Most of the houses we get called to in Irondale went up around 1994, which puts them square in the builder-grade boom years. That means a specific kind of torsion spring: single-spring setups rated light, installed by the builder to meet a budget, not to last three decades. We carry replacement torsion springs sized for the standard 7-foot steel sectional doors that came standard in that era of construction, plus the matching end bearings and center brackets that wear out alongside them. We don't stock exotic hardware for custom doors here because Irondale's stock doesn't call for it - it's consistent, mid-90s builder product, door after door. If you've got an older torsion bar or a wood door from before that build wave, we may need to order the part, and we'll tell you that up front instead of guessing on your driveway.
