1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.

Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

Therma-Tru Door Installation: The Hobe Sound Owner’s Guide
Therma-Tru door installation in Hobe Sound typically runs $1,800 to $4,200 for a complete entry system replacement, with most standard fiberglass slab-with-frame jobs falling in the $2,400 to $3,100 range. We stock Therma-Tru-compatible frames, sills, and hardware on our trucks, and we can usually measure and begin fabrication within 48 hours. Most owners discover their door is failing when the fiberglass skin starts delaminating at the bottom rail, the composite jamb bows from moisture intrusion, or the adjustable sill stops sealing against driving rain during Hobe Sound’s summer squalls.
Which Therma-Tru Models This Applies To
Therma-Tru organizes its residential line into series families, and the part you need depends on which family your existing door belongs to. The Classic-Craft series uses a denser polyurethane core with a hardwood edge frame; the Smooth-Star series carries a different jamb profile and a PVC-wrapped composite frame that swells differently than Classic-Craft when it takes on water. The Fiber-Classic series, still common in Hobe Sound homes built between 2015 and 2020, uses an earlier-generation composite jamb that is not interchangeable with current Smooth-Star jambs despite similar exterior dimensions.
To identify your series, check the hinge-side jamb for a stamped manufacturing date and series code, or measure the slab thickness: Classic-Craft runs 1-3/4 inches with a distinct beveled edge detail, while Smooth-Star is also 1-3/4 inches but with a squarer profile. The OEM part numbers are printed on a label behind the strike plate or on the top edge of the door slab, though these labels often degrade in Florida humidity after six to eight years.
We carry both OEM Therma-Tru components and quality aftermarket equivalents from Endura and Zabitat for sills and weatherstrip systems. For the jamb itself, we specify OEM because the mortise locations and wall thickness tolerances vary enough that aftermarket jambs create alignment problems we have had to correct on inherited jobs in Hobe Sound’s Jupiter Island-adjacent properties. Sightline Windows & Doors Hobe Sound is an independent service provider and is not affiliated with Therma-Tru.
Before
AfterSigns Your Therma-Tru Door Installation Is Failing
- Water staining at the bottom corners of the interior jamb. This usually means the composite sill cap has cracked or the end-seals have separated from the jamb legs. In Hobe Sound, where afternoon rain hits doors with sustained 25-mph wind, a compromised sill seal will push water behind the interior trim within two or three storms.
- The door slab rubs the head jamb or strike-side jamb seasonally. Therma-Tru’s adjustable hinges can compensate for minor frame movement, but if you are adjusting twice a year, the composite jamb is likely taking on moisture and expanding. We see this pattern frequently in homes near Peck Lake where salt air accelerates the cycle.
- Delamination of the fiberglass skin, starting at the bottom rail or lock stile. The fiberglass itself does not rot, but the adhesive bond between skin and core fails when water sits in the rail cavity. Once the skin lifts, the structural core is exposed and the door’s impact rating is compromised.
- Drafts at the perimeter even with the door fully closed and latched. Therma-Tru’s bulb-style weatherstrip compresses permanently after five to seven years in Florida UV. The replacement weatherstrip must match the kerf width exactly; 1/8-inch variance and the seal will not seat.
- The sill threshold flexes or squeaks underfoot. The adjustable aluminum cap rides on a composite base, and the adjustment screws corrode in coastal environments. A frozen adjustment screw means the sill cannot be tuned to meet the door bottom as the slab settles.
Replacement Cost & What’s Included
| Scope | Typical Range in Hobe Sound |
|---|---|
| Slab replacement only (rehang in existing frame) | $1,800 - $2,600 |
| Slab + jamb replacement, standard 6’8″ opening | $2,400 - $3,400 |
| Full entry system with sidelite, impact-rated | $3,800 - $5,200 |
| Sill replacement only (component repair) | $340 - $580 |
| Weatherstrip replacement, complete perimeter | $180 - $290 |
What drives the range: whether the existing frame is square within 1/8 inch over the height of the opening, whether the rough opening needs reframing for impact-rated hardware, and whether the interior trim can be salvaged or must be replaced. Our written quote itemizes each line - slab, jamb, sill, hardware, labor, trim - and the total you sign is the total on the invoice. Haven Clause 1: the measurement and the quote are the same document. Every Therma-Tru installation we complete in Hobe Sound carries the 365-Day Done Right Promise and leaves a documented photo record of the rough opening, the shim pattern, and the finished seal test.
DIY or Call Us?
There is one thing a homeowner can safely check: the sill adjustment screws. If they turn freely and the threshold still meets the door bottom, the sill may just need cleaning and lubrication. Everything else - jamb replacement, slab hanging, weatherstrip kerf matching - goes wrong in predictable ways we have been called to fix.
A Therma-Tru slab weighs 85 to 110 pounds depending on core density, and the hinges must be mortised to a depth of 5/32 inch with a tolerance of plus-or-minus 1/64 inch or the door will bind. More critically, an impact-rated installation requires specific fasteners into the structural framing, and the failure mode of a misinstalled door in a storm is not cosmetic. We do not recommend DIY for jamb or slab replacement; the risk to the opening’s structural integrity and the door’s warranty coverage is substantial. If you are unsure what you are looking at, call (772) 362-5967 and we will walk through it. Estimates are free, and we will give you the written price before any work starts.
FAQs
Twelve to eighteen years for the fiberglass slab itself, but the sill, weatherstrip, and jamb components typically need attention at six to ten years in coastal Martin County. Salt air and UV exposure degrade the organic components faster than the fiberglass skin. Call (772) 362-5967 for an exact assessment of your specific door - estimates are free.
Component repairs are practical when the slab is sound and only the sill, weatherstrip, or threshold cap has failed. If the jamb is bowed or the slab has delaminated, replacement is the cost-effective path; patching those failures produces callbacks we do not accept under our Haven Standard. Call (772) 362-5967 for an exact quote - estimates are free.
A standard slab-and-jamb replacement in an existing opening takes one day, assuming the rough opening is square and no structural reframing is required. Impact-rated hardware and multi-point lock systems add a second day for adjustment and testing. We arrive with the measured survey you already approved, and the crew verifies every dimension before uncrating the new unit.
We stock sills, weatherstrip kits, threshold caps, and hinge sets for the Classic-Craft, Smooth-Star, and Fiber-Classic series. Complete slabs and jambs are ordered to measured specifications - we do not carry pre-hung inventory because every opening in Hobe Sound has settled differently, and a stock unit is a compromise we do not make. Measure it right the first time, and the door closes the way it’s supposed to - every time after that.
