Why TruePane Windows & Doors Is Big Pine Key’s Preferred Impact Windows & Doors Company
Big Pine Key homeowners have been calling us since well before Hurricane Irma reshaped this island in 2017. The post-storm rebuild taught us something most mainland contractors still haven’t learned: on a narrow island with salt air on both sides of US-1, the difference between a good window job and a bad one shows up in the fasteners and flashing, not the glass. We use stainless or hot-dipped galvanized hardware on every opening. It costs a little more up front and saves a seized jamb or corroded sash in five years.
We dispatch locally to Big Pine Key from our South Florida office, which means a live person answers when you call, and you’re not routed through a regional call center. Our background-checked, uniformed technicians measure every opening twice. Both manufacturer warranty layers get registered in writing before the crew leaves your driveway. That’s The Keystone Standard, and it’s non-negotiable on every job we run from Marathon down to Big Pine Key.
Dale Kessler founded TruePane in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. That’s not a slogan. It’s how we train apprentices into journeymen and why we plan to be on this island in thirty years.
Our Impact Windows & Doors Services in Big Pine Key
Hurricane Impact Windows
Replacing original single-pane sliders and jalousie windows on Big Pine Key stilt homes is the work we do most. Older openings on pilings almost never meet the current Florida Building Code wind-load provisions for 150+ mph design speeds. We install impact-rated units from Andersen, Pella, and Marvin, with marine-grade hardware and flashing tape at every rough opening. Each replacement gets permitted through Monroe County and inspected before your insurer sees the documentation.

Impact Sliding Glass Doors
Impact-rated sliding glass doors on Big Pine Key take a beating from the salt air. Frames and roller hardware made for mainland conditions seize within a few years here if they’re not stainless. We pull old sliders on homes in Eden Pines Colony and elsewhere on the island, reframe undersized headers where the original construction cut corners, and install impact sliders built for 150+ mph wind loads. A typical impact slider for a Big Pine Key home runs $4,500-$9,000 installed, depending on width and finish.

Impact Entry & French Doors
Front entry doors on Big Pine Key face the same wind-load code that windows do, and many pre-Irma doors don’t come close. We install impact-rated entry and French doors that meet Monroe County requirements, with corrosion-resistant hinges and thresholds sized for elevated stilt construction. Expect $3,800-$8,500 for a standard impact entry door, installed and permitted.

Impact Garage Doors
Garage doors on Big Pine Key are often the weakest opening on the house. Wind-rated garage doors with reinforced tracks and bracing run $3,200-$7,000 installed on this island. If your insurer has flagged the garage opening, we document the upgrade the same way we do windows: permit, install, inspection, paperwork in your hand.

Common Impact Windows & Doors Problems We See in Big Pine Key Homes
- Corroded aluminum frames and seized jamb hardware. Salt-laden air from the Atlantic and Gulf sides of US-1 accelerates corrosion on non-marine-grade parts. We see sash locks and roller assemblies fail within three to five years on hardware built for mainland Florida.
- Original jalousie windows on pre-Irma stilt homes. These openings were never designed for 150+ mph wind loads. Insurers writing policies in Monroe County are actively requiring replacements before renewal, especially in subdivisions like Eden Pines Colony where many homes structurally survived Irma but kept their original windows.
- Undersized headers and missing king studs. Once we pull an old window or slider on a 1970s-90s stilt home, the framing rarely matches today’s code. This is the single biggest reason a replacement quote moves, and it’s why we inspect before we quote a final number.
- Failed waterproofing around old rough openings. Wind-driven rain penetrates where the original flashing has rotted or was never installed correctly. We find plywood bucks and sill plates that need replacement only after the original window comes out. That’s a hidden condition we document, price, and get written approval on before touching the structure.

FAQs - Impact Windows & Doors in Big Pine Key
Yes. Every impact-rated window replacement in Big Pine Key requires a Monroe County permit, and the permit triggers an inspection. What surprises most homeowners is what the inspection finds: once the old jalousie comes out, the current Florida Building Code requires the rough opening to meet 150+ mph wind-load standards. That often means undersized headers get upgraded, missing king studs get added, and waterproofing gets corrected. We price these as written allowances in the estimate and get approval before any framing work starts. Call (813) 320-9346 to have us inspect your openings before you commit to a number.
Big Pine Key sits on a narrow island with open water on both sides, so the air carries salt year-round. Aluminum frames, roller assemblies, and fasteners made for mainland conditions fail within a few years here. The fix is marine-grade materials at install: stainless or hot-dipped galvanized fasteners, corrosion-resistant hardware, and flashing tape at every rough opening. If you already have impact windows with seized hardware, we can replace the hardware without pulling the frame in most cases. Call (813) 320-9346 for an assessment.
Yes. This is a steady part of our work on Big Pine Key. After install and inspection, we provide the permit record, the inspection result, and both manufacturer warranty layers registered in writing. Insurers in Monroe County accept this documentation, and we have walked many Eden Pines Colony homeowners through the exact renewal process. Call (813) 320-9346 and we’ll start with a free estimate and the paperwork trail your carrier needs.
We inspect first and write framing allowances into the contract before we start. If we open the wall and find rotted sill plates, undersized headers, or missing king studs, we give you a written change order with the exact cost and get your approval before touching the structure. You never get a surprise line item at the end. This is how we’ve handled every Big Pine Key job since Irma, because virtually every pre-2017 stilt home has at least one opening that won’t pass current code. Call (813) 320-9346 to have us inspect before you commit.
Impact-rated glazing means the window itself is built to take a Category 4 wind load and debris strike without failing, with no action required from you when a storm is coming. Shutters are a separate layer that must be deployed before the storm, and they protect only when installed. Many Big Pine Key homeowners who rebuilt after Irma chose impact windows because insurers prefer the passive protection and the documentation trail is simpler. We install both, and we’ll quote them side by side so you can compare. Call (813) 320-9346 for pricing on your specific openings.
