AfterFast, Reliable Custom Windows & Doors Across Key Biscayne
Custom windows and doors in Key Biscayne are not a cosmetic decision. They are the difference between a home that holds up to salt air and hurricane code, and one that fails inside five years. TruePane Windows & Doors installs, replaces, and services custom openings across the island, from mid-century concrete-block homes off Crandon Boulevard to high-rise condo towers on the ocean side. We spec marine-grade hardware and Miami-Dade NOA-rated glass on every project, because on this island there is no inland. Call (754) 238-2201 for a free estimate, and we will send a technician who measures twice and quotes on paper.
Why TruePane Windows & Doors Is Key Biscayne’s Preferred Custom Windows & Doors Company
We have replaced enough original aluminum sliders in Key Biscayne to know what the salt does to them before we unbolt the first screw. The pillowed frame corners, the white crust in the weep holes, the lock handle that will not turn. Homeowners here do not need a sales pitch. They need a company that registers both manufacturer warranty layers in writing before the truck leaves the driveway, and that is exactly what we do under The Keystone Standard.
Our crews know the village’s permitting rhythm. We know that upper-floor condo replacements along Crandon Boulevard require crane lift coordination, not a ladder and a prayer. We know that the building department reviews every structural opening against the HVHZ code, and we pull permits and schedule inspections without making the homeowner chase paper. Dale Kessler founded this company in 2008 because he kept seeing out-of-true installs and voided warranties destroy good people’s homes. We have spent years as a craft company, not a call center.
Every TruePane technician is background-checked and uniformed. Every quote is line-itemed on paper, side by side across manufacturer lines. And when you call (754) 238-2201, a live person answers, day or night. No voicemail trees, no regional call center, no callback form. If the pane is not true, the job is not done.
Our Custom Windows & Doors Services in Key Biscayne
Key Biscayne’s housing stock runs from 1950s single-family concrete-block homes to 1970s condominium towers to newer builds behind the gates of the Ocean Club. The one constant is salt. Every service below gets spec’d with marine-grade hardware and NOA-rated glass as the starting point, not an upsell.
Custom Shape Windows
Many mid-century homes on Key Biscayne were built with arched, radius, eyebrow, and trapezoid openings that big-box suppliers will not touch. We manufacture and install fully Custom Windows & Doors in Key Biscayne to the exact radius and jamb depth of the original opening, so the window fits the house instead of the house being rebuilt around the window. On this island, we frame custom shapes in powder-coated reinforced aluminum or marine-grade wood-clad systems, because standard mill finish aluminum will pit within five years from bidirectional salt spray.
Oversized Glass Panels
Ocean-facing condominiums and modern single-family homes on Key Biscayne commonly have fixed glass walls and floor-to-ceiling openings that span 8, 10, sometimes 14 feet. These panels must carry a Miami-Dade NOA impact rating AND hold up to constant salt loading. We spec insulated laminated glass units with stainless steel glazing channels and marine-grade setting blocks. We also coordinate the crane lifts and street closures that upper-floor oversized panel replacements on Crandon Boulevard and Ocean Lane Drive require. A mainland contractor who has never worked an island high-rise will underbid that coordination, and the condo board will feel it later.
Architectural Grilles & SDLs
Simulated Divided Lites and true divided lites are common on Key Biscayne residences, especially mid-century houses that want to keep their original sightlines while upgrading to impact glass. We build grilles between the glass where the homeowner wants easy cleaning, or external SDLs where the association’s architectural guidelines require a true muntin profile. On this island, every grille material gets evaluated for salt resistance before it is installed. We do not put plain steel grilles into a Key Biscayne window. They rust, and then the homeowner pays twice.
Commercial Storefront Glazing & Curtain Wall Systems
Condominium lobbies, retail storefronts along Crandon Boulevard, and the commercial buildings near the village center all face the same corrosive environment. We install and service commercial storefront glazing, curtain wall systems, and entrance doors engineered for HVHZ wind loads and salt spray exposure. For older towers on the island, we commonly repair or replace failed curtain wall gaskets, corroded pressure plates, and fogged insulated units in lobbies and amenity spaces. These are not one-day patch jobs. They are measured, fabricated, and installed to keep the building envelope watertight for decades.

Trusted Brands We Service in Key Biscayne
TruePane is an authorized installer for more than a dozen manufacturer lines, including PGT, CGI, and CWS, all of which produce Miami-Dade NOA-rated impact products suited to Key Biscayne’s coastal environment. We keep local stock of common hardware, gaskets, weep covers, and lock components for these lines, which means we are not waiting on a shipment from Texas when a Key Biscayne homeowner’s lock has seized and the door will not secure. We quote manufacturer lines side by side on paper so you can see the cost difference and the performance difference before you sign anything.
