AfterFast, Reliable Custom Windows & Doors Across Key Largo
Custom window and door work in Key Largo is a different trade than it is on the mainland. The island runs roughly two miles wide at most, with the Atlantic on one side and Florida Bay on the other, so nearly every home gets salt air from two directions at once. That changes which materials hold up, which frames survive, and how a removal job actually goes once we open the wall. TruePane handles it with marine-grade components, Monroe County permit work, and crews who know the difference between a standard impact install and one that will still be square in twenty years. Call (448) 428-7290 to schedule a free estimate for Custom Windows & Doors.
Why TruePane Windows & Doors Is Key Largo’s Preferred Custom Windows & Doors Company
We have been doing custom window and door work on this island long enough to know what fails here and why. The corrosion pattern on a canal-front CBS cottage off Port Largo is not the same as a stilt home on Tarpon Basin, and we plan the job accordingly. Customers in Key Largo call us because our technicians show up in uniform, measure every opening twice, and put the quote on paper side by side across manufacturer lines: PGT in Key Largo, CGI, CWS, and the others we carry. No verbal numbers, no change-order surprises later.
When a Key Largo homeowner calls with a fogged impact unit or a patio door that binds in July humidity, a live person answers - whether you need Impact Windows & Doors in Key Largo or routine service. Not a voicemail tree, not a callback form. We coordinate scheduling from our South Florida office and have crews serving Key Largo directly, which means your estimate is booked around your schedule, not a regional dispatch board. Every job carries the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing before our truck leaves your driveway. We stand behind it. That is the whole point.
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. We hire local, train apprentices into journeymen, and act like a company that plans to be in town in thirty years. That matters in Key Largo, where the salt air does not forgive shortcuts and the next hurricane season is always coming.
Our Custom Windows & Doors Services in Key Largo
Custom Shape Windows
Key Largo homes rarely want a plain rectangle in every opening. Arched transoms over canal-facing living rooms, trapezoid clerestory windows on stilt homes, and radius bays on newer waterfront builds all call for custom shape work. We fabricate to the exact rough opening dimensions, and we specify marine-grade frames and stainless hardware from the start because a custom radius window on the bayside gets the same two-front salt spray as everything else. If the shape is unusual, the frame still has to survive, not just look right.
Commercial Storefront Glazing
Storefronts along Overseas Highway in Key Largo take a beating from sun, salt, and wind-driven rain; and a compromised storefront system leaks into your retail space long before the glass itself breaks. We handle commercial storefront glazing for shops, offices, and restaurants along the island, with impact-rated and marine-grade assemblies that meet Monroe County wind design speeds approaching 170 mph. We schedule around business hours where possible and keep the work area safe for foot traffic.
Curtain Wall Systems
For larger residential or commercial elevations, curtain wall systems carry a bigger engineering load in Key Largo than they would in Homestead. The wind pressure calculations in Monroe County’s exposed coastal categories push designers toward heavier mullions, deeper anchors, and marine-grade pressure plates. We work with your architect or engineer to make sure the curtain wall spec is not just impact-rated, but corrosion-rated for the island. A mainland curtain wall spec brought here will pit and bind within a few years. We will not install it that way.
Architectural Grilles & SDLs
Simulated divided lites and architectural grilles give a Key Largo home the look of divided-light windows without sacrificing the impact rating. We install SDLs inside and outside the insulated glass unit depending on the product line, and we recommend exterior grilles on marine-grade frames that can take the salt without oxidizing. The grille pattern is chosen to match the home’s architecture, whether that means 1950s CBS cottage lines or a modern elevated build.

Trusted Brands We Service in Key Largo
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. For Key Largo Window Replacement specifically, we lean on PGT, CGI, and CWS because those product lines have marine-grade and high-velocity hurricane options that actually hold up on this island. We keep common replacement hardware and glazing seals in local stock so turnaround on warranty parts does not stretch into weeks. We quote lines side by side on paper so you see exactly what each manufacturer offers, with both warranty layers registered before we leave.
Common Custom Windows & Doors Problems We See in Key Largo Homes
- Fused aluminum jalousie frames: Original jalousie or single-pane aluminum slider frames on 1950s to 70s CBS cottages corrode and seize to the masonry after 40 to 50 years of salt exposure. Removing them is demolition work, not a simple swap, and it often requires core drills and custom pressure-treated bucks before new anchors go in.
