Key Largo sits on a narrow strip of coral rock with the Atlantic on one side and Florida Bay on the other. Nearly every home here takes salt spray from two directions at once, all year long, and that changes what a window or door actually needs to survive. TruePane Windows & Doors installs and services windows and doors across Key Largo, from canal-front stilt homes to CBS construction along US-1, and we answer the phone live when you call (954) 280-4413. We know what Monroe County code requires, what the salt does to mill-finish aluminum, and what holds up when a storm gets named.

They call us because they want the job done right the first time, by a company that will still answer the phone if something goes wrong. We work regularly in the canal neighborhoods off Ocean Bay Drive and the stilt-home communities along Tarpon Basin, and our uniformed, background-checked technicians measure every opening twice before a quote is ever written. Dale Kessler founded this company on a simple rule: if the pane is not true, the job is not done. That standard follows every install in Key Largo, whether it is a single replacement sash or a full house of Impact Windows & Doors in Key Largo. We register both manufacturer warranty layers in writing before the truck leaves your driveway, and every job is covered by our Done Right Promise.

Why Key Largo’s Climate & Housing Affect Windows & Doors
Key Largo
Key Largo is not a single-exposure coastal town. It is a narrow island strip with the Atlantic to the east and Florida Bay to the west, and the tidal canals running through most residential neighborhoods mean salt-laden air reaches both sides of nearly every house. Standard mill-finish aluminum frames pit and oxidize visibly within five to seven years on canal-front lots, because the canals hold relative humidity near 100% and deposit salt directly on the structure every single day. That is why we spec marine-grade anodized aluminum or impact-rated fiberglass frames as the baseline on any Key Largo canal-side job, not as an upgrade. Monroe County mandates 150+ mph design wind-speed impact-rated products throughout the Keys, and there is no windbreak anywhere on this island. The trade winds come in year-round, carrying salt from both shorelines. A seven-year-old aluminum window in Key Largo often looks worse than a twenty-year-old window in a mainland community. The stilt elevation on many homes adds another layer: windows and doors often sit eight to fourteen feet above grade, which changes staging, ladder work, and how the crew handles a 180-pound impact slider. A company that only works on slab-built mainland homes gets surprised by this. We do not.
Pricing for Windows & Doors in Key Largo
Window and door pricing in Key Largo runs higher than mainland Florida averages because of the mandatory impact-rated products and the logistics of island work. Here is what we typically see in this market.
- Single impact window replacement: $900-$2,400 depending on size, frame material, and manufacturer line.
- Impact sliding glass door: $3,500-$8,500 installed.
- Entry door replacement (impact-rated): $2,200-$6,000.
- Full home window replacement (10-15 openings): $14,000-$38,000.
- Glass railing system: $180-$350 per linear foot depending on hardware and glass type.
Every quote is line-item, on paper, and fixed. No change orders, no surprise line items. Call (954) 280-4413 and we will measure, price, and walk you through the numbers before you commit to anything.

FAQs About Windows & Doors in Key Largo
Monroe County requires impact-resistant fenestration products with Florida Product Approval throughout the Keys. Shutters are not accepted as an alternative on new installs here the way they sometimes are on the mainland. If you are replacing windows or doors in Key Largo, impact-rated units are the code requirement, not an option. Call (954) 280-4413 for an exact quote on impact windows, and we will show you manufacturer lines side by side on paper.
The tidal canals keep humidity near 100% and deposit salt directly on window and door frames daily, so mill-finish aluminum corrodes within five to seven years. We spec marine-grade anodized aluminum or impact-rated fiberglass on every canal-side job in Key Largo. Call (954) 280-4413 to schedule a free estimate and we will tell you exactly what your openings need.
Most single-opening replacements on stilt homes take a few hours once the crew is on site, but the elevated access and staging requirements add setup time compared to slab homes. Full home replacements in Key Largo typically run one to three days depending on the number of openings and the condition of the existing frames. Call (954) 280-4413 and we will give you a written timeline with your quote.
Plan on $900-$2,400 per impact window and $3,500-$8,500 per impact slider in Key Largo, with full home replacement typically landing between $14,000 and $38,000 depending on the number of openings and manufacturer lines you choose. Call (954) 280-4413 for a free, line-item estimate and we will price your exact openings, not a ballpark.
No. We quote fixed line-item pricing on paper, and we do not change the number after the job begins.

What Key Largo Customers Say
"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."Two entry doors. Showed up when they said, second day was a half day like they said, and the painter they recommended confirmed the frames were dead plumb. The financing was explained in actual dollars, not a brochure."
- Janet R."Storm door and a new back entry door. Small job, but they treated it like one that mattered. Screws in the hinges are stainless, the sweep actually seals, and the invoice matched the phone quote to the dollar."
- Vernon H.
