Therma-Tru Window Replacement: The Fort Lauderdale Owner’s Guide

If you have a Therma-Tru window that won’t close square, has a fogged sash, or is leaking air around the frame, we stock and install replacement sashes and full-frame units matched to your series, with most Fort Lauderdale jobs running $350 to $1,100 installed per opening depending on size, glass package, and whether it’s a sash swap or full frame-out. We’re a call away at (954) 280-4413, and in most cases we can have a technician out the same week to measure, match the part, and get you a written quote. The way most homeowners find us is a window that worked fine for fifteen years and now suddenly binds in the corner or lets the afternoon heat pour in around the weatherstripping.

Therma-Tru built its name on entry doors, but their window lines – typically bundled with door packages or sold through builder supply houses – show up in plenty of Fort Lauderdale homes built from the early 2000s onward. The good news is the hardware and sash components are still serviceable. The catch is that without the right measurements and the right source, you can end up waiting three weeks for a part that doesn’t fit. That’s the problem we solve.

Which Therma-Tru Models This Applies To

Therma-Tru windows in our service area fall into two broad groups: awning and casement units that were sold as companion windows to Therma-Tru door packages, and a smaller number of single-hung and fixed picture units installed by tract builders. The single-hung and fixed units are usually straightforward. The casement and awning windows are where compatibility gets tricky, because Therma-Tru sourced different hinge and operator hardware across production years, and two windows that look identical from the outside can take entirely different sash assemblies.

Here’s the checkable detail most people don’t know: Therma-Tru stamps a manufacturing code on a small label on the top edge of the sash or the inside of the frame channel. That code tells us the series, the glass package, and the production year. Without it, we’re guessing. With it, we can match an OEM sash or spec a proper aftermarket equivalent the first time. For older units where the label has faded or been painted over, we measure the sash profile, the wall thickness of the vinyl or composite extrusion, and the operator mount spacing. We’ve done enough of these in Fort Lauderdale to know exactly what we’re looking at once the sash is out.

On the OEM versus aftermarket question, we’re straightforward: if your window is under the manufacturer’s warranty period and the failure is a covered defect, OEM is the right call and we’ll register the claim with you. If the window is ten or fifteen years old and the warranty has run, a quality aftermarket sash from a supplier we trust can match OEM fit and often exceed it on glass quality – a low-E upgrade on an older Therma-Tru is a real improvement in this climate. We’ll put both options on paper side by side so you see exactly what you’re buying and what each layer of warranty covers. TruePane Windows & Doors is an independent service provider; we’re not affiliated with Therma-Tru, but we service their products daily and know their quirks.

Signs Your Therma-Tru Window Replacement Is Failing

• Fog inside the glass pack. This is an upfront and settled cause: the edge seal has failed, the argon or air between the panes is gone, and Florida humidity has worked its way between the lites. You can’t dry it out, and once the seal is gone, the window’s insulating value is gone with it. The sash needs replacing.
• The crank or operator binds and the sash won’t seat evenly. On Therma-Tru casement and awning windows, this is usually a worn operator gear paired with hinge wear, and forcing the crank just compounds both. Once the sash doesn’t seat square against the weatherstripping, the window can’t do its job and the hardware keeps degrading.
• You can feel heat radiating through the glass in the afternoon. Fort Lauderdale sun is brutal on older single-pane and early low-E glass. If the sash frame is still square and the hardware is sound, a glass-pack replacement can bring the window back to modern energy performance without removing the whole frame.
• Water staining at the interior corners or along the sill. This points to a failing weatherstripping or a warped sash, and in a Florida coastal corridor, it’s the first sign that the window is no longer sealed against driven rain. Left alone, the frame behind it starts to suffer.
• The window simply won’t stay open or closed. A sash that drops or creeps has worn balance hardware or hinge failure. It’s annoying, but it’s also a safety issue if a second-story window decides to drop on its own while someone’s hands are in the opening.

Replacement Cost & What’s Included

In Fort Lauderdale, a Therma-Tru sash replacement with a standard insulated low-E glass pack typically runs $350 to $650 installed per opening, including the part, labor, and disposal of the old sash. A full frame-out replacement – required if the frame itself is warped, rotted, or out of square – runs $700 to $1,100 per opening on most mid-size windows and more if we’re upgrading to impact-rated glass or changing opening sizes. We give upfront pricing in writing and we hold to it. The quote you approve is the bill you pay, no surprise line items.

Every TruePane job is covered by the Done Right Promise, and under The Keystone Standard, we register both warranty layers in writing before the truck leaves your driveway. That means the manufacturer’s warranty on the sash or glass pack, and the duration of our workmanship guarantee, are on paper in your hand – not buried in fine print somewhere. It’s the way Dale Kessler has run this company since 2008.

DIY or Call Us?

There are honest checks you can do yourself: find the manufacturing label and take a clear photo of it, measure the visible glass and the overall sash width and height to the nearest eighth of an inch, and note which way the window opens and whether it’s left handed or right handed if it’s a casement. That information gets us most of the way to a correct match before we ever send a truck. What we don’t advise is pulling the sash off a Therma-Tru window to “get a better look.” Casement and awning sashes on these units sit under constant torque from the operator and hinges, and an unseated sash can drop or spring unexpectedly. If the window is on a second floor or over a walkway, it’s not worth the risk.

If it’s a simple single-hung sash you can lift straight out, some homeowners do handle their own measurements and we’ll supply the part. But if the operator binds, the hinge drags, or the sash doesn’t seat, call us at (954) 280-4413. We’d rather spend twenty minutes unpacking the quote than have a homeowner on a ladder fighting a window that’s fighting back.
