Therma-Tru Impact Windows in West Palm Beach: What to Know First
We install, repair, and replace Therma-Tru impact-rated windows and doors across West Palm Beach as an independent Therma-Tru service provider, not a factory-authorized dealer. Most Therma-Tru impact glass repairs in West Palm Beach run between $240 and $1,800 depending on whether it’s a seal failure, a fogged sash, bent hinge hardware, or a full panel replacement, and most jobs finish in one visit. If you own a Therma-Tru entry door system or French door with impact-rated glass and you notice condensation between panes, a door that drags in August, or glass that no longer sits square in its frame, call (561) 264-1279 and we’ll sort it out.
This page is for West Palm Beach homeowners who already own Therma-Tru products and want straight answers about impact windows without a sales script behind them.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds a solid fiberglass door, but impact-rated glazing lives in a rough environment here. Salt air, afternoon thunderstorms, and summer humidity work on seals and hardware in ways a brochure never mentions. What we see across West Palm Beach, year after year:
- Seal failure on Fiber-Classic and Classic-Craft impact door lites. The insulated glass unit in these doors is sealed with a spacer that eventually lets Florida humidity in. The first sign is a faint haze at the glass edge that worsens into full condensation between panes. Once the seal goes, the insulating gas escapes and the lite loses its thermal performance. We replace the IGU and re-glaze the opening, matching the original glass package.
- Threshold and hinge sag on Therma-Tru Smooth-Star and Pulse impact systems. A fiberglass door panel is light for its size, but an impact-rated panel carries more glass and more structural load. In West Palm Beach, houses settle on sandy soil, and over a decade or two the rough opening moves a fraction of an inch. That’s enough to make a Therma-Tru door scrape the threshold in July, then close too easily in January. We reset the door, square the frame to the rough opening, and re-hang rather than shaving the threshold, which is only masking the problem.
- Fogged or failed glazing in Therma-Tru French door sidelites. The slim profiles on French door sidelites look right, but the seal area is narrow. We see more seal failures there than on the door panels themselves. The fix is a new dual-pane impact IGU, and we pressure-test the finished unit before sealing the trim.
- Stripped or corroded hinge screws on coastal-facing Therma-Tru doors. Houses within a mile of the Intracoastal get salt in places you would not expect. The zinc screws Therma-Tru ships from the factory hold up fine in Indiana but not forever on Flagler Drive. We replace with stainless hardware matching the original reveal, and we back the hinge mortises with epoxy when the fiberglass has wallowed out.
- Impact-rated storm doors with fractured or crazed glazing. We regularly see Therma-Tru storm door glass with small impact cracks from wind-blown debris, tree limbs, or lawn equipment. Owners sometimes assume they need a whole new door. In most cases the sash reglazes cleanly with a new impact-rated panel at a third of replacement cost.
Our Therma-Tru Impact Windows Process
When you call TruePane Windows & Doors about a Therma-Tru issue in West Palm Beach, here’s the actual sequence of events, no mystery and no upselling between steps:
- 1
Call (561) 264-1279. A person answers. You describe what you’re seeing. We ask about the age of the unit, whether it’s an entry door or side lite, and what the glass looks like today.
- 2
On-site inspection. We measure the rough opening, check the frame for square and plumb, and identify the exact Therma-Tru series stamped on the door edge or glass etching. We do not quote without looking at the opening, because the opening drives the repair half of the time.
- 3
Parts decision on paper. We give you side-by-side prices for an OEM Therma-Tru glazing unit and a quality aftermarket equivalent where one is available. Both options get the same warranty registration treatment. You choose based on cost and lead time, not because we pushed you.
- 4
Repair or replacement. For a reglaze, we remove the old IGU, prep the opening, set the new unit, and re-trim. For a door reset, we pull the panel, correct the hinge-side geometry, and re-hang.
- 5
Pressure and water testing. Before we call the job finished, we run a water test on the exterior and a pressure check on the seal. If it leaks, we redo it before we leave.
- 6
Warranty registration before we leave the driveway. The Keystone Standard means both manufacturer warranty layers get registered in writing, with durations stated. No discovered-later loopholes.
