AfterFast, Reliable Impact Windows & Doors Across Key West
Impact windows and doors in Key West have to do two jobs that fight each other: stop a 180 mph storm and disappear into a 1920s Conch cottage. That’s the problem most window companies won’t tell you about, and it’s the reason we get called after the other bid gets rejected by HARC. TruePane Windows & Doors installs Impact Windows & Doors that clear Monroe County’s wind-load code and pass the Historic Architectural Review Commission’s street view on the first submission. If you’re pricing impact windows in Key West, call (813) 320-9346 for a written quote that shows both compliance layers before you sign anything.
Why TruePane Windows & Doors Is Key West’s Preferred Impact Windows & Doors Company
We’ve worked enough Old Town jobs to know the HARC permit is not optional paperwork. It’s the first thing we pull, alongside the standard building permit, because a stop-work order on a contributing Conch house costs weeks and a reorder. Our crews arrive in uniform, background-checked, and they measure every opening twice before ordering. That second measurement has saved Key West homeowners from misordered double-hung units more times than we can count, especially on wood-framed homes where nothing is square after ninety years of settling.
Dale Kessler founded this company in 2008 on a rule he still keeps on the whiteboard: if the pane is not true, the job is not done. That’s the standard behind our work in Key West, from Truman Annex to Bahama Village to the Casa Marina district. We’re not a franchise operation that flies a crew in for a season. We’ve served South Florida’s coastal communities since 2008, and a live person answers our phone 24 hours a day, seven days a week. Key West homeowners don’t get a callback form.
Our Impact Windows & Doors Services in Key West
Hurricane Impact Windows
We replace jalousie, single-hung wood sash, and failed impact units with windows rated for Monroe County’s 180+ mph design loads. For Old Town contributing structures, we spec wood-clad profiles from ViewLux or Andersen with divided lites that match the original mullion pattern HARC has on file. On newer construction outside the historic district, we quote aluminum and vinyl impact lines side by side on paper so you see exactly what you’re buying.
Impact Sliding Glass Doors
Sliding glass doors facing the water take salt spray and wind-driven rain year-round, not just during storms. In Key West, we order marine-grade stainless rollers and corrosion-resistant track systems as the baseline, not an upgrade. A standard inland track will seize within two years on a canal-facing home in Key Haven or a condominium off South Roosevelt Boulevard.
Impact Entry & French Doors
A French door on a Conch house is not just an opening; it’s the street-facing character of the building. HARC reviews the stile width, the lite pattern, and the finish color. We quote Marvin and Pella French doors with impact glazing and wood-clad exteriors that hold up to the salt air while reading correctly from Duval Street. Door hardware gets the same marine-grade treatment as the windows.
Impact Garage Doors
Garage doors are the most common wind-borne debris failure point in Key West homes. We install impact-rated garage doors with reinforced tracks and hurricane bracing that meet Monroe County’s wind-load requirements. For homes in flood zones, we check the door’s pressure rating against your elevation certificate so the compliance paperwork lines up for your insurer.

Trusted Brands We Service in Key West
We’re an authorized installer for more than a dozen manufacturer lines, and we bring the ones that matter in Key West’s salt air: ViewLux for historic-profile impact windows, Andersen and Pella for wood-clad double-hung units, and PGT and CGI for high-wind aluminum and vinyl. Every job we quote includes both manufacturer warranty layers registered in writing before the truck leaves your driveway. That’s our Keystone Standard. If a warranty claim ever comes up, the paperwork’s already done and the duration’s already stated in writing.
Common Impact Windows & Doors Problems We See in Key West Homes
- Jalousie windows that insurance won’t cover. Key West has thousands of 1950s and 1960s jalousie windows still in service, and most carriers now refuse to cover homes where they remain. We replace them with impact units that meet current wind code and give your insurer a documented upgrade.
- Salt-spray corrosion on window hardware. Standard inland hardware seizes and pits within two years on a Key West home. We spec marine-grade stainless or coated hardware on every exterior-facing unit, which is why our hardware doesn’t fuse shut after the first hurricane season.
