Key Largo windows and doors face a set of conditions no mainland contractor ever has to think about: salt air from two directions, mandatory Miami-Dade impact ratings, and insurance carriers that will drop a policy over a jalousie window. TruePane approaches every project on the island with that reality first. We schedule crews from our South Florida office, and a live person answers the phone at (754) 238-2201 any hour you call.

Why Key Largo Homeowners Choose TruePane Windows & Doors
Most window and door companies in the Keys treat a replacement as a cash transaction. TruePane was founded by Dale Kessler in 2008 because out-of-true installs and voided warranties were problems worth fixing permanently. The company has served local communities since 2008 through a heritage of craft that started with a second-generation glazier’s rule: if the pane is not true, the job is not done.
Homeowners from Stillwright Point to the Ocean Reef area call us because we put the details in writing before the truck rolls. Both manufacturer warranty layers get registered on paper, with durations stated, before we leave the driveway. Workmanship is guaranteed for 90 days under the Done Right Promise. No paperwork fights, no arguing about what the warranty covers.
We are an authorized installer for more than a dozen manufacturer lines, including PGT, CGI, and CWS. Our technicians are background-checked and uniformed, and they quote side by side on paper so you see exactly what you are buying before you commit. Key Largo homeowners notice the difference the first time a crew measures an opening twice instead of once.

Why Key Largo’s Climate & Housing Affect Windows & Doors
Key Largo sits on a narrow coral-rock island with the Atlantic on one side and Florida Bay on the other. Every window frame, hinge, and fastener gets hit with salt from two directions at once. On the ground this means aluminum frames pit and seize, hardware corrodes, and standard builder-grade fasteners fail years before they would on the mainland. We spec stainless-steel fasteners and marine-grade finishes on every exterior opening because anything less is a callback waiting to happen.
Then there is the code. All of Monroe County sits inside Florida’s High Velocity Hurricane Zone, which means every replacement window and door must carry a Miami-Dade Notice of Acceptance rating. There is no storm-shutter workaround on most permitted work. The housing stock compounds this: a large share of Key Largo homes were built in the 1950s through the 1970s and still carry original jalousie windows. Those louvered glass units are non-impact-rated, corrode aggressively, and increasingly trigger non-renewal notices from property insurers. A significant share of our window replacement calls on the island are driven by a policy cancellation deadline, not a remodeling plan. We treat those with the urgency they deserve.
Pricing for Windows & Doors in Key Largo
Window and door pricing in Key Largo runs above mainland Florida for two reasons: impact-rated products are mandatory, and salt-air hardware requirements add cost to every opening. Expect the following ranges for standard residential work:
- Single impact-rated window replacement: $900 to $2,200 installed
- Full-home window replacement (8-12 openings): $12,000 to $35,000
- Impact-rated entry door replacement: $2,500 to $6,000
- Sliding glass door replacement (NOA-rated): $4,000 to $9,000
- Glass railing system, per linear foot: $250 to $500
These are honest Mid-Keys market ranges. Your exact quote depends on opening size, product line, and existing framing condition. Call (754) 238-2201 for a free estimate with line-item pricing in writing.

FAQs About Windows & Doors in Key Largo
Yes. All of Monroe County, including Key Largo, falls within Florida’s High Velocity Hurricane Zone, and permitted window and door replacement requires Miami-Dade Notice of Acceptance rated products. There is no workaround on most permitted work. Call (754) 238-2201 and we will walk you through exactly which product lines meet code for your specific opening.
Insurers writing policies in the Keys have started issuing non-renewal notices when inspection photos show original jalousie windows because those units are non-impact-rated and generally corroded. We see this regularly across Key Largo. Replacement with NOA-rated impact windows typically resolves the underwriting issue. Call us for a quote before your renewal deadline passes.
Most single-visit window replacements are completed in one day per opening, though full-home projects across multiple openings usually run two to five working days depending on product lead times and permitting. We will give you a written schedule before work starts.
No. TruePane quotes line-item pricing up front, and our fixed-pricing rule means no surprise line items appear on the bill. If we find rotted framing or termite damage behind an old window, we stop, show you exactly what we found, and agree on a written change order before proceeding. Call (754) 238-2201 to see how a square deal works in practice.
Yes. We pull Monroe County permits, schedule inspections, and do not consider the job complete until the county passes it. Both manufacturer warranty layers and our Done Right Promise are registered in writing before we leave the driveway.

What Key Largo Customers Say
"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."Had fog between the panes in four windows. They explained the seals had failed and argon was long gone, replaced the glass units instead of selling me whole windows. Honest outfit."
- Frank D."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.
