Impact Windows & Doors in Key Largo - Free In-Home Measure, Written Price

Fast, Reliable Impact Windows & Doors Across Key Largo

Impact windows and doors in Key Largo, FL typically run $1,100-$3,400 per opening installed, with our Sliding & Patio Doors in Key Largo run $3,500-$8,500 depending on size, marine-grade hardware, and the condition of your existing openings. Most whole-home replacements on the island take 2-4 days once materials arrive, but the fuse comes first: salt. If you’re reading this from a 1960s concrete block cottage on Blackwater Sound or a post-Andrew elevated home on a finger canal off Pirate’s Cove, you already know the battle. Our crews work Key Largo weekly from our dispatch office in Miami, and we stock marine-grade framing hardware, 316 stainless fasteners, and hot-dip galvanized sill pans specifically because standard impact units corrode measurably faster here than just 20 miles north. Call (448) 428-7290 for a free estimate, and we’ll price your openings against what the salt air actually demands, not what a mainland spec sheet promises.

Why TruePane Windows & Doors Is Key Largo’s Preferred Impact Windows & Doors Company

Key Largo homeowners tend to be past the point of optimism about contractor promises. They’ve either watched a neighbor’s “hurricane-rated” window pit and seize within five years, or they’ve spent a Saturday morning trying to open an aluminum slider that salt welded shut sometime around 2019. That’s the customer we built TruePane for. We’re led by Dale Kessler, a second-generation glazier who founded the company in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. Key Largo’s marine environment makes that rule matter more than almost anywhere in Florida.

Our reputation on the island was built the slow way, job by job. We work canal-front homes along Tarpon Basin, Tavernier Creek side streets, and the older CBS cottages clustered around US-1 from the 905 split down to the Card Sound Road turnoff. Our customers call us because we answer the phone. A live person, 24 hours a day, 7 days a week. Not a voicemail tree. Not a callback form. If you have a leaking impact unit after a squall line rolls through, you call (448) 428-7290 and someone picks up.

We measure every opening twice. We quote manufacturer lines side by side on paper, so you see the difference between a PGT marine-spec frame and a mainland aluminum before you spend a dollar. And we register both warranty layers in writing before the truck leaves your driveway. That’s The Keystone Standard. It’s not a slogan. It’s what we’d want for our own mothers’ houses on Plantation Key.

The Done Right Promise

Every job carries a Done Right Promise. If something isn’t right, we come back and fix it. No paperwork fight. No arguing. No fine print that covers neither. TruePane has served local communities since 2008 through Dale’s craft heritage, and we plan to be answering the phone in Monroe County thirty years from now. That changes how we frame, flash, and seal every opening on a Key Largo home. We stand behind it.

What To Expect When We Come to Key Largo

• Background-checked, uniformed technicians who work like they’re in their own mother’s house.
• Written, line-item quotes before any work starts. A square deal, no surprise line items on the bill.
• Both manufacturer warranty layers registered in writing, with durations stated, before we leave the driveway.
• Marine-grade fasteners and flashing specified as standard on Key Largo jobs, because standard doesn’t survive here.

Our Impact Windows & Doors Services in Key Largo

We install, replace, and service Impact Windows & Doors with the understanding that Key Largo’s two-ocean salt attack changes the material conversation entirely. Here’s how that plays out across the services our Key Largo customers call about most.

Hurricane Impact Windows

Replacement impact windows in Key Largo are the single highest-value upgrade a homeowner here can make, because the island’s original 1950s-70s aluminum jalousie and single-pane sliders were never designed for a 170 mph wind zone. Most of the concrete block stucco homes we replace on the bay side are still carrying windows that bow inward under tropical storm gusts. We specify marine-grade frames with hot-dip galvanized sill pans and 316 stainless hardware as standard, because the trade winds off Florida Bay will pit a standard aluminum frame at the jambs within three to five years. A typical double-hung impact replacement in Key Largo runs $1,200-$2,400 per opening installed, depending on size and whether we’re dealing with a fused old frame. More on that in a minute.

Impact Sliding Glass Doors

Canal-front homes along Tarpon Basin Drive, Sunset Road, and the finger canals off Pirate’s Cove often have our Glass Railing Systems in Key Largo neighbors with sliding glass doors on two or even three facades. Every one of those facades catches salt-laden wind from a different direction. Impact sliding glass doors in Key Largo generally run $3,500-$8,500 installed, with the difference driven by panel size, whether the existing track has corroded into the slab, and whether we need to rebuild the threshold completely. We use marine-grade tracks, rollers, and hardware that won’t seize up after two seasons of salt fog. And we seal the perimeter so wind-driven rain at 130+ mph can’t find its way behind the frame and into your subfloor. Because once that happens, you’re not replacing a door. You’re gutting drywall.

Impact Entry & French Doors

Front entry doors in Key Largo take abuse from the Atlantic side. French doors facing the water take it from the Bay side. We install impact-rated entry and French door systems with stainless hinges, sealed thresholds, and frames that won’t oxidize and bind in July humidity. A typical impact entry door replacement on the island runs $2,200-$5,000, depending on glass lite configuration and whether we’re dealing with wood-frame or CBS construction. The older wood-frame homes, especially north of the Tavernier Creek bridge, often need the rough opening rebuilt before a new impact door can be properly anchored. We include that in the written quote. Not as an add-on later.

