Windows & Doors Services in Key Biscayne, FL
If your windows are fogged, your sliding door fights you every afternoon, or you’re looking at a 1970s condominium unit with original aluminum frames, you already know the problem. Key Biscayne is not a typical market. Sand-laden, salt-heavy wind works both sides of this barrier island, and glass that was installed before Hurricane Andrew simply will not hold up the way it should. TruePane Windows & Doors has answered calls on Key Biscayne for years, and a live person still picks up the phone at (954) 507-3613 when you call to ask about a free estimate.

Why Key Biscayne Homeowners Choose TruePane Windows & Doors
Key Biscayne homeowners are not looking for the cheapest bid. They are looking for someone who will still answer the phone in ten years if a seal fails or a door binds. That is the reason we keep our shop standards in writing, and why the Key Biscayne communities of Ocean Club and Commodore Club call us back year after year. Every job carries the Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves the driveway, and everything backed by the Done Right Promise. If the pane is not true, the job is not done.
We’re second-generation glaziers, not a franchise playbook. Dale Kessler founded TruePane in 2008 on a principle he had been living for decades: out-of-true installs and voided warranties are problems that can be fixed permanently. Our background-checked, uniformed technicians measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck pulls away. No paperwork fights, no fine print that covers neither warranty.
Windows & Doors Services We Offer in Key Biscayne
Window Installation
We set new windows square and level in Key Biscayne homes, from condo replacements to full single-family builds. Every install goes in with a Miami-Dade County NOA-compliant product and gets both warranty layers registered in writing. Learn more about our Window Installation in Key Biscayne.

Door Installation
Front entry doors, terrace doors, and code-compliant impact doors, installed to close clean and seal tight against salt air and storm pressure. We align jambs and thresholds the first time, so the door doesn’t bind when the humidity climbs in August. Learn more about our Door Installation in Key Biscayne.

Window Replacement
Fogged seals, corroded tracks, and single-pane aluminum frames that rattle in a gust: those are the reasons replacement calls come from Key Biscayne’s older condo towers and pre-1992 homes. We pull the old unit, correct the opening, and set an impact-rated replacement that carries its full warranty. Learn more about our Window Replacement in Key Biscayne.

Impact Windows & Doors
In Evacuation Zone A, impact glazing is not an upgrade; it is the only responsible spec for a barrier island. We work with CGI, CWS, ES Windows, and ECO Window Systems to get Key Biscayne homes the right NOA’d impact package, not just a shutter note from a salesman. Every unit is staged on-island before we break a single existing frame.

Energy-Efficient Windows
Salt fog and afternoon heat load are a two-front war on barrier island glass. We size energy-efficient window systems that reduce solar gain, hold cool air, and resist the corrosion that eats standard frames five years earlier than mainland installs.

Sliding & Patio Doors
Aluminum sliding doors from the 60s and 70s are the most common call we get from Key Biscayne condos. We replace them with properly bedded, NOA’d sliders that move easily and seal tight, or service the original track and rollers if the door itself is still sound. The job gets a square deal, either way.

Glass Railing Systems
Bayfront condos and single-family terraces on Key Biscayne often call for frameless glass railing that holds up against wind, salt, and sun. We measure, cut, and set railings to spec, and we register every manufacturer warranty before the cleanup starts.

Custom Windows & Doors
Some Key Biscayne homes have openings that no off-the-shelf unit will fit. We order custom-sized windows and doors through authorized lines, matched to the existing architecture, and install them with the same Keystone Standard as our stock work.

Why Key Biscayne’s Climate & Housing Affect Windows & Doors
Key Biscayne is a barrier island flanked by Biscayne Bay to the west and the open Atlantic to the east, which means every structure sits in a dual-exposure marine salt-air environment. It is one of the most corrosive in the continental U.S., and it shows. In buildings like Commodore Club and Ocean Club, we regularly see original aluminum sliding doors with pitted frames, corroded rollers, and seals that started failing years ago. The salt spray off the bay and the Atlantic simultaneously means frames, hardware, and seals corrode measurably faster than equivalent installations five miles inland on the Miami mainland. Homes built before Hurricane Andrew’s 1992 code overhaul often still carry jalousie windows and single-pane aluminum frames that predate Miami-Dade’s impact-glazing requirements. Those units can’t be repaired into compliance. They need replacement.
Every window and door replacement on Key Biscayne must carry a Miami-Dade County Notice of Acceptance, the strictest product-approval standard in the nation. That fact alone makes this market categorically different from any mainland Miami neighborhood just across the Rickenbacker Causeway. A contractor who does not understand the NOA requirement, or who thinks a glass catalog number is enough, will cost you time and money.
Pricing for Windows & Doors in Key Biscayne
Pricing on Key Biscayne reflects the product and the paperwork, not a markup. You should expect these working ranges:
- Window replacement (standard NOA’d impact unit): $900-$2,400 per opening, depending on size and line
- Sliding glass door replacement (impact rated): $3,200-$8,500
- Entry door replacement (impact rated): $2,800-$6,400
- Glass railing systems: $220-$380 per linear foot
- Custom window or door: quoted per opening, never per guess
These are honest ranges for Key Biscayne’s NOA and salt-spec market. The exact number comes down to what is behind the old frame and what manufacturer line you choose. Call (954) 507-3613 for a free estimate with a written line-item quote.

FAQs About Windows & Doors in Key Biscayne
Most Key Biscayne impact window replacements run between $900 and $2,400 per opening, depending on size, manufacturer line, and what we find when the old frame comes out. Condo buildings with strict association specs usually land at the higher end. Call (954) 507-3613 for an exact quote. Estimates are free.
No. We quote in writing before we start, and the price does not change unless we uncover hidden structural damage that requires an additional scope. In that case, we stop and get your approval in writing before any extra work. No surprises on the bill.
Yes. We handle the Miami-Dade County permit process on every Key Biscayne job. When an association requires NOA documentation or board approval, we prepare and submit that paperwork as part of the job, and we register both warranty layers before the truck leaves the driveway.
Most single-unit replacements are completed in a single visit. Larger jobs, such as full condo unit impact packages or multi-door replacements, typically run two to five working days depending on the scope and building access. We stage all windows and doors on-island before breaking a single existing frame, so the Rickenbacker Causeway is never the reason your job stalls.
Yes. We see the 1960s through 1980s aluminum sliders in buildings like Ocean Club and Commodore Club constantly. In many cases we can service the original track and replace rollers. When the frame is pitted and the seals are gone, we replace the door with a properly bedded, impact-rated unit that meets Miami-Dade NOA requirements. Either way, the job gets a square deal. Call (954) 507-3613 and we’ll tell you which side of the line your door is on.

What Key Biscayne Customers Say
"Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
