I had a job that I originally contracted which had insurance that covered painting, drywall, and carpentry. I also did tile on this job as it is just like carpentry. This was a year long job. I no longer have the same insurance as I was planning on retiring. I kept some interior painting insurance because I had one job to do after this. The customer thinks the shower needs to be rebuilt at a high cost and I do not agree. It has some small things to address. I performed this job after the other insurance I had was gone. I explained to him what I would do to address his concerns about the shower and he refused. He then fired me after working there for a year with only %600 due at the end. I had no coverage for the tile. just paint. Is this a legal problem for me?
