Fast, Reliable Impact Windows & Doors Across Clewiston
Impact windows and doors in Clewiston run roughly $900-$2,800 per opening installed, depending on size, frame material, and whether you’re replacing an original jalousie window or a sliding glass door. Most Clewiston homes we work on are concrete block (CBS) houses from the 1950s through 1980s, so the job usually means retrofitting modern impact-rated units into older rough openings, not a simple swap. We serve Clewiston homes throughout the year, with scheduling built around the fact that harvest season brings its own set of problems to your windows and doors.

Why TruePane Windows & Doors Is Clewiston’s Preferred Impact Windows & Doors Company
We’re not the newest name to show up in Clewiston with a wrapped pickup and a stack of flyers. Dale Kessler founded TruePane in 2008 on a rule that still sits on the whiteboard in our shop: if the pane is not true, the job is not done. That standard travels with every crew we send to Clewiston, and it means we measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway. Homeowners in Clewiston have dealt with plenty of contractors who promise one thing and leave something else behind. We’d rather put it in writing and stand behind it.
Our crews know Clewiston’s housing stock because we work on it regularly. That means we know what a 1960s CBS house near the U.S. Sugar mill district looks like behind the window trim. We know what cane ash does to a sill track after one harvest season. And we know that the answer for a home two blocks from the lake isn’t always the same as the answer for a home out near the industrial park. That local knowledge is the difference between a warranty that holds and a window that fails in three years.
Clewiston customers also get the TruePane standing rules: a live person answers the phone 24 hours a day, seven days a week. Not a voicemail tree. Not a callback form. When you call about your Impact Windows & Doors project, you talk to a person who can actually help. We’re an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, PGT, CGI, and ES Windows, and we stock factory parts for the units we install in Clewiston so a hardware failure doesn’t turn into a six-week wait for a part.
Our Impact Windows & Doors Services in Clewiston
Hurricane Impact Windows
Most Clewiston homes still have original single-pane aluminum jalousie or sliding windows from the middle of the last century. These units were not built for the wind loads this area can see, and they offer almost nothing against the summer heat and humidity that sits over Lake Okeechobee from May through September. We replace them with impact-rated units from manufacturers including ES Windows, and Andersen, sized to the rough opening and anchored per Florida Building Code. On a CBS home, that means proper fastening into the block, not wood shims and hope.
We handle every permit for Clewiston jobs, schedule the inspection, and stay on the project until the inspector signs off. Homeowners who have been through a bad install before tend to ask about that. The answer is simple: we pull the permit, we meet the inspector, we pass.

Impact Sliding Glass Doors
A sliding glass door in Clewiston lives a hard life. Fine cane ash works into the track during harvest season, and the high humidity coming off the lake accelerates corrosion on rollers and track hardware. We replace older sliding doors with impact-rated models built around stainless steel rollers and corrosion-resistant track components, and we set the track pitch so water drains toward the weep holes instead of pooling against the frame. If your existing door binds or you can hear grit in the track when you slide it, that’s a sign the hardware is eating itself.

Impact Entry & French Doors
Entry doors on Clewiston homes fail from the hinge inward. The zinc-plated hinges and handle sets stuffed into many 1980s-era doors rust fast here, and once the hardware binds, the door stops seating square. We specify stainless steel or hot-dip galvanized hardware on every entry and French door we install in Clewiston, even when the manufacturer’s line doesn’t include it by default. That’s a material upgrade most crews never mention because it costs them a few dollars and they’d rather not eat it. We eat it because we know what a corroded hinge set looks like after five years in this humidity.

Impact Garage Doors
Garage doors are the largest opening on most Clewiston homes, and in a wind event they’re the most likely point of sudden failure. We install impact-rated garage doors and reinforcement systems that meet Miami-Dade and Florida Building Code standards, and we inspect the existing tracks and spring assembly before quoting anything. A garage door that isn’t balanced properly will not hold to its rated wind load, no matter what label is on the panel. If your tracks wobble or your springs look like they were installed with whatever was on the truck, we’ll tell you before we sell you a panel.

