Therma-Tru Impact Windows in West Palm Beach: What to Know First
Therma-Tru impact windows in West Palm Beach can be repaired or replaced by our crew, usually within 5 to 7 business days of your call, depending on parts availability. We’re an independent Therma-Tru service provider, which means we fix what’s failing instead of pushing a full replacement unless the frame truly warrants it. Most Therma-Tru impact window work in this area lands between $350 and $1,800 per opening, and you’ll get a written line-item quote before anything gets ordered.
This page is for West Palm Beach homeowners who already own Therma-Tru doors or windows and need straight answers about repair, replacement, parts, and what things actually cost here, where salt air and hurricane season both do a number on hardware. If that’s you, call (561) 660-9539 and a live person picks up, day or night.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds a solid product, but no window survives West Palm Beach’s combination of salt, humidity, and afternoon thunderstorms without showing wear. Here’s what we see most often on Therma-Tru impact units in this market, and what we do about it:
- Weatherstripping compression on Classic-Craft and Smooth-Star lines. The foam bulb seals on these series flatten over time, especially on west-facing exposures where the afternoon sun cooks the door or window for hours. You’ll feel a draft or see daylight at the corner. We replace the weatherstripping with a denser compression-rated material that holds its shape in Florida heat, rather than the factory original that tends to re-flatten within two seasons.
- Impact glass seal failure on Therma-Tru slim-profile units. We get calls from neighborhoods like Northwood Hills and El Cid where Therma-Tru impact windows are now 8 to 12 years old and the insulating gas between panes has leaked. The telltale sign is fogging that comes and goes with humidity, not a crack. The fix is glass-pack replacement, not a full window swap, and it keeps your original frame and trim intact while restoring the impact rating.
- Sagging or misaligned Therma-Tru hinged patio doors. The Benchmark series, which Therma-Tru positions for patio and entry applications, carries a lot of glass weight. Over time the hinge side settles, especially on concrete slabs that shift during our wet-dry seasonal cycles, and the door starts dragging or won’t seal evenly. We re-shim the frame, reset the hinges, and re-time the multi-point locking hardware so the door closes square again.
- Corroded multi-point lock mechanisms on impact-rated door units. This is the one owners don’t see coming. The internal gearbox and shoot bolts on Therma-Tru entry systems sit inside the door stile, where salt air still finds a way. When the thumb-turn gets stiff or won’t engage the top shoot bolt, that’s corrosion in the gearbox, not a dirty track. We replace the gearbox and shoot bolts with marine-grade aftermarket parts that hold up better within a mile of the Intracoastal.
- Deteriorated sill caps and threshold gaskets on Fiber-Classic doors. West Palm Beach’s rainy season, all six months of it, puts standing water on door thresholds constantly. The factory sill cap on older Fiber-Classic units cracks along the screw channels, and then water wicks into the subfloor. We pull the old sill, inspect the framing beneath, and install a reinforced threshold with a full-length gasket that actually drains instead of trapping moisture.
Our Therma-Tru Impact Windows Process
Here’s how a Therma-Tru job goes when you call Winslow Windows & Doors:
- 1
You call (561) 660-9539. A live person answers, 24/7. No answering service, no call center. You’ll tell us what’s happening: fogged glass, a dragging door, a lock that won’t throw, a draft you can’t trace.
- 2
We come out and diagnose. A background-checked technician in uniform shows up at the scheduled time. We inspect the unit, identify the specific Therma-Tru series and hardware, and figure out whether the failure is in the glass pack, the frame, the weatherstripping, or the hardware.
- 3
We give you a written line-item quote on the spot. No vague “we’ll get back to you.” You’ll see exactly what parts cost, what labor costs, and what’s optional. Ed’s name is on the quote, and the price doesn’t change once work starts.
- 4
We source the right parts. For warranty-sensitive situations, we use genuine Therma-Tru components. For corrosion and weatherseal failures, we’ll often recommend a superior aftermarket part and explain why it’ll outlast the original in this climate. The choice is always yours.
- 5
We do the work and test it. Whatever we repair gets function-tested while you watch: the lock throws, the glass is clear, the door closes square, the draft test comes back clean. We don’t leave until it’s right.
- 6
The Done Right Promise kicks in. If it’s not done right, we make it right. That’s a hundred years of our word. Ed Winslow grew up in Northwood Hills, and his name’s on every truck and every invoice.

Why West Palm Beach Homeowners Call Winslow Windows & Doors for Therma-Tru Work

FAQs
No. As an independent Therma-Tru service provider, we follow manufacturer-spec procedures and use genuine Therma-Tru parts where your warranty is still active. We’ll tell you before we touch anything whether the repair falls inside or outside the original coverage. Call (561) 660-9539 and we’ll check your unit.
Most common parts (weatherstripping, lock gearboxes, sill caps) are in hand within 3 to 5 business days through our supply chain. Glass packs run longer, typically 7 to 10 business days, because they’re cut and tempered to your exact frame dimensions. We’ll pin the timeline on your quote before you commit.
Typically, repair. If the frame is square, the sash moves freely, and the fogging is the only symptom, a glass-pack replacement restores the impact rating and insulation for about half the cost of a full window. Replacement only makes sense when the frame is rotted, racked, or the hardware is beyond economical repair. We’ll show you the numbers either way.
Both. We work on Therma-Tru Classic-Craft, Smooth-Star, Fiber-Classic, and Benchmark entry and patio doors, from threshold replacement and hinge resets to full impact-rated door installs. West Palm Beach salt air hits doors harder than windows, so if your Therma-Tru door is dragging or corroding, don’t wait until it won’t close at all.
No. You get a written line-item quote before we order parts, and that number is the number you pay. If we open up the wall or the frame and find something genuinely unexpected, we stop, show you, and get your sign-off before spending another dollar. My name’s on the truck. That means something. Call (561) 660-9539 for your free estimate.
