Fast, Reliable Window Replacement Across Key Largo

Window replacement in Key Largo is a different job than it is anywhere on the mainland. The island sits barely two miles wide, so nearly every home takes salt air from the Atlantic on one side and Florida Bay on the other, all day, every day. That double-sided exposure corrodes frames, sill pans, and hardware faster than what we see even in Miami Beach. TruePane has replaced windows and installed Sliding & Patio Doors in Key Largo on canal-front CBS cottages, elevated post-Andrew homes, and older wood-frame houses throughout the island since 2008, and every job starts with the same question: what will actually hold up to this marine environment for the next twenty years, not just the next five. If you are pricing window replacement in Key Largo, call Dale Kessler’s team at (448) 428-7290 for a free estimate and a straight answer on what your house needs.

Key takeaways:

  • Every replacement window in Key Largo must be impact-rated for Monroe County’s 170 mph wind code and marine-grade to survive double-sided salt air.
  • A typical full frame replacement in Key Largo runs $1,400 to $3,200 per opening installed, depending on the existing rough opening and water intrusion damage found once the old frame comes out.
  • Lead times on custom architectural glass, not labor availability, set the calendar on most Key Largo projects.
  • Free estimates. Written line-item quotes. Both warranty layers registered in writing before the truck leaves your driveway.

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

We have been working in Key Largo long enough to know which neighborhoods fight the salt hardest. Buttonwood Bay, Anglers Park, and the finger canal streets off Ocean Reef all have their own specific patterns of frame corrosion and seal failure, and our crews know them by sight. That is not fluff. It is the difference between a crew that knows what it is looking at when an original aluminum jalousie frame has fused to the block, and a crew that has to figure it out at your expense.

Dale Kessler founded TruePane Windows & Doors in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. We back that with a Done Right Promise and The Keystone Standard, which means both manufacturer warranty layers are registered in writing, with durations stated, before our truck leaves your driveway. No paperwork fights later. No arguing. A live person answers our phone 24 hours a day, seven days a week, and the technician who shows up at your Key Largo home will be background-checked, uniformed, and carrying a tape measure, not a sales pitch.

Scheduling and dispatch are coordinated from our Miami (South FL) office, and our crews serve Key Largo directly. Most jobs on the island are completed in a single visit. We are authorized installers for more than a dozen manufacturer lines including, PGT, and CGI, and we quote side by side on paper so you see exactly what you are paying for. That is a square deal, and it is how we have earned a strong reputation among Key Largo homeowners who intend to stay in their houses for another twenty years.

Our Window Replacement Services in Key Largo

This page covers the window replacement work we do most often in Key Largo. If you are not sure which category your project falls into, call us. We will tell you straight.

Full Frame Replacement

Full frame replacement means removing the entire existing window down to the rough opening, repairing or rebuilding the opening, and setting a new unit that is anchored properly for Monroe County wind loads. In Key Largo, full frame replacement on older CBS and wood-frame homes frequently includes removing original frames that have corroded and fused to the masonry over 40 or 50 years of salt exposure. Our crews carry core drills and build custom pressure-treated bucks on site when the opening is degraded, and we also install Glass Railing Systems in Key Largo for elevated homes needing open-view protection. A typical full frame replacement in Key Largo runs $1,400 to $3,200 per opening installed, with the higher end covering marine-grade impact units such as CGI and Andersen Coastal product lines and any bucket work or sill pan rebuild the opening requires.

Full Frame Replacement

Insert Window Replacement

Insert replacement fits a new window unit inside the existing frame when that frame is still structurally sound and square. In Key Largo, we see fewer clean insert candidates than we do on the mainland because the double-sided salt air attacks frames relentlessly. When the frame is solid and only the sash and glass are compromised, inserts are a sensible, lower-disruption option. Insert window replacement in Key Largo typically runs $850 to $1,800 per opening, depending on glass package and hardware selection. We will tell you honestly if your existing frames are not worth saving.

Insert Window Replacement

Storm Window Replacement

Storm window replacement in Key Largo is not the same conversation people have in Homestead or Cutler Bay. Here, the storm window question is rarely about removable exterior panels. It is about replacing older impact units whose seals and hardware have begun to fail after years of salt-laden southeast trades. We replace deteriorated impact windows with current Monroe County-approved assemblies that carry both the wind load rating and the marine-grade hardware the island demands. Expect $1,200 to $2,800 per opening installed for a typical replacement impact window on a Key Largo home, with the final number driven by size, glass package, and what we find once the old unit is pulled.

