New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Hobe Sound pairs proven product lines with our own installing crews for lasting performance - and a price we put in writing.
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 Installation: The Hobe Sound Owner’s Guide
Therma-Tru window installation in Hobe Sound typically runs $340-$780 per opening depending on series, size, and whether the existing frame is square. We stock Therma-Tru-compatible frames, sashes, and hardware for same-day installation on most standard sizes. Homeowners usually discover a problem when the sash won’t stay open, they feel air moving at the meeting rail, or they spot fog between the glass that wasn’t there last season.
Which Therma-Tru Models This Applies To
Therma-Tru organizes its window lines by frame material and performance tier, and the part you need depends on which line is in your wall. The Classic-Craft and Fiber-Classic collections use pultruded fiberglass frames with proprietary corner gussets that differ from the vinyl profiles in the Benchmark and Ovation series. We see the most service calls in Hobe Sound for the Fiber-Classic and Benchmark lines installed between 2015 and 2022.
To identify your exact model, check the etched code in the glass corner or the label on the frame header. The first four digits indicate the series; the next two are the year of manufacture. A “FC15” prefix means Fiber-Classic, 2015 production. The OEM part number is useful, but not required. We carry quality aftermarket equivalents that meet the same DP-50 pressure rating and carry the same 10-year seal warranty at roughly 30% less cost. The catch: aftermarket sashes won’t match every custom color Therma-Tru offered in 2016-2018, particularly the “Mahogany Grain” and “Oak Grain” exterior finishes. If color match is critical, we order OEM and add two days to the lead time.
Before
AfterSigns Your Therma-Tru Window Installation Is Failing
- Sash drops or won’t stay open. The balance system, typically a constant-force coil spring in Therma-Tru double-hungs, has lost tension. In Hobe Sound’s salt air, we see these corrode faster than the manufacturer rates them, especially on east-facing windows that catch morning spray off the Atlantic.
- Fog or moisture between glass panes. The insulated glass unit (IGU) seal has failed. Once argon escapes and ambient air enters, the desiccant saturates within weeks. The IGU must be replaced; defogging sprays are temporary and void any remaining warranty.
- Air infiltration at the meeting rail or frame perimeter. Compression weatherstrip has flattened or the sill track has worn a groove. On Therma-Tru vinyl units, the pile height is 0.270 inch; if you can slide a dime between sash and frame with the window locked, the seal is gone.
- Difficulty locking or latching. The keep or cam has shifted due to frame settlement, or the multipoint hardware has corroded. We check frame squareness first: a 1/8-inch twist across the width will bind every mechanism.
- Visible frame distortion or corner separation. Fiberglass expands and contracts less than vinyl, but poor shim placement during original installation concentrates stress at the corners. We’ve inherited this exact problem from previous installers on homes near Gomez Avenue where the frame was fastened too tightly to the buck.
Replacement Cost & What’s Included
Here is what Therma-Tru window installation costs in Hobe Sound, with parts and labor separated:
| Component | Price Range |
|---|---|
| IGU replacement (standard 36″ × 48″) | $340-$480 |
| Sash replacement (double-hung, standard size) | $420-$620 |
| Full frame replacement (per opening) | $580-$780 |
| Balance system repair (both sides) | $180-$260 |
| Multipoint hardware replacement | $220-$340 |
The range reflects three variables: whether the existing frame is plumb and square, whether the interior trim can be preserved, and whether the wall condition requires sill pan replacement. We pull permits when required by Martin County and include that cost in the written scope. Every job carries our 365-Day Done Right Promise under the Haven Standard, and you receive the measured survey, the written quote, and a documented photo record before we leave.
DIY or Call Us?
An owner can safely check three things: verify the model code, confirm the symptom is consistent (not seasonal swelling), and clear weep holes with a pipe cleaner if water is pooling on the sill. Beyond that, Therma-Tru windows present two genuine hazards. The IGU is heavy, typically 35-50 pounds for a standard double-hung, and the sash must be tilted or removed without twisting the frame. Second, the balance system is under spring tension; releasing it without a locking tool can snap the coil and damage the jamb liner.

FAQs
Fiberglass frames typically perform 20-25 years; vinyl units 15-20 years. Salt air and UV exposure on unshaded east or south exposures shorten that by 3-5 years. The IGU seal warranty is 10 years from manufacture, not installation, so a 2017 unit may have limited coverage remaining. Call (772) 362-5967 and we’ll check your date code against the warranty terms at no charge.
IGU seal failure and balance system fatigue require replacement of those components, not repair. Frame corner separation can sometimes be reinforced if caught early, but we document the repair and note that full replacement may follow within 3-5 years. We do not recommend repairs that conceal a problem you’ll face again at greater cost. Call (772) 362-5967 for a written assessment.
Component replacement (IGU, sash, or hardware) takes 2-3 hours per opening. Full frame replacement requires 4-6 hours plus cure time for sealants. We schedule one opening per day for occupied homes to maintain security and climate control. Call (772) 362-5967 to book a specific date.
We carry standard-size IGU blanks, balance systems, and multipoint hardware for Fiber-Classic and Benchmark series on every Hobe Sound vehicle. Custom sizes and 2016-2018 color-matched sashes require next-day delivery from the regional distributor in West Palm Beach. Call (772) 362-5967 with your model code and we’ll confirm stock before we dispatch.
Sonia Raman has measured more rough openings in Martin County than she cares to count, and she still measures each one twice before ordering. Measure it right the first time, and the door closes the way it’s supposed to - every time after that.
