A straightforward torsion spring swap, one spring or two, on a door that's otherwise in decent shape, is usually a job we can finish in one visit once we're on site with the right spring in hand. Bartlett runs about 7 miles from our Schaumburg shop, farther than closer stops like Roselle at 3 miles or Hanover Park at 4, so factor that into when we can get there rather than how long the repair itself takes once we arrive. If the drums, cables, or bearing plate are also worn, or if the door's an older extension-spring type that needs a fuller rework, that adds time. We'll tell you before we start if we think the job runs past the standard visit, not after.
