AfterTherma-Tru Custom & Geometric Windows in Fort Lauderdale: What to Know First
We install, replace, and service Therma-Tru custom and geometric windows throughout Fort Lauderdale as an independent Therma-Tru service provider - meaning we work on the product line every week, but we’re not a factory arm, so our recommendations don’t bend toward one series over another. A typical Therma-Tru shaped-window job in Fort Lauderdale runs $900 to $3,200 depending on size, glass package, and whether the frame needs full replacement or a glass-only swap. Most of our Therma-Tru calls are diagnosed and quoted in one visit, with installation scheduled inside of two weeks. If you own a Therma-Tru arched or geometric window that’s fogged, binding, or leaking, call (954) 280-4413 - a live person answers, and the estimate is free.
This page is written for the homeowner who’s had a Therma-Tru window long enough to know it’s not a quick swap at the big-box store. You want someone who can read the etching, match the profile, and tell you whether that radius window is worth saving or should be replaced outright. That’s the work we do.
Key Takeaways:
- We service Therma-Tru custom and geometric windows as an independent provider - no factory bias, no one-line-only pitch.
- Most Therma-Tru shaped-window jobs in Fort Lauderdale fall between $900 and $3,200.
- OEM glass packs exist for many Therma-Tru radius units, but some legacy shapes require custom fabrication - we walk you through the trade-off before you spend a dime.
- Both warranty layers get registered in writing before our truck leaves your driveway.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds a solid door, but their window lines - particularly the shaped and geometric units - have failure patterns we see repeated across Fort Lauderdale’s coastal corridor. Here are the five we run into most often, named plainly.
- Fogged insulated glass in radius and arch-top units. We see this most on older Therma-Tru Classic-Craft and Smooth-Star transom windows, the half-round and elliptical units over entry doors. The seal fails at the bottom curve where water sits after a South Florida downpour, and the argon or krypton fill escapes through the primary seal. The fix is a glass-pack replacement, not a full frame tear-out. We measure the radius to the sixteenth of an inch, order the pack, and reset it with fresh glazing tape and a proper shim pack. The frame stays; the glass gets new life.
- Binding sashes on oversized geometric openings. A trapezoid or octagon window in a gable end takes more wind load than a standard rectangle, and the frame can rack slightly over time - especially on homes built before 2001 when hurricane anchoring was less strict. We see this on Therma-Tru Prisma and Signature series shapes. The sash jams in the corner, the operator strips, and the homeowner assumes the window’s dead. Often we can true the frame, replace the operator, and get another decade out of it. If the frame’s out of plane beyond our tolerance, we’ll tell you straight and quote replacement.
- Weeping-system clogs on radius-bottom units. Therma-Tru shaped windows have drainage channels milled into the bottom rail. In Fort Lauderdale, those channels fill with silt, pollen, and the fine sand that blows off the beach. When they clog, water backs up into the frame and finds its way inside. The fix is methodical: clear the weeps, flush the channels, check the weatherstripping, and reseat the sash. It’s a one-visit job when caught early, and it’s one of the most common Therma-Tru repairs we make in neighborhoods like Victoria Park and Rio Vista.
- Failed glazing tape on fixed geometric picture windows. The adhesive bond on perimeter glazing tape breaks down in sustained heat and humidity - Fort Lauderdale gets both in quantities that test any sealant. We see it on Therma-Tru fixed units, especially octagons and ellipses installed without adequate shading. Water creeps in at the top corner, stains the drywall, and the homeowner thinks the roof’s leaking. We pull the glass, clean the frame, apply new bedding, and the leak stops.
- Operator and hinge hardware wear on casement and awning shapes. Therma-Tru’s shaped casement windows - the arched-top and springline units in their custom program - use multi-point hardware that wears unevenly under coastal salt air. We replace the operator arms, hinges, and locks with spec-matched parts, and we adjust the sash so it closes tight against the weatherstripping. This is the difference between a window that seals and one that whispers air conditioning into the yard.
Our Therma-Tru Custom & Geometric Windows Process
Here’s how a Therma-Tru job moves from your first call to the final walkaround. Dale Kessler’s rule applies at every step: if it is not right on paper, it will not be right on the wall.
- 1
Call and talk to a person. You reach a live technician, not a voicemail tree. We ask what the window’s doing, when it started, and what shape it is. Most homeowners don’t know the model number - that’s fine. We figure it out on site.
