A standard dual-cable replacement on a torsion door, once we're on site, is usually finished in under two hours. We don't carry a published response-time guarantee for Bartlett, since we run the job from Hoffman Estates, about 7 miles out, rather than keeping a crew stationed in town. That drive doesn't change the repair time once we're there, but it's part of scheduling a same-day visit versus a next-day one.
If the drum or spring also needs replacing, add time for us to source the part and rebalance the whole system before the door's back in regular use. We'd rather tell you it's a half-day job up front than rush a torsion rebuild to hit an arbitrary window.
