We engaged a contractor through Coldwell Bankers RealVitalize program. He was suggested by our listing agent. The remodel was to put in a new tub/shower and tile and new walls. Long story short, he did not finish the job we engaged him for- numerous items from the contract/itemized estimate were not completed. He destroyed an existing window and trim, did very shoddy finish work, left cracks in our walls and put in a new floor that is uneven and bumpy. the re installed toilet is on a tilt and runs. the new shower head is not firmly mounted and the whole tub unit leaks. Another contractor reviewed the work and said it all needs to be gutted due to improper construction. The pipes were left hanging in the wall and not secured to anything or anchored. We did not pay him the second half of the invoice total as the job is sub par, incomplete, and the bathroom non functional. Coldwell's program put the initial deposit down and are trying to recoup that money. Can he put a lien on our home or sue us for the balance?
