AfterFast, Reliable Custom Windows & Doors Across Key Biscayne
Custom window and door work in Key Biscayne is not a mainland job. Every structure on this barrier island sits in the Miami-Dade High Velocity Hurricane Zone, and the salt air here corrodes standard frames and hardware within a few years. We plan for that before we open the first wall. If you live in Key Biscayne and you’re pricing out custom windows or doors, call (888) 635-0804 for a free in-home measure and a written quote that covers the whole job, including what we find once the old units come out.
Our crews work across Key Biscayne regularly, from the condo lines along Crandon Boulevard to the single-family homes off Harbor Drive and Mashta Drive. We know the 33149 building stock, we know what the associations require, and we know that a window replacement here is rarely as simple as pulling one frame and setting another. The quote you get from us reflects that reality on paper, not as a surprise later.
Why TruePane Windows & Doors Is Key Biscayne’s Preferred Custom Windows & Doors Company
TruePane Windows & Doors has been doing this work under Dale Kessler’s name since 2008, built on a second-generation glazier’s craft tradition that goes back many years. That matters in Key Biscayne because this is not a market where a franchise playbook works. You need a crew that has opened walls in 1970s-era condos and found what hides behind them. We have.
Our Custom Windows & Doors team works the way this island requires: every opening measured twice, every product line quoted side by side on paper, and both manufacturer warranty layers registered in writing before the truck leaves the driveway. That is the Keystone Standard, and it applies to every job in Key Biscayne, from a single impact casement on a third-floor condo to a full-home replacement on West Mashta Drive.
When homeowners in Key Biscayne call us, a live person answers. Not a voicemail tree, not a callback form. You tell us what you’re seeing, and we schedule a uniformed, background-checked technician to come measure and inspect. If the pane is not true, the job is not done. That rule governs everything we install.
Our Custom Windows & Doors Services in Key Biscayne
Custom Impact-Rated Window Fabrication
Key Biscayne requires Miami-Dade Notice of Acceptance numbers on every impact-rated window we install, without exception. We fabricate custom units to the exact rough opening, with design pressures matched to the opening and the floor height. No generic stock sizes forced into an opening that was never square to begin with.
Window and Door Retrofitting with Marine-Grade Hardware
Salt spray here comes from both the bay and the ocean at once during storms. Standard aluminum hardware fails within two or three years on Key Biscayne. We retrofit windows and doors with marine-grade hardware and reinforced sill drainage that stands up to the island’s 360-degree salt exposure. The same unit that would be over-specified in Kendall is baseline here.
In-Wall Discovery and Structural Framing Repairs
When we open a wall on a 1970s Key Biscayne condo, we expect to find something. Rotted subsills, corroded original jambs, failed waterproofing behind stucco. We inspect first, write the framing upgrade into a change order before we touch another inch, and sister in pressure-treated lumber where the original material lost structural integrity. The price is approved in writing before the work happens.
Custom Door Replacement
Entry doors, terrace doors, and sliding patio doors on Key Biscayne take a beating from wind-driven rain and salt. We build and install custom doors with marine-grade frames, reinforced thresholds, and proper sill drainage to HVHZ standards. A door that binds in July is usually a door that was never set true in the first place. We set it true the first time.

Trusted Brands We Service in Key Biscayne
We are an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. We also work with ECO Window Systems, Therma-Tru, and ViewLux for specific configurations and hardware needs. For Key Biscayne customers, we keep common marine-grade hardware and replacement parts in local inventory so turnaround stays short. If your existing window brand is one we service, we can usually handle the repair or replacement without waiting on a distant distributor. If it is not, we will tell you that on the first call.
Common Custom Windows & Doors Problems We See in Key Biscayne Homes
- Corroded original aluminum frames. The 1960s through 1980s condos along Crandon Boulevard and Harbor Drive were built with single-pane aluminum that was never designed for HVHZ standards. When we open those walls, the jambs often crumble in our hands.
- Failed sill pans and waterproofing. Many Key Biscayne buildings predate current HVHZ drainage standards. We regularly uncover rotted subsills that must be rebuilt before a new window can be set and pass inspection.
- Hardware seized by salt within two to three years. Even newer windows fail fast here if they were not specified with marine-grade hardware. The 360-degree salt-air exposure is relentless, worse than anything mainland Miami sees.
