What gets checked before a repair is quoted
A good repair visit starts with the whole door, not just the symptom you noticed first. If the opener strains, the issue may be a weak motor, but it may also be a heavy door, worn rollers, a binding track, or spring tension that is no longer balanced. Mars checks the door by hand, looks at cables, drums, hinges, rollers, brackets, photo eyes, and opener travel before separating the must-fix safety items from optional improvements.
