Therma-Tru Energy-Efficient Windows in Palm Beach Gardens: What to Know First
We provide independent Therma-Tru energy-efficient window service and replacement in Palm Beach Gardens, with most glass upgrades and sash repairs completed in a single visit. A typical Therma-Tru Low-E insulated glass replacement runs $380 to $740 per window depending on glass package and size, and a full-frame energy-efficient replacement starts around $900 per opening. As an independent Therma-Tru service provider, we’re not bound to a single parts pipeline - we source what actually fits and stands up to South Florida humidity. This page is for homeowners who own Therma-Tru windows, have felt the afternoon heat pushing through the glass, and want straight answers on what to fix, what to replace, and what it costs. Call (772) 794-8169 and a live person answers, day or night.
How Therma-Tru Products Fail - and How We Fix Them
- Fogged glass on Classic-Craft and Benchmark units. Therma-Tru’s entry-level and mid-range door and window lines use dual-pane insulated glass units that eventually lose their gas fill and seal. In Palm Beach Gardens, the combination of high humidity, salt air, and afternoon thermal swings pushes those seals harder than most climates. The tell is condensation you can’t wipe away. We replace the IGU with Low-E argon-filled glass, not a cheap single-pane swap, and the new unit gets registered under its own warranty.
- Warped or bowed sashes on Therma-Tru casement and awning windows. We see this most often on east-facing walls where the morning sun hits hard. The vinyl or composite sash bows almost imperceptibly, the weatherstripping loses contact, and the homeowner feels a warm draft exactly at the meeting rail. We re-align the sash, replace the weatherstripping with a heavier-gauge section, and if the bow is too far gone, we quote a full sash replacement before talking whole-window replacement.
- Failed glazing tape on Therma-Tru fixed and picture windows. Therma-Tru uses glazing tape as a primary seal on some fixed units. After ten to fifteen years in Florida sun, that tape dries, shrinks, and pulls away from the frame edge. You’ll see a faint gray line or feel a subtle draft around the perimeter. We pull the old unit, clean the frame channel properly, and reset the glass with fresh tape and a perimeter bead of compatible sealant. It’s tedious work most contractors skip, but it’s exactly where leaks start.
- Spring balance failures on Therma-Tru double-hung windows. Double-hung units ride on spring balances inside the jamb. When one fails, the sash sags to one side, tilts, or won’t stay up. The gap at the top lets conditioned air pour out and damp air in. We replace both balances as a pair, even if only one failed, because the other is usually within weeks of the same fatigue point. New balances restore a clean compression seal at the top and bottom rails.
- Low-E coating degradation on early-2000s Therma-Tru units. This one is specific to age. Early Therma-Tru Low-E coatings can develop a hazy or slightly bronzed film after twenty years of UV exposure. It looks like the glass is dirty, but cleaning won’t touch it. The coating itself is breaking down. The energy-efficiency drop is measurable - the glass starts transmitting noticeably more solar heat. A replacement IGU with current-generation Low-E restores the original thermal performance, often better than the original.
Our Therma-Tru Energy-Efficient Windows Process
- 1
Call and describe what you’re seeing. A live person answers at (772) 794-8169. We’ll ask what the window is doing - fog, draft, sag, heat - and which Therma-Tru line it’s from if you know. Most calls take under ten minutes.
- 2
Two measurements before any commitment. Our technician measures the rough opening and the existing sash twice, checks the square of the frame, and notes any signs of water intrusion or frame rot. If the frame is off-square, we tell you before we quote anything.
- 3
Parts decision - OEM or quality aftermarket, on paper. For Therma-Tru units still under warranty, we use OEM parts so the warranty stays intact. For older units out of warranty, we quote both OEM and reputable aftermarket options side by side on paper, with the warranty duration stated for each. You see exactly what you’re buying.
- 4
The repair or replacement, completed same day. Glass replacement, sash repair, and balance swaps are typically done in one visit. Full-frame energy-efficient replacements take longer, but we set a schedule and keep it.
- 5
Testing before we leave. We run the sash through its full travel, check the seal with a thermal probe where applicable, and verify the lock engages cleanly. If the window doesn’t close true, we don’t call it done.
- 6
The Keystone Standard, in writing. Every warranty layer gets registered in writing before the truck leaves your driveway. Durations stated, no fine print you’ll fight over later. That’s our standard on every Therma-Tru job.

What moves the price: glass package (standard Low-E versus high-performance argon-filled or tinted), sash count, frame condition, and whether the work is a repair versus full replacement. Every quote is a fixed written price before we start. Call (772) 794-8169 to schedule a free estimate - no surprises on the bill.
Why Palm Beach Gardens Homeowners Call TruePane Windows & Doors for Therma-Tru Work
We’ve been doing fit-and-seal work on South Florida windows and doors since 2008, and Dale Kessler founded TruePane in 2008 on a rule that still hangs on the whiteboard: if the pane is not true, the job is not done. Our technicians are background-checked, uniformed, and trained for the specific failure modes of Therma-Tru units in this climate - they know what a failing glazing tape looks like and they know when a sash is worth saving. If the repair doesn’t make sense, we’ll quote the Therma-Tru replacement honestly and put the numbers next to a PGT, CGI, CWS, or ES Windows option so you can compare. Every job carries the Done Right Promise: coverage in writing, no arguing. A live person answers the phone 24 hours a day, 7 days a week. You’ll talk to someone who knows windows, not a call center.
FAQs
Therma-Tru’s glass warranty varies by line and year, but most insulated glass unit failures are covered for 10 to 20 years on the seal. The catch is proof of purchase and proper installation records. We register both warranty layers in writing before we leave the driveway, which makes a claim far easier to process if an issue comes up. Call (772) 794-8169 and we’ll help you determine what your specific Therma-Tru line covers and what the fix costs if it doesn’t.
In most cases, yes. Fogged glass, failed balances, worn weatherstripping, and degraded glazing tape are all repairable without touching the frame. We only recommend full-frame replacement when the frame itself is water-damaged, structurally off-square, or so aged that the repair cost approaches the cost of a new ENERGY STAR unit. We’ll show you the numbers both ways before any work starts.
Most common Therma-Tru parts - glass units, sash components, balances - are available through our supplier network within three to five business days. Non-stock or discontinued items can take longer, and we’ll tell you the lead time upfront before you commit. If the part is discontinued and no longer available, we’ll quote a compatible replacement and explain the difference.
If the frame is sound, repairing the glass package and seals usually restores the original energy performance at a fraction of replacement cost. The real question is whether the current glass meets today’s ENERGY STAR standard for South Florida. If your Therma-Tru unit is fifteen years old or older, a replacement with current Low-E glass often pays for itself in cooling savings within five to seven years. We’ll run the numbers with your actual square footage and exposure.
Yes, when the scope requires it. Full-frame replacements and structural work get permits pulled and inspections passed. Glazing repairs and sash work typically don’t require permits, but we’ll tell you if your specific job does. If it is not in the written scope, it is not in the price - and if it is in the price, we stand behind it.