- HARC rejections on modern aluminum units. Out-of-town crews install a standard aluminum impact window on a contributing structure and HARC issues a stop-work order. The unit comes out, the job sits for weeks, and the homeowner pays twice. We pull the HARC permit first and submit the exact profile for review before ordering.
- Hidden rot in Dade County pine framing. Wind-driven rain gets behind improperly flashed windows in Key West and rots the original Dade County pine framing from the inside. When we pull an old unit, we check the sill pan and flashing tape and upgrade both to marine-grade materials before the new window goes in.
Pricing for Impact Windows & Doors in Key West, FL
A single impact window replacement on a Key West home typically runs $950 to $2,400 installed, depending on size, profile, and whether the opening requires HARC review. Impact sliding glass doors run $3,800 to $8,500, and impact French doors with wood-clad profiles start around $4,200 and top out near $11,000 on contributing historic structures where every lite and mullion needs commission sign-off. A full-house replacement on a standard Conch cottage usually lands between $22,000 and $48,000 depending on the count of openings and the wind-load documentation your insurer requires.
What separates a cheap quote from a compliant one in Key West is the paperwork and the hardware. A low bid often skips the HARC permit, specs inland hardware, and doesn’t register the warranty layers in writing. We give you a line-item quote that shows the HARC filing, the marine-grade hardware, and both warranty layers as separate items. That’s why our numbers look higher up front and cost less by the time the job is done. Call (813) 320-9346 for a free estimate on your Key West home.

FAQs - Impact Windows & Doors in Key West
No. A HARC certificate of appropriateness addresses the visual and historic character of the window; it does not waive any structural or wind-load requirement. Your impact windows must satisfy both the HARC review and Monroe County’s building code, which means the glazing, frame, and anchoring all need to meet the 180+ mph design-load standard even when the exterior profile replicates the original Conch-style wood window. We handle both approvals on the same submission, and we don’t order the units until HARC signs off on the profile. Call (813) 320-9346 and we’ll walk you through what your specific opening requires.
The cost difference comes down to three Key West-specific factors: the HARC permit filing and review period, which adds weeks to the timeline; the wood-clad profile required to match the original divided lites and mullion widths, which costs more than a standard aluminum unit; and the marine-grade hardware needed to survive salt spray, which is a requirement here, not an option. In Miami, you’re buying a window. In Key West, you’re buying a window that has to pass a preservation board and survive a saltwater environment. We show every one of those line items on your quote so you can see exactly where the money goes.
No. A jalousie replacement on a contributing structure in Old Town still requires HARC review because the commission reviews the complete opening, not just the operating style. The approval hinges on the mullion width, lite configuration, and finish, and a true impact-rated louvered window essentially doesn’t exist. What we typically do is spec a double-hung or fixed impact unit that replicates the visual proportion of the original jalousie opening, and we submit the exact profile to HARC before ordering. Call (813) 320-9346 for a quote that includes the HARC filing as a line item.
Your insurer needs three documents: the product approval (NOA or FL number) for each window and door installed, the permit that shows the installation was inspected and passed by Monroe County, and a wind mitigation inspection report (Form 1802) completed by a licensed inspector after the install. We provide the product approvals and the permit documentation as part of every Key West job, and we register both manufacturer warranty layers in writing before we leave. That’s the Keystone Standard. It means when your insurer asks for documentation, you aren’t chasing paperwork weeks after the job is done.
The most common reason is submitting a standard aluminum impact window with a modern profile that doesn’t replicate the original divided lites and mullion widths. HARC rejects it because it “reads wrong” from the street. We avoid it by pulling the HARC permit first, submitting the exact profile with wood-clad exterior and period-appropriate mullion configuration for review before we order, and staying on the phone with the commission staff until we have the sign-off in writing. On a recent jalousie replacement in Truman Annex, we swapped the standard aluminum frame for a wood-clad ViewLux double-hung with marine-grade stainless hardware after the first HARC review flagged the mullion width; the commission approved the revised profile, and the job passed final inspection on the first visit. That added three weeks to the timeline, but it saved the homeowner a stop-work order and a second set of units.
