Brandon sits about 8 miles from our Sioux Falls base, closer than most of the towns on our route, including Tea and Harrisburg. On site, we start by checking the spring's wire size, coil length, and inside diameter against the door's weight and track setup rather than assuming the old spring was sized right to begin with - it's not uncommon to find a door running a spring that was undersized from the original install. We replace the spring, inspect the cables and drums for wear from the failure, and reset the door's balance by hand before testing it through a full cycle with the opener disengaged. We lubricate the moving hardware while we're in there, since a dry roller or hinge is often sitting right next to the spring that just failed. We don't sell a full door replacement on a spring call unless the panels or track are actually failing - if the spring's the only problem, that's the only thing we replace.
