Door Installation in Key Biscayne - Free In-Home Measure, Written Price

Fast, Reliable Door Installation Across Key Biscayne

Replacing a door on Key Biscayne isn’t like replacing one in Kendall or Coral Gables. You’re on a barrier island surrounded by saltwater, inside Miami-Dade’s High Velocity Hurricane Zone, which means every single opening in your home, even a back door to a laundry room, has to meet the strictest impact standards in the country. A typical entry door replacement in Key Biscayne runs $2,800 to $6,500 installed, depending on the door, the frame condition, and what we find when we open the wall. Our crews work on Key Biscayne weekly, we know exactly what Crandon Boulevard condos and interior island homes throw at us, and we answer the phone when you call (904) 478-8983.

Ed Winslow’s name is on the door, and on every job we do. We’ve been installing impact-rated entry doors, French doors, and replacement doors on Key Biscayne long enough to know that the island’s salt air and wind loads punish anything installed half-correctly. If you’re thinking through a door project, this page explains what it actually costs here, what the code requires, and what we see behind the walls of 1960s and 1970s island buildings.

Why Winslow Windows & Doors Is Key Biscayne’s Preferred Door Installation Company

We’re owner-operated, founded in 2011, and locally owned by Ed Winslow, with a published address and license number. Not a franchise. Not a call center that dispatches whoever’s free. When you call, a live person answers, 24 hours a day, seven days a week. That matters on Key Biscayne, where a failed door seal during a storm or a corroded lock on a condo entry isn’t a next-business-day problem.

Our technicians are background-checked and arrive in uniform, so you know exactly who’s walking up to your door before they knock. We install eight authorized brands, including PGT, CGI, and Therma-Tru, which gives us real flexibility matching a door to your building’s wind zone and your HOA’s design requirements. And every job carries the Done Right Promise: if it’s not done right, we make it right. No fine print, no expiration.

For Key Biscayne specifically, we stock marine-grade stainless hinges, locksets, and thresholds because we know what the island’s salt spray does to standard hardware. Our crews understand the Rickenbacker Causeway commute and schedule accordingly. We’re not learning your island when we show up; we already know it.

Our Door Installation Services in Key Biscayne

Entry Doors

An entry door on Key Biscayne does more than welcome guests. It’s your first line of defense against wind, water, and whoever shouldn’t be getting in. We install fiberglass and steel entry doors from Therma-Tru and PGT, each carrying a Miami-Dade NOA matched to the exact door, frame, and glass package. On a 1970s condo along Crandon Boulevard, our crew pulled a corroded aluminum entry door to find the jamb packed with rusted steel shims and the original opening out of square by nearly an inch. We replaced it with a PGT Therma-Tru fiberglass entry door carrying a Miami-Dade NOA, built a new treated jamb with stainless fasteners, and wrote the added framing labor into the change order before any new material went in. That’s how we handle surprise conditions on this island.

Hurricane-Proof Front & Entry Doors

Key Biscayne sits fully inside the HVHZ. There’s no opting out. A hurricane-proof front door here must carry a Product Control Notice of Acceptance from Miami-Dade County, specific to that exact configuration, and it must be installed to hold under the design pressures your specific opening demands. We install PGT and CGI impact doors tested for large-missile impact, and we pull the permit, pass the inspection, and hand you the paperwork your insurer wants to see. Homes in the interior of the island, especially single-family properties from the 1960s and 1970s, often have front doors that are structurally fine but code-obsolete. Your insurer already knows this. We fix it.

French & Double Doors

French doors facing Biscayne Bay or the Atlantic take a beating. Salt spray, wind-driven rain, and the constant humidity of a barrier island attack the seals, the hinges, and the thresholds. We install impact-rated French and double door systems from ES Windows and ECO Window Systems, engineered for coastal exposure and matched to Miami-Dade NOA requirements. For waterfront condos and homes on the east and west sides of the island, we upgrade to marine-grade stainless hardware as standard. If your double doors now are original to a 1980s build, there’s a strong chance the framing behind them has rot you can’t see from the outside.

