Water leaking through Garage walls and door. Who should I contact to fix this?

It's been raining heavily for the whole day today and we just saw water leaking through garage door and walls. Should I call a general contractor to fix this type of stuff? Who would be able to diagnose the issue? The leaks through the door can be resolved by replacing the door but what about other locations? I looked outside and the siding seemed fine. I could not find any obvious cracks. I am also scared as this leak is pretty close to the electric panel.
Would home warranty cover this...
