Fast, Reliable Custom Windows & Doors Across Key West
Custom windows and doors in Key West fall under two sets of rules most Florida contractors never have to face at once: HVHZ Miami-Dade NOA wind-load certification and the Historic Architectural Review Commission’s aesthetic standards for Old Town. Get either one wrong and the work gets torn out. We handle both, filing the HARC submittal ourselves and ordering nothing until the commission stamps the drawings. Call Dale Kessler and the TruePane team at (754) 238-2201 for a free estimate on replacement windows, custom doors, or full jalousie tear-outs anywhere from Bahama Village to Casa Marina.
Why TruePane Windows & Doors Is Key West’s Preferred Custom Windows & Doors Company
Key West homeowners deal with a combination of salt air, hurricane wind loads, and a preservation board that reviews window muntins like a thesis committee. We have spent years working inside that system, and we know which manufacturer lines get approved on the first submittal and which ones HARC sends back. Our Custom Windows & Doors team carries that knowledge onto every job site, from New Town ranchers to 19th-century Conch houses on William and Eaton Streets.
We show up when we say we will. We measure every opening twice. And we register both manufacturer warranty layers in writing before the truck leaves your driveway, because the Keystone Standard is not a slogan here. It is the reason homeowners from Truman Annex to Midtown call us when a previous contractor left them with a fogged seal and a HARC violation notice on the front door.
We also understand what living on an island does to a schedule. Dispatch and scheduling are coordinated from our Miami office, and our crews work Key West jobs on a planned rotation. When you call, a live person answers. Not a voicemail tree, not a callback form. If we tell you a team will be on-island Tuesday, they are on-island Tuesday.
Our Custom Windows & Doors Services in Key West
Architectural Grilles & SDLs
Old Town Key West homes lived most of their lives with true divided-light wood windows, and HARC will not accept a flat SDL stick-on grid that looks like an afterthought. Our team installs simulated divided lites with a profile that matches the original two-over-two or six-over-six patterns, in frame colors the commission has already reviewed. For a 1912 Conch house on William Street, we replaced 14 jalousie windows with HVHZ-certified double-hung impact units that replicated the original two-over-two divided-light pattern in white aluminum after securing HARC pre-approval on the muntin profile. No re-dos, no removals, no commission surprises.

Custom Shape Windows
Transom lights, eyebrow windows, and half-rounds are not decorative afterthoughts in Key West. They are part of the historic envelope, and they still need to meet HVHZ wind-load certification. We source radius and custom-angle impact glass from manufacturers who have already passed Miami-Dade NOA testing for shaped units. That matters because a custom-shaped window that is not NOA-listed will get bounced by the building department, no matter how well it matches the original opening. Expect $1,600-$4,200 per custom-shaped impact window in Key West, depending on glass area and frame material.

Oversized Glass Panels
Homes on the Atlantic side of Key West often feature wide picture openings looking toward the water, and those openings test every limit in the HVHZ code. A 10-foot-wide impact-rated panel is not something you order from a catalog. We engineer the glass thickness, frame reinforcement, and mullion capacity before we ever quote the job, so the number we give you is the number you pay. Oversized impact panels in Key West typically run $90-$160 per square foot installed, with the labor weighted by crane access and second-floor work.

Commercial Storefront Glazing
Duval Street storefronts, gallery spaces near Greene Street, and restaurant entryways all need glazing that survives both hurricane season and daily tourist traffic. We install code-compliant impact storefront systems with proper drainage and corrosion-resistant hardware, because standard commercial aluminum will pit in Key West’s salt air faster than it would in Miami. We also handle code-drive retrofits when a property changes use and the existing glazing no longer meets current wind-load requirements.

