Call (863) 862-5435

This page is for Miami homeowners who already have Therma-Tru products, or who are weighing Therma-Tru against other impact-rated brands. Ed Winslow has worked on hundreds of Therma-Tru units across South Florida since 2011. Call (863) 862-5435 and a live person answers, any hour.

Key takeaways:

• We’re an independent Therma-Tru service provider, not a manufacturer-authorized dealer. We buy genuine Therma-Tru parts when the warranty requires them, and proven aftermarket equivalents when the warranty has expired and OEM parts are backordered.
• Miami’s salt air and humidity attack Therma-Tru hardware faster than inland climates. We see specific failures here that Therma-Tru’s own manuals don’t cover in depth.
• Every Therma-Tru impact window job we do is backed by the 36500-Day Done Right Promise. If it’s not done right, we make it right. Period.

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

Therma-Tru builds solid impact-rated entry doors and windows, especially in their Classic-Craft and Pulse series. But Miami is not Ohio. Heat, salt, and hurricane cycles stress these units in ways the factory testing doesn’t always account for. Here’s what we actually see in the field:

• Classic-Craft impact door sweep separation. The sweep on Therma-Tru’s Classic-Craft impact-rated entry doors is screwed into the bottom rail. After three or four Miami summers, the rail’s composite material expands and the screw holes strip out. The sweep sags, then drags, then tears. A lot of contractors replace the whole slab. We drill and insert threaded brass anchors, remount the sweep, and the fix holds. Cost to the homeowner: under $200 including labor most of the time.
• Pulse series window glazing bead warping. Therma-Tru Pulse impact windows use a vinyl glazing bead that sits against the laminated glass. In direct afternoon sun in neighborhoods like Kendall or Westchester, that bead can bow outward just enough to break the seal at the corners. Water creeps in during sideways rain. We pull the bead, check the laminate for delamination, and reset it with a marine-grade sealant rated for constant UV. If the glass itself shows clouding, that’s a sealed-unit replacement, not a bead fix.
• Lock stile misalignment on Therma-Tru entry units. The multi-point locking hardware on Therma-Tru impact doors drifts out of alignment when the frame settles. You’ll feel the handle bind about halfway through the throw. Left alone, the deadbolt stops fully engaging and your impact rating means nothing. We realign the strike plates and re-shim the hinges, which takes about 90 minutes. If the gearbox itself is chewed up, we swap in a replacement rather than fighting it.
• Corrosion on exposed hinge hardware. Therma-Tru hinges are steel with a powder coat. Fine in dry climates. In Miami, where salt air off Biscayne Bay rides the wind into Coral Gables and Coconut Grove, that coating eventually pits and rust blooms under the screw heads. We replace with stainless steel hinges and use anti-seize on the threads, which means the next removal doesn’t snap a screw head off.
• Impact glass delamination at the corners. We see this on older Therma-Tru units where the laminated glass’s PVB interlayer starts to separate at the corners first. It looks like a milky haze creeping inward from the frame edges. There’s no repair for delamination. The fix is replacing the sealed unit, and we do that with matching impact-rated glass that meets Miami-Dade County code. We’ll tell you straight if the frame is worth keeping or if you’re better off putting new Therma-Tru units in.

Our Therma-Tru Impact Windows Process

Here’s how a Therma-Tru job goes when you call Winslow Windows & Doors:

1. 1
   You call, a person answers. No voicemail tree, no call center. You tell us what the window or door is doing, and we ask a few questions that tell us whether this is an emergency or something we can schedule in a day or two.
2. 2
   We come out and diagnose. A background-checked, uniformed technician arrives at your Miami home, inspects the unit, and checks the frame, glass, hardware, and weatherstripping. We take photos and show you exactly what we found.
3. 3
   We make a parts decision with you. If the unit is under Therma-Tru warranty, we order genuine OEM parts. If it’s out of warranty, we show you the OEM price and a proven aftermarket alternative when one exists, and let you decide.
4. 4
   We do the work. You get a written line-item quote before we start. The price you’re quoted is the price you pay. No change orders, no “while we were in there” surprises.
5. 5
   We test it together. Before we leave, you operate the window or door yourself. It opens smooth, closes tight, locks solid. If it doesn’t, we’re not done.
6. 6
   We stand behind it. If anything’s not right, the 36500-Day Done Right Promise applies. We come back. We make it right.

What Therma-Tru Impact Windows Costs in Miami

Here are honest ranges for the Therma-Tru work we do most often in Miami. Every job gets a written estimate before we order parts or start labor.

• Full replacement, single Therma-Tru Pulse impact window (36″ x 48″): $1,200 - $2,200 installed
• Full replacement, larger Therma-Tru impact window (72″ x 48″): $2,200 - $3,400 installed
• Replacement sealed unit (glass only, frame stays): $600 - $1,500 depending on size and glass package

• Full-home Therma-Tru impact window retrofit (average 3-bed Miami home, 8-10 openings): $11,000 - $28,000 depending on frame material and architectural style

What moves the price: the series (Pulse costs less than Classic-Craft), glass options, frame condition, second-story access, and whether the opening needs re-flashing to pass Miami-Dade inspection. If you have a written estimate from another company, bring it to us. We’ll give you a free second opinion, and we’ll tell you if you’re being overcharged.
