Therma-Tru Impact Garage Doors: The Palm Beach Owner’s Guide

We stock and install Therma-Tru-compatible impact garage doors throughout Palm Beach, with the typical installed price landing between $2,800 and $6,500 depending on size, panel design, and whether we’re replacing a full door or retrofitting hardware on an existing assembly. Most Palm Beach owners discover they need service when a door stops sealing flush against the track after a storm, or when the impact glass in a windowed panel develops a crack that spreads in the salt air. The good news is that a replacement door or panel swap is usually a one-day job, and we carry the most common Therma-Tru track profiles on our trucks so we can diagnose on the first visit.

Which Therma-Tru Models This Applies To

Therma-Tru builds impact garage doors in two primary series that we see in Palm Beach homes: the Classic-Craft full-panel line and the Pulse series, which runs on a reinforced aluminum track with heavier gauge rollers. The compatibility gotcha most owners run into is that the Classic-Craft uses a 2-inch-thick door section, while the Pulse uses 1¾-inch, and the weatherstripping is not interchangeable between them. Before you order parts anywhere, check the manufacturer label on the inside edge of the top section. It will list the series name and a production code, and that code is what we use to match the correct panel stamping and swing-arm geometry.

We’re an independent service provider, not affiliated with Therma-Tru, which matters for one reason: we have no incentive to push an OEM part when a quality aftermarket one works better for your door. For hinges and roller brackets, we often recommend aftermarket versions that use marine-grade stainless steel, which holds up far better against Palm Beach salt spray than the factory-installed zinc-plated hardware. For the panels themselves, the door skin and insulation core, we recommend genuine Therma-Tru parts, because the foam density and the profile stamping need to match to keep the wind rating and the seal line consistent.

Signs Your Therma-Tru Impact Garage Door Is Failing

• Dragging or binding on one side of the track. This usually means a roller bracket has worn unevenly or a hinge pin has corroded in the salt air. Left alone, the door will rack and eventually jump the track.
• Visible cracking around the window frame seals. Impact-rated glass is designed to take a hit, but the seal around the frame degrades under Palm Beach UV, and water gets behind it, damaging the insulation core.
• Light visible through the top or side seals at noon. That gap means the weatherstripping has compressed or torn, and it’s no longer holding the rated wind pressure. In a real blow, that gap is where uplift starts.
• Rust bleeding from the bottom panel corners. Therma-Tru panels are steel-skinned, and once the factory coating is breached near the ground seal, the panel edge can corrode fast in Florida humidity. It’s cosmetic at first, then it’s structural.
• The door drifts down after being opened halfway. On a spring-assisted Therma-Tru door, this means the spring has lost tension or is about to let go. This one needs a professional immediately, never a DIY adjustment.

Replacement Cost & What’s Included

For a single-panel replacement on a Therma-Tru Classic-Craft in Palm Beach, you’re looking at $850 to $1,400 installed, depending on width and finish. A full door replacement runs $2,800 to $6,500, with the biggest cost drivers being door size, whether you have windowed panels, and whether we need to convert the track system from the older zinc hardware to stainless. Our quotes include the door, all mounting hardware, weatherstripping at every seal point, demolition and haul-away of the old door, and a written parts-and-labor warranty. We give a line-item quote before any work starts, and the price you approve is the price on the final invoice. No change orders, no surprise fees after we start pulling the old door off.

DIY or Call Us?

There are things an owner can safely check before picking up the phone. You can look for loose bolts at the track brackets, check if weatherstripping is visibly torn, and note whether the door balances evenly when disconnected from the opener. What you should not do is touch the torsion spring, adjust cable tension, or try to reshape a bent track. A torsion spring on a full-weight impact door stores enough energy to cause serious injury if it releases while you’re working on it. That’s not a lecture, it’s just the honest reason we carry the right winding bars and a healthy respect for the job. If your Therma-Tru door is failing, call (561) 831-7863 and we’ll send someone who does this work every week, not once a decade.
