Therma-Tru Custom & Geometric Windows in Royal Palm Beach: What to Know First
Therma-Tru custom and geometric windows in Royal Palm Beach can be repaired, resealed, or replaced by TruePane Windows & Doors. We’re an independent Therma-Tru service provider, not a factory-authorized shop, which means we work for the homeowner, not the manufacturer’s warranty department. Most Therma-Tru custom and geometric window repairs run between $175 and $650 in Royal Palm Beach, depending on the size of the opening and whether we’re replacing glass, hardware, or the complete unit. This page is for homeowners who own Therma-Tru products and want straight answers about repair versus replacement before anyone quotes them a number. Call (386) 251-6745 and a live person answers, day or night.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds a solid entry door, and many Royal Palm Beach homes have their door-and-sidelight combinations, but the window products come with their own failure patterns after ten or fifteen years in Florida weather. Here’s what we see on custom and geometric units specifically:
- Geometric frame seal separation on radius-top units. The curved upper sash on a half-round or arch-top Therma-Tru window takes the brunt of afternoon sun on a west-facing Royal Palm Beach elevation. The sealant bond between the curved frame and the flat sill fails first along the spring line of the arch. We see this regularly in the Madison Green and Bella Terra neighborhoods. The fix is not caulking over it; it’s removing the sash, cleaning the channel, and resetting with a marine-grade sealant rated for the expansion rates we get between February and August.
- Fogged insulated glass on trapezoid and triangle units. Therma-Tru custom shapes use bent or cut insulated glass units, and the edge seal on a non-rectangular IGU fails faster than what you’d see on a standard rectangle. The reason is simple: the perimeter-to-area ratio is higher, so there’s proportionally more seal edge exposed to humidity. Replacing the IGU runs less than a full window replacement and the glass clarity is restored permanently when we order the replacement through a glass fabricator who cuts to the exact template, not an approximation. A rebuilt sash with OEM hardware and fresh seals costs less than you’d think, and if the frame itself is square and solid, there’s no reason to tear it out.
- Operator crank hardware wear on casement-style custom units. Large radius or oversized Therma-Tru casement windows put more torque on the crank mechanism than factory testing accounts for. In Royal Palm Beach, the salt air accelerates corrosion on the gear teeth. When the crank slips, the window won’t seat fully, which lets humid air in and strains the locking points. We replace the entire operator assembly, not just the handle, so the new gear mesh lasts. We keep several Therma-Tru hardware kits stocked because this is a common call.
- Frame racking on oversized openings. A Therma-Tru window set into a wall that has settled slightly in Royal Palm Beach’s sandy soil will bind at the corners. You’ll notice it when the sash refuses to close flush in July, then works fine in January. This is not a Therma-Tru defect; it’s a frame-tolerance issue. We true the frame, shim it properly, and reset the unit so the reveal is even on all four sides. Out-of-square is a Royal Palm Beach reality, but it is fixable without replacing the window.
Our Therma-Tru Custom & Geometric Windows Process
Every job starts the same way, whether it’s a small rattling transom or a full geometric replacement:
- 1
The call. You reach a live person, not a recording. We ask about the symptom, the age of the unit, and roughly where the window sits on the house. If it sounds like an emergency, we’ll tell you what to watch for before we get there.
- 2
The site visit. We measure the opening twice. Every opening. On custom and geometric work, we cut a template of the existing sash so the replacement glass or frame matches the curve or angle exactly. No guessing, no “close enough.”
- 3
The parts decision. We quote OEM Therma-Tru parts when the warranty is active or the homeowner wants original. We quote equivalent aftermarket parts when the OEM option is discontinued or the lead time is unreasonable. Side by side, on paper, so you see the difference before you spend a dollar.
- 4
The work. We remove the old unit or component, correct any frame alignment issues, and set the new piece. Sealant is tooled, not smeared. Screws are set to spec. We don’t rush a cure time.
- 5
The test. Water test on the exterior, air test on the interior, and a full open-close cycle on every operable unit. If it binds, we adjust. If it leaks, we redo it before we leave.
- 6
The paperwork. We register the manufacturer warranty layers in writing before the truck leaves the driveway. We document what was done, what was used, and how long it’s covered. Then we clean the work area and walk the job with you.
What Therma-Tru Custom & Geometric Windows Costs in Royal Palm Beach
Every Royal Palm Beach job prices out differently because no two custom openings are the same, but these numbers cover what we see most often:
- Glass-only replacement (fogged IGU, cracked pane, arch-top or triangle unit): $225 to $525
- Hardware replacement (crank assembly, locking mechanism, hinges on custom units): $140 to $350
- Complete custom or geometric window replacement (standard sizes): $700 to $1,600
- Complete oversized or radius-top replacement (wider than 60 inches or true arch): $1,400 to $2,800
What moves the price: size, shape complexity, glass package (impact-rated, low-E, double versus triple), and whether the existing frame is salvageable. Elevated or second-story work adds labor. Fixed geometric windows cost less to replace than operable ones. Call (386) 251-6745 for a line-item estimate. It’s free, and the numbers we quote are the numbers you’ll pay.
Why Royal Palm Beach Homeowners Call TruePane Windows & Doors for Therma-Tru Work
TruePane Windows & Doors was founded by second-generation glazier Dale Kessler, who grew up off Crestwood Boulevard in Royal Palm Beach and has spent the better part of three decades measuring, setting, and sealing windows and doors across Palm Beach County. We’ve been serving local communities since 2008 through a heritage of craft and community commitment. Every job is covered by the Done Right Promise: if it’s not done right, we make it right, with no paperwork fights and no arguing. The Keystone Standard means both manufacturer warranty layers are registered in writing before we leave. We also carry PGT, CGI, CWS, and ES Windows, so when a Therma-Tru unit is too far gone, you’ll get a real comparison, not a sales pitch. Our technicians are background-checked, uniformed, and they measure twice. If the pane is not true, the job is not done.
FAQs
Yes. We cut a template of the existing sash and order replacement insulated glass through a fabricator who cuts to the exact curve or angle. This works for fogged units, cracked glass, and double-pane failures. Call (386) 251-6745 to schedule a measurement.
No. Federal law protects your right to independent service. As an independent Therma-Tru service provider, we source OEM parts when appropriate and register all warranty paperwork in writing, so your coverage stays intact. We’ll tell you honestly what falls under warranty and what doesn’t, before we do any work.
Repair makes sense when the frame is square, the glass is the only failed component, and the hardware is available. Replacement makes sense when the frame has racked, the seal has failed repeatedly, or the unit is nearing twenty years old. We’ll walk you through the math on the site visit and give you both numbers. Call (386) 251-6745 for a free estimate and we’ll tell you straight.
Most standard custom shapes are removed and replaced in a single visit, typically four to six hours. Oversized or radius-top units may require a template-to-fabrication lead time of one to two weeks. We’ll give you a firm schedule when we measure. Call (386) 251-6745 to book.
Yes. We install and service impact-rated Therma-Tru products and follow Florida Building Code requirements for Palm Beach County. If it is not sealed right, the next storm will tell you. That’s why we water-test every unit before calling the job done.
