In four years of this company I haven't had one guy who refuse to pay for the work. Even after we stay after hours to fix all the bogus claims to the project. Even after he said everything look fine he refuse to pay. He told me he doesn't want to pay because I took a week longer that what we plan. But I have an email where he informs me that the material won't arrive until this week that is why we took this long to complete the project. He told me he is going to trash me in Angie's list, but I'm not scared since this would be my first bad review of about 60. He told me he would take me to court but he has no claim. I completed the work. Now I have to hire a lawyer, put a lean on his home and start this process. Since is my first time doing this can any of you give me any tips.
