This page is for homeowners who bought a house with Therma-Tru windows, had them installed years ago, or are weighing whether to replace individual units versus the full frame. Winslow Windows & Doors is an independent Therma-Tru service provider, not a factory-authorized dealer. That matters because we’re not tied to a corporate script when we tell you what’s actually wrong with the window.

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

Therma-Tru built its name on doors, and its window lines share a lot of that door DNA. In West Palm Beach, we see the same failure patterns repeat across neighborhoods from Northwood Hills to South End. Here’s what actually happens and what we do about it.

• Seal failure in the Classic-Craft and SlimLine series. The insulated glass units in these lines start fogging between panes after seven to ten years of South Florida humidity. That haze isn’t condensation you can wipe off; it’s a broken seal letting moisture into the air space. We replace the full sash or the glass unit, not the whole frame, which saves you hundreds per window.
• Warped sashes on Therma-Tru’s vinyl replacement lines. Direct sun on west-facing walls in West Palm Beach can push vinyl sashes out of square, especially on windows installed before 2015. The telltale sign is a window that locks fine in January but fights you in August. We shim, realign, or replace the sash depending on how much the frame moved.
• Roller and balance wear in sliding and double-hung units. Therma-Tru’s sliding windows use a nylon roller system that grinds down over thousands of open-close cycles. You’ll hear a gritty sound or feel the sash drag. If we catch it early, it’s a parts swap. If the track is scored, it’s time for a new window.
• Frame rot at the bottom corners of wood-clad units. Therma-Tru’s wood-clad windows hold up well, but West Palm Beach’s wet season punishes any wood that stays damp. We see rot start at the bottom corners where irrigation spray hits the frame. A full frame replacement with a composite or vinyl unit fixes it permanently instead of patching it every two years.
• Hardware fatigue on casement operators. The crank mechanisms on older Therma-Tru casements strip internally after years of salt air exposure. The handle turns but the window doesn’t move. Aftermarket operators from established suppliers fit correctly and outlast the originals; we stock several options and don’t make you wait for factory backorder.

Our Therma-Tru Window Replacement Process

When we replace Therma-Tru windows in West Palm Beach, the process is the same every time, and it doesn’t involve surprises.

1. 1
   The call. You reach a person, not a recording, at (561) 660-9539. We schedule a time that works for you. No trip charge if you’re inside the county.
2. 2
   The inspection. We measure, photograph, and test every window you’re concerned about. You get a written line-item estimate with the exact work and exact materials before you commit to anything.
3. 3
   The parts decision. If OEM Therma-Tru replacement parts make sense for the age and condition of the window, we use them. If an aftermarket component from a solid supplier will do the same job for less without voiding your warranty path, we tell you and you decide.
4. 4
   The install. Background-checked techs in uniform arrive, protect the work area, and install to manufacturer specs. Existing openings get cleaned, squared, and resealed before the new unit goes in.
5. 5
   The test. We operate each window through its full range, check the seal with a smoke pencil, and confirm locks and hardware. You walk the job with us before we pack up.
6. 6
   The paperwork. You get your receipt, warranty information, and our Done Right Promise in writing. If it’s not done right, Ed Winslow comes back and makes it right.

What Therma-Tru Window Replacement Costs in West Palm Beach

Here’s the straight answer on pricing. Therma-Tru glass unit replacement for a fogged or failed seal runs $250 to $600 per window. Insert window replacement into an existing sound frame runs $500 to $1,100 per opening. Full frame replacement, where we pull the entire old unit and rebuild the rough opening, runs $900 to $2,400 per window depending on size, glass package, and whether we’re adding impact glass. Three things move the price most: frame condition, whether the opening is standard or custom-sized, and whether you want energy-efficient glass upgrades. Every estimate is free, written, and line-itemed. Call (561) 660-9539 and we’ll give you exact numbers for your house.

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

Ed Winslow grew up in Northwood Hills, where the houses have character and the windows definitely show their age. He went through the building construction program at Palm Beach State College and spent summers helping his father-in-law seal up drafty doors across the county. That’s the guy whose name is on the truck. We’ve been installing and repairing windows in West Palm Beach since 2011, and our techs know Therma-Tru’s quirks the way a mechanic knows a specific car’s engine. But we also install PGT, CGI, CWS, and ES Windows, so if your best move is leaving Therma-Tru behind, we’ll tell you honestly instead of forcing a brand that doesn’t fit. The Done Right Promise covers every job. A live person answers every call, 24/7. Upfront pricing means no surprises on the invoice. That’s the whole pitch.
