The agreement was made to complete the foundation work as per plan at the amount of $20,000. The contract received $17,000 from the owner but just finish one third of the work with the delay. The work was failed on the inspection by City Hall and the engineering report require to remove the concrete wall and redo it. The contract had many excuses to delay the work and now refuse to do the work at their cost. The contractor refuse to take a phone call neither the response from email.
The only information from the contractor is the name and the address of this small company, the name of the owner/partner. In order to get the loss (money) back from the contractor after the case is awarded the court, what other information should be collected before suing to the court? Should I terminate the agreement by sending a letter to the address of the contractor’s company? Would this address of the contractor's company be accepted as "service" delivered?