What Therma-Tru Impact Windows Costs in West Palm Beach
Here are honest numbers for the Therma-Tru work we do in West Palm Beach. These are line-item ranges, not firm quotes, because the price depends on the condition of the rough opening, the series of door or window involved, and whether the glazing unit is a stock size or a custom cut.
| Therma-Tru Job | Typical Cost Range |
|---|---|
| Fogged IGU replacement (impact-rated, single lite) | $240 - $480 |
| Impact door lite reglaze with new seal | $380 - $750 |
| French door sidelite glazing replacement | $300 - $600 per side |
| Threshold reset and hinge re-alignment (door sag fix) | $450 - $900 |
| Full impact-rated Therma-Tru door replacement (installed) | $1,600 - $3,500 |
| Storm door reglaze with impact-rated panel | $280 - $540 |
What moves the price: custom glass sizes, interior trim that has to be milled to match existing, and the condition of the rough opening once we expose it. If it is square and solid, the job is straightforward. If it is not square, plumb, and sealed, the job is not done until we correct it, and that labor shows up on the written estimate before work starts, never as a surprise line item. Call (561) 264-1279 for a free estimate with numbers on paper.
Why West Palm Beach Homeowners Call TruePane Windows & Doors for Therma-Tru Work
We are not a franchise. Dale Kessler grew up in Northwood Hills and spent enough summers watching his father re-glaze storefront windows along Dixie Highway to know he wanted to work with glass for a living. That means when a Therma-Tru impact door in West Palm Beach fails, our technicians know the difference between a seal failure and a structural problem, and they have been trained to fix the first one without creating the second.
Every Therma-Tru job we do carries the Done Right Promise. If it is not done right, we make it right. No paperwork, no arguing, no fine print that covers neither. We also stand behind the workmanship for a full ninety days because a warranty is only as good as the person who answers the phone when you call. And we answer. A live person, 24 hours a day, 7 days a week.
If the repair does not make sense, we also install impact-rated windows and doors from PGT, CGI, CWS, and ES Windows. That matters if your Therma-Tru unit is past practical repair or if you want a multi-brand quote before you spend. We are authorized installers for more than a dozen manufacturers, and we put the options side by side on paper so you can see what you are buying.
FAQs
No, not when the work is done correctly. A warranty does not void simply because an independent contractor does the repair. What voids a Therma-Tru warranty is an improper installation, an unregistered glazing unit, or a structural modification made without correcting the original frame problem. That is precisely why we register both manufacturer warranty layers in writing before the truck leaves the driveway and why we list the warranty durations on the work order. Call (561) 264-1279 and we will walk you through what your specific Therma-Tru model carries.
In West Palm Beach, reglazing a single impact lite runs $240 to $480, while a full Therma-Tru impact door replacement runs $1,600 to $3,500 installed. As long as the fiberglass panel and the rough opening are structurally sound, reglazing is the better financial decision. We will tell you if it is not. Free estimates at (561) 264-1279.
In most West Palm Beach homes, a single lite reglaze or glazing replacement finishes in under two hours on site. The parts lead time varies by series and glass package, typically three to ten business days. We schedule the work once the glass is in hand and the warranty is registered, so you are not waiting through multiple visits.
That is the classic symptom of a rough opening that has moved with the seasonal water table and sandy soil shifting. The fiberglass panel stays true, but the frame around it does not. In West Palm Beach, we reset the hinge side, re-shim the rough opening, and re-hang the panel so it closes properly all twelve months. Shimming the threshold or sanding the panel edge is a temporary fix that returns the following summer. Call (561) 264-1279 and we will measure the opening.
No. We are an independent Therma-Tru service provider, which means we repair and replace Therma-Tru products without being tied to factory pricing or sales quotas. That independence matters when an aftermarket glazing unit is the smarter buy than an OEM one, and we show you both options on paper. What we do carry is manufacturer authorization for more than a dozen other lines, including PGT and CGI, so if a Therma-Tru replacement is not the right long-term answer, we have alternatives to price side by side.
