Window Company in Key Biscayne, FL
Westlight Windows & Doors handles window and door work across Key Biscayne, from 1970s condominium buildings on Crandon Boulevard to newer waterfront homes near the Cape Florida light. The island’s salt air and direct Atlantic exposure mean most jobs here involve corrosion-damaged aluminum frames, failed seals, or impact ratings that no longer satisfy Miami-Dade County code. We carry eight manufacturer lines so the right glass, frame material, and hardware get matched to the job instead of forcing the job onto whatever happens to be on a truck. Call (850) 753-2730 and you’ll reach a real person, not a voicemail box.
Why Key Biscayne Homes Are Different
Key Biscayne is a barrier island, and nothing about that is abstract when you’re standing in front of a 17th-floor condo window with salt crust on the track. The air here carries Atlantic moisture year-round, so untreated aluminum frames pit and corrode within a few seasons. Glass seals give out faster than they do a few miles inland. Sliding glass doors that face the ocean take wind-driven rain and sand directly, and once the weatherstripping degrades, water finds its way in.
The housing stock compounds the issue. Many Key Biscayne buildings went up between the 1970s and early 2000s, a period when impact-rated glazing was not yet standard. Those original windows and sliders often carry outdated product approvals or none at all. Miami-Dade County enforces one of the strongest wind-borne debris codes in the country, and Key Biscayne applies it aggressively. We regularly see interior condo unit doors that require Miami-Dade product approval labels, not just exterior openings. If your building was built before the modern code chapters took effect, there’s a good chance the work you’re planning will involve bringing openings up to current standards, which means permits, inspections, and products with the right paperwork.
The terrain matters too. Access on the island is straightforward compared to mainland Miami, but high-rise work means freight elevators, condo association scheduling rules, and material staging that has to respect building staff and neighbors. We plan for that before the first crew member drives over the Rickenbacker Causeway.
Our Main Key Biscayne Services
Most calls we get from Key Biscayne homeowners fall into two buckets: replacing windows that have failed or no longer meet code, and installing new doors that can stand up to coastal conditions. Here’s what each involves on the island.
Window Replacement in Key Biscayne
Most window replacement work in Key Biscayne is driven by salt corrosion on aluminum frames, failed insulating glass seals, or impact ratings that predate current Miami-Dade wind-borne debris rules. Replacing an old aluminum window in a condo or single-family home usually means specifying a new impact-rated unit, often with low-e glass (a thin coating that reflects heat back into the room in winter and out in summer) and stainless steel hardware. Some buildings have specific aesthetic standards, and we work with association requirements on frame color and sightlines. Window Replacement in Key Biscayne is covered in detail on its own page, including what a typical replacement costs and how long high-rise jobs take.
Window Installation in Key Biscayne
New-construction and addition window installation in Key Biscayne has to pass inspection the first time, because re-scheduling an inspector on the island wastes a week. Buildings here are held to wind-load and water-penetration standards that many mainland installs never face. We install new windows into fresh openings or remodeled walls, flash them correctly for hurricane-driven rain, and make sure every unit’s product approval label is documented before the inspector walks in. Window Installation in Key Biscayne explains the full scope, including what distinguishes installation from replacement when it comes to framing and waterproofing.
Door Installation in Key Biscayne
Door installation on Key Biscayne often starts with the same issue as windows: salt air has eaten the hardware, the hinges, or the bottom rail of the frame. Exterior doors facing the ocean need marine-grade stainless hardware, and in condo buildings, even the front entry door to an interior hallway unit may need a Miami-Dade product approval label. We install entry doors, sliders, and French doors with proper sill pan flashing so wind-driven rain doesn’t find its way under the threshold. Door Installation in Key Biscayne covers products, lead times, and what door work costs on the island.

What Key Biscayne Customers Say
"Nice windows and a clean install. There was a small delay getting one of the windows from the manufacturer, so one opening was done a couple weeks after the rest. They communicated it though."
- Walt Prentiss"Our energy bill in summer was brutal. New windows made a real dent in it. Salesman wasn't pushy and didn't do the fake "today only" discount thing the others tried."
- Bethany Oh"Replaced eight drafty old windows that were basically single pane. The house is warmer already and the street noise is way down. Crew was on time both days and the price was exactly the quote."
- Harold Bemis
