AfterTherma-Tru Impact Windows & Doors in Boca Raton: What to Know First
We install and service Therma-Tru impact windows and doors in Boca Raton as an independent provider, with typical project turnaround of two to four weeks from measured survey to final inspection. Every job starts with a written price based on a survey you keep; the quote and the invoice are the same document. We do not quote over the phone without seeing the opening.
This page is for Boca Raton homeowners who already have Therma-Tru products and need replacement, repair, or upgrade to impact-rated units, or who are comparing Therma-Tru against other lines we carry. Call (561) 200-8592 to schedule a free measured survey.
How Therma-Tru Products Fail - and How We Fix Them
- Impact sash corner separation on Classic-Craft and Fiber-Classic entry door systems. The fiberglass skin and polyurethane core expand at different rates after repeated heat cycling in Boca Raton’s UV exposure. We see this most in west-facing entries in neighborhoods like Boca Del Mar. We remove the sash, re-glue with structural epoxy rated for Florida humidity, and re-seal with OEM gaskets rather than generic bulb seals that harden in two seasons.
- Insulated glass seal failure in Therma-Tru sidelites with Low-E coatings. The argon escapes, the glass fogs, and the Low-E performance drops. This is not a frame problem; it is a glazing problem. We order the exact glass package from Therma-Tru’s glazing partner or, when lead times stretch past eight weeks, source a tested equivalent with matching U-factor and SHGC ratings documented in writing.
- Multi-point lock misalignment on Smooth-Star patio door systems. The keeps and deadbolts drift out of plane as the composite frame settles, especially in homes built on the fill soils common east of Military Trail. We do not shim the hardware; we reset the frame to plumb and re-machine the strike locations, because a misaligned multi-point is a failed impact test waiting to happen.
- Water intrusion at the sill pan on Therma-Tru entry units without proper flashing integration. In Boca Raton’s driving rain events, water finds the gap between the sill pan and the subsill. We document the intrusion path with photos, remove the unit, install a compatible sill pan with end dams, and seal with Sika or Tremco compatible with Therma-Tru’s fiberglass substrate, not generic caulk.
- Impact-rated lite frame corrosion on coastal Therma-Tru installations within two miles of the Intracoastal. The aluminum lite frames in impact configurations corrode where the anodizing is compromised at screw holes. We replace with stainless or clad frames depending on the series, and we document the original fastener torque to prevent repeat failure.
Our Therma-Tru Impact Windows & Doors Process
- 1
Measured survey. Sonia Raman or a crew lead records every rough opening dimension, frame squareness, and sightline measurement. You keep the survey sheet. Measure it twice, write it down, then we can talk price.
- 2
Written scope and price. We specify the Therma-Tru series, glass package, hardware finish, and any frame modifications. The price is fixed. Haven Clause 1: the measurement and the quote are the same document.
- 3
Parts decision. We default to OEM Therma-Tru components. If lead times exceed project deadlines, we present a quality aftermarket alternative with matching spec sheets, never substituting without written approval.
- 4
Installation by verified crews. Haven Clause 3: background-checked, uniformed technicians with license numbers provided before arrival. No day-labor rotation.
- 5
Testing and documentation. Every unit is operated, locked, and inspected for seal integrity. We leave a photo record of the installation, the written warranty, and the 365-Day Done Right Promise stamped under the Haven Standard.
- 6
Cleanup and final walkthrough. The opening is left clean, the old unit is hauled, and the invoice matches the written quote to the dollar.

Why Boca Raton Homeowners Call Sightline Windows & Doors Boca Raton for Therma-Tru Work
We are not a Therma-Tru dealer. We are an independent installer who specifies Therma-Tru when the opening calls for it, alongside PGT, CGI, CWS, and ES Windows when those lines fit better. That independence means we do not push inventory.
Our crews know the difference between a Fiber-Classic frame and a Classic-Craft frame without reading the label, because we have replaced both in Boca Raton homes from Broken Sound to Boca Harbour. The 365-Day Done Right Promise is not a courtesy; it is Haven Clause 5, written into every contract. The photo record is not an upsell; it is Haven Clause 4, standard evidence. And the price you sign is the price you pay, because Haven Clause 1 does not allow for change orders based on “unforeseen conditions” that a proper survey would have caught.

FAQs
No, provided the installation follows Therma-Tru’s published guidelines and uses specified components. We document every fastener, sealant, and glass package to warranty standards, and we keep those records for the life of the installation. Call (561) 200-8592 to review how we handle documentation on your specific series.
OEM frames and sashes typically ship in four to six weeks; glass packages with custom Low-E coatings can run six to ten weeks. We maintain relationships with regional distributors in Miami-Dade and Broward to shorten that when possible, and we always quote a realistic lead time in writing before you commit.
Replace when the frame is out of square by more than a quarter-inch, when corrosion has compromised the lite frame structurally, or when the cost of component repairs exceeds 60% of replacement. Repair when the failure is isolated to glass, hardware, or seal, and the frame is sound. We tell you which category you’re in after the survey, not before.
Sometimes. Therma-Tru has updated profiles and skin textures over the years; an exact aesthetic match is not always possible. We bring sample chips to the survey and document the closest available match, with your approval, before ordering. If the match is not acceptable, we discuss full-set replacement.
We provide the Miami-Dade or Florida Building Code approval number for every impact-rated product we install, and we verify it against the physical label on the unit at delivery. If the numbers do not match, we do not install. Call (561) 200-8592 to schedule a survey and review the documentation process.
