Fast, Reliable Custom Windows & Doors Across Clewiston
Custom windows and doors in Clewiston are not a luxury order. They are a structural decision, because this town sits in one of the nastiest environments in Florida for a window to live in. Between the carbonized cane ash that settles into every track and weep hole after harvest burns, and the lake humidity that never lets aluminum rest, the wrong unit fails early and fails ugly. We know what Clewiston’s houses are built from, what the Hendry County wind-borne debris code requires, and what a quote needs to include so the work passes inspection the first time. That’s what we do. Call (813) 320-9346 for a free estimate, and we’ll put the numbers on paper before any work is scheduled.
Key Takeaways for Clewiston Homeowners
- Any new exterior window or door in Clewiston must meet Florida Building Code wind-borne debris standards for Hendry County. Not every product sold locally does.
- Clewiston’s cane ash and lake humidity create a combined failure mode you will not find in Fort Myers or West Palm Beach. Weep hole design and flashing details matter more here than almost anywhere else in South Florida.
- A typical custom impact-rated window replacement in Clewiston runs $1,150 to $1,900 per opening installed, depending on frame condition and glazing package.
- Replacement work in Clewiston’s mid-century ranch homes frequently requires full buck replacement, not a simple insert. If your contractor only quotes inserts without pulling a sill, ask why.
- Both manufacturer warranty layers should be registered in writing before the crew leaves your driveway. We do that automatically, on every job.
Why TruePane Windows & Doors Is Clewiston’s Preferred Custom Windows & Doors Company
TruePane Windows & Doors has served South Florida since 2008, led by second-generation glazier Dale Kessler. Dale started this company in 2008 because he was tired of watching homeowners get handed voided warranties and out-of-square installs. That founding rule, if the pane is not true the job is not done, is still on the whiteboard. Our crews work the Clewiston area regularly enough to know the difference between a house off Commerce Street and one off the old Sugarland Highway alignment. Both get the same Keystone Standard, but the approach to flashing and weep management differs house to house.
Clewiston homeowners call us because the work gets done right and the warranty gets registered. Both layers, in writing, durations stated, before the truck leaves the driveway. Background-checked, uniformed technicians measure every rough opening twice, quote manufacturer lines side by side on paper, and register the paperwork the same visit. Our Custom Windows & Doors team handles everything from a single custom transom to full-home impact conversions. No surprise line items. No second appointment left hanging.
We also answer the phone. A live person, 24 hours a day, 7 days a week. No voicemail tree, no regional call center. That matters when you are a homeowner in Clewiston calling about a window that just failed after a harvest burn, and you want to talk to someone who knows what a weep hole is.
Our Custom Windows & Doors Services in Clewiston
Custom Shape Windows
Clewiston has a fair number of mid-century homes with eyebrow, round, and trapezoid windows over entry doors and in gable ends. Big home centers do not stock these. They order from a catalog and hope the rough opening matches. We measure the actual opening, spec the glass package to the orientation, and manufacturer order the unit to fit. A south-facing arch window on a home off Evercane Road takes a different low-E coating than a north-facing unit shaded by an oak. That kind of specificity is not an upcharge. It is the job.

Commercial Storefront Glazing
Storefront work in Clewiston, from the hardware storefronts near the intersection of US 27 and State Road 80 to the farm supply buildings on the edge of town, gets hammered by fine cane particulate. Aluminum storefront framing picks up dust in the tracks and drains, and if the original glazing was set with cheap glazing tape rather than structural silicone, the glass loses its edge seal quickly. We replace storefront systems with structural silicone glazing, fusion-welded corners where the frame design allows it, and weep covers sized for Clewiston’s particulate load. The work is done after hours for active storefronts when needed, and the permit documentation is delivered before we leave.

Curtain Wall Systems
For Clewiston’s commercial and institutional buildings, curtain wall replacement is a different discipline than storefront glass. A curtain wall carries its own dead load, wind load, and thermal movement, and Lake Okeechobee humidity means expansion joints have to be detailed for constant moisture. We order systems through authorized manufacturer channels, and we coordinate engineering stamps before the order goes in. Impact-rated curtain wall in Hendry County requires missile-level C testing for large-missile impact in most instances. We pull the permit, pass the inspection, and file the paperwork. The owner gets a building that actually meets the code, not a nameplate that claims it.

