Why TruePane Windows & Doors Is South Bay’s Preferred Window Replacement Company
We’ve been doing Window Replacement work in South Bay long enough to know what the lake and the cane fields do to a window over thirty or forty years. Dale Kessler founded TruePane in 2008 on a rule that still governs every job: if the pane is not true, the job is not done. That standard means we measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers in writing before the truck leaves your driveway.
Our customers in South Bay call us because the person who answers is a live person, 24 hours a day, seven days a week. No voicemail tree, no callback form. When you call about a window that won’t close or a seal that’s fogged, you talk to someone who knows what sugarcane ash does to a track and can schedule a background-checked, uniformed technician to your home in South Bay. We hire locally, train apprentices into journeymen, and act like a company that plans to be in town in thirty years. That’s how we’ve earned our reputation across Palm Beach County’s western edge, and it’s how we keep it.
Our Window Replacement Services in South Bay
South Bay’s housing stock is mostly single-story CBS homes from the 1950s through the 1980s. That means we see the same three or four window problems on nearly every street, and we’ve built our service around dealing with them the right way the first time. Here’s what that looks like on the jobs we do most in South Bay.
Full Frame Replacement
Full frame replacement is the standard for most South Bay homes because the original single-pane aluminum frames are done, not just dated. Decades of Lake Okeechobee humidity have oxidized the aluminum tracks and rotted wood jambs and sills. We pull the entire old unit, repair or replace the rough opening framing, install the new window with flashing tape at the jambs and sill pan, and square everything before we trim it out. In South Bay, full frame replacement is not an upsell; it’s what the house actually needs.

Insert Window Replacement
For South Bay homes where the original frames are still square and solid, an insert replacement drops into the existing opening without tearing out surrounding stucco or interior trim. It’s a lighter-touch job and costs less upfront. But we only recommend inserts when the frame passes inspection. Around here, the weep holes and track channels often tell us the frame has been holding moisture for years, and packing a new sash into a compromised opening just moves the failure down the road a few years.

Storm Window Replacement
South Bay sits in the western reaches of Palm Beach County where hurricanes that track inland still arrive with meaningful Category 1-range sustained winds. Original jalousie windows and old aluminum sliders were never designed for that kind of wind load, and they’re not impact-rated. We install impact-rated storm windows and full impact replacements built to Florida Building Code, because whether or not your home is in a wind-borne debris zone, a window that fails in a storm is a hole in your house. We quote PGT and CGI impact lines for South Bay specifically, because those are the products that hold up when the cane is flattened by the wind you can see coming across the lake.

Energy-Efficient Upgrade
It’s humid in South Bay in a way that people on the coast don’t fully understand. The lake holds moisture in the air, and that moisture drives up the energy load on your air conditioning. Low-E glass and insulated frames do real work here. We can show you the difference on paper between a double-pane low-E unit and an insulated impact unit, with the numbers for heat gain and U-factor side by side, so you can make a decision based on what the window will actually do in August. The senior and veteran discount also applies to energy upgrades, which matters when you’re replacing a dozen windows at once.

