Fast, Reliable Impact Windows & Doors Across Clewiston
Impact windows and doors in Clewiston have to do two jobs at once: hold up to Hendry County’s Wind-Borne Debris Region requirements and stand up to conditions most of South Florida never deals with. We’re talking about fine carbonized ash from sugarcane burns settling into every track, seal, and weep hole, plus year-round Lake Okeechobee humidity that eats aluminum and swells wood. At TruePane Windows & Doors, our Impact Windows & Doors team knows exactly what that combination does to a house, because we’ve been fixing it in this town long enough to see the same failure patterns repeat every harvest season. We install, replace, and service impact-rated windows and doors in Clewiston the way the work should have been done the first time. If you’re pricing a job, call us at (813) 320-9346 and we’ll give you straight numbers on paper, not a guess over the phone.
Why TruePane Windows & Doors Is Clewiston’s Preferred Impact Windows & Doors Company
Dale Kessler founded TruePane in 2008 on a rule he still keeps on the whiteboard in the shop: if the pane is not true, the job is not done. That rule means something specific in Clewiston, where a window that’s set even slightly out of plane will bind in the heat, leak during a cane-field storm, and collect ash in ways a homeowner won’t notice until the seal is already gone. We build every install around that standard. Years of community service, through a heritage of craft that started with Dale as a second-generation glazier, has taught us that Clewiston homeowners don’t want a fast quote and a faster exit. They want the work done right, the warranty registered with the manufacturer in writing, and a company that still answers the phone a decade later. We’re that company.
Our crew in Clewiston understands the local housing stock, which is a lot of mid-century ranch homes and worker cottages built for US Sugar employees. Those houses have original jalousie or single-pane aluminum frames that are 50 to 70 years old now. They were never designed for wind-borne debris protection, and many have deformed frames from decades of heat cycling and cane dust. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves the driveway. That’s The Keystone Standard, and it’s on every job we do.
The 90-Day Done Right Promise backs all of it. If something isn’t right, we make it right. No paperwork fights, no arguing. We stand behind it, in writing.
Our Impact Windows & Doors Services in Clewiston
Hurricane Impact Windows
Clewiston sits in a Wind-Borne Debris Region under the Florida Building Code, which means any new window you put in has to be impact-rated or protected by an approved shutter system. A typical Hurricane Impact Window replacement in Clewiston runs $900 to $1,600 per opening for a standard double-hung with laminated impact glass and a reinforced frame. We walk you through the difference between PGT, CGI, and Simonton lines so you see exactly what you’re buying, not just a brand name on a quote. We pull the permit, install to the manufacturer’s documented specifications, and make sure the job passes inspection before we call it finished.

Impact Sliding Glass Doors
Sliding glass doors on Clewiston homes work hard. They face the flat, open agricultural landscape east of town, where straight-line winds from tropical systems come through with almost no trees or buildings to slow them down. Impact sliding glass doors in Clewiston typically run $2,800 to $5,500 installed, depending on width, glass package, and whether the existing track needs replacement. We replace rollers, tracks, and weatherstripping at the same time, because a new impact-rated panel on an old corroded track is a leak waiting for the first storm. Lake Okeechobee humidity pits aluminum thresholds faster here than in coastal cities farther east.

Impact Entry & French Doors
Front entry doors and French doors in Clewiston face a specific problem: wood jambs swell with lake moisture, then dry and crack in the cane-field heat, which opens air and water gaps even on newly installed units. An impact-rated entry door system in Clewiston typically runs $2,200 to $4,800, and an impact French door set runs $3,500 to $7,000. We inspect the jamb and threshold on every job. If the rough opening has moved, we fix it before the new door goes in. That’s the difference between a door that seals on day one and a door that binds in July.

