Issue with contractor

[Kyle Nigro]

I purchased a flip a few weeks back.  The contractor I had working for me gave me a spreadsheet of the costs, but nothing was ever signed.  He said it was “in good faith” after one of his managers made some critical mistakes on the first estimate.  I should have left them the first time…

Long story short, minimal work was done within the scope and I’m looking to move on. what am I legally obligated to pay him when minimal work was done?  He told me he was to get his attorney involved, but I don’t have a contract or anything with this company.

I have another company lined up but I don’t want to burn any bridges.  How should I approach this?

Thanks!
