A straightforward torsion spring swap on a standard double door, the kind common to Port Salerno's 1984-era housing stock, is usually a same-visit fix once the truck is on-site - the spring itself doesn't take long to replace when the size is on hand. What stretches the timeline isn't the repair, it's whether we're carrying the right spring for your door on the first trip.
Older extension-spring setups, if your house predates the torsion-standard era, can take longer to diagnose because the failure point - a frayed cable, a worn pulley, the spring itself - isn't always obvious at a glance the way a snapped torsion spring is. Either way, you're not left with an open garage overnight waiting on a part we don't carry; the common sizes for this era of house are the ones we stock.
