We'll ask what the door is doing - won't open, opens partway, makes a grinding noise, opener runs but nothing moves - and give you a straight read on whether it sounds like a spring, a cable, an opener board, or something in the track. Given the age spread of homes in this area, a lot of calls turn out to be hardware fatigue on a door that's been running since the house was built, and we'll say that if it looks that way.
Sometimes the honest answer is that repair isn't worth it - a panel that's rusted through, or a door where replacement parts for that specific model are hard to source, costs more to patch than to replace. We'd rather tell you that on the first visit than keep billing you for stopgaps. If it's a straightforward fix, we do it that day when the parts are on the truck. If it's not, we'll tell you what we need to order and roughly what that means for timing.
