Therma-Tru Impact Windows & Doors in West Palm Beach: What to Know First

We provide independent Therma-Tru impact windows and doors service in West Palm Beach, typically scheduling measured surveys within 48 hours of your call and completing most repairs or replacements within one to two weeks of quote acceptance. Our written quotes start with the measured survey you keep, and the final invoice matches that document exactly. If the number isn’t on the page, it isn’t in the price.

Call (561) 354-3861

This page is for Therma-Tru owners in West Palm Beach who need impact-rated windows or doors repaired, replaced, or upgraded to meet current hurricane codes. That includes homes along Flagler Drive, in El Cid, Flamingo Park, and throughout the surrounding neighborhoods where salt air, afternoon storms, and the 2027 Florida Building Code cycle are pressing concerns. Call (561) 354-3861 to schedule your free measured survey.

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

  • Impact sash corner separation in Classic-Craft Canvas Collection units. The multi-layer construction that gives Classic-Craft its thermal performance can delaminate at the mitered corners after repeated thermal cycling in West Palm Beach’s 90-degree-plus summer afternoons. We see this most often on west-facing doors in El Cid and Northwood. Our fix: remove the sash, re-glue with structural epoxy rated for Florida humidity, and re-seal with OEM-compatible backer rod and sealant. If the corner joint has spread beyond 3/16 inch, we replace the sash.
  • Glazing bead shrinkage on Fiber-Classic impact units. The compression-set PVC glazing beads on early Fiber-Classic impact windows relax after seven to ten years in direct UV, creating a gap between the glass edge and the frame that lets wind-driven rain bypass the primary seal. We replace with current-spec beads that use a dual-durometer design, or we move to a wet-glaze installation on larger openings where bead retention is critical.
  • Multi-point lock misalignment on Dura-Guard impact entry systems. The three-point locking hardware on Dura-Guard doors drifts out of spec as the composite frame settles, particularly on installations where the rough opening wasn’t shimmed to our tolerances. We measure the keeper positions with a digital height gauge, then mill custom strike plates rather than forcing the lock to meet a shifted frame. This preserves the impact rating; grinding the keepers does not.
  • Drainage channel clogging in Therma-Tru patio door sills. The weep system in sliding impact patio doors packs with salt and pollen during West Palm Beach’s March-through-May bloom season, trapping condensation against the sill track and accelerating corrosion of the stainless rollers below. We pull the active panel, clear the weeps with controlled air and nylon picks, and replace rollers with OEM or equivalent 440-grade stainless units. We document the before condition with photos you receive.
  • Impact glass spider cracks from thermal stress, not impact. Tempered impact-rated glass in Therma-Tru units can fracture from edge contact with a hardened setting block or from nickel-sulfide inclusions in heat-soaked glass that failed to relieve. We distinguish thermal from impact failure by crack pattern and edge inspection, then file the documentation your insurance or warranty claim requires. Replacement uses the same ASTM E1996 rating as the original.

Our Therma-Tru Impact Windows & Doors Process

Our Therma-Tru Impact Windows & Doors Process
  1. 1
    Measured survey. We arrive with a laser measure, moisture meter, and level, and record rough opening dimensions, frame squareness, and wall condition. You keep this document. Sonia Raman reviews every survey before quote issuance.
  2. 2
    Diagnostics with parts decision. We identify the Therma-Tru series, manufacturing date (stamped on the hinge or frame edge), and whether the failure is field-repairable. OEM parts carry the original warranty but carry longer lead times; our quality aftermarket alternatives meet the same impact specs and ship faster. We name both options with prices.
  3. 3
    Written quote. The quote references the measured survey by date and includes line-item labor, materials, permit fees if applicable, and exclusions. Haven Clause 1: the price before work starts is the price after.
  4. 4
    Installation or repair. Our background-checked, uniformed technicians arrive with license numbers provided in advance. We protect floors, contain dust, and work to the manufacturer’s fastening pattern and sealant schedule.
  5. 5
    Testing and documentation. We cycle operable units twenty times, check lock engagement with feeler gauges, and photograph the completed condition. You receive the photo record within 24 hours.
  6. 6
    365-Day Done Right Promise activation. The Haven Standard warranty document is dated and signed before we leave. If adjustment is needed, we return under the Promise, not as a favor.

We’ve installed and serviced 18,000+ openings since 2012, and a measurable share of those have been Therma-Tru products in West Palm Beach homes where the original installer is no longer traceable. Our technicians carry the current Therma-Tru parts catalog and know which series used which glazing system, which matters when you’re trying to match a 2017 installation to current code.

Because we also specify PGT, CGI, CWS, and ES Windows, we can compare your Therma-Tru repair quote against a same-opening replacement in another line, with performance data for both. The Haven Standard governs either path: verified crews, evidence on every job, and no surprise between quote and invoice. Our 365-Day Done Right Promise is stamped on the paperwork, not offered verbally after the fact.