Trusted Brands We Service in Clewiston
TruePane is an authorized installer for more than a dozen manufacturer lines, and in Clewiston we most often quote ES Windows, ECO Window Systems. We sell across brands because no single manufacturer makes the best window for every opening, and the homeowner should see side-by-side quotes on paper before spending five figures. We also stock local parts for the brands we install in Clewiston, so a failed roller or latch doesn’t strand you for a month waiting on a backorder from out of state. If we install it, we stock parts for it, and we stand behind the work for 90 days under our Done Right Promise.
Common Impact Windows & Doors Problems We See in Clewiston Homes
- Cane ash clogged weep holes. During harvest season, what locals call ‘black snow’ drifts into window tracks and packs into the small drain holes at the bottom of the frame. When those holes clog, water has nowhere to go. It pools, sits against the frame, and rots the wood sub-sill or pits the aluminum from inside. We clear and seal weep channels on every Clewiston job because most Florida crews never do it, and it’s the single biggest preventable failure we see here.
- Rusted door hinges and handle sets from lake humidity. Sitting directly on the southern shore of Lake Okeechobee means air that’s heavy with water vapor nearly year-round. Cheap zinc-plated door hardware doesn’t stand a chance. We see binding entry doors where the hinge pin has rusted solid and the handle set flops loose. We specify stainless or hot-dip galvanized hardware on every replacement.
- Original jalousie windows that leak air, rain, and anything else that wants in. The old single-pane aluminum jalousie windows common on 1950s through 1980s Clewiston homes have no impact rating at all. A wind-borne branch at 60 mph goes straight through the glass. Even without a storm, those open louvers let outside air pour in year-round, which is why the AC runs constantly in summer.
- Standing water in frame corners that never drains. On older homes, the original installers often didn’t pitch the sill or cut proper weep holes at all. Combined with cane ash plugging what drainage exists, you get corners where water sits for weeks after a rain. That leads to pitted aluminum, stained stucco below the window, and eventually rot in the sub-sill.
Pricing for Impact Windows & Doors in Clewiston, FL
A typical impact window replacement in Clewiston runs $900-$1,800 per opening for a standard-size single or double-hung unit installed, including permit and inspection. Impact sliding glass doors run $3,200-$6,500 depending on width and glass package. Impact entry doors run $2,200-$4,500, and impact garage doors run $2,800-$6,000 depending on size and wind rating. If you’re replacing original jalousie windows, expect the higher end of the per-opening range because we’re changing the opening shape, not just swapping a unit.
These are honest numbers for the Clewiston market, not coastal-Palm-Beach numbers and not generic national averages. The spec matters: fusion-welded frames, stainless hardware, proper anchoring into CBS block. The cheap spec costs less up front and then costs you again when the hardware rusts out or the frame sags. We’d rather quote it right the first time and let you decide.

FAQs - Impact Windows & Doors in Clewiston
Cane ash from the Clewiston harvest season works into window tracks, packs into sill weep holes, and traps standing water against the frame. Within a season or two that leads to pitted aluminum frames and rotted wood sub-sills, a failure mode we see in Clewiston and the Glades far more than anywhere else in South Florida. The fix is simple on every job: we clear the weep channels, make sure they drain, and seal the frame corners. Call (954) 280-4413 for an inspection.
Fusion-welded frames are a single continuous piece, which means the corners can’t open up and leak over time the way mechanically fastened corners can. Near Lake Okeechobee, humidity and temperature swings make that corner expansion failure happen faster than inland. We specify fusion-welded frames on Clewiston jobs because we can stand behind them longer, and TruePane’s Done Right Promise means we actually do. Call for a written quote.
Check the weep holes at the bottom of every window frame at least monthly during harvest season, roughly October through April, and clean out any accumulated ash with a stiff brush or small wire. Homes closer to the U.S. Sugar mill district and the surrounding fields will need it more often. If you’ve already got standing water or visible frame pitting, it’s worth a professional look. Call (954) 280-4413 and we’ll send someone out.
We specify stainless steel or hot-dip galvanized hinges and handle sets on every impact entry door in Clewiston. Standard zinc-plated hardware from the big box stores rusts and binds within a few seasons in the lake humidity here. We include the hardware upgrade in every quote and won’t install anything less, because a door that binds is a door that won’t seat square against its frame. Call for a free line-item estimate.
Yes, and the difference is measurable on a Clewiston block home. Replacing original single-pane jalousie windows with impact-rated, low-E insulated units cuts air infiltration almost entirely, and on a CBS house the window and door openings are where most of the uncontrolled air moves. Homeowners in Clewiston routinely report lower AC run times in the summer after replacement, and the windows are far quieter during harvest season too. We’d rather quote you the package and let the utility bill prove it. Call (954) 280-4413 for a free estimate.
