I am having my kitchen remodeled and hired a contractor on May 28th, 2010. I signed a contract and gave them a deposit for $ 7,100.00, which is half of what the job will cost. It says on the contract that the approximate starting date would be 6 weeks after the contract was signed. It is now August 4th and they haven't started yet and give me no specific time when they will start. When would they be held liable for breeching the contract by not starting when they promised.