Architectural Grilles & SDLs
Simulated divided lites are popular in Clewiston’s older ranch neighborhoods, where homeowners want the look of a divided wood sash without the maintenance swamp wood becomes here. Lake humidity will swell a wood grille and warp it within two seasons. We spec aluminum SDLs between the glass panes, or exterior grilles with a factory finish rated for coastal-inland exposure. For Clewiston specifically, we avoid internal grilles on any unit where the homeowner wants clean weep drainage, because cane ash builds up behind poorly detailed grille work and traps water inside the frame. A small detail, but it is the difference between a window that lasts twelve years and one that fails in four.

Trusted Brands We Service in Clewiston
TruePane is an authorized installer for more than a dozen manufacturer lines, and for Clewiston work we often quote Andersen, ES Windows because their impact-rated product lines hold up to the inland humidity and particulate environment better than some cheaper alternatives. We quote them side by side on paper, with the same installation scope for each, so you can see exactly what you are paying for. No mystery preference. No steering to the highest margin. If ES Windows comes in at a better value for a rear patio slider, that is what we recommend. Parts and warranty support stay coordinated through our office, and a live person answers when you call to check on an order.
Common Custom Windows & Doors Problems We See in Clewiston Homes
- Clogged weep holes from cane ash. After harvest burns, a fine black ash settles across the whole town. On a window with small or poorly placed weep holes, that ash packs into the tracks, water can not drain, and the insulated glass unit’s edge seal fails from standing moisture. We see this on nearly every original aluminum window in Clewiston neighborhoods like the ranch homes off Redish Circle.
- Corroded aluminum frames and thresholds. Lake Okeechobee’s constant humidity pits aluminum faster than salt air does in some coastal locations. Thresholds on sliding glass doors in homes near the lake or off Pogue Avenue get white corrosion crust, which then eats the threshold screws and pulls the interlock apart.
- Swollen wood door jambs. The same humidity that eats aluminum makes wood front and side door jambs swell and bind. If a Clewiston homeowner says their front door sticks every July and swings fine in February, that is a moisture absorption problem in the jamb, not a settling foundation. The fix is a properly sealed and flashed door system, not planing the jamb again.
- Non-impact jalousie and single-pane windows. Many of Clewiston’s older worker cottages and ranch houses still have original jalousie windows. Jalousie glass fails any wind-borne debris test, period. And the aluminum frames have deformed over 50 or 60 years of heat cycles. Replacing them requires full buck replacement in most cases, because the original wood buck is often compromised by cane dust and humidity.
One Clewiston-Specific Problem You Will Not Hear About Anywhere Else
Clewiston’s position amid US Sugar cane fields means every window and door has to be specified for two things at once: the wind-borne debris code Hendry County enforces under the Florida Building Code, and an ash-clogged weep system that no neighboring Lake Okeechobee town deals with the same way. Fine carbonized ash settles into frame tracks and weeps after every burn season. If the unit’s weep design is not sized and flashed for that particulate load, the frame holds water inside, the insulated glass seal goes, and you get fogged glass and a failed warranty claim the manufacturer will deny because the failure looks like poor drainage. Cheap window quotes almost never account for this. A compliant Clewiston quote includes weeps sized for particulate drainage, a butyl-flashed buck, and sealant details that keep ash out of the frame interior. That is not an add-on we pitch. It is baseline for work in Clewiston.
What the Wind-Borne Debris Code Actually Requires in Clewiston
Hendry County sits in a Wind-Borne Debris Region under the Florida Building Code. That means any exterior window or door in a new build, or any replacement opening in an existing home, has to be either impact-rated per the code’s missile impact cycle testing or protected by an approved shutter or panel. A single pane of tempered glass is not compliant, and neither is a cheap double-pane unit with an AAMA rating but no missile impact listing. For Clewiston specifically, the practical standard is a large-missile impact rating. The product must be tested to survive a 2×4 fired at 50 feet per second, then survive cyclic pressure. An impact-rated window is not just thick glass. It is a laminated interlayer, a structural frame, and a tested assembly. If the quote does not list the product approval number and the installation method, it is not a compliant quote.
On a ranch home off Sugarland Highway, our crew replaced 50-year-old jalousie windows with impact-rated casement units. Every single weep hole was packed with black cane ash. We flashed the buck with butyl tape, upgraded to low-E argon-filled sashes with a U-factor of 0.28, and set the new thresholds on sealed masonry to stop the humid lake air from pitting the aluminum. That job would have failed inside three years if we had skipped the flashing details and just inserted new units into the old ash-filled openings. Compliance is in the details, not the sticker on the glass.
Pricing for Custom Windows & Doors in Clewiston, FL
A custom impact-rated window replacement in Clewiston typically runs $1,150 to $1,900 per opening installed. A full buck replacement on an original mid-century home adds $200 to $400 per opening because of the demolition and re-flashing work. A basic custom architectural grille with simulated divided lites, built into an impact-rated unit, starts around $350 per window above the base unit cost. A custom shape window, like an arch or round top for a gable, usually lands between $1,800 and $3,400 installed, depending on the radius and the glazing package. A full-home conversion on a three-bedroom Clewiston ranch with 12 to 15 openings usually falls between $18,000 and $32,000. Those are honest ranges for this market. The exact number depends on what is behind the trim and what the rough openings look like after 50 years. We do not bid work blind. The quote is written, line-itemed, and good for 30 days. Call (813) 320-9346 to schedule a free estimate.
When you compare quotes in Clewiston, ask if the bid includes permit drawings, product approval numbers, both warranty layers registered in writing, and the flashing details. Our quotes do. A cheaper bid that omits those items is not cheaper. It is unfinished.
The 90-Day Done Right Promise and The Keystone Standard
Every TruePane job carries the 90-Day Done Right Promise. If the work is not right, we come back and make it right. No paperwork fight. No fine print that covers neither side. Under The Keystone Standard, both manufacturer warranty layers are registered in writing and durations stated before our truck leaves your driveway. That means the manufacturer’s glass unit warranty and the frame and hardware warranty are both on file in your name. The workmanship is guaranteed by us for 90 days. If something moves, we adjust it. If a seal fails, the warranty process is already documented. Clewiston homeowners have enough to deal with around harvest season. A warranty should not be one of them.

