Firing a Subcontractor, how do I keep proper documentation?

[Ashley Kebreau]

Hello BP! I just purchased my first live in flip and hired a guy how does floor...and so i thought. I paid 50% and he started the work. During the process i noticed areas that weren't done correctly so i pointed them out and took pictures and sent them to him to fix. He ' finished ' the job and i re-inspected and still the areas of unfinished/ incorrect work weren't fixed. At this point fired him and decided to take it out and start over on the DIY path to save the already wasted $$$ and time. How can I properly document this in case he tries to come back for the remaining 50%? Are photos enough? Do i need to email the pictures with an explanation of the firing to him as well? We haven't been in contact for a week know but I just want to make sure I have proof and documentation done correctly. Thank you for your advice
