Fast, Reliable Custom Windows & Doors Across South Bay
A custom window or door job in South Bay costs between $1,200 and $4,800 for most single-unit replacements, with whole-home impact-rated packages running $18,000 to $55,000 depending on opening counts and frame materials. We quote the job on paper before any work starts, and we register both warranty layers in writing before the truck leaves your driveway. That’s the way Dale Kessler set it up in 2008, and we haven’t changed it since.
South Bay sits against the southern shore of Lake Okeechobee, and everything about windows and doors here gets tested harder than it does in Belle Glade or Pahokee. Ground moisture sits heavy. Sugarcane ash rides the wind from November through April. When a storm pushes water up against the Herbert Hoover Dike, the air itself feels wet for days. We know what that does to a jalousie frame from 1965, because we’ve pulled enough of them out of block homes off Palm Beach Road and Main Street to have stopped counting. Call (954) 280-4413 and a live person answers, 24 hours a day, seven days a week.
Key Takeaways:
- South Bay’s lake-driven humidity demands flood-rated door pans, marine-grade hardware, and elevated thresholds that inland-spec installations don’t include.
- Sugarcane ash from the November-April burn season fouls aluminum tracks and eats rubber weatherstripping within a single season if not addressed.
- Most South Bay block homes still have original single-pane aluminum or jalousie windows that fail Florida Building Code hurricane-protection requirements.
- TruePane offers the Done Right Promise and The Keystone Standard: both warranty layers registered in writing before we leave.
- Free estimates. A live person answers every call at (954) 280-4413.
Why TruePane Windows & Doors Is South Bay’s Preferred Custom Windows & Doors Company
We’re not a franchise that sends a different crew every month. TruePane Windows & Doors is led by Dale Kessler, a second-generation glazier, and our Custom Windows & Doors team works from a simple rule that’s been on his whiteboard for years: if the pane is not true, the job is not done. That standard applies to every custom shape window, every storefront, every oversized glass panel we set in South Bay.
Homeowners here have told us the same story plenty of times. They hired someone who showed up late, measured once, and left a fogged seal six months later. Then the warranty paperwork never got filed, and the phone number stopped working. We register both manufacturer warranty layers in writing on every single job. Durations are stated. There’s no arguing, no fine print that covers neither party. The Done Right Promise means if it’s not done right, we make it right. That’s not a slogan. It’s in writing.
Our technicians are background-checked and uniformed. They measure every opening twice. They quote manufacturer lines side by side on paper so you can see exactly what you’re buying, from PGT and CGI to Ply Gem and CWS. We hire local, we train apprentices into journeymen, and we plan on being in South Bay for the next thirty years. The company sponsors county fairs and church roof funds because we intend to be around long enough for that to matter.
Our Custom Windows & Doors Services in South Bay
Most of the work we do in South Bay starts the same way: a homeowner is tired of fighting a slider that binds every spring, or worried about a window that hasn’t been hurricane-rated since the Nixon administration. Here’s what we handle most often.
Custom Shape Windows
South Bay block homes aren’t full of round-tops and arches the way some newer developments are, but when a homeowner wants a custom radius window over a kitchen sink or a trapezoid unit in a gable end, we template every opening by hand and order the glass to match. Those openings have to be flashed correctly against Lake Okeechobee’s humidity. A standard square window flashing detail won’t cut it on a shape window here, not when storm-driven lateral moisture gets behind the flange. We use stainless steel flashing tape and marine-grade sealant on every custom shape we set in South Bay.

Commercial Storefront Glazing
Small commercial buildings along Main Street and State Road 80 deal with the same ground moisture as the houses, plus foot traffic and the occasional mower kick from the grass strip. We replace cracked storefront glass, rebuild aluminum frames that have corroded at the sill line, and set new tempered units to code. Most commercial jobs in South Bay run $1,400 to $6,000 depending on opening size and glass type. We’ll measure twice and give you a written line-item quote before any glass gets ordered.

Curtain Wall Systems
Larger commercial and municipal buildings in the South Bay area sometimes need full curtain wall replacement or repair, and the lake environment makes corrosion resistance the first conversation we have. We specify anodized or painted aluminum framing with stainless steel fasteners, thermally broken where energy performance matters. A curtain wall failure near Lake Okeechobee is rarely about the glass breaking. It’s about the millionscrew at the mullion slowly letting go after a decade of ambient moisture. We fix it so it stays fixed.

Architectural Grilles & SDLs
South Bay’s historic block homes have a certain look, and not everyone wants to erase it. Simulated divided lites and architectural grilles let a replacement window keep the character of a 1960s Florida house while upgrading to impact-rated, low-E insulated glass. We install interior and exterior SDL grids, true divided lites on select lines, and custom grille patterns that match existing sightlines. The grille bars get installed on the interior side of the glass where possible, which keeps the exterior surface easier to clean after burn season when the ash settles on everything.

Oversized Glass Panels
When a South Bay homeowner wants a full-height fixed window facing the lake or a wide sliding glass wall across the back of a great room, we handle the engineering and the lifting. Oversized panels here need thicker glass to meet wind-load requirements, and the framing needs to be stiffer than a standard residential system. A 96-inch-by-72-inch impact-rated fixed panel with a reinforced frame typically runs $4,500 to $9,000 installed in South Bay. We’ll bring the crane if we need it, coordinate the permit, and make sure the sill is set at the right height above grade for flood resistance.