Storm Window Replacement

Energy-Efficient Upgrade

Energy-Efficient Windows in Key Largo focus less on heating and more on the cooling load and humidity control that define Florida Keys summers. Low-E insulated glass with argon or krypton fill, combined with properly sealed frames, cuts heat gain and keeps interior humidity manageable. Given the salt humidity attacking edge seals year-round, glass package selection here matters more than in most of Florida. A full energy-efficient upgrade on a typical 1950s or 1960s CBS home in Key Largo runs $900 to $2,200 per opening, with ROI coming from lower cooling costs and fewer seal failures over the life of the window.

We also handle Historic Window Restoration for the older wood-frame homes that line the island’s original residential streets. If your Key Largo home has original wood sash worth preserving, call us before you tear them out. Restoration is frequently cheaper than replacement and keeps the character of an older Keys cottage intact. Our Window Replacement team will assess existing sash, glazing, and counterweights, and give you a written line-item quote before anything gets ordered.

Trusted Brands We Service in Key Largo

We are authorized installers for more than a dozen manufacturer lines, and for Key Largo work we typically recommend brands that build specifically for coastal Florida: CGI, PGT, ESI, and Andersen among them. Each of these manufacturers produces marine-grade impact product lines engineered for the corrosion environment we have on the island, not just the wind load. Because we offer Es Windows service in Key Largo and service the brands we install, we keep local parts access for Key Largo customers and can get warranty work scheduled without shipping delays from out-of-state suppliers. If you are prepping for a replacement or a repair, call (448) 428-7290. We answer the phone.

Common Window Replacement Problems We See in Key Largo Homes

  • Fogging between the panes: Seal failure in low-E insulated glass is not cosmetic. Once the edge seal fails, the argon or krypton fill escapes, the glass’s insulating value collapses, and moisture permanently condenses inside the unit. In Key Largo, relentless salt humidity attacks the edge seals harder than almost anywhere in Florida, so we see this failure mode earlier and more often.
  • Corroded sill pans and threshold plates: Impact-rated windows installed without marine-grade aluminum can look fine from the street while the sill pan corrodes underneath. During a hurricane, wind-driven rain finds that corroded pan and drives water inside the wall. We replace these assemblies with true marine-grade components and pressure-tested sealant systems.
  • Frames fused to the concrete block: On older CBS and wood-frame homes throughout Key Largo, original aluminum jalousie and single-pane frames have oxidized and essentially fused to the masonry over decades. Removal requires core drilling and the fabrication of new pressure-treated bucks. This is a demolition and framing scope that mainland South Florida crews almost never need to perform.
  • Hardware that will not latch: Salt air attacks casement cranks, sliding door rollers, and multi-point lock hardware fast. In Key Largo, a window that will not close and latch is not a minor annoyance. It is an open breach in a 170 mph wind-zone building envelope, and it needs attention before June 1.

Pricing for Window Replacement in Key Largo, FL

You will see wide ranges online. Here is what we actually charge in Key Largo, as of 2026, for the work we do most. Insert replacement windows run roughly $850 to $1,800 per opening. Full frame replacements run $1,400 to $3,200 per opening. Storm and impact replacement windows run $1,200 to $2,800 per opening. Energy-efficient upgrades run $900 to $2,200 per opening. Historic wood sash restoration is quoted per sash after inspection.

What moves the number within those ranges: the size of the opening, the glass package, the frame material, the manufacturer, and what we find once the old unit comes out. In Key Largo, that last part matters more than elsewhere. Fused frames, rotted sills, and corroded pans are not rare here. They are routine. Our quotes are written line-item bids with fixed pricing. If we find hidden damage mid-job, we stop, show you exactly what we found, and agree on the change before any additional work proceeds. No surprise line items on the bill. Ever.

We also run a permanent 5% discount for seniors and veterans, a $50 credit on any repair over $250, and a maintenance check. To price your exact project, call (448) 428-7290 for a free estimate.

What Neighbors Say About TruePane Windows & Doors

★★★★★

"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."

GGene A.
★★★★★

"French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."

MMarie S.
★★★★★

"Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."

PPat and Ray L.
★★★★★

"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."

BBill T.
★★★★

"Sliding door had been dragging for years. They quoted a repair first, said the track was shot, then priced the replacement both ways on paper. No pressure either direction. Door glides with one finger now."

CCarol M.
★★★★★

"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."

RRonald P.
★★★★

"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."

VVernon H.
★★★★

"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."