Impact Garage Doors
Garage doors take the biggest wind load on many Clewiston homes, especially the older ranch houses where the garage faces the street and the prevailing storm wind. A hurricane-rated garage door in Clewiston starts around $1,800 and can reach $4,500 or more for wider two-car openings. We check the existing tracks and springs, confirm the door meets the current wind-load rating for Hendry County, and install a system that actually does what the sticker says. We don’t leave a door on an old track and call it compliant.

Trusted Brands We Service in Clewiston
We’re an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, Jeld-Wen, PGT, CGI, and ES Windows. For Clewiston work specifically, we often quote PGT, CGI, and Simonton because those lines carry the Miami-Dade and Florida product approvals that Hendry County inspectors recognize without argument. We keep common parts and hardware on the truck for those brands, so a hardware replacement doesn’t turn into a two-week wait. Every quote shows the line, the glass package, the frame material, and both warranty layers in writing. You’ll see exactly what you’re paying for.
Common Impact Windows & Doors Problems We See in Clewiston Homes
- Sugarcane ash clogging weep holes. After harvest season, black ash residue plugs the tiny weep holes in aluminum frames across town. Water can’t drain, it sits in the track, and the silicone seals fail years early. We clean and clear weep holes on every service call and install screens where the openings allow it.
- Deformed jalousie and single-pane aluminum frames. Homes built for US Sugar workers between the 1950s and 1970s often still have original jalousie windows. The frames twist and bow from 50 to 70 years of heat cycling and cane-dust infiltration. Full buck replacement is usually the only honest fix, not an insert retrofit.
- Lake humidity pitting thresholds and swelling jambs. Morning lake fog and near-constant high moisture corrode aluminum thresholds and swell wood door jambs. That opens air and water gaps around even new doors. We replace thresholds and rehang jambs as part of a compliant install.
- Impact systems missing permit paperwork. We’ve seen homes where impact windows were installed by someone who never pulled a permit or registered the warranty. The homeowner thinks they’re protected and they’re not. We pull permits, schedule inspections, and register every warranty layer so you have the documentation for an insurance audit.

FAQs - Impact Windows & Doors in Clewiston
Clewiston is in a Wind-Borne Debris Region under the Florida Building Code, which means impact windows must be tested to withstand a 9-pound 2×4 fired at 34 miles per hour, or meet the equivalent Miami-Dade or Florida product approval standard. We quote products with the approvals Hendry County inspectors recognize, so you don’t fight the permit office. Call (813) 320-9346 and we’ll pull the current code requirement for your specific home and show you which products meet it.
Yes. Hendry County requires a permit for window replacement, and the work has to pass a county inspection. We pull the permit, schedule the inspection, and stay on the job until it passes. You don’t manage the paperwork and you don’t chase the inspector. That’s part of the deal, written into every TruePane quote.
It can and it does. The fine carbonized ash from seasonal cane burns settles into frame tracks, then works its way into the silicone seals and weatherstripping. Once the ash packs into a weep hole, water can’t drain and the frame holds moisture against the seal until it fails. We see this failure mode in Clewiston constantly and almost never in other South Florida towns. That’s why we clean weep holes and check seals on every service call here.
If you have impact windows installed with a permit and a passing inspection, your insurance company sees documented compliance, which can support wind mitigation credits and strengthen a claim after a storm. If the work was done without a permit or the warranty was never registered, the insurer may treat the windows as non-compliant, which can reduce a payout. We register both warranty layers and leave you with the paperwork. That documentation is part of what you’re paying for. Call (813) 320-9346 for an exact quote and we’ll explain what paperwork you’ll have when the job is done.
Many Clewiston homes built for US Sugar workers in the mid-20th century still have original jalousie or single-pane aluminum frames. Those frames are often deformed from decades of heat cycling and cane-dust buildup, and an insert window relies on the old frame being square and sound. When it’s not, the insert won’t seal and the wind load protection drops. Full buck replacement removes the old frame down to the rough opening and rebuilds it plumb, square, and sealed. It costs more than an insert, but it’s the only honest fix for a frame that’s already failing. We’ll show you the condition of your frames before we quote, so you can see why the work is needed.