- Condo association approval delays. A window swap that takes weeks in Miami can take months on Key Biscayne because board votes, architectural review, and county permitting all stack up. We plan the schedule around that reality and keep you informed at each step.
Pricing for Custom Windows & Doors in Key Biscayne, FL
Impact windows in Key Biscayne generally run $800 to $1,500 per window installed. A custom impact single-hung runs $900 to $1,800. Large or fully custom openings, including corner windows and oversized sliders, run $2,500 to $5,000. Whole-home packages typically land between $8,000 and $25,000 or more depending on opening count, floor height, and frame material. Key Biscayne adds a layer the mainland does not: condo association review timelines, HVHZ documentation, and structural discoveries once walls are open. We write allowances into the contract for exactly that reason. Call (888) 635-0804 to schedule a free in-home measure and get a written quote that covers the job, not a teaser number that moves later.
What Custom Windows & Doors Costs in Key Biscayne
The numbers above are real anchors for this market. What moves your price in Key Biscayne specifically: the number of openings, the wind zone requirements for your floor height, whether the building requires architectural review, and what we find behind the old frames. A standard impact window on a first-floor condo costs less than a large-missile-rated unit on the eighth floor with a custom finish. Frame material matters too: marine-grade aluminum and impact-rated vinyl carry different numbers. The honest way to price your job is to have us measure and inspect each opening. The quote is free, it is in writing, and it includes the allowance language that protects you if the wall hides something. Call (888) 635-0804 to schedule it.
Florida Pays You Back
Key Biscayne homeowners have more than one way to offset the cost of impact windows and doors. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida also provides a sales-tax exemption on impact-resistant windows and doors, which keeps real money in your pocket at purchase. The federal 25C energy credit returns 30% of the product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection, which typically runs $75 to $150, many Key Biscayne homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of their policy. Programs and carriers set the final numbers, not us. We will quote your project honestly and point you to the right documentation so you can pursue every incentive that applies.
One thing worth weighing before you commit: impact windows versus hurricane shutters. Shutters protect during a storm, but you hang them, store them, and they do nothing for your daily energy bill or your property value. Impact windows are permanent protection. No panels to haul out before a storm, no brackets to maintain, and they work every hour of every day, not just when a named storm is bearing down on Key Biscayne. For most homeowners on this island, the permanent option wins.

FAQs - Custom Windows & Doors in Key Biscayne
We stop work on the window itself and bring you to the opening to show you what we found. Then we write a change order that covers the framing repair, the materials, and the labor, and we get your signature before we touch another inch. No work happens on a surprise basis, and the price is approved in writing first. Call (888) 635-0804 if you want to talk through how we handle these discoveries before you commit.
Yes, in nearly every case. The HVHZ applies to the entire island, and Miami-Dade requires a Notice of Acceptance for every impact-rated product installed, regardless of when the building went up. Older buildings are not grandfathered out of the current requirement for new installations. We handle all the NOA documentation as part of the job, so the paperwork is not something you chase on your own.
We build an allowance into your contract before we start, so you know the ceiling and the scope ahead of time. If we open the wall and the framing is sound, the allowance stays unused and you do not pay it. If we find rot or corrosion, we show you the condition, write the specific repair into a change order with a clear price, and proceed only after your approval. No arguments, no surprise line items. Call (888) 635-0804 for an exact quote on your project.
Because of the condominium approval process. Key Biscayne condo associations must satisfy Miami-Dade HVHZ requirements, Florida condominium statute approval processes, and often architectural review standards, all before the first window is ordered. A single-family home on the mainland can have windows fabricated and installed within weeks. A condo on Key Biscayne may wait months for board votes and county permitting. We build that timeline into the schedule and keep you informed at each stage.
You could, but it would fail faster. The same product that performs adequately across the Rickenbacker Causeway will see accelerated hardware corrosion and seal degradation here because Key Biscayne is a low-lying barrier island with salt spray from both the bay and the ocean. We specify marine-grade hardware and reinforced sill drainage as the baseline for every Key Biscayne installation. It is not an upsell; it is what this island requires. Call (888) 635-0804 and we will quote your project with the right materials the first time.