- 2
On-site measurement and diagnosis. A background-checked, uniformed technician arrives on schedule, measures every opening twice, and reads the glass etching to identify the series and glass package. We check the frame for true, the weeps, the hardware, and the seal.
- 3
Parts decision on paper. We show you the options side by side: OEM Therma-Tru glass pack or frame component, versus a quality aftermarket equivalent when OEM is discontinued or back-ordered. You see the price, the lead time, and the warranty difference before you choose. No surprises after the fact.
- 4
The work. We replace the glass pack or the full unit, reseat the frame, re-bed the glazing, and set the sash so it closes square. Most Therma-Tru shaped-window jobs are completed in a single visit. Replacement of a full geometric unit is usually one day on site.
- 5
Test and walkaround. We run the window through its full range of motion, check the seal, and show you the result. If it doesn’t pass our standard, we address it before we leave.
- 6
Warranty registration. Both manufacturer warranty layers are registered in writing before the truck leaves the driveway. You get the durations in your hand, and our Done Right Promise covers the workmanship.
What Therma-Tru Custom & Geometric Windows Costs in Fort Lauderdale
Therma-Tru work is priced by the opening, the glass package, and whether we’re saving the frame or replacing it. Here’s what we typically see in Fort Lauderdale:
- Glass-pack replacement, standard half-round transom: $450 to $900 installed.
- Glass-pack replacement, large elliptical or arch-top unit: $800 to $1,600 installed.
- Full frame replacement, standard geometric shape (octagon, trapezoid): $1,400 to $2,800 installed, depending on glass and structural anchoring required.
- Custom radius or oversized geometric unit, fabricated to order: $2,200 to $4,500 installed.
What moves the price: glass package (impact-rated adds cost but may be required by code in certain zones), whether the frame’s salvageable, access (second-story or scaffold work), and whether the existing opening needs structural correction. We quote fixed pricing before work starts - no change orders, no surprises. Call (954) 280-4413 for an exact number on your window. The estimate is free.
Why Fort Lauderdale Homeowners Call TruePane Windows & Doors for Therma-Tru Work
TruePane Windows & Doors was founded in 2008 by Dale Kessler, a second-generation glazier who grew up in Sailboat Bend watching his father reseal jalousie windows in the humidity - which, Dale will tell you, is more or less how he ended up in the trade. The company carries years of community service through that family heritage, and the founding rule on the whiteboard hasn’t changed: if the pane is not true, the job is not done.
Every Therma-Tru job is covered by our Done Right Promise and The Keystone Standard - both manufacturer warranty layers registered in writing, durations stated, before we pull off the driveway. If it’s not done right, we make it right. No paperwork fights, no arguing. And because we’re authorized installers for more than a dozen lines including PGT, CGI, CWS, and ES Windows, we can put a true comparison in front of you when a Therma-Tru unit isn’t worth saving. A live person answers the phone 24 hours a day, 7 days a week. That’s not a marketing line - it’s how we’ve operated from the start.
FAQs
No - we’re an independent Therma-Tru service provider in Fort Lauderdale. That independence matters because we’re not obligated to push one product line over another. We tell you what your window needs, not what a factory rep wants sold. That said, we work with Therma-Tru parts and glass packs regularly, and we know their series well enough to diagnose problems by sight.
In most cases, yes. We match the profile, the glass etching, and the color as closely as the current Therma-Tru catalog allows. For legacy shapes that are no longer in production, we fabricate to match through our custom shop. Call (954) 280-4413 and we’ll tell you what’s possible for your specific window.
No. We quote fixed pricing before work begins. The only way a price changes is if we open the wall and find something structural that couldn’t be seen from the outside - and we would never proceed without showing you what we found and getting your approval in writing. Our reputation in Fort Lauderdale is built on a square deal.
A standard glass-pack replacement is usually installed within one to two weeks. Fully custom geometric fabrication runs three to six weeks depending on the radius and glass package. We’ll give you a straight timeline when we quote, and we’ll hold to it.
When the job requires it - which depends on scope and whether we’re changing the opening size - we pull the permit and manage the inspection. For glass-only replacements in existing frames, no permit is typically required. We’ll tell you exactly what your job needs before we start.
If you have a Therma-Tru custom or geometric window that needs attention in Fort Lauderdale, call (954) 280-4413. A live person answers. The estimate is free, the quote’s in writing, and the work is done right.
