Fast, Reliable Custom Windows & Doors Across Clewiston
Custom windows and doors in Clewiston come down to two things: getting the wind-load rating right under the Florida Building Code, and sealing the opening tight enough to keep cane-burn ash and Lake Okeechobee humidity out of the house. TruePane has served homeowners in the 33440 ZIP code for years, and our Custom Windows & Doors team measures every opening twice, quotes manufacturer lines side by side on paper, and registers both warranty layers before the truck leaves your driveway. Call (888) 635-0804 for a free in-home measure and a written quote you can hold in your hand.
Why TruePane Windows & Doors Is Clewiston’s Preferred Custom Windows & Doors Company
Homeowners in Clewiston call us because we answer the phone. A live person picks up 24 hours a day, seven days a week, not a voicemail tree and not a regional call center. When you call about a window that won’t seal or a door that binds in July humidity, you talk to someone who knows what a jalousie frame looks like after forty years of cane smoke.
TruePane was founded in 2008 by second-generation glazier Dale Kessler, who built the company on one rule he still keeps on the whiteboard: if the pane is not true, the job is not done. We hire local, train apprentices into journeymen, and sponsor county fairs and church roof funds because we plan to be in Clewiston and the surrounding communities in thirty years. The work carries the Done Right Promise: if it is not done right, we make it right, no paperwork and no arguing. Our crews arrive background-checked and uniformed, working in your home the way they would work in their own mother’s.
We coordinate scheduling from our South Florida office and dispatch technicians directly to Clewiston, so you get a local crew that knows the housing stock here, not a subcontractor guessing at the code requirements.
Our Custom Windows & Doors Services in Clewiston
Impact-Rated Glazing with Miami-Dade NOA and Florida Product Approval Documentation
Clewiston sits in a wind-borne debris region under the Florida Building Code, which means every new window or door opening must carry a Florida Product Approval and, for the highest ratings, a Miami-Dade NOA. We install impact-rated units from PGT, CGI, Andersen, and Marvin with design pressures matched to the exact opening. Each quote includes the specific approval numbers for your configuration, so when a wind mitigation inspector shows up, you hand them the paperwork instead of explaining why the big-box installer never gave you any.

Full-Frame Jalousie Replacement with Sealed Low-E Insulated Glass Units
Most of Clewiston’s older homes were built between the 1940s and 1970s to house U.S. Sugar Corporation workers, and many still have original single-pane jalousie windows. Those aluminum louvers were never designed to seal against anything, let alone the fine particulate that settles over the whole town during pre-harvest burns. We pull the entire jalousie frame and replace it with a sealed low-E insulated glass unit in a full-frame install, re-flashing every jamb and threshold as part of the job.

Wind Mitigation Retrofits and Permit-Ready Design Pressure Calculations
Florida Statute 627.0629 requires insurers to offer premium credits for documented wind-mitigation features. A compliant impact window or door opens that door. We prepare permit-ready design pressure calculations for every opening and can connect you with a licensed inspector for the wind-mitigation form. If your current windows lack a Florida Product Approval number, they will not qualify for the credit, no matter how thick the glass looks.

Custom Doors and Sidelight Openings
Clewiston’s original company-era homes frequently have narrow door openings that don’t match today’s standard slab sizes, and newer subdivisions on the outskirts are often built to minimum spec. We fabricate fully custom door units, including impact-rated entry doors, French doors, and sidelight assemblies, sized to the rough opening rather than forcing a standard slab into a hole it doesn’t fit. Therma-Tru and Mr-Glass lines are available for homeowners who want a specific look with a wind-rated core.

