Hello - I hired a handyman to build a deck for me on my property. He made many mistakes that I kept having to identify and have him fix performing very poor work, and over inflated his labor charges. He could have also over charged me for materials as I never saw those bill and things would need returned and he claimed he didn't charge me, but I would never really know. He never put down how many hours he worked on his weekly bills just a large lump sum of money. I started questioning it on his last bill after many mistakes were made and the bill was getting out of budget. So I made him report on his hours and what he was actually doing. His last bill was way out of line and I was over charged. He did not have an explanation for it and I did refused to pay that labor in full as it wasn't accurate. He has now been threatening me in many ways, one of which is to file a lien on my house starting now. He never had a contract or anything in writing. He also convinced me I didn't need to get a city permit. Does he have any ground to stand on and what can I do to protect myself and my hard earned investment? Thank you, Tiffany
