Therma-Tru Energy-Efficient Windows in West Palm Beach: What to Know First

Therma-Tru energy-efficient window service in West Palm Beach typically runs $145 to $385 per window for glass replacement, seal repair, and weather-sealing work, with full replacement units starting around $950 installed. Most Therma-Tru jobs are completed in a single visit, and we carry the common replacement glass specs and hardware on the truck. As an independent Therma-Tru service provider, we handle the energy-performance repairs and replacements on doors and sidelites that most general contractors in the area won’t touch. If you own a Therma-Tru entry system and your energy bills have crept up or you feel a draft near the glass, this page tells you what’s actually wrong, what it costs to fix, and what it takes to do it so it stays fixed. Call (561) 264-1279 and a live person answers, day or night.

Key takeaways:

• Therma-Tru is a door company first - their glass packages are sourced from third-party insulated glass fabricators, which means replacement glazing is widely available and rarely requires OEM-only parts.
• Most energy loss on Therma-Tru units in West Palm Beach comes from failed IG seals, worn weatherstripping, or warped door slabs - not the glass coating itself.
• We register both manufacturer warranty layers in writing before the truck leaves your driveway, and back every job with our Done Right Promise.

How Therma-Tru Products Fail - and How We Fix Them

Therma-Tru builds a solid door slab. The energy-efficient glass packages in their systems fail in predictable ways here in Florida, and we’ve seen every one of them. Here’s what actually shows up in West Palm Beach homes:

• Fogged insulated glass on Classic-Craft and Fiber-Classic doors. This is the most common call we get. The seal between the two panes fails, humid Florida air gets pulled into the airspace, and the glass clouds over. Once the seal is breached, the argon gas is gone and the unit’s insulating value drops by roughly half. We measure the opening, order a new insulated glass unit matched to the original Low-E spec, and set it with fresh glazing tape. The door slab stays. The glass is what gets replaced.
• Draft from the seal sweep on Smooth-Star door bottoms. Smooth-Star is Therma-Tru’s mid-tier fiberglass line, and its factory door-bottom sweeps compress over time in the heat. Once the sweep flattens, humid outdoor air flows straight under the door. We replace the sweep with a heavy-duty adjustable version that maintains contact across the full width of the threshold, and we check the door’s reveal with a straightedge while we’re at it. A door that sags even a quarter inch will keep eating sweeps until the hinges are corrected.
• Warped door slabs on full-lite entry systems. We see this more on south-facing doors without storm protection. The slab picks up heat all afternoon, and the hinge-side edge starts to drift. The result is a door that binds at the top in July and lets light through the gap at the bottom in January. Sometimes the fix is adjusting hinges and re-setting the threshold. Sometimes the slab has taken a permanent set and needs replacement. We’ll tell you which one it is before any work starts, and we’ll quote both options on paper side by side.
• Failed caming and seal degradation on decorative glass packages. Therma-Tru’s decorative doorlites, including the Maiden and Craftsman patterns, use caming that can lift from the glass surface after years of humidity cycling. The glass still functions, but the seal at the caming edge becomes a moisture entry point. We re-glaze these units with proper structural adhesive and ensure the decorative assembly is sealed before it goes back into the door.
• Impact-rated sidelites losing their gas fill in coastal neighborhoods. Homes from El Cid south to South End that went through the 2010s impact-glass retrofit wave are now seeing sidelite IG units that have lost their argon charge. The laminated impact glass is still intact, but the energy performance is gone. We replace the interior IG unit while preserving the impact-rated outer lite, which keeps the hurricane protection intact and restores the thermal break without replacing the entire sidelite frame.

Our Therma-Tru Energy-Efficient Windows Process

Every Therma-Tru job follows the same sequence, whether it’s a single fogged sidelite or a full entry system glass package. Dale Kessler grew up in Northwood Hills watching his father re-glaze storefronts along Dixie Highway, and the process hasn’t changed in principle since then. If it is not square, plumb, and sealed, it is not done.

1. 1
   Call and diagnosis. You call (561) 264-1279. A live person answers. We ask what you’re seeing - fog, draft, binding, water - and schedule a visit at a time that works for you.
2. 2
   On-site measurement and inspection. A background-checked, uniformed technician arrives, measures every opening twice, and checks the door slab for square, plumb, and level. We don’t skip this. A replacement glass unit ordered to a wrong measurement is the most common cause of failed Therma-Tru repairs we see from other installers.
3. 3
   Parts decision. We tell you what’s actually wrong and quote the options: OEM-equivalent insulated glass, aftermarket IG units with matched Low-E coatings, and full replacement sashes or slabs where the frame is past saving. You get both warranty layers in writing before we start.
4. 4
   The work. We pull the old unit, prep the opening, set the new glass with proper bedding and shimming, install new weatherstripping and sweeps as needed, and seal everything with backer rod and sealant rated for Florida humidity.
5. 5
   Testing and cleanup. We check the door operation through a full swing cycle, verify the reveal is even, and test the seal with a moisture meter where applicable. The work area is left broom-clean.
6. 6
   Warranty registration. Before the truck leaves, both manufacturer warranty layers are registered in writing with durations stated. Our Done Right Promise covers the workmanship. If something isn’t right, we come back and fix it. No argument.

What Therma-Tru Energy-Efficient Windows Costs in West Palm Beach

Pricing on Therma-Tru energy work breaks down by scope. Here’s what we typically see in West Palm Beach, from Northwood to Southland Park:

• Single sidelite IG unit replacement: $310 to $485, depending on size and Low-E spec.
• Fogged glass replacement on a Classic-Craft full-lite door: $420 to $640, including new glazing tape and sealant.
• Door-bottom sweep and weatherstripping replacement: $95 to $165, installed.

• Decorative doorlite re-glazing: $180 to $340, depending on pattern complexity.

What moves the price: the size of the glass unit, whether it’s Low-E or Low-E with argon fill, impact-rating requirements, and whether the door slab needs to be replaced or just re-set. Every quote is a fixed line-item price in writing before work begins, so you’ll never see a surprise change order.
