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.
2. Select the right products
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 Window Replacement: The Hobe Sound Owner’s Guide
Therma-Tru window replacement in Hobe Sound typically runs $340-$780 per opening installed, depending on whether we’re matching a standard builder-grade unit or a custom-sized impact-rated frame. We stock Therma-Tru-compatible sashes, balances, and full frame assemblies on our trucks, and most replacements are measured, ordered, and installed within one to two business days. Most Hobe Sound homeowners discover the problem when a window won’t stay open, fogs between the glass, or the sash slams shut - signs that the balance system or insulated glass unit has failed.
Which Therma-Tru Models This Applies To
Therma-Tru window lines break into two categories we see in Hobe Sound: the builder-distributed Classic-Craft and Fiber-Classic series common in 2015-2022 construction, and the Impact-Rated coastal lines specified for Florida wind zones. The part you need depends on which generation you own. Pre-2019 units used a proprietary tilt-latch balance with a 5/8-inch shoe width; post-2019 shifted to a universal 3/4-inch shoe that accepts aftermarket hardware. Check the etched code in the glass corner - it contains the NFRC rating and a date stamp we cross-reference to the exact balance spec.
We carry both OEM Therma-Tru balances and Amesbury Truth aftermarket equivalents rated for the same cycle count. The aftermarket part saves roughly $40-$60 per sash and carries an identical 10-year warranty. For impact-rated units, we stick with OEM sash packs because the glazing bead profile is proprietary and an imperfect match voids the wind-load certification. Sightline Windows & Doors Hobe Sound is an independent service provider with no affiliation to Therma-Tru.
Before
AfterSigns Your Therma-Tru Window Replacement Is Failing
- The sash drops or won’t stay raised. This is the coil balance failing, usually from corrosion at the attachment point. In Hobe Sound, salt air accelerates this - we’ve replaced balances in homes near Peck Lake at six years that should have lasted twelve inland.
- Fog or moisture between the glass panes. The insulated glass unit (IGU) seal has breached. Once desiccant saturation hits, the spacer corrodes and the thermal performance collapses. The fix is a full sash replacement, not defogging.
- Difficulty locking or visible frame warp. Fiberglass frames resist expansion better than vinyl, but prolonged UV exposure on south-facing elevations can still distort the jamb. We measure the diagonal to 1/16 inch before ordering; anything beyond 3/16 inch and the replacement won’t seat square.
- Air infiltration at the meeting rail. The weatherstrip has compressed or the interlock has worn. Therma-Tru’s dual-fin pile seal degrades faster in high-humidity environments; we upgrade to silicone-treated replacements where the original spec calls for standard pile.
- Cracked or delaminated exterior cladding. The fiberglass substrate is intact, but the acrylic finish has failed. This is cosmetic until water reaches the substrate, at which point the frame integrity is compromised. We document this with photos - Haven Clause 4 - so the owner sees exactly what we found.
Replacement Cost & What’s Included
| Component | Price Range (Installed) |
|---|---|
| Standard balance replacement (per sash) | $180-$260 |
| Insulated glass unit (IGU) replacement | $340-$480 |
| Full sash pack (glass + frame + hardware) | $520-$680 |
| Complete frame-in-frame replacement | $680-$780 |
The range reflects three variables: whether the existing frame is square enough to accept a sash pack, whether impact-rated glazing is required for the Hobe Sound wind zone, and whether we discover water intrusion in the rough opening during removal. Our measured survey - the document you keep - locks the price before we order anything. The 365-Day Done Right Promise covers labor and materials; the manufacturer’s warranty covers the part itself.
DIY or Call Us?
An owner can safely check three things: the etched glass code for the model year, whether the window is under warranty with Therma-Tru directly, and whether the frame is visibly square from the interior. Beyond that, replacement involves risks we flag plainly. Coil balances store significant tension; an uncontrolled release can damage the frame or cause laceration. Impact-rated sashes weigh 40-60 pounds and require two hands plus proper support to prevent glass fracture. Most critically, an improperly seated sash in a wind-rated opening creates a code violation and an insurance exposure.

FAQs
Expect 8-12 years for standard balances, 6-10 years within a mile of salt water. The coil spring itself doesn’t fail; the attachment point corrodes. Call (772) 362-5967 for an exact quote - estimates are free.
Balance systems and IGUs are sealed assemblies; there is no field repair that restores original performance. Frame damage can sometimes be addressed with a sash pack if the rough opening is square. Call (772) 362-5967 for an exact quote - estimates are free.
A balance swap takes 45-60 minutes per window. A full sash pack runs 90-120 minutes including removal, rough-opening inspection, and insulation. We schedule morning starts in Hobe Sound to complete before afternoon thunderstorms complicate exterior work. Call (772) 362-5967 for an exact quote - estimates are free.

Sonia Raman built Sightline on a habit she learned measuring rough openings across Martin County: check it twice before anything gets ordered. Measure it right the first time, and the door closes the way it’s supposed to - every time after that. That standard applies to every Therma-Tru replacement we handle in Hobe Sound.
