The median house in Highland Village went up around 1993, which puts most garage doors here in one specific bracket: steel raised-panel doors, usually a 16x7 double on the front of the house, hung on torsion springs that were standard for that decade of construction. That's a heavier door than the wood or single-layer steel you'd find in an older neighborhood, and the springs sized for it are wound tighter. When one of those breaks, the door doesn't just stick - it can drop hard, because there's more door for the spring to hold. We come out from Coppell, about 10 miles south, with springs sized for that mid-90s torsion setup already on the truck, along with the standard track and roller hardware that matches doors of that age. We diagnose on site, price the fix before we touch anything, and do the repair in the same visit when the part is one we carry.
