Therma-Tru Impact Garage Doors Nationwide

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

We stock and install Therma-Tru impact garage doors throughout Houston, with most complete door replacements running $2,400 – $5,800 installed depending on size, finish, and reinforcement package. If you’re reading this, you likely have a Therma-Tru door that took a hit during storm season, a panel that’s delaminating from humidity, or rollers that sound like gravel every time the door moves. The short version: we can match your existing Therma-Tru setup or upgrade it to full wind-rated impact spec, and we’ll put the price in writing before any work starts.

Which Therma-Tru Models This Applies To

Therma-Tru doesn’t manufacture garage doors under its own label the way it does entry doors, so when Houston homeowners say “Therma-Tru impact garage door,” they usually mean one of two things: a Therma-Tru entry door system on a garage-adjacent opening (common in Heights bungalows and newer builds near Sugar Land), or a garage door spec’d through a Therma-Tru dealer package that pairs their framing with a wind-rated door from a partner manufacturer. Either way, the compatibility gotcha is the same: the rough opening and jamb depth must match the existing door slab, not just the panel width. A 16-foot door from 2012 sits in a different jamb profile than a current 16-foot unit, and forcing the swap creates exactly the kind of racked track and seal failure we see after the first Houston summer.

On the parts side, we stock Therma-Tru-compatible weatherstripping, corner seals, bottom sweeps, and frame components. For full door swaps, we work with the eight lines we carry: PGT and CGI for impact-rated garage doors (both Miami-Dade certified), CWS for mid-tier wind-rated options, and Therma-Tru proper for the entry-door side of the garage system. OEM Therma-Tru weatherstripping runs about 30 – 40% more than a quality aftermarket equivalent, and in our experience the failure point is rarely the material itself, it’s the install. We’ll tell you straight when OEM is worth it and when it isn’t.

Signs Your Therma-Tru Impact Garage Door Is Failing

• Panels are bowing or delaminating at the edges. Houston humidity gets behind the laminate face and separates it from the core. Once you see a ripple along the bottom panel, water is already working its way in, and that panel won’t pass another wind event without flexing past its rating.
• The door no longer seals tight against the jamb. A door that was plumb when installed and now shows daylight at the top corners means the frame or the track has shifted. In Houston’s clay soil, minor foundation movement is routine, and the door absorbs it first.
• You hear grinding or metal-on-metal from the rollers or hinges. Impact doors carry more steel than standard doors, so when a roller bearing fails, you hear it in the kitchen before you see it. Ignoring it dents the track, and a dented track on a wind-rated door is a write-off, not a repair.
• Impact glass or the reinforced panel shows a stress crack radiating from a corner. Even a small crack means the laminated layer has been compromised. The door will still operate, but it won’t hold its wind rating, which is the entire point of the investment.
• The door hangs slightly crooked when halfway open. That’s almost always a stretched or broken spring, and a high-tension spring on an impact door carries more load than a standard residential spring. This is the one symptom where we say stop using the door immediately and call us.

Replacement Cost & What’s Included

For a full Therma-Tru-garage-door-system replacement in Houston, we quote a written line-item price that covers the door, track, rollers, springs, weatherstripping, labor, and haul-away. Here’s how it breaks down:

• Single-car impact-rated door (8×7 to 9×7): $2,400 – $3,600 installed
• Double-car impact-rated door (16×7 to 18×7): $3,800 – $5,800 installed
• Parts-only repair (rollers, hinges, seals, single panel replacement): $180 – $650 depending on the component and whether it’s OEM or aftermarket
• Spring replacement on an impact door: $340 – $520, including both springs (always done as a pair)

The range comes down to three things: door size, whether you need full Miami-Dade wind certification documented for insurance, and what we find when we open the track. A door that’s been grinding for a year often needs track replacement too, and we’d rather quote that honestly on day one than surprise you mid-job. Every replacement we do in Houston carries our 365-Day Done Right Promise: covered in writing for a full year, and if it fails, we come back at no charge.

DIY or Call Us?

The honest split: you can safely check your bottom seal, clean the tracks, and tighten visible hinge bolts. What you should not touch is anything under tension. Impact-rated garage doors use high-cycle, high-tension springs that store a dangerous amount of energy. A spring that lets go during a DIY attempt will take fingers, eyes, or worse, and it happens faster than you can react. We’ve seen the aftermath, and it’s not worth saving $200. The same goes for panel replacement on a wind-rated door: hitting the right torque spec and keeping the jamb plumb under load is the difference between a door that holds its rating and one that fails when you need it most.

If the symptom is a seal, a roller, or a hinge you can reach without touching the spring, and you’re comfortable with a socket wrench, go ahead. Anything spring, track, or panel related, call us at (432) 278-2282. Elliot Vance reviews every estimate before it goes out, so the number you get is the number the crew works to. Measure twice, seal it right, and the window does the rest of the talking.
