openings twice, order to actual dimensions, and anchor according to the NOA drawings for the specific wall construction.
A documented, permitted, NOA-compliant door installation is evidence your insurer can verify. After a hurricane, the difference between a paid claim and a denied one often comes down to whether the damaged door had a Miami-Dade NOA rating, was installed under permit, and passed inspection. We print the NOA number on the permit application and register both warranty layers in writing, so you have a paper trail that stands up when your adjuster asks for proof of compliance. Call (813) 320-9346 and we will walk you through what that documentation looks like.
A compliant quote includes the Miami-Dade NOA number, marine-grade 316 stainless hardware, full perimeter flashing, anchoring that matches the NOA drawings, a permit line, and both warranty layers registered in writing. A cheap online quote typically prices a door and basic install only, with no NOA documentation, no permit, and mainland-grade hardware that will rust within a year. That cheap quote will not pass a Monroe County inspection, and the redo will cost more than the compliant job would have. Call (813) 320-9346 for a line-item quote that shows you exactly what you are paying for.
