We start by checking the track and jamb hardware before touching the spring or opener, because on a house this age that's where a problem that looks electrical or spring-related often actually starts. If it's a spring job, we replace the spring, check the cable and drum condition at the same time, and add containment cable if it isn't already there. If it's the opener, we test the travel limits and force settings rather than just swapping the unit, since a misadjusted opener can look like a dying motor. We service what we install, and the Brandon shop handles every call out this way - there's no separate branch in Town 'n' Country, just the one truck and the one 18-mile drive out.
