AfterFast, Reliable Impact Windows & Doors Across Key West
Impact windows and doors in Key West, FL typically run $1,200 to $4,800 per opening installed, and the critical variable here is not brand preference. It is whether the product carries both HVHZ Miami-Dade NOA certification and, in Old Town and other HARC districts, written approval from the Historic Architectural Review Commission before the permit is pulled. TruePane has been installing to that dual standard in Key West for years because this is a market where a code-compliant window in the wrong muntin profile gets ripped out and redone at the homeowner’s expense. That does not happen on our jobs. Call (754) 238-2201 to talk through what your house actually needs.
Why TruePane Windows & Doors Is Key West’s Preferred Impact Windows & Doors Company
Homeowners in Key West call us because they have watched neighbors get burned. A contractor quotes an impact window, installs it, and then the final inspection fails because the frame color is wrong for HARC or the product lacks the correct wind-load documentation. That is a five-figure mistake in Old Town, and it happens more than anyone in the permit office likes to admit. Our crews know the HARC approval sequence, the HVHZ certification paperwork, and the difference between a window that passes engineering review and one that passes the commission’s visual review. We get both before the first piece of trim comes off.
We are a second-generation glazing company, founded by Dale Kessler on a simple rule that still governs every job: if the pane is not true, the job is not done. Our technicians are background-checked and uniformed, and every quote is written on paper, side by side, so you see exactly what you are buying. Both manufacturer warranty layers are registered in writing before our truck leaves the driveway. That is The Keystone Standard, and it applies to every install we do in Key West.
Dispatch and scheduling for Key West are coordinated from our South Florida office, but the crews that show up know this island. They know what salt air does to standard coastal aluminum in four years. They know which blocks fall under HARC review and which do not. They know that a live person answers our phone 24 hours a day, seven days a week, and that the person on the line can actually speak to what your house needs. Years of community service stands behind the name on the truck.
Our Impact Windows & Doors Services in Key West
If you are in Key West, you do not need a vendor. You need a shop that understands what the building department and the historic board are going to require. Here are the services we handle most in the lower Keys.
Hurricane Impact Windows
Every impact window we install in Key West carries a Miami-Dade NOA number specific to the manufacturer and glass configuration. That means the product has passed missile-impact testing and cyclic wind-pressure testing for High-Velocity Hurricane Zone conditions, the same standard the code requires for everything south of the Monroe County line. We stock CGI, CWS, and ES Windows because those manufacturers have product lines rated for HVHZ and available with the divided-light profiles HARC wants to see in historic districts. A full replacement on a typical Conch house in Old Town usually runs $18,000 to $55,000 depending on opening count and HARC requirements.
Impact Sliding Glass Doors
Key West homes built from the 1880s through the 1930s were not designed for eight-foot glass sliders, but half the homes on Fleming Street and Catherine Street have had them retrofitted over the decades. The salt air here does serious damage to sliding door rollers and tracks, and a door that binds in July is usually a track that has corroded out of true. We install HVHZ-rated impact sliders from CGI and ECO Window Systems with stainless hardware rated for marine exposure. Typical cost in Key West runs $4,500 to $11,000 per door installed, including the old-door removal and flashing work.
Impact Entry & French Doors
Entry doors in Key West take the full brunt of wind-driven salt spray, and a standard steel or aluminum door will show pitting at the threshold within three years. We install impact-rated French and entry doors with frames that carry a marine corrosion rating suitable for a property entirely surrounded by saltwater with no inland buffer. In HARC districts, the door must also match the visual profile of the original opening, including any transom work. Budget $3,200 to $9,500 for a compliant entry door installation in Key West, with French door pairs on the higher end.
Impact Garage Doors
Garage doors in Key West are a weak point in wind mitigation, and insurance companies know it. A non-rated garage door that fails under positive pressure can allow the roof to lift, which turns a $30,000 door replacement into a $300,000 structural claim. We install and reinforce impact-rated garage doors with HVHZ certification and work with the wind mitigation inspector so your finished product gets documented properly. Most garage door replacements run $3,800 to $8,500 depending on width and whether new track hardware is required.

Trusted Brands We Service in Key West
We are an authorized installer for more than a dozen manufacturer lines, and the ones we recommend most in Key West are CGI, ES Windows, and ECO Window Systems. These manufacturers maintain HVHZ certification on their impact products and offer divided-light and architectural profiles that satisfy HARC’s visual requirements. That matters here because replacing a faulty impact window three years after install with a different brand and profile can trigger a compliance problem. We keep service parts for these lines stocked for Key West customers and can typically handle warranty work faster than a contractor who has to order from a distributor in Miami. We register every warranty layer in writing before we leave the job.
Common Impact Windows & Doors Problems We See in Key West Homes
- Jalousie windows that cannot meet code. The louvered jalousie glass common in Conch houses built between 1880 and 1930 predates impact standards by a century and cannot be retrofitted with hurricane-rated glass. Every one of those openings needs a full tear-out and replacement with HARC-reviewed impact units, which is exactly the work we do on Julia Street, William Street, and the blocks around Bahama Village.
