Key Takeaways

• Installed Therma-Tru door replacement in West Palm Beach generally lands between $850 and $1,900 depending on slab, frame, and hardware condition.
• West Palm Beach humidity and salt air shorten weatherstripping and threshold life faster than dryer climates, so we recommend inspecting seals every 12 months.
• We stock common Therma-Tru replacement parts and can order model-specific components, typically arriving in 3 to 5 business days.
• Every job includes a written price before work starts, shoe covers and drop cloths inside your home, and our 365-Day Done Right Promise.

Which Therma-Tru Models This Applies To

Therma-Tru builds three main door families that show up most often in West Palm Beach homes. The Classic-Craft line has a fiberglass skin with a realistic wood grain and takes standard compression weatherstripping. The Smooth-Star series is the painted, smooth-faced fiberglass door common in newer construction. The Pulse line has a polyurethane core and a slightly thicker edge profile, which means its weatherstripping and sweeps are not interchangeable with Classic-Craft parts. Check the hinge-side edge of the door slab for a Therma-Tru label or embossed part number. The label usually lists the series, the door size, and the glass package reference. We keep a caliper on every service call, because a door stamped 36×80 can still measure 35 3/4 inches wide on a hot afternoon, and that changes which replacement sweep and threshold kits will seat properly.

For most functional replacement parts like sweeps, corner pads, and threshold caps, a quality aftermarket equivalent matched to the correct series works fine and often ships faster than an OEM order. But for structural components like the door slab itself, the frame, or Therma-Tru’s Tru-Defense impact-rated glass, we recommend staying with genuine Therma-Tru product. The warranty matters on those pieces, and no generic substitute carries the same Miami-Dade or Florida Building Code testing paperwork. Lightwell Windows West Palm Beach is an independently owned and operated service provider and not affiliated with Therma-Tru; we’re simply a local crew that installs and services their doors.

Signs Your Therma-Tru Door Installation Is Failing

• The door drags or sticks at the bottom corner. In West Palm Beach, expansion from heat and humidity causes the slab to swell slightly, and a sweep or threshold cap that was fine in January drags by July. The fix is usually a new sweep with the correct clearance, not a planed door.
• Visible daylight around the edges. Compression weatherstripping crushes over time, especially on the lock side. Once the kerf insert loses its bounce, the door leaks conditioned air and lets bugs in. That’s a quick replacement, often done in under 30 minutes.
• The door no longer latches without lifting or pulling. This is usually a hinge sag from a loose top hinge or a worn strike plate. A door that needs a hip-check to close is telling you the alignment has drifted, and the cause should be fixed before the slab rubs the frame permanently.
• Water staining on the interior floor near the door. In West Palm Beach’s summer downpours, a worn threshold cap or failed corner pad lets driven rain track inside. Left alone, that water reaches the subfloor and starts a repair bill far bigger than a threshold replacement.
• The door feels loose in the frame when closed. If the slab shifts a quarter inch when you push on it, the weatherstripping has compressed or the adjustable threshold has dropped. This is the stage before the door starts rattling in wind and losing its seal entirely.

Replacement Cost & What’s Included

For a Therma-Tru door installation in West Palm Beach, here’s a realistic breakdown of what you’ll see on a written quote. Parts and labor are separated on every invoice, so you know exactly what you’re paying for before we start.

Price moves with the series, the size of the opening, the condition of the existing frame, and whether the home sits in a coastal zone requiring impact-rated product. What doesn’t move is our process: a background-checked, uniformed technician arrives with the written quote already prepared, reviews it with you before touching anything, and leaves you a photo of the clean site when the work is done. Every Therma-Tru door installation we complete carries the 365-Day Done Right Promise. If it’s not right, Lightwell makes it right.

DIY or Call Us?

A homeowner can safely handle a few Therma-Tru checks without calling us. Look at the sweep: if it’s brittle, cracked, or flattened, it’s worn out. Inspect the weatherstripping by closing the door on a dollar bill; if the bill slides out easily, the seal is gone. Those observations help you describe the problem accurately over the phone. Where DIY goes wrong is alignment and hinge work on a heavy fiberglass slab. A Therma-Tru door with a Tru-Defense glass package can weigh over 100 pounds, and resetting a door that heavy without the right shims and a second set of hands risks injury to you and damage to the frame. Keith Yamada has measured, flashed, and finished doors from every angle after years in the building trades, and he’ll tell you plainly: some jobs are worth paying a careful crew to do.
