Most Darnestown calls are a straight swap: matched torsion springs (never just one, even if only one broke - the other is the same age and close behind), new safety cables, and a balance check on the opener's force settings afterward so it doesn't keep straining. If the opener itself is the failure - not the spring - and it's an older chain-drive unit, we'll tell you honestly whether a new logic board is worth it versus a full opener swap; past a certain age, chasing one burned-out part on an opener that's going to need the next part in a year isn't a good use of your money. We don't replace full door sections or re-frame a sagging track on the first visit - that's a separate, planned job, not an emergency repair, and we'll say so rather than stretch an emergency call into something it isn't.