Trusted Brands We Service in Key West
We are an authorized installer for more than a dozen manufacturer lines, and in Key West we lean heavily on PGT, CGI, and Ply Gem for their HVHZ product catalogs and HARC-friendly frame profiles. Being authorized matters for you in two ways. First, the warranty paperwork is real and registered in writing. Second, we can pull side-by-side quotes on paper so you see exactly what a PGT impact unit costs next to a CGI unit, with the glass package, frame finish, and hardware specified line by line. No hiding behind a single brand and a vague “trust us” price.
Common Custom Windows & Doors Problems We See in Key West Homes
- Jalousie windows that cannot be made hurricane-rated. The louvered glass you have been living with since 1965 leaks air, lets salt in, and fails every impact standard. Replacement means a full tear-out and HARC-reviewed impact units. We file the submittal first and fabricate after approval.
- Marine corrosion on hardware and weatherstripping. Key West is surrounded by saltwater with no inland buffer. Standard coastal-grade hardware pits within two years, the sash binds, and the seal fails. We specify corrosion-resistant hardware on every island job, because the wrong hinge choice costs more than the window itself down the road.
- HARC reversal after installation. We have seen permitted impact windows removed because the muntin profile was wrong or the frame color was bronze instead of white. That is a multi-thousand-dollar mistake. Pre-approval is a standard line item in every Old Town contract we write.
- Houses torn open while the commission deliberates. Some contractors order windows before HARC review concludes, then the commission requests a design revision and the house sits with plywood over the openings for three extra weeks. We schedule fabrication after the stamp, not before.
Pricing for Custom Windows & Doors in Key West, FL
Let’s get to the numbers. A standard HVHZ-certified impact single-hung or double-hung in Key West runs $1,100-$2,400 installed per window, but Old Town HARC-reviewed work with custom muntins and frame colors adds 15-30 percent on top of that. Custom-shaped impact windows run $1,600-$4,200 each. Oversized glass panels add $90-$160 per square foot. Full Conch house jalousie replacements typically land between $18,000 and $45,000 for a 12-20 opening home, depending on the complexity of the HARC submittal and the muntin detail. The free estimate we give you is a written line-item quote. The number we put on paper is the number you pay, unless you change the scope.

FAQs - Custom Windows & Doors in Key West
No. HARC wants the replacement unit to reference the original proportions and divided-light pattern, not replicate the jalousie louver mechanically. A two-over-two double-hung in white aluminum with a true divided-light muntin profile typically passes review on the first submittal, even when the original house had louvered glass. What gets refused is a flat SDL grid or a bronze frame on a house HARC considers historically white. We file the submittal with drawings and product photos before you spend a dime on fabrication. For a specific ruling on your block, call (754) 238-2201 and we will walk you through what has passed in your immediate neighborhood.
Three to six weeks is the honest range on top of the build time for the windows themselves. The commission meets on a fixed calendar, and a submittal that misses the agenda cutoff sits until the next cycle. That is why we file early, pre-approve the muntin profile and frame color, and only then release the fabrication order. On the William Street Conch house job, the review added exactly three weeks, and because we did not cut a single pane of glass before the stamp came down, the install took five days once the units landed. Call (754) 238-2201 for a schedule tied to your HARC cycle.
Yes, if the manufacturer has already run Miami-Dade NOA testing on that exact shape and glass configuration. A half-round or arched transom that is not NOA-listed will fail plan review, no matter how well it matches the original opening. We source custom shapes from manufacturers with existing NOA listings, then we verify the engineering before we quote. Expect $1,600-$4,200 per shaped impact window in Key West depending on area and frame material. Call (754) 238-2201 and we will check your exact opening against the NOA catalog.
Standard coastal-grade aluminum hardware on hinges, locks, and weatherstripping is the biggest corrosion risk. The constant salt spray from being surrounded by ocean on all sides pits the metal, the sash binds, and within two years you are fighting a window that will not close. We specify corrosion-resistant hardware on every Key West job and include it on the line-item quote, because the cost of the right hinge is a rounding error compared to a service call for a window that will not settle into the frame. For a hardware audit on your existing windows, call (754) 238-2201.
No. A fogged insulated glass unit means the seal has failed, and once the seal is gone the argon or krypton fill escapes. The window loses its thermal performance, the glass faces begin to degrade from salt and moisture infiltration, and eventually you are paying to condition air that leaks straight through the dead unit. In Key West’s humidity, a failed seal also invites mold between the lites. It is a replacement, not a cleaning. Call (754) 238-2201 for an exact quote on the replacement unit. Estimates are free.
