AfterFast, Reliable Impact Windows & Doors Across Key West
Impact window and door replacement in Key West runs on a different clock than the rest of Florida. You have Monroe County code demanding Miami-Dade NOA approval and HARC reviewing every louver spacing and sightline on a Conch cottage. Most jobs take 2 to 5 days once permits clear, and a genuine island crew plans staging around alley access and neighbor notice before the first sash comes out. We are that crew. Call (954) 280-4413 for a free estimate and a straight answer on whether your opening needs a HARC-approved profile.
TruePane has worked Old Town lanes, Bahama Village, The Meadows, and New Town. We understand what salt spray does to hardware on a 2-mile-wide island and what HARC wants on a 1910 wood-frame home before you spend a dollar. Our Impact Windows & Doors team handles the whole job: product selection, HARC paperwork, permit filing, install, and both warranty layers registered in writing before we leave the driveway.
Key Takeaways
- Most full-house impact window replacements in Key West run $900-$1,700 per opening for the window itself; installation adds $250-$450 per opening depending on jamb repair and access.
- HARC in Old Town approves only a narrow set of NOA-listed products that mimic original jalousie or multi-lite appearance. Do not order windows before review.
- Salt spray on Key West eats standard extruded aluminum hardware in 2-3 seasons. Specify marine-grade or heavy anodized frames and stainless hardware.
- We file party-wall notice on shared walls, stage in alleys or single parking spaces, and leave a swept site. Call (954) 280-4413.
Why TruePane Windows & Doors Is Key West’s Preferred Impact Windows & Doors Company
We are not a franchise playbook. Dale Kessler founded TruePane in 2008 as a second-generation glazier, and the rule that named the company still governs every opening: if the pane is not true, the job is not done. In Key West, that standard shows up in small things: shimming a 10-inch non-standard rough opening on a Duval Street cottage so the jamb sits plumb, taping every flashing seam, and quoting manufacturer lines side by side on paper so you see exactly what you are buying.
Dale’s standard applies to every job we run on the island. The Keystone Standard means both manufacturer warranty layers get registered in writing, with durations stated, before the truck leaves. The Done Right Promise means if something is not right, we make it right. No arguing. No fine print. These are the terms we have worked under in South Florida since 2008, and Key West homeowners who intend to stay in their house another twenty years are the ones who read them closely.
We answer the phone with a live person, 24 hours a day, seven days a week. That matters when a storm is two days out and you need to know if your existing openings will hold. It also matters when a HARC reviewer flags a mullion profile at 4:15 on a Friday. You call, a person answers, and we tell you the truth.
Our Impact Windows & Doors Services in Key West
Hurricane Impact Windows
Key West housing stock splits into two worlds: New Town and Mid-Town slab homes built after 1970, and Old Town Conch cottages on elevated piers built between roughly 1880 and 1940. The first group often has standard rough openings that accept manufactured impact units from PGT, CGI, or ES Windows without much wall surgery. The second group does not. Jalousie windows, transom lights, and 10-to-12-inch rough openings mean every Old Town job starts with a tape measure and a frank conversation about which Miami-Dade NOA profiles can carry a HARC-approved louvered or multi-lite sightline. We know that list. Most mainland contractors never learn it.
Impact Sliding Glass Doors
A salt-exposed Key West Sliding & Patio Door on a canal or a White Street Pier neighborhood home fails from the bottom up. Rollers pit, tracks corrode, and the door binds by July. We specify marine-grade stainless hardware and heavy anodized frames for any door that sees salt spray, and we quote the upgrade on paper next to the standard line so you see the cost difference in writing. Most replacement sliders in Key West run $2,800-$6,500 installed depending on size, glass package, and frame finish.
Impact Entry & French Doors
Original Conch houses typically have French doors that are beautiful and completely unprotected. HARC cares about them. A replacement entry or French door in the Old Town Historic District must maintain period proportions, and HARC reviewers regularly reject modern panel profiles. We guide each customer through the HARC certificate process and specify NOA-listed doors that have already cleared aesthetic review for Conch-house applications. A typical impact entry door replacement in Key West runs $3,500-$8,000 installed; a full French door set runs $5,000-$12,000.
Impact Garage Doors
Garage doors on Key West are frequently the largest unprotected opening on a canal-front or New Town home. A wind-rated impact garage door carries a Miami-Dade NOA and often makes the difference between a clean wind mitigation inspection and a failed one. We install impact-rated garage doors with reinforced track and storm-rated hinges, and we handle the wind mitigation paperwork that Monroe County needs for insurance credits. Typical impact garage door replacements here run $2,500-$6,000, less if the existing track is salvageable.

You get side-by-side quotes on paper, every line item visible, before you commit.