Replacement Doors

Most replacement door work on Key Biscayne starts with a door that looks fine but isn’t. Locks corroded. Hinges sagging. The door sticks in summer and leaks in a storm. We remove it, inspect the rough opening, and rebuild what’s needed before the new door goes in. On older island condos, that often means new treated jambs, stainless fasteners, and re-shimming an opening that hasn’t been square since the original build. We write any framing correction into a change order and get your written approval before we touch it. No surprises on the invoice. That’s the Winslow way, and the Door Installation team handles it that way on every single job.

Trusted Brands We Service in Key Biscayne

We’re an authorized installer for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru. For Key Biscayne specifically, that matters in a way it doesn’t on the mainland. Mr-Glass and Therma-Tru units we specify for island jobs carry marine-grade hardware packages that hold up to daily salt exposure. We keep commonly needed parts and hardware accessible for Key Biscayne customers, so a corroded hinge or failed threshold doesn’t mean waiting weeks for a shipment. Call us at (904) 478-8983 and we’ll match your building’s requirements to the right brand, the right NOA, and the right installation protocol.

Common Door Installation Problems We See in Key Biscayne Homes

• Corroded hinges and locks from salt spray. Being encircled by open saltwater on all sides means the hardware on your doors ages years ahead of mainland Miami. We replace standard hardware with marine-grade stainless on every island install, because standard finishes fail in months, not decades.
• Undersized or rusted door jambs in older condos. 1960s and 1970s buildings along Crandon Boulevard and the waterfront often have jambs that can’t hold an impact-rated door under HVHZ design pressure. Contractors miss this, the door fails inspection, and the homeowner pays twice. We inspect first, then quote.
• Non-compliant wiring and rotted sheathing behind old door openings. Opening up a Key Biscayne wall from that era frequently reveals wiring that doesn’t meet current code and sheathing that’s been quietly rotting from decades of humidity. The permit process triggers code upgrades, and we write allowances into the contract so you’re not ambushed mid-job.
• Jalousie doors on older guest cottages. Jalousie doors are not just old. They’re uninsurable and out of compliance with Miami-Dade HVHZ code. Insurers ramped up non-renewal notices after Hurricane Irma’s 2017 direct hit, and a jalousie door today is a liability your policy likely won’t cover.

Pricing for Door Installation in Key Biscayne, FL

What Door Installation Costs in Key Biscayne

For impact-rated windows and doors as a broader reference: impact windows in this market generally run $800 to $1,500 per window installed; impact single-hung units land between $900 and $1,800; large or custom openings run $2,500 to $5,000; and whole-home packages range from $8,000 to $25,000 or more. For a single replacement door on Key Biscayne, the range stays tighter, usually $1,900 to $6,800 depending on the door type and what we find once the old door comes out. Floor height matters on the island: a door on the top floor of a mid-rise on the bay side has higher design pressure requirements than a ground-floor entry, and that gets reflected in the unit we specify. The frame material matters too: aluminum is cheaper but requires marine-grade finishes on the island, while fiberglass from Therma-Tru or PGT often makes more sense for saltwater exposure. We provide a free in-home measure and a written quote before any deposit is due.

Florida Pays You Back

Key Biscayne homeowners can stack several incentives on door and window replacement. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact-rated doors and windows are exactly what that program was built for. Florida also exempts impact-resistant windows and doors from sales tax, which takes 6% to 7% off your project right away. On the federal side, the 25C energy credit returns 30% of the product cost, up to $600 per year, on qualifying energy-efficient units. And after a wind-mitigation inspection (typically $75 to $150), most Key Biscayne carriers apply a windstorm-premium credit averaging around 25% on the windstorm portion of your policy. We don’t guarantee any specific rebate or credit amount, because the programs and the carriers set those numbers, but we’ll walk you through which of our doors qualify and what paperwork you’ll need.
