AfterCasement Windows in Fort Myers, FL
Casement windows are hinged on one side and swing outward with a crank, giving you a full, unobstructed opening and a weather-tight seal that few other window styles can match. In Fort Myers, where Gulf-driven humidity and seasonal storms put real pressure on every joint and seal in your home, casement windows are one of the more practical upgrades a homeowner can make. At TruePane Windows & Doors, Dale Kessler and our crew have been setting casement windows correctly for over 42 years as part of our Window Installation services – measured twice, shimmed plumb, and sealed to the opening the way the manufacturer intended.
If you’re weighing a casement replacement or a first-time install and want a straight answer on cost and fit, call us at (239) 323-5522. A live person picks up every call, around the clock, every day of the week. There’s no voicemail maze and no callback queue – just a direct conversation with someone who knows Fort Myers windows.
Our casement work falls under our full Window Installation in Fort Myers offering, which covers everything from single-window swaps to whole-house projects. This page is specifically about casements – how we size and set them, what they cost in this market, and what to watch for when you’re comparing bids.
When You Need Casement Windows
Not every window situation calls for a casement, but there are specific conditions where they’re clearly the right call over Horizontal Roller Windows or other styles. Here are the scenarios we see most often in Fort Myers homes:
- Your existing casements no longer seal against wind-driven rain. In neighborhoods like McGregor and the Caloosahatchee riverfront, older single-pane casements with worn neoprene gaskets let water wick in along the sill during a southwest squall. If you’re toweling up after every summer storm, the seal is gone and the frame may be compromised behind the interior trim.
- The crank mechanism is stripped or frozen. Older aluminum casements common in Fort Myers homes built in the 1970s and 1980s use an espagnolette-style operator that corrodes in salt air. When the handle spins without moving the sash, the operator has failed – and forcing it can crack the frame or break the hinge.
- You’re upgrading for Florida wind-load compliance. Post-Ian permitting reviews pushed a number of homeowners in Cape Coral and South Fort Myers into retrofitting windows that meet current Miami-Dade or ASCE 7 wind-speed requirements. Modern casements from PGT or CGI are available in impact-rated configurations that satisfy Lee County code without the cost of a full structural modification.
- Fogged or failed glass units inside the frame. When the argon or krypton fill between the panes escapes, the insulating value drops and condensation builds between the lites. In Fort Myers summers, that failed seal also allows humidity to climb inside the glass cavity, accelerating interior mold risk near the sill.
- Your home’s natural ventilation is inadequate. Unlike a double-hung that opens roughly 50% of the sash area, a casement window opens 100% of the frame – a meaningful difference in a Fort Myers home that relies on prevailing Southwest breezes to offset cooling costs. Homeowners in Lehigh Acres and Iona who are reducing HVAC run-time often add casements on the southeast-facing walls where wind capture is most consistent.
- You’re remodeling a kitchen or bathroom where clearance matters. Casements can be operated by the crank from across a counter or over a bathtub – unlike a double-hung that requires you to reach across to push the sash up. That’s a practical consideration in a galley kitchen remodel that we handle regularly in older Fort Myers homes.
Our Casement Windows Process
Every casement installation TruePane completes follows a set sequence. The steps below are not a marketing outline – they’re the actual workflow our technicians follow on every job, because shortcuts at any one of them show up as problems later.
- Pre-visit measurement and opening assessment. Before we order anything, a uniformed TruePane technician comes to the home and measures the rough opening at three heights and three widths – not just the corner-to-corner diagonal. Fort Myers homes built before 1990 frequently have out-of-square openings from foundation settling in the sandy substrate common to Lee County. We document those deviations and factor them into the frame order so the unit fits the actual opening, not the nominal one.
- Manufacturer selection and side-by-side quote. We present options from the lines we carry – which include PGT and CGI for impact-rated casements and other manufacturer lines for standard applications – with the specs, warranty durations, and pricing written side by side on paper. You see exactly what each unit offers and what each one costs. No bundled pricing that obscures the per-window figure.
- Permit coordination (when required). Lee County requires a permit for window replacements that change the size of the opening or that involve structural modification of the rough frame. TruePane handles that filing. For like-for-like replacements within the same rough opening, permit requirements are narrower, but we confirm the current Lee County Building Department rules before any work begins – rules that have shifted since Hurricane Ian’s aftermath and continue to be updated.
- Frame removal and opening preparation. The old frame comes out carefully. We inspect the rough sill, jack studs, and header for rot or moisture damage – a step that matters especially in Fort Myers homes where an old leaking casement has been seeping for years. If we find rot, we tell you before we proceed and discuss the repair scope. We do not bury a problem under a new frame.
- Installation to manufacturer specification. The new casement is set plumb and square, fastened at the manufacturer-specified intervals, flashed at the sill and head with the correct membrane type for Florida’s high-humidity exposure category, and sealed with a paintable exterior caulk rated for UV and salt-air exposure. The founding rule here applies directly: if the pane is not true, the job is not done.
- Warranty registration and walkthrough before the truck leaves. Under The Keystone Standard, both manufacturer warranty layers – the glass unit warranty and the frame/hardware warranty – are registered in writing with durations stated before we pull out of the driveway. You also get our 90-Day Done Right Promise: if anything about the installation is not right within 90 days, we make it right. No paperwork fights. No arguing about what the warranty covers. That’s the commitment in writing.
