We hired someone to place tiles in a bathroom remodel. He quoted us a price and a time of 3 to 4 days by himself or maybe 1 if he brought a helper. We paid half down, and 13 days after the project began, we told him we were not going to us him and longer and finished the project ourselves. He would say he would show up, then after calling him said he had other jobs requiring his attention, or the person he was sending over did not show up. This was a constant issue - that is just getting him to show up. He demanded 1700 more, and we told him we would pay for the time he was there. He then said another 1000 and he would leave, again more than the last half of the quote. His work was shoddy and sloppy and 9 days over due. We had to clean thin set out of the toilet flange, we had to regrout parts that he missed, we laid the last 10% of tiles our selves, and grouted the shower walls and floor. We did prep work and clean up everyday he was there working. We provided all supplies and even bought tools he was missing. He is saying he is putting a lien against the house due to non payment. We tried to settle with him, but he kept demanding more money. Also the person who hired him is not the home owner. Any advice on this situation?
