AfterFast, Reliable Door Installation Across Key Biscayne
Door installation in Key Biscayne starts with one hard truth: every exterior opening on this island must meet Miami-Dade County’s High Velocity Hurricane Zone code, and it must carry a Notice of Acceptance rating. That’s not a preference. It’s the law, and it’s the first thing we check before we quote anything. TruePane Windows & Doors has installed and replaced doors in Key Biscayne condos along Crandon Boulevard, mid-century homes in the island’s interior, and oceanfront units facing the Atlantic. Call (754) 238-2201 and you’ll reach a live person who can talk you through what your specific opening needs.
We serve all of Key Biscayne, from the 33149 zip code’s southern tip near Cape Florida Light to the village’s northern entry off the Rickenbacker Causeway. Our crews know the island’s housing stock: concrete-block singles built in the 1950s through the 1970s, concrete high-rises along the ocean drive corridor, and the townhome clusters that went up in the 1980s. Each building type has its own door replacement realities, and we’ve worked all of them.
Why TruePane Windows & Doors Is Key Biscayne’s Preferred Door Installation Company
TruePane was founded in 2008 by Dale Kessler, a second-generation glazier who still keeps one rule on the whiteboard: if the pane is not true, the job is not done. That rule governs every door we hang on this island. We’re not a franchise outfit cycling through subcontracted crews. We hire local, train apprentices into journeymen, and background-check every technician who walks into a Key Biscayne home. The men and women on your job dress in uniform, measure every opening twice, and register both manufacturer warranty layers in writing before the truck leaves your driveway.
Key Biscayne homeowners tend to keep their properties for decades. They remember the contractor who left a door that binds in July and a seal that fogged by Christmas. Our Done Right Promise exists for exactly that reason. If something isn’t right, we make it right. No paperwork fights, no fine print, no arguing. We also answer the phone 24 hours a day, seven days a week with a live person. When a salt-corroded hinge fails or a storm door won’t latch after a squall, you don’t want a voicemail tree.
We’re an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. That matters on Key Biscayne because not every manufacturer builds a door that carries the Miami-Dade NOA rating this island requires. We quote manufacturer lines side by side on paper so you can see exactly what you’re paying for and what rating each product meets.
Our Door Installation Services in Key Biscayne
Entry & Swing Doors
An entry door on Key Biscayne does two jobs at once: it’s the first thing a guest sees and the last line of defense against hurricane-force wind and salt-driven rain. We install impact-rated swing doors with marine-grade stainless steel hinges and multi-point locking hardware as standard. On Mason Lane and Fernwood Road homes with original 1960s and 1970s doors, we frequently replace the entire opening rather than retrofit, because the old frame is rarely square and the threshold has usually corroded.
Storm Doors
A storm door in Key Biscayne is a sacrificial layer against the island’s bidirectional salt spray. It takes the brunt of airborne salt that would otherwise eat the finish and weatherstripping off your primary entry door. We install storm doors with fusion-welded frames and corrosion-resistant hardware spec’d for marine exposure. On homes along Harbor Drive where the prevailing easterly wind pushes salt off the Atlantic, we recommend storm doors with the highest salt-spray test ratings in their class.
Arched & Custom Doors
Key Biscayne has a fair number of older homes with arched or radius-topped entry openings, particularly in the village’s mid-century sections. Those openings almost never accept a stock door. We measure, fabricate, and install custom radius doors that carry Miami-Dade NOA ratings just like their rectangular counterparts. The custom lead time runs longer than a standard door, usually four to eight weeks depending on the manufacturer, but the fit is exact and the rating is documented.
Double & French Doors
French doors and double entry doors on Key Biscayne bring a specific failure mode: the inactive leaf’s locking hardware corrodes first, throwing the pair out of alignment and leaving the active leaf to bind. We install double doors with marine-grade hardware at all four locking points and align the inactive leaf so both panels lock and seal evenly. This is a common job in the townhome clusters off Crandon Boulevard where original 1980s double doors are nearing the end of their useful life.