Trusted Brands We Service in South Bay
TruePane is an authorized installer for more than a dozen manufacturer lines, and for South Bay we do a lot of work with PGT, CGI impact and energy-efficient products. That’s not a random list. Those three lines hold up to the humidity, the wind, and the ash cycles better than most, and our technicians know their installation specs cold. We stock common replacement parts for those lines locally, so when a South Bay customer calls about a track that’s binding or a sash that won’t seal, we can often fix it on the first trip without waiting on a parts shipment.
Common Window Replacement Problems We See in South Bay Homes
- Sugarcane ash packed into weep holes and door tracks. Every pre-harvest burn in the fields around South Bay puts fine black particles into the air. We call it black snow. It settles into window weep holes and slider tracks, packs down, and traps the lake humidity against the aluminum. The window binds, or the track corrodes under the compacted ash, or water backs up into the frame when it rains. Homeowners often think the seal has failed. Usually the track is just full of ash, and a full flush and weep hole clearing does the work.
- Fogged seals that started on the lake side of the house. The south and east elevations of South Bay homes face Lake Okeechobee and take the brunt of the persistent humidity. We see fogged panes and seal failure show up there first, while the north and west sides of the same house hold up longer. That’s a sign of moisture load, not a defective window batch, and it tells us the replacement needs a frame with a better drainage design.
- Buckled and rotted wood jambs around original windows. It’s not just the aluminum that suffers. Older South Bay homes built with wood jambs or wood sills have been soaking up lake humidity for forty or fifty years. Pull an old window out and you’ll often find the framing ends are soft. We quote for that possibility before we open anything, so the number doesn’t move on you mid-job.
- Single-pane jalousies that leak air like a screen door. South Bay has a lot of original jalousie windows still in service. They were never sealed units. The glass slats overlap but never close tight, they have no real gasketing, and they offer no impact protection. Replacing them with double-hung impact-rated units is the single biggest improvement we make in South Bay homes, both for safety and for the power bill.
Pricing for Window Replacement in South Bay, FL
South Bay’s market runs a bit lower than Palm Beach or Boca Raton because the housing stock is more consistent in size and style, but the fundamentals are the same. A standard insert replacement for a double-hung window in a CBS home in South Bay typically runs $850 to $1,400 per opening. Full frame replacement with a mid-range vinyl or aluminum unit runs $1,200 to $2,200 per window. Impact-rated units from PGT or CGI add $400 to $800 per opening over a non-impact glass package, and energy-efficient low-E double-pane upgrades usually add $150 to $350 per window over standard clear glass. These are the prices we quote in South Bay, written out so you can compare. Call (813) 320-9346 for an exact quote on your windows. The estimate is free, and the price you’re quoted is the price we stand behind. No change orders, no surprise line items, no arguing after the fact.

FAQs - Window Replacement in South Bay
If your slider or jalousie window binds or won’t close around the edges of the track, and you see dark, fine grit packed into the lower track channels or the weep holes at the bottom of the frame, that’s sugarcane ash. It falls during pre-harvest burns and settles into every horizontal surface, including window tracks. The fix is a full track flush and weep hole clearing, which takes a technician about an hour per window face. If the binding has been going on for years, the track may be scored or corroded too, at which point replacement makes more sense than repeated cleanings. Call (813) 320-9346 and we can tell you over the phone whether it sounds like ash buildup or something structural before we even book the appointment.
If your home was built before 2002, the windows are almost certainly not impact-rated, and South Bay’s inland location does not change the fact that hurricanes tracking across the state still arrive here with Category 1-range winds. The Florida Building Code has required impact-resistant glazing or shutters for new work in most of Palm Beach County for years, and a window that fails in a storm is an opening that lets wind pressure into the house. We recommend impact-rated replacements for any South Bay home where the original single-pane units are still in place. The price difference over non-impact glass is meaningful, but so is the difference between a window that holds and one that blows out. We’ll quote both side by side so you can see the numbers.
That’s the Lake Okeechobee humidity load. The elevations of your home that face the lake catch the persistent moisture coming off the water, and over a period of years that moisture finds the weakest point in the insulated glass unit. If the fogging is only on the lake side, it’s not a bad batch of windows; it’s the environment. The fix is a replacement sash or full unit with a better edge seal and a frame design that actually drains, and we have specific product recommendations for South Bay homes that we write into every estimate. Call (813) 320-9346 and ask us which lines we’re seeing hold up best on the lake side of South Bay homes. We’re glad to share that over the phone.
If the rough opening framing is rotted, the right move is to repair it before the new window goes in. That’s a framing repair, not a window replacement line item, and it should be priced and approved in writing before the work happens. Our process is inspection first. We walk the openings, probe the wood, and look for signs of long-term moisture damage before we quote. If we find rot after the old window comes out, we stop and bring you into the conversation. The repair gets written down, priced, and signed before we touch the framing. No surprises, no ballpark numbers that turn into invoices. That’s the whole reason we build allowances into our contracts on older South Bay homes.
In most cases, no, and we won’t do it anyway. The original South Bay jalousie frames were built for single-pane slats that never sealed tight, and they aren’t rated for impact glass, low-E units, or insulated glazing. The frame geometry doesn’t work with modern glass packages, and the aluminum is usually oxidized to the point where even replacing the slats won’t give you a window that closes tight. There are a few heritage houses in South Bay where a restoration makes sense, and for those we do historic window restoration with appropriate materials. But for the standard 1960s CBS home on Southwest 8th Street, the jalousie frames have served their purpose and the right fix is a full replacement with a properly flashed, impact-rated unit.