Common Custom Windows & Doors Problems We See in Key Biscayne Homes
- Corroded aluminum frames within five years. The bidirectional salt spray on Key Biscayne reaches interior lots, not just waterfront units. Standard mill finish aluminum pits, the jamb warps, and the sash binds, even on the landward side of the island.
- Clogged weep holes from salt crystals and blown sand. When weep holes plug, moisture sits inside the frame, rots the flashing tape, and leaks into the wall around the window. By the time a homeowner sees the water stain, the damage is already inside the rough opening.
- Seized multi-point locking hardware. Non-marine-grade locks crust over from salt air. A door that cannot be locked is a code violation in the High Velocity Hurricane Zone and a security issue any night of the week.
- Fogged insulated glass in 1960s and 1970s openings. The original single-pane glass in older Key Biscayne homes and condos predates post-Hurricane Andrew code. When a seal fails and the glass fogs, the unit usually needs full replacement anyway, because it never met impact standards to begin with.
These failures are not random. They are the direct result of standard-spec materials installed in an environment that never forgives standard-spec materials. When we rebuild an opening on Key Biscayne, we install hot-dip galvanized or stainless steel fasteners, marine-grade butyl flashing tape, and sealed frame corners. The cost difference exists for a reason, and we will show you the line items.
Pricing for Custom Windows & Doors in Key Biscayne, FL
A no-frills replacement of a standard 36-by-60 NOA-rated impact window in Key Biscayne typically runs $900 to $1,600 installed. Custom shape windows start around $1,800 and climb with the arc math, the finish, and the glazing package. Oversized glass panel replacements on upper floors, including crane coordination, commonly run $4,000 to $12,000 depending on the size, the lift window, and the street closure permits. Architectural grilles and SDLs add $40 to $90 per square foot to the base window cost.
Why does the same size window cost more here than in Coral Gables? Because Key Biscayne requires marine-grade hardware, NOA impact ratings, and often crane work. The cheaper inland-spec window will fail on this island inside a decade. Paying for the coastal spec once costs less than replacing the cheap spec twice. We give free written estimates with fixed, line-itemed pricing. No change orders, no surprise line items. Call (754) 238-2201 to schedule a measurement.

FAQs - Custom Windows & Doors in Key Biscayne
On Key Biscayne, every property is effectively waterfront. The island is surrounded by Biscayne Bay on one side and the Atlantic on the other, so salt-laden air reaches interior lots from both directions year-round. Standard zinc-plated or plain steel hardware corrodes, seizes, and fails on this island at a rate that would take decades on the mainland. Marine-grade stainless steel and sealed hardware are not an upgrade here. They are the minimum spec for a window or door that will still open and lock in year six. Call (754) 238-2201 for a quote on a marine-spec replacement.
A Miami-Dade Notice of Acceptance is a product approval proving that a specific window or door model passed impact and pressure tests under Florida’s strictest building code. Every replacement window or door in Key Biscayne must carry an NOA rating because the village sits entirely within the High Velocity Hurricane Zone. Without one, the permit will not pass and the condo association will not approve the work. TruePane only installs NOA-rated products for impact openings here, and we register the documentation with the manufacturer before the truck leaves the driveway.
No. Jalousie windows, the glass louvers common in mid-century Key Biscayne homes, cannot meet Miami-Dade impact standards with film applied. The frames are usually aluminum with worn pivot hardware, and the louver geometry will not pass HVHZ pressure testing regardless of the glass treatment. A building inspector will not sign off on film as an impact product. The correct fix is full window replacement with NOA-rated impact or insulated laminated units sized to the original opening. We can replicate the original look with custom exterior styling, but the glass must be code.
We coordinate with the condo board, the village, and a licensed crane operator to schedule a lift window, usually on a Saturday or Sunday morning when Crandon Boulevard traffic is lighter. The old units come out, the new NOA-rated custom-sized units go in, and the crane clears the street by permit deadline. We recently replaced corroded original sliding glass doors in a 1970s condo tower along Crandon Boulevard this exact way. The original multi-point locking hardware had seized from salt air, and the single-pane glass failed the HVHZ impact test. We craned custom-sized NOA-rated insulated glass units with stainless steel hardware over the boulevard, swapped the old flashing tape for a marine-grade butyl system, and the owners now have argon-filled low-E glass with a U-factor below 0.30 and no more fog between panes.
The short answer is salt, code, and crane time. Key Biscayne requires NOA impact ratings and marine-grade hardware on every opening, while Coral Gables, several miles inland, can pass inspection with lighter hardware and lower wind-load ratings on many structures. On the island, upper-floor condo work often requires a crane lift and a street closure permit. Those costs are real and they are specific to the island. A Coral Gables installer who quotes Key Biscayne work without those line items is quoting the wrong job. We put every line item on paper before we start, so the price we quote is the price you pay.