Common Impact Windows & Doors Problems We See in Key West Homes
- HARC rejection after product order. A homeowner or an out-of-town contractor orders a standard impact window, HARC flags the louver spacing or sightline, and the job stalls for months. We pull HARC-approved profile options before the order goes in, so review happens once, not three times.
- Salt-spray frame pitting and hardware seizure. Basic extruded aluminum corrodes visibly within a few years on Key West, and standard door hardware can fail in 2-3 seasons. We quote marine-grade or heavy anodized frames up front, with the cost spelled out in writing.
- Non-standard rough openings on Conch houses. Many 19th- and early 20th-century wood-frame homes have 10-to-12-inch opening depths that modern manufactured units do not match. We shim, flash-tape, and custom-mill profiles that fit without carving the house.
- Stop-work orders from missing party-wall notice. Tight Old Town lots share walls and alleys. When the neighbor was not notified, work stops. We file notice before the crew arrives, and we keep staging inside one parking space or a shared alley with written permission.
Pricing for Impact Windows & Doors in Key West, FL
Here are honest numbers for Key West’s market. A standard manufactured impact window replacement runs $900-$1,700 per opening for the unit, with installation adding $250-$450 per opening. Custom or semi-custom profiles for HARC-listed jalousie or multi-lite replacements run higher, typically $1,400-$2,600 per window including framing and flashing work. Impact sliding glass doors run $2,800-$6,500 installed. Impact entry doors run $3,500-$8,000. Impact garage doors run $2,500-$6,000. The variables are real and specific: rough-opening depth, jamb condition, HARC review scope, salt-exposure level, and whether we are staging from a shared alley or a single parking spot. We price the job mean, in writing, before any work starts. Call (954) 280-4413 to schedule a free estimate.
We offer a permanent 5% discount for seniors and veterans, a free written repair estimate, and a maintenance check for existing impact units. These are standing offers, not seasonal gimmicks.
How a tight lot affects your quote
Key West lots are not Fort Lauderdale lots. On a 25-foot-wide Old Town parcel, every window and door has to come through a narrow side gate or a shared alley. That changes the quote in two ways. First, staging: we cannot drop a 40-yard container on the street. We stage in a single parking space or inside the alley with written consent from the adjacent owner. Second, scheduling: we coordinate each day’s material delivery around HARC-mandated work hours and noise ordinances, so the job takes a few more hours than it would on an open lot. We tell you this before we quote, because nobody wants a crew that blocks a neighbor’s front door or works past the legal hour. Our crews on Key West plan access first, install second, and leave the path swept.
We Also Serve Cities Near Key West
Our crews regularly run from Key West up the Overseas Highway to Big Pine Key, Marathon, Key Colony Beach, and Tavernier. If your property sits outside city limits or on a smaller key, call and ask. We will tell you straight whether we can make the schedule work and what the drive time does to the quote. For dependable Impact Windows & Doors across the Lower Keys, our Key West team is the one to call.

FAQs - Impact Windows & Doors in Key West
Yes, but only a narrow set of Miami-Dade NOA-approved impact profiles has already cleared HARC aesthetic review for louvered and multi-lite Conch-house replacements. Most standard manufactured jalousie-style impact units get rejected because the louver spacing or frame profile does not match the original. We carry the specific NOA-listed products that have already passed HARC review, and we can guide your submittal so you do not buy windows HARC will not approve. Call (954) 280-4413 for a straight read on your opening.
Yes. On narrow lots we stage inside a single parking space or in a shared alley only with written consent from the adjacent property owner. We file party-wall notice before work starts and keep the neighbor’s path clear all day. If access is too tight for standard staging, we break the delivery into smaller loads and schedule around the city’s noise and work-hour rules. The access plan is part of the quote, not an afterthought.
Yes. HARC governs aesthetics and issues a certificate of appropriateness for work in the Historic District. Monroe County enforces Miami-Dade NOA compliance for hurricane protection. You need both, and they must agree. A window can pass NOA and still fail HARC sightline review, or pass HARC and fail impact testing if the profile was never approved for hurricane zones. We handle both tracks together so the approval does not get stuck between two offices.
Key West is a 2-mile-wide island surrounded by saltwater, so every frame, seal, and hardware component sits in continuous salt spray. Standard extruded aluminum without heavy anodizing pits visibly within a few years, and standard hardware can seize in 2-3 seasons. We specify heavy anodized frames and Key West Glass Railing Systems hardware for any opening within sightline of salt water, and we show you the upgrade cost on paper next to the standard line so there is no surprise on the bill.
A party-wall notice tells the adjacent property owner that work will happen on a shared wall and during which hours. Once filed, noise and work-hour restrictions still apply, typically limiting construction noise to daytime windows on Key West. We schedule the loudest work, cutting and removal, inside those legal hours and do quiet work like shimming, flashing, and cleanup outside them. The notice protects the job from stop-work orders and keeps the neighbor on good terms. Call (954) 280-4413 and we will walk you through the whole sequence.
