Therma-Tru Door Installation: The West Palm Beach Owner’s Guide

We install Therma-Tru door slabs, frames, weatherstripping, sweeps, hinges, and threshold components throughout West Palm Beach, and most complete door installations run between $450 and $1,800 depending on whether we’re replacing a single component or an entire prehung unit. If your Therma-Tru door binds in July humidity or lets daylight through the jamb, we can typically diagnose it in one visit, and the most common parts live on our trucks. What usually brings West Palm Beach homeowners to this page is a door that worked fine for fifteen years and then started sticking, leaking, or refusing to latch, and the culprit is almost never as dramatic as a full door replacement.

Which Therma-Tru Models This Applies To

Therma-Tru built its reputation on fiberglass entry doors, and the compatibility details matter more here than with wood or steel slabs. Therma-Tru’s lineup splits into a few recognizable families: the Classic-Craft series, the Smooth-Star series, the Fiber-Classic series, and the Pulse series with its integrated locking system. Each uses proprietary corner joinery and jamb depths that are not interchangeable with generic big-box slabs. The most common compatibility gotcha we see in West Palm Beach is an owner who picked up a 4-9/16-inch jamb kit for a Florida home with 2×6 exterior walls and thicker stucco buildup. Those walls need a 6-9/16-inch jamb, and forcing the narrow kit leaves the casing proud of the interior drywall by half an inch. Identifying your model is straightforward: open the door and look at the hinge-side edge of the slab near the bottom. Therma-Tru stamps or labels the series name there on every door made in the last twenty years. If the label’s gone, we measure the slab thickness, hinge spacing, and bore pattern and match it to the correct series. OEM parts are our default recommendation for anything load-bearing like hinges, jambs, astragals, and multipoint lock mechanisms, because Therma-Tru tolerances are tight and the warranty stays intact when OEM goes in. For weatherstripping, sweeps, and corner seals, we stock quality aftermarket equivalents that match or outlast the originals in South Florida heat while costing 30 to 40 percent less.

Signs Your Therma-Tru Door Installation Is Failing

• The door sticks or binds at the top of the latch side in summer. West Palm Beach humidity swells wood sub-frames and shifts settling slabs. A Therma-Tru door that closes cleanly in January but drags in August usually has a jamb or threshold problem, not a slab problem.
• Daylight or drafts are visible along the bottom corners. Therma-Tru’s compression-style sweeps and corner seals flatten over time. Once the rubber loses its crown, you’re paying to air-condition the front porch.
• The door swings open or closed on its own. That means the hinges have worn or the jamb is out of plumb. Floating doors chew through weatherstripping and latches faster than anything else on the threshold.
• The handle feels loose or turns without retracting the latch. Therma-Tru’s hardware preps are standard 2-3/8-inch backset, but their multipoint locks on the Pulse series have small internal linkages that wear and fall out of sync. Aftermarket big-box hardware often doesn’t mate to the multipoint rail.
• You hear wind whistling through the astragal on a double door. Double Therma-Tru units depend on a clean, aligned astragal seal. Once it’s warped or torn, the gap lets noise, dust, and rain through and the inactive leaf starts rattling.

Replacement Cost & What’s Included

A Therma-Tru weatherstripping and sweep replacement in West Palm Beach typically runs $180 to $320, installed. Replacing hinges plus threshold lands between $280 and $650. A full prehung Therma-Tru unit with new slab, frame, installation and haul-away starts around $1,200 and can reach $2,800 for larger double doors with sidelites. What drives the range here in West Palm Beach is wall thickness, trim condition, whether we’re reusing existing hardware, and how much rot or settling we uncover once the old frame comes out. Every quote we write separates parts and labor line by line, and the price we give you is the price on the final bill, no change orders for surprises we should have caught during the measure. The workmanship is covered by our Done Right Promise, and we register the component warranty in writing before the truck leaves your driveway.

DIY or Call Us?

You can safely check a few things yourself: look for a visible Therma-Tru label on the hinge edge, check whether daylight passes under the sweep, and listen for whether the latch clicks fully into the strike plate. Those observations help us diagnose faster when you call. What you should not do is pull a prehung jamb out of a stucco opening without understanding how the threshold anchors tie to the slab, or try to adjust a Therma-Tru multipoint lock without the alignment jig. We’ve rebuilt a handful of West Palm Beach doorways where a well-meaning homeowner took the trim off, shimmed the jamb “just enough,” and ended up with a slab that never sealed again. Hinge routing, threshold bedding, and flashing against Florida wind-driven rain are not forgiving of guesswork. If you have any doubt, call us at (561) 264-1279 and we’ll tell you honestly whether it’s a simple fix or a full rehang.
