Ace contracted with Jones to do certain remodelling work on the building owned by Jones. Jones supplied the specifications for the work. The contract price was $70,000. After the work was completed, Jones was dissatisfied and had Clay, an expert, compare the work done with the specifications provided. Clay testified that the work had been done improperly by Ace and that it would case about $6,000 to correct the mistakes of Ace. If Jones refuses to pay any amount to Ace, what recourse, if any, does Ace have against Jones? Explain.