Common Custom Windows & Doors Problems We See in Clewiston Homes
- Cane-burn residue in jalousie tracks. Local contractors who open up old jalousie frames during a replacement routinely find the interior tracks caked with a fine grey-black residue from years of cane burns. It’s a telltale sign the home has never had a proper sealed replacement window installed, and it means the air you are breathing inside has been passing through those gaps for decades.
- Corroded aluminum frames from lake-amplified humidity. Living on the southern shore of Lake Okeechobee means evaporation-driven humidity that never really lets up. Aluminum frames pit and oxidize faster here than in drier inland markets, and once the frame corrodes, the glass seal is next.
- Wind-driven rain intrusion from the lake’s open fetch. During tropical events, wind coming across Lake Okeechobee hits Clewiston with very little to slow it down. Failed glazing tape on old double-hung sashes lets that wind-driven rain wick into the subfloor, rotting jambs before the leak is even visible from inside.
- Minimum-code windows that fail a wind mitigation inspection. Cheap builder-grade windows installed to minimum code often lack a Florida Product Approval or HVHZ rating. They pass a basic building inspection but fail the wind mitigation review, and the homeowner loses the premium credit they qualify for under Florida law.
Pricing for Custom Windows & Doors in Clewiston, FL
A typical impact-rated window in Clewiston runs $800 to $1,500 per unit installed. Single-hung impact windows land between $900 and $1,800, while large or custom openings, like a picture window overlooking the lake or a full sliding glass door wall, run $2,500 to $5,000. Whole-home packages for a typical three-bedroom Clewiston house fall between $8,000 and $25,000 or more depending on opening count and frame material. What moves the price here is the wind zone requirement, the floor height, the number of openings, and whether you are doing a full-frame replacement or a retrofit insert. Full-frame jalousie replacement costs more upfront than an insert, but it is the only way to actually seal the opening against cane smoke and lake humidity. We give you a written line-item quote before any work starts, and the price on that quote is the price on the bill. Call (888) 635-0804 to schedule your free in-home measure.
What Custom Windows & Doors Costs in Clewiston
Let’s put the numbers on the table. An impact window in Clewiston averages $800 to $1,500 installed. A standard single-hung impact unit runs $900 to $1,800 depending on size and design pressure rating. Large custom openings, including sliding glass door walls and oversized picture windows, typically run $2,500 to $5,000. A whole-home package for a Clewiston home with twelve to fifteen openings generally lands between $8,000 and $25,000 or more. What changes the number is the opening size, the wind zone requirement, whether the opening is above the first floor, and the frame material, vinyl, aluminum, or thermally broken aluminum. Custom fabrication runs four to six weeks, and once your units arrive, most jobs are installed in as fast as a single day. Call (888) 635-0804 for a free in-home measure and a written quote. No guesswork, no vague talk about “competitive pricing.” You get the number before you sign anything.
Florida Pays You Back
Clewiston homeowners have three state and federal incentives working in their favor, and a good contractor documents for all three. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows and doors qualify. Florida also exempts impact-resistant windows and doors from sales tax, which adds up on a whole-home job. On the federal side, the 25C energy credit returns 30 percent of the product cost, up to $600 per year, on qualifying energy-efficient units. Beyond those, windstorm-premium credits average around 25 percent on the windstorm portion of your policy after a wind-mitigation inspection, which runs $75 to $150. Programs and carriers set the final numbers, so we don’t quote a rebate as a guarantee. We document the work correctly so you can apply for what’s available.
One comparison worth making: impact windows versus hurricane shutters. Shutters only help if someone is home to hang them, and they do nothing for cane-burn smoke, insects, or the daily humidity that rots older frames. Impact-rated windows are permanent protection, always in place, no panels to drag out of the shed in October and April. For a Clewiston homeowner who has lived here through a burn season and a hurricane watch, that distinction writes itself.
Ratings matter on the paperwork. Every unit we quote includes its Miami-Dade NOA or Florida Product Approval number, HVHZ compliance where your wind zone requires it, and design pressures matched to the opening. We never quote a rating above the actual opening requirement, because that’s how you fail an honest inspection and learn about it after the fact.

FAQs - Custom Windows & Doors in Clewiston
Clewiston falls within a wind-borne debris region under the Florida Building Code, which means new and replacement windows and doors must carry a Florida Product Approval for the design pressure required at your specific opening. Some elevated or lakefront exposures require higher design pressures than a standard inland lot. The specific number depends on your home’s location, floor height, and opening size, and our written quote includes the design pressure calculation for every unit. Call (888) 635-0804 and we’ll measure your openings and tell you exactly what your house requires.
Yes. The original jalousie louvers in Clewiston’s older worker cottages and company homes never sealed against anything, and during the pre-harvest burns from October through April that fine grey-black ash works its way through those gaps and settles in the tracks, on the sills, and into the house itself. A sealed impact-rated low-E insulated glass unit in a full-frame install is the only practical barrier against that particulate, full stop. Call (888) 635-0804 for a free measure and we’ll show you what’s in your current window tracks.
It’s a serious problem. Without a Florida Product Approval number and, where applicable, a Miami-Dade NOA, a window is not documented as impact-rated under the Florida Building Code, and it will not qualify for a wind mitigation inspection credit. If a contractor quotes “impact glass” without the approval number, you are buying a story instead of a documented product. We put the approval number in writing for every opening we quote. Call (888) 635-0804 and ask us to explain the approval paperwork, we’ll walk you through it line by line.
Two ways. First, Florida Statute 627.0629 requires your insurer to offer premium credits based on documented wind-mitigation features, and a wind-mitigation inspection form is what makes that credit real. Second, if you file a claim after a wind event and your windows were not documented with the correct approval numbers, the insurer can question whether the damage was caused by a rated event or a pre-existing failure. Documented compliance protects the claim. The wind-mitigation inspection runs $75 to $150 and typically unlocks around 25 percent off the windstorm portion of the premium. Call (888) 635-0804 for a quote that includes the paperwork you need.
Generally, no. A sash replacement inside an original aluminum frame does not change the frame’s design pressure rating, and the completed assembly will not carry a Florida Product Approval. If you want a documented, inspection-ready wind rating, the opening needs a full-frame replacement with the rated unit installed and re-flashed. We can tell you quickly whether your existing frames are worth saving, and in most Clewiston homes with original aluminum, the answer is that they are not. Call (888) 635-0804 and we’ll check.
If you are ready to replace the jalousies that have been letting cane smoke into your living room for decades, or you want a quote on impact-rated windows and doors that will pass a wind mitigation inspection the first time, call (888) 635-0804. A live person answers, and the estimate is free.