FAQs - Custom Windows & Doors in Clewiston
Yes. If the opening is being replaced and the sash or frame is removed, the replacement window must meet the current Florida Building Code’s wind-borne debris provisions for Hendry County. A sash-only replacement where the original frame stays may sometimes qualify for repair rather than full replacement, but the practical answer is that most Clewiston homes have original jalousie or single-pane aluminum frames that should not be retained anyway. A compliant route is full opening replacement with an impact-rated product, product approval number on the permit, and installation per the manufacturer’s tested method. Call (813) 320-9346 and we will walk through the code path for your specific openings. Estimates are free.
We detail the weeping system for the particulate environment. That means weep holes sized for drainage under high-particulate loading, internal baffles or covers where the frame design allows, and a flashing and sealant detail that keeps ash from working into the frame interior in the first place. It also means the rough opening gets cleaned and the buck gets butyl-taped before the new frame goes in. A clean drainage path is the only real defense against ash re-clogging. We also tell Clewiston homeowners to rinse the lower track and weeps with a low-pressure hose twice a year, once after the spring burn season ends and once before the summer storm cycle. Call (813) 320-9346 if you want us to look at a window that is already holding water.
It can, but the unit has to be specified correctly. A laminated impact glass package generally performs slightly below a similarly configured non-impact double-pane on pure U-factor, but adding a low-E coating and argon fill gets most laminated impact units into the ENERGY STAR zone for this region. The larger issue in Clewiston is not the glass package. It is the old, leaky, ash-filled frame the glass is going into. If the frame is not properly flashed and sealed, the best glass in the world will not hit a 12% savings number. We quote glass packages with the actual U-factor and SHGC on paper, and we tell you up front what the performance will be. Call (813) 320-9346 for a quote with the performance numbers, not just the price.
It is common in Clewiston because of the lake’s constant humidity, and it is worse here than in drier inland towns to the north. Wood absorbs moisture from the air, and a wood jamb at the south shore of Lake Okeechobee gets a steady dose of it. The jamb swells, the door binds, and the homeowner either planes it down, which opens the reveal and makes the problem worse, or forces the latch until the strike plate loosens. The proper fix is a door system built for the moisture load: a properly sealed and flashed rough opening, a jamb and threshold with a thermal break and good drainage, and a door slab that can handle the humidity without moving. We install custom entry doors in Clewiston with exactly those details. Call (813) 320-9346 and we will inspect the opening before recommending a fix.
You need the original warranty registration paperwork, the product approval information, and the installation details showing the unit was set to the manufacturer’s specification. If the warranty was never registered in writing, and the installer’s flashing and drainage details were never documented, the insurance claim gets hard fast. Under our Keystone Standard, every Clewiston job gets both warranty layers registered before we leave, and the install details are documented in the job file. If a seal fails, we pull the paper, deal with the manufacturer, and get the replacement moving. That is the whole point of having the paperwork in your name from day one. Call (813) 320-9346 if you have a window that is already fogged and you want to know what a claim will need.
