This page is for West Park homeowners who already have Therma-Tru windows and need them to perform better, or need them replaced with the same brand’s energy-efficient lines. We’ve worked on Therma-Tru products across Broward County since 2012, including retrofits near Sunview Park where the original single-pane aluminum frames were doing almost nothing against the summer heat load.

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

• Classic-Craft and Fiber-Classic series: seal failure in insulated glass units. The wood-grain fiberglass frames hold up well in West Park’s humidity, but the dual-pane IGUs in units from roughly 2010-2018 often show fogging between the lites after eight to ten years. The desiccant in the spacer saturates faster here than in drier climates. We measure the sightline, order the correct IGU by serial, and replace the glass unit without disturbing the frame or voiding any remaining Therma-Tru glass warranty.
• Smooth-Star entry systems with sidelites: thermal bowing in direct sun. West Park’s southern and western exposures push surface temperatures past 140°F on dark-colored fiberglass. The sidelite glass can develop stress cracks where the frame restrains expansion. We spec tempered or heat-strengthened replacement lites with a lower SHGC coating, and we check the frame’s square before reinstalling to prevent recurrence.
• Impact-rated Therma-Tru units: delamination of the laminated interlayer. The impact glass in coastal Florida units can haze at the edges where moisture breaches the seal, especially if the weep channels were painted shut by a previous owner. We document the condition with photos, source OEM-grade laminated glass or equivalent from our ES Windows and Mr-Glass supply lines, and verify the new unit passes the missile-impact standard before we sign off.
• Low-E coating degradation on older Therma-Tru windows. Pre-2015 units with early sputtered Low-E coatings can show a visible haze or iridescence that reduces clarity and insulating value. The coating itself is failing, not the glass structure. We replace with current-generation soft-coat Low-E with argon fill, which drops the U-factor from roughly 0.48 to 0.30 on a typical double-hung, and we note the improvement on your written quote.
• Weatherstrip compression set on Therma-Tru hinged patio doors. The Q-Lon or bulb seals flatten after years of South Florida UV exposure, letting conditioned air escape and unconditioned air enter. Therma-Tru’s OEM weatherstrip is available but often back-ordered. We stock compatible compression seals from our PGT and CGI parts inventory that match the original performance spec and install without altering the door’s certification.

Our Therma-Tru Energy-Efficient Windows Process

1. 1
   Measured survey. Sonia Raman or a verified crew member arrives in uniform, license number provided in advance. We record rough opening dimensions, frame condition, and existing glass specs. You keep the survey document.
2. 2
   Diagnostics. We test for air infiltration with a smoke pencil, check sash balance and hardware operation, and photograph any seal failure or coating degradation. If the frame is salvageable, we say so. If it isn’t, we say that too.
3. 3
   Parts decision. For glass replacement, we source Therma-Tru OEM serial-matched IGUs when available and cost-effective. For back-ordered or discontinued units, we specify equivalent from our ECO Window Systems or CWS lines that meets the original U-factor and SHGC. We note the source on your written quote.
4. 4
   Installation. We remove the failed unit, clean the glazing rabbet, set the replacement with proper setting blocks and edge clearances, and seal with Dow 795 or equivalent neutral-cure silicone. No shortcuts on the perimeter seal; that’s where the next failure starts.
5. 5
   Testing and documentation. We operate every sash, check the lock engagement, and run the smoke pencil again. We photograph the completed work and upload the record to your job file. The 365-Day Done Right Promise applies from this moment.
6. 6
   Written closeout. The final invoice matches the quote. You receive the photo record, warranty documentation, and our direct line for any callback.
