Single & Double Hung Windows in Fort Myers, FL

Single and double hung windows are the most common window type in Fort Myers homes, and replacing or upgrading them is one of the most straightforward ways to cut cooling costs, improve storm protection, and stop fighting with a sash that hasn’t moved freely in a decade. At TruePane Windows & Doors, we’ve been setting these windows plumb, level, and square in Southwest Florida homes since our founding – over 42 years of combined glazier heritage behind every Window Installation. If you want a square deal and a job that holds up through hurricane season, call us at (239) 323-5522 and a live person will pick up, any hour of the day.

This page covers everything specific to single and double hung window work in Fort Myers: when replacement makes sense, how we handle the install, what you’ll pay, and what the warranty actually covers. For a broader look at the full scope of our work, visit our Window Installation in Fort Myers page.

Single vs. Double Hung: What’s the Actual Difference?

A single hung window has one moving sash – the bottom one raises and lowers while the top panel stays fixed. A double hung window lets both sashes move, which matters more than most people realize in Fort Myers. When you can drop the top sash a few inches in the evening and raise the bottom one at the same time, you get a stack effect: hot air drafts out the top while cooler air pulls in from the bottom. In a Fort Myers home without central air running at full blast, that cross-ventilation is worth having for any Window Installation Near Me in Fort Myers, FL.

Double hung windows also tilt inward from both sashes for cleaning – useful when you’ve got two-story windows facing a canal or a screened lanai that makes exterior access awkward. Single hung units cost less upfront and have one less moving part to maintain, which makes them a sensible choice for windows you rarely open, unlike Awning & Hopper Windows or those facing a busy road or set high on a wall.

Neither option is universally right. We measure the opening, talk through how you use the room, and quote both side by side on paper so you can make the call without pressure.

When You Need Single & Double Hung Window Replacement

• The sash sticks, rattles, or won’t lock securely. In Fort Myers, wood frames swell from July through September when humidity sits above 80 percent for weeks. If you’re forcing the sash or the lock no longer aligns, the frame has moved enough that weather-stripping and balance springs can’t compensate.
• You’re seeing fog, condensation, or a milky haze between the glass panes. This is a failed insulated glass seal. In Southwest Florida’s heat, that gap fills with moisture-laden air within days and won’t clear. A re-glaze or full sash replacement is the only fix.
• Your energy bills are climbing and the window feels warm to the touch on the interior. Single-pane aluminum windows, still common in Fort Myers homes built before 1990, conduct heat the way a cast iron skillet does. Low-e impact glass with a proper argon fill changes the equation significantly.
• The window doesn’t meet current Florida Building Code impact requirements. If your home is in a Wind-Borne Debris Region – which covers most of Lee County – non-impact windows may leave you out of compliance and could affect your homeowner’s insurance rate at renewal.
• You’re dealing with salt-air corrosion on the frame or hardware. Homes within a mile or two of the Gulf or the Caloosahatchee see aluminum frames pit and vinyl hardware yellow faster than inland properties. When the frame is corroded to the point that caulk won’t hold, replacement is more cost-effective than repeated repairs.
• The window was installed during a renovation and it’s never been quite right. Off-square rough openings, missing shims, and improperly set flanges are more common than they should be in Fort Myers contractor work from the 2000s building boom. A window that leaks air or water around the frame is almost always an installation problem, not a product defect.

Our Single & Double Hung Window Installation Process

Every install follows the same sequence, without shortcuts, because the steps exist for reasons that show up years later rather than the day of the job.

1. In-home measurement and opening assessment. Dale Kessler and every technician we train measure every rough opening twice – width and height at three points each, diagonal for square, and depth for the sill profile. Fort Myers homes built on slab foundations shift over decades, and a window spec’d from a nominal size rather than an actual field measurement is an install that will fight you on day one.
2. Side-by-side manufacturer quotes on paper. We’re an authorized installer for PGT, CGI, and other manufacturer lines appropriate for Lee County’s wind load requirements. You’ll see the options laid out on paper – frame material, glass package, impact rating, warranty duration – so the comparison is yours to make, not ours to steer.
3. Permit coordination if required. Lee County requires a building permit for window replacements that change the opening size or involve impact-rated glass where none existed before. We handle the paperwork and schedule the inspection so you don’t have to track it.
4. Removal and rough opening preparation. The old window comes out carefully – we protect flooring, furniture, and landscaping. The rough opening gets inspected for rot, water intrusion, or framing damage before anything new goes in. If we find rot in the sill or king studs, we tell you before we proceed, not after.
5. Installation to manufacturer spec and Florida Building Code. Flanges are set, shimmed, and fastened to the specs the manufacturer publishes for Florida’s wind load zones. Flashing tape goes on in the correct order – face, then jamb, then head – because reversed flashing is how water finds its way inside three years after the job. Every sash is tested for smooth operation and lock alignment before we touch the interior trim.
6. Warranty registration before the truck leaves the driveway. This is The Keystone Standard. Both warranty layers – the product warranty and the installation warranty – are registered in writing with durations stated. You get a copy. We keep a copy. The 90-Day Done Right Promise covers our workmanship for 90 days with no paperwork fights. If something isn’t right, we come back and make it right.

