We contracted with a local remodel company. We informed the company of our budget for the bathroom remodels. There was a total of three bathrooms that were to be done. We have a signed contract and an email that includes from him the scope of work. We were given budgets for tile and flooring, he picked lights for 2 bathrooms. Hardware was not specified in the contract but we purchased this at our costs. He received 1/3 at signing then another 1/3 once he had completed 2 bathrooms with some small items that needed to be addressed. We then also gave him another 5000.00 draw on the total contract. We did have him sign the receipt of these payments on our copy of the contract. Work is almost complete but he approached my husband yesterday Friday and demanded 5000.00 more dollars for change orders. We have not signed any change orders and the contract specifically says that all change orders be in writing and signed by both parties. He walked off the job asked for his tools which we let him have he also too all the materials that were being used for the job paint, tile and flooring. The floor and tile work have been completed with the exception of a small area that needs grout. We still owe him 8650.00 but the job is not complete. We are missing the floating and painting of the master bath and bedroom, the shower door and the shower head. There is also some additional cabinet work for the closets bathroom cabinets. He has stated unless we give him an additional 5000.00 and the balance to complete the job he will put a lean on our home. What are our options?
