We run this job from Skokie, about 10 miles out to Mount Prospect. That distance doesn't change the repair itself, but it's part of why we ask for a clear description of the problem - a snapped spring and a failing opener board call for different parts, and we'd rather bring the right one on the first trip than make two. Most single-repair jobs on a house from this suburb's 1969-era stock - one spring, one opener, one bent section of track - run under two hours once the truck is on site and the door is open enough to work on. A full door replacement takes longer, and if the opening is an odd size or the door has to be special-ordered, that can mean a second trip to install once the door arrives. We don't promise a specific arrival window here since we're coming from Skokie rather than sitting in Mount Prospect already, but the job length itself doesn't change based on where we started.
