If I were you, I'd learn from this experience and try to avoid further confrontations with the guy. And I'd have a long discussion with anyone doing work on your property advising them to be neighborly toward your neighbors, and when they are done, I'd inspect not only my property but adjacent properties as well.

Good luck.
