Clewiston is not a coastal market. It’s a company town built around sugar, and the housing stock tells that story in every original jalousie frame and pitted aluminum track we pull. If you live in a worker cottage from the 1950s or a subdivision home on the outskirts, the work is different here than it is in Stuart or Fort Pierce. The Window Installation decisions you make have to answer for cane smoke, lake humidity, and wind-driven rain off Lake Okeechobee all at once.
Why TruePane Windows & Doors Is Clewiston’s Preferred Window Installation Company
We have a live person who answers the phone 24 hours a day, seven days a week. Not a voicemail tree, not a regional call center. When a Clewiston homeowner calls at 7 a.m. because a window won’t seal and the cane burn left ash on the sill overnight, they get a person who knows the area and can schedule a visit. That matters to the 55-to-75 crowd who have lived in these houses for twenty or thirty years and don’t want to explain their neighborhood to a stranger.
Dale Kessler founded TruePane in 2008 as a second-generation glazier who was tired of watching out-of-true installs and voided warranties get passed off as normal. The standard here is The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway. We back the workmanship for 90 days through our Done Right Promise. If the pane is not true, the job is not done.
Our technicians are background-checked and uniformed. They measure every opening twice and quote manufacturer lines side by side on paper so you see exactly what you’re buying. In Clewiston, where so many homes still carry their original openings, that second measurement catches the difference between a square rough opening and one that’s drifted a quarter inch in sixty years of settling.
Our Window Installation Services in Clewiston
Single & Double Hung Windows
Single and double hung windows are the most common upgrade we install in Clewiston, especially in the 1940s-to-1970s worker cottages where original aluminum frames have corroded past the point of repair. A double hung with a properly sealed sash gives you a tight seal against cane ash and humidity, and it operates without fighting a warped jamb. In Clewiston, a typical impact-rated double hung runs $900 to $1,800 per window installed, depending on size and the condition of the surrounding opening.

Casement Windows
Casement windows crank outward and seal against the frame on all four sides, which makes them one of the best choices for wind-driven rain off Lake Okeechobee. We recommend them for lakefront and canal-side homes where the open fetch pushes water hard against window faces during tropical events. A casement with impact glazing and a multi-point lock runs $800 to $1,500 per opening in Clewiston, and the seal stays true because the hinge hardware carries the weight, not the jamb.

3-Panel Sliding (3-Lite Roller) Windows
Three-panel sliders are common in the newer Clewiston subdivisions, particularly where a wide opening faces a patio or a screened porch. The weak point is almost always the roller track and the interlock at the center, which lets fine cane ash work its way in if the rollers have sagged. We set these on new track and verify the interlock seating before the trim goes back. Installed cost for a 3-lite roller in Clewiston lands between $1,200 and $2,500 depending on the rough opening width.

Awning & Hopper Windows
Awning windows hinge at the top and open outward, which lets them shed rain while still venting. They show up in older Clewiston utility rooms and above kitchen counters, usually as original single-pane aluminum that’s now fogged or binding. We replace these with sealed, impact-rated units that use the same footprint, so the interior trim doesn’t need to change. Expect $700 to $1,200 per unit installed in most Clewiston homes.

What Window Installation Costs in Clewiston
The honest range for Clewiston looks like this:
- Impact windows, standard sizes: $800 to $1,500 per window installed
- Impact single or double hung: $900 to $1,800 per window installed
- Large or custom openings (bay, bow, oversized slider): $2,500 to $5,000 per opening

