We hired a contractor to paint our pool. He didnt showup and did very little work. We never signed a contract and he kept giving us invoices charging us more. He just gave us a notice of right to lien. This all started March 23 and we fired him a week ago on Wednesday. He had written on the invoices that he would have the pool completed by the 14th of April. He just started draining the pool on the 20th of April then left for a week. We are not sure what to do. He wants $750.00 for the work he has done. He was here for about 6 hrs total and did very little work in the 6 hrs. On his invoices it breaks done what he charges for each work he performs so I was going off his invoice to how much we owe him. Which is about $500.00 to $600.00.
