Replacing windows or doors in Key West means dealing with two masters: Monroe County’s 180+ mph wind-load requirements and the Historic Architectural Review Commission’s demand that everything look like it did in 1910. We’ve done that dance on Duval Street cottages, Casa Marina villas, and just about every Conch house style in between. TruePane Windows & Doors schedules work across Key West from our South Florida metro office, and a live person answers the phone at (813) 320-9346 whenever you call. No voicemail tree, no call center, no callback form.

Why Key West Homeowners Choose TruePane Windows & Doors
Most of our Key West customers have lived in their homes for twenty or thirty years. They call us after a previous installer left them with a fogged insulated unit or a door that binds every August. That’s exactly the situation Dale Kessler founded this company to fix: out-of-true installs and voided warranties, handled permanently. The Keystone Standard puts both manufacturer warranty layers in writing before our truck leaves your driveway, and our 90-Day Done Right Promise means if it isn’t right, we make it right. No paperwork fights, no arguing about fine print.
We work regularly in Old Town and New Town, and we’re familiar with the HARC review process on historic-contributing structures. Our technicians are background-checked and uniformed. They measure every opening twice, quote manufacturer lines side by side on paper, and register warranty documentation on the spot. When a homeowner in the Meadows asks whether an impact window will pass HARC’s lite-configuration rules, the answer comes from someone who has actually pulled those permits, not from a script.
Windows & Doors Services We Offer in Key West
Window Installation
We set new-construction and retrofit windows to true, square, and plumb, with marine-grade fasteners specified for Key West’s salt air. Every opening is measured twice before any order is placed, so the unit that arrives is the unit that fits. Learn more about our Window Installation in Key West.
Door Installation
Entry doors, French doors, and interior doors all get the same treatment: hung so the reveal is even and the threshold seals tight against salt-driven rain. We quote hardware finishes side by side so you see exactly what you’re buying. Learn more about our Door Installation in Key West.
Window Replacement
Replacing old jalousie or single-hung sash with impact-rated units is the most common job we do in Key West. We handle the building permit, the HARC application when it applies, and the install in a single coordinated schedule. Learn more about our Window Replacement in Key West.
Impact Windows & Doors
We install Impact Windows & Doors - Key West systems engineered for Monroe County’s highest wind-speed zone, including laminated glass and reinforced frames from PGT and CGI. The product must meet code, but it also has to satisfy HARC’s visual requirements in historic districts, which is where most crews fall short.
Energy-Efficient Windows
Energy-Efficient Windows - Key West with Low-E coatings and argon fills make a measurable difference on a Key West electric bill, especially on west-facing walls that catch the afternoon sun. We quote Energy Star-rated lines and explain the SHGC and U-factor numbers in plain language.
Sliding & Patio Doors
Sliding & Patio Doors in Key West are a natural fit for Key West indoor-outdoor living. We set tracks level, align rollers properly, and adjust the reveal so the door glides without binding, even after the frame settles.
Glass Railing Systems
Glass Railing Systems in Key West, including frameless and semi-frameless options for decks and stairs, are fabricated and installed with the same structural care we apply to every window opening. Marine-grade fittings are standard on Key West jobs.
Custom Windows & Doors
For odd openings in historic Conch houses where nothing stock will fit, we order custom-built units matched to existing profiles, mullion widths, and divided-lite patterns. This is the work that separates a preservation-minded shop from a parts-swapper.
Neighborhoods We Serve in Key West
We cover all of Key West, but here are a few areas where we’re on the streets regularly. Typical response time for scheduling across the island is one to three business days, with a live person confirming the window by phone.

Why Key West’s Climate & Housing Affect Windows & Doors
Key West sits in Monroe County’s highest wind-speed zone, so impact-rated windows and doors must be engineered for 180+ mph design loads. But most of Old Town’s housing also falls under HARC jurisdiction, which means replacements have to visually replicate original Conch-style wood profiles, divided lites, and period hardware. No other Florida city forces a contractor to satisfy the state’s toughest hurricane-glazing code and a preservation board that will reject a modern aluminum unit because it “reads wrong” from the street in the same week.
Salt is the other constant. Being surrounded entirely by saltwater means hardware, aluminum frames, and even adhesives corrode years faster than inland. We spec marine-grade hardware and corrosion-resistant finishes on every Key West job as the baseline, not an upsell. The housing stock also matters: most older homes were built with jalousie windows, which are essentially unrated for hurricane protection. Insurance carriers increasingly refuse to cover them, which is why jalousie replacement is one of our most common calls from homeowners throughout Old Town and beyond.

FAQs About Windows & Doors in Key West
Impact window replacement in Key West typically runs $900 to $2,400 per opening for standard sizes, with larger or custom historic-profile units on the higher end. The final number depends on frame material, glass package, and whether the property is in a HARC district, which can add permit coordination time but not markup from us. Call (813) 320-9346 and we’ll give you a written, line-item quote for your actual openings.
If your home is a contributing structure within a Key West historic district, yes, you need HARC sign-off before replacing windows, even for a like-for-like impact swap. The commission reviews mullion width, lite configuration, and finish color. We pull the HARC application alongside the standard building permit so the process moves as one coordinated step, not two surprises.
Yes, and it’s one of the most common jobs we do in Key West. Jalousie louver panels are essentially unrated for hurricane protection, and many insurance carriers now refuse to cover homes that still have them. We replace them with impact-rated units that meet Monroe County code, and we handle any HARC review if the home is in a historic district.
No. We write fixed, line-item quotes before work begins, and the number you sign is the number you pay. If we find hidden rot or framing damage once the old unit comes out, we stop, show you what we found, and give you a written price for the additional scope before any work proceeds. You approve it first, in writing, every time.
Yes. We pull the building permit and the HARC application when one is required, and we close both out with inspections passed. You will not be left holding an open permit or a preservation-board violation. That’s part of the job, and we treat it that way. Call (813) 320-9346 to talk through your project.
Most single-opening replacements take one day on site once the product arrives. Product lead time varies by manufacturer and whether a custom historic-profile unit must be fabricated, which can add three to six weeks. HARC review, when it applies, can add two to four weeks to the front end. We’ll give you a written schedule at the estimate so you’re not guessing.

What Key West Customers Say
"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."
- Pat and Ray L."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."
- Gene A."Quote was the price, which after three other bids that grew legs was worth something. Double-hungs went in clean, they hauled the old ones, and the registration paperwork for the warranty came in the mail like they said."
- Dorothy K.