Impact Garage Doors

Garage doors are the biggest unbraced opening on almost every Key Largo home. In a hurricane, a failed garage door pressurizes the house and lifts the roof. Monroe County code requires impact-rated or braced garage doors in new construction and most replacements. We install impact garage doors rated for the 170 mph exposure categories common on the island’s exposed coastal lots. Prices typically run $2,500-$6,500 depending on size, tracking, and whether your current tracks are still square after decades of humidity and salt exposure.

Wind Mitigation & Code Compliance

Every window and door we install in Key Largo is engineered to meet current Florida Building Code and Monroe County wind design speeds, which approach 170 mph in exposed coastal categories. We pull permits, schedule inspections, and document the installation so your wind mitigation report stands up when your insurance company asks. Dale’s crew has been doing code-compliant impact work since before impact work was cool. If you’re buying a 1950s CBS cottage with original jalousies, we’ll tell you honestly which openings fail first under code, and which ones can be phased over time.

Trusted Brands We Service in Key Largo

We’re an authorized installer for more than a dozen manufacturer lines, and in Key Largo we quote side by side so you can see which brand’s marine-spec offerings actually hold up. For this market, we frequently quote PGT and Cgi repair in Key Largo because both manufacture frames and hardware engineered for Florida’s coastal exposure categories, and we’ve seen their marine-spec lines hold up on bay-front installs where mainland aluminum pits in three years. We also work with Ply Gem on openings where budget matters and the house sits back from the water. Parts for these lines are stocked at our South Florida dispatch, which means when a Key Largo customer calls about a fogged seal or a seized roller, we’re not waiting two weeks on a freight shipment. Call (448) 428-7290 and ask us to price your openings across the brands we trust on this island specifically.

Common Impact Windows & Doors Problems We See in Key Largo Homes

This is the list we actually work from when a Key Largo homeowner calls. None of it is theoretical.

• Fused aluminum frames on 1950s-70s CBS cottages. We pulled jalousie frames from a 1962 CBS home on Tarpon Basin Drive where salt had welded the original aluminum into the concrete openings. Core drilling and pressure-treated bucks were required before any new unit could be anchored. If your windows haven’t been opened in a decade, assume the frames are fused.
• Standard impact frames pitting at the jambs within 3-5 years. The same homeowner had already lost two standard impact units to pitting within six years on the bay side. Key Largo’s two-directional salt fog is the culprit. Standard aluminum frames simply don’t hold up here, regardless of what the impact rating sticker says.
• Perimeter seal failures on canal-front homes. Wind-driven rain at 130+ mph finds the weakest perimeter seal on an impact unit and drives water inside. If you’ve got drywall staining or soft subfloor near sliding glass doors on a finger canal home, the seal is likely compromised. This isn’t a window problem alone. It’s a water intrusion problem with a window-shaped entry point.
• Corroded threshold plates and door hinges on ocean-side entries. Atlantic-facing entry doors take constant salt spray during the trade wind season. Hinges seize. Thresholds oxidize. The door itself might be fine, but the hardware around it has failed. We replace with 316 stainless and marine-grade seals, not the zinc-plated hardware that came off.

Why Salt Decides Everything on This Island

Key Largo is roughly two miles wide at its widest, with salt-laden trade winds hitting homes simultaneously from the Atlantic and Florida Bay. That means virtually every window and door on the island is a marine-corrosion test rig that Custom Windows & Doors in Key Largo must be built to withstand, unlike inland impact products never designed to pass. A standard impact-rated aluminum frame might survive twenty years in Homestead. The same frame on a canal-front lot off Grouper Creek can show measurable pitting at the jambs within three. The defining business reality for every job on this island is a dual demand: the product must be impact-rated for Monroe County’s 170 mph wind zone, and it must also be marine-grade in its framing, hardware, sill pans, and seals. Standard impact products corrode measurably faster here than on the mainland. That’s the truth, and it’s why we won’t quote you a Homestead-spec window for a Key Largo opening even if you ask.

The older canal-front CBS homes are the worst case. Many still have original aluminum jalousie or single-pane sliders whose frames have corroded and essentially fused to the masonry over 40-50 years of salt exposure. Replacement crews regularly need core drills and custom pressure-treated bucks to extract fused frames before a new Monroe County-approved impact unit can be properly anchored. That’s a demolition and framing scope that mainland South Florida jobs almost never require, and it’s a line item you want on the written quote up front, not discovered halfway through the day. We include it. We’ve done too many of these extractions not to know what’s behind the stucco.

The Price Gap: Coastal-Spec vs. Inland-Spec

A marine-grade impact window in Key Largo runs roughly 25-40% more in materials than the same model spec’d for inland Miami-Dade. The difference is in 316 stainless hardware instead of zinc-plated, hot-dip galvanized sill pans instead of raw aluminum, and a frame finish engineered for salt fog rather than standard architectural coating. The cheap spec looks identical on paper. It also fails within a decade: pitted frames, seized rollers, corroded thresholds. You’ll pay for the cheap window twice. The marine spec costs more on the front end and it’s still doing its job when the cheap one is in a landfill. Call (448) 428-7290 and we’ll show you the exact material difference on a written quote, side by side, with both prices. That’s the only way to make an honest decision.
