Fast, Reliable Window Replacement Across Cudjoe Key
Window replacement in Cudjoe Key, FL is not a simple swap job. Every permit on this island, even replacing one jalousie window with the same opening size, requires a Miami-Dade Notice of Acceptance or Florida Product Approval for impact resistance. That is Monroe County code, because Cudjoe Key sits entirely inside the High Velocity Hurricane Zone. TruePane Windows & Doors has worked inside those rules for years, and we know exactly what an older stilt home on Canal Street or a 1960s prefab off Spanish Main Drive turns up once the old sash comes out. Call (813) 320-9346 and we will walk you through what your specific house actually needs.
Why TruePane Windows & Doors Is Cudjoe Key’s Preferred Window Replacement Company
Dale Kessler founded TruePane in 2008 on a rule that still hangs on the shop whiteboard: if the pane is not true, the job is not done. That matters on Cudjoe Key, where a window has to hold up to salt spray off the canal on one side and Atlantic trade winds on the other. Our background-checked, uniformed technicians measure every opening twice and quote manufacturer lines side by side on paper before anything gets ordered. No one on the island should be guessing at what they are buying.
Customers on Cudjoe Key call us because a live person answers the phone 24 hours a day, seven days a week. Not a voicemail tree. Not a callback form. When a fogged seal or a frame that has oxidized through shows up three years after install, someone answers and schedules the fix. That is why homeowners choose our Window Replacement work over the mainland companies that treat the Keys as an afterthought. Dispatch and scheduling are coordinated from our Miami office, and crews serve Cudjoe Key locally, so the truck that shows up at your stilt house knows the roads and the salt environment.
We stand behind the work. Every job carries the 90-Day Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway. No paperwork fights. No arguing about what was covered.
Our Window Replacement Services in Cudjoe Key
Here is what we actually do on this island, and how each type of job works under Monroe County’s code requirements.
Full Frame Replacement
On Cudjoe Key, full frame replacement is the job code enforcement and building inspectors expect most often. Why? Because the original aluminum jamb pockets in 1960s and 70s homes have corroded through from salt spray, and because the old single-pane or jalousie units sitting in them are not legally replaceable with anything except impact-rated systems. We pull the entire old frame, re-flash the rough opening with butyl tape, set a fusion-welded impact-rated unit with marine-grade anodized frames, and call the inspector before the wall is closed. A typical full frame replacement in Cudjoe Key runs $900 to $2,400 per opening depending on size, glass package, and framing condition behind the old unit.

Insert Window Replacement
An insert replacement fits a new impact-rated sash inside the existing frame, which works when the frame itself is still sound. On canal-front lots, that is often not the case, because salt mist attacks aluminum from both sides simultaneously. We check the frame for oxidation and seal failure before recommending an insert. Inserts in Cudjoe Key typically run $650 to $1,800 per window, but we will not sell you one if the frame will not hold another decade in this environment.

Storm Window Replacement
Storm windows in Cudjoe Key are not the old aluminum triple-track units you see on mainland houses. They are code-required impact systems, laminated glass in marine-grade frames, built to take a Category 5 gust without allowing wind-born debris through the opening. We replace failed storm units, upgrade older accordion or panel systems to modern impact-rated windows, and handle the NOA paperwork that the permit office requires. Expect $1,100 to $3,200 per opening for storm-rated replacement work depending on size and manufacturer line.

Energy-Efficient Upgrade
You cannot put a non-impact efficient window on a Cudjoe Key house, but you can get both. Modern laminated impact glass with low-E coatings and argon fill cuts solar gain from the Florida sun while meeting HVHZ code. For canal-front homes, we specify marine-grade anodized frames to resist the salt. Energy-efficient impact upgrades on Cudjoe Key run $850 to $2,600 per opening depending on glass package and frame finish.

