Why TruePane Windows & Doors Is Clewiston’s Preferred Window Replacement Company
TruePane was founded by second-generation glazier Dale Kessler in 2008, but the craft behind it goes back many years. Dale’s rule is taped to the whiteboard in the office: if the pane is not true, the job is not done.

We carry ourselves like a company that plans to be in town in thirty years, because that’s the plan.

If it’s not done right, we make it right. No paperwork fights, no arguing, no fine print that covers neither. Residents across the 33440 zip code know they can reach us around the clock, because a live person picks up the phone every single time.
Our Window Replacement Services in Clewiston
Full Frame Replacement
The old homes in Clewiston were built for a different era. Original wood sashes and jalousie frames from the 1940s through 1970s sit directly against masonry or wood framing that’s had decades to rot, shift, and soak up lake humidity. Full frame replacement removes everything down to the rough opening so we can inspect the jamb and sill for hidden water damage before a single fastener goes in. This is the job we recommend for most Clewiston worker cottages, because a partial fix on a compromised frame just pushes the real problem down the road.

Insert Window Replacement
If the existing frame is square and solid, an insert can replace the sash and hardware without disturbing trim or siding. It’s a faster job and often costs less, which makes sense for homeowners who need to replace a handful of windows but want to stage the work. We measure every opening twice, quote manufacturer lines side by side on paper, and tell you honestly if an insert will work or if a full frame is the only right answer.

Vinyl Replacement Windows
Vinyl has become the standard for Clewiston homes because it handles humidity without corroding the way aluminum does. The lake evaporation keeps moisture in the air year-round, and we’ve pulled out aluminum frames so pitted and oxidized the sash channels crumbled in our hands. A well-built vinyl replacement window with compression gaskets and a tight seal keeps that moisture outside where it belongs.

Energy-Efficient Upgrade
When you replace a single-pane jalousie with a modern insulated unit, the difference is immediate. Rooms stop sweating in August, the AC doesn’t run as hard, and cane-burn smoke stops leaving that grey-black film on the windowsills. We’ll walk you through the glass packages, Low-E coatings, and gas fills that make sense for Clewiston’s climate, and we’ll show you the manufacturer’s performance numbers on paper before you commit to anything.

Impact-Rated Glazing Upgrade
Clewiston sits in a wind zone that requires Florida Building Code-rated openings on new construction, and existing homes benefit from the same standard. Impact-rated laminated glass protects against wind-driven debris during tropical events, but it also functions as a permanent barrier against cane smoke and ash infiltration during the controlled burns that run roughly October through April. That dual benefit is specific to Clewiston and the Lake Okeechobee sugar corridor, and it makes impact glazing a practical upgrade even if you’re not replacing every window on the house.

Window Maintenance & Care
Windows in Clewiston work harder than windows in most of Florida. Ash from field burns settles on tracks and frames. Humidity accelerates oxidation. Wind-driven rain from the lake finds every weakness in old glazing tape. We offer maintenance service that keeps your windows closing tightly and sealing properly between replacements, and our maintenance check covers cleaning, lubrication, hardware adjustment, and a full seal inspection. For windows that need actual repair, take a free written repair estimate.

Trusted Brands We Service in Clewiston
We’re an authorized installer for more than a dozen manufacturer lines, and for Clewiston homes we regularly specify PGT and CGI for impact-rated applications and ViewLux for energy-conscious vinyl replacements. We don’t steer you toward a single brand. We quote options side by side on paper so you see exactly what you’re buying, from glass package to frame material to hardware. Because we register both warranty layers in writing before we leave the driveway, you get the full manufacturer protection, not whatever a subcontractor remembered to file.
Common Window Replacement Problems We See in Clewiston Homes
- Corroded jalousie tracks and hardware. Years of lake humidity and cane-burn ash leave the aluminum channels pitted and frozen. The windows won’t close tightly, which is a serious problem when a tropical system is spinning off the lake.
- Failed glazing tape on original single-pane windows. Wind-driven rain works its way into the wall cavity, rotting the rough opening from the inside out. We find this on older cottages throughout the 33440 zip code, and it’s the number one reason a supposed insert job turns into a full frame replacement.
- Undersized wood headers over old openings. When original windows get replaced with heavier impact-rated glass, the existing header sometimes can’t carry the load. We check the rough opening before ordering anything, and if the header needs reframing, the permit covers it and you approve the change in writing before we proceed.
- Cane-smoke infiltration through worn seals. Even when windows are closed, fine particulate from the pre-harvest burns slips through deteriorated gaskets and leaves a visible grey-black residue on sills and interior surfaces. This is a telltale sign unique to Clewiston’s burn season, and it almost always means the seals have failed.
Key Takeaways
- Impact-rated windows in Clewiston cost roughly $800 to $1,800 per opening installed, and whole-home packages run $8,000 to $25,000+.
- Clewiston’s lake humidity and cane-burn ash corrode aluminum frames and destroy seals faster than inland markets.
- We inspect the rough opening before quoting so the permit, budget, and scope are set before work starts.
- TruePane is backed by years of glazier tradition, a Done Right Promise, and The Keystone Standard on every job.

