Therma-Tru Impact Windows & Doors in Davie: What to Know First

We install and service Therma-Tru impact windows and doors in Davie as an independent provider, with most measured surveys scheduled within 48 hours and written pricing delivered before any work begins. A typical Therma-Tru full-frame replacement in Davie runs $890-$2,400 per opening depending on series, size, and whether the existing frame can accept a retrofit insert. We do not quote over the phone; Haven Clause 1 requires that the measurement and the written price be the same document.

This page is for Davie homeowners who already have Therma-Tru products and need impact-rated replacement or repair, or who are comparing Therma-Tru against other lines we carry. You’ll find real series names, real failure modes we’ve documented, and real dollar ranges. Call (754) 254-8492 to schedule your measured survey.

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

• Classic-Craft and Fiber-Classic door slabs swell at the bottom rail in Davie’s summer humidity. The pultruded fiberglass skin separates from the polyurethane core when standing water sits against the threshold, common in homes near Pine Island Ridge with poor drainage grading. We cut back the damaged core, epoxy-bond a new composite bottom rail, and reset the door with a composite or aluminum threshold that sheds water. OEM bottom rails are available; we document the repair with photos for your record.
• Smooth-Star entry doors lose impact rating when the steel-edge reinforcement corrodes. The galvanized steel band that runs the lock stile rusts from the inside out in coastal Davie, where salt air penetrates fastener holes. The door still looks intact but no longer meets Miami-Dade HVHZ standards. We replace the entire door unit with a new Smooth-Star or cross-reference to a PGT or CGI equivalent if lead times stretch. We test the new install with a calibrated pressure gauge and record the reading.
• Dura-Protect multi-point locking sets bind after two to three years. The zinc alloy gearbox wears where the deadbolt throw meets the keep, especially on doors facing west that take afternoon thermal expansion. We stock quality aftermarket gearboxes from Truth Hardware that match the Dura-Protect footprint; OEM multipoint sets are also available but carry a six-to-eight-week lead time. We always test the full throw cycle under load before we leave.
• Impact-rated sidelites separate at the glazing tape line. Therma-Tru’s sidelites use a wet-glaze system with structural silicone; in Davie, the black aluminum trim can reach 140°F in direct sun, accelerating tape creep. We remove the lite, clean the rabbet to bare metal, and re-glaze with Sika or Dow structural silicone rated for the full pressure cycle. We photograph the wet-bed thickness with a feeler gauge for the job record.
• Cross-bore hardware prep loosens in Fiber-Classic stiles. The composite stile is dense but not as rigid as wood; heavy lever sets gradually wallow out the 2-1/8″ bore. We bore out the damaged area, epoxy-bond a hardwood or composite dowel, and re-drill to specification. For repeat failures, we recommend upgrading to a solid-core Classic-Craft stile or switching to a PGT entry door with an extruded aluminum stile.

Our Therma-Tru Impact Windows & Doors Process

1. 1
   Measured survey. Sonia Raman or a verified crew member arrives in uniform with license number visible, records every opening to 1/16″, and notes frame condition, wall type, and existing trim. You keep the survey sheet.
2. 2
   Written scope and price. We specify Therma-Tru series, glass package, and hardware by part number. The quote is the survey with prices added; nothing changes unless you change the scope.
3. 3
   Parts decision. We quote OEM Therma-Tru components and quality aftermarket alternatives where they exist, with lead times named in writing. You choose; we document.
4. 4
   Installation. Crews work to the measured survey, not to field cuts. We photograph frame readings, fastener patterns, and sealant beds at each opening.
5. 5
   Testing and sign-off. Every operable unit is cycled twenty times. Impact-rated doors get a pressure test where accessible. We review the photo record with you before final invoice.
6. 6
   365-Day Done Right Promise. The Haven Standard covers labor and materials. If it is not done right, we make it right. The photo record proves what was done.

Why Davie Homeowners Call Sightline Windows & Doors Davie for Therma-Tru Work

We are independently owned and operated under the Haven Standard, not a franchise, and we have installed and serviced Therma-Tru products in Davie since we opened here. Sonia Raman measures every job personally when possible; she learned glazing at Los Angeles Trade-Technical College and spent two decades in the field before founding Sightline in 2012. Her crew knows the difference between a Fiber-Classic stile that can be repaired and one that needs replacement, and they will tell you which before any work starts.

We also carry PGT, CGI, CWS, and ES Windows. If your Therma-Tru lead time is unacceptable or the series is discontinued, we can cross-reference to a verified equivalent without sending you to another contractor. Every tech is background-checked and uniformed; every job leaves a documented photo record; every price is written before a tool is lifted. Measure it right the first time. Everything else follows from that.
