Fast, Reliable Door Installation Across Key Biscayne
Door installation in Key Biscayne runs $900 – $6,800 depending on whether you’re replacing a standard interior door, a storm-rated exterior entry, or a full sliding glass assembly. Most single entry door replacements on the island fall between $1,400 and $3,200 installed, including tear-out and disposal. If you live in a condo on Crandon Boulevard or a waterfront home near Mashta Island, you already know the salt air doesn’t give doors a long retirement.
Our crews work Key Biscayne regularly, coordinating from our Miami office. We know the Rickenbacker Causeway traffic, the condo association rules, and the code requirements that mainland contractors sometimes miss. Call (850) 753-2730 for a free estimate, and you’ll get a written price before any work starts.
Why Westlight Windows Miami Is Key Biscayne’s Preferred Door Installation Company
We’re an independently owned and operated Kingswell location, founded in 2009, and led by Owen Satterfield. Owen started this company because he kept hearing the same story from homeowners: a contractor quoted one price, then “discovered” problems at the door. That doesn’t happen with us, because every job is governed by the Kingswell Guarantee: a written price before work starts, a committed arrival window, a clean job site, and a written guarantee on the completed work.
Key Biscayne customers call us back for a few reasons. Our technicians are background-checked and uniformed, so you know exactly who’s walking through your condo lobby or front gate. We carry eight manufacturer lines, including impact-rated PGT and CGI, which matters when your building requires Miami-Dade product approval on every opening. And our phone lines are staffed by a live person 24 hours a day, seven days a week. No voicemail box. No chatbot. When a sliding door won’t latch at 9 p.m. before a storm watch, a real human picks up.
We also understand the island’s rhythms. Parking constraints at condos on Ocean Drive mean we arrive with everything staged in the truck. Elevator time windows at buildings near Bill Baggs Cape Florida State Park mean we schedule carefully and show up in the window we gave. That’s the Kingswell Way: say the price before the work, show up when we said, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.
Every Door Installation job we complete in Key Biscayne gets the 365-Day Done Right Promise. If the work isn’t right within the guarantee period, we return and correct it at no charge. No negotiating. No fine print. It’s a written promise handed to you at job completion.
Storm Door Installation in Key Biscayne
What Storm Door Installation Involves on a Barrier Island
Storm Door Installation on Key Biscayne is not the same job as it is ten miles inland. Here, a storm door isn’t just a second layer; it’s often the first line of defense against wind-driven rain and flying debris during a hurricane watch. We install storm doors with impact-rated glass, heavy-gauge frames coated against salt corrosion, and stainless steel hardware that won’t seize after two seasons of ocean air. A quality storm door in Key Biscayne typically runs $1,800 – $3,600 installed, depending on size and whether we’re retrofitting an existing opening or doing a full tear-out.
When we install a storm door on a single-family home near the Village of Key Biscayne, we check the existing jamb for salt pitting first. If the frame is compromised, the storm door won’t seal, no matter how good the door is. We’d rather tell you that upfront than install a door that fails the next wind mitigation inspection.
Hardware That Survives the Salt
Entry doors facing the Atlantic catch more than wind. Airborne salt crystallizes inside standard hinges and handles within 12 – 18 months, leaving doors that won’t latch properly and fail wind mitigation requirements. For ocean-facing doors, we specify marine-grade stainless hinges, powder-coated handlesets, and corrosion-resistant threshold caps. It adds $180 – $400 to the project, and it’s the difference between a door that works for a decade and one that seizes in two years.
Sliding Glass Door Installation in Key Biscayne
Why Inland Sliders Fail Here
Sliding Glass Door Installation on Key Biscayne demands materials that most mainland sliding doors never need. The aluminum tracks and rollers on standard sliders corrode and bind within a few years of salt exposure. The sash gets stuck, gaps open up, and your air conditioning pours out through the seams. We regularly replace sliding glass doors at condos on Crandon Boulevard where the aluminum frame has pitted so badly the jamb no longer seals against wind-driven rain.
