Therma-Tru Door Installation Nationwide

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

Therma-Tru door installation in West Palm Beach typically runs $850 to $1,900 installed, depending on whether it’s a slab swap or a full frame-out with new weatherstripping and threshold work. We stock Therma-Tru-compatible door installation hardware on our trucks, and in most cases we can complete the replacement the same day we diagnose it. Most owners don’t set out looking for door installation help. They notice the door dragging against the sill, a deadbolt that won’t fully throw, or daylight sneaking in around the frame after a hard South Florida rain, and they trace it back to sagging hinges, a rotted corner, or a warped slab that has finally stopped forgiving the humidity.

We’re Meridian Windows and Doors West Palm Beach, an independent service provider. We’re not affiliated with Therma-Tru, but we install their doors because the product holds up when it’s hung correctly. Elliot Vance has been putting doors in across West Palm Beach for over a decade, and the crew has learned one thing: a Therma-Tru door is only as good as the opening it sits in. Measure it right the first time and the install explains itself.

Which Therma-Tru Models This Applies To

Therma-Tru builds its door systems around two main families: the Classic-Craft and Fiber-Classic lines, with Smooth-Star as the budget-conscious option. The good news is that the installation fundamentals are the same across all three. What changes is the slab thickness, the hinge prep, and the weatherstrip profile. Classic-Craft slabs are typically 1-3/4 inches thick and come factory-drilled for standard 4-1/2-inch hinges. Smooth-Star and Fiber-Classic run the same thickness, but older units from 2005 to 2012 occasionally have non-standard hinge spacing that will fight you if you assume otherwise.

Here’s the compatibility gotcha we see over and over in West Palm Beach: the frame matters more than the slab. A Therma-Tru slab dropped into an old wood jamb that has been soaking up Florida humidity since the Clinton administration will never seal right, no matter how well the hinges are shimmed. Before we quote a door installation, we check the jamb with a 6-foot level on both sides and the head. If the frame is racked more than 1/8 inch, you’re better off replacing the full system rather than paying labor twice. For OEM versus aftermarket, we default to genuine Therma-Tru weatherstripping and sills, because the profiles are proprietary. Hinges and threshold screws are a different story. Those are commodity hardware, and spec-grade aftermarket parts do the same job for less money. We’ll tell you which parts deserve the Therma-Tru name and which don’t.

Signs Your Therma-Tru Door Installation Is Failing

• Door drags or sticks at the top latch-side corner. The slab has settled because the top hinge screws have lost their bite in the jamb. In West Palm Beach’s humidity, wood jambs soften over time, and a door that scraped once a month now scrapes every day. The fix is longer screws that anchor into the stud, but by the time you notice it, the weatherstrip has usually been chewed up too.
• Deadbolt won’t throw without lifting the handle. The strike plate is now out of alignment with the latch. This is rarely a lock problem. It’s a sag problem, and shimming the bottom hinge is the usual repair. Ignoring it wears the latch mechanism until the lock itself gives out, which turns a $200 call into a $500 one.
• Visible daylight around the perimeter or cold air at the threshold. The weatherstripping has compressed beyond recovery, or the sill has settled. Therma-Tru’s compression weatherstrip works until it doesn’t, and once it’s flat, no amount of WD-40 brings it back. Replacement is a 20-minute job with the right profile in hand.
• Water staining at the bottom corners of interior drywall. The threshold pan or the jamb-to-sill seal has failed. In South Florida, wind-driven rain finds every gap, and a failed sill pan shows up as bubbling paint or soft drywall before you ever see standing water. This is the one symptom that demands immediate attention before rot spreads into the subfloor.
• Door swings open or closed on its own. The jamb is out of plumb, or the hinges have been adjusted enough times that the leaves are sprung. A door that won’t stay where you leave it is more than an annoyance. It’s a sign the opening has moved, and no amount of doorstop shuffling will fix the underlying rack.

Replacement Cost & What’s Included

Let’s talk straight numbers for West Palm Beach. A basic slab swap on an existing sound frame runs $850 to $1,200 installed, including the new slab, hinge hardware, and weatherstripping. A full frame-out with new jambs, threshold, exterior trim, and interior casing typically lands between $1,400 and $1,900. If you’re adding a decorative glass insert or upgrading to a premium finish, the material cost rises, but labor stays predictable. We write the price on paper before any work starts, and that number does not move at the door.

What’s included: removal and disposal of the old door, leveling and shimming of the new slab, fresh hinge screws anchored into framing, new Therma-Tru weatherstrip and threshold sweep, and a clean work area when we leave. Every installation carries our 365-Day Done Right Promise in writing. If the work fails within that year, we come back at no charge. No fine print about labor exclusions. The price we quote is the price you pay.

DIY or Call Us?

There are a few things an owner can safely check before picking up the phone. Yes, you can tighten face-plate screws on the hinges. Yes, you can run a strip of masking tape along the frame to see where the weatherstrip is making contact and where it has gone flat. No, you should not try to re-hang a 70-pound Therma-Tru slab by yourself. And you should definitely not attempt to plane down a fiberglass door edge. Fiberglass doesn’t plane like wood. It shreds, and once you break the factory edge seal, moisture gets inside the composite and the slab starts to swell. We have replaced doors for homeowners who tried to save a hundred dollars with a belt sander and ended up needing a $1,200 door instead.

If you’re not sure whether the frame is still sound, call us at (728) 728-9381. We’ll tell you over the phone whether it sounds like a hinge adjustment or a full replacement. Estimates are free, and you’ll get the number before we touch a screw.
