Why TruePane Windows & Doors Is South Bay’s Preferred Custom Windows & Doors Company
We started serving South Bay the way most of our customers found us: someone’s slider bound up after a burn, someone’s jalousie panes rattled through a storm, and a neighbor said the name TruePane. Dale Kessler founded this company in 2008 on the rule that if the pane is not true, the job is not done. Years of combined glazing heritage stands behind that rule, and the crews we send to South Bay are background-checked, uniformed technicians who measure every opening twice and quote manufacturer lines side by side on paper.
South Bay homeowners have told us the same thing for years: they want a company that answers the phone and honors the warranty without a fight. That is why we register both manufacturer warranty layers in writing, with durations stated, before the truck leaves the driveway. Our 90-Day Done Right Promise means if the work is not done right, we make it right. No paperwork, no arguing. We hire local, train apprentices into journeymen, and sponsor county fairs and church roof funds because we plan to be here in thirty years.
When you call TruePane for Custom Windows & Doors work, a live person answers 24 hours a day, 7 days a week. We are not a regional call center, and we never route you through a callback form. Most South Bay jobs are quoted and installed without a second appointment left hanging, and every estimate is line-item written so you see exactly what you are buying.
Our Custom Windows & Doors Services in South Bay
Custom Shape Windows
South Bay’s older CBS homes often have odd-sized openings from the original 1960s and 1970s frames: eyebrow arches over front doors, narrow vertical slits beside entryways, hexagons in gable ends. We build custom shape windows to fit those openings exactly, with impact-rated glazing and low-E argon fills that hold up to Lake Okeechobee’s humidity better than the original single panes ever did. A custom arch or radius window in South Bay typically runs $1,600-$3,400 installed, depending on frame material and glass package.

Impact-Rated Replacement for Original Sliders and Jalousies
The original aluminum jalousie and slider windows on South Bay’s 1950s-through-1980s housing stock were never built for the wind loads that still reach this far inland. Hurricanes tracking across the state arrive here with meaningful Category 1 sustained winds, and a single-pane jalousie offers about as much protection as a screen door. We replace those with impact-rated systems from PGT and CGI, quoted side by side on paper, with stainless steel track hardware specified for this climate. Impact-rated replacements in South Bay run $1,400-$3,800 per opening on average.

Architectural Grilles & SDLs
Simulated divided lites, or SDLs, give a South Bay home the look of individual panes without the energy loss of true divided light. We install factory-applied SDL grids inside impact-rated insulated glass units, so you get the farmhouse or mid-century look with a single sealed unit that will not collect sugarcane ash in individual pane joints. Applied interior and exterior grilles are also available. Grille and SDL work adds roughly $120-$280 per sash to the base window cost in South Bay.

Commercial Storefront Glazing and Curtain Wall Systems
For the small commercial buildings along Main Street and the agricultural service offices near US-27, we do storefront glazing and curtain wall systems built for wind-driven rain and ash-saturated air. Storefront glass replacement in South Bay starts around $1,800 per storefront section, and full curtain wall projects are quoted per square foot with engineering submittals included. These systems get the same Keystone Standard as every house we work on: both warranty layers registered in writing before we leave.

Trusted Brands We Service in South Bay
We are an authorized installer for more than a dozen manufacturer lines, including Andersen, PGT, CGI, ES Windows. For South Bay specifically, we recommend and stock parts for the lines that hold up best in lake humidity: ES Windows for custom architectural shapes, PGT and CGI for impact-rated replacements, and Andersen for full-frame residential rebuilds. Because we stock local parts and work directly with manufacturer reps, most South Bay replacement orders arrive faster than a homeowner ordering a single unit themselves.
Common Custom Windows & Doors Problems We See in South Bay Homes
- Black snow ash in tracks and weep holes: Fine particulate from sugarcane burns packs into window track channels and door weatherstripping, trapping moisture against aluminum frames. The result is sliders that bind shut and water that pools against the frame instead of draining.
- Fogged and failed seals from lake humidity: Persistent humidity off Lake Okeechobee accelerates seal failure in insulated glass units. We see fogged panes and lost argon fill in South Bay windows within five to eight years of installation, far sooner than in Palm Beach or Broward.
- Original single-pane aluminum jalousies with no impact rating: These leak air, rattle in wind, and offer no debris protection in a storm. Most South Bay homes we visit still have the original 1960s or 1970s frames in place.
- Binding sliding glass doors after burn season: Ash compacts into the bottom door track, and the door grinds against it every time you open or close. The fix is a full track flush and weep hole clearing, not a new door, but it takes a technician who knows what black snow is.
Pricing for Custom Windows & Doors in South Bay, FL
Here is what we see in South Bay, straight from our quote log:
| Project Type | Typical South Bay Range |
|---|---|
| Impact-rated single window replacement | $1,400 - $3,800 |
| Custom shape window (arch, radius, angled) | $1,600 - $3,400 |

What moves the number: glass package (clear vs. low-E argon vs. tinted), frame material (aluminum vs. vinyl vs. engineered wood), impact rating level, and how much the original opening needs reframing. The spec matters most in South Bay. Stainless steel hardware and marine-grade finishes cost more upfront: roughly 12 to 18 percent over standard inland specs. Cheap aluminum hardware here corrodes, pits, and fails. We will show you both numbers on paper so you can decide with your eyes open. Call (813) 320-9346 for a free, line-item estimate.

FAQs - Custom Windows & Doors in South Bay
Black snow is the fine ash that settles over South Bay when surrounding sugarcane fields are burned before harvest. It packs into window weep holes and door track channels, blocks drainage, traps moisture against aluminum frames, and causes sliders to bind. The fix is a full track flush and weep hole clearing, typically done as part of our maintenance check. Call (813) 320-9346 to schedule one before the next burn season starts.
Your sliders are likely packed with compacted sugarcane ash in the bottom track. The ash acts like sandpaper and blocks the weep holes that let water drain, so the sash grinds every time you open it. It is not a failed seal most of the time. It is a drainage problem. A technician who knows South Bay will flush the track and clear the weep holes first before recommending a more expensive repair.
Yes. Hurricanes that track inland across Florida still reach South Bay with sustained Category 1 winds, and the original single-pane jalousie and slider windows on most homes here offer no debris protection. Impact-rated glazing in South Bay runs about $1,400-$3,800 per window installed. The added cost is cheaper than boarding up every storm and far cheaper than the interior damage one broken window can cause.
Palm Beach gets sea breezes that cycle moisture away. Lake Okeechobee’s humidity sits over South Bay with nowhere to go, accelerating seal failure in insulated glass units and causing fogged panes within five to eight years here. That is why we spec low-E argon-filled units with stainless steel hardware as standard on South Bay jobs, not as an upgrade. It is the coastal-spec glass without the coastal price tag.
Despite being inland, South Bay’s humidity acts on aluminum frames the way salt air does on the coast, corroding hardware and pitting powder finishes. We recommend impact-rated aluminum frames with marine-grade finishes for strength, or engineered wood with a factory finish and stainless steel hardware for aesthetics. Vinyl is fine for budget-conscious single-story projects here as long as it is impact-rated. We quote all options side by side on paper so you can see the real price gap.
