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 Installation: The Lauderdale Lakes Owner’s Guide
Therma-Tru window installation in Lauderdale Lakes typically runs $340-$780 per opening depending on series, size, and whether the existing frame is preserved or replaced. We stock Therma-Tru-compatible frames, sashes, and hardware for same-day survey and written quote under Haven Clause 1. Most Lauderdale Lakes homeowners discover a problem when the sash won’t stay open, they feel air moving at the lock rail, or they spot water staining the drywall beneath the jamb after a summer storm.
Which Therma-Tru Models This Applies To
Therma-Tru window lines divide into two categories that matter for installation: the Classic-Craft and Fiber-Classic series, which use pultruded fiberglass frames with specific jamb depths of 4-9/16″ or 6-9/16″, and the Smooth-Star and Benchmark vinyl lines with 3-1/4″ or 4-9/16″ profiles. The critical compatibility gotcha in Lauderdale Lakes is that Classic-Craft sashes from 2015-2019 used a proprietary interlock geometry that doesn’t seat into post-2020 frame extrusions. We’ve found this mismatch on three Oriole Gardens retrofits where a homeowner ordered their own “compatible” sash and the weatherstrip channel sat 3/16″ proud of the frame leg.
To identify your part, check the etched code in the glass corner (format: TT-YY-MMDD-PLANT) or the silver AAMA label inside the top jamb. We carry both OEM Therma-Tru components and quality aftermarket equivalents from CWS and ECO Window Systems where the spec matches. For impact-rated openings in Lauderdale Lakes, we default to OEM because the HVHZ certification trace matters for your wind mitigation form.
Before
AfterSigns Your Therma-Tru Window Installation Is Failing
- The sash drifts or slams shut. This usually means the balance shoe or coil spring has lost tension. In Therma-Tru double-hungs, the balance is concealed in the jamb liner, and once the spring corrodes from Lauderdale Lakes humidity, the friction adjustment can’t compensate.
- Visible water at the sill or drywall below. The weep channels in Therma-Tru vinyl frames clog with salt and pollen faster than inland markets. Water backs up, crosses the sill dam, and finds the rough opening. We document this with frame readings and photos for the customer record.
- Lock won’t engage or pulls the sash out of square. The keep and cam on Therma-Tru units are zinc-diecast, and after seven to ten years of South Florida UV and salt air, the plating fails and the cam rounds off. The lock still looks fine, but it no longer draws the meeting rail tight.
- Condensation between glass panes. The seal on the insulated glass unit has failed. Therma-Tru IGU warranties run 20 years on glass, but the labor to swap the sash is not covered. We measure the daylight opening and order the replacement IGU to the exact 1/8″ - if the measurement isn’t written down, it doesn’t exist.
- Frame corner gaps or caulk separation. Thermal expansion in aluminum-clad Therma-Tru units loosens the mechanical corner keys. This is structural; caulking over it hides frame movement that will eventually crack the glass.
Replacement Cost & What’s Included
Installed pricing for Therma-Tru window work in Lauderdale Lakes breaks down as follows:
| Scope | Price Range |
|---|---|
| Sash replacement (IGU or sash pack) | $340-$520 |
| Full frame replacement, standard size | $580-$780 |
| Hardware set (lock, keep, lift rails) | $140-$220 |
| Jamb liner / balance replacement | $280-$420 |
The range reflects three variables: whether we preserve the existing frame and trim (less), whether the opening requires rot repair or flashing replacement (more), and whether the unit is impact-rated with laminated glass. Every quote is line-itemed and written before work starts. The price on the measured survey is the price on the invoice. Our 365-Day Done Right Promise covers labor and installation materials; manufacturer defects go through Therma-Tru’s warranty channel, which we handle as part of the job.
DIY or Call Us?
An owner can safely check three things: confirm the model code from the label, verify the sash size with a tape measure across the daylight opening, and clear weep holes with a piece of wire. Beyond that, Therma-Tru window work carries real injury risk. The concealed balance springs in double-hung units are under tension; releasing them without a brake tool sends hardware into the frame cavity or toward your face. Impact-rated sashes weigh 40-60 pounds and require two points of support during removal. We’ve been called to Lauderdale Lakes jobs where a homeowner cracked the IGU trying to force a sash past a swollen jamb liner in August humidity.
We carry Therma-Tru-compatible balances, sash locks, and jamb liners on the truck. Call (754) 240-8381 to schedule your free estimate. We’ll measure, write the scope, and leave you with the document.
FAQs
Properly installed Therma-Tru fiberglass frames last 25-30 years in South Florida; vinyl lines typically need hardware or sash replacement at 12-18 years due to UV and salt-air fatigue on seals and balances. The IGU seal is usually the first failure point, not the frame itself. Call (754) 240-8381 for an exact quote on your unit - estimates are free.
Hardware, balances, and IGU swaps are repairs that preserve the frame. If the frame leg is cracked, the corner key has failed structurally, or the rough opening shows rot, replacement is the only fix that passes inspection. We document both options with photos and a written scope so you can decide. Call (754) 240-8381 for a free second opinion on any estimate.
A sash or hardware replacement takes 90-120 minutes per opening. Full frame replacement with trim and interior finish runs 4-6 hours. We schedule by the job, not by the hour, and arrive with the part already verified against your measured survey. Call (754) 240-8381 to book.
We stock Therma-Tru-compatible balances, jamb liners, sash locks, and keepers. IGU replacements and full sashes are ordered to the measured spec and typically arrive in 5-7 business days. We do not stock every Therma-Tru SKU; we stock what fails most often in Lauderdale Lakes conditions and order the rest to exact size. Call (754) 240-8381 to confirm availability for your model.
