This page is for Jupiter homeowners who already have Therma-Tru products and need to improve thermal performance, replace failed units, or match existing trim profiles during an energy upgrade. If you are comparing brands, we also specify PGT, CGI, CWS, and ES Windows by performance tier and price range, not by margin. Call (772) 362-5402 to schedule your free measured survey, or bring us any written competitor estimate for a free second opinion.

How Therma-Tru Products Fail - and How We Fix Them

• Decorative glass seal failure in Therma-Tru Fiber-Classic and Smooth-Star entry sidelites. The simulated divided lite (SDL) grids and decorative glass packages in these lines use a dual-seal system that degrades faster in Jupiter’s salt-air corridor than inland specs predict. We see fogging between the decorative and tempered outer lites most often on east-facing elevations along A1A and the Inlet District. Our fix: remove the sash, document the seal breach with frame readings, and source either OEM replacement insulated glass units or specify a laminated Low-E upgrade that eliminates the air gap entirely.
• Low-E coating degradation in Therma-Tru vinyl double-hungs from the 2015-2019 production window. These units shipped with a soft-coat Low-E surface on surface #2 that can oxidize when the edge seal breathes in high-humidity cycles. The symptom is a hazy iridescence visible at oblique angles, not condensation. We identify this with a glazing inspection light during survey, then quote a replacement IG with hard-coat Low-E or a suspended film package depending on the homeowner’s SHGC target.
• Argon loss in Therma-Tru patio door panels without measurable breach. The sliding and swinging patio door lines use a rolled-edge metal spacer that conducts more than warm-edge alternatives; in Jupiter’s thermal cycling, the pressure differential slowly pumps argon through intact but permeable edge seals. We detect this with a deflectometer reading showing elevated U-factor despite clear glass. Our repair specifies a warm-edge stainless spacer and recharge with argon-krypton mix, or full IG replacement if the frame is distorted.
• Sash warping in Therma-Tru vinyl casements with dark exterior laminates. The darker color profiles absorb more solar gain than the white base vinyl was originally spec’d for, and Jupiter’s afternoon thunderstorms followed by rapid re-radiation create differential expansion. The sash bows enough to compromise the weatherstrip compression. We measure the sightline deviation, then either reshape the sash with heat and brace (if within 3/16 inch) or quote a replacement sash in a lighter color with matching interior woodgrain foil.
• Intermittent condensation in Therma-Tru impact-rated laminated units. The PVB interlayer in impact glass can trap moisture at the laminate edge if the unit was stored vertically before installation, a handling issue we see more with Therma-Tru’s older Florida distribution chain than with current stock. The condensation appears at the glass perimeter, not center-of-lite. We verify with a moisture probe, then replace the IG with a unit that has a proper desiccant fill and stored-flat documentation from our supplier.

Our Therma-Tru Energy-Efficient Windows Process

1. 1
   Measured survey you keep. Sonia Raman or a verified crew member arrives with license number on record, takes frame readings with a digital caliper to 1/32 inch, and notes existing trim, sill condition, and any lead or asbestos concerns. You receive this document before any quote is prepared.
2. 2
   Glazing diagnostics. We test U-factor with a deflectometer, inspect for seal failure patterns specific to your Therma-Tru series, and photograph every opening. The photo record becomes part of your job file under Haven Clause 4 (Evidence on Every Job).
3. 3
   Parts specification: OEM or verified equivalent. For current Therma-Tru series, we quote OEM insulated glass units and hardware. For discontinued lines, we source from our verified aftermarket partners or cross-specify from PGT, CGI, CWS, or ES Windows if the opening allows. We document the source and warranty term for each component in writing.
4. 4
   Written scope with fixed price. The measured survey and the quote are the same document. The price does not change unless you change the scope. Haven Clause 1: Have it in writing.
5. 5
   Installation and live testing. Crews arrive uniformed and background-checked per Haven Clause 3. We install, seal, and test operability and air infiltration before cleanup. You sign the completion checklist.
6. 6
   Photo record and 365-Day Done Right Promise. Documented photos upload to your file within 24 hours. If anything is not done right, we make it right. Measure once, quote it straight, install it right - that’s the whole business.

Our technicians are background-checked, uniformed, and identified by license number before arrival. We have handled Therma-Tru products since 2012, including a stretch of impact-replacement work along Jupiter’s Indiantown Road corridor that taught us more about Florida wind-load specs than any classroom did.

The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy. Our eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - mean we specify by what your opening requires, not by what is in stock. Live phone coverage is available 24/7. Calls are answered by a person, not a queue.
