Why TruePane Windows & Doors Is Clewiston’s Preferred Window Installation Company
Clewiston is not like the coastal cities east of us. Homeowners here understand that windows face a different kind of abuse: black sugarcane ash after harvest burns, year-round lake humidity off Okeechobee, and straight-line winds rolling across thousands of flat, open acres with nothing to slow them down. We’ve seen what that combination does to window frames, seals, and weep holes, and we’ve built our installation process around it. Our crews know the ranch homes off Sagamore Avenue, the worker cottages around Francisco Street, and the newer builds near Harlem Academy. When a Clewiston homeowner calls, they get a live person on the phone, 24 hours a day, seven days a week. Not a voicemail tree, not a regional call center.
Dale Kessler founded TruePane Windows & Doors in 2008 on a rule that still hangs on the whiteboard: if the pane is not true, the job is not done. That applies whether we’re setting a single casement window in a 1960s cottage or trimming out a full row of impact-rated double-hungs on a canal-front property. Every job carries the 90-Day Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before we pull out of the driveway. We stand behind it. In writing.
We are an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, and Marvin. We quote those lines side by side on paper so you see exactly what you’re buying. Permanent 5% discount for seniors and veterans. a free written repair estimate. maintenance check. Those are standing offers, not gimmicks.

Our Window Installation Services in Clewiston
Our Window Installation team handles the full range of residential work in Clewiston, from single-sash replacements to whole-house retrofits. Here are the services Clewiston homeowners call us for most often.
Casement Windows
Casement windows seal tighter than any other operating style, which matters when lake-driven wind presses against the frame. In Clewiston’s older ranch homes, we often replace failed jalousie units with casements because the continuous compression seal holds up to both wind and cane dust better than sliding tracks. A standard casement replacement in Clewiston runs $550-$1,200 per opening, more when Impact Windows & Doors - Clewiston glazing is required. The crank hardware we use is stainless, not zinc, because the humidity here eats cheap hardware within two seasons.

Fixed & Picture Windows
Fixed and picture windows are the workhorses of Clewiston’s lakefront and canal-facing homes. There are no moving parts, no tracks for ash to collect in, and no seals to fail from repeated operation. When we install a picture window in Clewiston, we pay close attention to the frame buck. Many of these openings were originally framed for jalousie units, and the aluminum bucks are often deformed. We fix the buck first, then set the window. Picture window installation in Clewiston typically runs $600-$1,800 depending on size and whether impact glazing is specified.

Single & Double Hung Windows
Single and double hung windows are the most common replacement we install in Clewiston’s mid-century housing stock. In homes along Sagamore Avenue and Francisco Street, the original sashes are often 50-70 years old, warped, and painted shut. A double hung replacement with Energy-Efficient Windows - Clewiston low-E/argon glass runs $480-$950 per opening for a standard size. We recommend fusion-welded vinyl frames for these homes. They don’t corrode the way aluminum does in this lake humidity, and they won’t twist like the old frames did after decades of heat cycling and cane-dust infiltration.

Awning Windows
Awning windows work well in Clewiston because they can be left cracked open during rain without letting water in. That’s a real advantage in a town where afternoon thunderstorms roll across the lake without much warning. Installation is similar to casements, and the pricing sits in the same range: $550-$1,200 per opening. We see a lot of awning windows go into Clewiston bathrooms and kitchens where the old jalousie units let in more bugs than air.

Common Window Installation Problems We See in Clewiston Homes
- Deformed aluminum bucks from original jalousie units. The original frames twist after decades of heat and dust. When a new insert window goes into a deformed buck, it binds before the first season. We replace the buck when it won’t hold a square opening, then set the new window properly.
- Ash-clogged weep holes after sugarcane harvest. Black cane ash settles into the drainage channels at the bottom of the frame. When those weep holes plug, water backs up into the sash track and destroys the seals within a year. Post-harvest weep cleaning is standard on every Clewiston install we do.
- Non-impact glass installed in a Wind-Borne Debris Region. The Florida Building Code requires impact-rated glazing in Hendry County. We see windows installed by out-of-town crews that fail to meet the code. That’s a rejection at inspection and a shattered window in the next straight-line storm. We install to code. Permits pulled, inspections passed.
- Pitted aluminum thresholds and swollen wood jambs. Lake Okeechobee humidity causes wood to swell and aluminum to pit. The original thresholds on Clewiston’s 1950s and 1960s cottages are often so deteriorated that a simple window replacement turns into a jamb and threshold repair. We quote that work upfront so there’s no change order later.
On a 1960s worker cottage off Sagamore Avenue, our crew pulled out a row of failed jalousie windows and found the sashes so warped from cane-dust heat cycling that full buck replacement was the only option. We installed fusion-welded vinyl double-hungs with impact-rated glazing and low-E/argon glass, then re-flashed every opening with butyl tape before trimming. After the next harvest burn, we returned to clear ash from the weep holes so the new frames wouldn’t hold water.
That’s not the kind of detail a generic Florida window company thinks about. That’s the difference between a window that lasts two seasons and one that lasts twenty years.

FAQs - Window Installation in Clewiston
Yes, if they want the window to drain properly. Clewiston sits in the middle of US Sugar’s cane fields, and after each harvest burn, fine black ash settles on every horizontal surface. Window weep holes clog with that ash. If the holes aren’t cleared, water backs up into the sash track and degrades the seals within a year. We include post-harvest weep cleaning as standard on every Clewiston installation. Call (813) 320-9346 to schedule a post-harvest inspection or a free estimate for replacement windows.
Not always. If the original jalousie frame is straight and square, a new insert can work. But in Clewiston’s older worker cottages, the aluminum frames are often twisted from decades of heat cycling and cane-dust infiltration. A new insert set into a deformed frame will bind and leak. Full buck replacement is usually the honest answer. We measure every opening twice and tell you which way it has to go before we quote a single window.
Lake Okeechobee creates a micro-humidity environment in Clewiston. Morning lake fog and constant moisture cause wood to swell and aluminum to pit. On new windows, that humidity accelerates seal failure if the weep system isn’t kept clear. Seals last longer when the frame drains. That’s why we inspect and clean weep holes as part of every Clewiston install, and why we recommend impact-rated glazing with low-E/argon that holds up to this moisture environment. Call (813) 320-9346 for a free estimate and a straight answer about what your windows need here.
Because Hendry County is a Wind-Borne Debris Region under the Florida Building Code, and Clewiston’s flat, open agricultural landscape channels straight-line winds from tropical systems with nothing to slow them down. A window that doesn’t meet impact rating fails inspection and shatters when the wind hits. It’s not an upgrade question. It’s the code. We install impact-rated glazing from PGT, CGI, and other manufacturers, and we pull the permit so the inspection is a formality, not a fight.
Yes. The ash is fine enough to sift through the smallest gaps in the sash track. Double-hung windows are particularly vulnerable because the ash works into the balance mechanism and the track channel. We tell every Clewiston customer to expect this, and we schedule a post-harvest track cleaning if they want it. It’s a ten-minute job that adds years to the window’s service life. The maintenance check covers it.
