I have a contractor. I had a new floor poured and there is lots of cracking and the floor looks really bad
You may want to pursue termination for cause in regards to the poor workmanship conducted by the contractor. Termination for cause is when a construction business is terminated for failing to execute its contract. These terminations occur and are reserved for substantial issues and repeated shortcomings. However, the terms of your construction contract will set out exactly how the termination will occur and what events would justify the termination.
