Therma-Tru Door Replacement in Fort Lauderdale: What to Know First

Therma-Tru door replacement in Fort Lauderdale typically runs $1,800 to $5,400 depending on the door line, glass package, and whether the frame needs rebuilding. As an independent Therma-Tru service provider, Juniper Windows Fort Lauderdale handles the full replacement: we pull the old slab and frame, set the new unit, and warranty the work for 365 days, parts and labor, in writing. You’ll get a written price before anything starts, so there’s no mystery number waiting at the end. If you own a Therma-Tru entry door that’s warped, rusted at the bottom rail, or letting daylight through the weatherstripping, this page covers what’s actually wrong and what replacement costs.

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

Therma-Tru makes a solid door, but Fort Lauderdale’s salt air, rain, and humidity find the weak points faster than a dry climate ever would. Here’s what we see most on replacement calls:

• Rusted bottom rail on Classic-Craft and Fiber-Classic slabs. Therma-Tru’s fiberglass skins hold up well, but the bottom sweep channel and internal wood blocking trap moisture. After a few wet seasons near the Intracoastal, the bottom rail swells and the door starts dragging on the threshold. By the time most homeowners call, the slab has split at the bottom corners. We replace the full unit rather than patching, because a patched rail re-splits within a year in this climate.
• Frame rot at the sill on older Smooth-Star installations. The Smooth-Star line was everywhere in Fort Lauderdale homes built in the mid-2000s. The slab itself resists rot, but the wood frame kit behind it doesn’t. Once the sill knee rots, the door sags, the deadbolt misses the strike plate, and the lock grinds. We rebuild the rough opening and set a new frame instead of shimming a rotten one.
• Warped slab from direct western sun exposure. Therma-Tru uses a composite core, but dark-painted doors on west-facing entries in neighborhoods like Victoria Park or Rio Vista can still move when they bake all afternoon. The door bows just enough that the top corner catches the frame. Sometimes it’s a hinge tune; more often, the slab has developed a permanent twist and the fix is replacement with a lighter-reflecting color or an insulated core upgrade.
• Failed weatherstripping and glass seal fog on the decorative glass lines. Therma-Tru’s decorative glass inserts (the Santiago, Verona, and Craftsman patterns) are double-glazed, but the seal between panes eventually lets go in the heat. Once the glass fogs from the inside, there’s no field repair. We source replacement insert packs or swap the entire slab if the style has been discontinued.
• Impact-rated door frame separation after a storm season. Therma-Tru makes impact-rated door systems, but we’ve replaced units where the frame pulled away from the rough opening because the original installer used standard anchors instead of the specified hurricane ties. If the door still locks but the frame flexes when you lean on it, the structure behind it is the problem, not the slab. We correct the anchoring when we set the new frame.

Our Therma-Tru Door Replacement Process

Here’s how a Therma-Tru replacement goes when you call us in Fort Lauderdale:

1. 1
   Schedule and walk the door. We book the visit and give you a live arrival time. On site, we check the slab, frame, hinges, and threshold, not just the obvious problem.
2. 2
   Diagnose the actual failure. Sean Mackey’s crew has pulled enough Therma-Tru units to know the difference between a bad slab and a bad frame. That diagnosis determines whether we’re replacing the door only or the door and frame together.
3. 3
   Lock the written price. You get a written line-item price before any work starts. No estimate that morphs into a surprise invoice, no change orders unless you change the scope yourself.
4. 4
   Set the new unit. We remove the old slab and frame, correct the rough opening if needed, and set the new Therma-Tru unit with the right anchoring and sealant for South Florida exposure.
5. 5
   Test everything. The door swings, the deadbolt throws, the weatherstripping seals, and the threshold drains. We send before-and-after photos through the Relay Visibility system.
6. 6
   The 365-Day Done Right Promise applies. If anything isn’t right within a year, we fix it. Parts and labor, in writing.

What Therma-Tru Door Replacement Costs in Fort Lauderdale

Here’s the honest range for the Therma-Tru jobs we quote in this market:

• Slab-only replacement (Smooth-Star or Classic-Craft, no frame work): $1,800 to $2,800. The existing frame has to be square and rot-free for this to work.
• Full unit replacement with new frame (standard fiberglass lines): $2,400 to $3,900. This is the most common scope we do.
• Impact-rated Therma-Tru system (door, frame, glass, anchoring): $3,800 to $5,400 and up, depending on glass package and size.

What moves the price: whether the frame is salvageable, the glass insert style, the paint finish, and whether the rough opening needs correction. Every quote is written and fixed before work starts. Call (754) 354-1396 for an exact number on your door.