Trusted Brands We Service in Cudjoe Key
TruePane is an authorized installer for more than a dozen manufacturer lines, and on Cudjoe Key we most often quote Andersen, ES Windows, and ECO Window Systems side by side on paper so you can see the difference in glass thickness, frame material, and warranty terms before deciding. All three carry Miami-Dade NOA listings for impact products. We keep common replacement parts and hardware for these lines stocked on our service trucks, so a failed operator or a blown balance does not mean a second trip from the mainland. If you have a brand we have not listed, call (813) 320-9346 and we will tell you honestly whether it is worth repairing or replacing under Cudjoe Key conditions.
Common Window Replacement Problems We See in Cudjoe Key Homes
- Fogged panes within three years. Cudjoe Key’s salt-laden trade winds accelerate argon loss in insulated glass units that were not built with marine-grade seals. We see units with failed seals while the frames still look passable from the street.
- Frame-seal failure on non-anodized aluminum. Canal-side salt mist and Atlantic spray hit frames from opposite directions at the same time. Low-grade paint finishes oxidize and pit in two to three years on exposed elevations.
- Rotted or undersized wood framing hidden behind old jalousies. We open walls and find sill plates gone soft from moisture intrusion that started decades ago. The window was never the only problem.
- Code-triggered full replacement on 1960s and 70s prefab homes. The moment any permitted structural work is pulled, the original jalousie or single-pane aluminum windows become non-compliant and must be replaced with impact-rated units. Homeowners often discover this after the permit is already on file.
How We Handle Surprises Behind Cudjoe Key Walls
Opening up an older Cudjoe Key home is not like opening up a 2005 track house on the mainland. We have pulled a window on a 1972 stilt home off Canal Street and found the original aluminum jamb pockets corroded completely through, the result of forty-plus years of back-and-forth salt spray off the canal and the Atlantic side. The old sash came out in pieces. Behind it, the rough opening needed re-flashing with butyl tape before anything new could go in, and the framing needed localized repair before the inspector would sign off. We set a fusion-welded impact-rated double-hung with marine-grade anodized frames and argon-filled low-E glass, and brought the inspector through before we closed the wall. That is the difference between a company that has worked on Cudjoe Key and one that is guessing.
The same applies to outdated wiring or damaged framing discovered once walls are open. We inspect first, write allowances into the contract before work starts, and price any surprise in writing for your approval before we touch it. No one gets a bill for work they did not approve. That is a square deal.
Pricing for Window Replacement in Cudjoe Key, FL
Window replacement pricing in Cudjoe Key runs higher than mainland Monroe County for one simple reason: this island sits in one of the highest Exposure Category D wind corridors on the continental US, with Florida Bay to the north and open Atlantic to the south. Every unit must be impact-rated and carry a Miami-Dade NOA, and the frames need marine-grade finishes to survive the salt. A single impact-rated insert window in Cudjoe Key typically runs $650 to $1,800. A full-frame replacement with new framing, flashing, and a marine-grade anodized impact unit runs $900 to $2,400. Storm-rated replacement work starts around $1,100 and can reach $3,200 per opening for large or complex openings on canal-front elevations. Energy-efficient impact upgrades with argon-filled low-E glass run $850 to $2,600. We offer free estimates with written line-item pricing, and the quote we give is the price on the bill. Call (813) 320-9346 to schedule yours.

FAQs - Window Replacement in Cudjoe Key
Cudjoe Key is inside Monroe County’s High Velocity Hurricane Zone, where the Florida Building Code requires every window and door replacement to carry a Miami-Dade NOA or Florida Product Approval for impact resistance. Non-impact units are not a legal option under any permit here, regardless of opening size. Your permit will be denied, and installing without a permit creates a code violation that follows the property. Call (813) 320-9346 and we will help you select an impact-rated unit that fits the opening and your budget.
We inspect first, write allowances into the contract before we start, and price any surprise in writing for your approval before touching it. If we find rotted sill plates behind a jalousie window or corroded jamb pockets on a stilt home, we document it, tell you the cost, and wait for your sign-off. No one discovers a new line item on the final bill. Call (813) 320-9346 for an estimate that includes a clear allowance for frame repair.
Canal-front frames fail fast. Tidal salt mist from the canal hits one side while southeast trade-wind-driven Atlantic spray hits the other, attacking aluminum from opposite directions at once. Non-anodized or low-grade paint-finished frames can show heavy oxidation and seal failure within two to three years. We specify marine-grade anodized finishes on every canal-front job for this reason. Call (813) 320-9346 to talk about what your elevation needs.
Yes. In unincorporated Monroe County, window replacement requires a permit when the unit is being replaced, not just repaired, and every replacement must meet HVHZ impact standards. The original jalousie or single-pane aluminum units in a 1960s prefab are non-compliant the moment the permit is filed, which means the replacement must be a code-approved impact unit. We handle the permit paperwork and the NOA documentation as part of the job.
Laminated impact-rated glass is the baseline requirement. Beyond that, we recommend argon-filled low-E insulated units to manage solar gain and reduce cooling loads, with marine-grade anodized frames for salt resistance. High-performance laminated units with low-E coatings meet both the impact code and the energy-efficiency targets many homeowners want. Call (813) 320-9346 and we will put side-by-side quotes in front of you so you can see the glass specifications and warranty durations in writing.