What Window Replacement Costs in Clewiston
Here’s the breakdown that matters when you’re planning a window replacement budget in Clewiston:
- Impact windows (standard sizes): $800 to $1,500 per window installed.
- Impact single-hung: $900 to $1,800 per window installed.
- Large or custom openings: $2,500 to $5,000 per window installed.
- Whole-home packages: $8,000 to $25,000+, depending on window count and scope.
What moves the price in Clewiston specifically? Opening count is the biggest factor, followed by wind zone requirements. Homes on the southern lake shore of Okeechobee face stronger wind-driven rain than inland properties, so design pressures and glazing specs matter more here. Floor height raises labor costs if we’re working above a single story. And frame material, whether you choose vinyl, aluminum, or composite, shifts the per-unit price but also affects long-term durability in this humidity. We measure every opening twice and give you a written, itemized quote before any work is ordered. Free in-home measure, no obligation.
Florida Pays You Back
The incentive stack for Clewiston homeowners is real, and we walk you through it honestly. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact-rated windows and doors. Florida also exempts impact-resistant windows and doors from sales tax, which takes a meaningful chunk off the total bill. On the federal side, the 25C energy credit covers 30% of the product cost on qualifying energy-efficient units, up to $600 per year. And after a wind-mitigation inspection, which runs about $75 to $150, many homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of their policy. We don’t guess at these numbers for you, and we don’t make promises about what your carrier or the state will approve. We install to the standard that qualifies, and you take the documentation to the people who write the checks.
One comparison worth understanding: impact windows versus hurricane shutters. Shutters protect the opening during a storm, but they require someone to hang them, store them, and hope they’re in place when the warning comes. Impact windows protect the home permanently, with no panels to deploy and no decision to make at 3 a.m. when a squall is spinning off Lake Okeechobee. They also work every day of the year against cane smoke, humidity, and the normal wear that breaks down older windows. For a Clewiston home, the practical difference is substantial.
What Actually Happens When We Open Up a Clewiston Window
This is the part a generic window replacement page never covers, and it’s the most important thing to understand before you sign a contract. Clewiston’s housing stock runs old. The worker cottages and company-era homes built between the 1940s and 1970s were framed with materials and methods that met the code of their day, not the wind and moisture loads of today. When our crew opens up a 60-year-old jalousie frame, we regularly find three things.
First, the rough opening is often rotted. Clewiston’s location on the southern shore of Lake Okeechobee amplifies wind-driven rain during tropical events, and failed glazing tape around original single-pane windows lets that rain seep into the wall cavity for years before anyone notices. By the time the window comes out, the jamb and sill need replacement. We check for that rot before a single fastener goes in, and we tell you what we find with photos and a written change order if the scope expands.
Second, the headers over old window openings are sometimes undersized for impact-rated glass. A 2×4 header that’s carried a lightweight jalousie for fifty years may sag under the weight of a new Miami-Dade NOA-rated impact unit. If that’s the case, the permit triggers a reframe, and we do it properly under inspection. The cost goes up, but you approve the number in writing before we touch the opening. No surprises, no arguing.
Third, the tracks themselves are often caked with a fine grey-black residue from decades of cane burns. That’s a signature unique to Clewiston and the immediate sugar corridor. It tells us the home has never had a proper sealed replacement window installed, and it tells you exactly why the new windows matter. We found exactly this on a 1950s worker cottage near the U.S. Sugar mill on Sagamore Avenue. The original jalousie frames were so corroded the sash channels crumbled when we pulled them. We did a full-frame replacement with PGT impact-rated casements. The homeowner later told us cane-burn season no longer leaves residue on the windowsills, because the laminated glass interlayer and tight compression gaskets keep the smoke out. That’s what a proper sealed replacement window does in Clewiston.
This inspection-first approach is the single biggest reason a window replacement quote moves. We don’t bid low and then pad the job with change orders. We inspect the opening, identify what’s actually there, and write allowances into the contract for the conditions we expect. If we open the wall and find something worse, you see it before you pay for it. The permit stays clean, the budget stays honest, and the job is done right.

FAQs - Window Replacement in Clewiston
Yes, window replacement in Clewiston requires a permit when the opening is being altered, which includes full frame replacement and any job involving impact-rated glazing. The permit triggers a building inspection, and if the inspector finds undersized headers, rotted framing, or improper flashing from previous work, those conditions must be corrected before the job can close out. We pull permits on every job that requires them, and inspections are passed before we call the work complete. Call (888) 635-0804 and we’ll walk you through exactly what your specific project triggers.
Clewiston’s position on the southern shore of Lake Okeechobee keeps humidity elevated year-round, and lake evaporation accelerates oxidation on aluminum frames far faster than drier inland markets see. Add cane-burn ash settling on the metal during the October-to-April burn season, and you get the pitting and corrosion that freezes jalousie tracks and breaks hardware. The fix is replacing aluminum with vinyl or composite frames and impact-rated glass that seals properly. We quote those options side by side so you can compare. Estimates are free at (888) 635-0804.
Yes. When window seals and gaskets wear out, the fine particulate from controlled sugarcane burns passes through the gaps even with the sashes fully closed. Homeowners see it as a grey-black film on sills and interior surfaces. New replacement windows with compression gaskets and tight laminated glass stop that infiltration entirely, which is a benefit Clewiston homeowners notice within the first burn season after replacement. Call (888) 635-0804 to schedule a free assessment of your current windows.
Many insurers offer windstorm-premium credits after a wind-mitigation inspection verifies impact-rated openings, with credits averaging around 25% on the windstorm portion of the policy. The inspection typically runs $75 to $150, and the final credit amount is set by your carrier, not by us. We install to the standard that qualifies and register both warranty layers in writing so you have the documentation your insurer needs. Call (888) 635-0804 and we’ll explain what your house needs to qualify.
An insert replacement fits a new sash and frame into the existing rough opening without removing the old frame or trim. It works when the original frame is square, solid, and free of rot. A full frame replacement removes everything down to the studs. For Clewiston worker cottages built in the 1940s through 1970s, the original jalousie frames are often so corroded by lake humidity and cane ash that an insert won’t seal properly, and the rough opening itself needs repair. We’ll tell you which job your house actually needs after we open up a sample opening and inspect what’s underneath. Call (888) 635-0804 for a free in-home measure.
