Therma-Tru Door Installation: The Plantation Owner’s Guide
Therma-Tru door installation in Plantation typically runs $1,850-$4,200 for a complete entry system replacement, with most standard fiberglass slab-and-frame jobs falling between $2,400 and $3,100. We stock Therma-Tru-compatible frames, sills, and hardware kits on our trucks, and we can usually schedule measured surveys within 48 hours. Most homeowners in Plantation realize their Therma-Tru door needs attention when the fiberglass skin separates from the frame at the hinge side, the sill cap cracks after years of wet-season pooling, or the multipoint lock no longer draws the slab tight against the weatherstrip - problems that start small and accelerate once the composite core begins taking on moisture.
Which Therma-Tru Models This Applies To

Therma-Tru has manufactured fiberglass entry doors in dozens of series since the 1990s, and the critical detail for Plantation homes is whether your unit is a Classic-Craft, Smooth-Star, or Fiber-Classic series door. Classic-Craft uses a denser polyurethane core with hardwood edge stiles; Smooth-Star is all-composite with no wood elements; Fiber-Classic sits between them with a wood-composite hybrid frame. The model number is stamped on the hinge edge of the slab or on a foil label behind the lock bore - look for a code starting with CC, SS, or FC followed by the door size.
The OEM-vs.-aftermarket question matters specifically for Therma-Tru because their Composite Outerband frame system uses a proprietary 4-9/16″ jamb depth with a composite cap that standard wood jambs cannot replicate. We source factory-matched frames from Therma-Tru distribution, but we also stock heavy-gauge composite aftermarket jambs from Endura that meet the same performance spec at roughly 15% lower material cost. For the sill, we use OEM Therma-Tru adjustable aluminum sills on coastal-facing entries and aftermarket composite sills on interior-facing doors where wind-driven rain is less severe. The multipoint hardware is the one place we rarely substitute: Therma-Tru’s MP series multipoint locks use a unique 45mm backset and 92mm center-to-center spacing that aftermarket hardware rarely matches without modification.
Before
AfterSigns Your Therma-Tru Door Installation Is Failing
- Visible delamination at the lock stile or hinge edge. The fiberglass skin separates from the stile core, usually starting at a fastener point. In Plantation’s humidity, this gap draws moisture into the polyurethane core, which then swells and accelerates the separation. We see this most often on west-facing doors in Jacaranda and Plantation Acres where afternoon sun cycling stresses the bond.
- Water staining or soft spots at the bottom rail. The bottom rail is the only wood element in many Fiber-Classic doors, and once the end-seal tape degrades, capillary action wicks water from the sill into the rail. By the time you see the stain, the rail is typically compromised and the door is no longer square in the frame.
- Multipoint lock bolts no longer retracting smoothly or failing to engage the strike. The internal actuator rods in Therma-Tru’s MP hardware corrode in salt air, particularly on homes within two miles of the coast. The lock mechanism itself is fine; the rods bind and eventually snap at the elbow joint.
- Daylight visible around the weatherstrip, or the slab rattles in a closed position. This indicates frame racking or sill settlement. In Plantation’s sandy soils, we see this after minor foundation shift, but it can also mean the original installer failed to shim the hinge jamb plumb and the weight of the door has slowly pulled the frame out of square.
- The door drags or binds seasonally, worse in summer. This is not normal expansion. It usually means the composite frame has absorbed enough moisture to swell beyond its designed tolerance, or the sill cap has compressed permanently and the door is now riding low in the frame.
Replacement Cost & What’s Included

| Scope | Price Range in Plantation |
|---|---|
| Standard fiberglass slab replacement (existing frame sound) | $1,850-$2,600 |
| Slab + composite frame (full prehung system) | $2,400-$3,400 |
| Slab + frame + impact-rated sidelite | $3,200-$4,200 |
| Multipoint lock hardware replacement only | $340-$580 |
| Sill cap or full sill replacement | $280-$520 |
These ranges include the measured survey you keep, the written scope with line-item pricing, removal and disposal of the existing unit, installation per Therma-Tru’s published tolerances, and the documented photo record. What drives the spread: door size (standard 3/0 x 6/8 versus 8-foot or double units), whether the frame needs replacement or just adjustment, and whether we are matching an existing sidelite or transom configuration. Every quote is fixed; the number on the proposal is the number on the invoice. Haven Clause 1.
The 365-Day Done Right Promise covers labor and installation materials. Product warranties run through Therma-Tru directly: lifetime limited on the fiberglass slab, 10 years on the frame, 5 years on the finish coat. We register the warranty and deliver the documentation as part of the photo record.
DIY or Call Us?
There is one thing a homeowner can safely check: the screw tightness at the top hinge. A loose top hinge is the most common cause of frame racking, and a #3 Phillips driver will tell you in thirty seconds whether the hinge is pulling away from the jamb. If the screws spin freely or the hinge leaf moves, the door has likely been operating out of plumb long enough to oval the screw holes. That is where DIY should stop.
Everything else on a Therma-Tru door carries real risk. The slab weighs 90-140 pounds depending on size and glass option; a solo lift risks back injury and certain damage to the fiberglass skin. The multipoint lock system is under spring tension - not garage-door-spring dangerous, but enough to launch a bolt into your hand if you disassemble it without relieving the mechanism. And the composite frame is unforgiving: cut it wrong, shim it wrong, or fail to seal the sill pan to Florida building code, and you have a leak path that will not show itself until the next driving rain.
We are an independent service provider, not affiliated with Therma-Tru. We install to their spec because it is the correct spec, not because we are required to.

FAQs

A properly installed Therma-Tru fiberglass door typically lasts 25-30 years in Broward County, though the finish coat will need attention every 7-10 years and the weatherstrip every 5. The multipoint hardware is usually the first component to fail in coastal air; we replace more lock actuators in Plantation’s eastern neighborhoods than anywhere else in our service area. Call (754) 704-3597 and we will inspect the hardware condition during your free estimate.
Sometimes. A delaminated slab can be injected and clamped if the core is still dry, and a sagging frame can be re-shimmed if the composite has not swelled. But once the bottom rail takes on water or the sill pan has leaked into the subfloor, replacement is the only fix that addresses the underlying damage. We document what we find with photos and give you both options in writing. Call (754) 704-3597 to schedule the inspection.
Most standard installations are completed in one day, with the door off the truck and operational by evening. Double units, impact-rated sidelites, or frame conditions requiring rot repair add a second day. We do not promise same-day completion on full replacements; the work requires drying time for sealants and proper shimming that cannot be rushed. Call (754) 704-3597 to confirm scheduling for your specific opening.
We stock standard Therma-Tru slab sizes, composite frames, sills, and multipoint hardware in the most common configurations. Specialty glass, custom sizes, or Classic-Craft oak-grain finishes typically require a 5-7 day order from distribution. We confirm stock status during the measured survey so there are no surprises on installation day. Call (754) 704-3597 to check availability for your model.
Measure it right the first time, write it down, and the installation takes care of itself. That is how Sonia Raman has run Sightline since 2012, and it is why every one of the 18,000+ openings we have touched leaves a documented record the homeowner can refer to years later. If your Therma-Tru door is showing any of the symptoms above, call (754) 704-3597 to schedule your free measured survey and written estimate.
