Questions about license bonding and insurance

[JD Mims]

Hello to the BRRR family! I'm reading about license bonding and insurance for contractors and I'm wondering if anyone can shed some light.

Since the contractor already has a bond how do I, as the hiring party use this for my protection? 

Doesn't the bond guarantee that the work is performed to our contract agreement? Do I need to ask for information about the bond? or call the bond company? How do I utilize what's already in place for my protection?

I appreciate your time and help. 

Thanks.
