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

In San Antonio, a Therma-Tru impact garage door replacement typically runs $2,400 to $5,800 installed, depending on door width, reinforcement panel options, and whether the existing track and opener remain serviceable. We carry Therma-Tru-compatible impact garage doors and the hardware that goes with them, and our techs can usually match and install within a matter of days once we’ve confirmed the model at your home. Most owners call us after a spring lets go, a panel cracks under a storm shot, or the door starts binding on one side and refuses to close square. Hale Windows & Doors is an independent service provider, not affiliated with Therma-Tru, but we install and service their doors constantly because the brand holds up better than most in Texas heat and hailstorms.

Which Therma-Tru Models This Applies To

Therma-Tru builds impact-rated garage doors under a few distinct series, and the part that fits one rarely fits the other without modification. The key spec is the door’s wind-load rating and panel profile, not just its width. We see mostly the Pulse and Classic Craft garage lines in San Antonio subdivisions, along with fiberglass-composite doors that mimic wood grain but carry an impact rating. If your manual’s long gone, check the inside of the door itself. A silver compliance sticker near the bottom corner will list the model, series, and pressure rating in psf, like “Design Pressure +26.0/-29.0.” Most Therma-Tru impact doors measure 8 feet wide by 7 feet tall or 16-by-7 for two-car openings, but we’ve done enough 9-by-8 carriage models in Terrell Hills to know the measurement comes first and the catalog comes second.

One compatibility gotcha worth knowing: Therma-Tru changes its hinge and roller spacing between manufacturing years, and a 2016 door and a 2022 door of the same nominal size can use different hardware. We match the panel stamping, not the brochure. When the door’s too far gone to patch, OEM sections are the clean route. But for rollers, hinges, and bottom seals, quality aftermarket equivalents from Clopay or Amarr often fit identically and cost 20 to 30 percent less. We stock both, and we’ll tell you which one makes sense for your door.

Signs Your Therma-Tru Impact Garage Door Is Failing

• Door lifts unevenly or binds mid-track. This is usually a failed spring or worn rollers. Impact doors weigh more than standard doors, so the spring works harder and gives out sooner. A door that sits crooked is also stressing the track bolts every time it moves.
• Visible cracking or splitting near a panel edge. Therma-Tru’s composite skin is impact-rated, but San Antonio hail storms can punch a cone-shaped crack that spreads on the next close. Water gets in, the interior foam swells, and the panel loses rigidity fast.
• The door groans, snaps, or pops during a cycle. A popping sound at the spring line is often a rusted coil unwinding unevenly. A groan near the hinges means the hinge pins are eating themselves against the track.
• Bottom seal is flattened, torn, or missing chunks. You’d be surprised how much July heat sneaks under a garage door in San Antonio when the bottom astragal is shot. A worn seal also lets monsoon water and scorpions in, both of which are known to ruin a perfectly good afternoon.
• The door sags an inch or more on one side when open. That’s a structural or cable issue, not a cosmetic one. On an impact-rated door, a sagging panel means the internal brace has separated from the skin, and the door won’t perform to its wind rating anymore.

Replacement Cost & What’s Included

An installed Therma-Tru impact garage door in San Antonio runs $2,400 to $5,800 for a two-car single door, with carriage-style composite models at the higher end and flush panels at the lower. A single-car door ranges $1,700 to $3,200. Here’s how that breaks down:

• Door panel assembly: $1,200 to $2,900 depending on size, finish, and impact rating
• Track, springs, and cables: $350 to $700 (we always replace springs when we hang a new door)
• Labor and haul-away of the old door: $450 to $800
• Weatherstripping and perimeter seal: $80 to $200

Every quote is a written, line-item price before any work starts. No change orders, no “we found something” add-ons. If the install isn’t right, the 365-Day Done Right Promise covers fixing it, no argument needed. We pull the old door, install the new one, test it through full cycles, and hand you the manual and warranty paperwork before we leave.

DIY or Call Us?

Some things here are safe to check yourself: whether the door operates smoothly by hand with the opener released, whether the bottom seal is cracked, whether the rollers are visibly worn. But the springs on a Therma-Tru impact door are under enough tension to take a finger or a face clean off, and the cables can whip. We don’t hand out spring-replacement instructions because handing them out gets people hurt. The honest split is this: inspect what you can see, don’t touch what’s under load. Spencer Odell has pulled enough snapped-spring shrapnel out of San Antonio garages to say that plainly. If the door’s misbehaving, call (361) 348-8929 and let us look at it. Estimates are free, and we’ll tell you exactly what it costs before any tool comes off the truck.
