Basement Leak in STR

[Joe Stout]

Hey everyone! Got a basement leak in my STR and the cleaner who had 14 yr construction experience is saying I'll need to hire an excavator to deal with the issue from the outside. It seems to just be a small leak in my bathroom from heavy rain the night before and was trying to fix it with hydraulic cement from the inside. Unfortunately I don't have any pictures but it's a stone foundation. Seems pretty drastic to bring in an excavator here. Any ideas?

Thanks!
