Siding replacement contract

[ringgirl]

What is the name of your state? NJ I signed a contract with a construction company to replace the siding on my house due to hail damage. The contract was signed in Jan. 07 and the deposit paid on Feb. 2, 2007. They have not started any work as of May 22, 2007 and I have not heard from them since except once when they delivered the wrong siding and I had to tell them and get them to come get it (which took 6 weeks). They had contracts to do many of the houses in my neighborhood and now at least half the people are suing them. Can I get out of this contract? Is their delay in starting work considered a breach?What is the name of your state?
