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

If you’re looking for Therma-Tru door installation in Palm Beach, here’s the straight answer: we install Therma-Tru entry doors, replacement door slabs, and all associated hardware, with most complete door replacements in this market running $1,800 to $4,900 installed depending on the door line, glass package, and what we find when we pull the old frame. A slab-only install on an existing frame lands closer to $900 to $1,600. Most owners discover they need us when the door starts dragging on the threshold, the corners of the frame have gone soft from humidity, or the deadbolt no longer lines up with the strike plate, and we can usually get to a Palm Beach door job within a few days of the first call.

Call (561) 831-7863 and Ed or one of our team will pick up. No call center, no ticket number. You’ll tell us what the door’s doing, we’ll tell you what it likely needs, and we’ll schedule a free on-site estimate from there.

Which Therma-Tru Models This Applies To

Therma-Tru makes a lot of door lines, and the good news is that replacement parts and hardware are broadly standardized across their catalog. We regularly work with the Classic-Craft, Fiber-Classic, Smooth-Star, and Pulse series, whether that’s an 8-foot entry door on a Palm Beach estate or a standard 6-foot-8 front door on a 1950s ranch.

The compatibility gotcha most people miss: Therma-Tru doors use a proprietary fiberglass composite edge system that is not drilled like a wood door. If you take a stock lockset boring jig to a Therma-Tru slab without the right spade bits and edge prep knowledge, you’ll delaminate the skin or crack the foam core. That’s an expensive mistake. The other thing to know is that Therma-Tru hinges are set to a 4-5/8-inch backset pattern that matches their pre-hung frames, and if someone swapped in generic hinges years ago, you’ll see lateral door sag that looks like a frame failure but is actually just mismatched hardware. We stock the correct hinge pattern and lockset adapters on our trucks.

On OEM versus aftermarket: for weatherstripping, sweeps, and hinge shims, quality aftermarket equivalents work fine and save real money. For door slabs, frames, and glass packages, we prefer OEM Therma-Tru components so the thermal expansion coefficients and seal geometry match. Mixing brands on a Florida entry door is how you get a door that binds in July and leaks in August.

Signs Your Therma-Tru Door Installation Is Failing

• The door drags or binds at the threshold. In Palm Beach, the most common cause is frame settlement combined with seasonal humidity swelling of the composite slab edge. It usually starts as a light rub and becomes a full drag by midsummer. A shim adjustment at the hinges or threshold replacement typically corrects it, but if the frame corner has shifted from rotted subfloor, the repair becomes a pull-and-reset job.
• The deadbolt misses the strike plate. This is the one we get calls about at 11 p.m., and for good reason: a door that won’t lock is a door that isn’t doing its job. It usually means the frame has warped or the slab has dropped. Quick fix some of the time; frame replacement more often than we’d like.
• Water stains or soft spots at the bottom corners of the frame. Therma-Tru’s composite frames resist rot, but the surrounding wall sheathing and subfloor don’t always survive years of blowing rain and sea air. If you press a screwdriver into the corner and it sinks, the door needs to come out, the opening needs repair, and the door gets reinstalled with proper flashing.
• You can see daylight around the side jambs. Worn weatherstripping is the simple answer. A warped slab or damaged frame is the expensive one. Either way, a door with visible gaps is pumping conditioned air into the Palm Beach humidity, and your AC bill shows it.
• The door feels heavier than it used to. Therma-Tru doors with raised panels and glass inserts are heavy to begin with. When the hinge alignment drifts, that weight shifts onto the lower hinge and the frame. You’ll feel it in the shoulder when you open it. Ignoring it turns a hinge repair into a frame replacement.

Replacement Cost & What’s Included

Here’s a realistic breakdown for Palm Beach, where labor rates reflect the cost of doing business in this market and material prices reflect current Therma-Tru distributor pricing:

• Slab replacement on existing frame: $900 to $1,600 installed (Therma-Tru Fiber-Classic or Smooth-Star slab, hinge and lockset prep, weatherstripping, threshold check)
• Full pre-hung entry door, mid-range: $2,200 to $3,600 installed (Classic-Craft oak or mahogany finish, standard glass, frame, trim, flashing, hardware mounting)
• Full pre-hung entry door, premium: $3,500 to $4,900 installed (Classic-Craft with decorative glass packages, custom size or 8-foot slab, upgraded hardware, rot-damage repair in the opening)

Every quote from us includes parts, labor, disposal of the old door, and a written line-item breakdown before work starts. If we open up the wall and find rotted sheathing or termite damage (common in older Palm Beach homes near the intracoastal), we’ll stop, show you exactly what we found, and price the additional work before we touch it. No surprise change orders. The Therma-Tru product carries its manufacturer warranty, and our installation is covered by the 36500-Day Done Right Promise: if it’s not done right, we come back and make it right.

We also stock and install parts for PGT, CGI, and CWS door lines, so if your Therma-Tru door is paired with impact-rated side lites from another brand, we can handle the whole assembly without calling in a second crew.

DIY or Call Us?

Here’s the honest split. There are a few things you can safely check yourself: whether the hinge screws have pulled out of the jamb (if they have, a longer screw in the same hole is often all it takes), whether the threshold is adjusted to the correct height, and whether the weatherstripping is pinched or torn. Those are five-minute checks that cost you nothing.

What we don’t recommend is pulling a Therma-Tru door and attempting a full install yourself. These doors weigh 100 to 175 pounds with the glass package, and getting one out of a rotted frame without damaging the rough opening is a two-person job even for a trained installer. More importantly, a door that’s even slightly out of plumb or racked will never seal, never lock, and never survive the next tropical weather event the way it should. If the frame is compromised or the slab is dragging, call (561) 831-7863 and let one of our background-checked installers put a level on it. The estimate is free and there’s no trip charge inside the county.
