Therma-Tru Impact Windows in Palm Beach: What to Know First
If you own Therma-Tru doors or windows in Palm Beach and need impact-rated protection, we install and service Therma-Tru impact windows as an independent Therma-Tru service provider. Most Therma-Tru impact window replacements in Palm Beach take one to two days once materials are in hand, and we quote every job upfront with no change orders. You’ll get a written line-item estimate before any work starts, and calls to (561) 831-7863 are answered by a real person, day or night.
This page is for Palm Beach homeowners who already trust the Therma-Tru name and want impact-rated performance without the national-chain runaround. Ed Winslow’s name is on the door here, and his crew has worked on Therma-Tru products across Palm Beach for years, including along El Brillo Way where finishes and impact ratings aren’t negotiable.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru makes a solid door, but Palm Beach humidity, salt air, and hurricane cycles expose weak points that don’t show up on a manufacturer spec sheet. Here’s what we see in the field and what we do about it.
- Therma-Tru Smooth-Star frames losing corner seal adhesion. The Smooth-Star line uses a fiberglass composite that holds up well, but the corner joints rely on adhesive that Palm Beach’s salt-and-moisture combination gradually eats. You’ll see hairline gaps at the bottom corners first, then drafts and water intrusion during a driving rain. We disassemble, re-seal with a marine-grade adhesive that outlasts the original, and re-flash the opening properly.
- Therma-Tru Classic-Craft warping at the threshold on east-facing exposures. Classic-Craft doors have a real wood edge band around the panel. Morning sun off the Atlantic plus afternoon heat can warp that edge band, which throws the door out of square and breaks the impact seal. When this happens on repeated Palm Beach east-side jobs, the fix is almost always a new impact-rated slab, not a band-aid patch. We measure, order, and hang it square against the existing frame.
- Impact glass seal failure in Therma-Tru Benchmark patio doors. The Benchmark line runs heavy sliding door surfaces, and we see failed window seals show up as fogging between the panes within six to eight years near the ocean. Salt gets into the seal geometry. Once the insulated glass unit loses its gas fill, it can’t hold its impact rating properly. We replace the IG unit with an impact-rated glass package that matches the existing frame, which costs far less than a new door.
- Weatherstripping compression set on Therma-Tru Pulse doors. The Pulse line uses a compression-style weatherstrip that works well for the first few seasons, but Palm Beach heat cycles flatten it. You’ll feel dead air loss around the latching stile. We swap in a high-recovery EPDM weatherstrip and re-set the latch for a tight seal, which is a quick job most owners don’t need a full door replacement for.
- Hardware pull-out on Therma-Tru fiberglass doors with original hinges. Fiberglass panels hold screws differently than wood or steel. Original hinges can wallow out their screw holes over a decade of use, especially on heavyweight doors. We drill, fill with a structural epoxy, and re-set with longer fasteners, or move up a hinge size if the door is carrying impact glass weight.
Our Therma-Tru Impact Windows Process
Here’s what a Therma-Tru impact window job looks like when you call Winslow Windows & Doors.
- 1
Call and talk to a person. You reach a live human at (561) 831-7863. We ask about the product, the symptoms, and the exposure. No ticket number, no callback queue.
- 2
On-site inspection and measurement. A uniformed, background-checked tech shows up at the scheduled time, measures the opening down to the sixteenth, checks the frame condition, and notes the existing Therma-Tru model if visible.
- 3
Parts decision: OEM vs. quality aftermarket. Some Therma-Tru components are worth sourcing direct from the manufacturer, especially warranty-covered hardware or proprietary seals. For glass packages and weatherstripping, we often recommend a performance aftermarket part that equals or beats the original spec at a lower price. We lay out the trade-off in plain English and let you choose.
- 4
Installation and flash. We set the new impact window or door into the opening using code-compliant flashing for Palm Beach wind zones, shim it square, and seal every penetration. This is where most leak-related repeat visits come from, so we take our time here.
- 5
Test and verify. We cycle the unit, check both latches, verify drain holes are clear, and spray-test the exterior where a hose and pressure make sense. If it doesn’t pass, it’s not done.
- 6
Walkthrough and paperwork. You get a written summary of what was done, what was used, and where you stand on warranty. Your 36500-Day Done Right Promise starts the day we leave, not the day you chase us down.
What Therma-Tru Impact Windows Costs in Palm Beach
Therma-Tru impact window pricing in Palm Beach runs wider than most people expect because the product line spans fiberglass entry units to full sliding patio packages. Here are honest ranges we quote from Palm Beach jobs.
- Impact-rated window replacement (per opening): $1,100 to $2,800 installed, depending on size, frame condition, and glass package
- Therma-Tru impact entry door (fiberglass, single): $2,400 to $5,500 installed with hardware and re-flashing
- Therma-Tru Benchmark impact sliding door (glass package replacement): $1,800 to $4,200 for the IG unit alone; full door replacement runs $4,500 to $9,000
- Weatherstripping, threshold, and seal rebuild on an existing Therma-Tru door: $180 to $650 depending on scope and part sourcing
What moves the price is the opening size, whether the frame is salvageable, and whether you’re in a high-wind zone that requires a heavier glass spec. We quote the same number before work that we charge after. Call (561) 831-7863 to schedule your free estimate, and we’ll walk the property with you.

FAQs
Warranty terms vary by product and model year, but we sequence every repair to protect what’s still covered. We’ll tell you before touching anything which components are warranty-eligible and which aren’t, so you can decide whether to pursue a manufacturer claim or pay out of pocket. Call (561) 831-7863 and we’ll walk through it with your specific Therma-Tru product.
A well-installed Therma-Tru impact window in Palm Beach conditions typically lasts 15 to 20 years before seals or hardware need meaningful work, with frames often outlasting the glass package. Coastal homes closer to the water lose glass seals sooner. We inspect glass integrity on every quote, so you know exactly where your windows sit in that lifespan.
In most cases, yes. We can source matching OEM hardware for current Therma-Tru lines, and for discontinued runs we match finish and size with quality aftermarket replacements that read identically from a few feet away. If exact match matters to you, tell us during the estimate and we’ll price it accordingly.
Replace when the frame is rotted, the glass seal is failed and the unit is over 12 years old, or the opening is so far out of square that shimming can’t bring it true. Repair when the problem is weatherstripping, hardware, a minor seal gap, or a single failing latch. Most Palm Beach homes we see need a mix of both, and we’ll tell you which is which without steering you to the more expensive option.
Once we have measurements and materials, most Palm Beach replacements are installed in one to two days. Custom orders from Therma-Tru or aftermarket suppliers add lead time, and we give you a straight timeline at the estimate, not after you’ve signed. Call (561) 831-7863 for a free estimate and we’ll give you dates, not guesses.