- Fogged insulated glass from salt-damaged seals: Impact glazing with standard aluminum frames pits and loses perimeter seal integrity within a few years from two-front salt spray. Once argon fill leaks out, the unit fogs, and the only real fix is replacement of the glass pack or the full sash.
- Failed perimeter flashing on non-marine assemblies: We regularly see windows and doors where the glass itself is impact-rated, but the sill pan or flashing was not marine-grade. Wind-driven rain at hurricane velocities penetrates those weak points even when the glass holds, and the damage shows up as mold inside the wall or water stains at the baseboard months later.
- Undersized framing behind large openings: Post-Andrew stilt homes and the big glass elevations on modern canal-front builds sometimes sit on headers or king studs that were not sized for today’s wind-load tables. Once we open the wall for a window replacement, the permit inspection can flag that framing, and the job scope expands. We plan for it beforehand, not after the drywall is off.
Pricing for Custom Windows & Doors in Key Largo, FL
Custom window and door pricing on Key Largo runs higher than mainland South Florida for reasons that are honest and measurable: marine-grade frames, stainless hardware, pressure-tested flashing assemblies, Monroe County permit fees, and the demolition scope when old frames have fused to the block. A single custom-shaped impact window in Key Largo with marine-grade frame and hardware typically runs $1,800 to $4,200 installed, depending on size, shape, and whether reframing is required. Oversized glass panels on a canal-front home run $4,500 to $12,000 per opening when engineering, lifting, and anchoring are included. Architectural grilles and SDL options add $250 to $900 per window depending on pattern and whether the grid sits inside or outside the glazing unit. Curtain wall work is quoted per project, not per panel. Our estimates are free, written, and line-itemed before any work begins, so you will not get a phone call about an “unforeseen condition” that should have been caught at the first measure. Call (448) 428-7290 for an exact quote on your Key Largo home.

FAQs - Custom Windows & Doors in Key Largo
Because the Florida Building Code sets impact and wind-load standards, but it does not address the corrosion rate of a two-mile-wide island where the Atlantic and Florida Bay salt air hit nearly every facade from two directions simultaneously. Standard impact-rated aluminum frames, hardware, and seals corrode measurably faster in Key Largo than in Homestead or Miami, and the failure shows up as pitted frames, seized hardware, and fogged glass within a few years. Marine-grade frames, stainless steel hardware, and pressure-tested flashing assemblies are the only way to make an impact unit survive here beyond a single hurricane season cycle. Call (448) 428-7290 and we will spec the right assembly for your home’s exposure.
The removal becomes a controlled demolition job, and that is the honest answer. After 40 to 50 years of salt exposure, aluminum jalousie frames corrode into the masonry, and they do not pull out cleanly. Our crews use core drills to break the frame free, then set a custom pressure-treated buck into the opening before anchoring the new Monroe County-approved impact unit - standard procedure for any Key Largo Door Installation we handle. You should also expect the permit inspection to look at the framing behind the opening, because on older Key Largo homes, the structure was not always sized for today’s 170 mph wind-load tables. We scope the reframe and write it into the contract before we touch anything. Call (448) 428-7290 for a site measure and a written line-item quote.
Usually yes, as long as the replacement unit meets current impact and wind-load requirements for Monroe County and the existing framing passes inspection. What triggers a broader upgrade is when the inspector sees framing that is undersized or deteriorated, or when the original rough opening was never flashed correctly. That is where the job can expand, and the honest approach is to plan for that possibility in the estimate rather than hit you with it after demolition. We write allowances and pricing into the contract up front. Call (448) 428-7290 and we will walk you through what to expect on your specific opening.
If you see persistent fogging between the panes, moisture or mineral staining on the interior glass surfaces, or the glass develops a cloudy film you cannot clean off, the seal has failed and the insulating gas has leaked out. In Key Largo, the cause is almost always salt-driven oxidation of the perimeter seal or the aluminum spacer. Once the seal goes, the unit loses thermal and acoustic performance, and the only lasting repair is a full replacement of the glass pack or sash. Call (448) 428-7290 and we will inspect the units and give you a written recommendation.
Yes. Oversized glass panels on a canal-front Key Largo home carry a much larger wind-load surface, and the anchoring has to transfer that load into the structure without failing under repeated hurricane cycling. We work with an engineer to size the anchors, mullions, and header reinforcement correctly for Monroe County’s exposed coastal wind speeds. It is not a standard-size install with a bigger piece of glass; it is a structural opening that has to survive a 130 mph-plus wind event with storm surge spray hitting the corners. Call (448) 428-7290 to schedule a structural review with our crew.