At one condo on Crandon Boulevard, our crew removed a corroded sliding glass door and installed a PGT impact-rated unit with a laminated glass interlayer and stainless steel rollers. We also replaced the adjacent Therma-Tru entry door hardware after finding the old hinges fused by salt. The homeowner had been fighting that slider for two years before calling us.
Expect to pay $2,800 – $6,800 for a sliding glass door replacement on Key Biscayne, depending on the opening size and whether the building requires Miami-Dade product approval labels. That’s a significant spread, and it reflects real differences in glass, frame coating, and hardware.
Impact-Rated vs. Standard Sliding Doors
A standard inland sliding glass door with tempered glass costs less upfront. It also fails the structural pressure test during a Category 1 storm, leaks conditioned air year-round, and won’t pass a building inspection on Key Biscayne. The island enforces wind-borne debris protection codes that make impact-rated laminated glass the default, not an upgrade. You’re not paying a premium so much as you’re avoiding a door that gets flagged the next time your association runs a compliance review.
Trusted Brands We Service in Key Biscayne
We install and service doors from PGT, CGI, Therma-Tru, and ECO Window Systems, among others. Because we stock parts for these lines locally, we don’t make Key Biscayne customers wait two weeks for a replacement roller or hinge. If your condo board requires a specific brand or a Miami-Dade NOA number, call us at (850) 753-2730 and we’ll match the spec. We don’t force a job to fit one brand; we fit the brand to the job and the building’s requirements.
Common Door Installation Problems We See in Key Biscayne Homes
- Pitted aluminum frames: Airborne salt eats aluminum door frames within 8 – 10 years. The jamb warps, the door loses its seal, and wind-driven rain finds its way inside. Replacement with a properly coated frame and marine-grade hardware solves it.
- Corroded sliding door tracks: Salt crystallizes in the track, the sash binds, and eventually the door won’t move at all. We replace the track, rollers, and often the entire sash with stainless components rated for coastal exposure.
- Seized hinges and handles: Standard hardware on ocean-facing doors can seize within two seasons. We’ve seen doors that couldn’t be opened from inside during an evacuation drill. Marine-grade stainless hardware prevents this.
- Failed seal between frame and wall: Salt degrades the caulk and flashing around door frames, opening gaps that let humid air and water into the wall cavity. That leads to mold, rotted framing, and higher cooling bills. We remove the old sealant, inspect the rough opening, and re-flash with materials rated for a marine environment.

FAQs About Door Installation in Key Biscayne
Yes, in many condo buildings on Key Biscayne, even interior unit doors separating two air-conditioned rooms must carry a Miami-Dade County product approval label. The island’s enforcement of wind-borne debris protection codes extends to openings that mainland Miami typically exempts. If your association requires the label, we install doors that carry it. Call (850) 753-2730 and we’ll verify your building’s specific requirement before ordering.
Use marine-grade stainless steel hinges and handles. Standard hardware seizes from salt crystallization within 12 – 18 months on ocean-facing doors. We specify 316 stainless, which resists the pitting that cheaper grades develop. The hardware upgrade adds $180 – $400 per door and it’s worth every dollar on a barrier island.
You can, but it will likely fail your building’s next compliance review and may not pass a wind mitigation inspection. Standard tempered-glass sliders don’t meet the design pressure requirements for wind-borne debris protection on Key Biscayne. You’d save $1,200 upfront and spend more correcting it within a few years. Impact-rated units are the standard here for a reason.
Salt degrades standard caulk and flashing within two to three years on Key Biscayne, opening gaps that let humid air and water into the wall cavity. That leads to mold, rotted framing, and higher cooling bills. We use marine-grade sealants and flashing rated for coastal exposure, and we inspect the rough opening before reinstalling the frame.
A Miami-Dade NOA (Notice of Acceptance) is the stricter standard, required by some Key Biscayne condo boards. A Florida Product Approval is accepted in most other parts of the state. If your building requires an NOA, we’ll match you with a door that carries it. Call (850) 753-2730 and we’ll walk you through your building’s specific requirement.
