AfterFast, Reliable Door Installation Across Key Biscayne
Door installation in Key Biscayne runs between $1,800 and $6,500 for a typical entry door, with hurricane-rated front doors falling between $3,200 and $8,000 depending on size, glass package, and finish. Most installations take one day once your unit arrives, though custom fabrication adds 4 to 6 weeks. If you live on this island, you already know the problem: salt air eats steel, and Miami-Dade code demands impact ratings most installers on the mainland barely understand.
We’re Winslow Windows & Doors, and we’ve been helping Key Biscayne homeowners replace corroded, outdated, or storm-vulnerable doors since Ed Winslow founded this company in 2011. Our Door Installation team knows the island’s condo boards, its wind zone, and its salt spray. Call (863) 656-0462 and a live person answers. Always.
Why Winslow Windows & Doors Is Key Biscayne’s Preferred Door Installation Company
Key Biscayne is a small island with a short list of contractors who actually understand what it takes to install a door here. We’re one of them. The salt air that rolls off Biscayne Bay and the Atlantic doesn’t just rust hardware, it corrodes door jambs, seizes hinges, and crumbles weatherstripping years before the same materials would fail in Coral Gables or Kendall. A mainland installer might never see that. We see it every week along Crandon Boulevard, over by the Village Green, and up in the towers near Cape Florida.
Ed Winslow’s name is on the business. That’s not a tagline. It means when a Key Biscayne customer calls about a door that’s binding or a threshold that’s pulling away, Ed hears about it. Our technicians arrive in uniform, background-checked, and they know the difference between a 316 marine-grade stainless hinge and the cheaper 300-series that pits within two years on this island. We publish our address and license number. We answer the phone at 2 a.m. And we stand behind every door with the 36500-Day Done Right Promise: if it’s not done right, we make it right. Period.
Our Door Installation Services in Key Biscayne
Entry Doors
A front door on Key Biscayne does more than welcome guests. It’s the first line of defense against wind-driven salt spray and hurricane-force gusts. We install Therma-Tru and PGT entry doors sized and rated for your specific opening, with design pressures matched to Miami-Dade’s High-Velocity Hurricane Zone (HVHZ). Whether you’re in a 1970s condo off Crandon Boulevard or a single-family home near the golf course, we measure, order, and install with the same care we’d give our own front door.
Hurricane-Proof Front & Entry Doors
This is the product category that matters most on a barrier island. A hurricane-proof door in Key Biscayne must carry a Miami-Dade Notice of Acceptance (NOA) and withstand both positive and negative wind pressures, plus missile impact. PGT impact-rated doors with laminated glass interlayers are our most-specified unit here. The interlayer holds the glass together if a 2×4 or roof tile hits it at 140 mph. You don’t hang shutters over that. You lock it and leave.
French & Double Doors
French doors facing the bay or Atlantic are beautiful until the salt air finds the seam between panels. We install French and double doors with marine-grade hardware, reinforced corners, and upgraded compression seals that survive coastal exposure. On Key Biscayne, we recommend active double doors with impact-rated glass and stainless fasteners at every point of contact. The view stays. The corrosion doesn’t.
Replacement Doors
If your existing door sags, binds at the threshold, or lets daylight through the weatherstripping, replacement is cheaper than chasing salt damage piece by piece. We pull the old unit, inspect the rough opening for rusted fasteners or spalled concrete, and set the new door plumb and square. Most replacements in Key Biscayne condos also require association approval, which we help you document and submit.
Storm & Exterior Doors
Storm doors on the mainland are nice. On Key Biscayne, they’re protective armor for your primary entry door. We install storm and exterior doors with corrosion-resistant frames and impact-rated glass where code requires it. The right storm door shields your main door from direct salt spray, extends its life by years, and gives you ventilation when the sea breeze is right.

Trusted Brands We Service in Key Biscayne
We’re an authorized installer for eight premium brands, and we stock service parts for the ones Key Biscayne homeowners rely on most. Therma-Tru for entry doors that hold their finish in coastal air. PGT for impact ratings that meet HVHZ. ECO Window Systems and ViewLux for configurations other installers can’t get. If you have an existing door from any of these brands and it’s failing early, bring us the paperwork. We’ll tell you honestly whether it’s a spec problem or a salt problem, and what to do next.
Common Door Installation Problems We See in Key Biscayne Homes
- Corroded steel jambs and hinges. Constant salt spray attacks steel at the threshold first, then the hinge plates. We’ve pulled doors where the bottom hinge crumbled in our hands. The fix is 316 marine-grade stainless hardware and a properly sealed opening.
- Hardened, cracked rubber gaskets. On Key Biscayne, rubber weatherstripping loses its compression set in 5 to 8 years, not 15. When gaskets crack, salt air infiltrates the door frame and corrodes internal hardware you can’t see until it fails.
- Pitted stainless fasteners. Not all stainless is equal. 300-series fasteners pit and rust in coastal environments. We spec 316 marine-grade at every attachment point, because a door is only as strong as what holds it to the concrete.
- Condo board rejection after code approval. You can pass Miami-Dade code and still get denied by your association because the frame color is one shade off. We’ve seen it. We document the board’s required finish and glass tint up front, so you don’t burn weeks waiting for a redo.
Key Takeaways
- Key Biscayne sits entirely inside Miami-Dade’s HVHZ, so every replacement door must carry a NOA.
- Salt air corrodes steel jambs, hinges, and fasteners years faster here than on the mainland.
- Most condo associations on the island require written approval before an exterior door can be replaced.
- We install PGT, Therma-Tru, ECO Window Systems, and ViewLux, all with marine-grade hardware and stainless fasteners.