Trusted Brands We Service in Key Biscayne
We install and service doors from Andersen, ES Windows, and ECO Window Systems, among others. Each of these manufacturers builds products that meet the Miami-Dade NOA impact-rating standard this island demands, but they differ in frame construction, hardware grade, and glass package. When we quote a Key Biscayne job, we show the brands side by side on paper with the rating each carries. For service calls on existing doors, we stock common replacement parts for these lines locally, which speeds up repairs on the island considerably. A broken roller or seized hinge on an Andersen slider off Crandon Boulevard does not need to wait for a part to ship from the Midwest.
Common Door Installation Problems We See in Key Biscayne Homes
- Corroded marine hardware on doors less than five years old. Installers without island experience spec standard zinc-plated hinges and lock mechanisms. In Key Biscayne’s salt-saturated air, those parts seize within 18 to 24 months. We spec stainless steel or marine-grade coated hardware on every exterior door, interior lot or not.
- Doors quoted without Miami-Dade NOA ratings. Mainland contractors sometimes price a door that carries a generic Florida Product Approval, not the Miami-Dade Notice of Acceptance this island’s code requires. The failed inspection comes later, followed by removal and a second install. We quote NOA-rated products from the start.
- Upper-floor condo replacements planned without crane access. The older towers along Crandon Boulevard often need custom-sized impact units that cannot fit in a passenger elevator. A proper quote includes the crane, the right-of-way permit, and the scheduling coordination with the village. Contractors who miss this leave openings boarded for weeks.
- Seal failure and fogging from salt-driven glass degradation. The island’s geometry means salt spray hits glass from multiple compass points year-round. That accelerates edge-seal failure in insulated glass units. We replace failed units with marine-spec’d glazing and document the warranty in writing.
Pricing for Door Installation in Key Biscayne, FL
A standard impact-rated entry door replacement in Key Biscayne typically runs $6,500 to $10,500 installed, depending on the door’s size, the manufacturer line, and the condition of the existing rough opening. Sliding glass door replacements run $7,000 to $13,000. Storm doors range from $1,800 to $3,200. Custom radius doors start around $12,000 and climb with size and finish. Upper-floor condo replacements that require a crane typically add $2,500 to $5,000 for the lift and right-of-way permitting. These are real island numbers, not mainland prices with a markup. The salt-air corrosion factor means we quote marine-grade hardware as default, not as an upgrade line item.

| Impact entry door (standard opening) | $6,500 - $10,500 |

FAQs - Door Installation in Key Biscayne
Every exterior door in Key Biscayne must carry a Miami-Dade County Notice of Acceptance, which is a product approval specific to the High Velocity Hurricane Zone. A standard Florida Product Approval covers the rest of the state but does not meet Miami-Dade’s stricter pressure and impact testing standards. Key Biscayne, lying entirely within the HVHZ, requires the NOA. We only quote NOA-rated doors on this island, and we register the documentation so you have it for inspections and insurance records. Call (754) 238-2201 and we’ll walk through the specific rating your opening needs.
Because Key Biscayne is a true oceanic barrier island only about a mile and a half wide, every property on the island receives airborne salt from multiple directions. The bay to the west and the Atlantic to the east both push salt-laden air across the island, and the prevailing easterly winds carry it inland from the ocean. That means a home on West McIntyre Street sees hardware corrosion rates comparable to a direct waterfront property in mainland Miami. We spec stainless steel hinges and multi-point locks on every exterior door here, not just the oceanfront ones. Call (754) 238-2201 for a quote that assumes the salt, no matter your address on the island.
Replacing a pre-Hurricane Andrew sliding glass door with a Miami-Dade NOA-rated impact unit can reduce your windstorm premium, but the insurance carrier needs the right paperwork. You’ll need the Notice of Acceptance document, the installation record showing the door was installed according to the manufacturer’s NOA specifications, and in some cases a final inspection sign-off from the village. We provide all of that in writing at the end of the job. Call (754) 238-2201 and we’ll tell you exactly what documentation you’ll receive before you make a decision.
Two extra steps apply on Crandon Boulevard. First, the village requires a right-of-way permit if the installation requires staging equipment or a crane on the public street, and that permit must be coordinated with the village’s schedule. Second, many of the older towers have condo association rules about unit exterior modifications, and the association typically needs to approve the door’s appearance and rating before the work proceeds. Last month our crew replaced a 1970s sliding glass door in a mid-rise condo along Crandon Boulevard, craned the new Andersen impact unit over the boulevard, and coordinated every permit step with the village office. Call (754) 238-2201 to have us handle the permitting on your building.
Salt from both the bay and the ocean lands on the door’s glass edges and works its way into the edge seal of the insulated glass unit over time, degrading the sealant and allowing moisture inside the airspace. That’s what causes fogging. In mainland Miami, the salt exposure is typically from one direction or absent entirely, so the same edge seal lasts decades. Key Biscayne’s island geometry means the entire perimeter of the building is under constant salt loading. We spec marine-tested glazing and edge-seal systems on island door replacements, and we register the glass warranty in writing so a fogged unit is covered. Call (754) 238-2201 for a free estimate on your door glass replacement.
If you live on Key Biscayne and need a door quoted, installed, or repaired, call (754) 238-2201. You’ll get a live person, a straight answer about what your opening needs, and a written quote that accounts for this island’s salt, wind, and code reality. We’ll be there when we say, and we’ll stand behind the work.
