Window Replacement in Clewiston, FL: What It Costs and Why Ash Matters More Than Salt
Full-frame window replacement in Clewiston runs $700-$1,800 per opening for standard-size units. Insert replacements run $450-$1,100 per window. The price gap between impact-rated and non-impact-rated jobs here is sharper than in most Florida markets because Clewiston sits on the lake, not the coast, which changes which building codes apply and which hardware actually survives.
We’re TruePane Windows & Doors. Dale Kessler founded this company in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. When you call (754) 238-2201, a live person answers. Not a voicemail tree, not a callback form.
Our crews serve Clewiston directly from our South Florida office. The technicians who show up at your door know what cane ash does to a window track. That matters more than you might think.
What Cane Ash Does to Clewiston Windows That No Coastal Installer Expects
Clewiston has a problem no window company from Fort Myers or Naples will mention because they don’t live with it. Every year from October through March, U.S. Sugar and Florida Crystals burn cane fields in a ring around this city. The smoke rolls over Harney Pond, Pioneer, and the Sugarland Drainage District. It leaves a fine black grit on every exterior surface, including your windows.
That grit drifts into weep holes. Weep holes are the small drainage channels at the bottom of a window frame. When they clog, condensation has nowhere to go. It sits inside the frame, saturates the weatherstripping, and attacks the insulated glass seal from the inside. Homeowners in Clewiston replace thermal-pane windows in six or eight years that should have lasted twenty, because the ash cycle means the frame is constantly fighting standing water.
On a 1960s CBS home near the Sugarland Drainage District, we pulled a failed jalousie unit caked with cane ash. The original aluminum frame had corroded at the jamb, and the single-pane sash was bowed. We flushed the track channels, replaced the unit with an impact-rated double-hung with low-E glass and argon fill, and sealed the flashing tape before reinstalling. That job wasn’t just a window swap. It was a correction for forty years of a climate this house was never designed for.
Then there’s the humidity. Clewiston sits on the southern rim of Lake Okeechobee. The air here holds more moisture than in inland cities of comparable size because an 730-square-mile lake is throwing vapor into the sky a few hundred yards from your house. Legacy aluminum frames from the 1960s and 1970s lose their paint in sheets. Exposed aluminum then corrodes at the jamb and the sash. By the time you see white oxide powder at the corners, the structural integrity of the frame is already gone.
Why TruePane Windows & Doors Is the Clewiston Replacement Crew Homeowners Actually Call
Dale Kessler founded TruePane because he was tired of seeing out-of-true installs and voided warranty paperwork. He grew up around glass and frames as a second-generation glazier. TruePane now carries more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, PGT, and CGI. We are an authorized installer for every line we quote. That means the warranty is real, registered in writing, with durations stated before our truck leaves your driveway.
The Keystone Standard backs every job. Both manufacturer warranty layers get registered before we leave. The Done Right Promise means that if something isn’t right, we make it right. No paperwork fights, no arguing.
Clewiston homeowners tend to be people who have lived in the same house for twenty or thirty years. They remember the contractor who left them with a fogged seal and a door that binds in July. Those are the people we work for. Our technicians are background-checked, uniformed, and trained to measure every opening twice before quoting. You get a written quote with manufacturer lines side by side on paper. You see exactly what you’re buying.
We also offer a permanent 5 percent discount for seniors and veterans in Clewiston. a free written repair estimate, and a maintenance check. Those offers are standing offers, not promotions that expire when the truck leaves.
Our Window Replacement Services in Clewiston
Insert Window Replacement
For Clewiston’s older CBS homes, insert replacements are often the right answer. An insert fits inside the existing frame. We remove the old sashes and hardware, prep the opening, and set the new unit into the original structure. This works well in homes where the concrete block opening is sound and square. It costs less than full-frame replacement and usually takes one day for three to five windows. On homes near the lake, we always flush the weep holes and track channels during an insert job, because cane ash will have collected there.
Energy-Efficient Upgrade
A single-pane jalousie window in Clewiston is not doing you any favors in August. Many original windows in the city’s mid-century housing stock are jalousies with thin aluminum frames and no thermal break. Upgrading to a double-hung or casement unit with low-E glass and argon fill cuts your cooling load meaningfully. In a place where afternoon thunderstorms and lake humidity drive the heat index over 100 for months, an energy-efficient window is not a luxury. It’s the difference between a house that holds 75 degrees and one that struggles to stay below 80. We quote energy-efficient lines side by side so you see the performance ratings, not just the price.
Storm Window Replacement
Clewiston sits inland from the Atlantic, but the Herbert Hoover Dike and Lake Okeechobee change the risk calculation during hurricane season. Inland surge risk exists for low-lying and lakeside properties. Impact-rated windows are a genuine structural upgrade on homes near the lake or in the flood shadow of the dike. A storm window replacement in Clewiston typically involves removing existing single-pane or non-impact sashes and setting impact-rated units with laminated glass. We handle the product approval documentation for Hendry County’s wind-borne debris requirements, so your inspection doesn’t stall on a paperwork detail.
