Contractors found drinking on the job

[Evan Staats]

Looking for some legal advice here.

I hired a company to replace flooring, tile, and deck boards at my newly purchased Airbnb. They completed the work, in about 2 weeks,  with many issues found in the middle and end of their work.  I brought up most of the issues along the way, and again at the end. They were never fixed once I addressed them between the two weeks. After the onsite contractors were finally finished with all the work, I found all the issues not to be fixed. I then took pictures of everything and coincidently found a garbage bag full of beer cans and two 12-pack beer boxes in the house. So the two guys at the house either drank the alcohol in 3 days or all in one day, while doing the work. Either way, they were drinking while on the job and at my personal property and place of business. 

Is there anything legally I can do as the customer/should do for this blatant disregard for workplace policies and respect toward personal property?

Thank you