What moves the price in Clewiston is the rough opening count, the wind zone rating required for your specific location, floor height, and the frame material you choose. A 1950s cottage with original jalousies will almost always need sill repair or framing correction once we open the wall, and that work is priced and approved in writing before we touch it. We do not spring change orders on you. Free in-home measure and a written line-item quote are standard on every job. Call (888) 635-0804 to schedule yours.
Common Window Installation Problems We See in Clewiston Homes
Here’s what opening up a Clewiston home actually turns up. This is the spine of why we inspect first and write allowances into the contract.
- Cane ash packed into original jalousie tracks. The controlled burns from October through April send fine grey-black particulate across town. Failed seals let it collect between the glass and jamb. We’ve opened frames with a quarter inch of packed ash behind the track. That residue is a field marker that the home has never had a sealed replacement window.
- Corroded aluminum frames from the lake humidity. Lake Okeechobee evaporation keeps the air wet year round. Aluminum from the 1950s through 1970s pits and oxidizes faster here than in drier inland markets, and warped jambs prevent double hungs from locking or sealing against wind.
- Failed flashing at the rough opening. Many older Clewiston openings received only a bead of caulk against wind-driven rain. Once the window comes out, we find water staining on the subfloor below the sill. That needs correction before a new unit goes in.
- Undersized or rotted framing hidden by trim. Company-era homes were built fast and to minimum spec. When a wall has been holding a jalousie for sixty years, the load path isn’t always square. We repair the framing and pull the permit so the rough opening is corrected to code before the new window is set.
Florida Pays You Back
Clewiston homeowners should know the incentives stack, and we help you understand which ones apply to your project. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact-rated windows. Florida also exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit covers 30% of the product cost up to $600 per year on qualifying units. And after a wind-mitigation inspection, which runs $75 to $150, many carriers apply a windstorm-premium credit that averages around 25% on the windstorm portion. We don’t guarantee any of these numbers. Programs and carriers set final terms. But we do walk you through what a qualifying install looks like on paper so your inspector sees the right documentation.
One thing worth stating plainly: impact windows beat hurricane shutters for Clewiston because they’re permanent. You don’t haul panels out of a shed when a storm tracks toward the lake, and the glass is doing the protection job every day, not just when you have warning. Shutters only work if they’re installed in time and correctly. Impact glass works whether you’re home or not, and it also solves the cane-ash and humidity problem the rest of the year.
What We Found on Sugarland Highway
On a 1950s worker cottage off Sugarland Highway, our crew pulled a corroded original jalousie frame and found the interior track caked with layers of cane-burn ash trapped between the glass and jamb. The sill underneath was water-damaged from years of wind-driven rain working through the failed seal. We wrote a change order for epoxy repair to the sill, then set a PGT impact-rated double hung with a laminated glass interlayer and new sill flashing. The homeowner left with a tight seal and a window that qualified for the Florida Statute 627.0629 wind-mitigation insurance credit. That’s the Clewiston job, and it’s why we inspect before we quote and why every surprise gets priced and approved in writing before we touch the wall.

FAQs - Window Installation in Clewiston
Yes. Window replacement in Clewiston requires a permit through Hendry County, and the permit process triggers a review of the rough opening against current Florida Building Code. On older Sugar Corporation homes, the most common code upgrade is wind-rated anchoring and corrected flashing at the opening. If the framing is undersized or water-damaged, the permit requires correction before the window is set. We pull the permit and manage the inspection for you. Call (888) 635-0804 for a free estimate and we’ll walk you through what your specific home requires.
Cane-burn ash is fine enough to work past a failed seal and accumulate inside the track, where it grinds against rollers and locks and leaves a grey residue on sills and sashes. Over multiple burn seasons, the buildup corrodes aluminum hardware and can seize a sash shut. Homes with properly sealed replacement windows don’t see this because the particulate never gets inside the frame. If you can wipe a grey film off your sill after October, your current windows are failing. Replacement is the fix. Call (888) 635-0804 for an exact quote.
In most cases, yes. After a wind-mitigation inspection, which runs $75 to $150, many carriers apply a windstorm-premium credit that averages around 25% on the windstorm portion for impact-rated openings. The exact credit depends on your carrier and your home’s specific rating, not on us. We cannot guarantee a dollar figure. But we install to meet the Florida Building Code and Miami-Dade NOA or Florida Product Approval standards, which is what the inspection is looking for. Call (888) 635-0804 and we’ll explain what documentation your inspector will want.
Clewiston’s lakefront and canal-front homes need higher design pressure ratings to handle wind-driven rain off Lake Okeechobee’s open fetch. We specify DP ratings based on your specific opening size and wind zone, matched per configuration, never a blanket number above +/-100. The right DP is determined by the Florida Building Code calculation for your exposure, and we confirm it during the measure. Call (888) 635-0804 to schedule a free in-home measure and we’ll give you the exact specification for each opening.
Yes, in most cases. We can set an impact-rated double hung into the original jalousie rough opening and keep the interior trim intact, provided the framing is sound and the opening is square. If the rough opening has drifted or the sill is water-damaged, we repair the framing first and price that work in writing before we start. The trim goes back the way it was unless you want it changed. Call (888) 635-0804 for a free estimate and we’ll tell you exactly what your home’s openings will need.