Full Frame Replacement
When the original frame is too far gone for an insert, we do a full-frame replacement. That means removing the entire window down to the rough opening, repairing or replacing the framing, flashing the opening properly, and setting a new unit. This is common on 1960s Clewiston homes where aluminum frames have corroded at the jamb or where water intrusion has rotted interior wood. Full-frame replacement also gives you the chance to address water management issues that inserts can’t fix, like old builders-grade flashing or missing sill pans.
Trusted Brands We Service in Clewiston
TruePane is an authorized installer for, PGT, CGI, ES Windows, and ECO Window Systems. We stock gaskets, rollers, balances, and hardware for most major lines, so a service call on an Andersen or Pella window in Clewiston doesn’t become a three-week parts wait. When you call, we tell you which lines are in stock locally and which have longer lead times. That’s a square deal, not a sales pitch.
Common Window Replacement Problems We See in Clewiston Homes
- Cane ash blocking weep holes. The October-through-March burn cycle deposits carbonaceous grit into the drainage channels at the bottom of the frame. Blocked weep holes trap condensation inside, which attacks the insulated glass seal from the inside and cuts the unit’s life by half or more.
- Lakeside humidity corroding aluminum frames. The constant moisture from Lake Okeechobee peels paint from legacy aluminum frames and then eats into the exposed metal at the jamb and sash. By the time the window sticks or a corner shows white oxide, replacement is usually the only practical fix.
- Post-2000 windows with incomplete wind-borne debris documentation. Hendry County code requires product approvals for impact-rated windows. We see newer Clewiston homes where the original installer never filed the paperwork. An inspection fails, and the homeowner has to pay for tear-out and reinstallation of a window that was supposed to be code-compliant.
- Failed insulated glass units in homes never built for double-pane performance. Some Clewiston homeowners installed thermal-pane replacement windows over original CBS openings without addressing the moisture load. The result is fogged seals within five seasons, especially on the west-facing walls that take the afternoon sun and the lake breeze.
Pricing for Window Replacement in Clewiston, FL
Three things move the price in Clewiston specifically. First, ash damage is often worse than the homeowner realizes, and if a frame is too far gone for an insert, you’re in full-frame territory. Second, homes in the flood shadow of the Herbert Hoover Dike may warrant flood-resistant thresholds and bottom seals, which add cost. Third, older CBS construction sometimes has nonstandard rough openings, which means custom sizing instead of stock units.

FAQs - Window Replacement in Clewiston
That black grit is cane ash from the sugar cane pre-harvest burns that run from October through March around Clewiston. U.S. Sugar and Florida Crystals burn fields to remove leaves before harvest, and the fine particulate settles into weep holes and door tracks across the city. It’s not seen in coastal or most metro Florida markets. If your weep holes keep clogging, have a technician flush them and check the drainage path. Call (754) 238-2201 to schedule a service visit.
Most older Clewiston homes are not legally required to retrofit impact-rated windows, but homes near the lake or in low-lying areas protected by the Herbert Hoover Dike face an inland surge risk that makes impact glass a practical safeguard. If you’re replacing windows on a pre-2000 home, you have the choice. If you’re doing a major renovation or addition, Hendry County code may require wind-borne debris compliance. We’ll tell you what the code requires for your specific property and give you a written quote either way. Call (754) 238-2201 for an exact estimate.
Yes. Ash blocks weep holes, which trap condensation inside the frame, which attacks the insulated glass seal from the inside, causing fogging and seal failure within a few seasons. The failure mechanism is specific to Clewiston’s annual burn cycle and the lake-moisture load. Cleaning the exterior glass does nothing for the ash packed inside the track. The fix is cavity clearing and proper drainage restoration, which is part of every TruePane replacement or service call in this area.
A full-frame replacement removes the entire window down to the rough opening, including the old frame, and sets a new unit with new flashing. An insert fits a new window into the existing frame after the sashes and hardware are removed. In a CBS home where the concrete opening is sound, inserts save money and work well. Where the original aluminum frame is corroded from decades of lakeside humidity, full-frame replacement is the right call because the frame itself is the problem. Call (754) 238-2201 and we’ll assess your openings free.
In Clewiston, we recommend a service check every two to three years, and more frequently if you live east of the lake where cane ash accumulates most heavily. A service call involves flushing weep holes, cleaning tracks, checking seals, and lubricating hardware. It costs less than a replacement and extends the life of your insulated glass units. We offer a maintenance check for exactly this purpose. Call (754) 238-2201 to schedule.
