This page is for Pinecrest homeowners who already have Therma-Tru products and need them to perform as impact-rated assemblies - whether that’s a failed window after a storm cycle, a door that won’t latch under pressure, or a full upgrade to meet current Miami-Dade HVHZ requirements. We are not affiliated with or authorized by Therma-Tru; we are an independent service provider that knows this product line from measured survey to final screw.

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

• Classic-Craft and Fiber-Classic door slabs with delaminated skins. The fiberglass skin separates from the polyurethane core at the bottom rail, especially on south-facing entries in Pinecrest where afternoon rain pools against the threshold. We see this on homes near Pinecrest Gardens where the original install skipped end-sealing. Our fix: remove the slab, re-bond with structural epoxy rated for Florida humidity, and rehang with composite shims that won’t wick moisture.
• Smooth-Star entry doors with warped stiles after impact cycling. The medium-density fiberboard stiles absorb moisture through micro-cracks in the finish, then expand unevenly during heat cycles. This is the door that “used to close fine” but now needs shoulder pressure. We replace the affected stile with an engineered composite component, not wood, and re-seal with a UV-stable coating specified for HVHZ exposure.
• Impact-rated sidelites with seal failure and fogging. Therma-Tru’s sidelite assemblies use a warm-edge spacer system that can creep under sustained thermal stress - common in Pinecrest homes with dark exterior colors. The argon escapes, condensation forms, and the impact laminate degrades from the edge inward. We replace the insulated glass unit with a new OEM-spec assembly, re-tape with butyl, and verify the DP rating hasn’t been compromised.
• DoorLite frames cracking at the corner screws. The decorative glass frames on Therma-Tru doorlites use a PVC composite that becomes brittle after 8-12 years of UV exposure. In Pinecrest, that’s accelerated by the limestone substrate’s reflective heat. The corner screws pull through, the frame gaps, and the impact glass loses its bite. We install a reinforced composite retrofit frame with stainless steel corner brackets - not a caulk patch that fails in six months.
• Multi-point locking systems with corroded deadbolts. Therma-Tru’s multi-point hardware is sourced from several OEMs depending on production year; the zinc-alloy deadbolts in 2015-2019 units corrode aggressively in salt-air environments. Pinecrest is inland, but the prevailing southeast breeze carries enough salt to pit the mechanism. We identify the OEM stamp on the faceplate, source the correct stainless replacement, and re-time all three locking points so the door compresses evenly against the weatherstrip.

Our Therma-Tru Impact Windows & Doors Process

1. 1
   Measured survey you keep. Sonia Raman or a verified crew member arrives uniformed with license number visible, records every frame dimension, sightline measurement, and existing condition with photos. You get the printed survey before we leave.
2. 2
   Diagnosis with model identification. We locate the Therma-Tru production sticker - usually on the hinge stile or top rail - and cross-reference the series, year, and original glass spec. This determines whether OEM parts are still available or if we specify a quality aftermarket equivalent.
3. 3
   Written scope and price. The quote references the survey document by date and technician. The price is fixed; no change orders, no “while we’re here” additions. Measure twice. Quote once. No surprises at the invoice.
4. 4
   Parts procurement and scheduling. OEM Therma-Tru components ship from Ohio in 5-10 business days; we stock common aftermarket alternatives for faster turnaround when the customer approves. We schedule install only when parts are in hand - not “sometime next week, maybe.”
5. 5
   Installation with photo documentation. Every step is photographed: old unit out, rough opening condition, new unit set, shimming pattern, fastener schedule, sealant application, and final operation test. The photo record uploads to your job file within 24 hours.
6. 6
   365-Day Done Right Promise activation. The Haven Standard warranty document is signed, dated, and emailed. If the door drags, the window leaks, or the lock binds within one year, we return and make it right. No paperwork chase.

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

We’ve installed and serviced 18,000+ openings since 2012, and enough of them were Therma-Tru products that our crews recognize the common failure patterns without consulting a manual. When a Pinecrest homeowner calls about a door that won’t seal after a storm, we know to check the multi-point timing first - because we’ve seen the same corrosion on three other homes in the neighborhood.

The Haven Standard governs every job: written price before work starts, verified crews with visible license numbers, evidence on every visit, and no surprises. If Therma-Tru parts are back-ordered, we can specify equivalent performance from PGT, CGI, CWS, or ES Windows - eight manufacturer lines total, chosen by what the opening requires, not by what we have in the warehouse. Our 365-Day Done Right Promise is stamped on every invoice, not offered as a favor.
