Therma-Tru Door Installation: The Miami Owner’s Guide

A Therma-Tru door installation in Miami typically runs $1,200 to $3,800 fully installed, depending on whether we’re replacing a single entry door, a full frame, or adding impact-rated glass and hardware. Most jobs are completed same-day once the door and frame are on hand. We keep common Therma-Tru hinges, thresholds, and adjustable sills on the truck, and we can source any series-specific component within days, not weeks.

The way Miami homeowners usually find us is the same way: the door that worked fine in December binds in July, or the sweep has pulled away and the afternoon rain finds its way inside. Sometimes it’s simpler. The deadbolt throws, but the door rattles in the frame. You’ve lived in the house twenty years. You know what the door should feel like. It doesn’t feel like that anymore.

We’re an independent installer, not a Therma-Tru franchise. That matters when it comes to matching parts. We’re free to tell you whether the OEM threshold is worth the extra cost or whether a quality aftermarket equivalent will outlast the original in Miami humidity. We give you the choice on paper, with prices, before anyone signs anything.

Key Takeaways:

• Installed Therma-Tru door replacement in Miami: $1,200 to $3,800 depending on door, frame, and impact glass.
• We stock common Therma-Tru parts on the truck: hinges, threshold caps, sweeps, and adjustable sills.
• Same-day installation in most cases, once the door and frame are confirmed.
• Both manufacturer warranty layers registered in writing before the truck leaves your driveway.
• 90-Day Done Right Promise on every Therma-Tru install we perform.

Which Therma-Tru Models This Applies To

Therma-Tru builds entry doors across several lines: the Classic-Craft, Fiber-Classic, Smooth-Star, Pulse, and the newer Benchmark series. The fiberglass skin on a Classic-Craft is not the same as the one on a Smooth-Star, and the slab thickness varies accordingly. A hinge that fits a Smooth-Star will not automatically fit a Pulse door, even if both are 36 by 80.

Here’s the compatibility gotcha most people miss: Therma-Tru has used at least three different hinge mortise patterns over the years, depending on the door’s production year and fire rating. A 2005 Classic-Craft hinge layout won’t line up with a 2018 model. We don’t guess. When we come out, we check the label on the hinge edge of the door, measure the slab thickness, and match the part to the exact production run before drilling anything.

On the OEM versus aftermarket question: Therma-Tru thresholds and sills are well built, but their adjustable cap systems wear out in coastal air. We regularly replace just the vinyl cap and retain the original aluminum base. That’s a $45 fix versus a $300 full threshold. But if the base itself is pitted or the leveling screws are seized, we’ll tell you the full replacement is the honest call. We carry both options and quote them side by side, on paper, with the manufacturer’s stated warranty duration written next to each line.

One more Miami-specific note: if your door is in a high-rise or within a wind-borne debris zone, the slab alone won’t solve the code requirement. You need the entire assembly, including frame, glass, and hardware, rated as a unit. We verify that against Miami-Dade product approvals before we order anything.

Signs Your Therma-Tru Door Installation Is Failing

• The door binds at the latch edge in summer but closes fine in winter. This is thermal expansion, and it’s normal to a point. But if you’re lifting the handle to get the latch to clear the strike plate, the hinges have settled or the frame has shifted out of square from seasonal ground movement under the slab. The fix is shimming the hinges or adjusting the jamb, not planing the door.
• You can see daylight under the door or feel a draft at the threshold. The adjustable sill cap has compressed or cracked. Miami sun beats down on south-facing entries, and the vinyl cap degrades faster here than the manufacturer’s average lifespan assumes. In the southern half of the county, we see caps fail in eight to ten years, not twelve.
• The door swings shut on its own, or won’t stay open. Usually, the top hinge has been installed out of plumb or the jamb has racked. It’s not a sign the door is “bad.” It’s a sign the original install wasn’t done right. We re-hang and re-shim, and the door stays where you put it.
• The sweep drags across the tile or leaves a wear mark in the floor. Most installers cut the sweep to the maximum length and let the floor do the trimming for them. We set the sweep so it clears the finished floor by an eighth of an inch. No drag. No gap. No water line after a hard Miami downpour.
• The door rattles when the A/C kicks on and pressure changes inside the house. The weatherstripping has lost its memory, or the threshold was never adjusted to meet the new sweep height. Either way, the air you’re paying to cool is leaving through the entry. We see it on nearly every original-builder door from the mid-1990s.

Replacement Cost & What’s Included

Here’s the straight pricing for Therma-Tru door installation in Miami:

• Slab-only replacement, existing frame stays: $1,200 to $1,800 installed, including new hinges, sweep, and threshold adjustments. If the existing frame is square and the brick mold is sound, this is the smart money.
• Full frame-and-slab replacement, standard entry: $2,200 to $3,000 installed, including new brick mold, casing rework, and foam insulation around the jamb. This is the common case for doors that have been in place for fifteen-plus years.
• Impact-rated Therma-Tru assembly, Miami-Dade approved: $2,800 to $3,800 installed, depending on glass lite count and hardware rating. The storm panel or shutter conversation goes away because the door itself is the rated product.

The range is driven by three things: whether the frame is salvageable, what glass package the door carries, and whether the hardware is standard or multi-point. A multi-point lock assembly adds $200 to $400 in parts alone, but it’s the right call for a door that’s catching wind off Biscayne Bay.

Every quote includes the door or part, all hardware, the labor to hang and adjust, and cleanup. Both manufacturer warranty layers get registered in writing before we leave, and our 90-Day Done Right Promise backs the workmanship. If something isn’t right when you close that door every night for the next three months, we come back and make it right. No paperwork fights.

DIY or Call Us?

You can safely check a few things yourself: whether the threshold cap screws turn, whether the sweep is torn, and whether the hinge screws are tight in the jamb. Loose hinge screws are behind a surprising number of service calls, and that fix takes a screwdriver and five minutes.

Beyond that, this is where DIY goes sideways. A full-frame reset means pulling the brick mold, checking the rough opening for rot, and setting the new jamb plumb in two planes while shimming correctly. Get the shim pattern wrong, and the door binds forever. Get the sill height wrong, and water finds the subfloor. We’ve rebuilt frames that homeowners attempted with a level from the hardware store and a Saturday’s worth of optimism. The materials cost twice by the time we’re done.