Trusted Brands We Service in South Bay
We’re an authorized installer for more than a dozen manufacturer lines, and in South Bay we heavily recommend PGT and CGI for impact-rated work because their laminated glass and reinforced frames are built for the Florida building code cycle this region enforces. Ply Gem comes up often for budget-conscious replacements where impact rating isn’t the controlling factor, and CWS fills the mid-range for commercial storefront. We keep common replacement parts stocked for these lines so a broken latch or sagging sash doesn’t mean a three-week wait for a part out of a warehouse. We service and replace all of them, and we’ll quote two or three lines side by side on paper so you can see the price difference in writing.
Common Custom Windows & Doors Problems We See in South Bay Homes
- Binding aluminum sliders from sugarcane ash. The burn season runs roughly November through April, and the fine particulate from those field burns works its way into window tracks and sliding glass door channels. If the tracks aren’t flushed and lubricated after the season ends, the rollers grind through the aluminum and the slider binds by July. We see it every year on homes along State Road 80.
- Fogged insulated glass from seal failure. Persistent ground-level humidity from Lake Okeechobee accelerates corrosion on the hardware that holds insulated glass units together. When the seal goes, moisture gets between the panes and you get that permanent haze. In South Bay’s climate, a low-quality seal can fog in as little as five years. A properly sealed unit with a registered warranty should last decades.
- Corroded sills and jambs on original single-pane aluminum. Those 1950s and 1960s jalousie windows that came with South Bay’s agricultural worker housing are not impact-rated and were never designed for this humidity level. The sills pit, the frames loosen, and the whole assembly leaks air and water into the wall cavity. Full replacement is the honest fix, and it usually cuts the electric bill noticeably.
- Water intrusion through standard door thresholds. When wind drives off the lake, water hits door thresholds at a lateral angle that code-minimum installations don’t anticipate. Without a flood-rated door pan and an elevated threshold sealed with marine-grade sealant, water ends up under the flooring and into the jamb. We rebuild these thresholds with the right materials, not the cheap pan from the box store.

What moves the price in South Bay specifically is the coastal-spec hardware and flashing. Stainless fasteners, flood-rated door pans, marine-grade sealant, and elevated thresholds add real cost to a job that an inland contractor wouldn’t include. The cheap spec might save you $300 to $1,500 per opening now, and cost far more than that within a decade when the hardware corrodes and the seals fail. We’ll give you a written line-item quote with the materials listed by name, and the estimate is free. Call (954) 280-4413 to schedule one.

FAQs - Custom Windows & Doors in South Bay
It pushes you toward reinforced aluminum, fiberglass, or vinyl frames with stainless steel hardware, and away from untreated wood or cheap aluminum. The lake drives constant ground-level moisture into every opening, and standard interior-grade hardware will corrode within a few years. We specify marine-grade finishes and stainless fasteners on every South Bay job, because we’ve seen what happens when someone doesn’t. Call (954) 280-4413 for a free estimate and we’ll walk you through the material options in your budget.
Yes. South Bay sits directly against the Herbert Hoover Dike system, and storm surge events can push water landward at angles that standard flood mitigation details don’t anticipate. That means flood-rated door pans, elevated thresholds, and corrosion-resistant hardware are non-negotiable here in a way they aren’t for most of Palm Beach County, including the neighboring towns. We pull permits and build to the current Florida Building Code flood provisions for every job in South Bay. Call (954) 280-4413 to schedule a free estimate.
Replacing jalousie windows with new impact-rated double-hung or casement units will eliminate the binding, and it’s the main reason South Bay homeowners make the switch. The binding comes from sugarcane ash and fine particulate that builds in the old jalousie tracks during burn season. New double-hung units have tighter tracks and better weatherstripping, and when you pair them with an annual track flush after the season ends, the binding stops. On a 1960s CBS home off Palm Beach Road, we replaced corroded original jalousie windows with impact-rated Andersen double-hungs, sealed the sills with marine-grade sealant, and the tracks stayed clear through the next burn season. Call (954) 280-4413 for an exact quote on your openings.
Fog between the panes means the insulated glass seal has failed, and in South Bay’s humidity it means the unit is doing almost nothing to insulate or block moisture. It’s not cosmetic. Once the seal goes, the argon or krypton fill leaks out and condensation becomes permanent. You can replace the glass pack, but if the frame is a decade old and already corroding at the sill, full door replacement is usually the better use of money. We’ll quote both options and let you see the numbers side by side. Call (954) 280-4413.
For a whole-home replacement with eight-to-twelve openings, expect to pay $2,000 to $6,000 more for the coastal-spec version. That’s the cost of stainless steel fasteners instead of galvanized, flood-rated door pans instead of standard ones, marine-grade sealant, elevated thresholds, and the additional flashing labor around each opening. The cheap inland spec fails here. We’ve seen it within five years, and the repair bill usually eats whatever the homeowner saved on the front end. Call (954) 280-4413 for a written quote that lists the materials by name, and a free estimate on your South Bay home.
