This page is for homeowners who already have Therma-Tru products and need them to perform under Miami-Dade’s HVHZ code, whether that means fixing a failed sash, replacing a compromised frame, or upgrading to full impact-rated assemblies. If the spec isn’t on the page, it isn’t part of the job. Call (754) 354-6649 to schedule your free measured survey.

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

• Impact sash corner separation on Classic-Craft Canvas Collection units. The composite frame material expands at a different rate than the reinforced corner keys in South Florida’s wet heat. We see this most in Miami Gardens homes built between 2016 and 2020 where the original install didn’t account for the 3/16-inch thermal movement gap Therma-Tru specifies. Our fix: remove the sash, re-key with stainless corner brackets, and re-bed with neutral-cure silicone rated for the movement. We document the gap measurement on your survey.
• Laminated glass delamination in Pulse doorlites after salt-air exposure. Miami Gardens sits close enough to the Atlantic that coastal salt accelerates the edge seal breakdown on non-stainless spacer systems. The glass looks fogged at the perimeter first, then spiders inward. We replace with tempered-laminated units using warm-edge spacers and stainless intercepts, and we note the exposure rating on your written scope so the replacement matches your insurance documentation.
• Multi-point lock misalignment on Therma-Tru Fiber-Classic entry systems with impact sidelites. The three-point lockset drags because the composite stile creeps under sustained wind pressure. Homeowners force the handle and strip the gearbox. We realign the keeps to current factory spec, replace the gearbox with OEM or verified-equivalent, and shim the frame to transfer load back to the jamb rather than the hardware.
• Water intrusion at the sill pan on full-light impact patio door systems. The weep channels clog with construction debris and trap water against the composite sill. In Miami Gardens, where summer rain falls faster than the 5-inch-per-hour threshold most sills are tested at, this shows up as staining on the interior track. We pull the panel, re-flash with code-compliant sill pan material, and verify drainage with a calibrated pour test. Your photo record includes the before and after flow rate.
• Impact-rated astragal failure on double-door configurations. The T-astragal seal compresses permanently after repeated positive/negative pressure cycling, losing its design pressure rating without visible damage. We measure the compression set with a feeler gauge and replace the astragal assembly if it’s lost more than 1/8-inch of rebound. This is a pass/fail item on our post-install test report.

Our Therma-Tru Impact Windows & Doors Process

1. 1
   Measured survey. Sonia Raman or a verified crew member arrives with a printed license number, measures the rough opening to 1/16 inch, and records frame squareness, sill level, and wind-exposure rating. You keep the survey sheet.
2. 2
   Written quote. We specify Therma-Tru part numbers where OEM is indicated, or cross-reference quality aftermarket equivalents where the factory part is back-ordered or discontinued. The quote and the survey are the same document. No separate numbers appear later.
3. 3
   Parts procurement. For impact-rated assemblies, we verify the replacement carries the Miami-Dade NOA or Florida Product Approval matching your original installation year. We note the approval number on your scope.
4. 4
   Install with documentation. Crew works to the written spec, photographing each phase: rough opening condition, flashing detail, fastener pattern, and final sightline alignment. Photos upload to your record by end of day.
5. 5
   Performance test. We cycle the unit through full open, close, and lock operations; check sash squareness with a digital level; and verify the impact rating label is legible and matched to your documentation.
6. 6
   365-Day Done Right Promise activation. Your warranty document specifies the exact coverage, the response path, and the crew license number responsible. No verbal assurances. Everything in writing.