- Salt-corroded aluminum frames on coastal-grade windows. Key West has no inland buffer from the Atlantic or the Gulf, so standard “coastal” aluminum, which is rated for intermittent salt exposure, pits and fails within five to seven years here. We specify marine-grade aluminum with fusion-welded corners and stainless hardware, and we replace hardware on existing units that homeowners want to keep in service.
- Wrong muntin profile or frame color in a HARC district. HARC has reversed permitted work after installation because the divided-light profile did not match the original fenestration or the frame color was wrong. A bronze frame in a white Conch house in Old Town is a red flag to the commission. We submit the product spec to HARC before the permit application, which is the only way to guarantee the job passes final inspection without correction.
- Fogged insulated glass in impact units installed poorly. A seal failure on an impact window within a few years of installation usually means the unit was not properly bedded, or the frame was racked during install. Key West’s humidity makes any seal failure visible within months. Our Done Right Promise means if the work is not right, we make it right, with no paperwork fights and no arguing about who caused what.
Our Impact Windows & Doors Services in Key West
Most impact window companies in Florida sell the same product lines and recite the same NOA numbers. What they do not tell you is what the Key West building department and HARC will require before the permit is approved and after the inspection is scheduled. That is where our Impact Windows & Doors team earns the job. We handle the engineering paperwork, the HARC submittal, the permit, the install, and the final wind mitigation documentation. One crew, one contract, one point of responsibility. That is a square deal.
Pricing for Impact Windows & Doors in Key West, FL
Here is what we tell homeowners in Key West when they ask what the work costs, because a square deal starts with a number, not a sales pitch. A single HVHZ impact window, supplied and installed, runs $1,200 to $3,400 depending on size, glass package, and whether HARC review applies. Impact sliding glass doors run $4,500 to $11,000. Impact entry doors run $3,200 to $9,500. Impact garage doors run $3,800 to $8,500. A full-house window replacement on a 1,200 to 1,800 square-foot Conch house in Old Town typically lands between $25,000 and $65,000. The HARC factor is real: if the house is in a historic district, add 8 to 15 percent for pre-approval work, custom divided lites, and the documentation packet. We itemize every line and we do not add change orders after the contract is signed. Call (754) 238-2201 for a free estimate with real numbers.

FAQs - Impact Windows & Doors in Key West
Yes and no. Every impact window anywhere in Monroe County must carry HVHZ Miami-Dade NOA certification, meaning the product has passed missile-impact and cyclic-pressure testing for the High-Velocity Hurricane Zone. HARC approval applies only to properties within designated historic districts in Key West, primarily Old Town, where the commission must sign off on the visual design of the window, including divided-light profile, frame color, and how the window matches the original fenestration. On those properties, both requirements apply and both must be documented before final inspection. If your house is in a HARC district, call (754) 238-2201 before you sign any contract.
Jalousie windows are glass louvers that overlap in a metal frame without a continuous sealed glazing unit, and they cannot be made impact-rated under any manufacturer’s NOA. You cannot fit a jalousie opening with laminated impact glass because the louver clips, the frame profile, and the operating mechanism are all non-compliant. The only code-compliant path in Key West is a full tear-out of the jalousie assembly and replacement with a tested, certified impact window. HARC-reviewed units with true divided lites are available that replicate the louvered look from the street while providing full HVHZ protection. Call us for an exact assessment of your specific openings.
HARC pre-approval is the single biggest driver of timeline and budget on historic-property window work in Key West. If the product is submitted before the permit application, the HARC review typically adds two to four weeks to the schedule. If the product is not submitted and the commission flags the install at final inspection, the homeowner faces a stop-work order, mandatory removal, and a second full install. HARC has reversed permitted work after the fact, usually over frame color or muntin profile. We submit to HARC before we pull the permit, every time, no exceptions. That is the only way to guarantee a one-and-done final inspection.
Most Florida property insurers require a wind mitigation inspection after any impact window or door replacement, and Key West is no exception. The inspector verifies that the installed products carry the proper NOA documentation, that the installation matches the product approval, and that the openings are correctly labeled. We coordinate the inspection and provide the full documentation packet, including NOA sheets and manufacturer warranty registrations, so the inspector has everything needed to sign off. Call (754) 238-2201 and we will walk you through what your specific insurer will ask for.
For a property in Key West, where the island has no inland buffer and every side of the house takes salt spray, window and door frames should be rated for severe marine exposure. That means marine-grade aluminum with a Class 1 anodized finish or an AAMA 2605-rated powder coat over properly treated substrate, plus stainless steel hardware. Standard “coastal-grade” frames, which are typically rated for 1,500-hour salt-spray testing, are not sufficient here. The frames we install on Key West homes are specified for the island’s marine environment and carry documentation that supports a warranty claim if corrosion appears prematurely. We stand behind the work in writing.