Single & Double Hung Window Pricing in Fort Myers

Single and double hung window replacement in Fort Myers typically runs between $450 and $1,200 per window installed, depending on size, glass package, frame material, and whether the rough opening needs any correction. Impact-rated units with low-e glass – the standard most Fort Myers homeowners should be choosing – sit toward the middle and upper end of that range.

Multi-window projects almost always cost less per unit than a single replacement because mobilization and permit costs spread across the job. If you’re replacing four or more windows, ask us about project pricing when you call.

Factors that move the number in Fort Myers specifically: homes in flood zones sometimes require elevated sill heights that affect rough opening prep; properties near the Gulf or Estero Bay face higher wind load requirements that narrow the eligible product list; and older concrete block construction common in McGregor Boulevard and Cape Coral-adjacent neighborhoods sometimes requires specialized fastening that adds labor time.

We offer $50 off any repair over $250, and seniors and veterans receive a permanent 5% discount on every job. Estimates are free, and the price we quote is the price on the invoice – no line items that appear after the work is done.

Why Fort Myers Homeowners Call TruePane

The short version: we’ve been doing this work in Southwest Florida for over 42 years, Dale Kessler built this company because he’d seen too many installs done wrong and too many manufacturers’ warranties voided by improper installation, and we hire people who intend to stay in this trade rather than move on when the next building boom creates a better option.

Every technician we send to your home is background-checked and uniformed. They measure twice. They carry manufacturer documentation for the products they install. They don’t leave until the sashes operate correctly, the locks align, and the warranty is registered. That’s not a marketing claim – it’s the standard Dale set on day one and still holds to, because if the pane is not true, the job is not done.

We sponsor county fairs and local church roof funds not because it moves the needle on a spreadsheet but because we’ve been part of this community for decades and intend to stay. A company that plans to still be answering the phone in thirty years doesn’t cut corners on flashing tape or skip warranty registration to save ten minutes on a job.

We’re an authorized installer for PGT and CGI, both of which manufacture impact-rated windows specifically engineered for Florida’s coastal wind zones. We’re part of our broader home-services network and work alongside other trades in the area when projects call for coordination – but window and door work is all we do, and it’s all we’ve ever done.

FAQs – Single & Double Hung Windows in Fort Myers

How much does it cost to replace a single or double hung window in Fort Myers?

Replacing a single or double hung window in Fort Myers typically costs between $450 and $1,200 installed, depending on size, frame material, and glass package. Impact-rated double hung units with low-e glass – the type most appropriate for Lee County’s wind load requirements – generally run $750 to $1,200 per window. Rough opening repairs, permit fees, and oversized units add to that range. Call (239) 323-5522 for a free in-home estimate; we’ll measure the opening and give you a written quote the same visit.

Do I need a permit to replace windows in Fort Myers?

In Fort Myers and unincorporated Lee County, a building permit is required when window replacement changes the opening size or involves upgrading to impact-rated glazing where none existed before. Like-for-like replacements in the same rough opening size may qualify for a simpler permit path depending on the product being installed. TruePane handles permit coordination on every job that requires one – we submit the application, schedule the inspection, and make sure the work is signed off before we consider the job complete. You won’t need to track it yourself.

What’s the difference between single hung and double hung windows for a Fort Myers home?

A single hung window has a fixed top sash and a movable bottom sash; a double hung window lets both sashes move. In Fort Myers, where ventilation strategy matters during the months when running the air conditioner constantly isn’t practical, double hung windows give you better airflow control – you can drop the top sash to let heat escape while raising the bottom for fresh air. Double hung windows also tilt inward from both sashes for interior cleaning, which is useful on second-floor or lanai-adjacent windows, while 3-Panel Sliding (3-Lite Roller) Windows offer a different opening style entirely. Single hung units cost slightly less and have fewer moving parts, making them a reasonable choice for windows you rarely open.

How long does a single or double hung window installation take?

Most single and double hung window replacements in Fort Myers are completed in one visit. A single window typically takes two to three hours from removal through warranty registration. Whole-house projects with six to ten windows usually run one full day with a two-person crew. If the rough opening needs framing correction or we find rot in the sill, that adds time – but we’ll tell you what we found before we proceed, not after. The job isn’t done until the sash operates correctly, the locks align, and both warranty layers are registered in writing.