Pricing for Door Installation in Key Biscayne, FL
A standard entry door replacement in Key Biscayne typically runs $1,800 to $4,200. Hurricane impact-rated front doors range from $3,200 to $8,000 depending on glass package, size, and finish. French or double door installations fall between $4,500 and $9,500 when both panels are impact-rated and fitted with marine-grade hardware. Storm doors and exterior doors add $700 to $2,500 on top of the main entry unit.
What moves the price here more than anything is the dual approval chain: the product must pass Miami-Dade code AND your condo board’s aesthetic requirements. A door that passes code but gets rejected by the board costs you weeks and a resubmission. We capture board specifics before we order, so you pay for one door, not two attempts. Estimates are free. Call (863) 656-0462.
What Door Installation Costs in Key Biscayne
Here’s how the numbers break down on a barrier island with HVHZ requirements:
- Entry door replacement: $1,800 to $4,200
- Hurricane impact-rated front door: $3,200 to $8,000
- French or double door, impact-rated: $4,500 to $9,500
- Storm or exterior door: $700 to $2,500
- Whole-home door package (3+ doors): $9,000 to $24,000
Floor height matters in Key Biscayne. An impact door on the 12th floor of a condo tower faces higher wind pressures than one on a ground-level home near the Village Green, and the design pressure rating has to match the opening. Frame material matters too. Aluminum frames resist corrosion better than steel but cost more. We’ll walk you through every line item during the free measure. No vague “it depends” answers. You’ll see the real numbers before you sign anything.
Florida Pays You Back
Key Biscayne homeowners don’t get a price break at the permit counter, but the state and federal incentives soften the cost of impact-rated doors significantly. You can stack these:
- My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact doors.
- Florida sales-tax exemption applies to impact-resistant windows and doors. You don’t pay sales tax on qualifying units.
- Federal 25C energy credit gives you 30% of product cost back, up to $600 per year, on qualifying energy-efficient doors.
- Windstorm-premium credits average around 25% off the windstorm portion of your insurance after a wind-mitigation inspection runs $75 to $150.
We don’t guarantee what insurers or state programs will pay. Those numbers change. But we’ll help you document the installation so you can claim every credit you’re owed.

FAQs - Door Installation in Key Biscayne
Because your association owns the building’s exterior appearance, and most Key Biscayne boards write specific aesthetic requirements into their governing documents: frame color, glass tint, even hardware finish. A door that passes Miami-Dade’s HVHZ code can still be rejected by the board if it doesn’t match the building’s uniform street-facing look. We collect those board requirements before we order, and we prepare the documentation your association needs. Call (863) 656-0462 and we’ll help you avoid the rejection loop.
Plan for 5 to 8 years on gaskets and weatherstripping, and 8 to 12 years on hinges and hardware, versus 15 to 20 years on the mainland. The salt spray and humidity on Key Biscayne compress that timeline hard. If you’re seeing white oxidation on hinges or daylight through the weatherstripping, it’s time. We spec marine-grade replacements that buy you more time.
Sometimes yes, but often no in practice. Florida Product Approval is a statewide standard, but Key Biscayne sits inside Miami-Dade’s HVHZ, which requires a Miami-Dade Notice of Acceptance (NOA) with specific design pressure ratings for your exact opening. A door with only a Florida Product Approval may not carry an NOA for your wind zone. We verify the NOA before we recommend any unit. Call (863) 656-0462 and we’ll pull the approvals on the door you’re considering.
Corroded steel jambs at the threshold. We recently replaced an oceanfront entry door in the emerald-green condos on Crandon Boulevard where the original steel jamb had rusted through completely at the bottom, and the rubber gaskets had hardened to brittle flakes. We installed a PGT impact-rated door with a laminated glass interlayer and stainless-steel hinges, then waited three extra weeks for the association’s board meeting to approve the exact frame color match to the building’s original 1970s palette. That’s the job on Key Biscayne: engineering plus board diplomacy.
Because the door that looks the same may not be the same under the skin. The price gap usually comes down to three things: the design pressure rating on the NOA, the grade of hardware, and the type of glass interlayering. A door rated for a ground-level opening costs less than one rated for a 10th-floor exposure. Marine-grade hinges and fasteners cost more than standard stainless. And laminated impact glass with a thicker interlayer costs more than a thinner one. We show you the line items so you know exactly what you’re paying for. Estimates are free at (863) 656-0462.
