We don't patch a door that's past its service life - if the panel is original to a house built around 1971, the springs and cable have likely already been swapped once or twice, and the drum and track are the next thing to go. At that point a new install is the honest call, not an upsell.
We measure the rough opening, check headroom and backroom clearance against what the original builder gave you (older Rochelle garages often have less of both than current code assumes), and spec a door and opener that fit the structure as it actually stands, not as a catalog page. Install includes new track, hardware, and a spring set matched to the door's actual weight - not a generic size pulled off a shelf.