Casement Windows Pricing in Fort Myers
Casement window pricing in Fort Myers ranges from roughly $420 to $1,100 per window installed, depending on the factors listed below. That range reflects current market pricing for residential casement replacements in Lee County as of 2025 – it is not a teaser low and not a worst-case high. Most single-window replacements in a standard Fort Myers home fall between $550 and $800 fully installed.
| Configuration | Typical Installed Range (Fort Myers) |
|---|---|
| Standard aluminum casement, single-pane replacement (like-for-like) | $420 – $580 |
| Vinyl or aluminum casement, double-pane low-E, standard sizes | $550 – $780 |
| Impact-rated casement (PGT, CGI), standard residential sizes | $750 – $1,100 |
| Casement with rot repair or rough-opening modification | Add $120 – $350 depending on scope |
| Permit fee (Lee County, when required) | $80 – $160 typical residential |
What drives cost up or down:
- Glass specification: standard double-pane low-E versus laminated impact glass carries a meaningful price difference – impact glass is thicker, heavier, and requires a reinforced frame and hardware rated for the additional load.
- Frame material: vinyl frames generally cost less than aluminum and offer better thermal performance in Fort Myers’s heat, but aluminum remains the more common material in coastal applications because of its dimensional stability in high humidity.
- Opening condition: a clean, square opening in good structural shape keeps labor time predictable. Rot, settled framing, or a previous installer’s shoddy flashing adds scope.
- Interior and exterior trim: if existing trim is painted to the old frame or is wood that has swollen against it, removal and refit takes additional time.
- Project volume: replacing multiple casements in a single visit reduces the per-window labor cost, since mobilization, setup, and cleanup are shared across the project.
Seniors and veterans receive a standing 5% discount on all TruePane work. Any repair over $250 qualifies for $50 off. Both discounts apply at time of invoice – no coupon code required, no expiration date.

Why Fort Myers Homeowners Choose TruePane for Casement Windows
Dale Kessler started TruePane in 2008 on a specific observation: out-of-true installs and voided warranties were problems that kept recurring because too many window companies treated installation as a transaction rather than a craft. That observation is still accurate, and the company TruePane became is still the answer to it.
The team TruePane fields in Fort Myers is local – technicians who grew up here, whose families live here, and who understand that a window installed wrong in a Florida climate will make itself known every July for the next twenty years. We hire locally and train apprentices into journeymen the way a second-generation glazier’s shop should. Our technicians are background-checked and uniformed, they measure every opening twice, and they quote manufacturer lines side by side so the homeowner sees exactly what they’re buying before a single screw is turned.
We are authorized installers for more than a dozen manufacturer lines, including PGT and CGI for impact-rated casements – which matters in Lee County, where an unauthorized installer can void the manufacturer warranty before the ink on the contract is dry. That authorization is part of what backs The Keystone Standard: both warranty layers registered in writing, durations stated, before the truck leaves.
TruePane has sponsored Lee County events for years because a company that plans to be in town in thirty years acts like it. That’s not a marketing line – it’s the operating principle behind the 90-Day Done Right Promise and every job we put our name on.

FAQs – Casement Windows in Fort Myers
How much do casement windows cost in Fort Myers?
Casement window installation in Fort Myers typically runs $420 to $1,100 per window fully installed, with most standard residential replacements coming in between $550 and $800. Impact-rated casements for hurricane compliance sit at the higher end of that range. The main variables are glass specification (standard double-pane versus laminated impact glass), frame material, opening condition, and whether Lee County requires a permit for your specific job. Call (239) 323-5522 for an exact quote – the estimate is free and there are no surprise line items.
Do casement windows hold up in Fort Myers’s humidity and salt air?
Yes, when they’re specified and installed correctly for the exposure. Aluminum frames with a factory-applied, salt-air-rated finish hold their dimensions well in coastal Fort Myers conditions – better than an uncoated frame that will pit and corrode within a few years. Vinyl is a reasonable alternative inland, where the UV load matters more than salt content. The flashing and sealant at the perimeter are equally important: we use membrane flashing and exterior caulk rated for Florida’s humidity exposure category on every casement we install. A properly set casement with the right glass package will outlast a double-hung or Picture & Fixed Windows in the same opening under Florida conditions, because the full-perimeter compression seal leaves fewer paths for moisture to enter.
Do I need a permit to replace a casement window in Lee County?
It depends on the scope. Like-for-like replacements within the same rough opening in Lee County may qualify for a simplified permit process, but any change to the opening size, frame type, or structural modification requires a full building permit from Lee County Building and Development Services. Post-Ian, permit requirements and inspection protocols for windows have been updated and continue to evolve – TruePane confirms the current requirements before any job begins and handles the permit filing when one is required. You should be cautious of any contractor who tells you a permit is never needed for window work in Fort Myers; that’s not an accurate statement for all situations.
Can you replace just one casement window, or is it better to do them all at once?
We replace single casements regularly – there’s no minimum. That said, replacing multiple windows in a single visit does reduce the per-window cost because mobilization, setup, and cleanup time is shared across the project rather than charged to one unit. If you have several casements that are close to the same age, or if your home’s windows are a matched set from the original construction, doing them together usually makes more economic sense than replacing individual Garden Windows and gives you a consistent frame appearance throughout the house. We’ll give you pricing both ways so you can make the call. Reach us at (239) 323-5522 and we can walk through the math on your specific project.
What is TruePane’s 90-Day Done Right Promise on casement window installations?
The 90-Day Done Right Promise means that if anything about a TruePane casement installation is not right within 90 days of job completion, we come back and make it right – no paperwork, no arguing, no fine print that covers neither party. This applies to the workmanship: the fit, the seal, the crank operation, the trim, and the flashing. It runs alongside, not instead of, the manufacturer warranties, which we register in writing for both layers – glass unit and frame/hardware – before the truck leaves the driveway. The promise is in writing on every contract. If the pane is not true, the job is not done – that’s been the standard at TruePane since Dale Kessler put it on the whiteboard.
