1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.

Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

Therma-Tru Window Replacement: The Fort Lauderdale Owner’s Guide
Therma-Tru window replacement in Fort Lauderdale typically runs $340-$780 per opening for sash, frame, or hardware failure, depending on whether you’re dealing with a fixed picture unit or an operating casement or double-hung. We stock Therma-Tru-compatible sashes, balances, and weatherstrip kits on our trucks, and most replacements we measure in the morning are installed by afternoon. Most owners discover the problem when a window that used to glide starts sticking, or when they spot condensation between panes that won’t wipe away.
Which Therma-Tru Models This Applies To
Therma-Tru window lines break into three main families you’ll see in Fort Lauderdale homes built between 2010 and 2022: the Classic-Craft and Fiber-Classic series (typically casement and awning units with wood-composite frames), the DuraMax vinyl line (double-hung and slider configurations common in Broward County subdivisions), and the limited aluminum-clad commercial line found in Las Olas corridor townhomes. The critical compatibility gotcha is the balance system: Classic-Craft casements from 2015-2019 used a proprietary 3/8-inch spiral-tube balance that Therma-Tru later superseded with a 7/16-inch version. Order the wrong diameter and the sash won’t hold position.
We identify the correct part by the etched NFRC label in the glass corner (lists the CPD number), the stamped code on the balance tube if accessible, and the sightline measurement of the visible glass against the frame. OEM Therma-Tru parts ship from Ohio with a 10-14 day lead time; we also source certified aftermarket equivalents from AmesburyTruth and Caldwell that match the original specs and carry the same 10-year finish warranty. For impact-rated units, we stick with OEM - the Miami-Dade Notice of Acceptance tracing matters for your windstorm inspection.

Before
AfterSigns Your Therma-Tru Window Replacement Is Failing
- Condensation trapped between glass panes. The insulated glass unit (IGU) seal has failed, releasing the argon fill and allowing Fort Lauderdale’s humid air to migrate inside. The glass pack needs replacement; cleaning the exterior won’t reach it.
- Sash drops or won’t stay open. The spiral balance has lost tension or the pivot shoe has cracked. In salt-air environments like Coral Ridge or Harbor Beach, we’ve seen balance corrosion accelerate this failure by 30-40% versus inland installs.
- Visible frame warping or vinyl chalking. UV exposure and thermal cycling have degraded the frame substrate. Therma-Tru’s vinyl formulations hold up well, but south-facing units without overhangs typically show this at 12-15 years in Broward County.
- Air infiltration at the meeting rail or sill. The compression weatherstrip has flattened or the interlocking sash rail has worn. We check this with a smoke pencil during survey; a 1/16-inch gap at the meeting rail can double your cooling load.
- Hardware operates with grinding or the lock won’t engage. The multipoint lock mechanism or hinge has corroded, often from rain sheet-flowing over a failed sill pan. Left unaddressed, the misalignment stresses the frame corners.
Replacement Cost & What’s Included
| Component | Typical Range (Fort Lauderdale) | What’s Included |
|---|---|---|
| IGU (glass-only replacement) | $340-$520 | Measured survey, tempered or annealed IGU per spec, argon fill, 10-year seal warranty |
| Sash pack (frame + glass) | $480-$680 | OEM or certified equivalent sash, balance hardware, installation, disposal |
| Full frame replacement | $620-$780 | Complete unit removal, rough opening inspection, new frame, insulation, trim, photo record |
| Hardware/lock set | $180-$290 | Multipoint lock or hinge set, adjustment, lubrication, operation test |
What drives the range: unit size, floor level (third-story ladder work adds time), stucco or drywall interior returns, and whether the original install left a reusable sill pan. We pull permits when the replacement changes the opening dimensions or the impact rating; most sash-in-frame replacements don’t require it. Every quote is the measured survey you keep, stamped under Haven Clause 1: Have it in writing. The 365-Day Done Right Promise covers labor and materials; the manufacturer’s warranty runs concurrent on the product itself.
DIY or Call Us?
There’s a short list of checks any owner can make safely. Verify the lock is fully engaged - a half-thrown multipoint lock mimics frame failure. Run your hand along the frame perimeter to locate drafts; mark them with tape for our survey. For double-hung units, check that both sash locks meet at the same height; a tilted sash usually means a slipped balance shoe.
Where DIY goes wrong: removing a sash with a loaded spiral balance without pinning the tube first can release stored tension abruptly. The balance shoe rides in a jamb liner under compression; without the right spreader tool, you’ll crack the vinyl. And if you’re dealing with an impact-rated unit, disturbing the glazing tape or frame seal voids the Miami-Dade certification. We carry pinned balances, spreader bars, and sightline gauges on every truck. Call (754) 666-7478 to schedule your free estimate - we’ll measure twice, write the price, and show you the photo record when we’re done.
FAQs
Vinyl and composite frames typically perform 20-25 years with proper installation; the IGU seal is usually the first failure at 12-18 years in our coastal climate. Salt air, south exposure, and absent overhangs pull that toward the lower end. Call (754) 666-7478 for an exact quote - estimates are free.
Failed IGUs cannot be repaired; the seal is permanent and the desiccant inside the spacer is saturated. Single-pane cracks can sometimes be stabilized temporarily, but the thermal performance is gone. Replacement is the only fix that restores the original U-factor and SHGC. Call (754) 666-7478 for an exact quote - estimates are free.
A sash swap in an existing frame takes 45-90 minutes per opening; a full-frame replacement runs 3-4 hours including trim and seal work. We schedule one full day for up to four openings, with the measured survey completed beforehand so there’s no discovery delay. Call (754) 666-7478 for an exact quote - estimates are free.
We carry common sash sizes, balance assemblies, and weatherstrip profiles for Therma-Tru’s DuraMax and Classic-Craft lines; specialty sizes and impact-rated IGUs order overnight from our Miami distributor. We don’t start work with a parts chase - Haven Clause 2 means we arrive on schedule with what the measured survey specified. Call (754) 666-7478 for an exact quote - estimates are free.
Sonia Raman keeps a running list of every product failure she’s seen and what caused it. That list includes a lot of Therma-Tru units that were ordered from a catalog without a field measurement - a 1/4-inch frame tolerance that works in Ohio swells shut in Fort Lauderdale’s humidity. Measure it right the first time or measure it twice on someone else’s dime.
