Therma-Tru Door Installation: The Fort Lauderdale Owner’s Guide
Replacing or installing a Therma-Tru door in Fort Lauderdale typically runs $1,450 to $3,800 installed, depending on the slab, frame, sill, and whether we’re swapping hardware and weatherstripping at the same time. Most Therma-Tru door installations in Broward County are a one-day job once the correct door is on hand, and we stock the most common Therma-Tru replacement parts on our trucks, so we can often handle the full install in a single visit. The way most Fort Lauderdale homeowners discover they need us: a door that suddenly drags on the threshold, a deadbolt that won’t line up with the strike plate, or sunlight you can see through the weatherstrip. That’s usually not a hinge adjustment problem. That’s a door system that has shifted, swelled, or failed in the South Florida humidity, and it’s time to address the door itself, not just the symptoms.
Which Therma-Tru Models This Applies To
Therma-Tru makes a broad range of entry doors, and the installation specifics change depending on which series you have. The most common lines we install and service around Fort Lauderdale are the Classic-Craft, Fiber-Classic, Pulse, and Benchmark series. Classic-Craft and Fiber-Classic are fiberglass door systems, which hold up better than wood in Fort Lauderdale’s salt air and humidity. Pulse is a narrower-profile fiberglass line that works well for the mid-century ranch homes you see in neighborhoods like Victoria Park and Riverside Park. Benchmark is Therma-Tru’s builder-grade line, and it shows up frequently in the planned communities around Plantation and Davie.
Here’s the compatibility gotcha: Therma-Tru slabs are not universal. The door, frame, hinges, and sill are engineered as a system, and mixing a Classic-Craft slab into a Benchmark frame often leaves gaps that weatherstripping won’t close. Before we quote anything, we need the model and size off the hinge-side label or the edge stamping on the slab. If that label is gone, we measure the slab thickness, door width and height, and the hinge spacing, then match against Therma-Tru’s spec sheets. For replacement parts and hardware, OEM Therma-Tru components are always the safest call because the dimensions are exact. Quality aftermarket options exist for things like weatherstripping and sills, but we’re careful with aftermarket hinges and bottom sweeps, because a 3-inch hinge with the wrong offset changes the reveal and the door will never close true.
Signs Your Therma-Tru Door Installation Is Failing
- Drag at the threshold: The door catches when you open or close it. In Fort Lauderdale, this usually means the slab has absorbed moisture or the frame has settled, not that your hinges are merely loose. A door that drags is wearing the threshold and the weatherstrip every time you force it.
- Visible daylight around the perimeter: Stand inside with the door closed and look at the edges. If you can see daylight, your weatherseal has failed, and in Fort Lauderdale’s rainy season that gap is also letting in humid air and running up your cooling bill. A failed seal on a Therma-Tru door often means the frame shifted, not just old gaskets.
- Deadbolt won’t throw without lifting the handle: This is a strike plate alignment problem, and it’s the tell that the door has settled or the hinges have worn. The fix is re-aligning the slab in the frame or replacing worn hinge pins, but if the frame itself has moved, shimming and re-installing the frame is the only durable answer.
- Rust streaks or rot at the bottom corners: On older Therma-Tru installs, water that pools at the sill wicks up and attacks the frame and door bottom. We see this constantly on Fort Lauderdale homes built before 2005, where the original installers skipped the sill pan flashing.
- The door slams or swings on its own: A door that drifts open or closed on its own is out of plumb, and no amount of closer-tension adjustment will cure it. The frame needs to be reset square, which is a full removal and re-installation.
Replacement Cost & What’s Included
In Fort Lauderdale, a full Therma-Tru entry door replacement with the slab, frame, threshold, weatherstripping, and hardware runs roughly $1,450 to $3,800 installed. A slab-only swap on an existing frame that’s still square usually falls between $950 and $1,900. A full frame-and-slab replacement on a high-end Classic-Craft model with impact-rated glass can push past $4,200, and that’s specific to homes in Broward County’s coastal wind zones where the glazing has to meet Miami-Dade impact standards.
What you’re paying for: the door system itself, removal and haul-away of the old unit, sill pan flashing (which we install on every exterior door, no exceptions), shims, foam insulation around the frame, sealant, and all labor. Our price is the written price you approve before any work starts. No revised invoice at the door. If something is discovered once the old door comes out and the job scope changes, we stop and re-quote before we proceed. Every Therma-Tru installation we do comes with the Kingswell Guarantee in writing: if the work is not right within the guarantee period, we come back and fix it at no charge.
DIY or Call Us?
An exterior door installation is not a spring-tension repair, so you won’t get a safety lecture from me about touching your own door. But I’ll be straight with you about where DIY goes wrong. If your Therma-Tru door is dragging or sticking, you can safely check hinge screws for tightness and clean the threshold track. What you should not attempt is pulling the frame, re-shimming, or installing a new slab yourself. A fiberglass entry door system weighs far more than people expect, and when the frame isn’t set perfectly plumb and square, you’ll be chasing the same deadbolt alignment and air leaks for the life of the door. We’ve fixed enough botched DIY installs in Fort Lauderdale to tell you: the door is the cheap part. The labor you pay for is the person who knows why the old one failed and how to keep the new one from doing the same thing.

FAQs
A properly installed Therma-Tru fiberglass door system in Fort Lauderdale typically lasts 20 to 30 years on the slab itself, but the weatherstripping, bottom sweep, and sill usually need replacing every 5 to 7 years because of the heat and humidity. Doors on homes within a quarter mile of the Intracoastal or the ocean may need hardware attention sooner due to salt corrosion. Call (754) 354-5397 and we’ll tell you whether your door has life left or whether replacement is the better money.
Yes, if the slab is sound and the frame is still square, most issues, including weatherstripping failure, hinge wear, and strike plate misalignment, are repairable without full replacement. The call only shifts to replacement when the frame is rotted or the slab has moisture damage. If the frame is still structurally good, we’ll tell you that, and we’ll quote the repair, not the replacement.
A straightforward Therma-Tru door slab and frame replacement on an existing opening takes 4 to 6 hours on site, and full removal with frame replacement is typically done in one day. Custom sizes or impact-rated glass may add a day for glass fabrication. When we schedule your installation, we commit to a real arrival window, not a four-hour block of guessing.
We stock the most common Therma-Tru weatherstripping, bottom sweeps, hinges, and sills on our service vehicles, and we can order any Therma-Tru panel or frame through our manufacturer partnerships. We are an independent installer, not affiliated with Therma-Tru directly, but we install Therma-Tru product alongside our other six manufacturer lines, including PGT, CGI, and CWS, so the right product actually gets matched to the job.
